Dear Fellow Shareholders,

The stock market made little, if any, headway year-to-date through October
2004, as it wrestled with a variety of uncertainties. Questions about the
continuing strength of the economy, the effects of rising interest rates
and expectations for corporate earnings growth kept investors jittery. In
addition, record high crude oil prices, geopolitical issues and a closely
contested U.S. presidential race all weighed on the market. The picture
brightened in early November with the election over and oil prices
moderating somewhat.

Year-to-date through October 31, 2004, the Standard & Poor's 500 Index was
up 3.06%, while the Dow Jones Industrial Average and the Nasdaq Composite
Index were slightly negative, returning -2.40% and -1.05%, respectively.
Despite the Federal Reserve's three hikes in short-term interest rates from
historic lows, bonds still managed to outperform stocks, with the Lehman
Brothers Aggregate Bond Index up 4.22%.

In news closer to home, we are pleased to announce that on June 15, 2004,
your fund's Board of Trustees appointed Charles L. Ladner as independent
Chairman of the Board of Trustees, a position previously held by John
Hancock Funds LLC's former Chairman and Chief Executive Officer, Maureen
Ford Goldfarb. This appointment came in advance of new SEC regulations
requiring all mutual funds to have independent chairmen.

Mr. Ladner has served as an independent member of John Hancock Funds' Board
of Trustees since 1992 and formerly held the position of Senior Vice
President and Chief Financial Officer of UGI Corporation, a public utility
holding company in Valley Forge, PA, until his retirement in 1998. He
brings a wealth of knowledge, experience and leadership and we are
delighted to have him serve as Chairman.

Sincerely,

/S/ James A. Shepherdson

James A. Shepherdson,
Chief Executive Officer

  market chiefly due to uncertainty over the presidential election and
  product disappointments.

* The Fund benefited from good stock selection, particularly in the biotech
  and medical technology sectors.

* Large drug companies and generic drug makers disappointed investors due
  to pipeline and pricing concerns.

MANAGER'S
REPORT

JOHN HANCOCK
Health Sciences Fund

Health care stocks posted decent returns for the 12 months ended October
31, 2004, although they lagged the overall stock market primarily due to
the uncertainty over the outcome of the U.S. presidential election and
product-related disappointments. In the months leading up to the
cliffhanger race for the president, investors worried that a change in
administration would mean more regulation, would open the door to cheap
drugs from abroad, would impose price curbs and would tamper with the
recent Medicare reform initiatives. Product-related disappointments --
including Merck's recall of its arthritis treatment Vioxx after it was
shown to increase the risk of heart attacks and strokes, and Chiron's
inability to ship flu vaccine after the U.K. suspended manufacturing of the
product -- clouded the outlook for some segments of the health care group
in the final months of the period. That said, there were plenty of
positives for the health care sector during the year. Investors generally
rewarded companies with innovative and exciting products, as well as those
that continued to improve operational performance through cost control and
efficiency programs.

"Health care stocks posted decent
 returns for the 12 months ended

Performance review

For the 12 months ended October 31, 2004, John Hancock Health Sciences
Fund's Class A, Class B and Class C shares posted total returns of 8.62%,
7.86% and 7.86%, respectively, at net asset value. During the same one-year
period, the Russell 3000 Healthcare Index returned 3.02% and the average
health/biotechnology fund had a total return of 5.93%, according to Lipper,
Inc.,1 while the Standard & Poor's 500 Index returned 9.42%. Keep in mind
that your net asset value return will be different from the Fund's
performance if you were not invested in the Fund for the entire period and
did not reinvest all distributions. See pages six and seven for historical
performance results.

Managed care, biotechs top the charts

At the top of our best-performers list during the year were a number of
managed care holdings, including UnitedHealth Group, Wellpoint Health and
Anthem, Inc. These companies derived earnings increases from hefty
health-care premium hikes they charged their customers, which more than
offset the rising medical costs the HMOs incurred. They also benefited from
their focus on enhancing productivity, controlling costs and improving
their balance sheets.

Many of our biotech holdings also performed quite well this year. Our
biggest winners were OSI Pharmaceuticals and Biogen Idec. OSI's stock price
began zooming higher in June on news that its experimental cancer drug
Tarceva had extended survival in late-stage lung cancer patients. Tarceva
is what's known as an epidermal growth factor receptor inhibitor that
shrinks tumors by blocking proteins that promote the spread of cancer
cells. In the fall, the stock got another boost when the company announced
that it had received fast-track regulatory approval from the Food and Drug
Administration for Tarceva, meaning the agency has six months from the
application receipt date, or until January 30, 2005, to take action. OSI is
developing the drug with Genentech, another of the Fund's larger and
better-performing holdings during the year.

"At the top of our best-performers
 list during the year were a number
 of managed care holdings..."

Biogen Idec's shares also posted strong gains in part due to excitement
over the company's Antegren drug to treat multiple sclerosis. The drug may
launch later this year or early in 2005. Another winner was Eyetech
Pharmaceuticals, which was buoyed by investors' enthusiasm over the
company's experimental treatment Macugen, a drug for the sight-robbing
disease called wet age-related macular degeneration. Investors also liked
the fact that the company has plenty of financial support from its
marketing and development partner Pfizer. We also enjoyed good gains from
our holdings in Tularik, which was lifted mid-year by news that the company
- -- which develops potential therapies for cancer, diabetes and obesity --
was to be acquired by Amgen, the world's largest biotech company.
Unfortunately, Amgen's stock moved sideways for most of the year despite
continuing strong sales and profits from its drugs for anemia and
arthritis.

The first listing is Health care equipment 27%, the second is Biotechnology
26%, the third is Pharmaceuticals 20%, the fourth is Health care services 11%
and the fifth is Managed health care 6%.]

Our focus on medical device companies also aided performance. St. Jude
Medical posted rising profits thanks to robust sales of its new product
used to treat heart failure. Device makers Medtronic and Guidant also
performed well, particularly after the Centers for Medicare and Medicaid
Services announced that they would expand reimbursement coverage of cardiac
defibrillator devices to new patients.

Drug companies falter

Our underweighting in big drug companies, which came under pressure due to
political and pipeline concerns, helped us, but our holdings in generic
drug companies generally detracted from performance. Generic drug makers --
including Mylan Laboratories, Barr Pharmaceuticals and Watson
Pharmaceuticals -- were hurt by increased competition and pressure to
reduce prices. We also suffered losses with Chiron, which plummeted on news
that U.K. authorities prohibited the company from shipping Fluvirin this
season, which accounts for about 50% of the flu vaccines sold in the U.S.

percentage of net assets on 10-31-04." The chart is divided into two

Outlook

We're reasonably optimistic about the prospects for health care stocks. The
world's aging population provides strong underpinnings for the bullish
future of health care stocks over the long term. We believe that there are
other, more near-term factors working in the group's favor. Just after the
Fund's fiscal year ended, President Bush was re-elected to a second term.
That seemed to reassure investors that status quo, rather than radical

change, will be the watchwords for national health-care policies.
Furthermore, the fact that the economy is growing at a modest pace is a
positive. Historically speaking, health care companies tend to do best in
that environment because more robust economic growth tends to attract
investors to faster-growing segments of the market. Given those relatively
benign external factors, the performance of health care stocks likely will
hinge on innovation, new product approval and valuations. We're impressed
with the current pace of innovation, although new product approvals may
slow somewhat as the FDA takes a more cautious view in light of recent
developments with Merck and Chiron. In terms of valuations, there remain
many reasonably priced opportunities, although some stocks appear to have
gotten too expensive. In our view, those factors all add up to an
environment that we believe plays to our stock-picking strengths.

"We're reasonably optimistic about
 the prospects for health care stocks."

A LOOK AT
PERFORMANCE

For the period ended
October 31, 2004

                                           Class A      Class B      Class C

Performance figures assume all distributions are reinvested. Returns with
maximum sales charge reflect a sales charge on Class A shares of 5%, and
the applicable contingent deferred sales charge (CDSC) on Class B and Class
C shares. The returns for Class C shares have been adjusted to reflect the
elimination of the front-end sales charge effective July 15, 2004. The
Class B shares' CDSC declines annually between years 1--6 according to the
following schedule: 5, 4, 3, 3, 2, 1%. No sales charge will be assessed
after the sixth year. Class C shares held for less than one year are
subject to a 1% CDSC. The return and principal value of an investment in
the Fund will fluctuate, so that shares, when redeemed, may be worth more
or less than the original cost.

The returns reflect past results and should not be considered indicative of
future performance. The performance table above and the chart on the next
page do not reflect the deduction of taxes that a shareholder would pay on
fund distributions or the redemption of fund shares.

The Fund's performance results reflect any applicable expense reductions,
without which the expenses would increase and results would have been less
favorable.

YOUR
EXPENSES

These examples are intended to help you understand your ongoing operating
expenses.

Understanding fund expenses

As a shareholder of the Fund, you incur two types of costs:

* Transaction costs which include sales charges (loads) on purchases or
  redemptions (varies by share class), minimum account fee charge, etc.

* Ongoing operating expenses including management fees, distribution and
  service fees (if applicable) and other fund expenses.

We are going to present only your ongoing operating expenses here.

Actual expenses/actual returns

This example is intended to provide information about your fund's actual
ongoing operating expenses, and is based on your fund's actual return. It
assumes an account value of $1,000.00 on April 30, 2004, with the same
investment held until October 31, 2004.


Account value                                              Expenses paid
$1,000.00                             Ending value         during period
on 4-30-04                             on 10-31-04        ended 10-31-04 1
- --------------------------------------------------------------------------
Class A                                    $928.90                 $7.68
Class B                                     925.60                 11.05
Class C                                     925.60                 11.05


Together with the value of your account, you may use this information to
estimate the operating expenses that you paid over the period. Simply
divide your account value at October 31, 2004 by $1,000.00, then multiply
it by the "expenses paid" for your share class from the table above. For
example, for an account value of $8,600.00, the operating expenses should
be calculated as follows:

Example

 --                                --      --              --
| My account value  /                |    | "expenses paid"  |      My
|                  / $1,000.00 = 8.6 | X $|                  | =  actual
|    $8,600.00    /                  |    |    from table    |   expenses
 --                                --      --              --

Hypothetical example for comparison purposes

This table allows you to compare your fund's ongoing operating expenses
with those of any other fund. It provides an example of the Fund's
hypothetical account values and hypothetical expenses based on each class's
actual expense ratio and an assumed 5% annual return before expenses (which
is not your fund's actual return). It assumes an account value of $1,000.00
on April 30, 2004, with the same investment held until October 31, 2004.
Look in any other fund shareholder report to find its hypothetical example
and you will be able to compare these expenses.

Remember, these examples do not include any transaction costs, such as
sales charges; therefore, these examples will not help you to determine the
relative total costs of owning different funds. If transaction costs were
included, your expenses would have been higher. See the prospectus for
details regarding transaction costs.

1 Expenses are equal to the Fund's annualized expense ratio of 1.58%, 2.28%
  and 2.28% for Class A, Class B and Class C, respectively, multiplied by the
  average account value over the period, multiplied by [number of days in
  most recent fiscal half-year/365 or 366] (to reflect the one-half year
  period).

NOTES TO
STATEMENTS


Note A
Accounting policies

John Hancock Health Sciences Fund (the "Fund") is a non-diversified series
of John Hancock World Fund, an open-end management investment company
registered under the Investment Company Act of 1940. The investment
objective of the Fund is to achieve long-term growth of capital.

The Trustees have authorized the issuance of multiple classes of shares of
the Fund, designated as Class A, Class B and Class C shares. The shares of
each class represent an interest in the same portfolio of investments of
the Fund and have equal rights as to voting, redemptions, dividends and
liquidation, except that certain expenses, subject to the approval of the
Trustees, may be applied differently to each class of shares in accordance
with current regulations of the Securities and Exchange Commission and the
Internal Revenue Service. Shareholders of a class that bears distribution
and service expenses under the terms of a distribution plan have exclusive
voting rights to that distribution plan.

Significant accounting policies
of the Fund are as follows:

Valuation of investments

Securities in the Fund's portfolio are valued on the basis of market
quotations, valuations provided by independent pricing services or, if
quotations are not readily available, or the value has been materially
affected by events occurring after the closing of a foreign market, at fair
value as determined in good faith in accordance with procedures approved by
the Trustees. Short-term debt investments, which have a remaining maturity
of 60 days or less may be valued at amortized cost which approximates
market value. Investments in AIM Cash Investment Trust are valued at their
net asset value each business day. All portfolio transactions initially
expressed in terms of foreign currencies have been translated into U.S.
dollars as described in "Foreign currency translation" below.

Joint repurchase agreement

Pursuant to an exemptive order issued by the Securities and Exchange
Commission, the Fund, along with other registered investment companies
having a management contract with John Hancock Advisers, LLC (the
"Adviser"), a wholly owned subsidiary of John Hancock Financial Services,
Inc., may participate in a joint repurchase agreement transaction.
Aggregate cash balances are invested in one or more large repurchase
agreements, whose underlying securities are obligations of the U.S.
government and/or its agencies. The Fund's custodian bank receives delivery
of the underlying securities for the joint account on the Fund's behalf.
The Adviser is responsible for ensuring that the agreement is fully
collateralized at all times.


21



Foreign currency
translation

All assets or liabilities initially expressed in terms of foreign
currencies are translated into U.S. dollars based on London currency
exchange quotations as of 4:00 P.M., London time, on the date of any
determination of the net asset value of the Fund. Transactions affecting
statement of operations accounts and net realized gain (loss) on
investments are translated at the rates prevailing at the dates of the
transactions.

The Fund does not isolate that portion of the results of operations
resulting from changes in foreign exchange rates on investments from the
fluctuations arising from changes in market prices of securities held. Such
fluctuations are included with the net realized and unrealized gain or loss
from investments.

Reported net realized foreign currency exchange gains or losses arise from
sales of foreign currency, currency gains or losses realized between the
trade and settlement dates on securities transactions and the difference
between the amounts of dividends, interest and foreign withholding taxes
recorded on the Fund's books and the U.S. dollar equivalent of the amounts
actually received or paid. Net unrealized foreign currency exchange gains
and losses arise from changes in the value of assets and liabilities, other
than investments in securities, resulting from changes in the exchange
rates.

Investment transactions

Investment transactions are recorded as of the date of purchase, sale or
maturity. Net realized gains and losses on sales of investments are
determined on the identified cost basis. Capital gains realized on some
foreign securities are subject to foreign taxes, which are accrued as
applicable.

Class allocations

Income, common expenses and realized and unrealized gains (losses) are
determined at the fund level and allocated daily to each class of shares
based on the appropriate net asset value of the respective classes. Distri
bution and service fees, if any, are calculated daily at the class level
based on the appropriate net asset value of each class and the specific
expense rate(s) applicable to each class.

Expenses

The majority of expenses are directly identifiable to an individual fund.
Expenses that are not readily identifiable to a specific fund will be
allocated in such a manner as deemed equitable, taking into consideration,
among other things, the nature and type of expense and the relative sizes
of the funds.

Bank borrowings

The Fund is permitted to have bank borrowings for temporary or emergency
purposes, including the meeting of redemption requests that otherwise might
require the untimely disposition of securities. The Fund has entered into a
syndicated line of credit agreement with various banks. This agreement
enables the Fund to participate with other funds managed by the Adviser in
an unsecured line of credit with banks, which permits borrowings of up to
$250 million, collectively. Interest is charged to each fund, based on its
borrowing. In addition, a commitment fee is charged to each fund based on
the average daily unused portion of the line of credit and is allocated
among the participating funds. The Fund had no borrowing activity under the
line of credit during the year ended October 31, 2004.

Securities lending

The Fund may lend securities to certain qualified brokers who pay the Fund
negotiated lender fees. The loans are collateralized at all times with cash
or securities with a market value at least equal to the market value of the
securities on loan. As with other extensions of credit, the Fund may bear
the risk of delay of the loaned securities in recovery or even loss of
rights in the collateral, should the borrower of the securities fail
financially. On October 31, 2004, the Fund loaned securities having a
market value of $84,985,627


22



collateralized by cash in the amount of $86,621,709. The cash collateral
was invested in a short-term instrument. Security lending expenses are
paid by the Fund to the Adviser.

Federal income taxes

The Fund qualifies as a "regulated investment company" by complying with
the applicable provisions of the Internal Revenue Code and will not be
subject to federal income tax on taxable income that is distributed to
shareholders. Therefore, no federal income tax provision is required.

Dividends, interest
and distributions

Dividend income on investment securities is recorded on the ex-dividend or,
in the case of some foreign securities, on the date thereafter when the
Fund identifies the dividend. Interest income on investment securities is
recorded on the accrual basis. Foreign income may be subject to foreign
withholding taxes, which are accrued as applicable.

The Fund records distributions to shareholders from net investment income
and net realized gains, if any, on the ex-dividend date. Distributions paid
by the Fund with respect to each class of shares are calculated in the same
manner, at the same time and are in the same amount, except for the effect
of expenses that may be applied differently to each class.

As of October 31, 2004, the components of distributable earnings on a tax
basis were $10,199,370 of undistributed long-term gain.

Such distributions and distributable earnings, on a tax basis, are
determined in conformity with income tax regulations, which may differ from
accounting principles generally accepted in the United States of America.
Distributions in excess of tax basis earnings and profits, if any, are
reported in the Fund's financial statements as a return of capital.

Use of estimates

The preparation of these financial statements, in accordance with
accounting principles generally accepted in the United States of America,
incorporates estimates made by management in determining the reported
amount of assets, liabilities, revenues and expenses of the Fund. Actual
results could differ from these estimates.


Note B
Management fee and
transactions with
affiliates and others

The Fund has an investment management contract with the Adviser. Under the
investment management contract, the Fund pays a quarterly management fee to
the Adviser equivalent, on an annual basis, to the sum of: (a) 0.80% of the
first $200,000,000 of the Fund's average daily net asset value and (b)
0.70% of the Fund's average daily net asset value in excess of
$200,000,000.

The Fund has an agreement with its custodian bank under which custody fees
are reduced by brokerage commissions offsets applied during the period.
Accord ingly, the expense reductions related to custody fee offsets
amounted to $370, and had no impact on the Fund's ratio of expenses to
average net assets for the year ended October 31, 2004.

The Fund has Distribution Plans with John Hancock Funds, LLC ("JH Funds"),
a wholly owned subsidiary of the Adviser. The Fund has adopted Distribution
Plans with respect to Class A, Class B and Class C pursuant to Rule 12b-1
under the Investment Company Act of 1940 to reimburse JH Funds for the
services it provides as distributor of shares of the Fund. Accordingly, the
Fund makes monthly payments to JH Funds at an annual rate not to exceed
0.30% of Class A average daily net asset value and 1.00% of Class B and
Class C average daily net asset value. A maximum of 0.25% of such payments
may be service fees as defined by the Conduct Rules of the National
Association of Securities Dealers. Under the Conduct Rules, curtailment of
a portion of the Fund's 12b-1 payments could occur under certain
circumstances.

Class A shares are assessed up-front sales charges.


23



During the year ended October 31, 2004, JH Funds received net up-front
sales charges of $185,741 with regard to sales of Class A shares. Of this
amount, $26,095 was retained and used for printing prospectuses,
advertising, sales literature and other purposes, $123,039 was paid as
sales commissions to unrelated broker-dealers and $36,607 was paid as
sales commissions to sales personnel of Signator Investors, Inc.
("Signator Investors"), a related broker-dealer. The Adviser's indirect
parent, John Hancock Life Insurance Company ("JHLICo"), is the indirect
sole shareholder of Signator Investors. Prior to July 15, 2004, Class C
shares were assessed up-front sales charges. During the year ended October
31, 2004, JH Funds received net up-front sales charges of $16,227 with
regard to sales of Class C shares. Of this amount, $15,688 was paid as
sales commissions to unrelated broker-dealers and $539 was paid as sales
commissions to sales personnel of Signator Investors.

Class B shares that are redeemed within six years of purchase are subject
to a contingent deferred sales charge ("CDSC") at declining rates,
beginning at 5.00% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed.
Class C shares that are redeemed within one year of purchase are subject to
a CDSC at a rate of 1.00% of the lesser of the current market value at the
time of redemption or the original purchase cost of the shares being
redeemed. Proceeds from the CDSCs are paid to JH Funds and are used in
whole or in part to defray its expenses for providing distribution related
services to the Fund in connection with the sale of Class B and Class C
shares. During the year ended October 31, 2004, CDSCs received by JH Funds
amounted to $242,814 for Class B shares and $555 for Class C shares.

The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc. ("Signature Services"), an indirect subsidiary of JHLICo.
For Class A, Class B and Class C shares, the Fund pays a monthly transfer
agent fee at an annual rate of 0.05% of the each class's average daily net
asset value, plus a fee based on the number of shareholder accounts and
reimbursement for certain out-of-pocket expenses aggregated and allocated
to each class on the basis of its relative net asset value. Signature
Services agreed to voluntarily reduce the Fund's asset-based portion of the
transfer agent fee if the total transfer agent fee exceeds the Lipper, Inc.
median transfer agency fee for comparable mutual funds by 0.05%. There were
no transfer agent fee reductions during the year ended October 31, 2004.
Signature Services reserves the right to terminate this limitation at any
time.

The Fund has an agreement with the Adviser to perform necessary tax,
accounting and legal services for the Fund. The compensation for the year
amounted to $80,623. The Fund also paid the Adviser the amount of $755 for
certain publishing services, included in the printing fees.

Mr. James A. Shepherdson is a director and/or officer of the Adviser and/or
its affiliates, as well as Trustee of the Fund. The compensation of
unaffiliated Trustees is borne by the Fund. The unaffiliated Trustees may
elect to defer, for tax purposes, their receipt of this compensation under
the John Hancock Group of Funds Deferred Compensation Plan. The Fund makes
investments into other John Hancock funds, as applicable, to cover its
liability for the deferred compensation. Investments to cover the Fund's
deferred compensation liability are recorded on the Fund's books as an
other asset. The deferred compensation liability and the related other
asset are always equal and are marked to market on a periodic basis to
reflect any income earned by the investments, as well as any unrealized
gains or losses. The Deferred Compensation Plan investments had no impact
on the operations of the Fund.

Note D
Investment
transactions

Purchases and proceeds from sales or maturities of securities other than
short-term securities and obligations of the U.S. government, during the
year ended October 31, 2004, aggregated $156,021,664 and $187,937,528,
respectively.

The cost of investments owned on October 31, 2004, including short-term
investments, for federal income tax purposes was $283,023,554. Gross
unrealized appreciation and depreciation of investments aggregated
$76,622,172 and $2,644,242, respectively, resulting in net unrealized
appreciation of $73,977,930. The difference between book basis and tax
basis net unrealized appreciation of investments is attributable primarily
to the tax deferral of losses on certain sales of securities.

Note E
Reclassification
of accounts

During the year ended October 31, 2004, the Fund reclassified amounts to
reflect an increase in accumulated net realized gain on investments of
$18,929, a decrease in accumulated net investment loss of $4,375,919 and a
decrease in capital paid-in of $4,394,848. This represents the amount
necessary to report these balances on a tax basis, excluding certain
temporary differences, as of October 31, 2004. Additional adjustments may
be needed in subsequent reporting periods. These reclassifications, which
have no impact on the net asset value of the Fund, are primarily
attributable to certain differences in the computation of distributable
income and capital gains under federal tax rules versus accounting
principles generally accepted in the United States of America, and book and
tax differences in accounting for net operating loss, deferred compensa
tion and certain foreign currency adjustments. The calculation of net
investment loss per share in the Fund's Finan cial Highlights excludes
these adjustments.

Trustees were elected to the Fund's Board of Trustees. Several Trustees
had reached the age for mandatory retirement and plan to retire in 2004
and 2005. The Board of Trustees recommended and shareholders approved a
proposal to consolidate the two panels into one Board of Trustees for all
open-end funds within the John Hancock funds complex. The effective date
for the newly elected Trustees to the Fund will be January 1, 2005.

AUDITORS'
REPORT

Report of
Pricewaterhouse-
Coopers LLP,
Independent
Registered Public
Accounting Firm

To the Board of Trustees and Shareholders of
John Hancock Health Sciences Fund,

In our opinion, the accompanying statement of assets and liabilities,
including the schedule of investments, and the related statements of
operations and of changes in net assets and the financial highlights
present fairly, in all material respects, the financial position of the
John Hancock Health Sciences Fund (the "Fund") at October 31, 2004, the
results of its operations, the changes in its net assets and the financial
highlights for the periods indicated, in conformity with accounting
principles generally accepted in the United States of America. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management;
our responsibility is to express an opinion on these financial statements
based on our audits. We conducted our audits of these financial statements
in accordance with the standards of the Public Company Accounting Oversight
Board (United States). Those standards require that we plan and perform the
audits to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining,
on a test basis, evidence supporting the amounts and disclosures in the
financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which
included confirmation of securities at October 31, 2004, by correspondence
with the custodian and brokers, provide a reasonable basis for our opinion.

Dear Fellow Shareholders,

The stock market made little, if any, headway year-to-date through October
2004, as it wrestled with a variety of uncertainties. Questions about the
continuing strength of the economy, the effects of rising interest rates
and expectations for corporate earnings growth kept investors jittery. In
addition, record high crude oil prices, geopolitical issues and a closely
contested U.S. presidential race all weighed on the market. The picture
brightened in early November with the election over and oil prices
moderating somewhat.

Year-to-date through October 31, 2004, the Standard & Poor's 500 Index was
up 3.06%, while the Dow Jones Industrial Average and the Nasdaq Composite
Index were slightly negative, returning -2.40% and -1.05%, respectively.
Despite the Federal Reserve's three hikes in short-term interest rates from
historic lows, bonds still managed to outperform stocks, with the Lehman
Brothers Aggregate Bond Index up 4.22%.

In news closer to home, we are pleased to announce that on June 15, 2004,
your fund's Board of Trustees appointed Charles L. Ladner as independent
Chairman of the Board of Trustees, a position previously held by John
Hancock Funds LLC's former Chairman and Chief Executive Officer, Maureen
Ford Goldfarb. This appointment came in advance of new SEC regulations
requiring all mutual funds to have independent chairmen.

Mr. Ladner has served as an independent member of John Hancock Funds' Board
of Trustees since 1992 and formerly held the position of Senior Vice
President and Chief Financial Officer of UGI Corporation, a public utility
holding company in Valley Forge, PA, until his retirement in 1998. He
brings a wealth of knowledge, experience and leadership and we are
delighted to have him serve as Chairman.

Sincerely,

/S/ James A. Shepherdson

James A. Shepherdson,
Chief Executive Officer

MANAGER'S
REPORT

JOHN HANCOCK
Biotechnology Fund

Biotechnology stocks posted decent returns for the 12 months ended October
31, 2004, although they fared far better in the first half of the period
than they did in the second. Much of the sector's early strength can be
traced to relatively strong economic conditions, which fueled demand for
faster growing stocks, as well as positive clinical trial results and a
rise in product approvals. But as robust economic growth gave way to more
anemic conditions, biotech and other fast-growing stock sectors started to
fade when investors gravitated to more stable, defensive sectors. Weakened
equity markets called into question the ability of some biotech companies
to tap them for funding. Other difficulties confronting biotechs included
worries that a change in the White House would mean more regulation, open
the door to cheap drugs from abroad, impose price curbs and tamper with the
recent Medicare reform initiatives. Product-related disappointments further
clouded the outlook for biotech stocks in the final months of the period.

"Biotechnology stocks posted
 decent returns for the 12 months
 ended October 31, 2004, although
 they fared far better in the first
 half of the period than they did in
 the second."

Performance review

For the 12 months ended October 31, 2004, John Hancock Biotechnology Fund's
Class A, Class B and Class C shares posted total returns of 6.36%, 5.65%
and 5.65%, respectively, at net asset value. During the same one-year
period, the more broadly diversified average health/biotechnology fund had
a total return of 5.93%, according to Lipper, Inc.,1 while the Standard &
Poor's 500 Index returned 9.42% and the Nasdaq Biotechnology Index returned
- -2.81%. Keep in mind that your net asset value return will be different
from the Fund's performance if you were not invested in the Fund for the
entire period and did not reinvest all distributions. See pages six and
seven for historical performance results. The Fund's outperformance of its
peers and benchmark Nasdaq Biotechnology Index can be attributed primarily
to strong stock selection within the health care group.

New drugs boost leaders

At the top of our best-performers list were OSI Pharmaceuticals and Biogen
Idec. OSI's stock price began zooming higher in June on news that its
experimental cancer drug Tarceva had extended survival in late-stage lung
cancer patients. Tarceva is what's known as an epidermal growth factor
receptor inhibitor that shrinks tumors by blocking proteins that promote
the spread of cancer cells. In the fall, the stock got another boost when
the company announced that it had received fast-track regulatory approval
from the Food and Drug Administration for Tarceva, meaning the agency has
six months from the application receipt date, or until January 30, 2005, to
take action. Biogen Idec's shares also posted strong gains in part due to
excitement over the company's Antegren drug to treat the symptoms of
multiple sclerosis, which may launch later this year. Another winner was
Eyetech Pharmaceuticals, which was buoyed by investors' enthusiasm over the
company's experimental treatment Macugen, a drug for the sight-robbing
disease called wet age-related macular degeneration. Investors also liked
the fact that the company has plenty of financial support from its
marketing and development partner Pfizer. We also enjoyed good gains from
our holdings in Tularik, which was lifted mid-year by news that the company
- -- which develops potential therapies for cancer, diabetes and obesity --
was to be acquired by Amgen, the world's largest biotech company.
Unfortunately, Amgen's stock stumbled in reaction to concerns about new
pricing guidelines for its chemotherapy-related products.

Other winners included Gilead Sciences, which enjoyed better-than-expected
financial results thanks to strong sales growth of its HIV treatments, and
Sepracor, which bounced back from a dismal 2003 thanks to clinical success
of its drug used to treat insomnia.

"Merger and acquisition
 activity provided the
 underpinnings for some of
 our other best performers."

"Urge to merge"

Merger and acquisition activity provided the underpinnings for some of our
other best performers. The stock price of Atrix Labs, which markets an
injectable prostate drug, was boosted on news that it would be acquired by
Vancouver-based biotech company QLT. Likewise, Ilex Oncology Inc, which
makes

a leukemia treatment, moved higher on news that Genzyme Corp. planned
to acquire it.

first listing is Biotechnology 67%; the second is Pharmaceuticals 14%, the
third is Health care equipment 10% and the fourth is Health care services 5%.]

Early stage companies fall out of favor

Companies dependent on the capital markets to fund their future growth fell
out of favor during the year and were among our biggest disappointments.
The main worry was that given the downturn in the stock market in the
second half of the period, some biotech companies wouldn't be able to raise
enough money to bring exciting and innovative products to market. Among our
holdings that were hurt by this development were Human Genome Sciences,
Amylin Pharmaceuticals, NPS Pharmaceuticals and Onyx Pharmaceuticals. We
also suffered losses with Chiron, which plummeted on news that U.K.
authorities prohibited the company from shipping Fluvirin this season,
which was to account for about 50% of the flu vaccines sold in the United
States. We sold the stock.

percentage of net assets on 10-31-04." The chart is divided into two
sections (from top to left): Common stocks 95%, and Short-term investments
& other 5%. ]

Outlook

We're reasonably optimistic about the prospects for biotech stocks. The
world's aging population provides strong support for a bullish outlook for
the group over the long term. We believe that there are other, more
near-term factors working in the group's favor. Just after the Fund's
fiscal year ended, President Bush was re-elected to a second term. That
seemed to reassure investors that status quo, rather than radical change,
will be the watchwords for national health care policies. Furthermore,
large biotech companies enjoy a marketplace that has high barriers to
entry, thereby limiting potential competition over the next year or so. But

of biotech stocks will continue to hinge on innovation, new product
approvals and valuations. We're impressed with the current pace of
innovation, although new product approval may slow somewhat as the FDA
takes a more cautious view in light of recent developments with Merck and
Chiron. In terms of valuations, there remain many reasonably priced
opportunities, although some stocks appear to have gotten too expensive.
Given that funding could remain an issue for smaller companies, they are
likely to remain the type of investment they've always been: more
speculative ventures with poten tially higher rewards. In our view, those
factors all add up to an environment that we believe plays to our
stock-picking strengths.

"We're reasonably optimistic about
 the prospects for biotech stocks."

A LOOK AT
PERFORMANCE

For the period ended
October 31, 2004

                              Class A      Class B      Class C
Inception date                 3-1-01       3-1-01       3-1-01

Average annual returns with maximum sales charge (POP)
One year                         1.03%        0.65%        4.65%
Since inception                 -7.64        -7.74        -6.98

Cumulative total returns with maximum sales charge (POP)
One year                         1.03         0.65         4.65
Since inception                -25.28       -25.60       -23.30

Performance figures assume all distributions are reinvested. Returns with
maximum sales charge reflect a sales charge on Class A shares of 5% and the
applicable contingent deferred sales charge (CDSC) on Class B and Class C
shares. The returns for Class C shares have been adjusted to reflect the
elimination of the front-end sales charge effective July 15, 2004. The
Class B shares' CDSC declines annually between years 1-6 according to the
following schedule: 5, 4, 3, 3, 2, 1%. No sales charge will be assessed
after the sixth year. Class C shares held for less than one year are
subject to a 1% CDSC. The return and principal value of an investment in
the Fund will fluctuate, so that shares, when redeemed, may be worth more
or less than the original cost.

The returns reflect past results and should not be considered indicative of
future performance. The performance table above and the chart on the next
page do not reflect the deduction of taxes that a shareholder would pay on
fund distributions or the redemption of fund shares.

The Fund's performance results reflect any applicable expense reductions,
without which the expenses would increase and results would have been less
favorable.

YOUR
EXPENSES

These examples are intended to help you understand your ongoing operating
expenses.

Understanding fund expenses

As a shareholder of the Fund, you incur two types of costs:

* Transaction costs which include sales charges (loads) on purchases or
  redemptions (varies by share class), minimum account fee charge, etc.

* Ongoing operating expenses including management fees, distribution and
  service fees (if applicable) and other fund expenses.

We are going to present only your ongoing operating expenses here.

Actual expenses/actual returns

This example is intended to provide information about your fund's actual
ongoing operating expenses, and is based on your fund's actual return. It
assumes an account value of $1,000.00 on April 30, 2004, with the same
investment held until October 31, 2004.


Account value                                              Expenses paid
$1,000.00                             Ending value         during period
on 4-30-04                             on 10-31-04        ended 10-31-04 1
- --------------------------------------------------------------------------
Class A                                    $876.30                 $7.55
Class B                                     873.60                 10.83
Class C                                     873.60                 10.83


Together with the value of your account, you may use this information to
estimate the operating expenses that you paid over the period. Simply
divide your account value at October 31, 2004 by $1,000.00, then multiply
it by the "expenses paid" for your share class from the table above. For
example, for an account value of $8,600.00, the operating expenses should
be calculated as follows:

Example

 --                                --      --              --
| My account value  /                |    | "expenses paid"  |      My
|                  / $1,000.00 = 8.6 | X $|                  | =  actual
|    $8,600.00    /                  |    |    from table    |   expenses
 --                                --      --              --

Hypothetical example for comparison purposes

This table allows you to compare your fund's ongoing operating expenses
with those of any other fund. It provides an example of the Fund's
hypothetical account values and hypothetical expenses based on each class's
actual expense ratio and an assumed 5% annual return before expenses (which
is not your fund's actual return). It assumes an account value of $1,000.00
on April 30, 2004, with the same investment held until October 31, 2004.
Look in any other fund shareholder report to find its hypothetical example
and you will be able to compare these expenses.


Account value                                              Expenses paid
$1,000.00                             Ending value         during period
on 4-30-04                             on 10-31-04        ended 10-31-04 1
- --------------------------------------------------------------------------
Class A                                  $1,017.09                 $8.11
Class B                                   1,013.57                 11.64
Class C                                   1,013.57                 11.64

Remember, these examples do not include any transaction costs, such as
sales charges; therefore, these examples will not help you to determine the
relative total costs of owning different funds. If transaction costs were
included, your expenses would have been higher. See the prospectus for
details regarding transaction costs.

1 Expenses are equal to the Fund's annualized expense ratio of 1.60%, 2.30%
  and 2.30% for Class A, Class B, Class C, respectively, multiplied by the
  average account value over the period, multiplied by [number of days in
  most recent fiscal half-year/365 or 366] (to reflect the one-half year
  period).

NOTES TO
STATEMENTS


Note A
Accounting policies

John Hancock Biotechnology Fund (the "Fund") is a non-diversified series of
John Hancock World Fund, an open-end management investment company
registered under the Investment Company Act of 1940. The investment
objective of the Fund is to achieve long-term capital appreciation.

The Trustees have authorized the issuance of multiple classes of shares of
the Fund, designated as Class A, Class B and Class C shares. The shares of
each class represent an interest in the same portfolio of investments of
the Fund and have equal rights as to voting, redemptions, dividends and
liquidation, except that certain expenses, subject to the approval of the
Trustees, may be applied differently to each class of shares in accordance
with current regulations of the Securities and Exchange Commission and the
Internal Revenue Service. Shareholders of a class that bears distribution
and service expenses under the terms of a distribution plan have exclusive
voting rights to that distribution plan.

Significant accounting policies
of the Fund are as follows:

Valuation of investments

Securities in the Fund's portfolio are valued on the basis of market
quotations, valuations provided by independent pricing services or at fair
value as determined in good faith in accordance with procedures approved by
the Trustees. Short-term debt investments maturing within 60 days may be
valued at amortized cost, which approximates market value. Investments in
AIM Cash Investment Trust are valued at their net asset value each business
day.

Joint repurchase agreement

Pursuant to an exemptive order issued by the Securities and Exchange
Commission, the Fund, along with other registered investment companies
having a management contract with John Hancock Advisers, LLC (the
"Adviser"), a wholly owned subsidiary of John Hancock Financial Services,
Inc., may participate in a joint repurchase agreement transaction.
Aggregate cash balances are invested in one or more large repurchase
agreements, whose underlying securities are obligations of the U.S.
government and/or its agencies. The Fund's custodian bank receives delivery
of the underlying securities for the joint account on the Fund's behalf.
The Adviser is responsible for ensuring that the agreement is fully
collateralized at all times.

Investment transactions

Investment transactions are recorded as of the date of purchase, sale or
maturity. Net realized gains and losses on sales of investments are
determined on the identified cost basis.

Class allocations

Income, common expenses and realized and unrealized gains (losses) are
determined at the


20



fund level and allocated daily to each class of shares based on the
appropriate net asset value of the respective classes. Distribution and
service fees, if any, are calculated daily at the class level based on the
appropriate net asset value of each class and the specific expense rate(s)
applicable to each class.

Expenses

The majority of expenses are directly identifiable to an individual fund.
Expenses that are not readily identifiable to a specific fund are allocated
in such a manner as deemed equitable, taking into consideration, among
other things, the nature and type of expense and the relative sizes of the
funds.

Bank borrowings

The Fund is permitted to have bank borrowings for temporary or emergency
purposes, including the meeting of redemption requests that otherwise might
require the untimely disposition of securities. The Fund has entered into a
syndicated line of credit agreement with various banks. This agreement
enables the Fund to participate, with other funds managed by the Adviser,
in an unsecured line of credit with banks, which permits borrowings of up
to $250 million, collectively. Interest is charged to each fund based on
its borrowing. In addition, a commitment fee is charged to each fund based
on the average daily unused portion of the line of credit, and is allocated
among the participating funds. The Fund had no borrowing activity under the
line of credit during the year ended October 31, 2004.

Securities lending

The Fund may lend securities to certain qualified brokers who pay the Fund
negotiated lender fees. The loans are collateralized at all times with cash
or securities with a market value at least equal to the market value of the
securities on loan. As with other extensions of credit, the Fund may bear
the risk of delay of the loaned securities in recovery or even loss of
rights in the collateral, should the borrower of the securities fail
financially. On October 31, 2004, the Fund loaned securities having a
market value of $3,856,536 collateralized by cash in the amount of
$3,935,676. The cash collateral was invested in a short-term instrument.
Securities lending expenses are paid by the Fund to the Adviser.

Federal income taxes

The Fund qualifies as a "regulated investment company" by complying with
the applicable provisions of the Internal Revenue Code and will not be
subject to federal income tax on taxable income that is distributed to
shareholders. Therefore, no federal income tax provision is required. For
federal income tax purposes, the Fund has $4,431,628 of a capital loss
carryforward available, to the extent provided by regulations, to offset
future net realized capital gains. To the extent that such carryforward is
used by the Fund, no capital gain distributions will be made. The loss
carryforward expires as follows: October 31, 2010 -- $3,046,491 and October
31, 2011 -- $1,385,137.

Dividends, interest
and distributions

Dividend income on investment securities is recorded on the ex-dividend
date or, in the case of some foreign securities, on the date thereafter
when the Fund identifies the dividend. Interest income on investment
securities is recorded on the accrual basis. Foreign income may be subject
to foreign withholding taxes, which are accrued as applicable.

The Fund records distributions to shareholders from net investment income
and net realized gains, if any, on the ex-dividend date. Distributions paid
by the Fund with respect to each class of shares are calculated in the same
manner, at the same time and are in the same amount, except for the effect
of expenses that may be applied differently to each class.

As of October 31, 2004, there were no distributable earnings on a tax
basis.

Such distributions and distributable earnings, on a


21



tax basis, are determined in conformity with income tax regulations, which
may differ from accounting principles generally accepted in the United
States of America. Distributions in excess of tax basis earnings and
profits, if any, are reported in the Fund's financial statements as a
return of capital.

Use of estimates

The preparation of these financial statements, in accordance with
accounting principles generally accepted in the United States of America,
incorporates estimates made by management in determining the reported
amount of assets, liabilities, revenues and expenses of the Fund. Actual
results could differ from these estimates.

Note B
Management fee and
transactions with
affiliates and others

The Fund has an investment management contract with the Adviser. Under the
investment management contract, the Fund pays a monthly management fee to
the Adviser equivalent, on an annual basis, to the sum of: (a) 0.90% of the
first $500,000,000 of the Fund's average daily net asset value, (b) 0.85%
of the next $500,000,000 and (c) 0.80% of the Fund's average daily net
asset value in excess of $1,000,000,000.

The Adviser has agreed to limit the Fund's total expenses excluding the
distribution and service fees, to 1.30% of the Fund's average daily net
asset value, on an annual basis, at least until February 28, 2005.
Accordingly, the expense reduction related to the total expense limitation
amounted to $118,517 for the year ended October 31, 2004. The Adviser
reserves the right to terminate this limitation in the future.

The Fund has Distribution Plans with John Hancock Funds, LLC ("JH Funds"),
a wholly owned subsidiary of the Adviser. The Fund has adopted Distribution
Plans with respect to Class A, Class B and Class C, pursuant to Rule 12b-1
under the Investment Company Act of 1940, to reimburse JH Funds for the
services it provides as distributor of shares of the Fund. Accordingly, the
Fund makes monthly payments to JH Funds at an annual rate not to exceed
0.30% of Class A average daily net asset value and 1.00% of Class B and
Class C average daily net asset value. A maximum of 0.25% of such payments
may be service fees, as defined by the Conduct Rules of the National
Association of Securities Dealers. Under the Conduct Rules, curtailment of
a portion of the Fund's 12b-1 payments could occur under certain
circumstances.

Class A shares are assessed up-front sales charges. During the year ended
October 31, 2004, JH Funds received net up-front sales charges of $76,596
with regard to sales of Class A shares. Of this amount, $11,828 was
retained and used for printing prospectuses, advertising, sales literature
and other purposes, $60,031 was paid as sales commissions to unrelated
broker-dealers and $4,737 was paid as sales commissions to sales personnel
of Signator Investors, Inc. ("Signator Investors"), a related
broker-dealer. The Adviser's indirect parent, John Hancock Life Insurance
Company ("JHLICo"), is the indirect sole shareholder of Signator Investors.
Prior to July 15, 2004, Class C shares were assessed up-front sales
charges. During the year ended October 31, 2004, JH Funds received net
up-front sales charges of $6,678 with regard to sales of Class C shares. Of
this amount, $6,487 was paid as sales commissions to unrelated
broker-dealers and $191 was paid as sales commissions to sales personnel of
Signator Investors.

Class B shares that are redeemed within six years of purchase are subject
to a contingent deferred sales charge ("CDSC") at declining rates,
beginning at 5.00% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed.
Class C shares that are redeemed within one year of purchase are subject to
a CDSC at a


22



rate of 1.00% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed.
Proceeds from the CDSCs are paid to JH Funds and are used, in whole or in
part, to defray its expenses for providing distribution-related services
to the Fund in connection with the sale of Class B and Class C shares.
During the year ended October 31, 2004, CDSCs received by JH Funds
amounted to $25,546 for Class B shares and $1,979 for Class C shares.

The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc., ("Signature Services") an indirect subsidiary of JHLICo.
The Fund pays a monthly transfer agent fee at an annual rate of 0.05% of
the Fund's average daily net asset value, plus a fee based on the number of
shareholder accounts and reimbursement for certain out-of-pocket expenses,
aggregated and allocated to each class on the basis of its relative net
asset value. Signature Services agreed to voluntarily reduce the Fund's
asset-based portion of the transfer agent fee if the total transfer agent
fee exceeds the Lipper, Inc. median transfer agency fee for comparable
mutual funds by 0.05%. There were no transfer agent fee reductions during
the year ended October 31, 2004. Signature Services reserves the right to
terminate this limitation at any time.

The Fund has an agreement with the Adviser to perform necessary tax,
accounting and legal services for the Fund. The compensation for the year
amounted to $6,216. The Fund also paid the Adviser the amount of $369 for
certain publishing services, included in the printing fees.

Mr. James A. Shepherdson is a director and/or officer of the Adviser and/or
its affiliates, as well as Trustee of the Fund. The compensation of
unaffiliated Trustees is borne by the Fund. The unaffiliated Trustees may
elect to defer, for tax purposes, their receipt of this compensation under
the John Hancock Group of Funds Deferred Compensation Plan. The Fund makes
investments into other John Hancock funds, as applicable, to cover its
liability for the deferred compensation. Investments to cover the Fund's
deferred compensation liability are recorded on the Fund's books as an
other asset. The deferred compensation liability and the related other
asset are always equal and are marked to market on a periodic basis to
reflect any income earned by the investments, as well as any unrealized
gains or losses. The Deferred Compensation Plan investments had no impact
on the operations of the Fund.

Note D
Investment
transactions

Purchases and proceeds from sales or maturities of securities, other than
short-term securities and obligations of the U.S. government, during the
year ended October 31, 2004, aggregated $17,482,336 and $17,673,959,
respectively.

The cost of investments owned on October 31, 2004, including short-term
investments, for federal income tax purposes, was $22,875,417. Gross
unrealized appreciation and depreciation of investments aggregated
$3,493,712 and $1,490,209, respectively, resulting in net unrealized
appreciation of $2,003,503. The difference between book basis and tax basis
net unrealized appreciation of investments is attributable primarily to the
tax deferral of losses on certain sales of securities.

Note E
Reclassification
of accounts

During the year ended October 31, 2004, the Fund reclassified amounts to
reflect a decrease in accumulated net realized loss on investments of $20,
a decrease in accumulated net investment loss of $429,344 and a decrease in
capital paid-in of $429,364. This represents the amounts necessary to
report these balances on a tax basis, ex clud ing certain temporary
differences, as of October 31, 2004. Additional adjustments may be needed
in subsequent reporting periods. These reclassifications, which have no
impact on the net asset value of the Fund, are primarily attributable to
certain differences in the computation of distributable income and capital
gains under federal tax rules versus accounting principles generally
accepted in the United States of America, and book and tax differences in
accounting for deferred compensation and net operating loss. The
calculation of net investment loss per share in the Fund's Financial
Highlights excludes these adjustments.

Note F
Subsequent event

A special meeting of shareholders was held on December 1, 2004, at which
time one or more new Trustees were elected to the Fund's Board of Trustees.
Several Trustees had reached


24



the age for mandatory retirement and plan to retire in 2004 and 2005. The
Board of Trustees recommended and shareholders approved a proposal to
consolidate the two panels into one Board of Trustees for all open-end
funds within the John Hancock funds complex. The effective date for the
newly elected Trustees to the Fund will be January 1, 2005.

AUDITORS'
REPORT

Report of
Pricewaterhouse-
Coopers LLP,
Independent
Registered Public
Accounting Firm

To the Board of Trustees and Shareholders of
John Hancock Biotechnology Fund,

In our opinion, the accompanying statement of assets and liabilities,
including the schedule of investments, and the related statements of
operations and of changes in net assets and the financial highlights
present fairly, in all material respects, the financial position of John
Hancock Biotechnology Fund (the "Fund") at October 31, 2004, the results of
its operations, the changes in its net assets and the financial highlights
for the periods indicated, in conformity with accounting principles
generally accepted in the United States of America. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these financial statements in
accordance with the standards of the Public Company Accounting Oversight
Board (United States). Those standards require that we plan and perform the
audits to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining,
on a test basis, evidence supporting the amounts and disclosures in the
financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which
included confirmation of securities at October 31, 2004 by correspondence
with the custodian and brokers, provide a reasonable basis for our opinion.

ITEM 2.  CODE OF ETHICS.

As of the end of the period, October 31, 2004, the registrant has adopted a
code of ethics, as defined in Item 2 of Form N-CSR, that applies to its
Chief Executive Officer, Chief Financial Officer and Treasurer
(respectively, the principal executive officer, the principal financial
officer and the principal accounting officer, the "Senior Financial
Officers"). A copy of the code of ethics is filed as an exhibit to this
Form N-CSR.

ITEM 3.  AUDIT COMMITTEE FINANCIAL EXPERT.

William F. Glavin is the audit committee financial expert and is
"independent", pursuant to general instructions on Form N-CSR Item 3.

ITEM 4.  PRINCIPAL ACCOUNTANT FEES AND SERVICES.

(a) Audit Fees

The aggregate fees billed for professional services rendered by the
principal accountant(s) for the audit of the registrant's annual financial
statements or services that are normally provided by the accountant(s) in
connection with statutory and regulatory filings or engagements amounted to
$45,200 for the fiscal year ended October 31, 2003 (broken out as follows:
John Hancock Biotechnology Fund - $17,000 and John Hancock Health Sciences
Fund - $28,200)  and $47,500 for the fiscal year ended October 31, 2004
(broken out as follows: John Hancock Biotechnology Fund - $17,850 and John
Hancock Health Sciences Fund - $29,650). These fees were billed to the
registrant and were approved by the registrant's audit committee.

(b) Audit-Related Services

There were no audit-related fees during the fiscal year ended October 31,
2003 and fiscal year ended October 31, 2004 billed to the registrant or to
the registrant's investment adviser (not including any sub-adviser whose
role is primarily portfolio management and is subcontracted with or
overseen by another investment adviser), and any entity controlling,
controlled by, or under common control with the adviser that provides
ongoing services to the registrant ("control affiliates").

(c) Tax Fees

The aggregate fees billed for professional services rendered by the
principal accountant(s) for the tax compliance, tax advice and tax planning
("tax fees") amounted to $6,000 for the fiscal year ended October 31, 2003
(broken out as follows: John Hancock Biotechnology Fund - $3,000 and John
Hancock Health Sciences Fund - $3,000) and $6,300 for the fiscal year ended
October 31, 2004 (broken out as follows: John Hancock Biotechnology Fund -
$3,150 and John Hancock Health Sciences Fund - $3,150). The nature of the
services comprising the tax fees was the review of the registrant's income
tax returns and tax distribution requirements. These fees were billed to
the registrant and were approved by the registrant's audit committee. There
were no tax fees billed to the control affiliates.

(d) All Other Fees

There were no other fees during the fiscal year ended October 31, 2003 and
fiscal year ended October 31, 2004 billed to the registrant or to the
control affiliates.

(e)(1) See attachment "Approval of Audit, Audit-related, Tax and Other
Services", with the audit committee pre-approval policies and procedures.

(e)(2) There were no fees that were approved by the audit committee
pursuant to the de minimis exception for the fiscal years ended October 31,
2003 and October 31, 2004 on behalf of the registrant or on behalf of the
control affiliates that relate directly to the operations and financial
reporting of the registrant.

(f) According to the registrant's principal accountant, for the fiscal year
ended October 31, 2004, the percentage of hours spent on the audit of the
registrant's financial statements for the most recent fiscal year that were
attributed to work performed by persons who were not full-time, permanent
employees of principal accountant was less than 50%.

(g) The aggregate non-audit fees billed by the registrant's accountant(s)
for services rendered to the registrant and rendered to the registrant's
control affiliates for each of the last two fiscal years of the registrant
were $6,000 for the fiscal year ended October 31, 2003 and $62,762 for the
fiscal year ended October 31, 2004.

(h) The audit committee of the registrant has considered the non-audit
services provided by the registrant's principal accountant(s) to the
control affiliates and has determined that the services that were not
pre-approved are compatible with maintaining the principal accountant(s)'
independence.
