DEAR FELLOW SHAREHOLDERS:

During the last  decade,  investors  have  become  used to seeing  stock  market
returns averaging 15% or so each year. In the past three years, the stock market
has treated us to a record run, producing annual returns in excess of 20%. 

After such a long and  remarkable  performance,  many began this year  wondering
what the market would do for an encore in 1998.  The answer so far has been more
of the same, even with the recent increase in volatility  caused by tremors from
Asia. This achievement continues to bolster many investors' convictions that the
market will produce these results  forever,  or, in the worst case,  that market
declines  will always be  short-lived.  While the economy  remains solid and the
environment  favorable,  history  and  reason  tell  us it's a  highly  unlikely
scenario.

This doesn't mean we know what the market will do next,  or that it's riding for
a fall. But after such a run, even in this "new era" of strong  economic  growth
with low  inflation,  we  believe  it would  be wise for  investors  to set more
realistic  expectations.  As we've said  before,  markets do indeed  move in two
directions.  Over the long term, the market's  historical results have been more
in the 10% per year range,  which is still a solid  result,  considering  it has
been produced  despite wars,  depressions  and other social  upheavals along the
way.

- --------------------------------------------------------------------------------

Officer, flush right, next to third paragraph.]
- --------------------------------------------------------------------------------

In addition to adjusting, or at least re-examining, expectations, now could also
be a good time to review with your investment  professional  how your assets are
diversified,  perhaps with an eye toward a more conservative  approach.  Stocks,
especially  with their outsized gains of the last three years,  might have grown
to represent a larger piece of your portfolio than you had originally  intended,
given your objectives, time horizon and risk level.

At John Hancock Funds,  our goal is to help you reach your financial  objectives
and maintain wealth.  One way we can do that is by helping you keep your feet on
the ground as you pursue your dreams.

Sincerely,

/s/Edward J. Boudreau, Jr.

                                  John Hancock
                              Sovereign Bond Fund

                   Bond market, despite turbulence, produces
                     double-digit gains over last 12 months

Market  turbulence  greeted  the Fund at the outset of the fiscal  year with the
devaluation of the Thai baht in July of 1997.  Inflation fears then got the best
of many  investors in August,  resulting in declining  U.S.  bond prices.  While
Asia's  currency woes  continued to quietly build steam in the following  weeks,
domestic  bond markets  shook off the yoke of nagging  concern and resumed their
uphill charge.

By late October and early  November,  the fiscal ills  plaguing the Asian region
spilled over into world markets, causing U.S. investment-grade  corporate bonds,
high-yield debt and emerging-market  issues to come under considerable pressure.
Worldwide, investors flocked to the relative safety of U.S. Treasury securities.
As a result,  U.S.  corporate  bonds N both  high-yield and  investment-grade  N
underperformed  U.S.  Treasury  bonds during this period.  Emerging-market  debt
across the globe  suffered the most,  plunging in either direct  response to the
spreading Asian crisis or in general sympathy with the Far East markets.

Relative   stability   returned   quickly   to   the   U.S.   market,   although
investment-grade  corporate  bonds and  high-yield  issues have yet to keep pace
with soaring Treasury bond prices. In fact, the yield on the bellwether  30-year
bond has traded within a historically low range of approximately  5.69% to 6.14%
since December. Emerging markets, however, have

"...opportun-istically selling most of our Asian positions..."

remained  unsettled since.  Bouts of volatility have continued across Asia, with
the rioting in Indonesia  the most recent  event to impact the markets.

Against  this  fitful  backdrop,  John  Hancock  Sovereign  Bond  Fund  rewarded
investors  with a 12-month gain of 10.54% for Class A shares and 9.78% for Class
B shares at net asset value.  Keep in mind that your net asset value return will
be different from this  performance if you were not invested in the Fund for the
entire period and did not reinvest all distributions. The Fund's performance was
in line with that of the average  corporate debt A-rated fund,  which produced a
gain of 10.85% at net asset  value,  according  to Lipper  Analytical  Services,
Inc.1 Please see pages six and seven for longer-term performance information.

Emerging market exposure  trimmed 

A calm,  well-researched  approach  to  investing  in emerging
markets has helped the Fund  weather this  sector's  turbulence  throughout  the
period.  Knowing when to invest and what credits to buy,  sell and avoid has not
been a matter of chance.  We have gone to great  lengths to fortify our research
staff,   employing  not  only  credit  analysts - researchers  who  scrutinize
individual companies N but also a sovereign credit analyst who examines both the
creditworthiness  of  individual  governments  and the  economic  and  political
landscapes of various  regions.  Although the Fund was not immune to the effects
of the Asian  currency  debacle,  we were able to avoid  much of the  carnage by
opportunistically  selling  most  of  our  Asian  positions  late  last  summer.

Furthermore,  by carefully  adjusting our allocations,  we were able to sidestep
troubled  debt.  For example,  when several  Japanese banks came to market a few
months ago issuing


"...media, telecommunications and utilities... were dominant sectors..."

attractively priced,  high-yielding  securities that carried an investment-grade
rating, many fund managers, including ourselves, found the issues too compelling
to ignore. However, we soon determined that the risk was not worth the potential
reward  and sold our stake - a timely  maneuver  since the  bonds  have  dropped
considerably  in price  since.  To date,  we have  continued to avoid most Asian
debt,  believing the investment  environment remains murky. Our small investment
in Latin  American  bonds  has come  under  pressure  recently  along  with most
emerging market debt;  however, we believe the securities are well positioned to
fully  recover.   

Corporate  bond   diversification  

The  Fund  remains  broadly
diversified across American industry in the corporate bond arena - the sector of
the market that generally  accounts for the bulk of the Fund's assets.  Holdings
in media,  telecommunications  and utilities,  however, were dominant sectors at
the  period's  end.   Merger  and   acquisition   activity,   deregulation   and
consolidation have been the ongoing catalysts of change and opportunity in these
industries.  The relative  underperformance  of high-yield and  investment-grade

corporate  bonds in the  latter  half of the  fiscal  year  allowed us to add to
existing  positions  and  purchase new holdings at  attractive  prices.  Notable
performers  in  these  categories  included  telecommunications   companies  TCI
Communications and Nextel Communications; utilities Long Island Lighting Co. and
Cleveland  Electric  Illuminating Co. and media companies Time Warner,  Adelphia
Communications  and News America  Holdings.  

Duration and yield curve strategies

While duration and yield curve  strategies  are not our primary  focus,  we will
capitalize on opportunities as they present  themselves.  For most of the fiscal
year,  the Fund's  average  duration - a measure  of the Fund's  sensitivity  to
interest  rate  changes -  remained  relatively  neutral  in  comparison  to its
benchmark.  In the  period's  first  half,  we  aligned  the  Fund's  government
securities at opposite ends of the yield curve, owning both short- and long-term
securities.  This  structure,  known as a "barbell,"  helped optimize the Fund's
total return potential as the difference in short- and long-term  interest rates
narrowed  and the yield curve  flattened.  In the second half of the period,  we
took steps to position for the  possibility  that the yield curve might steepen,
redeploying  assets in  intermediate-term  securities  at the middle part of the
curve.  This  "bullet"  strategy  historically  works  well when the  difference
between the interest  rates of short- and long-term  securities  widens.  Such a
move may have been a bit  premature in  hindsight,  since the curve has remained
flat;  however,  we believe it will best serve the Fund  should the yield  curve
steepen as we anticipate in the months ahead. 

More challenges ahead 

As we enter fiscal 1999, the Fund is somewhat  defensively  positioned,  with an
emphasis on corporate  sectors that stand to perform well regardless of economic
swings. We believe at some point down the road there may be


"...the Fund is somewhat defensively positioned..."

opportunities  to capture  some  value in  emerging-market  issues,  but for now
extreme  caution is the  watchword.  The crisis in Asia is just now  starting to
take a bit of steam out of the robust U.S.  economy,  although whether it serves
to stave off  inflation  remains to be seen.  How this  situation  affects  U.S.
corporations  bears close monitoring.  Whatever occurs,  selectivity in terms of
credit  quality and price will remain our focus.  

This commentary  reflects the views of the portfolio  manager through the end of
the Fund's period discussed in this report.  Of course,  the manager's views are
subject to change as market and other conditions warrant.

A LOOK AT PERFORMANCE

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock  Sovereign Bond Fund.  Total return  measures
the change in value of an investment  from the beginning to the end of a period,
assuming all distributions were reinvested.

For Class A shares,  total return  figures  include a maximum  applicable  sales
charge of 4.5%. Class B performance reflects a maximum contingent deferred sales
charge (maximum 5% and declining to 0% over six years).

All figures  represent past  performance and are no guarantee of future
results.  Keep in mind  that the total  return  and  share  price of the  Fund's
investments will fluctuate. As a result, your Fund's shares may be worth more or
less than their original cost, depending on when you sell them. Please read your
prospectus  carefully  before you invest or send  money.

                         NOTES TO FINANCIAL STATEMETNTS

                    John Hancock Funds - Sovereign Bond Fund

NOTE A -
ACCOUNTING POLICIES

John  Hancock  Sovereign  Bond  Fund  (the  "Fund")  is a  diversified  open-end
investment  management  company,  registered under the Investment Company Act of
1940.  The  investment  objective  of the Fund is to  generate  a high  level of
current income, consistent with prudent investment risk, through investment in a
diversified  portfolio of freely  marketable debt securities.  

The  Trustees  have  authorized  the  issuance of multiple  classes of the Fund,
designated  as Class A and  Class B.  The  shares  of each  class  represent  an
interest in the same  portfolio of investments of the Fund and have equal rights
to voting, redemption,  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
which bears  distribution and service expenses under the terms of a distribution
plan, have exclusive voting rights regarding such 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 are valued at amortized cost
which approximates market value.

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,  Inc.  (the  "Adviser"),  a wholly owned
subsidiary of The Berkeley  Financial  Group,  Inc., may  participate in a joint
repurchase agreement transaction. Aggregate cash balances are invested in one or
more 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.

FEDERAL  INCOME TAXES 

The Fund's  policy is to comply with the  requirements  of the Internal  Revenue
Code that are applicable to regulated investment companies and to distribute all
of its taxable  income,  including any net realized gain on  investment,  to its
shareholders.  Therefore,  no federal  income tax  provision  is  required.  For
federal  income  tax  purposes,   the  Fund  has  $22,827,929  of  capital  loss
carryforwards available, to the extent provided by regulations, to offset future
net realized  capital gains. To the extent that such  carryforwards  are used by
the Fund, no capital gain distributions  will be made. The carryforwards  expire
as follows: May 31, 2001 N $3,894,200, May 31, 2002 N $9,347,493, May 31, 2004 N
$8,402,805 and May 31, 2005 N $1,183,431. Expired capital loss carryforwards are
reclassified to capital paid-in in the year of expiration.

DIVIDENDS,  DISTRIBUTIONS AND INTEREST Interest  income on investment securities
is  recorded  on the  accrual  basis.  

The Fund records all  distributions to shareholders  from net investment  income
and  net  realized  gains  on  the  ex-dividend  date.  Such  distributions  are
determined  in  conformity  with income tax  regulations,  which may differ from
generally  accepted  accounting  principles.  Dividends  paid by the  Fund  with
respect to each class of shares will be  calculated  in the same manner,  at the
same time and will be in the same amount, except for the effect of expenses that
may be applied differently to each class.

DISCOUNT ON  SECURITIES The  Fund accretes discount from par value on securities
from  either  the date of issue  or the  date of  purchase  over the life of the
security,  as required by the Internal Revenue Code.  






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

                         NOTES TO FINANCIALS STATEMENTS

                    John Hancock Funds - Sovereign Bond Fund

USE OF ESTIMATES 

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

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. These agreements enable the Fund
to  participate  with other funds  managed by the Adviser in unsecured  lines of
credit with banks which  permit  borrowings  up to $800  million,  collectively.
Interest  is charged to each fund,  based on its  borrowing,  at a rate equal to
0.50% over the Fed Funds Rate. In addition,  a commitment  fee, at rates ranging
from 0.070% to 0.075% per annum based on the average daily unused portion of the
line of credit,  is allocated  among the  participating  funds.  The Fund had no
borrowing activity for the year ended May 31, 1998.

FINANCIAL FUTURES CONTRACTS 

The Fund may buy and sell  financial  futures  contracts  to hedge  against  the
effects of  fluctuations in interest rates and other market  conditions.  Buying
futures  tends to increase  the Fund's  exposure to the  underlying  instrument.
Selling  futures  tends  to  decrease  the  Fund's  exposure  to the  underlying
instrument or hedge other Fund  instruments.  At the time the Fund enters into a
financial futures contract,  it will be required to deposit with its custodian a
specified  amount  of cash or U.S.  government  securities,  known  as  "initial
margin,"  equal to a certain  percentage of the value of the  financial  futures
contracts being traded. Each day, the futures contract is valued at the official
settlement price of the board of trade or U.S.  commodities exchange on which it
trades. Subsequent payments, known as "variation margin," to and from the broker
are made on a daily basis as the market price of the financial  futures contract
fluctuates.  Daily  variation  margin  adjustments,  arising  from this "mark to
market," are recorded by the Fund as unrealized gains or losses.


When the  contracts  are closed,  the Fund  recognizes a gain or loss.  Risks of
entering into futures  contracts  include the  possibility  that there may be an
illiquid  market  and/or  that a change  in the  value of the  contract  may not
correlate with changes in the value of the underlying  securities.  In addition,
the Fund could be prevented  from  opening or realizing  the benefits of closing
out  futures  positions  because  of  position  limits or limits on daily  price
fluctuations  imposed by an  exchange.  

For federal income tax purposes, the amount,  character and timing of the Fund's
gains and/or losses can be affected as a result of futures transactions.

At May 31, 1998, there were no open positions in financial futures contracts.

NOTE  B-  MANAGEMENT  FEE  AND
TRANSACTIONS WITH AFFILIATES AND OTHERS 

Under the present investment management contract, the Fund pays a monthly fee to
the Adviser for a continuous investment program equivalent on an annual basis to
the sum of (a) 0.50% of the first $1,500,000,000 of the Fund's average daily net
asset  value,  (b)  0.45%  of the  next  $500,000,000,  (c)  0.40%  of the  next
$500,000,000 and (d) 0.35% of the Fund's average daily net asset value in excess
of $2,500,000,000.

The Fund has a  distribution  agreement  with  John  Hancock  Funds,  Inc.  ("JH
Funds"),  a wholly owned  subsidiary of the Adviser.  For the year ended May 31,
1998, JH Funds received net sales charges of $1,444,580  with regard to sales of
Class A shares. Out of this amount,  $164,116 was retained and used for printing
of prospectuses,  advertising, sales literature and other purposes, $372,323 was
paid as sales commissions to unrelated  broker-dealers  and $908,141 was paid as
sales  commissions  to  sales  personnel  of  John  Hancock  Distributors,  Inc.
("Distributors"),  a related broker-dealer.  The Adviser's indirect parent, John
Hancock  Mutual  Life  Insurance  Company  ("JHMLICo"),  is  the  indirect  sole
shareholder of Distributors.

Class B shares which are redeemed  within six years of purchase  will be 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.  Proceeds from the CDSC are
paid to JH Funds and are used in whole or

                                       25
<PAGE>

in part to  defray  its  expenses  related  to  providing  distribution  related
services to the Fund in connection with the sale of Class B shares. For the year
ended May 31,  1998,  contingent  deferred  sales  charges  received by JH Funds
amounted to  $359,205.  

In addition,  to reimburse JH Funds for the services it provides as  distributor
of shares of the Fund, the Fund has adopted  Distribution  Plans with respect to
Class A and Class B pursuant to Rule 12b-1 under the  Investment  Company Act of
1940. Accordingly,  the Fund will make payments to JH Funds for distribution and
service  expenses at an annual rate not to exceed 0.30% of Class A average daily
net assets and 1.00% of Class B average daily net assets,  to reimburse JH Funds
for its  distribution  and  service  costs.  Up to a  maximum  of 0.25% of these
payments may be service fees as defined by the amended Rules of Fair Practice of
the National Association of Securities Dealers.  Under the amended Rules of Fair
Practice curtailment of a portion of the Fund's 12b-1 payments could occur under
certain circumstances.

The Fund has a transfer agent  agreement with John Hancock  Signature  Services,
Inc.  ("Signature  Services"),  an indirect subsidiary of JHMLICo. The Fund pays
transfer  agent fees based on the number of  shareholder  accounts  and  certain
out-of-pocket expenses.

The  Fund has an  agreement  with  the  Adviser  to  perform  necessary  tax and
financial management services for the Fund. The compensation for the year was at
an annual rate of less than 0.02% of the average net assets of the Fund.

Mr. Edward J. Boudreau, Jr., Ms. Anne C. Hodsdon and Mr. Richard S. Scipione are
trustees  and/or  officers of the  Adviser,  and/or its  affiliates,  as well as
Trustees 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 investment as well as any  unrealized  gains or
losses.   At  May  31,  1998,  the  Fund's  investment  to  cover  the  deferred
compensation had unrealized appreciation of $11,737.

NOTE C- INVESTMENT  TRANSACTIONS 

Purchases  and proceeds  from sales and  maturities  of  securities,  other than
obligations of the U.S.  Government and its agencies and short-term  securities,
during   the  year   ended  May  31,   1998,   aggregated   $1,096,959,509   and
$1,187,726,604,  respectively.  Purchases and proceeds from sales of obligations
of the U.S.  government  and its  agencies,  during the year ended May 31, 1998,
aggregated $1,724,339,434 and $1,640,718,324, respectively.

The cost of  investments  owned at May 31,  1998
(including the joint  repurchase  agreement) for federal income tax purposes was
$1,495,035,201.  Gross  unrealized  appreciation and depreciation of investments
aggregated   $45,606,006  and  $17,586,978,   respectively,   resulting  in  net
unrealized  appreciation of $28,019,028.  

NOTE D- 

Reclassification  of accounts  During the year ended May 31, 1998,  the Fund has
reclassified  amounts to reflect an increase in accumulated net realized loss on
investments  of  $14,036,842,  an  increase  in  distributions  in excess of net
investment income of $303,523 and an increase in capital paid-in of $14,340,365.
This  represents  the amount  necessary to report these balances on a tax basis,
excluding  certain  temporary  differences,  as  of  May  31,  1998.  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 generally
accepted  accounting  principles.  The calculation of net investment  income per
share in the financial highlights excludes these adjustments.

REPORT OF ERNST & YOUNG LLP,  INDEPENDENT  AUDITORS 
To the Board of Trustees and Shareholders of 
John Hancock Sovereign Bond Fund

We have audited the accompanying statement of assets and liabilities of the John
Hancock Sovereign Bond Fund (the "Fund"), including the schedule of investments,
as of May 31, 1998,  and the related  statement of operations  for the year then
ended,  and the statement of changes in net assets and the financial  highlights
for each of the  periods  indicated  therein.  These  financial  statements  and
financial  highlights  are the  responsibility  of the  Fund's  management.  Our
responsibility  is to  express  an opinion  on these  financial  statements  and
financial  highlights based on our audits. 

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  Our procedures included  confirmation of securities owned as of May
31, 1998, by correspondence with the custodian and brokers, or other appropriate
auditing procedures where replies from brokers were not received.  An audit also
includes assessing the accounting principles used and significant estimates made
by  management,   as  well  as  evaluating  the  overall   financial   statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

In our opinion,  the financial  statements and financial  highlights referred to
above present fairly, in all material  respects,  the financial  position of the
John Hancock  Sovereign Bond Fund at May 31, 1998, the results of its operations
for the year then  ended,  and the  changes in its net assets and the  financial
highlights  for each of the  indicated  periods,  in conformity  with  generally
accepted accounting principles.
