內 容 提 要

形容詞和副詞在語法結構中主要用于比較級和最高級。形容詞和副詞的構成形式基本上一樣，它們的形式與單音節、雙音節和多音節有關，當然還有其特殊形式。形容詞和副詞比較級的基本用法分為同級比較、比較級和最高級三種形式。但這三種形式都有它們特殊的表達方式以及它們的慣用法。對以下要點大家須一一掌握。

I形容詞比較級和最高級的形式

一、形容詞比較級和最高級的構成

形容詞的比較級和最高級變化形式規則如下

構 成 法 原 級 比 較 級 最 高 級

① 一般單音節詞末尾加瞖r 和 瞖st strong stronger strongest

② 單音節詞如果以瞖結尾，只加瞨 和瞫t strange stranger strangest

③ 閉音節單音節詞如末尾只有 一個輔音字母，

須先雙寫這個輔音字母，再加瞖r和瞖st sad

big

hot sadder

bigger

hotter saddest

biggest

hottest

④ 少數以瞴,瞖r(或瞮re),瞣w,瞓le結尾的雙音節詞， 末尾加瞖r和瞖st(以瞴結尾的詞，如瞴前是輔音字母， 把y變成i，再加瞖r和瞖st，以瞖結尾的詞仍加瞨和瞫t) angry

clever

narrow

noble angrier

cleverer

narrower

nobler angrest

cleverest

narrowest

noblest

⑤ 其他雙音節和多音節詞都在前面加單詞more和most different more

different most

different

1) The most high ［A］ mountain in ［B］ the world is Mount Everest， which is situated ［C］ in Nepal and is twenty瞡ine thousand one hundred and fourty one feet high ［D］ .

2) This house is spaciouser ［A］ than that ［B］ white ［C］ one I bought in Rapid City， South Dakota ［D］ last year.

3) Research in the social ［A］ sciences often proves difficulter ［B］ than similar ［C］ work in the physical ［D］ sciences.

二、形容詞比較級或最高級的特殊形式：

1. 三個或三個以上音節的形容詞只能加more和most

只能說 more beautiful而不能說beautifuller; 只能說the most beautiful而不能說beautifullest。

但是，以形容前綴瞮n結尾的三音節形容詞不適合上述情況，如unhappy,untidy，我們可以說：unhappier→unhappiest, untidier→untidiest

2. 由睮NG分詞和睧D分詞演變過來的形容詞(包括不規則動詞如know→known)只能加more或most來表示它們的比較級和最高級

more(most) striking, more(most) interesting, more(most) wounded, more(most)worn等。

4) The drawings ［A］ of the old masters ［B］ are among the treasuredest ［C］ works in museums ［D］ .

3. 英語里有些形容詞由于其詞義而不可能有比較級形式

absolute fatal main right universal

chief final naked simulta- utter

entire foremost perfect neous vital

eternal inevitable possible sufficient whole

excellent infinite primary supreme wooden

三、不規則形容詞的比較級和最高級形式

good well better best

bad ill worse worst

many much more most

little few less least

far farther farthest

further furthest

5) African elephants are larger， fiercer， and difficulter ［A］ to tame ［B］ than ［C］ Asian elephants ［D］ .

6) Sarah Hale became ［A］ one of the famousest ［B］ magazine ［C］ editors in the United States during ［D］ the 1800’s.

7) Of all ［A］ the Native American tribes ［B］ ， the Shawnee Indians were ［C］ a most ［D］ transient.

四、例題解析

1) A錯。應將“most high”改為highest。這是在考形容詞比較級的構成形式。

2) A錯。改為more spacious。

3) B錯。 改為more difficult。

4) C錯。 treasured 在本句中是睧D分詞(動詞treasure ＋ed)作形容詞使用，是“寶貴的、珍貴的”意思，修飾名詞 works(作品)，其最高級形式應用 the most treasured。

5) A錯，改為more difficult。

6) B錯。改為“the most famous”，因為famous(著名的)是雙音節，其最高級變化應在前面加“the most”。

7) D錯。應改為“the most”，因為此處表示的是最高級，“the most transient”意為“(延續時間)最短暫的”。

II 副詞比較級和最高級的形式

副詞比較級和最高級的變化形式與形容詞基本上一樣

一般 副詞

hard→harder →hardest

fast→faster →fastest

late→later →latest

early→earlier →earliest

特殊 副詞

well →better →best

much →more →most

badly →worse →worst

little →less →least

但是，開放類副詞即以后綴瞝y結尾的副詞不能像形容詞那樣加瞖r或瞖st，如

quickly →more quickly →most quickly quietly →more quietly →most quietly

［注］： early中的瞝y不是后綴，故可以把瞴變瞚再加瞖r和瞖st

III形容詞與副詞比較級和最高級的基本用法

一、原級比較的基本用法

1. 原級比較由“as＋形容詞或副詞(或再加名詞或短語)＋as ”構成“原級相同”比較句，表示兩者比較；其否定式，即“程度不及”比較句型為“not so(as) ＋形容詞或副詞＋as”，而且as…as結構前可用just, almost, nearly, quite等表示程度的詞修飾

1) Walking briskly for thirty minutes will burn as many calories as .

［A］ to run for fifteen minutes

［B］ running for fifteen minutes

［C］ you run for fifteen minutes

［D］ fifteen瞞inute walking

2) The gorilla(大猩猩)， while ［A］ not quite as curious than ［B］ the chimpanzee(黑猩猩)， shows more persistence ［C］ and memory retention(記憶力) in solving ［D］ a problem.

3) Alaska is twice ［A］ as larger ［B］ as ［C］ the next largest ［D］ state， Texas.

2. “as (so)＋名詞＋as＋名詞”進行名詞比較，這時一般情況下有一個表示原級的比較詞，但如果第一名詞前出現了形容詞修飾該詞或出現副詞修飾謂語，應當用so而不用as

4) Thomas Jefferson’s achievements as an architect rival his contributions a politician.

［A］ such

［B］ more

［C］ as

［D］ than

5) I should say Henry is not much a writer as a reporter. (88年考題)

［A］ that

［B］ so

［C］ this

［D］ as

二、比較級

1. 比較級由“形容詞(副詞)比較級＋than＋…，”構成表示在兩者中間一方比另一方“更加…”。連詞than后可接句子，也可接名詞、代詞、名詞短語、介詞短語、動詞、動詞不定式、睮NG結構和睧D結構，有時也可省去than。

6) Natural mica(云母) of ［A］ a superior ［B］ quality is cheapest ［C］ to obtain than synthetic ［D］ mica.

7) She is older than .

［A］ any other girl in the group

［B］ any girl in the group

［C］ all girls in the group

［D］ you and me as well as the group

8) Josephine McCrackin joined ［A］ the “Santa Cruz Sentinel” in 1905 and， until her death fifteen years late ［B］ ， remained ［C］ active in journalistic ［D］ work.

2. 注意than前后兩項相比較的人或事物要一致

9) The purpose of the research had a more important meaning for them than .

［B］ with us

［C］ for ours it had

［D］ it did for us

10) Sound travels air.

［B］ faster than through water and

［C］ through water faster and

［D］ where it is faster through water than through

11) Gerbrand von den Feckhout， one of Rembrand’s pupils， followed ［A］ the style of his teacher so implicitly that ［B］ his paintings ［C］ are sometimes confused with his master ［D］ .

三、最高級

1. 最高級用于三者以上比較，形容詞的結構形式是“定冠詞＋形容詞最高級＋名詞＋表示范圍的短語或從句”(如all, of all, of the tree, in the world, that has ever taken place等)

12) The more ［A］ fearsome of all the ［B］ animals in ［C］ the Western ［D］ Hemisphere is the grizzly bear.

13) Of all economic ［A］ problems， inflation continues to be ［B］ a ［C］ most significant in its daily impact on ［D］ people and business.

14) ， the most familiar to general public is the criminal jurisdiction.

［A］ All the activities

［B］ The activities

［C］ Of all the activities

［D］ It is the activities

2. 副詞的最高級與形容詞最高級的區別在于最高級前沒有定冠詞the

四、例題解析

1) B為正確答案。

2) B錯。改為 as ，和前面的as和形容詞原形curious 一起構成同程度比較。

3) B錯。 改為as large。

4) C對。動詞rival(勝過、匹敵)前后是兩個相比較的成分achievements(成果)和 contributions(貢獻)，由于前面的名詞后出現了短語 as an architect，故空白處也應用as，使前后對比成分一致。

5) B為正確答案。

6) C錯。應改為比較級cheaper。比較級后并不一定跟接連詞than，有時在其間有名詞或名詞短語(被形容詞所修飾)，介詞短語，不定式或其他成分隔開。

7) A為正確答案�！癝he”作為單個不能跟全組比(C和D不對)，也不能跟全組所有相比，因為“她”也是其中一員，自然“她”不能跟自己相比。這里“She”比較的是“這組中的任何一個”，所以A對。

8) B錯。應改為比較級later，因此處實為與1905年相比晚15年，故應使用比較級。

9) D為正確答案。

10) A為正確答案。

11) D錯。 改為his master’s。

12) A錯。 改為most。

13) C錯。改為the， significant是多音節形容詞，在此處應用最高級形式(在前面加 the most)，注意句中的“of all… ”。

14) C為正確答案。本句空白處缺狀語，A和B全為名詞短語，不符合條件；D為句子，和空白后面的句子沒有任何聯系，故亦應排除。只有C正確，和后面的最高級the most familiar前后呼應。

IV 形容詞和副詞的特殊表達法

一、形容詞與副詞的同級比較： 由“as(so)…as”引出，其否定式為“not so…”或“not as…as”,考生還應注意下列含有“as”結構或短語的句子

［A］ than inventing

［B］ than as the inventor

［C］ the invention

［D］ as the inventor

十、most表示“非常”： 有時most并不表示“最……”，而是作副詞表示“非常”之意。其實它是much的最高級，作形容詞用是“大多數”之意，前邊不加the。另外much與to構成介詞詞組，表示“在很大程度上使……”that也可以作副詞用，表示“如此，那么”相當于so

28) During ［A］ the seventeenth century the most ［B］ colonists were primarily concerned with ［C］ D)] economics ［D］ and defense.

十一、形容詞與副詞的修飾關系： 一般來說，形容詞用來作表語(與系動詞連用，注意taste, feel, become等詞作系動詞用時，它們后的表示應該是形容詞，包括瞖d分詞)或作定語修飾名詞，而形容詞不能修飾形容詞包括睧D分詞；但副詞可以修飾形容詞(包括睧D分詞)，副詞還可以修飾副詞、動詞或短語

29) Belgium, in the ［A］ 19th century, rapid ［B］ grew into ［C］ an industrial ［D］ country.

30) The Lost Colony in North Carolina mysterious ［A］ disappeared between ［B］ 1587 and 1590, when its ［C］ founder returned from a visit ［D］ to England.

十二、形容詞與副詞的位置

1. 當幾個形容詞共同修飾同一名詞時，它們的先后順序是：限定詞→數詞→描述性形容詞→大小、長短、形狀的形容詞→色彩形容詞→類屬形容詞→表材料形容詞+被修飾的名詞；或只記住限定詞像a, the, my, their等詞在最前邊，其他詞根據它們與被修飾名詞關系的遠近進行安排

31) Many flatworms have of eyes.

［A］ more pairs than one

［B］ more than one pair

［C］ one more pair than

［D］ one pair more than

good enough, mysterious enough

3. so修飾的是副詞，而such修飾的是名詞

34) The radio was of so ［A］ inferior quality that ［B］ I took it back ［C］ and asked for a better one ［D］ .

3. 形容詞修飾名詞時放在前邊，但修飾復合不定代詞(something, someone, somebody; anything, anyone, anybody; nothing, no瞣ne, nobody)時，則放在這些詞之后

something important, anything possible

十三、關于hardly, rarely, scarcely與seldom的用法

hardly“剛剛，不完全”，表示程度：I hardly know him. “我幾乎認不出他了”，表示還是能認出或者說“我剛剛能認出他”；hardly與any連用表示“幾乎沒有”，與ever連用表示“幾乎從來不”； scarcely的意思與hardly更接近。rarely“不經�！�，表示事物發生的頻率：He rarely goes there. 他很少(不經常)去那里。seldom“很少，不經�！�，它與rarely更接近。

十四、例題解析

1) D錯。 改為than。

2) B對。本句的漢語意思是“照相機的鏡頭和眼睛的水晶體所起的作用相同”。

3) B對。本句的漢語意思是“消除通貨膨漲會保證還的錢與借時的錢同值”。

4) B為正確答案。

5) C為正確答案。

8) C為正確答案。

9) D為正確答案。

10) D為正確答案。

11) B錯。 改為worse。

12) C錯。 改為less。

13) D對。本句中的比較級為形容詞more (much 的比較級)，被比較的兩個事物為“hot objects”和“cold objects”，在所釋放(emit)的紅外線(infrared rays)的量上，前者多于后者。其中more修飾infrared rays，它們不能被分開，故只有D在詞序上正確�？瞻缀竺鏋榈寡b語序，其中的do代替動詞emit，本句空白后也可用正常語序，即“cold objects do”。

14) B錯。 改為than。

15) D錯。 改為that，代替population。

16) D錯。 改為that。這里比較的“The grain”不是復數，不能用復數代詞those。

17) C為正確答案。比較句中，連詞than前后，即所比較的成分要一致，應該在同種事物間進行比較。本句所比較的是兩種 activities ，故C正確，代詞those 代替“the activities”。

18) A對。“one of the oldest…”表示“(歷史)最長的栽種植物之一”，C和D均不合語法，而B選項中的one多余。

19) D為正確答案。

20) A為正確答案。

21) C錯。只有在兩者相比較時才使用比較級，而本句出現了狀語in the world，明顯表示不止兩者相比，故應改用最高級 (the) longest 。

22) A錯。 改為the highest。

23) D 為正確答案，“as little nourishment as possible ”意為“盡可能少的養料”。

24) A錯。改為sooner。

25) B 為正確答案，兩個短語“as a teacher of the deaf”和“ as the inventor of the telephone”相比。

26) C為正確答案。注意： 空檔后的“characteristic”是名詞而不是形容詞，所以不能填A。

27) B錯。 改為most。

28) B錯。 改為most。

29) A錯。改為rapidly。

30) A錯。改為mysteriously。

31) B為正確答案。

32) C為正確答案。

33) C為正確答案。

34) A錯。 改為such。
