【知识点归纳】
形容词和副词是历年英语高考的重点。要复习好这一块知识点，考生
不仅要掌握其基础知识，同时要
牢记其中的重点和难点，也是高考的热点。
I.形容词、副词的作用与位置
1.形容词是用来修饰名词的，常被放在名词前作定语，或放
在系动词后面作表语。而副词则用来修饰形容
词、动词，其他副词或者句子，一般位于形容词之前，动词
之后或句子之首。以下属几种情况，须牢记：
①几个并列的形容词作定语，其语序通常为：
限定语（The、A）+ 描绘性形容词 + size（大小）+ shape（形状）+
age（年龄、时间）+
color（颜
色）+origin（国籍、来源）+material（材料）+
purpose（目的）+名词；
a heavy black Chinese steel
umbrella,
the man’s first tow interesting
little red French oil paitings
熟记口诀就可以顺利解题：限定描绘大长高，形状年龄和新老，颜色国籍跟材料，作用类别往后靠。
②形容词短语作定语，定语后置；
a language difficult to
master,
a leaning tower about 180 feet high
This is a student worth of praise.
They
will turn their motherland into a country,
beautiful and modern.
③表语形容词（afraid、alike、alon
e、asleep、awake、alive等）作定语，定语后置；
a man
alive：活着的人
有些表身体健康状况的形容词如well、faint、ill只作表语。si
ck既可作表语又可作定语，ill如作定语
意为“bad”；
④形容词作定语修饰由不定代
词one、no、any、some和every构成的复合词如anything、something等时，
通常后置；
I have something important to tell
you.
⑤enough、nearby修饰名词前置或后置，程度副词一般位于形容词、副词前面，
enough修饰形容词、
副词时，必须后置；
⑥else常用作疑问代词和不定代词的后置定语；
⑦几个副词并列作状语时，其顺序较灵活，但一般是：方式→地点→时间；
1
⑧频度副词如often、always、usually等在be动词后，行为动词前；
⑨副词作定语，定语后置；
The person there is waiting
for you.
⑩复合形容词常用作定语，个别也可以作表语。
He was a
12-year-old boy.
He is good-natured.
复合形容词的构成：
▲形容词+名词-ed：kind-
hearted好心的，white-haired白发的
▲形容词+形容词：red-
hot炽热的，dark-blue深蓝的
▲形容词+现在分词：good-
looking好看的，easy-going随和的
▲副词+现在分词：hard-
working勤劳的，fast-moving快速转动的
▲副词+过去分词：hard-
won得来不易的，newly-made新建的
▲名词+形容词：life-
long终生的，world-famous世界闻名的
▲名词+现在分词：peace-
loving爱好和平的，fun-loving爱开玩笑的
▲名词+过去分词：snow-
covered白雪覆盖的，hand-made手工的
▲数词+名词 + ed：four-
storeyed 4层楼的，three-legged 3条腿的
▲数词+名词（名词用单数）：ten-year 10年的, two-man两人的
2.形容词作伴随状语和原因状语
He spent 7days in the wind
and snow，cold and hungry.
他在风雪中度过了7天，又冷又饿。
She stared into the distance, speechless for a
long time.
她盯着远处看，好长时间不讲话。
Afraid of being
caught，the thief hid himself under a bed.
因为害怕被抓，这个小偷藏在床下面。
II.连系动词与形容词
象get,grow,become,feel,appear,prove ,look,keep,
smell,taste,sound,go,turn,remain等这些动词既可以用作
为实义动
词又可以用作连系动词，因而要根据上下文语境判断究竟是什么性质的动动词才能正确解题。
请看下面这道选择题：
▲We don't care if a hunting dog
smells_____,but we really don't want him to
smell_____.
A. well; well B. bad; badly
C. well; badly D. badly; bad
第一个“smell”是
“闻起来”的意思，是连系动词，用形容词。第二个“smell”是实义动词，用
副词来修饰；此外w
ell作形容词是表示人身体好、气色好，用在此句中不行，只能作副词用。答案
是B。句意是：“我们
不在乎猎狗闻起来难闻，但是我们确实不希望它的嗅觉力差。
III.形容词、副词比较等级的用法
注意：many,old和far比较级及最高级用法的区别
①如果后接名词时，much
more +不可数名词，many more +可数名词复数。
②old有两种比较级和最高级形式: olderoldest
和eldereldest。elder，eldest只用于兄弟姐妹的长幼
关系。
My
elder brother is an engineer.
Mary is the
eldest of the three sisters.
③far有两种比较级，farther，further..在英语中两者都可指距离。
在美语中，father表示距离，further表示进一步
I have
nothing further to say.
1.原级的用法
表示双方在程度、性质、特征等某方面相等时，用“as+原级形容词副词+
as”的结构；表示双方不相等
时，用“not so(as)+原级形容词副词+
as”的结构；表示一方是另一方的若干倍时，用“倍数+ as+原级形容
2
词副词+ as”的结构。
Xiao Wang is as
tall as Xiao Yu.
This building looks not so
(as)high as that one.
Miss Xu speaks English
as fluently as you .
This room is three times
as large as that one.
2.比较级的用法
①双方比较，表示一方超过另一方时，用“比较级+than”的结构表示；
This
picture is more beautiful than that one.
注意：
▲比较对象的一致性
请看下面这道选择题：
The weather in
China is different from__ __.
A. in
America B. one in America C.
America D. that in America
本题意为中国的天气比美
国热。比较的是天气而不是国家，C不能选。A没有名词，后句成分不
全，排除。B和D中，B中的on
e常用来代替可数名词，而that可车以代替不可数或抽象名词，所
以选D。
▲要避免将主语包含在比较对象中
（错）China is larger than
any country in Asia.
（对）China is larger than
any other countries in Asia.
▲注意比较对象的省略或隐藏：有时省略或不点明被比较的对象，而是通过语境来暗示被比较的对象。
请看下面这两道选择题：
If there were no examinations,
we should have ___ at school.
A. the happiest
time B. a more happier time C. much happiest
time D. a much happier time
本题将比较的对象隐藏在虚拟条件句中，即：与没有考试的时候相比。本题答案选D。
I
don’t think this film is by far the most boring.I
have seen____________.
A. better B.
worse C. the best D. the
worst
由前文“我认为这部电影不是最没趣的”可知，“我看过(比这部)更差的电影”，省略了than
this one。
本题答案是B。
It takes a long time to
go there by train; it's ________by road.
A.
quick B. the quickest C. much
quick D. quicker
由语境可知，句末省略了than by
train，用比较级。本题答案是D。
②表示一方不及另一方时，用“less+原级+than”的结构表示；
This
room is less beautiful than that one.
③表示一方超过另一方的程度或数量时，可在比较级前加表示程度的状语，如even、a lot、a
bit、a little、
still、much、far、yet、by fay等修饰；
He works even harder than before.
注意：by
far通常用于强调最高级。用于比较级时，一般放在比较级的后面，如在前面，应在二者中
间加“the”。
He is taller by far than his
brother.
He is by far the taller of the two
brothers.
④表示一方随另一方的程度而变化时，用“the
+比较级（主语+谓语），the +比较级（主语+谓语）”
的结构（意为“越……越……”）；
The harder he works, the happier he feels.
⑤不与其他事物相比，表示本身程度的改变时，用“比较级+ and+比较级”的结构；
The weather is getting colder and colder.
The girl becomes more and more beautiful.
⑥某些以-ior结尾的形容词进行比较时，用to代替than。这些词有inferior（劣等的
，次的）、superior（较
好的，优于……）、junior（资历较浅的）、senior（
资格较老的）、prior（在……之前）等；
He is superior to in
chemistry.
3
⑦在比较从句中为了避免重
复，我们通常用that(those)、one(ones)代替前面出现的名词。that指物,one既<
br>可指人又可指物。that可代替可数名词单数和不可数名词，而one只能代替可数名词；
The book on the table is more interesting than
that(或the one)on the desk.
A box made of steel
is stronger than one made of wood.
⑧否定词+比较级
该结构用否定形式表示肯定意义。要掌握该结构的用法，须注意以下几点：
▲该结构多为“can't ／couldn't ＋比较级”的形式
I can't
agree with you more.我再同意你的意见不过了。（或：我完全同意你的意见。）
The weather couldn't be worse.天气再糟糕不过了。
He
couldn't have done better.他做得再好不过了。
▲用于该结构中的否定词除了not之外，还有no，never，nothing等
This could give her no greater
pleasure.这使她再高兴不过了。
There's nothing
cheaper.这东西再便宜不过了。
There is no greater love
than that of a man who lays down his life for his
friends.
为朋友而放弃生命的爱是最伟大的爱。
▲当该结构中的比较级为less时，其意义为“一点也不”
试比较：He
couldn't care more.他非常介意。（或：他最关心不过了。）
He
couldn't care less.他毫不介意。（或：他最漠不关心了。）
注意：反过来用肯定形式表示否定意义。这种用法主要见于：
▲know better
than+不定式。这种结构意为“不至于”
You have a better
command of French than to make such mistakes.
你的法语较好，不至于犯这样的错误。
He is more experienced
than to do such a thing.
他比较有经验，不至于做这样的事。
▲more than…can。这种句型形式上是肯定，实际上有否定含义
The
boys in the street have become very insolent and
it is more than flesh and blood can bear.
街上的男孩变得非常无礼,到了人所不能忍受的地步。
The beauty of the
place is more than I can describe.
那地方美得无法形容。
⑨倍数表达法
▲A is three(four, etc.)times the
size(height, length etc.)of B.
The new
building is four times the size(the height)of the
old one.
这座新楼是那座旧楼的四倍大（高）这座新楼比那座旧楼大（高）三倍。
▲A is three(four, etc.)times as big(high,
long, etc.)as B.
Asia is four times as large
as Europe. 亚洲是欧洲的四倍大亚洲比欧洲大三倍。
▲A is three
(four, etc.)times bigger(higher, longer, etc.)than
B.
Your school is three times bigger than
ours.你们的学校比我们的学校大三倍。
用times表倍数通常用于三倍以上，两倍可以用twice或double.
3.最高级的用法
①三者或三者以上相比，表示最高程度时，用“the
+最高级”的结构表示。这种句式一般常有表示比
较范围的介词短语；
Zhang Hua
is the tallest of the three.
He
works(the)hardest in his class.
②最高级可被序数词以及much、by far、nearly、almost 、by no
means、not quite、not really、nothing
like
等词语所修饰；
This hat is by far much nearly
almost not nearly by no means not quite
nothing like the biggest.
4
<
br>③表示“最高程度”的形容词，如excellent、extreme、perfect等，没有最高级
，也没有比较级。
④形容词最高级修饰作表语或介词宾语的名词、代词时，被修饰的词往往省略；
He is the tallest(boy)in his class.
⑤作状语的副词最高级前可以不加定冠词。
Of all the boys he
came(the)earliest.
4.形容词和副词前面使用冠词的情况
①形容词最高级前一般要加定冠词，副词最高级前可不加冠词；
②形容词最高级前有时加不定冠词，或不加冠词，不表比较，表示“非常”；
He is a
most clever young policeman.(most=very)
The
film is most interesting.(most=very)
③as+形容词+a+单数名词；
This is as good an example
as the other is.
④表示两者间“较„„的一个”比较级前加the；
who is the older of the tow boys?
⑤在“the +
比较级…，the + 比较级…”结构中；
⑥在same前一般要加the；
⑦What
+aan+形容词+单数可数名词=How+形容词+ aan+单数可数名词
What an
interesting film it is！=How interesting a film it
is!
⑧so和such的用法
so + 形容词 副词 + that …
so + 形容词 + a（n）+ 单数可数名词 + that …
so +
many much little few + 名词 + that …
such +
a(n)+ 形容词+单数可数名词 + that „
such + 形容词 + 不可数名词
+ that …
such + 形容词 + 复数名词 + that …
下列词组中为什么只能用so不可用such？
so much progress、so
many people、so little food、so few apples等。
因为名词受many、much、little、few等表示“多或少”意义的词修饰。
下列这句中such用得对不对？（对）。为什么？
These are such
little boys that they can’t dress themselves.
因为little在这儿表示“小”，而不是表示“少”的意思。
下列so的用法是错误的：so difficult problems, so hot
weather
为什么？因为problems是复数，weather是不可数名词。
⑧有些形容词前加the 成为名词。如the poor、the rich 等。
5.由asso组成的形容词或副词短语
①as much as + 不可数名词：多达
Each stone weighs as much as fifteen tons.
②as many as + 可数名词：多达
I have as a many as
sixteen reference books.
③as early as：早在
As early as the twelfth century the English
began to invade the island.
④as far
as：远到；就……而知（论）
We might go as far as (走到)the
church and back.
As far as I know（就我所知），he has
been there before.
⑤may (might, could)as
well：不妨、不如
Then you might as well stay with us
here.
5
⑥as … as can
be：到了最……的程度，极其
They are as unreliable as they
can be.他们极其不可信。
⑦as … as one can：尽其所能
He
began to run, as fast as he could.
⑧as … as
possible：尽可能
Just get them to finish up as
quickly as possible.

IV.容易混淆的形容词、副词的辨析

deadly,friendly,lovely,likely,lonely,silly,liv
ely,brotherly,weekly等。
2.有无ly的副词意义、用法有别
②具体和抽象的关系
6
They
buried the body very deep. 他们把尸体埋得很深。（具体）

words deeply moved me. 他的话深深地打动了我。（抽象）
类似的词：highhighly,widewidely
4.搭配特别的形容词和副词 <
br>英语中有些形容词和副词与名词、动词、或另一形容词等的搭配与汉语不完全一样，在平时学习中通
过运用要把它们掌握好。

fastsound asleep睡得很香 largely due
to…主要因为
greatlyrespectedhonoured很受尊敬
badlyseriously hurtinjured伤得很严重
rainsnow
hardheavily下大雨（大雪） largesmall population人口多（少）

5.体现两句间逻辑关系的连接性副词
解决这类问题，首先要弄清形容词和副词真正含义，在解题时要弄清上下文的逻辑关系。
常用
的此类词有：besides而且、再说,instead而是，反而,though不过，可是，然而,how
ever不过，仍
然，然而,thustherefore因此，所以,furthermoremor
eover此外，而且，再者,otherwiseor否则，不
然,anyhowanyway反正，
不管怎样,even so即便如此，即使这样,or rather更确切地说等等。
请看下列选择题：
①Progress so far has been very
good. _______, we are sure that the project will
be completed on time.
A. Howeve B.
Otherwise C. Therefore D. Besides
“一直进展良好”与“按时完工”是因果关系，用therefore。本题答案是C。
②The hurricane damaged many houses and
business buildings;_____ , it caused 20
deaths.
A. or else B. therefore
C. after all D. besides
由前后语境不难确定，是要表示“此外，还有，而且”，用besides。其它选项不合语境：or
so
大约；therefore因此；after all毕竟。本题答案是D。
③Much
of the power of the trade unions has been lost. _
, their political influence should
be very
great. (2006广东)
A. As a result B. As
usual C. Even so D. So far
由前后的语意逻辑可知，所填之词应是表示“即使如此”之意，用even
so。句意：工会已经失去
很多权力了；即使这样，他们的政治影响还应当还是很大的。本题答案是C。
much和much too的区别
①too much有下列用法
too
much的含义是“太多”，充当形容词用时，too是副词，用来修饰much，后接不可数名词。
I have too much homework to do.我有太多的家庭作业要做。
too much充当副词用时，可用来修饰动词
Watching TV too
much is bad for your health.看电视看得太多对你的健康有害。
too much充当代词用时，后面不接名词，代替上下文提到的事物。
You gave
me too much.你给我的太多了。
②much
too意为“太”，much(副词)用来修饰too(副词)，以加强语气，只可起副词作用，在句中修
饰形容词或副词。
It’s much too expensive.太贵了。
You walk(much)too far yesterday.昨天你散步走得太远了。
It’s much too cold.
