第九讲 形容词副词
一.形容词的作用
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。
1. 作定语:特别注意多个形容词作定语时的排列顺序。形容词短语作定语,定语后置。
a language difficult to master, a leaning tower about 180 feet high
2. 作表语:通常与系动词be , ge ( http: / / www.21cnjy.com )t , grow , become , feel , appear, prove , seem, look, keep, smell, taste, sound , turn, remain 等连用。
如: Our classroom is c ( http: / / www.21cnjy.com )lean. The weather is getting cooler and cooler.
3. 作宾补:如:The news made every one happy.
4. 与定冠词一起表示某一类人或物,在句中可作主语、宾语。
如:The rich and the poor live very different lives.
5. 作状语,表示伴随状况、原因、结果等。 ( http: / / www.21cnjy.com )如:
He went to bed, cold and hungry.
She stared into the distance, speechless for a moment.
二.副词的作用
副词的定义:副词是一种用来 ( http: / / www.21cnjy.com )修饰动词,形容词,副词或全句的词,说明时间,地点,程度,方式等概念。一般位于形容词之前,动词之后或句子之首。
1. 作状语:通常修饰动词、形容词、副词或整个句子。
如:We should constantly review our lessons.
2. 作表语:Now summer is in.
3. 作定语:如:
The popul ( http: / / www.21cnjy.com )ation here is getting smaller and smaller.
One my way home, I saw an old lady sitting under a tree alone.
4. 作宾补(副词构成复合宾语的情况较少)
如:I saw Mrs Green ( http: / / www.21cnjy.com ) out with her husband.
5. 构成短语:表示位置的副词可与动词构成短语,表示特定的意思。
如:pick out (挑选),turn up (露面)
副词的分类:
1. 时间和频度副词: now,t ( http: / / www.21cnjy.com )hen,often,always,usually,early,today, lately, next,last,already,generally,frequently, seldom,ever,never,yet,soon,too, immediately, hardly,finally,shortly, before, ago,sometimes, yesterday
2. 地点副词: here, there, ( http: / / www.21cnjy.com )everywhere, anywhere, in, out, inside, outside, above, below, down, back, forward, home, upstairs, downstairs, across, along, round , around, near, off, past, up, away, on.
3. 方式副词: care ( http: / / www.21cnjy.com )fully, properly, anxiously, suddenly, normally, fast, well, calmly, politely, proudly, softly, warmly
4. 程度副词: muc ( http: / / www.21cnjy.com )h,little, very,rather,so,too,still, quite, perfectly, enough, extremely, entirely,almost, slightly.
5. 疑问副词: how, when, where, why.
6. 关系副词: when, where, why.
7. 连接副词: how, when, where, why, whether.
三.容易出错的几个注意点
1. 下列以a-开头的形容词通常只用作表语:
表语形容词(afraid、alike、 ( http: / / www.21cnjy.com )alone、asleep、awake、alive ashamed , afloat (飘浮的), aware (知道的)等。)作定语,定语后置。如a man alive。 a man afraid (害怕的人),the greatest man alive (健在的最伟大的人) the only child awake (唯一醒着的孩子)有些表身体健康状况的形容词如well、faint、ill只作表语。sick既可作表语又可作定语。
另外,unable, content ( http: / / www.21cnjy.com )(满足的), ill(生病的),通常不可用作定语;ill 作定语时,通常是"坏的,邪恶的"意思。尽管现在已有人用ill作前置定语表示生病的,well表示健康的,习惯上还是用sick, healthy等作前置定语为好。
注意:
(1)多数以a-开头的形容词不直接 ( http: / / www.21cnjy.com )用very修饰,通常习惯说法如:
very much alone 非常孤单的/wide awake 十分清醒的/sound / fast asleep 熟睡的
(2)以a-开头的形容词本身带有副词来修饰时,可以用作前置定语,如:
a fast asleep boy 熟睡的男孩;the wide awake soldiers 十分清醒的士兵
(3)用作定语,修饰由不定代词one、n ( http: / / www.21cnjy.com )o、any、some和every构成的复合词如anything、something等时,通常后置。如:
I have something important to tell you.
(4)else常用作疑问代词和不定代词的后置定语。
(5)几个并列的形容词作定语,其语序 ( http: / / www.21cnjy.com )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。如:
a heavy black Chinese steel umbrella,
the man’s first tow interesting little red French oil paitings
2. 有些形容词(如wooden)通常不能用作表语。
我们不说The table is wo ( http: / / www.21cnjy.com )oden 而应改为:The table is of wood. 或The table is made of wood.
不能用作表语,只能作定语的常用形容词还有:inner 内部的,outer 外部的, former 较前的, latter 较后的,utter完全的,upper上面的,real真正的,mere仅仅的,live[laiv]活的, only唯一的,aged年老的
3. 有些形容词(如possible)作表语时,通常不用"人"作主语。
我们不说He is possi ( http: / / www.21cnjy.com )ble to attend the meeting. 而应该说It is possible for him to attend the meeting.
这类形容词常见的有: possible ( http: / / www.21cnjy.com ), improbable, convenient, inconvenient等
注意:这类句型中当动词不定式与句子主语存在着逻辑动宾关系时,主语用"人"是可以的,如:
He is impossible to teach. = It is impossible to teach him.
这句也是正确的:She is necessary to get along well with.
4. worth, worthwhile 和worthy
1) be worth 表示"价值"时,后面可以直接接名词或-ing形式;
2) 在It is worth while 结构中,it 为形式主语,后面可接-ing形式,也可接动词不定式
3) worthy 可修饰名词作定语,如a ( http: / / www.21cnjy.com ) worthy man 可尊敬的人, a worthy life 有价值的 / 有意义的生活,与 of 连用时可作后置定语,如:
a cause worthy ( http: / / www.21cnjy.com ) of support 值得支持的事业。
worthy of 作表语时,后面可接名词或-ing形式(常用其被动式)
4) worthy后面也可接动词不定式,被动含义时也须用不定式的被动式。
5. 有些副词与形容词形式相同,表示同一含义,常见的有:early , late , fast , high , straight
6. 副词的位置
1) 修饰形容词和其它副词时,通常放在 ( http: / / www.21cnjy.com )被修饰词之前,但enough、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。
如: This is a very useful tool
He doesn't work hard enough.
2) 频度副词 (often , us ( http: / / www.21cnjy.com )ually , seldom , hardly , never, sometimes, always等)要放在实义动词的前面, be 动词、助动词、情态动词的后面。如:
We often go to the park.
He is always ready to help others.
3) 地点副词、时间副词、方式副词常位于 ( http: / / www.21cnjy.com )句末。如:
I remember that I met him somewhere.
Everything went smoothly.
4) 同时出现几种副词时的排列顺序:方式副词→地点副词→时间副词。如:
He made his model plane perfectly there yesterday.
5) 作定语的副词放在被修饰词之后。
People here are very friendly to me.
7. 某些以-ly结尾的词是形容词而不是副词。
如friendly , lively , ( http: / / www.21cnjy.com )lovely, lonely, likely, deadly , silly , orderly、ugly、brotherly、timely等。
8. 表愿意(无-ly)和引申意(有-ly)的副词:
deep深, wide宽广, hig ( http: / / www.21cnjy.com )h高, low位置低; deeply深入地, widely广泛地, highly高度地, lowly地位卑微。
有些副词有两种形式(加-ly后变为另一副词),但意义不同。
如: late 迟,晚;lately 近来;high 高;highly 高度地
有无-ly意义大不相同的副词:
dead 完全,绝对:be dead asleep
deadly非常:be deadly tired
pretty相当:be pretty certain that
prettily漂亮地:be prettily dressed
close近:Don’t sit close.
closely密切地:Watch closely!
late晚、迟:arrive late, come late
lately最近:I haven’t seen him lately(recently).
9. 复合形容词的构成

四.形容词和副词的比较级用法
1. 两者相比(A=B),用"as + 原级 + as"表示。
原级的构成和用法:
构成:形容词、副词的原级即本身。
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。
Xiao Wang is as tall as Xiao Yu.
Miss Xu speaks English as fluently as you .
2. 两者相比(A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 + 原级形容词/副词 + as”的结构。如:
This building looks not so (as)high as that one.
This room is three times as large as that one.
3. 两者相比(A>B),用"比较级+than"表示。
比较级的用法:
①对方比较,表示一方超过另一方时,用“比较级 + than”的结构表示。如:
This picture is more beautiful than that one.
②表示一方不及另一方时,用“less + 原级 + than”的结构表示。如:
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 ( http: / / www.21cnjy.com )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 far等修饰。如:

注意:英语的比较级前如无even、still或yet等时,译成汉语时可用“较”或“一些”或不译出,一般不可有“更”。如:

另注意: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”。如:
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, ( http: / / www.21cnjy.com )用“the + 比较级(主语 + 谓语),the + 比较级(主语 + 谓语)”的结构(意为“越厖越厖”)。如:
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。如:
The weather is getting colder and colder.
The girl becomes more and more beautiful.
⑥在比较从句中为了避免重复,我们通常 ( http: / / www.21cnjy.com )用that(those)、one(ones)代替前面出现的名词。that指物,one既可指人又可指物。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 tab ( http: / / www.21cnjy.com )le is more interesting than that(或the one)on the desk.
A box made of steel is stronger than one made of wood.
⑦倍数表达法。
A. A is three(four, etc.)times the size(height, length etc.)of B.

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。如:
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muc ( http: / / www.21cnjy.com )h、by far、nearly、almost 、by no means、not quite、not really、nothing like等词语所修饰。如:

③表示“最高程度”的形容词,如excellent、extreme、perfect等,没有最高级,也不能用比较级。
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。如:
He is the tallest(boy)in his class.
⑤形容词和副词前面使用冠词的情况。
·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。

·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”。如:

·在“the + 比较级,the + 比较级”结构中。

五、几组重要的词语辨析
1. very 和much的区别。
(1)可分等级的形容词和副词前使用very不用much。
(2)表示状态的过去分词前用ver ( http: / / www.21cnjy.com )y。a very frightened boy, a very tired child, a very complicated problem, 一般的情况下,以-ing、-ed结尾的分词多用much、very much / greatly等修饰。如:We were greatly shocked by the news about Tom. I was much amused by Jack’s attitude。
(3)已转化为形容词的现在分词前用very。如:very interesting / worrying / exicting。

There’s far too little opportunity for adventure these days.
We’ve got far too many eggs and far too few egg cups.
(5)关于原级形容词要记住下列固定的修饰结构:

b. 修饰以a-开头的形容词,多有 ( http: / / www.21cnjy.com )特殊的修饰词:quite alone, very much alone, wide awake, fast asleep, very much afraid。
c. 修饰一些特殊形容词的修饰语有: ( http: / / www.21cnjy.com )be well worth, much the same, freezing cold, quite different, terribly cold / frightening。

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
注意:下列结构中只能用so不可用suc ( http: / / www.21cnjy.com )h,当名词前有many、much、little、few等表示“多、少”的词修饰时,如 so much progress、so many people、so little food、so few apples等。但当little表示“小”时用such。如:These are such little boys that they can’t dress themselves.
3. 其他几组词的辨析。
(1)ago、before:
