                              形容词

形容词用来修饰名词或代词,表示人或事物的性质、特征或状态。

考点1、形容词的用法

1).形容词作定语,修饰名词或不定代词。

The tall man is her father.

There is something wrong with my bike.

2).形容词作表语,放在连系动词之后。

His hair gets white.

The film was wonderful.

3)大多数形容词既可作定语又可作表语,但有少数形容词只能作表语,所以又把这些形容词叫作表语形容词,其特点就是这些形容词常常是以a开头的

Afraid ,alone ,asleep ,awake ,alive, alike,ill ,well

The baby is asleep.Turn down the TV, please.

Take this medicine and you’ll get well soon .

4).形容词作宾补,放在宾语之后,与之构成复合宾语。

We must keep our classroom clean.

Don’t leave the door open.

5)某些形容词前加定冠词表示一类人或物,为复数概念,在句中起名词作用,可作主语或宾语。

The young should be polite to the old .

考点2、形容词在句中的位置

1).形容词修饰名词时,要放在名词的前面,作其定语。

The population will become a big problem.

He is a strong man.

2)形容词修饰不定代词,要放在不定代词的后面,作其后置定语

I have something important to tell you .

3)enough作形容词修饰名词时,多放在名词之前,在非正式文体中也可放在名词之后。但enough作副词用于修饰形容词、副词时,要放在被修饰词的后面。

enough time (time enough)

He ran fast enough to catch up with the others.

4)形容词短语作定语要放在被修饰词的后边,作后置定语。但复合形容词作定语时,要放在被修饰词前。

a basket full of eggs  a river fifty meters wide

a ten-year-old boy  a two-month holiday

2).形容词比较等级的用法

形容词比较等级分为原级、比较级、最高级三种形式。现将其经典用法归纳如下:

(1)、原级的用法

①句中只出现了一个人或物,没有比较对象时,要用原级。

She has a new computer.

②表示A和B两者比较,程度相同。用句型:

A+系动词+as+形容词原级+as+B

Tom is as honest as John.

③表示A和B两者比较,A在程度上不如B时,用句型:

A+系动词+not+as/so+形容词原级+as+B

The weather in Beijing is not as/so hot as that in Wuhan.

需注意的原级的用法:

①表示倍数的句型:A+系动词+数词(times)+as +形容词原级+as +B

This garden is ten times as large as that one.

② as…as possible(表示“尽可能……”)

Please hand in your homework as soon as possible.

(2)、比较级的用法

两者比较,用比较级。其句型为:

A+系动词+形容词的比较级+than+B

需注意的比较级的用法:

①在比较级前面还可用much,even,still,a little等词语来修饰,表示“…...的多”“甚至…….”“更…….. ”“  ……..一些”

②表示倍数:A+系动词+数词(times)+形容词的比较级+than+B

Our room is twice larger than theirs.

③表示“大……岁”时用“表示数量的词+比较级”来表示。

I’m two years older than you .

④“比较级+than any other+单数名词”表示“比其他的任何……都……”

⑤“比较级+and+比较级”表示“越来越……”

China is becoming more and more beautiful.

⑥“the+比较级,the+比较级 ”译为“越…….就越”

The busier he is , the happier he feels.

⑦“the+比较级+of the two” 译为“两个中比较……的”

He is the better of the two.

⑧“Which(who) is +比较级,A or B ?”译为“A和B哪一个更……?

Which one is more popular,the radio or the movie ?

(3)、最高级的用法

表示三者或三者以上(人或物)的比较,其中有一个在某一方面超过其他两个或几个时,用最高级。常用句型:A+系动词+ the+形容词最高级+ of/in

of the four     of all    of all the boys    of us

in China ,     in the world      in our school    in my family

注意:当用介词短语表示形容词最高级的比较范围时,介词后的名词或代词与句中的主语是同一类事物,并把主语包括在内时,介词用of ,当只说明是在某一空间范围内的比较时,介词用in。

需注意的比较级的用法:

① one of the+最高级+复数名词,表示“最…….之一”。

Shanghai is one of the most beautiful cities in China.

② Which(Who) is +the +最高级, A , B or C ?意指三个或三个以上的事物或人中“哪一个(谁)最…….?”

③我们可以用原级、比较级、最高级三种方式分别来表示最高级

No other student in her class is as good as she

She is better than any other student in her class.

She is the best student in her class.
