[初二] 形容词和副词的比较等级

[日期:2007-04-29]   [字体: ]

(1)形容词和副词有原级、比较级和最高级。原来的形式称为原级,表示“比较……”的称为比较级,表示“最……”的称为最高级。形容词和副词的比较级和最高级的变化方法如下:

①符合规则的:

情  况
加  法
例  词
一般情况
直接加-er;-est
tall-taller-tallest
fast-faster-fastest
以e结尾的词
直接加-r;-st
nice-nicer-nicest
large-larger-largest
以“辅音字母+y”结尾的词
变y为i再加-er;-est
dry-drier-driest
lazy-lazier-laziest
easy-easier-easiest;
heavy-heavier-heaviest
以一个辅音字母结尾的词
辅音字母双写再加-er;-est
thin-thinner-thinnest
big-bigger-biggest
hot-hotter-hottest

②不规则的形容词和副词的比较级和最高级如下表:

原级

比较级

最高级

good/well

better

best

bad/ill

worse

worst

many/much

more

most

little

less

least

far

farther/further

farthest/furthest

例如:

a.—How are you today?

—I'm feeling worse than yesterday.

b.Germany has more people than France.

c.I think“My Heart Will Go On”is one of the best songs in 1998.

d.Which would you like best,tea,orange juice or water?

③双音节(以“辅音字母+y”的除外)及多音节的形容词和副词比较级和最高级变化方法是:在形容词或副词前面加more,most构成。例如:

a.Which is more interesting,Lesson Five or Lesson Six?第五课与第六课哪一个比较有趣?

b.I think that's the most popular piece of music at the moment.我想那是现在最流行的音乐。

(2)形容词和副词的比较级的用法如下:

①在表示程度相同时,用“as+形容词或副词的原级+as+比较状语从句”句型。例如:

Jim is as tall as his brother.

Bruce didn't come to the classroom as early as Dick yesterday.

②在表示一方不如另一方时,“not as /so+形容词或副词的原级+as+比较状语从句”句型。例如:

Lesson Three is not so easy as Lesson Two.It's much more difficult.第三课不如第二课简单,它难一些。

③在表示一方超过另一方时,要用“形容词或副词比较级+ than +比较状语从句”句型。例如:

Peter is fatter than his brother.

④在表示三个或三个以上的人或事物中程度最高时,用句型“the +形容词或副词的最高级(+名词)+in /of /among(名词的复数形式或代词的宾格)”,副词的最高级前面的the可以省略。例如:

Which do you like best,tea,orange juice or water?

Of all stars,the sun is the nearest to the earth.所有星体中,太阳离地球是最近的。

—Which is the hottest season of the year?

—Summer.

—一年中哪一个季节最热?

—夏季。

⑤有些形容词由于受本身涵义的限制,没有比较级和最高级。如:dead,empty,round(圆的),sure,woolen等。例如:

This bottle is empty.There's no water in it.

⑥形容词比较级前面常用much,far,even,a lot,a little等词修饰。例如:

I am a little stronger than you.我比你强壮一点儿。

This street is much straighter than that one.这条路比那条直的多。

In this country,it's very cold in November,but it's even colder in December.

(3)级别之间的转换

①原级与比较级之间的转换

A.倍数+as...as→倍数+比较级+than。例如:

This book is twice as thick as that one.→

This book is once thicker than that one.

B.not so...as与比较级之间的转换。例如:

Tom knows much more about computers than any other student in his class.→No one in his class knows so much about computers as Tom.

Miss Zhang isn't so old as Miss Wang.→Miss Wang is older than Miss Zhang./Miss Zhang is younger than Miss Wang.

②比较级与最高级之间的转换:

A.比较级+than any other +名词单数。例如:

Wei Hua is the tallest boy in his class.→Wei Hua is taller than any other boy in his class.

B.比较级+than +any of the other +名词复数。例如:

Robert is better than any of the other students in the school.→ Robert is the best student in the school.

C.比较级+than +anyone else。例如:

He spoke English more quickly than anyone else.→He spoke English most quickly.

D.No one +谓语+比较级+sb.例如:

No one does the work better than Sam in his office.→Sam can do the work best in his office.

(4)级别的惯用法

①“比较级+and+比较级”,表示“越来……越……”,其形式为 -er and -er或more and more +部分双音节词和多音节词。例如:

The car is running faster and faster.It seems to be flying.

Our school is becoming more and more beautiful.

②“the +比较级,the+比较级”,表示“越……越……”。例如:

—How many books do you need?—The more,the better.

—Actually,the busier he is,the happier he feels.
