(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.
