比较状语从句的基础知识

状语从句指句子用作状语时，起副词作用的句子。比较状语从句是其中的一种，主要运用于形容词和副词的原级、比较级及最高级的句子之中。

原级：as…as(和……一样)，not so(as)…as …(和不一样);

比较级：more…than(更);

最高级：The most…in/of， the + 形容词+est…of/in。

常用引导词：as(同级比较)，than(不同程度的比较);特殊引导词：the more … the more … ; no … more than;not A so much as B。

比较状语从句的用法

用于同等程度级的比较。否定句用not soas ?as, not the same ?s。

B.than

than表示不同程度级的比较

He is two inches taller than his father.

= He is taller than his father by two inches.

注意：

在比较从句中通常把和主句重复的部分省掉，如果把省略部分补上，而显得累赘或不合乎习惯。

Lily isn't so clever a girl as Lucy is.

莉莉是一个不如露西那样聪明的女孩。(如说成：Lily isn't so clever a girl as Lucy is clever 显得累赘)

The child sang as sweetly as a nightingale.

这孩子歌唱得同夜莺般婉转。

C.the more..., the more...

这是表示比例的比较，意思是越……就越……。第一个the more 也可以看成是一个条件。

The more you read, the better you understand.

你看的书越多，你懂得就越多。(= If you read more, you will understand better.)

The busier he is, the happier he feels.
