比較狀語從句的基礎知識

狀語從句指句子用作狀語時，起副詞作用的句子。比較狀語從句是其中的一種，主要運用于形容詞和副詞的原級、比較級及最高級的句子之中。

原級：as…as(和……一樣)，not so(as)…as …(和不一樣);

比較級：more…than(更);

最高級：The most…in/of， the + 形容詞+est…of/in。

常用引導詞：as(同級比較)，than(不同程度的比較);特殊引導詞：the more … the more … ; no … more than;not A so much as B。

比較狀語從句的用法

A.as...as, the same as

用于同等程度級的比較。否定句用not soas ?as, not the same ?s。

B.than

than表示不同程度級的比較

He is two inches taller than his father.

= He is taller than his father by two inches.

注意：

在比較從句中通常把和主句重復的部分省掉，如果把省略部分補上，而顯得累贅或不合乎習慣。

莉莉是一個不如露西那樣聰明的女孩。(如說成：Lily isn't so clever a girl as Lucy is clever 顯得累贅)

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

這是表示比例的比較，意思是越……就越……。第一個the more 也可以看成是一個條件。

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