2015甘肃特岗教师招聘考试：英语备考之比较状语从句详解

【比较状语从句】
比较状语从句由as， than引导。

用于同等程度级的比较。否定句用not so / as...as， not the same...as。

B. than
than表示不同程度级的比较

= 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。

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)

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。
