【英语语法】that和as引导的比较状语从句

比较状语从句基本用法：

表示比较关系的状语从句通常是由than和as引导：

than引导的比较状语从句：

She made fewer mistakes than you did.

There were more casualties than was reported.

They work harder than we do.

The shirt is more expensive than they think.

as引导的比较状语从句：

He knows as much about America as we do.

I haven't done as much as I was expected.

The task is not so easy as it sounds.

He is as stubborn as a mule is.

注：由于此类从句中有些成分经常要避免和主句的表达发生重复，所以常有省略，看起来结构不太完整。

例如：

The task has been completed earlier than they eapected.

【译文】此任务完成得比他们估计得要早。

He ate a lot more than was good for him at the dinner.

【译文】他晚饭吃得太多了。

He looked forward，as did his secretary，to the completion of the building.

【译文】他和他的秘书都期盼着这座建筑的竣工。

These proposals sought to place greater restrictions on the use and copying of digital information than existed in traditional media.

【译文】和传统媒体相比，这些建议的目的是要对数字信息的使用和复制更加严格地加 以限制。

此外，as表示比较时，可采用much as和just as来加强语气。

例如：

It swims above the sea floor just as its ancestors did.

【译文】他们和自己的祖先一样，在海底游泳。

They are endeavoring to disguise this fact much as John did in the late 1950s.

【译文】他们试图掩盖事实真相，这在很大程度上类似于约翰在20世纪五十年代晚期的所 作所为。
