今天，给大家介绍几种常用的状语从句的用法。

一、比较状语从句（Adverbial Clause of Comparison）

引导比较状语从句的从属连词有than, as；还有“the+比较级, the+比较级”句型。

【例句】

The project was completed earlier than we had expected.

You are a little heavier than when I saw you last.

He worked as fast as a skilled worker.

The further an object is the smaller it looks.

二、目的状语从句（Adverbial Clause of Purpose）

引导目的状语从句的从属连词和词组有so that, in order that, lest, for fear that, in case等。

【例句】

The teacher must speak clearly so that his students can understand well.

They climbed to the top of the building in order that they could get a bird’s-eye view of the city.

三、结果状语从句（Adverbial Clause of Result）

引导结果状语从句的从属连词和词组有so that, so…that, such…that等。

【例句】

He had overslept, so that he was late for work.

What have I done that you were so angry with me?

He was very angry, so that he left the room without saying a word.

I was in the bath, with the result that I didn’t hear the knock at the door.

四、方式状语从句（Adverbial Clause of Manner）

引导方式状语从句的从属连词和词组有as, as if, as though, the way等。

【例句】

You must do the exercises as I show you.

Mary was behaving as though she hadn’t grown up.

She’s doing her work the way I like it done.

提示：as if/ as though表示“好像，仿佛”。在其引导的状语从句中，

谓语动词常用虚拟语气，表示与事实相反。as if比as though更为常用。

【例句】

Johnson talks loudly as if he were a native French-speaker.

Tom and Marry pretended as though nothing had happened.

提示：as用于修饰动作或状态。意思相当于in the same manner that…。

as与like容易混淆，as是连词，其后接主谓结构；like是介词，其后只可接名词或与之相当的词。二者均为介词时，as意为“实质是，真像，作为”，like意为“表面像”。

【例句】

Love is to Williams as water is to fish.

He takes care of the boy as his father.（真父亲）
