as的用法总结及典型句子
as作为介词时,用法和语义较单一,其含义为“作为”。

但是as作为连词词性时,
其用法和功能较多,可以引导各类从句。

你的钢笔书写起来和我的一样流畅。

as引导原因状语从句、时间状语从句、方式状语从句、让步状语从句和定语从句。

例如:He smiled as he said goodbye to me。

一、as作连词的用法
1.as...as的用法
as...as意为"和……一样",表示同级的比较。

使用时要注意第一个as为副词,第二个as为连词。

其基本结构为:as+adj./adv.+as。

例如:
(1)Your pen writes as smoothly as mine.你的钢笔书写起来和我的一样流畅。

(2)This film is as interesting as that one.这部电影和那部电影一样有趣。

其否定式为not as/so+adj./adv.+as。

例如:
This dictionary is not as/so useful as you think.这本字典不如你想象的那样
有用。

若有修饰成分,如twice,three times,half,a quarter等,则须置于第一个as之前。

例如:
Your bag is twice as expensive as mine.你的袋子比我的贵一倍。

2、as引导时间状语从句
此时,as译作“当……时候”,可以放在主句之前,也可以放在主句之后。

例如:
He smiled as he said goodbye to me.
他向我道别时微笑了一下。

As she was walking in the park,she heard a girl singing.
她在公园里散步时,听到一位女孩在唱歌。

I sang an English song as I went along the river.
我边沿河边走边唱英文歌。

3.as用作连词引导原因状语从句
as,because,since都可以表示因果关系,连接原因状语从句,含义是"因为,由于",但它们有区别:because表示的语气最强;as一般放在句首,语气较弱,较口语化;since
常常用在书面语中,表示多为对方已知的、或稍加分析便可得知的原因,有时可译作"既然"。

例如:
(1)He will succeed because he is in earnest.他一定会成功,因为他很认真。

(2)Since you are so sure of it he”ll believe you.既然你对此如此有把握,他
会相信你的。

(3)As rain has fallen,the air is cooler.因为下过雨,空气比较清爽。

4、as引导让步状语从句
此时,as译作“尽管”。

当as引导让步状语从句时,不把as放在从句的开头,而是将充当从句主要成分的形容词、副词、分词、动词原形或不加冠词的单数可数名词置于前面。

(1)将表语放在句首,再将as放在表语和主语之间。

例如:
Child as he is,he knows quite a lot of things.
虽然他还是个孩子,但他懂得很多事情。
