二、as的用法

① when作"当……的时候"解,可以指较短的(一点)时间,也可指一段时间。如:

When the clock struck twelve, all the lights in the street went out.
② while常表示一段较长的时间或一个过程,强调主句谓语动词与从句谓语动词同时发生。如:
Work while you work. Play while you play.
③ 但属下列情形时,只用as, 而不用when或while。
A) 用于表示同一个人的两种动作交替进行,指"一边……,一边……"。如:
The girl dances as she sings on the stage.
He looked behind from time to time as he went forward.
B)表示两个同步发展的动作或行为,译为"随着……"。如:

D) 后接名词表示某一年龄段时,用as。如:

（2）as=since, 作"既然"、"由于"解,引导原因状语从句,常用来表示已为人们所知或显而易见的原因或理由。如:
As / Since you're not feeling well, you may stay at home.
As he wasn't ready in time, we went without him.
（3）as=in the way that, 作"像"、"按照……的方式"解,引导方式状语从句。如:
He speaks English as Americans do.
Remember, you must do everything as I do.
（4）用于as...as...或not so/ as...as...中,前一个as是副词,后一个as是连词,引导比较状语从句。如:
They helped the old man as often as possible.
I don't speak English so/ as well as he does.
（5）作"虽然"、"尽管"解,引导让步状语从句。常用倒装语序,即adj. /adv. / n.+ as +主语+谓语+主句。如:
Tired as they were, they walked on.
Child as he is, he knows a lot. (child前不用冠词)
2、 as作关系代词,引导定语从句,作"正如"、"这一点"解。如:
He is very careful, as his work shows.
As is well-known, Taiwan belongs to China.
另外,当先行词被the same, such等词修饰时,常用as来引导定语从句。如:
Such a clever boy as he can learn anything quickly.
I was reading the same book as he bought yesterday.
3、 as作介词的用法:
as引导的介词短语大多用作状语,as译为"作为";少数情况可引起宾语补足语。如:
As a League member, I'll take the lead in everything. (状语)
She works as a doctor. (状语)
