as作为介词的用法：【第四篇】

1、引导限制性定从句。

①用于the same...as结构中。

This is the same book as I read last week.这本书和我上周读的那本是一样的。

He isn’t the same person as he used to be.

②用于such...as结构中。

I have never heard such story as he is telling.

I don’t like such books as he recommends. 我不喜欢他推荐的那些书。

③用于"as/so +adj. + a/an + n. (单数) + as "结构中

I am not so strong a man as I was.我已经没有从前那么强壮了。

2、引导非限制性定从句，修饰整个主句或主句的一部分，可在句首、句中、句末。当 as 在从句中做主语时，从句的谓语动词常是被动语态或系表结构。在从句中做宾语时，从句的谓语动词常是情态动词 + 动词原形。

As is often the case, we have overfull filled the production plan.

This machine, as might be expected, has stopped operating.

He came very early this morning, as (was) usual.

She is late, as is often the case.她迟到了，这是经常的事。(先行词是整个主句)

To shut your eyes to facts, as many of you do, is foolish.

对事实视而不见--你们好多人都是如此的愚蠢。(先行词是不定式短语)

此外还有： as has been said before/ as may be imagined / as is well known/ as we all can see/ as often happens/ as has already been pointed out等等。
