as 用作连词有哪些用法

 

as 用作连词用法如下:

一、表示伴随

意为“随着”。如:

As time passed, things seemed to get worse. 随着时间的推移,情况似乎变得更糟了。

若其后不接从句,而接名词,则用介词 with 表示“随着”。如:

With the development of modern agriculture and industry, more and more waste is produced. 随着现代工农业的发展,污染越来越严重了。

二、表示让步

意为“虽然”“尽管”,要用于倒装句(相当于 though,但语气稍弱)。如:

Boy as he was, he behaved like a girl. 他虽然是个男孩,但举止却像个女孩。

Much as I like you, I couldn’t live with you. 我尽管很喜欢你,却不能和你一起生活。

Try as he would [might]he couldn’t open the door. 他试过多次了,却仍打不开门。

三、表示时间

意为“当……时候”。如:

He dropped the glass as he stood up. 他站起来时,把杯子摔了。

As I was coming here, I met your brother. 我来这里时碰到了你的弟弟。

注意,as 引导时态状语从句时,其谓语动词通常只能是动作动词,而不能是静态或状态动词。如:

她出生后不久父母双亡,是由姑母抚养大的。

误:Her parents died as she was a baby and she was brought up by her aunt.

正:Her parents died when she was a baby and she was brought up by her aunt.

四、表示原因

引导原因状语从句时,其谓语动词可以是动作动词,也可以是状态动词。如:

As you weren’t there I left a message. 因为你不在那里,我留了个信儿。

另外,引导原因状语从句,可用以下这样的倒装语序。如:

Tired as she was, I decided not to disturb her. 因为她累了,我就决定不打扰她了。

Writing hurriedly as she was, she didnt notice the spelling errors. 因为写得仓促,她没有注意其中的拼写错误。
