在英语学习中,我们经常会遇到as引导的这样那样的状语从句。在此,我们就将as引导的以及与as相关的一些状语从句作一下小结,希望对大家学习as的用法有所帮助。
(1) 时间状语从句
① as引导时间状语从句,意为“正当……的时候”或“一边……一边……”,as所表示的动作与主句的动作同时发生。如:
He entered the room as the meeting was going on.
正当开会的时候他走了房间。
Tom sings as he works.
汤姆一边工作,一边唱歌。
② as引导时间状语从句也可以说明两种正发展或变化的情况,有“随着”之意,表示时间的推移。如:
As time goes on, the boy grows into a man.
随着时间的推移,那个男孩长成了一个男子汉。
③ as引导的时间状语从句还可以强调两个动作紧接着发生。如:
As he was going out, it began to rain.
当他出去的时候,天开始下雨了。
④ 含as的结构:as soon as... 一……就…… 如:
I’ll ring you up as soon as he comes.
他一来我就给你打电话。
As soon as she came to the classroom, she began to read English.
她一到教室,就开始读英语。
(2) 原因状语从句
as引导原因状语从句,意为“因为,由于”,与because相比,语气上较弱且较口语化,它不能回答why提出的问题,也不能放在强调句中被强调。一般地,在as引导的原因状语从句中,主句和从句并重,从句说明原因,主句说明结果。如:
As she was ill, she didn’t go to school.
(=Being ill, she didn’t go to school.)
由于病了,她没去上学。
(3) 方式状语从句
①As引导方式状语从句,意为“如同,像”。如:
Please do it as I told you.
请按照我所讲的去做。
②just as意为“正如……,犹如……”。如:
It is just as you said.
事情正如你说的那样。
注意:just as还可以表示“正当……的时候”之意,引导时间状语从句。:如:
He came just as I was leaving.
我正要走时,他来了。
③含as的结构:as if/as though 好象,仿佛。 如:
The child talks as if he were a man.
那孩子说起话来像个大人似的。
I remember it as if it were yesterday.
我记得这件事,仿佛是昨天发生似的。
The girl stood at the gate as if (she was) waiting for someone.
那个女孩站在门口好象在等人。
(4) 让步状语从句
as引导让步状语从句,意为“虽然,尽管”,从句部分用倒装语序,其结构形式为:
形容词
副词
名词(不带冠词) +as+主语+谓语
动词
如:
Child as he is, he knows a lot of things.
他虽然是个孩子,但知道许多事情。
注意:这种倒装结构中的名词前不用冠词,即不可以说A child as he is或The child as he is.
Clever as he is, he can’t do it.
尽管他很聪明,也做不了这事。
Much as she admired him, she didn’t love him.
尽管她很钦佩他,但并不爱他。
Try as I might, I couldn’t lift the stone.
尽管我试了,我还是搬不动这块石头。
Tired as they were, they walked on.
尽管很累,他们还是继续走着。
注意:在这种倒装结构中,也可以用though,但不用although,如:
Bravely though the players fought, they had no chance of winning.
尽管这些运动员们都非常地英勇,但他们依然没有赢的机会。
(5) 比较状语从句
引导比较状语从句的含as结构有as…as(和……一样),not as/so…as(和……不一样), 这类从句通常以省略形式出现; 此外还有the same as…和such…as…用于表示同等程度的比较。如:
