as的用法总结as是英语考试中用得比较多的一个词,也是很多学生反映较难掌握的一个词。
as的词性较多,用法也较复杂,因此掌握该词会对英语学习很有帮助。
下面笔者就对as的用法作一个简单的归纳。
一、as作为从属连词,可以引导下列从句:1、as引导时间状语从句,意为“正当……的时候”、“一面……一面……”、“随着……”,从句可放主句之前或主句之后。
As I was coming here, I met your brother.As he walked on, he felt himself getting more and more tired.【知识拓展】:as与when, while都是引导时间状语从句的从属连词,含义都是"当……的时候"。
但它们有区别:用when时,从句的动作可以与主句的动作同时发生,也可以先于主句的动作发生;用while时,从句的动作为一过程,主句动作与从句动作同时进行或在从句动作过程中发生;用as时,主句和从句的动作同时发生,具有延续的含义。
例如:It was snowing when he arrived at the construction site.他到达工地时,天正在下雪。
He was watching TV while his mother was cooking.他母亲做饭时他在看电视。
You will grow wiser as you grow older.你会随着年龄的增长而越来越聪明。
2、as引导原因状语从句,意为“由于”大多位于主句之前,偶尔在前或后。
As this question is of great importance, we will discuss it once again.Water, as it occurs in nature, is never very pure.We couldn…t send the children to school as life was very hard in those days.【知识拓展】: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”。

![as用法总结](https://img.taocdn.com/s3/m/3cc065fb32d4b14e852458fb770bf78a65293a23.png)
as用法总结一、用作连词的as1.引导时间状语从句,表示“当……的时候”,其用法与when和while类似。
例如:As a child (When he was a child), she was sent to six different schools.此用法中XXX表示从句与主句动作同时进行,意为“一边……一边……”,一般不与状态动词连用。
例如:XXX.as还可以表示一动作紧接着另一动作发生,说明另一动作的结果,有“随着……”的含义。
例如:As time went by, we found he was an honest man./As he grew older, XXX.例1 It wasn’t until nearly a month later________ I received the manager’s reply.A. XXX解析:本题的as中与when一起作为干扰项,容易使考生往时间状语从句上思考,事实上本题是强调句,正确选项是D。
2.引导原因状语从句,表示“由于,因为”,相当于because,但通常置于句首。
比方:As XXX, I trust his XXX.3.引导妥协状语从句,平日可与although或though通用,但语序分歧,although或though用于句首,as用于倒装布局。
例如:Young as I am, I already know what career I want to follow. /Although(或Though)I am young,I already know what career I want to follow.as透露施展阐发妥协用于倒装布局,平日将从句的表语、状语或动词前置。
假如表语有冠词a/an,需去掉。
1比方:Great scholar as he is, he is lacking in common sense./Much as I like you, I couldn’t live withyou./Try as he would, he couldn’t open the door.例 2 _____ he has limited technical knowledge, the older worker has a lot of experience.A. XXX解析:as虽然有引导让步状语从句用法,但本题不是倒装结构,故正确答案应是D。
