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。
