一、时间状从中连接词when的用法小结：

1、when引导的时间状从的谓语动词可以是可延续的，也可以是表短暂性的动词，可用于主句和从句动作同时发生或从句动作先于主句动作。例：

When I lived there,I used to go to the seashore on Sundays.

2、可用作并列连词，其意义是“那时，这时”，相当于and at this\that time.常用于以下句式：

was about to do sth. … when…\

be (on the point of) doing sth. …when…(刚要…这时突然…)

e.g.I was about to stop pretending to being listening to the class to listen to what the teachers

said when Mr. Li shouted at me so loudly that the whole class can hear.

3、还可以表示原因“既然”，相当于since,considering that.如：

It was foolish of you to take a taxi when you could easily walk there in 5 minutes.

二、时间状从中连接词while 的用法小结：

1、while 引导的动作必须是持续性的，强调某一段时间，主从句动作同时发生，或主从句中的动作或事物在从句中的动作或事情的进展过程中发生。如：

Please don’t talk so loud while others are working.

2、while作为并列连词，意为“然而，却”，表示对比。

I have to give up because of you while I like it so much.

三、只用as,不用when或while的情况

1、用于表示同一个人的两种动作交替进行，指“一边…一边…”，如：

The girl sings as she goes to school.

2、表示两个同步发生的动作或行为，如：

As time went by,she became more and more beautiful.

3、表示两个动作紧跟着发生，如：

As he was going out,is began to rain,

4、接在名词后面表示某一个年龄段时。如：

四、连接词when,while,as的用法区别:

1、while引导的时间状语从句的谓语动词必须是可持续的，而when引导的时间状语从句的谓语动词既可以是可持续的，也可以是表短暂性动作的动词。

When\While he was eating his breakfast,he heard the door bell rang.

When I stopped my car,a man came up to me.(while不可用)

2、从句动作发生在主句动作之前时，只能用when 引导，不可用while\as,如：

3、表示“随着……”,连词用as,不用when\while,如：
