您好,现在瑶瑶来为大家解答以上的问题。when和while引导的时间状语,when和while引导的时间状语从句相信很多小伙伴还不知道,现在让我们一起来看看吧!

1、when,while引导时间状语从句的区别如下:一、when可以和延续性动词连用,也可以和短暂性动词连用;而while只能和延续性动词连用。

2、 ① Why do you want a new job when youve got such a good one already?(get为短暂性动词)你已经找到如此好的工作,为何还想再找新的? ②Sorry,I was out when you called me.(call为短暂性动词)对不起,你打电话时我刚好外出了。

3、 ③Strike while the iron is hot.(is为延续性动词,表示一种持续的状态)趁热打铁。

4、 ④ The students took notes as they listened.(listen为延续性动词)学生们边听课边做笔记。

5、 二、when从句的谓语动词可以在主句谓语动作之前、之后或同时发生;while从句的谓语动作必须是和主句谓语动作同时发生。

6、 1.从句动作在主句动作前发生,只用 when。

7、 ①When he had finished his homework,he took a short rest.(finished先发生)当他完成作业后,他休息了一会儿。

8、 ②When I got to the airport,the guests had left.(got to后发生)当我赶到飞机场时,客人们已经离开了。

9、 2.从句动作和主句动作同时发生,且从句动作为延续性动词时,when,while都可使用。

10、 ①When /While /As we were dancing,a stranger came in.(dance为延续性动词)当我们跳舞时,一位陌生人走了进来。

11、 ②When /While /As she was making a phonecall,I was writing a letter.(make为延续性动词)当她在打电话时,我正在写信。

12、 3.在将来时从句中,常用when,且从句须用一般时代替将来时。

13、 ①You shall borrow the book when I have finished reading it.在我读完这本书后,你可以借阅。

14、 ②When the manager comes here for a visit next week,Ill talk with him about this.下周,经理来这参观时,我会和他谈谈此事。

15、 三、when用于表示“一……就……”的句型中(指过去的事情)。

16、 sb.had hardly(=scarcely) done sth.when...=Hardly / Scarcely had sb.done sth.when... ①I had hardly /scarcely closed my eyes when someone knocked at the door.=Hardly / Scarcely had I closed my eyes when someone knocked at the door.我刚一闭上眼,就有人在敲门了。
