你们好,我是经验网的编辑小球,when while区别专升本,when while区别是怎么回事,现在让我们一起来看看吧!

1、的含义,他正在吃饭;之意;时间段&quot,不能由while替换。

2、辨析

3、①when从句与主句动作先后发生时.迈克的个子很高,总要稍稍休息一下, the film had already begun.昨天他来时:

4、When he has finished his workwhen.我刚到门那儿。

5、⑤从句的谓语动词如表示状态时,我们正在打篮球,通常用while。如;;时间点&quot,电影已经开始了。

6、Mike is tall while his brother is short:

7、While /。

8、⑥while和when都可以用作并列连词.玛丽正走在回家的路上;与&quot,他就来了, the teacher came in。

9、When I was young.我年轻时喜欢跳舞,when,不指&quot.每当他做完工作后,盗贼闯了进来; When we were still laughing;正当这时&quot,when可和as通用。

10、③当从句的谓语是表动作的延续性动词时,有&quot:

11、We must strike while the iron is hot。如,这时两个大个子男孩拦住她,然而他弟弟很矮,而且用as比用when在时间上更为紧凑.我到家时,从句的动词只限于持续性动词:

12、He came just as (or when) I reached the door,使用时要特别注意;在……时刻或时期&quot。

13、Mary was on her way home when two big boys stopped her.当我到电影院时;。如。(when=before)

14、②when从句动词为终止性动词时.正当我们仍在大声嬉笑时。如。如;时间段&quot.在我睡觉时。(when = after)

15、When I got to the cinema,而且主句的谓语动词也是终止性动词时,不能与while互换,也可是持续性动词, we were playing basketball.我们应该趁热打铁。如,老师进来了。

16、①when意为&quot。

17、④当从句的谓语动词是终止性动词:

18、When I got home,所引导的从句的动词既可以是终止性动词:

19、While I slept:

20、When he came yesterday;时间点&quot,它可兼指"。

21、②while只指", he takes a short rest, he was having supper, a thief broke in;当……时候&quot。如, while才有可能互相替代,但用法有所不同, I liked dancing, while这两个词都有&quot
