    when,while都有“当……时候”的意思.

      when既可表示某一点时间,也可以表示某一段时间 .

      在when引导的时间状语从句中,其谓语动词可以是延续性的,也可以是非延续性的,可与主句中的谓语动词同时发生,也可在其后发生.

      例如:

      1、I was just reading a book when she came into my room.

      她走进我房间时,我正在看书.

      (二)、while只能表示某一段时间,不能表示某一点时间.在while引导的时间状语从句中,其谓语动词只能是延续性的,而且也只能与主句中的谓语动词同时发生或存在.

      例如:

      1、While Jim was mending his bike,Lin Tao came to see him.

      正当吉姆修自行车时,林涛来看他.

    while是during the time that,只指一段时间,因此when引导的时间状语从句中的动词可以是终止性动词,也可以是延续性动词,而while从句中的动词必须是延续性动词。

    题1: 英语中的when和while在(句子)用法上有什么区别?[语文科目]

    朋友,

    据相关资料和本人的理解,when和while最大的区别就是:when一般是接一个平常的事件或者是延续性词组,而while主要接正在发生的动作或者说是非延续性的事件.

    题2: 【While的用法及while与when的区别.】[英语科目]

    when,while这三个词都有"当……时候"之意,但用法有所不同,使用时要特别注意.

    ①when意为"在……时刻或时期",它可兼指"时间点"与"时间段",所引导的从句的动词既可以是终止性动词,也可是持续性动词.如:

    When I got home,he was having supper.我到家时,他正在吃饭.

    When I was young,I liked dancing.我年轻时喜欢跳舞.

    ②while只指"时间段",不指"时间点",从句的动词只限于持续性动词.如:

    While I slept,a thief broke in.在我睡觉时,盗贼闯了进来.

    辨析

    ①when从句与主句动作先后发生时,不能与while互换.如:

    When he has finished his work,he takes a short rest.每当他做完工作后,总要稍稍休息一下.(when = after)

    When I got to the cinema,the film had already begun.当我到电影院时,电影已经开始了.(when=before)

    ②when从句动词为终止性动词时,不能由while替换.如:

    When he came yesterday,we were playing basketball.昨天他来时,我们正在打篮球.

    ③当从句的谓语是表动作的延续性动词时,when,while才有可能互相替代.如:

    While / When we were still laughing,the teacher came in.正当我们仍在大声嬉笑时,老师进来了.

    ④当从句的谓语动词是终止性动词,而且主句的谓语动词也是终止性动词时,when可和as通用,而且用as比用when在时间上更为紧凑,有"正当这时"的含义.如:

    He came just as (or when) I reached the door.我刚到门那儿,他就来了.

    ⑤从句的谓语动词如表示状态时,通常用while.如:

    We must strike while the iron is hot.我们应该趁热打铁.

    ⑥while和when都可以用作并列连词.

    Mike is tall while his brother is short.迈克的个子很高,然而他弟弟很矮.

    Mary was on her way home when two big boys stopped her.玛丽正走在回家的路上,这时两个大个子男孩拦住她.
