when和while的用法和区别
when和while的用法和区别When 和 While 的用法和区别在英语学习中，when 和 while 这两个词常常让学习者感到困惑。
它们都可以用来引导时间状语从句，但在具体的用法和所表达的含义上却存在着一些差异。
下面我们就来详细探讨一下 when 和 while 的用法和区别。
一、When 的用法1、表示“当时候”，引导的动作可以是短暂性的，也可以是持续性的。
例如：When I got home, my mother was cooking （我到家时，妈妈正在做饭。
）在这个句子中，“got home”是短暂性动作。
2、还可以表示“就在这时，突然”。
例如：I was walking along the street when suddenly someone called me （我正在街上走着，突然有人叫我。
）3、 When 可以用来询问具体的时间。
例如：When did you come back? （你什么时候回来的？）二、While 的用法1、表示“在期间，当时候”，引导的动作通常是持续性的。
比如：While I was reading, he was playing games （我在读书的时候，他在玩游戏。
）这里“was reading”和“was playing games”都是持续性动作。
2、强调主句动作和从句动作同时发生。
例如：While he was doing his homework, I was watching TV （他在做作业的时候，我在看电视。
）三、When 和 While 的区别1、动作的性质When 引导的从句动作既可以是短暂性的，也可以是持续性的；而while 引导的从句动作通常是持续性的。
例如：When the doorbell rang, I was having a bath （门铃响时，我正在洗澡。
）（“rang”是短暂性动作）While I was sleeping, the phone rang （我睡觉的时候，电话响了。

I picked up the phone when it rang. 当电话响的时候，我就接起了电话。
2.经常与年龄连用When I was 28 years old, I was working in New York.3.可以与延续性和短暂性动词连用Lily was sleeping when he called. 他电话来的时候，Lily正在睡觉。
He called when Lily was sleeping. Lily正在睡觉的时候，他打电话进来。
使用while的情况：1.当主句和从句都为进行时，指两个动作动作同时I was watching TV while my father was sleeping.我在看电视，我的爸爸在睡觉。
2.While 后面可以跟延续性动词，不能能短暂性动词。
He called while Lily was sleeping. Lily正在睡觉的时候，他打电话进来。

使用as的情况:1.As后面跟延续性动词He went back as his mother was cooking. 当他妈妈正在煮饭的时候，他回来了。
2.As 可以引导让步状语从句，但要倒装Child as he is, he is popular with a lot of people. 尽管他是小孩，但是他受很多人的欢迎与喜爱。
Try as he might, he still couldn’t make progress. 尽管他也尝试了，但是他仍然没有获得进步。

英语人教版八年级下册while 和 when 的用法区别
when和while的用法和区别while和when都是表示同时，到底句子中是用when还是while主要看从句和主句中所使用的动词是短暂性动作（瞬时动词）还是持续性动作。
1、若主句表示的是一个短暂性的动作，而从句表示的是一个持续性动作时，两者都可用。
如：He fell asleep when [while] he was reading. 他看书时睡着了。
I met him when [while] I was taking a walk in the park. 我在公园散步时遇到了他。
2、若主、从句表示两个同时进行的持续性动作，且强调主句表示的动作延续到从句所指的整个时间，通常要用while。
如：Don’t talk while you’re eating. 吃饭时不要说话。
I kept silent while he was writing. 在他写的时候，我默不作声。
3、若从句是一个短暂性动作，而主句是一个持续性动作，可以when 但不用while。
如：When he came in, I was listening to the radio. 他进来时，我在听收音机。
It was raining hard when we arrived. 我们到达时正下着大雨。
4、若主、从句表示的是两个同时(或几乎同时)发生的短暂性动作，一般要用when。
如：I thought of it just when you opened your mouth. 就在你要说的时候，我也想到了。
至于什么是短暂性动作，什么是持续性动作，其实有个很简单的规律。
就是如果是进行时态，一般是持续性的。
如果是过去式，一般是短暂性动作。
