when 与while的区别
when 与while的区别1. when指某个时间点，表示瞬间动作；while 指某个时间段，表示延续性动作。
如：用when引导的状语从句表示时间，说明一个动作发生的时候，另一个动作正在进行。
如：—What were you doing when I came into the classroom? 当我走进教室的时候你正在干什么？—I was reading. 我正在读书。
—What was he doing when I came in? 当我进来的时候他正在干什么？— He was watching TV.他正在看电视。
When I got there, she was playing the violin. 我到那里时，她正在拉小提琴。
用when引导的时间状语从句也可以表示某一个动作已发生，另一个动作已经完成，已经完成的主句的动作用过去完成时态来体现。
When they arrived at the station, the train had left.当他们到达车站的时候，火车已经离开了。
用while连接的时间状语从句一般用过去进行时，表示正在进行某一个动作时发生了另一个动作，而主句常用一般过去时。
While I was playing the violin, he came to see me.我正在拉小提琴时，他来看我了。
While he was reading, the telephone rang. 当他正在读书的时候，电话铃响了。
While we were boating on the lake, we saw a fish jump out of the water.当我们正在湖中划船时，我们看见了一条鱼跳出了水面。
注意：英语中，延续性动作是由延续性动词发出的，瞬间性动作是由非延续性动词发出的。
延续性动词和非延续性动词的区别：延续性动词是指该动作可以延续一段时间，而不是瞬间结束，如work（工作）、study（学习）、eat（吃）、watch（观看）；非延续性动词是指该动作极为短暂，瞬间便会结束，如start（开始）、begin（开始）、hit（撞）、see（看见）、knock（敲）、jump（跳）。
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。
when, while 和as 的区别及练习
when, while和as的区别及练习使用when的情况:1.两个短暂性动作同时发生或接连发生时：I took off my shoes when I got home. 我一回到家，就把鞋子给脱掉了。
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。
3.while 还可以表示然而，但是He is clever while he is very lazy. 他很聪明，但是很懒。
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。
2023暑假作业 第08练 when while as等引导的时间状语从句(解析版)
第08练when、while、as等引导的时间状语从句一、When/while/as（当…时候）1）When:when引导时间状语从句时表示“当……的时候”，when既可以指时间段也可指时间点，从句中既可用延续性动词又可用瞬间性动词，且动作既可和主句的动作同时发生又可在主句的动作之前或之后发生。
且when引导的时间状语从句中一般用一般现在时表将来（主将从现）。
e.g. When I came home my wife was cooking dinner.A）如果when引导的时间状语从句的主语与主句主语相同，而从句的谓语又是be动词时，那么从句中的主语和be可以省略;e.g. When (you are) in trouble, ask her for help.B）当when引导的时间状语从句的主语与主句主语相同时，往往还可以省略从句的主语并用“when+分词”的形式替代该状语从句。
e.g. When I came into the room (=When coming into the room), I found him lying there asleep.2）Whilewhile引导时间状语从句时表示“当……的时候”，它强调主句的动作与从句的动作同时持续地进行，用于这一用法时while引导的时间状语从句和主句中的谓语动词必须是延续性动词，或者强调主句的动作发生在从句动作的进行过程中，此时主句中的谓语动词通常是非延续性动词。
记住，从句中始终是延续性动词，且从句多用进行时态。
（while还可以表示对比，译成“然而”，放在句首可以表示“虽然”）e.g. I met her while I was at school.3）Asas引导时间状语从句时表示①“当……时”（只引导瞬间性动词，两个动作是紧密联系的，一前一后进行），②“一边……一边……”，侧重表示两个动作同时发生(包括一个主语同时进行两个动作)，③“随着”，一种动作随着另一种动作的变化而变化从句中只能接延续动词。

初中状语从句总结及练习(附答案)
状语从句练习易混引导词while, when, as的区别：1.when既可以指"时间点",与瞬间动词连用，也可以指"时间段"，与延续性动词连用（=while）。
如：When he came in, his mother was cooking.When (While) we were at school, we went to the library every day.While表示时间段,因此，while 从句的谓语动词要用延续性动词。
如：Please don't talk so loud while others are working.As与when用法相似，但着重强调主句动作与从句动作同时发生，有"随着……"或"一边……一边……"之意。
如：As you get older, you get more knowledge.随着年龄的增长，你获得的知识就越多。
2．Because,as,since 的区别：Because用于表示直接原因,回答why提出的问题，语气最强；As用于说明原因, 着重点在主句，常译成"由于"；since表示显然的或已知的理由或事实，常译成"既然"。
如：Water is very important because we can't live without it.He didn't come yesterday as his mother was ill.I'll do it for you since you are busy.3．such…that, so…that, so that 引导结果状语从句的区别：such是形容词，修饰名词; so 是副词，修饰形容词或副词。
其结构如下：1) such + a (n)+ 形容词+单数可数名词+that……2) such+形容词+复数可数名词+that ……3) such +形容词+不可数名词+that……。

第七 when while as 区别及练习
When while as区别一、根据从句动作的持续性来区分1、“主短从长”型：即主句是一个短暂性动作，而从句是一个持续性动作，此时三者都可用。
如：Jim hurt his arm while［when， as］ he was playing tennis. 吉姆打网球时把手臂扭伤了。
2、“主长从长”型：即主句和从句为两个同时进行的动作或存在的状态，且强调主句动作或状态延续到从句所指的整个时间，此时通常要用while。
I always listen to the radio while I’m driving. 我总是一边开车一边听收音机。
He didn’t ask me in; he kept me standing at the door while he read the message. 他没有让我进去，他只顾看那张条子，让我站在门口等着。
但是，若主句和从句所表示的两个同时进行的动作含有“一边……一边”之意时，则习惯上要用as。
如：He swung his arms as he walked. 他走路时摆动着手臂。
3、“主长从短”型：即主句是一个持续性动作，而从句是一个短暂性动作，此时可以用as 或when，但不能用while。
如：It was raining hard when [as] we arrived. 我们到达时正下着大雨。
二、根据主句与从句动作是否同时发生来区分1、若主句与从句表示的是两个同时发生的短暂性动作，含有类似汉语“一……就”的意思，英语一般要用as (也可用when)。
如：The ice cracked as [when] I stepped onto it. 我一踩冰就裂了。
2、若主句与从句表示的是两个几乎同时发生的短暂性动作，含有类似汉语“刚要……就”“正要……却”的意思，英语一般要用as(也可用when)，且此时通常连用副词just。
如：I caught him just when [as] he was leaving the building. 他正要离开大楼的时候，我把他截住了。
中考英语状语从句连接词用法辨析单选题30题答案解析版
中考英语状语从句连接词用法辨析单选题30题答案解析版1.I was doing my homework ______ my mother came back.A.whenB.whileC.sinceD.until答案：A。
“when”表示“当……的时候”，既可以指时间点，也可以指时间段，此句中“妈妈回来”是一个时间点，所以用“when”正确。
“while”通常表示一段时间的动作同时进行，句中“做家庭作业”和“妈妈回来”不是同时进行的一段时间，所以“while”错误。
“since”表示“自从”，引导时间状语从句时，主句通常用现在完成时，此句时态不符，所以“since”错误。
“until”表示“直到……才”，不符合此句语境，所以“until”错误。
2.She was listening to music ______ she was cooking.A.whenB.whileC.sinceD.as soon as答案：B。
“while”表示一段时间内两个动作同时进行，此句中“听音乐”和“做饭”是同时进行的动作，所以用“while”正确。
“when”虽然也可以表示“当……的时候”，但一般指一个动作发生时，另一个动作突然发生，不太符合此句语境，所以“when”错误。
“since”和“as soonas”分别表示“自从”和“一……就……”，不符合此句语境，所以“since”和“as soon as”错误。
3.______ he was reading, the phone rang.A.WhenB.WhileC.SinceD.As soon as答案：A。
“when”表示“当……的时候”，此句中“他正在读书的时候，电话响了”，符合语境，所以“when”正确。
“while”一般指一段时间的动作同时进行，句中“读书”和“电话响”不是同时进行的一段时间，所以“while”错误。
“since”表示“自从”，不符合此句语境，所以“since”错误。
when,while,as练习题及答案
when,while,as练习题及答案when, while 和 as 引导时间状语从句的用法这三个词的意思很简单，都有“当??时候”的意思, 但又有区别。
一、when 的用法观察下面的句子:1. When he was a child he was always trying out new ideas. 他小时候就常常试验一些新的设想。
2. When she came into my room, I was just readinga book. 她走进我房间时，我正在看书。
3. Were you writing when the teacher came in? 老师进来的时候，你在写信吗？4. Sorry, I was out when you called me. 对不起，你打电话来的时候我出去了。
5. He was leaving when someone knocked at the door. 他正要走，这时有人敲门。
6. I thought of it just when you opened your mouth. 就在你要说话的时候，我也想到了。
根据以上的例句，我们可以总结出一点：when 从句中的A事件，相当于主句中B事件发生的时间点。
也就是说，when 从句的重点不在动作本身发生的状态，而只是把它作为一个时间点，所以when从句多数情况下用的是一般过去时，而不用进行时, 而且, when 从句的动词大多是短暂性动词。
这种说法也可以参照。
实际上，when 从句也可以有其它的时态，但几乎也不用进行时，因为它也只是作为一个时间参照点。
例如：When the manager comes here for a visit next week, I’ll talk with him about this.下周，经理来这参观时，我会和他谈谈此事。
When的特殊用法：主句when 从句I was walking along the street when a ball hit me on the head.我正沿着路边着，就在这时一个球打在了头上。
第七whenwhileas区别及练习精编版
⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯最新料介绍⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯When while as 差别一、依据从句动作的连续性来划分1、“主短从长”型：即主句是一个短暂性动作，而从句是一个连续性动作，此时三者都可用。
如：Jim hurt his arm while ［ when， as］ he was playing tennis. 吉姆打网球时把手臂扭伤了。
2、“主长从长” 型：即主句和从句为两个同时进行的动作或存在的状态，且重申主句动作或状态连续到从句所指的整个时间，此时往常要用while 。
I always listen to the radio while I ’ m driving. 我老是一边开车一边听收音机。
He didn ’ t ask me in; he kept me standing at the door while he read the message. 他没有让我进去，他只顾看那张便条，让我站在门口等着。
可是，若主句和从句所表示的两个同时进行的动作含有“一边一边”之意时，则习惯上要用 as。
如：He swung his arms as he walked. 他走路时摇动着手臂。
3、“主长从短”型：即主句是一个连续性动作，而从句是一个短暂性动作，此时能够用as 或 when，但不可以用 while 。
如：It was raining hard when [as] we arrived.我们抵达时正下着大雨。
二、依据主句与从句动作能否同时发生来划分1、若主句与从句表示的是两个同时发生的短暂性动作，含有近似汉语“一就” 的意思，英语一般要用 as (也可用 when)。
如：The ice cracked as [when] I stepped onto it. 我一踩冰就裂了。
2、若主句与从句表示的是两个几乎同时发生的短暂性动作，含有近似汉语“刚要就”“正要却”的意思，英语一般要用as(也可用 when)，且此时往常连用副词just。
