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。
When,While,As引导时间状语从句的区别
When，While，As引导时间状语从句的区别when，while，as显然都可以引导时间状语从句，但用法区别非常大。
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和as 只能和延续性动词连用。
① Why do you want a new job when you’ve 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。
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 The students took notes as they listened．（listen为延续性动词）学生们边听课边做笔记。
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 和as从句的谓语动作必须是和主句谓语动作同时发生。
1．从句动作在主句动作前发生，只用 when。
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。
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。

②When ／While ／As she was making a phone call，I was writing a letter．（make为延续性动词）当她在打电话时，我正在写信。
when、as、while引导的时间状语从句用法区别
(1) when引导时间状语从句，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，也可用非延续性动词，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。
例如：When the decision was read out Mrs Gardner thanked the judges. 判决书宣读完，加德纳夫人向法官们表示感谢。
When the wind blows, all the doors rattle. 只要风一吹，这门就吱嘎作响。
He stopped trying, when he might have succeeded next time. 他不再试了，其实他可能下一次就成功。
When you are sitting, keep your elbow on the arm rest. 坐立时，把胳膊肘靠在扶手上。
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; 当when引导的时间状语从句的主语与主句主语相同时，往往还可以用“when+分词”的形式替代该状语从句。
例如：When (you are) in trouble, ask her for help. 当你遭遇麻烦的时候去向她求助。
When I came into the room (=When coming into the room), I found him lying there dead. 当我进入房间的时候，我发现他躺在那儿死了。
(2) while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，或者主句的动作发生在从句动作的进行过程中，主句中的谓语动词通常是非延续性动词例如：Study while you study; play while you play. 该学习的时候就学习，该玩的时候就玩。
when.whileas的区别用法
when， while和as的用法一．when，while，as在时间状语从句中的区别：①三者均可表示“当……的时候”，如果主句表示的是短暂的动作，而从句表示的是一段时间,三者可通用.如：I met Kang Li as／when／while I was walking along the street．当我沿街散步时碰见了康丽。
②when可以和延续性动词连用，也可以和短暂性动词连用;而while和as只能和延续性动词连用。
如：It was snowing when we got to the airport．当我们到达机场时，天正下着雪。
（不能用while）③as强调主句与从句表示的动作同时发生，as常表示“随着……”；“一边……,一边……；while强调主句表示的动作持续于while所指的整个时间内；when可指主、从句所述动作同时或先后发生.如:As the time went on,the weather got worse．（as表示“随着……”之意）He sang as he went along．他边走边唱。
Please write while I read．我读的时候，请写下来。
When he reached home，he had a little rest．回到家后,他休息了一会儿。
④when用于表示“一……就……"的句型中（指过去的事情）。
somebody had hardly（＝scarcely）done …when．．．＝Hardly ／Scarcely had somebody done …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.二。
as while when引导时间状语从句的区别
AS,WHILE,WHEN引导时间状语从句的区别噫，说起AS、WHILE、WHEN这三个词儿，它们在句子里头引导时间状语从句的时候，差别还是挺大的哟。
AS嘛，就好比说“跟到……一样”，它强调的是两个动作或者事情同时发生，不分先后，就像你吃饭跟到看电视一样，同时进行。
比如说，“As I was walking down the street,I saw a cat.”就是说“我走在街上的时候，看到了一只猫。
”，这里走路跟到看到猫是同时发生的。
WHILE呢，它有点“在……期间”的意思，也是说两个动作同时进行，但是它更侧重于强调一个动作在另一个动作持续进行的期间内发生。
比如说，“While I was studying,my roommate was sleeping.”就是说“我在学习的时候，我室友在睡觉。
”，这里强调的是学习这个动作的持续期间内，室友在睡觉。
WHEN呢，它就比较灵活了，可以表示“当……的时候”，既可以指两个动作同时发生，也可以指一个动作在另一个动作之前或者之后发生。
比如说，“When I got home,I found my keys were missing.”就是说“我回到家的时候，发现我的钥匙不见了。
”，这里回家跟到发现钥匙不见了，就有先后顺序了。
所以说，AS、WHILE、WHEN虽然都是引导时间状语从句的词儿，但是它们的意思和用法还是有区别的，咱们得根据句子的意思来选择合适的词儿哈。
while,as,when用来引导时间状语从句的 区别
while，as，when 都可解释为“当…时候”，用来引导时间状语从句，但有区别：
1、while 意为during the time that“在……期间”，表达一个“时间段”，不能表达“时间点”，从句的动词只限于持续性动词。
例如：
One day while he was shopping in the supermarket, he saw his ex-wife with a man.
一天，他在超市购物时，他看到了他的前妻和一个男子在一起。
Strike while the iron is hot.
趁热打铁。
2、when 意为at the time that“在…时”，多指“时间点”，例如：
When he returned from work, his wife was cooking.
他下班回家时，他的妻子正在做饭。
3、as 意为at the same time that“正当……”或“与……同时”，它兼指“时间点”和“时间段”，从句的动词既可是短暂性动词，也可是持续性动词。
例如：
The door bell rang as we were having breakfast.
正当我们吃饭的时候，门铃响了。
As the time went on，the weather got worse and worse.
随着时间的推移，天气越来越糟。
归纳：
总的说来，3者的功能区别大体可作如下描述：
while 为主句动作的发生划定一个时间的范围；
as 为主句动作的发生提供一个伴随的动作；
when 为主句动作的发生规定一个特定的时间。
while、when和as的用法区别
while、when和as的用法区别第一篇：while、when和as的用法区别as when while 的区别和用法as when while的用法一、as的意思是“正当……时候”,它既可表示一个具体的时间点，也可以表示一段时间。
as可表示主句和从句的动作同时发生或同时持续，即“点点重合”“线线重合”；又可表示一个动作发生在另一个动作的持续过程中，即“点线重合”，但不能表示两个动作一前一后发生。
如果主句和从句的谓语动词都表示持续性的动作，二者均可用进行时，也可以一个用进行时，一个用一般时或者都用一般时。
1、As I got on the bus，he got off.我上车，他下车。
（点点重合）两个动作都是非延续性的2、He was writing as I was reading.我看书时，他在写字。
（线线重合）两个动作都是延续性的3、The students were talking as the teacher came in.老师进来时，学生们正在讲话。
（点线重合）前一个动作是延续性的，而后一个动作时非延续性的二、while的意思是“在……同时（at the same time that)”“在……期间(for as long as, during the time that）”。
从while的本身词义来看，它只能表示一段时间，不能表示具体的时间点。
在时间上可以是“线线重合”或“点线重合”，但不能表示“点点重合”。
例如：1、He was watching TV while she was cooking.她做饭时，他在看电视。
（线线重合）2、He was waiting for me while I was working.我工作的时候，他正等着我。
（线线重合）3、He asked me a question while I was speaking.我在讲话时，他问了我一个问题。
（点线重合）三、when的意思是“当……时候（at the time that）”“无论什么时候（whenever）” “一……就……（as soon as）” “在……以后（after）”。

②As I was walking to work, I listened to music.（as表示“一边……，一边……”之意）当我步行去上班时，我一边听音乐
一边走路。
三、when引导的时间状语从句常用于表示“突然”、“意外”等含义；while和as引导的时间状语从句常用于表示“同时发生”、“伴随着”等含义。
①When I was cooking dinner, the smoke alarm suddenly
went off.（表示突然发生）当我在做晚饭时，烟雾警报突然响了。
②While I was studying for the exam, my roommate was watching TV.（表示同时发生）当我在为考试研究时，我的室
友在看电视。
③As she was walking along the beach, she picked up seashells.（表示伴随着）当她沿着海滩散步时，她捡起了贝壳。
2. 随着时间的推移，中国变得越来越强大和富裕。
3. 小姑娘们一边走一边唱歌。
5. 伤心的母亲坐在路边，一边哭一边喊叫。
1. 当我读完这本书后，你可以借阅。
2. 下周经理来参观时，我会和他谈论这个问题。
when--while--as-的区别
when, while, as 的区别[说明]作连词时，when,while和as都有“当……时候”的意义，引导时间状语从句，但应注意它们的区别。
1) 如主句谓语动词表示的是短暂动作，从句时间状语指一段时间，三者可通用。
例如：Peter came in while /as I was watching TV.当Peter进来的时候我正在看电视。
I was watching TV when Peter came in.当Peter进来时我正在看电视。
2) as 和when 可与非延续性动词连用，而while 只能与延续性动词连用。
例如：He came in when/ as I was going to bed.我正要上床睡觉，他进来了。
3) as 和while可用来指一段时间，但as 强调主句与从句表示的动作同时发生，while强调主句表示的动作是在while 从句的动作延续中发生。
例如：As my mother sang those old songs, tears ran down her cheeks.当我妈妈唱起那些老歌时，眼泪顺着她的脸颊流了下来。
I came in while he was reading an interesting book in his room.我进来的时候他正在房间里看一本有趣的书。
三者都有“当……时候”的意思，注意以下用法与区别：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，三者都可用。
如：He fell asleep when [while, as] he was reading. 他看书时睡着了。
I met him when [as, while] I was taking a walk in the park. 我在公园散步时遇到了他。
注：as 用于引出一个持续性动词表示“在……期间”时，其谓语通常只能是那些含有动作(action)和发展(development) 意味的动词，一般不能是那些不用于进行时态的动词(如be, seem, love, want, agree, see, know, have 等)，所以下面一句中的while 不能换为as：A：I’m going to the post office. 我要去邮局。
when和while as的用法区别口诀
when和while as的用法区别口诀when，while，as引导时间状语从句的区别when，while，as显然都可以引导时间状语从句，但用法区别非常大。
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和as只能和延续性动词连用。
① Why do you want a new job when you’ve 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。
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和as从句的谓语动作必须是和主句谓语动作同时发生。
1.从句动作在主句动作前发生，只用 when。
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，as都可使用。
3.当主句、从句动作同时进行，从句动作的.时间概念淡化，而主要表示主句动作发生的背景或条件时，只能用 as。
这时，as常表示“随着……”;“一边……，一边……”之意。
① As the time went on，the weather got worse.(as表示“随着……”之意)② The atmosphere gets thinner and thinner as the height increases.随着高度的增加，大气越来越稀薄。
4.在将来时从句中，常用when，且从句须用一般时代替将来时。
三、when用于表示“一……就……”的句型中(指过去的事情)。
sb.had hardly(=scarcely) done sth.when...=Hardly / Scarcely had sb.done sth.when...。
Whenwhileas的区别和用法综合整理
Whenwhileas的区别和用法综合整理When、while和as是三个常用的英语连词，它们都有表示时间、原因或条件等关系的功能，但在具体用法上有一些区别和细微差异。
本文将对这三个连词的用法进行综合整理和分析。
一、When的用法1. 表示“当...的时候”When引导时间状语从句，表示两个事件同时发生或一个事件发生在另一个事件之后。
例如：- When I woke up, the sun was already shining.（当我醒来时，太阳已经照耀着。
）2. 表示“每当”、“无论何时”When可以引导名词性从句，用来表示经常发生的动作或状态。
例如：- I always go for a walk when I feel stressed.（我每当感到压力时都会出去散步。
）3. 表示“如果”、“假如”当when引导条件状语从句时，表示某个条件成立时发生的情况。
例如：- When it rains, I like to stay indoors.（如果下雨，我喜欢呆在室内。
）二、While的用法1. 表示“当...的时候”While引导时间状语从句，表示两个事件在同时发生。
例如：- She was watching TV while I was cooking.（她在看电视，我在做饭。
）2. 表示“与此同时”While还可以用作副词，表示在某个时间段或情况下同时进行的动作。
例如：- She likes to listen to music while working.（她喜欢一边工作一边听音乐。
）3. 表示对比While用作连词时，可以引出对比的两个事物或情况。
例如：- While I enjoy summer, my friend prefers winter.（虽然我喜欢夏天，但是我的朋友更喜欢冬天。
）三、As的用法1. 表示“由于”、“因为”As引导原因状语从句，表示一个事件的原因。
例如：- As it was getting late, we decided to leave.（因为时间已晚，我们决定离开。
时间状语从句中when,while,as的区别
时间状语从句中when,while,as的区别时间状语从句中when, while, as的区别1)when引导从句时，主从句的动作有先有后，也可以同时进行,从句的动作可以是持续性的，也可以是短暂的。
如：When I got to the airport, the plane had already taken off. （主先从后）（短暂性）When I lived there, I used to go to the seaside on Sundays. (同时) （持续性）When the movie ended, the people went back. （从先主后）2)while侧重主从句动作的对比，且从句的动词必须是持续性的。
如：While we were chatting she was looking at the time table on the wall．3)as引导从句时侧重主从句动作同时或几乎同时进行，从句的动作可以是持续性的，也可以是短暂的。
如：Sometimes I watch TV as I am having breakfast．4）when和while还可以是并列连词，意思分别是“就在这时”，“然而”。
如：I was having a rest on the sofa when the telephone rang．They were surprised that a child should work out the problem while they couldn’t .注：并列连词when常用与以下句型中：①…was/were doing…when…（正在做…突然）②…was/were about to do…when…（刚要做…突然）③…was/were on the point of doing…when…(刚要做…突然)④…had just done…when….(刚一…就)⑤Hardly/Scarcely had…done…when…(刚一…就)好了，以上就是关于时间状语中when, while, as区别的介绍，还请大家在平时勤加练习。
when，while，as引导时间状语从句的区别是什么？
when，while，as引导时间状语从句的区别是什么？状语从句在整个句子中充当的就是“状语”的语法成分，而“时间状语从句”，自然就是这个从句在整个句子中充当了时间状语的语法功能，这就是我们判断的原则。
可以充当时间状语从句的连词有很多，如when(当...时)，while(当...时)，as(随着…)等等，我们下面就来仔细辨认一下这些引导词。
1when/while/as 当……时，随着（一）when：表示“时间点”1. When my mother came into the house(=When coming into the house), she found me lying there awake .当我妈妈走进屋子时，发现我醒着躺在那。
这个句子主句是一般过去时，从句是一般过去时。
同时要注意，当从句主语和主句主语一致时，往往可以省略从句的主语，将从句谓语转化为现在分词形式即“when Ving”这种短语形式代替状语从句；（二） while：表示“时间段”1、while they are arranging everything for their children, they are also interfering their growth.当他们在为子女安排一切的同时, 也在干涉他们的成长。
请大家注意以下几点：A. While译为“当...时”或“在…期间”，while引导的从句通常为进行时，即指一段时间，表示从句动作在进行时，主句动作也在进行中，所以此时主句一般也是进行时；B. While还能译为“趁”和“虽然/然而”，while译为“虽然/然而”时是让步状语从句。
如果发现while引导的状语从句与主句方向相反时，肯定是让步状语从句，表示“虽然/然而”，这一点要区分清楚。
（三）as：表示“随着”1、As T ony listened to those words, smile appeared on his face.随着托尼听到这些话, 微笑出现在了他的脸上。
When,While,As引导时间状语从句的区别之欧阳语创编
When，While，As引导时间状语从句的区别when，while，as显然都可以引导时间状语从句，但用法区别非常大。
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和as只能和延续性动词连用。
① Why do you want a new job when you’ve 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。
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 The students took notes as they listened．（listen为延续性动词）学生们边听课边做笔记。
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和as从句的谓语动作必须是和主句谓语动作同时发生。
1．从句动作在主句动作前发生，只用 when。
①When he had finished his homework，he tooka short rest．（finished先发生）当他完成作业后，他休息了一会儿。
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。
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，as都可使用。
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。
②When ／While ／As she was making a phone call，I was writing a letter．（make为延续性动词）当她在打电话时，我正在写信。
when,while和as引导时间状语从句的用法之欧阳术创编
when, while 和 as 引导时间状语从句的用法一、when 的用法如果只从现象来看，when 从句用的最多的是一般过去时，而主句的时态没有限制,根据具体情况而定。
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 reading a 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 on the point of 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。
7. I had hardly[scarcely] closed my eyes when someone knocked at the door.我刚一闭上眼，就有人在敲门了。
根据以上的例句，我们可以总结出一点：when 从句的A事件，相当于另一个事件B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 多数情况下用的是一般过去时，则不用正在进行时。
因为如果用正在进行时，它表示的就是一段时间而不是一个时间点了。
根据这一点，有的文章补充说：when 从句的动词大多是瞬时动词。
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。
as, while,when 与让步状语从句之欧阳道创编
as, while,when 与让步状语从句1．as引导的让步状语从句，句子要求用倒装结构，此时的as相当于though，但比though引导的让步状语从句语意更强烈，表现力更强。

Young as he is，he knows many things．他年纪虽小，知道的事可不少。
2）副词或动词原形＋as＋主语……，＋主句Much as I like it，I will not buy it．虽然我很喜欢这东西，但不想买它。
Try as I would，I couldn't lift the stone．不管我使多大劲也搬不起这块石头。
Do as I might，I could not finish the duty．虽然我努力做了，但仍未完成这项任务。
2．while引导的让步状语从句，while相当于though ／although。
如：While Smith loves his daughter，he is strict with her．虽然史密斯爱他的女儿，但仍严格要求她。
While I admit his good points，I can see his shortcoming．虽然我承认他的优点，但我还是看到了他的缺点。
While I believe it，I must consider．我虽信，但还要考虑一下。
3．when引导的让步状语从句，when相当于though ／although。
如：We'll try to finish the work in time when we are short of manpower．虽然我们缺乏人力，但我们还是要按时完成这项工作。

When，While，As引导时间状语从句的区别
欧阳家百（2021.03.07）
when，while，as显然都可以引导时间状语从句，但用法区别非常大。
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和as只能和延续性动词连用。
① Why do you want a new job when you’ve 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。
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 The students took notes as they listened．（listen为延续性动词）学生们边听课边做笔记。
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和as从句的谓语动作必须是和主句谓语动作同时发生。
1．从句动作在主句动作前发生，只用 when。
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。
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。
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，as都可使用。
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。
②When ／While ／As she was making a phone call，I was writing a letter．（make为延续性动词）当她在打电话时，我正在写信。
3．当主句、从句动作同时进行，从句动作的时间概念淡化，而主要表示主句动作发生的背景或条件时，只能用 as。
这时，as常表示“随着……”；“一边……，一边……”之意。
① As the time went on，the weather got worse．（as表示“随着……”之意）
② The atmosphere gets thinner and thinner as the height increases．随着高度的增加，大气越来越稀薄。
③As years go by，China is getting stronger and richer．随着时间一年一年过去，中国变得越来越富强了。
④The little girls sang as they went．小姑娘们一边走，一边唱。
⑤The sad mother sat on the roadside，shouting as she was crying．伤心的妈妈坐在路边，边哭边叫。
4．在将来时从句中，常用when，且从句须用一般时代替将来时。
①You shall borrow the book when I have finished reading it．在我读完这本书后，你可以借阅。
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。
三、when用于表示“一……就……”的句型中（指过去的事情）。
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。
②I had hardly ／scarcely entered my room when the telephone rang．＝Hardly ／Scarcely had I entered my room when the telephone rang．我刚一走进房门，电话就响了。
When\while\as的区别
①when是at or during the time that, 既指时间点，也可指一段时间；
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。
②when说明从句的动作和主句的动作可以是同时，也可以是先后发生；while则强调主句的动作在从句动作的发生的过程中或主从句两个动作同时发生。
③由when引导的时间状语从句，主句用过去进行时，从句应用一般过去时；如果从句和主句的动作同时发生，两句都用过去进行时的时候，多用while引导，如：
a. When the teacher came in, we were talking.
当此句改变主从句的位置时，则为：
While we were talking, the teacher came in.
b. They were singing while we were dancing.
④when和while 还可作并列连词。
when表示“在那时”；while表示“而，却”，表对照关系。
如：
a. The children were running to move the bag of rice when they heard the sound of a motor bike.
孩子们正要跑过去搬开那袋米，这时他们听到了摩托车的声音。
b. He is strong while his brother is weak.
他长得很结实，而他弟弟却很瘦弱。
具体你可以参考这一段。
