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 是两个常见的连接词，用于引导时间状语从句。

它们在用法和含义上有一些相似之处，但也存在明显的区别。

理解并正确使用 when 和 while，对于准确表达时间和动作的关系非常重要。

首先，我们来看 when 的用法。

When 可以表示“当的时候”，它既可以指一个时间点，也可以指一段时间。

当when 表示一个时间点时，从句中的动作通常是短暂性的。

例如：“When I arrived home, my mother was cooking dinner”（当我到家时，我妈妈正在做晚饭。

）在这个句子中，“arrived”是一个短暂性动作，表示到达的瞬间。

When 也可以表示一段时间，此时从句中的动作通常是持续性的。

比如：“When I was a child, I often played in the park”（当我还是个孩子的时候，我经常在公园里玩。

）这里“was a child”是一个持续的状态。

接下来，我们探讨 while 的用法。

While 通常表示“在期间”，强调主句和从句的动作同时发生，并且两个动作都是持续性的。

例如：“While I was doing my homework, mysister was watching TV”（当我在做作业的时候，我妹妹在看电视。

）在这个句子中，“was doing”和“was watching”都是持续性的动作。

比较 when 和 while，我们可以发现以下几个主要区别。

一是动作的性质。

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。

二是主从句动作的关系。

When 引导的从句动作可以发生在主句动作之前、之后或同时；而 while 从句中的动作通常与主句动作同时进行。

三是侧重点不同。

When 更侧重于动作的突然发生或某个具体的时间点；while 则更强调动作的同时进行和持续。

The main school holidays are from mid-December till early February，when the days are long and warm. 学校的主要假期是从12 月中旬到2 月初，这段时间里白天长而且很温暖。

Do you remember the time when the three of us went on a holiday in Guilin？你还记得我们三个人在桂林度假的那段时光吗？二、作从属连词，引导状语从句。

2. 表示条件，相当于if。

when做并列连词的用法

w h e n做并列连词的用法 TTA standardization office【TTA 5AB- TTAK 08- TTA 2C】when 和引导时间状语从句的从属连词when 是不同的。

这主要表现在以下几个方面： 1. 位置：when 引导时间状语从句时，该从句可放在主句之前也可放在主句之后；而并列连词 when 只能位于两个分句之间，而且前面常常有逗号。

例如： Come when you please. 你高兴来就来吧。

（ when 为从属连词） When I saw him， he was writing to a friend of his. 我看见他时，他在给一个朋友写信。

（ when 为从属连词） I was taking a walk， when I came across him. 我正在散步，突然碰见了他。

2. 意义：when 作从属连词用时，它所引导的从句表示主句中谓语动词动作发生的时间，即作“当……时”解；而并列连词when 连接的两个分句中，第一个分句表示的是背景，第二个分句表示的是一种突然的、意想不到的情况或过早发生的事情。

when 通常含“这时突然”之义。

例如：I was thinking of this，when I heard my name called. 我正想着这件事，突然听到有人叫我的名字。

I had just fallen asleep，when the boor-bell rang. 我刚入睡，门铃突然响了起来。

这种意义在孤立的句子中可以理解到，在文章中更能体会得到。

如在“ I was wandering thro ugh the street when I caught sight of a tailor's shop ”一句中，“在街头漫步”只是“看见有家缝纫店”的时间，其后作者怎样走进缝纫店，想要什么样的衣服，怎样受到伙计的奚落，又怎样受到老板的奉承等情景均与“漫步街头”没有直接的因果关系。

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 这两个词都是用来引导时间状语从句的，但它们在用法和意义上存在着一些明显的区别。

掌握这些区别对于我们正确理解和运用英语句子至关重要。

首先，让我们来看看 when 的用法。

When 既可以表示“当……时候”，也可以表示“就在这时”。

当 when 表示“当……时候”时，从句的动作和主句的动作可以是同时发生，也可以是先后发生。

例如：“When I was a child, I often playedin the park”（当我还是个孩子的时候，我经常在公园里玩。

）在这个句子中，“我是个孩子”和“在公园里玩”这两个动作是先后发生的，先成为孩子，然后才有在公园玩的经历。

再比如：“I was doing my homework when my mother came back”（当我妈妈回来的时候，我正在做作业。

）这里，“妈妈回来”和“我正在做作业”这两个动作是同时发生的。

而 when 表示“就在这时”时，常用于 be doing sth when 这个结构，意思是“正在做某事，就在这时……”。

例如：“I was walking along the street when suddenly someone called me”（我正在街上走，就在这时突然有人叫我。

）接下来，我们看看 while 的用法。

While 通常表示“在……期间；当……的时候”，强调主句的动作和从句的动作在同一时间段内同时发生，并且从句的动作通常是延续性的。

例如：“While I was reading, my sister was watching TV”（在我读书的时候，我妹妹在看电视。

）在这个句子中，“读书”和“看电视”这两个动作是同时进行的。

需要注意的是，while 引导的从句中常用进行时态，而 when 引导的从句中可以用一般时态，也可以用进行时态。

“When”作连词时的用法及译法总结

“When”作连词时的用法及译法总结对英语学习者来说，when是一个常见的单词，所以一看到when就会脱口而出“当……时候”.这种翻译有时会闹出笑话甚至与其本意“南辕北辙”.因此，熟练掌握when作连词时的几种用法尤为重要。

小编结合自己的教学经历对when的用法及译法做如下总结：一、When作从属连词，引导状语从句1. when 译为“当……时候”这是when 最基本的用法，引导时间状语从句。

1）从句可放句首或句末。

放句首时，从句后面用逗号；放句末时，不用逗号。

【典例】The whole world were very anxious when themissing Malaysia Airlines Flight MH370 was reported.当马航失联客机MH370被报道时，世人都很着急。

When he was yet a child, he was fond of swimming.当他还是个孩子的时候，就喜欢游泳。

It was March 22,2014 Michelle Obama delivered aspeech at Peking University.A.thatB.whenC.sinceD.before解析此题考查when 的用法“当……时候”.句意为：“米歇尔·奥巴马于2014年3月22日在北京大学演讲。

”【高考链接】（2013年安徽卷）It's mucheasier to make friends you have similar interests.A. unlessB. whenC. even thoughD. so that解析此题考查状语从句的连接词。

when 表时间。

句意为：“当你们有相似的兴趣时，你们会更容易成为朋友。

”所以答案是B.2）when既可引导持续性动作，又可引导短暂性动作。

它可以表示主句的动作和从句的动作同时发生，或从句的动作发生在主句动作之前。

过去进行时when和while

过去进行时的讲与练一、含义：(1)过去进行时表示过去某一时刻或者某段时间正在进行或发生的动作，常和表过去的时间状语连用。

(2) 过去进行时表示感情色彩与现在进行时相似，过去进行时也可表示满意、称赞、惊讶、厌恶等感情色彩，也通常与always，forever等副词连用。

e.g：They were always quarrelling. 他们老是吵架。

二、过去进行时的构成和用法：肯定形式：主语+was/were+doing否定形式：主语+was not (wasn't)/were not (weren't)+doing疑问形式：Was/Were+主语+doing。

常与之连用的时间状语有，at that time/moment, (at) this time yesterday (last night/Sunday/week…), at+点钟+yesterday (last night / Sunday…)，when 和while 引导的时间状语从句。

三、when/while引导的时间状语从句①由when/while 引导的时间状语从句。

常用句型：a. 主句（主语 + was/were + doing … when + 一般过去时的句子）；表示主句动作发生的过程中，另一个意想不到的动作发生了。

We were talking when the teacher came in.=While we were talking, the teacher came in.b. 主句（主语 + was/were + doing … while +主语 + was/were + doing …）；主句与从句的动作都是延续性动词或同时发生的，两句都用过去进行时的时候，多用while引导★★★注意：when和while的区别：都意为“当……时候”，when引导的句子谓语动词用短暂性动词或延续性动词都行；但while引导的句子谓语动词只能用延续性动词，不能用短暂性动词。
