时间状语从句
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
一、when 的用法

when 从句的动词大多是瞬时动词， 多数情况下用的是一般过去时，不用正在进行时，而
主句的时态没有限制,根据具体情况而定。

When she came into my room, I was just reading a book.
Were you writing when the teacher came in? 老师进来的时候，你在写信吗？ Sorry,
I was out when you called me. 对不起，你打电话来的时候我出去了。

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
二、while 的用法

while 从句的侧重点在于描述动作正在发生的状态，它的意思是：当while 事件正在发生的
时候，另一件事如何如何。所以，while 从句一般用正在进行时。而另一件事的状态没有硬性
的要求，根据具体情况而定。例如：

1. While my wife was reading the newspaper, I was watching TV.

当妻子正在看报纸的时候，我正在看电视。

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

3. While they were talking, the bell rang. 正在他们谈话的时候，上课铃响了。

4. You can’t do your homework while you’re watching TV.

你不能一边看电视一边做家庭作业。

5. While John was sitting biting his nails, I was working out a plan to get us
home. 约翰坐在那里咬指甲时，我正在制定一个回家的计划。

while 表示的是一段时间，是一个过程。因此，如果含有“一段时间”的含义的时候，就可以用while。

6. Strike while the iron is hot. 趁热打铁。

这句话中，是说趁着铁是热的这段时间，赶紧打铁。如果换成 when 意思就变了，相当于
说铁只热了一下，打一下，然后铁就冷了。这显然不符合文意。

三、as 的用法

as 从句表示的也是一件事情正在发生，另一件事也正在进行当中。但与 while 从句不同
的是，as 从句一般不用正在进行时，而是一般过去时。as 从句一般可以翻译成“边……
边……”。例如：

1. 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。

2. The students took notes as they listened. 学生们边听课边做笔记。

3. As we talked on, he got more and more excited. 我们继续往下谈的时候，他越来
越兴奋。

4. The little girls sang as they went. 小姑娘们一边走，一边唱。

5. Just as he caught the ball, there was a tearing sound.

当他抓住球的时候，有一种撕裂的声音。

as 表达的事件，往往只是主句动作发生的背景或条件时，as 只是一个次要的时间说明，
不像while 从句，有强调 while 动作本身的意思。因此，as 常常翻译成“随着……”之意。

1. As the time went on，the weather got worse. 随着时间的推移，气候更加糟糕。

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。

3. As 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。

少数情况下，如果强调动作正在发生，as 从句也可以用正在进行时。这只能算是特例了。

1. The sad mother sat on the roadside, shouting as she was crying.

伤心的妈妈坐在路边，边哭边叫喊。

2. As we were going out, it began to snow. 正当我们出门时，雪开始下起来。

3. He came in as I was going to bed. 我正要上床睡觉，他进来了。

四、when, while, as 的互换

如果从句动作和主句动作同时发生，并且从句动作为延续性动词时，when，while，as 可
以互换使用。
1. When While As we were dancing, a stranger came in.

当我们跳舞时，一位陌生人走了进来。 [dance 为延续性动词]

2. When While As she was making a phone call, I was writing a letter.

当她在打电话时，我正在写信。 [make为延续性动词]

3. WhileWhen As I was walking down the street, I noticed a police car in front
of the

bank.

我顺着马路往前走时，发现银行门前停着一辆警车。

五、比较while, when, as

1）as, when 引导短暂性动作的动词。

Just as Just when When I stopped my car, a man came up to me.

我刹车后，有一个人向我走来。

2）当从句的动作发生于主句动作之前，只能用when 引导这个从句，不可用as 或 while。

When you have finished your work, you may have a rest.

干完活后，你可以休息一下。

3）从句表示“随时间推移”连词能用as，不用when 或while。

As the day went on, the weather got worse. 日子一天天过去，天气越变越坏。

2）比较until和till

此两个连词意义相同。肯定形式表示的意思是“做某事直至某时”，动词必须是延续性的。
否定形式表达的意思是“直至某时才做某事”。动词为延续性或非延续性都可以。正确使用这
两个连词的 关键之一就在于判断句中的动词该用肯定式还是否定式。

肯定句：I slept until midnight. 我一直睡到半夜时醒了。

Wait till I call you. 等着我叫你。

（在肯定句中可用before代替。例如：Let's get in the wheat before the sun sets.）

否定句：She didn't arrive until 6 o'clock. 她直到6点才到。

Don't get off the bus until it has stopped. 公共汽车停稳后再下车。

I didn't manage to do it until you had explained how. 直到你教我后，我才会做。

区别：1）until可用于句首，而till通常不用于句首。

Until you told me, I had heard nothing of what happened.

直到你告诉我以前，出了什么事我一点也不知道。

3）until when 疑问句中，until要放在句首。例如：

---Until when are you staying? 你呆到什么时候？

--- Until next Monday. 呆到下周一。

注意：否定句可用另外两种句式表示。

4）Not until…在句首，主句用倒装。

Not until the early years of the 19th century did man know what heat is. 直
到19 世纪初，人类才知道热为何物。

Not until I began to work did I realize how much time I had wasted. 直到工作，
才认识到我已蹉跎了许多岁月。

5）It is not until… that….

It was not until I began to work that I realized how much time I had wasted.

6）表示“一……就……”的结构

hardlyscarcely…whenbefore, no sooner…than 和as soon as都可以表示“一……
就……”的意思。

I had hardly scarcely got home when it began to rain. 刚回家，就下起雨来了。

I had no sooner got home than it began to rain.

As soon as I got home, it began to rain.

注意：如果hardly, scarcely 或no sooner置于句首，句子必须用倒装结构。

Hardly Scarcely had I got home when it began to rain.

No sooner had I got home than it began to rain.
