英语时间状语从句用法归纳

1. 引导时间状语从句的从属连词很多,常见的有before, after, when, while, as, since, till, until, as soon as 等。

2. 表示“当…时候”的 while, when, as 的用法区别是:while从句中的谓语动词必须是延续性动词;表示带有规律性的“每当”或当主、从句谓语动词的动作发生有先后时,只能用 when;当表示“一边…一边…”或“随着”时,只能用 as。另外,用于此义的 as 所引导的时间状语从句谓语只能是动作动词,不能是状态动词。如下面一道高考题的答案是 B 而不能是A:

“I’m going to the post office.” “________ you’re there, can you get me some stamps?”

A. As                       B. While                   C. Because                D. If

3. until 在肯定句中通常只连用延续性动词,表示相应动作结束的时间;在否定句中通常连用非延续性动词,表示相应动作开始的时间,意为“直到…才”。如:

If you must go, at least wait till the rain stops. 如果你坚持要走, 至少也要等雨停了再走。

The letter passed from one to another until everyone had read it. 那封信逐一传阅,直到每个人都看过为止。

4. 表示“一…就”除用 as soon as 外,还可用 the minute, the second, the instant, immediately, directly, instantly, no sooner…than, hardly…when 等。如:

I came immediately you called. 你一来电话我就来了。

Hardly had I opened the door when he told me. 我刚开开门,他就告诉了我。

The moment I have finished I'll give you a call. 我一干完就给你打电话。

5. every time, each time, (the) next time, (the) last time, by the time, the first time, any time 等以 time 结尾的词语也可用作连词,引导时间状语从句。如:

Last time I saw him, he looked ill. 上次我见到他时,他好像有病。

Every time I call on him, he is out. 我每次去访问他,他都不在。

You can call me any time you want to. 你随时都可以给我打电话。

Next time you’re in London come and visit us. 你下次来伦敦过来探望我们。

注:其中的every time, each time, any time前不用冠词,(the) next time, (the) last time中的冠词可以省略,而the first time中的冠词通常不能省略。
