学习时间状语从句的几点注意

 

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:

He waited until she was about to leave. 他等着一直到她准备离开。

I did not begin to work till he had gone. 他走了后我才开始工作。

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 she arrived when it began to snow. 她刚到就下起雪来了。

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(www.hxen.com):

Next time you come in, please close the door. 下次你进来,请关门。

He didn’t tell me anything the last time I saw him. 上次我见到他时他什么也没告诉我。

By the time I got home, she had already gone to bed. 我到家时她已睡觉了。
