英語時間狀語從句用法歸納

1. 引導時間狀語從句的從屬連詞很多，常見的有before, after, when, while, as, since, till, until, as soon as 等。

2. 表示“當…時候”的 while, when, as 的用法區別是：while從句中的謂語動詞必須是延續性動詞；表示帶有規律性的“每當”或當主、從句謂語動詞的動作發生有先后時，只能用 when；當表示“一邊…一邊…”或“隨著”時，只能用 as。另外，用于此義的 as 所引導的時間狀語從句謂語只能是動作動詞，不能是狀態動詞。如下面一道高考題的答案是 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 在肯定句中通常只連用延續性動詞，表示相應動作結束的時間；在否定句中通常連用非延續性動詞，表示相應動作開始的時間，意為“直到…才”。如：

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

The letter passed from one to another until everyone had read it. 那封信逐一傳閱，直到每個人都看過為止。

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

I came immediately you called. 你一來電話我就來了。

Hardly had I opened the door when he told me. 我剛開開門，他就告訴了我。

The moment I have finished I'll give you a call. 我一干完就給你打電話。

5. every time, each time, (the) next time, (the) last time, by the time, the first time, any time 等以 time 結尾的詞語也可用作連詞，引導時間狀語從句。如：

Last time I saw him, he looked ill. 上次我見到他時，他好像有病。

Every time I call on him, he is out. 我每次去訪問他，他都不在。

You can call me any time you want to. 你隨時都可以給我打電話。

Next time you’re in London come and visit us. 你下次來倫敦過來探望我們。

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