時間狀語從句就是在復合句中表示主句動作發生時間的狀語從句。時間狀語從句是所有狀語從句中用得最經常的一種,并且用于引導時間狀語從句的引導詞也比較多,在學習時間狀語從句時最重要的是記住這些引導詞有哪些,它們的意思怎樣等。到底時間狀語從句可以用哪些詞來引導呢?請看下文:
1. 用when引導:when表示當時候。如:
Things were different when I was a child. 我小時候情況與現在不同。
People breathe more slowly when they are asleep. 人睡覺時呼吸比較緩慢。
2. 用while引導:while表示當時候。如:
We must strike while the iron is hot. 我們要趁熱打鐵。
I went swimming while the others played tennis. 我去游泳,其余的人都打網球去了。
注意:while 所引導的時間狀語從句中謂語動詞必須是持續性的,不能是短暫性的。
3. 用as引導:as表示當時候隨著。如:
He dropped the glass as he stood up. 他站起來時,把杯子摔了。
We get wiser as we get old. 隨著年歲的增長,我們也變得聰明些了。
4. 用before引導:before表示在之前。如:
Turn off the lights before you go to bed. 睡覺前要關燈。
Before he went to university he was a worker. 上大學之前他是工人。
5. 用after引導:after表示在之后。如:
I will tell you after they leave. 他們走我再告訴你。
After you finish the letter show it to me.信寫完后給我看看。
6. 用until / till引導:until / till表示直到。如:
He waited until she was about to leave. 他等著一直到她準備離開。
I watched him until he disappeared in the distance. 我瞧著他直到他在遠處消失。
這類句型的主句動詞通常只能是延續性動詞,不能是終止性動詞。但是,在否定句中,主句動詞可以是終止性動詞,此時構成notntil [till]句式,意為直到才。如:
She didnt marry until she was over fifty. 她直到五十多歲才結婚。
Wed better not go until your sister arrives. 我們最好等你姐姐到了再走。
7. 用since引導:since表示自從以來。如:
We have known each other since we were children. 我們從小認識。
Theyve moved twice since they got married. 他們結婚后已搬了兩次家。
這類句子的主句通常用現在完成時。但是,當主句表示一段時間時,可用一般現在時代替現在完成時。如:
Its a long time since we met last. 好久沒見面了。
How long is it since you came in London? 你來倫敦有多久了?
8. 用as soon as引導:as soon as表示一就。如:
The boys ran off as soon as we appeared. 我們一來,孩子就都跑了。
He started as soon as he received the news. 他一接到消息就出發了。
表示一就這一意思的連詞,除as soon as外,還可用the moment, the minute, the instant等。如:
I want to see him the minute he arrives. 他一來到我就要見他。
The moment I saw him I knew there was no hope. 我一看到他就知道沒希望了。
9. 用every time等引導:any time, each time, every time, the first time, the last time, the next time等有時也可用連詞,引導時間狀語從句,分別表示任何時候每次第一次最后一次下次等。如:
You can call me any time you want to. 你隨時都可以給我打電話。
Each time I went there, I saw him working. 我每次去那兒都看見他在工作。
Every time I call on him, he is out. 我每次去訪問他,他都不在。
Next time you come in, please close the door. 下次你進來,請關門。
10. 間狀語從句的時態:當主句為將來時態或含有將來意義時,時間狀語從句習慣上要用一般現在時表示將來意義,而不能直接使用將來時態。如:
■趁早動手,免得忘了。
誤:Do it before you will forget.
正:Do it before you forget.
before引導的時間狀語從句不能直接使用將來時態,而通常用現在時表示將來意義。
