时间状语从句 就是在复合句中表示主句动作发生时间的状语从句;时间状语从句是所有状语从句中用得最经常的一种,并且用于引导时间状语从句的引导词也比较多,在学习时间状语从句时最重要的是记住这些引导词有哪些,它们的意思怎样等;到底时间状语从句可以用哪些词来引导呢请看下文: 1. 用when引导:when表示“当……时候”;如: Things were different when I was a child. 我小时候情况与现在不同; People breathe more slowly when they are asleep. 人睡觉时呼吸比较缓慢; 2. 用while引导:while表示“当……时候”;如: We must strike while the iron is hot. 我们要趁热打铁; I went swimming while the others played tennis. 我去游泳,其余的人都打网球去了; 注意:while 所引导的时间状语从句中谓语动词必须是持续性的,不能是短暂性的; 3. 用as引导:as表示“当……时候”“随着”;如: He dropped the glass as he stood up. 他站起来时,把杯子摔了; We get wiser as we get old. 随着年岁的增长,我们也变得聪明些了; 4. 用before引导:before表示“在……之前”;如: Turn off the lights before you go to bed. 睡觉前要关灯; Before he went to university he was a worker. 上大学之前他是工人; 5. 用after引导:after表示“在……之后”;如: I will tell you after they leave. 他们走我再告诉你; After you finish the letter show it to me.信写完后给我看看; 6. 用until / till引导:until / till表示“直到……”;如: He waited until she was about to leave. 他等着一直到她准备离开; I watched him until he disappeared in the distance. 我瞧着他直到他在远处消失; 这类句型的主句动词通常只能是,不能是终止性动词;但是,在否定句中,主句动词可以是终止性动词,此时构成not…ntil till…句式,意为“直到……才……”;如: She didn’t marry until she was over fifty. 她直到五十多岁才结婚; We’d better not go until your sister arrives. 我们最好等你姐姐到了再走; 7. 用since引导:since表示“自从……以来”;如:

时间状语从句用法

概念:在复合句中,由时间连接词引导得状语从句叫做时间状语从句。(在复合句中,要注意主句与从句得时态大多都要保持一致。) 1、由when, while, ,just ,just as, as,after, before, since, until, as soon as,引导得时间状语从句。例如: When you think you know nothing, then you begin to know something、 当您以为自己一无所知得时候,您就就是在开始知道一些事物了。 When truth is buried under the ground ,it grows, it chokes, it gathers such an explosive force that on the day it bursts out , it blows up everything with it、 当真理被埋在地下得时候,它在生长,它感到压抑,它蓄存着这么一种爆炸性 力量,一旦冒出,它就会炸破一切! Strike while the iron is hot、趁热打铁。 You can feel the air moving as your hand pushes through it、 当您得手在空气中挥动得时候,您就能感觉到空气在流动。 Our headmaster laughed as she spoke、我们得校长边谈边笑。 主要时态:主现从不现;主过从四过;主将从现。 when, while与as得区别 when引导得从句得谓语动词可以就是延续性得动词,又可以就是瞬时动词;动作既可以与主句得动作同时发生,又可以在主句得动作前后发生。并且when 有时表示“就在那时”。 例如: When she came in, I stopped eating、她进来时,我停止吃饭。(瞬时动词) When I lived in the countryside, I used to carry some water for him、 当我住在农村时,我常常为她担水。(延续性得动词) We were about to leave when he came in、我们就要离开,就在那时她进来 了。 While引导得从句得谓语动作必须就是延续性得,并强调主句与从句得动作同时发生(或者相对应)。并且while有时还可以表示对比。 例如: While my wife was reading the newspaper, I was watching TV、 (was reading就是延续性得动词,was reading与was watching同时发生) 。 I like playing football while you like playing basketball、 我喜欢踢足球,而您喜欢打篮球。(对比) As表示“一边……一边”,as引导得动作就是延续性得动作,一般用于主句与从句动作同时发生;as也可以强调“一先一后。例如: We always sing as we walk、我们总就是边走边唱。(as表示“一边……一边”) As we were going out, it began to snow、当我们出门时,开始下雪了。(as 强调句中两个动作紧接着先后发生,而不强调开始下雪得特定时间)
