4、维也纳的。.语法预习导学一、时间状语从句1when,while,as引导的时间状语从句(1)当从句谓语动作进行时间较长时用while,而不用as和when。They slept while we kept watching over them.我们监视他们的时候,他们睡着了。(2)while不能与表示瞬间性的动词连用。I was quite happy as/when I found my lost watch.当找到丢失的手表时,我真的很高兴。(3)as和while都可以与持续性动词连用,表示两个动作同时发生,但前者强调的是持续的全过程,后者强调的是动作的同时性。因此把as译成“正当”或“与
5、同时”;而把while译成“在过程中”或“在期间”。It often changes in speed and direction while it is moving.它在运动过程中经常改变速度和方向。It changes in speed and direction as it moves.它在运动时,改变了速度和方向。(4)when和as都可以表示两个动作的先后顺序,而while却不能。When/As the clock struck six,Tom got up.当六点的钟声敲响的时候,汤姆起床了。(5)when可以作并列连词表示“这时(突然)”。He was working on a
6、 design when his friend arrived.他正在搞设计,这时他的朋友到了。2as soon as,immediately,directly,once,no sooner.than,hardly.when引导的时间状语从句,表示“一就”。I came directly I got your message.我一得到你的消息,就来了。注意当no sooner.than,hardly.when中的no sooner,hardly置于句首时,主句部分倒装。No sooner had Jack seen me than he left the classroom.Hardly ha
7、d Jack seen me when he left the classroom.杰克一看见我就离开了教室。3the moment,the day,next time,last time,every time,each time等词引导时间状语从句。He came to the spot the moment he heard of the accident.他一听说这起事故就赶到了现场。Every time I travelled by boat,I got seasick.每次我乘船旅行都会晕船。4till,until引导的时间状语从句We will stay here till/unt
8、il it stops raining.我们将一直呆在这里直到雨停。主句有否定意义时,till/until含有before的意思,通常译为“直到才”。John did not announce the news till he was sure of it.约翰直到对这个消息确信无误时才宣布。not until放在句首时,主句的主语和谓语要倒置,表示加强语气。Not until the rain stopped did we leave there.直到雨停了我们才离开那儿。5since引导的时间状语从句I have been in Beijing since you left.自从你离开以来
9、,我一直在北京。注意since引导的从句的谓语动词可以是延续性动词,也可以是瞬间动词。一般情况下,从句谓语动词用一般过去时,而主句的谓语动词用现在完成时。但在“It is时间since从句”的句型中,主句多用一般现在时。二、过去完成时过去完成时表示的是“过去的过去”发生、进行或完成了的动作。使用过去完成时,一般要有可以与之比较的“过去时间点”。过去完成时主要用在以下场合:1过去完成时常与by,by the end of,by the time引导的状语连用。In Germany,over 50% of the trees had been damaged by (the year) 1896.
10、在德国,到1896年止,全国已经有过半数的树木被毁坏。2表示从过去某一时刻开始,一直延续到过去另一时刻的动作或状态。She said she had worked in that factory.她说她在那家工厂工作过。3当一个由before,after,as soon as等连词引导的从句所表示的动作和主句的动作先后、紧接着发生时,由于这些连词本身已经说明两个动作发生的先后关系,因此从句和主句的谓语动词均可用一般过去时。He left the room after he (had) turned off the light.他把灯关上之后离开了房间。4过去完成时也用于hardly.when.
11、;no sooner.than.等一些固定句型中。He had hardly arrived when it began to snow.他刚到,天就开始下雪。5有些动词,如think,hope,expect,intend,mean,suppose,want等,在用过去完成时时,可以表示过去未实现的愿望和打算。They had wanted to come,but they were too busy.他们本来是要来的,但他们太忙了。6在it was the first time that句型中,that分句的动词常用过去完成时。It was the first time that he ha
