2、 as(只要)原因 As,because,since,as/so long as(既然,因为)地点 Where 目的 So that(为了),in order that 结果 So that(方便),sothat,suchthat 让步 though,although,even if,however 方式 As 比较 than,(not)as as 1.时间状语从句 时间状语从句 常见的从属连词有:(注意其汉语意义)when,while,as,before,after,since,until(till)once as soon as,the moment,the minute,immediat
3、ely,directly,each/every time,the first time,the last time,next time,by the time,whenever 等。例如:Every/Each time I was in trouble,he would come to my help.I thought her nice and honest the first time I met her.注意:(1)when,while,as 的区别:1)when 引导从句时,主从句的动作有先有后,也可以同时进行,从句的动作可以是持续性的,也可以是短暂的。如:When I got to
4、the airport,the plane had already taken off.(主先从后)(短暂性)When I lived there,I used to go to the seaside on Sundays.(同时)(持续性)When the movie ended,the people went back.(从先主后)2)while 侧重主从句动作的对比,且从句的动词必须是持续性的。如:While we were chatting she was looking at the time table on the wall 3)as 引导从句时侧重主从句动作同时或几乎同时进行
5、,从句的动作可以是持续性的,也可以是短暂的。如:Sometimes I watch TV as I am having breakfast 4)when 和 while 还可以是并列连词,意思分别是“就在这时”,“然而”。名师总结 优秀知识点 如:I was having a rest on the sofa when the telephone rang They were surprised that a child should work out the problem while they couldnt.注:并列连词 when 常用与以下句型中:was/were doing when
6、(正在做突然)was/were about to do when(刚要做突然)was/were on the point of doing when(刚要做突然)had just donewhen.(刚一就)Hardly/Scarcely haddonewhen(刚一就)(2)before 引导从句时,词义非常灵活,注意下列句子中的 before 的词义:1.Before I could get in a word,the tailor had measured me.(还没来得及就)2.We hadnt run a mile before he felt tired.(还没就)3.We ha
7、d sailed 4 days before we saw land.(才)4.Please write it down before you forget it.(趁还没就)(3)till(until)和 nottill(until)1)till(until):主句谓语动词必须是持续性的,意思是“到为止“如:He remained there till/until she arrived.2)nottill(until):主句谓语动词必须是短暂性的,意思是“直到才”如:She wont go to bed till/until he returns home.3)notuntil 还有强调式
8、和倒装式:强调句:It is not until he returns home that she will go to bed.倒装句:Not until he returns home will she go to bed.(4)几个极易混淆的时间状语从句:1)It was+时间点+when(当的时候时间是)It was 5 am when we arrived at the village.2)It was/will be+时间段+before(没过就过了才)It was/will be two weeks before we met/meet again.3)It is/has bee
9、n+时间段+since(自从以来有)It is/has been 3 years since we last met.突破点:一看 be 动词的时态,二看时间段还是时间点。注意:在“It is/has been+时间段+since”句型中,从句的动词必须是短暂性的,如果是延续性的动词,时间要从从句的动作结束时算起。如:It is 3 years since I smoked.(我戒烟有三年了)补充:as soon as,immediately,directly,instantly,the moment,the minute,the instant,no soonerthan,hardly/sc
10、arcely.when.和 once 这些从属连接词引导的从句都表示从句的动作一发生,主句的动作随即就发生,常译为“一就”。从句中一般时态代替将来时态。every time,each time,next time,the first time,any time,all the time等名词短语用来引导时间状语从句,表示“每当.,每次.;下次”等。1.It was quiet _ those big trucks started coming through the town.句目的状语从句让步状语从句地点状语从句用来修饰主句中的动词副词和形容词的从句叫状语从句根据其含义状语从句可分为时间状语
