2、 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 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 w

3、ent 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 wall3)as 引导从句时侧重主从句动作同时或几乎同时进行，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 breakfast4）when 和 while 还可以是并列连词，意思分别是“就在这时 ”， “然而”。如：I was having a rest on the sofa when the

4、telephone rangThey 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 doingwhen（正在做突然）was/were about to dowhen （刚要做突然）2was/were on the point of doingwhen(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

5、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 had 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

6、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

7、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.33） It is /has been +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，

8、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/scarcely.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

9、, 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。练习题1. It was quiet _ those big trucks started coming through the town.A. before B. after C. until D. unless 2.
