(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 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 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）was/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 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 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，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)2条件状语从句常见的从属连词有：if, unless, as/so long as , as/so far as, on condition that , in case(万一) , the more, the more等。如：As/So far as I can see ( am concerned), it will be impossible for them to finish the task.The more books you read, the happier you will feel(前面为从句)3原因状语从句常见的从属连词有：because, since, now that , as等。注意because, since, as的区别：）why的语气最强，它引导的从句比主句更重要，从句的位置可前可后；例外回答why的问句必须使用because。如：-Why were you absent from the meeting yesterday?-Because I was ill.2)since和now that意思是“既然”，语气仅次于because,从句的位置一般在前。如：Since everybody is here, lets begin our meeting3)as的语气比since更弱，意思是“由于”，从句的位置可前可后。如：As you didnt turn up at yesterdays get-together, we missed you very much）*for也有“因为”之意，但for是并列连词常用来来补充说明原因或用来表示推断的依据，前面常带逗号。如：It must have rained last night, for the ground is wet4让步状语从句常见的从属连词有：though, although, as, even if / though, no matter wh-， wh-ever, whetheror等。如：However late/No matter how late he is, his family will wait for him to have dinner together.Child as he is, he knows a lot.
