2、oing his homework, the telephone rang.As he walked along （沿着走）the lake, he sang happily.He had learned a little Chinese before he came to China.After he finished middle school, he went to work in a factory.(2) 在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如：I ll ring you up as soon as I get to New York.I will

3、tell him everything when he comes back.He won t believe it until he sees it with his own eyes.(3) 在带有 till 或 until 引导的时间状语从句的主从复合句里如果主句用肯定式，其含义是 “一直到 时 ”，谓语动词只能用延续性动词。如果主句用否定式，其含义是“直到 才 ” , 在“ 以前不 ” , 谓语动词可用瞬间动词。例如：The young man read till the light went out（熄灭）.Let s wait until the rain stops.We won

6、例如：He didn t cometoschool because he was ill. As it is raining, we shall not go to the zoo. Since you can t answer the question, I ll ask someone else.精品资料欢迎下载(2) bcause since as forbecause表示直接原因， 语气最强。Because 引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。As和since 语气较弱，一般用来表示明显的原因。由as 和since 引导的原因状语从居多放在句

7、首。 for 并列连词，正式，例如：- Why aren tyou going there?- Because I don t want to.As he has no car, he can t get there easily.Since we have no money, we can t buy it.(3)because 和 so 不能 同用在一个句子里。4. 结果状语从句(1) 结果状语从句由 so that, such that, soat 引th导。例如： He is so poor that he can t buy a bike for his son.

11、to miss it.*(3) 如果名词前由many, much, little, few等词修饰时，只能用so,不用such。例如：Soon there were so many deer that they ate up all the wild roses.He has so little time that he cango to the cinemat（去看电影）with you.5. 比较状语从句比较状语从句通常由as+原级 as, 比较级+ than 等连词引导。例如：Tom runs faster than John does.This classroom is as big
