举例
时间状语从句
1.时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。
例：It was raining hard when I got to school yesterday.
While he was doing his homework, the telephone rang.
As he walked along 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：I’ll ring you up as soon as I get to New York.
I will 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，结构是not...until，其含义是“直到……才……”，谓语动词可用瞬间动词。
例：Let’s wait until / till the rain stops.
We won’t start until Bob comes.
4.when , while, as的区别和联系：
（1）在when引导的时间状语从句中，动作可以是表示延续的（长动作），也可以是表示瞬间的（短动词）；
（2）while引导的从句中，动作一定是表示延续的（长动词）；
（3）as“当…….时；一边….一边…..”,引导的时间状语从句，强调主句的动作与从句的动作同时发生，when与while也有此用法；
（4）when和as常表示从句动作先于主句动作，有时when还可以表示从句动作在主句动作之后；
例：I was watching TV when Tom came in.
Tom came in while I was watching TV.
As she was dancing, she was singing.
It’s getting colder and colder as the winter comes.
注：while 除了可以做“正当...时候”之意，还可以表示转折，意思是“然而”。还可以作名词讲，“片刻之意”。
例：Some people waste food while others haven't enough.有些人浪费粮食,然而有些人却吃不饱。
I haven’t seen her for a long while. 我好久没有看见她了。
（5）since的考查
since引导的时间状语从句，表示主句动作开始的时间，译为“自…以来”。主句常用现在完成时，从句用一般过去时。此外也有： It has been…since从句；It is +一段时间+since从句。
例：He has taught us Maths since he came here.
It’s ten years since I worked in the hospital.
Where have you been since I saw you last?
注：对 since 引导的时间状语提问要用how long。
