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。
