在英语中用从句来表示一件事情或行为发生的时间，那么这个从句叫作时间状语从句。时间状语从句在句子中所作的成分是时间状语。
Grammar
1)When/While he was eating his lunch, the doorbell rang.
When I stopped my car, a man came up to me.
2)When you have finished your work, you may have a rest.
小结：while引导的时间状语从句的谓语动词必须是可延续的，而when引导的时间状语从句的谓语动词是可延续的，也可以是表短暂性动作的动词。
小结：从句动作发生在主句动作之前时，只能用 when引导这个从句，而不能用while。
1.连接词when, while的用法区别
before"在……之前"，引导时间状语从句时，表示主句动作发生在从句动作之前。例如：　
after"在……之后"，引导时间状语从句时，表示主句的动作发生在从句的动作之后。例如：
Close the door before you leave the room.
离开房间前关上门。
I went to bed after I finished my homework.做完作业后我就去睡觉了。
2. Before , after用法
意为“自从”，引导时间状语从句.
自从杰克加入足球队以来，他更多地学会了团队合作。
自从他离开家乡，已经有二十年了。
常用于主句是现在完成时+since +从句一般过去时的句式中。
Jack has learned more about teamwork since he joined
the football team.
It has been twenty years since he left his home.
3. since用法
意为 “一……就……”,表示从句动作一发生，主句的动作马上就发生。如果主句是一般将来时，则从句使用一般现在时。
杰克的妈妈太累了她一躺再床上就睡着了。
Jack’s mother was so tired that she fell asleep as soon as she lay down on the bed.
4. as soon as 用法
主句为肯定句时，主句谓语动词必须是延续性动词，该动词所表示的动作或状态一直延续到
until, till从句所表示的时间为止。
She kept on asking questions until the bell rang.
她一直问问题，直到铃声响了。
5.until/ till用法
主句为否定句时，主句谓语动词是非延续性动词，该动词所表示的动作在until/till 从句表示的时间开始发生。先翻译从句，后翻译主句，译为“直到……才……”
The girl didn’t go to bed until she finished her homework.这个女孩直到完成她的家庭作业后才上床睡觉。
5.until/ till用法
after as soon as since until while
