如：As a young man, he was active in sports.连接词when,while,as的用法区别1、while引导的时间状语从句的谓语动词必须是可持续的，而when引导的时间状语从句的谓语动词既可以可持续的，也可以是表短暂性动作的动词。
When\While he was eating his breakfast,he heard the door bell rang.When I stopped my car,a man came up to me.(while不可用)2、从句动作发生在主句动作之前时，只能用when 引导，不可用while\as, 如：When you have finished your work,you may have a rest3、表示“随着……”,连词用as,不用when\while,如：As the election approached,the violenve got worse.4、如果主句表示的是短暂性的动作，从句用延续性动作的进行时态表示一段时间内正在进行的动作时，三者可互相交换使用。
如：When\While\As I was walking down the street,I came across an old friend of mine.till,until和not…until用法1、until\till引导时间状语从句用于肯定句中时，主句的动词时延续性动词，表示动作或状态一直持续到until\till所表示的时间，意为“某动作一直持续到某时间点才停止”，译为“直到…为止”。
