连接词when的用法小结 1. when引导的时间状语从句的谓语动词可以是可延续 的，也可以是表短暂性动作的动词，可用于主句和从句 动作同时发生或从句动作先于主句动作。如： When the film ended, the people went back. When I lived there, I used to go to the seashore on Sundays. 2. 可用作并列连词，其意义为“那时，这时”，相当于 and at this/that time。常用于下列句式： Somebody was doing something/was about to do sth./was on the point of doing sth. when… (刚要……这时突然……) 3. 还可以表示原因“既然”，相当于since; considering that。如： It was foolish of you to take a taxi when you could easily walk there in five minutes .
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。如：When/While he was eating his breakfast, he heard the doorbell ring. When I stopped my car, a man came up to me. (不可用 while) 2．从句动作发生在主句动作之前时，只能用when引导这个 从句，不可用as或while。如： When you have finished your work, you may have a rest. 3．表示“随着……”，连词用as，不用when或while。如： As the election approached, the violence got worse. 4．如果主句表示的是短暂动作，而从句用延续性动作的进行 时态表示在一段时间内正在进行的动作时，when, while 与as 可互换使用。如： When/While/As I was walking down the street, I came across an old friend of mine.
