Language practice Presentation 由上一模块我们已经知道，过去进行时表示过去某一时刻或时段正在进行或持续的动作。过去进行时还可以和when, while 或as引导的过去时间状语从句连用构成复合句。下面是when和while从句与过去进行时连用的几种情况。 1．when所引导的时间状语从句既可以指时间点，也可以指时间段；while所引导的时间状语只指时间段。因此，在when引导的时间状语从句中，动词可以是终止性动词，也可以是延续性动词；而在while从句中，动词必须是延续性动词。 They arrived while/when we were having dinner. 我们吃饭的时候他们到了。 2．由when引导的时间状语从句，如果主句用过去进行时，从句应该用_____，表示一个动作正在进行的时候，另一个动作(突然)发生了，强调后一动作发生的突然性。 We were talking when the teacher came in. 我们正在说话时，(突然)老师进来了。 一般过去时 3．当从句和主句的动作都是延续性的或同时发生时，即主从句都用过去进行时的时候，多用_____引导。 They were singing while we were dancing. 他们在唱歌，我们在跳舞。 while Complete the sentences with when or while. 1 1 He was listening to music _____ he was riding his bike. 2 I was waiting at the lights _____ I saw the boy fall off his bike. 3 I was walking in the street _____ an accident happened. 4 The driver was talking on his mobile phone _____ he was driving. while when when while Look at what Tony did last Saturday.
