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。
