【重点语法】
过去进行时
含义及构成过去进行时表示过去某一时刻或某一段时间正在进行或发生的动作，
其结构为：was/were+doing。
用法：
①表示过去某一段时间内正在进行的动作。
如：We were having classes all that day.那天我们整天都在上课。
②表示过去某一时刻正在进行或发生的动作。与过去某一特定的时间状语连用，常见的有：at 3 o’clock yesterday afternoon, in those days, at this time yesterday等。
③表示过去一个动作发生时，另一个动作正在进行，持续时间长的动作用过去进行时，常用在while引导的时间状语从句中。
when与while在引导从句时的区别
用when引导的状语从句表示时间，说明一个动作发生时，另一个动作正在进行，也可表示正在进行某一动作时，另一动作发生了。
如：The students were drawing pictures when the teacher came in.当老师进来时，学生们正在画画。
My pen dropped on the ground when I was walking in the park.当我正在公园散步时，我的钢笔掉在了地上。
用while引导的从句一般用过去进行时，表示正在进行某个动作时，发生了另一个动作，这时主句用一般过去时。如：While he was reading, the telephone rang.当他正在看书时，电话铃响了。
过去进行时与一般过去时的区别
过去进行时强调某一动作是在过去某时正在进行，一般用到的动词是表示具体行动，动作可延续的，同时用到的时间状语表示的范围要小且具体。而一般过去时对谓语动词没有什么限制，用到的时间状语范围不受限制，一般过去时着重表示在过去做过，基本上是一个结束了的动作。表过去状态，抽象，不表具体动作行为的动词不用过去进行时，但可以用一般过去时。
如：Mr. Green was mending his daughter’s bike this morning.（强调动作正在进行）
Mr. Green mended his daughter’s bike this morning.（表示动作做过，并结束了）

when引导的时间状语从句与瞬间性动词连用时，用一般过去时，主句用过去进行时。
I was waiting for the bus when it began to rain heavily.
3.While I was making my breakfast, my brother was listening to the radio.当我在做早饭的时候，我弟弟正在听收音机。(4b)
