【第2篇 小学英语语法总结：过去进行时
过去进行时主要用于：
表示过去某个时刻或阶段正在进行的动作。
e.g. at that time she was working in a pla unit.
那时她在解放军某部工作。
what were you doing this time yesterday?
与这个时态连用的时间状语常用：
at nine o`clock, this time last night, these days, at that time 等。
用 when 引导的时间状语从句表示主句的动作正在进行的时间。
e.g. when he came in, i was reading a newspaper.
注：
1 、 while 引导时间状语从句叙述过去的动作时，从句常用过去进行时。
e.g. i read a magazine while i was waiting for the bus.
2 、 when 用作并列连词，意为'这时'，连接两分句时，第一句多用过去进行时。
e.g. i was reading a newspaper when he came in.
一般过去时与过去进行时的区别：
一般过去时：强调过去某一时间开始或完成的动作。
过去进行时：强调过去某一时间正在进行的动作。
试区别下面两句： we were building a reservoir last winter.
去年冬天我们在修建一座水库。(可能尚未建成) we built a reservoir last winter.
去年冬天我们修建了一座水库。(已经建成)
