过去进行时讲解与习题
1.概念
过去进行时是表示过去某一时刻或某一时间内正在进行或发生的动作,可以从两个方面来理解：
1 过去某一时刻正在进行或发生的动作。
如： They were playing football at ten
o’clock yesterday morning.
My mother was cooking when I got
home.
I was washing my clothes at this
time yesterday.
2 过去某阶段持续进行的动作。
如：I was staying at home last weekend.
常与过去某一特定的时间状语连用，如
last night, at that time, at 8:00 yesterday,
last Sunday , at this time yesterday, from 7
to 9 last night等。 /
也有时没有时间状语，要通过上下文的暗示来确定用过去进行时。. The students all
worked hard. Everyone knew what he was
working for.
另外，也可用于when/while引导的时间状语从句中。但在复合句中，若主要动作和背景动作是同时发生的，那么主从句都可用过去进行时。
如：It was raining when they left the
hospital.
Jenny was reading while Danny was
writing.
