1 过去进行时主要表示过去某个时刻或某一阶段正在进行的动作,常和表示过去时间的状语then,at this(that) time, yesterday,at nine,last night等连用。但在不少情况下,没有表示时间的状语,这时需要通过上下文来表示。

I called you yesterday afternoon but there was no answer.

昨天下午我打电话给你,但是没有人接电话。

I was visiting a friend of mine most of the afternoon.

我昨天下午大部分时间,都在一个朋友家里。

2 当两个一长一短的动作在过去某时间同时发生时,用过去进行时表示较长的动作。过去进行时可用于主句,也可用于从句。

It was raining hard when I left my office.

当我离开办公室时,雨下得正大。

When you called,I was eating.

你打电话时,我正在吃饭。

When I was cleaning the windows, my brother was sweeping the floor.
