(2)过去进行时则表示所说的事情在过去某一时刻或一段时间内正在进行，而没有结束。它可用于以下情况：
在无时间状语的情况下，它表示逐渐的发展或事件发生的背景。
The wind was rising.风越刮越大。
与某一具体时间/刻连用，它表示某一动作在那个时刻以前已开始，并可能要延续到那一时刻以后。
I was watching TV (at) this time yesterday.昨天的这个时候，我正在看电视。
过去进行时经常与一般过去时配合使用，这时，过去进行时通常作为一般过去时的时间背景。
We were all sleeping soundly when the earthquake happened. 地震发生时，我们都睡得正香。
如果两件事都同时在进行，也可都用过去进行时来表示。
Some were carrying water while others were watering trees.有的在提水，有的在浇树。
过去进行时与always连用，用来表示一个不断重复的过去动作，表达说话人赞赏或厌恶的情感。
He was always ringing me up. 他老是给我打电话。
正如现在进行时可以表示一个明确的将来计划一样，过去进行时也可以表示这种发生在过去的将来。
Mr. Smith was busy packing, because he was leaving for London that night.
史密斯先生正忙着收拾行李，因为那天晚上他要动身去伦敦。
注意：同样一件过去的事情，用以上两种不同的时态表过没内涵：过去时强调动作的结束；而过去进行时，则强调动作的延续性。例如：
I cleaned the house this morning.上午我打扫了房间。
I was cleaning the house this morning.上午我一直在打扫房间。

答案与分析
【解析】（1）表示过去终止的动作；（2）when she saw it 表示“时间点”，指过去进行的动作；（3）but I don’t know whether she has finished it. 暗示“过去的动作并未结束”。答案为：(1) A; (2) A: (3)C。
【说明】一般过去时和过去进行时的区别是考试的热点。简单归纳起来，应记住两点：（1）一般过去时表示一个过去已完成的动作，强调动作的结束；（2）过去进行时表示过去正在进行的动作，强调动作的延续。应用时，注意找到对照时间，分辨是指时间还是终止时间。
