题目

过去进行时的用法（举例子最好）

答案

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.
What were you doing at nine last night?
昨晚九点时,你在做什么?
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.
（当）我在擦窗户的时候,我弟弟在拖地.
Some students were playing football,while others were running round the track.

We were walking along the river when（suddenly） It rained.
我们沿着河边散步,突然下起雨来.
They were watching TV when the lights went out.
停电时,他们刚好在看电视.（注意：同上例）
3 过去进行时表示过去将来的动作
现在进行时可以表示将来的动作,同样,过去进行时也可以表示从过去某时间看来将要发生的动作.常用在间接引语中.
She went to see Xiao Li.
He was leaving early the next morning.
她去看小李.他第二天一早就要离开此地了.
She asked him whether he was coming back
to lunch.
她问他晚饭是否准备回来吃.
4 过去进行时和一般过去时的区别
过去进行时表示过去某时正在进行的动作,而一般当两个延续动作同时并行时,二者都可用过去进行时表达.
此时的when是连词,与上面第2.3例不同,只能用于句子中间.过去时则表示一个完成的动作.也就是说用一般过去时,只是表示有过这件事；用过去进行时,则强调了动作的连续性.

Li Ming was washing the dishes.
