过去进行时
过去进行时的用法
表示过去某时正在进行的状态或动作。例如:
I was watching TV when she came to see me.
We were doing our homework at 9:00 yesterday evening.
【注意】
过去进行时和一般过去时都是过去发生的事情,但过去进行时侧重表示过去某一时刻正在进行的动作或所处的状态,强调动作的连续进行,而一般过去时则表示单纯的过去事实,例如:
They were building a house last month. (上个月正在建造,建造好与否不知)
They built a new house last month. (上个月建造好了,动作已经完成)
肯定句He was playing basketball at 4:00 yesterday afternoon.
否定句He was not watching TV when I came to see me.
一般疑问句Were you having supper when he came home?
特殊疑问句What were you doing at that time?What was he doing at 8:00 this moring?
