　　3-2 過去進(jìn)行式

　　過去進(jìn)行式和現(xiàn)在進(jìn)行式有點(diǎn)類似，只是verb to be要用過去式的?？墒怯幸稽c(diǎn)不同，過去進(jìn)行式，很少單獨(dú)用的，而常和另一句子一齊用。舉例來說以下的中文句子：

　　我昨天去看你的時(shí)候，你正在打籃球，如譯成中文，就是:

　　You were playing basketball when I went to see you yesterday.

　　以下是典型的過去進(jìn)行式用法

　　I was watching TV when you came to see me.

　　They were dancing when the teacher came in.

　　They were singing in the station when the train arrived.

　　Mr. Brown was cleaning his house when his son came home.

　　總而言之，過去進(jìn)行式通常牽涉到幾件事，這兩件事同時(shí)發(fā)生，其中一件事用過去式，另一件事用過去進(jìn)行式
