　　3-2 過去進行式

　　過去進行式和現在進行式有點類似，只是verb to be要用過去式的。可是有一點不同，過去進行式，很少單獨用的，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行式用法

　　I was taking a bath when you called.

　　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，過去進行式通常牽涉到幾件事，這兩件事同時發(fā)生，其中一件事用過去式，另一件事用過去進行式
