(2)結(jié)構(gòu):was/were +doing (現(xiàn)在分詞)
(3)用法:
① 過去進(jìn)行時表示過去某段時間內(nèi)持續(xù)進(jìn)行的動作或者事情。常用的時間狀語this morning, the whole morning, all day yesterday, from nine to ten last evening, when, while例如:

② 過去進(jìn)行時可以表示在過去某個時間點發(fā)生的事情。時間點可以用介詞短語.副詞或從句來表示。如:
What was she doing at nine o'clock yesterday?昨天晚上九點她在做什么?(介詞短語表示時間點)
When I saw him he was decorating his room.
當(dāng)我看見他的時候他正在裝飾房間。(when從句表示時間點)
➂ 在復(fù)合句中,如果主要動作和背景動作都是延續(xù)的或同時發(fā)生的,那么主從句的動詞都可用過去進(jìn)行時。
例如:
While he was waiting for the bus, he was reading a newspaper.他邊等車邊看報。(兩個動作都是延續(xù)的)
He was cleaning his car while I was cooking.他擦車時我在做飯。(兩個動作同時進(jìn)行)
