1樓的對的,我估計你們現在在學過去進行時吧
一、 概念和用法：過去進行時表示在過去某一時刻或某一段時間內進行或發生的動作.其形式爲was /were + V-ing.常與表示過去的時間狀語連用,如：last night,last Saturday等；或者與when,while,as引導的過去時間狀語連用.例如：
We were watching TV from seven to nine last night.昨天晚上七點到九點的時候我們在看電視.
What was he researching all day last Sunday?上周日他一整天都在研究什麼?
二、 過去進行時可以表示在過去某個時間點發生的事情.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麼?(介詞短語表示時間點)
When I saw him he was decorating his room.當我看見他的時候他正在裝飾房間.(when從句表示時間點)
三、 在複合句中,如果主要動作和背景動作都是延續的或同時發生的,那麼主從句的動詞都可用過去進行時.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.(兩個動作同時進行)
四、 通常不能用於過去進行時的動詞主要有：agree,be,believe,belong,care,forget,hate,have(擁有),hear,know,like,love,mean,mind,notice,own,remember,seem,suppose,understand,want,wish等.例如：
誤：I was knowing the answer.
正：I knew the answer.我知道答案.
誤：I wasn『t understanding him.
正：I didn『t understand him.我不明白他的意思.
句型：
肯定句：主語+was/were+doing+其它
否定句：主語+was/were+not+doing+其它
一般疑問句及答語：Was/Were+主語+doing+其它
特殊疑問句：特殊疑問詞+was/were+主語+doing+其它
