过去进行时和一般过去时的区别:
一、过去进行时和一般过去时的区别在于:一般过去时叙述旧事,过去进行时描述背景。我们先来看看一般过去时的用法:
1、叙述过去状态、动作或事件,例如:
He went to Beijing the other day.(带具体时间)
2、表示过去的习惯一般用would和used to与过去时连用,would 表间断性不规则的习惯,常带频率时间used to 表一贯性有规律的习惯,例如:
1)They used to meet and would sometimes exchange one or two words.
2)He smoked a lot two years ago. (过去行为)
Would 用于文中不用于句首,只表过去习惯。Used to 表今昔对比的含义,叙述习惯动作可与would 换用。例如:
1)When he was a boy ,he would often go there . (叙述过去)
2)She isn't what she used to be. (今昔对比)
3、表示状态时一般只用used to
Tom used to be fat /There used to stand a tree there. (状态)
4、was (were) used to +ving表示“合适于,适应于…..”
1)He used to work at night . (“习惯”表经常)
2)He was used to working at night. (“习惯”表适应)
5、表示过去的经历,平行动作,依此事件用一般过去时。
He sat there and listened to the radio.(依此发生)
6、表示客气委婉的语气,用于情态动词,助动词和want , wonder , hope 等
How did you like the film? / Could you help me?

二、过去进行时
1、表示在过去某阶段或某一时刻正在发生
What were you doing at 8:30 last night?(过去某时刻正在发生)
2、短暂性动词用过去进行时表示按计划、打算
During that time he was going with us.(表示打算)
3、与always ,often ,usually 等连用表喜爱,讨厌等感情色彩。
He was always Changing his mind.

三、过去进行时与一般过去时的区别
1、进行时表某一行为的“片断”一般时表示行为的“整体”和存在的状态。
I was reading the book at that time. (未读完,“读”的片段)
I read the book yesterday. (已读完,表整个“读”)
2、一般持续时间状语多与进行时连用
It was raining all night.(优先用was raining ,rained 为持续动词,故也可使用)
He was writing a letter the whole of afternoon. (短暂动词与持续时间连用,表反复,连续发生,不可用一般过去时)
