八年级英语下unit5语法之过去进行时讲解
一、过去进行时的结构
1、定义：表示过去某一时刻或某一时间段内正在进行或发生的动作。
2、结构：主语+was/ were +动词ing形式
（注：当主语是第一人称单数或第三人称单数用was，其余人称用were）
二、过去进行时的用法
1.表示过去某一时间段内正在进行的动作
（this morning，the whole morning，last night，all night，from 10:00 to12 :00 yesterday，in those days等）
Eg.She was working the whole morning.
表示过去某一时刻正在发生的动作
（at that time， at this time yesterday， at 5 o'clock yesterday 等）
Eg I was washing the dishes at that time.
表示过去某个动作发生时,另一个动作正在进行
(a.与when引导的时间状语从句连用(主句用过去进行时,从句用一般过去时)
(b.与while引导的时间状语从句连用 (主句用一般过 去时,从旬用过去进行时)
4.表示过去某两个延续性动作同时进行
(多与while引导的时间状语从句连用)
【拓展知识】：
过去进行时与频度副词连用（always，often，usually等），表示喜爱、讨厌、埋怨等感彩。
e.g： My mum was always forgetting things. （表示埋怨）
They was always helping children. （表示赞扬）
易混淆点辨析：when和while
1、when的用法：
when意为＂当……的时候＂，可表示时间点或时间段，主句用过去进行时，从句用一般过去时。从句中的谓语动词可以是延续性动词，也可以是短暂性动词。
e.g： I was reading a book when she came into my room.
她走进我房间时，我正在看书。
2、while的用法：
while意为＂当……的时候＂，只表示时间段，从句谓语动词必须用延续性动词。
① 表示过去某个动作发生时,另一个动作正在进行：
主句用一般过去时，从句用过去进行时。
e.g： While Jim was mending his bike, Lin Tao came to see him.
吉姆正在修他的自行车时，林涛来看他了。
② 表示过去某两个延续性动作同时进行：
主句用过去进行时，从句用过去进行时。
e.g：While he was waiting for the bus, he was reading a newspaper.
他边等车边看报纸。（两个动作都是延续性的）
四、过去进行时与一般过去时区分
过去进行时：表示过去某一时刻或某一时间段内正在进行或发生的动作，强调动作正在进行。
一般过去时：表示过去发生的动作或存在的状态，多指动作已经完成。
e.g： I was watching TV this time yesterday.（强调过去这个时间正在看电视）
I watched TV yesterday.（强调昨天看电视，已经看完。）
五、不能用进行时的情况
1、表心理状态、情感的动词：love，hate，like，care，prefer，know等
2、表示存在、状态的动词：appear，exist，remain，stand等。
3、表示感觉的动词：see，hear，feel，smell，sound，taste等。
4、表示人的期待、允诺、拒绝、结束的词：accept，allow，admit，decide，refuse，promise等。
