過去進(jìn)行時(shí)和一般過去時(shí)的區(qū)別：
一、過去進(jìn)行時(shí)和一般過去時(shí)的區(qū)別在于：一般過去時(shí)敘述舊事，過去進(jìn)行時(shí)描述背景。我們先來看看一般過去時(shí)的用法：
1、敘述過去狀態(tài)、動(dòng)作或事件，例如：
He went to Beijing the other day.（帶具體時(shí)間）
2、表示過去的習(xí)慣一般用would和used to與過去時(shí)連用，would 表間斷性不規(guī)則的習(xí)慣，常帶頻率時(shí)間used to 表一貫性有規(guī)律的習(xí)慣，例如：
1）They used to meet and would sometimes exchange one or two words.
2）He smoked a lot two years ago. （過去行為）
Would 用于文中不用于句首，只表過去習(xí)慣。Used to 表今昔對比的含義，敘述習(xí)慣動(dòng)作可與would 換用。例如：
1）When he was a boy ，he would often go there . （敘述過去）
2）She isn't what she used to be. （今昔對比）
3、表示狀態(tài)時(shí)一般只用used to
Tom used to be fat /There used to stand a tree there. （狀態(tài)）
4、was （were） used to +ving表示“合適于，適應(yīng)于…..”
1）He used to work at night . （“習(xí)慣”表經(jīng)常）
2）He was used to working at night. （“習(xí)慣”表適應(yīng)）
5、表示過去的經(jīng)歷，平行動(dòng)作，依此事件用一般過去時(shí)。
He sat there and listened to the radio.（依此發(fā)生）
6、表示客氣委婉的語氣，用于情態(tài)動(dòng)詞，助動(dòng)詞和want ， wonder ， hope 等
How did you like the film？ / Could you help me？

二、過去進(jìn)行時(shí)
1、表示在過去某階段或某一時(shí)刻正在發(fā)生
What were you doing at 8：30 last night？（過去某時(shí)刻正在發(fā)生）
2、短暫性動(dòng)詞用過去進(jìn)行時(shí)表示按計(jì)劃、打算
During that time he was going with us.（表示打算）
3、與always ，often ，usually 等連用表喜愛，討厭等感情色彩。
He was always Changing his mind.

三、過去進(jìn)行時(shí)與一般過去時(shí)的區(qū)別
1、進(jìn)行時(shí)表某一行為的“片斷”一般時(shí)表示行為的“整體”和存在的狀態(tài)。
I was reading the book at that time. （未讀完，“讀”的片段）
I read the book yesterday. （已讀完，表整個(gè)“讀”）
2、一般持續(xù)時(shí)間狀語多與進(jìn)行時(shí)連用
It was raining all night.（優(yōu)先用was raining ，rained 為持續(xù)動(dòng)詞，故也可使用）
He was writing a letter the whole of afternoon. （短暫動(dòng)詞與持續(xù)時(shí)間連用，表反復(fù)，連續(xù)發(fā)生，不可用一般過去時(shí)）
