1、 过去进行时和一般过去时的区别1一般过去时叙述旧事，过去进行时描述背景。、一般过去时）叙述过去状态、动作或事件He went to Beijing the other day.（带具体时间）表示过去的习惯a) would ,used to 与过去时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They used to meet and would sometimes exchange one or two words.He smoked a lot two years ago. （过去行为）b) Would 用于文中不用于句首，只表过去习惯。Used to
2、表今昔对比的含义，叙述习惯动作可与 would 换用。When he was a boy , he would often go there . （叙述过去）She isnt what she used to be. (今昔对比)c) 表示状态时一般只用 used toTom used to be fat /There used to stand a tree there. (状态)d) was (were) used to +ving 表示“合适于，适应于”He used to work at night . (“习惯”表经常)He was used to working at night.
3、 (习惯表适应)）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 )）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?B. 过去进行时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)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
4、 us.(表示打算)与 always ,often ,usually 等连用表喜爱，讨厌等感情色彩。He was always Changing his mind. 2、过去进行时与一般过去时的区别A. 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”)B、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
5、)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)C、while 时间状语从句中用短暂动词时只能用进行时。例：He broke a chair while he was jumping up and down.D、 While 所在主从句动作大致持续相等时主从句一般都用进行时，但若是持续动词可都用一般过去时，两个动作一长一短时短的用一般时，长的用进行时。I was cooking the dinner while he was playing the piano.(平行)I cooke
6、d the dinner while he played the piano.I saw him while I was walking to the station.3、英语中有四类动词一般不用进行时（不用现在进行时和过去进行时）1)表心理状态、情感的动词，如 love ,hate ,like ,care ,respect ,please ,prefer ,know 等，若用进行时则词意改变。Im forgetting it . (=beginning to forget )2)表存在、状态的动词，如 appear ,exist ,lie ,remain ,stand ,seem 等3)表感
7、觉的动词，如 see ,hear ,feel ,smell ,sound ,taste 等.4)表一时性的动词，如 accept ,allow ,admit ,decide ,end ,refuse ,permit ,promise 等。5、例题考题 1 As she _the newspaper ,Granny _ asleep .(95)A. read /was falling B .was reading /fellC. Was reading /was falling D. read/fell分析 时间从句的动作长，而“入睡”动作短，故前者用过去进行时，而较短动词用一般过去时，选 B考题 2 Tom _ into the house when no one _ .A. slipped/was looking B. Had slipped /lookedC. slipped/had looked D. was slipping /looked分析 此题先要理解好 when ，表“此时”，说明主句中 slipped 是较短行为，而 look 是较长行为的片断，即汤姆溜进房子，此时没人瞧见，故选 A 为正确。
