仁爱英语 资源共享:过去进行时与一般过去时的区别

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)   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 cooked the dinner while he played the piano.   I saw him while I was walking to the station.
