27、 ，而一般过去时则表示一个 完成的动作 。也就是说用一般过去时，只表示有过这件事；用过去进行时，则强调动作的连续性。 I wrote a letter this morning. 今天上午我写了一封信。 （信写完了）I was writing a letter this morning. 今天上午我在写一封信。 （信不一定写完） The children watched TV yesterday evening. 昨天晚上孩子们看了电视。 （强调过去发生了这件事）The children were watching TV yesterday evening. 昨晚孩子们都在看电视。 （强调昨晚
28、看电视这一动作的持续性）(2) 表示过去的状态、感觉及心理活动的静态动词( 如 be， like， love， hate， fear， own， hear， see， know， want， notice)可用于一般过去时，但通常不用于进行时。如：I hated it when a man spoke with his mouth full of food. 我讨厌人们说话时口里含着食物。(3) 一般过去时与 always， constantly， forever， continually 等连用，表示“过去经常性、习惯性的动作”;而过去进行时与 always， constantly， for
29、ever， continually 等连用，表示动作的重复，常带有感*彩。如：He always got up at six. 他过去总是六点起床。He was always thinking of his work. 他总是一心想到工作。(4) 有时过去进行时可以用来替换一般过去时，但一般过去时表示主语的行为是经过认真考虑的;而过去进行时表示一种较随便或没有进行仔细考虑的行为。如：6I thought that he would agree with us. 我原以为它会同意我们的。I was thinking of persuading him to follow my advice. 我
30、想到了要说服他接受我们的建议6. 使用过去进行时应注意的几点(1) 动词 hope， wonder 等的过去进行时常用来表示提出要求，虽然表示现在的内容，但语气比一般现在时或一般过去时要委婉。如：I was wondering whether you could come to join us. 我想你能否过来跟我们一起活动?7 下面几种情况不用一般过去时而要用过去进行时：(1). 表示过去某一阶段暂时性的习惯动作时。如：Tom was getting up at six oclock every day that week. 汤姆那一周里每天都是六点钟起床。(2). 与 always 连用表
31、示赞美，厌烦等感情色彩时。如：John was always coming to school late. 约翰上学总是迟到。Lei Feng was always doing good deeds for the people. 雷锋总是为人民做好事。(3) 用来描写故事发生的情景时。如：It was a dark night.

32、er.那是一个漆黑的夜晚，风刮得很厉害，雨下得很大，一个解放军战士突然出现在河岸上，他想过河去。(4) when 作并列连词，表示“(这时) 突然”之意时，第一个并列分句用过去进行时，when引导的并列分句用一般过去时。如：I was taking a walk when I met him. 我正在散步，突然遇见了他。We were playing outside when it began to rain. 我们正在外边玩，这时下起雨来了。(5) go, come, leave, start, arrive 等动词可用过去进行时表示过去将来的含义。如：I was leaving for W

34、状语从句中的谓语动词只能是延续性动词。 when 引导的从句谓语动词如果是短暂性动词则用一般过去时，主句是延续性动词则用过去进行时，从句动作发生在主句动作的时间段之内（长动作用过去进行时，短动作用一般过去时） ；如果主句和从句两个谓语动词都是延续性动词则全部用过去进行时,这时 when 和 while 都可以用。 when 从句的谓语动词可以在主句谓语动作之前、之后或同时发生；while 和 as 从句的谓语动作必须是和主句谓语动作同时发生。 when 和 while 两个词还可以用作并列连词，但意思不同， when 相当于“在那时” ，等于 at that time 或 just then;
35、而 while 则相当于“而；却；但是 ”；相当于 but,表示对比关系。 （这一点暂时可以不掌握）eg. I was playing computer games when my father got home.= When my father got home,I was playing computer games.(2) Mother was cooking when/while I was doing my homework.when +短/延while +延7= When/While I was doing my homework, mother was cooking.过去进行时
