He was not reading a book at 5:00 yesterday.Was he reading a book at 5:00 yesterday? (Yes, he was./ No, he wasnt.)What was he doing at 5:00 yesterday?二、过去进行时用法：1. 过去进行时主要表示过去某个时刻正在进行的动作，常和表示过去的状语连用。如： （just）then 那时，当时 at this/that time 在这/那时 yesterday afternoon昨天下午 at nine 在九点 last night 昨晚 （at）this time yesterday在昨天这个时候 但在不少情况下，没有表示时间的状语，这时需要通过上下文来表示。 What were you doing at nine last night? 昨晚九点的时候，你在做什么？ I was watching TV at home yesterday afternoon. 我昨天下午正在家里看电视。 They were playing football at this time yesterday.昨天这个时候他们在踢足球。2.过去进行时也可以表示过去某一段时间内正在进行的动作。常与those days, the whole morning, from 8:00 to 12:00 last night等时间状语连用。（1）From 1983 to 1998 , he was teaching at Yale . 从1983到1998年，他正在耶鲁大学教书。（2）They were building a bridge last winter . 去年冬天他们正在造一座桥。 (3) He was writing a book those days. 那几天他正在写一本书3.过去进行时与频度副词always forever， continually， constantly等连用时表示过去经常反复的动作，常常带有埋怨、讨厌、赞扬或喜爱等情绪。 My sister was always forgetting things.(表示埋怨) He was always helping others. (表示赞扬)4. 过去进行时表示过去将要发生的动作。现在进行时可以表示将来的动作，同样，过去进行时也可以表示从过去某时看来将要发生的动作，常用在间接引语中。 Lucy arrived in Beijing last Friday. But she was leaving for Hong Kong the next morning. 上周五Lucy到达北京，但第二天早晨就要动身去香港了。 She asked him if he was coming back for lunch. 她问他午饭是否准备回来吃。5、过去进行时和一般过去时的区别。（1）过去进行时表示过去某时正在进行的动作，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， forever， 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：I 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. The wind was blowing hard and the rain was falling heavily. A PLA man suddenly appeared on the river bank. He wanted to cross the river.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 Wuhan that day. 那天我正要去武汉。She was coming later. 她随后就来。8过去进行时表示婉转语气(只限于want, hope, wonder 等动词)，用以提出请求。如：I was wondering if you could help me.I was hoping you could send me home.三、when, while 的用法 when和while与过去进行时有着密切的关系，他们作从属连词时都有“当.时候”之意，用法稍有不同： when引导的时间状语从句的谓语动词可以是短暂性动词，也可以是延续性动词，而while引导的时间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 +短/延while +延 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;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/While I was doing my homework, mother was cooking.过去进行时巩固练习：（聪明的你一定能全部做对）1 Simon _ (make) a model plane at 8:00 a.m.2 Peter _(do) his homework at seven last night.3 They _ (watch) a football match from 7:00 to 9:00 last night.4 He _(try) to draw a plane on the blackboard at that time.5 What book _ you _(read) when I _ (see)you at four yesterday afternoon?6 While she _ (watch) TV, her son _ (play) outside the room.7 It _ (begin) to rain while we _(work) in the field.8 I _ (do) my homework last night when the light _ (go) out. go out 意为熄灭9 I saw you in the reading room yesterday , Tom.
