过去完成时态用法小结

过去完成时态的用法小结 默认分类2009-12-27 12:54:52 阅读281 评论0 字号:大中小订阅 一、过去完成时适用场合 1. 过去完成时表示在过去某一时间或动作以前已经完成了的动作。这个过去的时间常用by,before等介词短语或一个时间状语从句表示,也可以暗含在上下文中。 I had finished my homework before supper.我在晚饭前就把作业做完了。 The play had already started when we got to the theatre. 我们到剧场时戏已经开始了。 By the end of June they had treated over 10,000 patients. 到六月底他们已经治疗了一万多病人。 2. 过去完成时还可表示过去某一时刻之前发生的动作或状态持续到过去某个时间或还要持续下去,常与for,since等词连用。如: He had served in the army for ten years before he retired last year. 他在部队干了十年,去年退役了。 He told me that he had known her since he was a child. 他告诉我他从小就认识她。 He had learned English for eight years before he went to England for further study. 他在去英国深造前,已学了八年英语。 3. 在一段情景连贯的文字中,先发生的事放在后面叙述时,要用过去完成时。如: Tom flew home, but his father had already died. 汤姆乘飞机回家,他的父亲却已经去世了。4. 过去完成时也用于hardly...when..., no sooner...than..., It was the first time + that分句等一些固定句型中。 He had no sooner left the room than they began to talk about him. 他刚离开房间,他们就议论起他来。 We had hardly begun when we were told to stop. 我们刚开始就被叫停。 It was the first time that he had ever spoken to me in such a tune.他用这样的语调跟我讲话,这是第一次。 二、过去完成时与一般过去时的比较 1. 当一个由before, after, as soon as 等连词引导的从句所表示的动作和主句的动作紧接着发生时,两个动作均可用一般过去时来表示。 We had breakfast after we did morning exercises. 做完早操后,我们吃早饭。 The train started to move just before he reached the platform. 他到月台时火车刚开走。 They started ploughing as soon as they got to the fields. 他们一到地里就开始耕地。 2. 按时间顺序叙述两个或两个以上接连发生的动作时,用一般过去时。 He entered the room, turned on the light and sat down at the table. 他走进屋子,打开灯,坐在桌子旁。 3. 在表示某人过去未曾完成的“心愿”、“打算”、“计划”、“想法”、“许诺”等时,hope, mean, plan, think, intend等谓语动词常用过去完成时。 I had hoped to be back last night, but I didn’t catch the train. 我本来希望昨晚回来的,但没搭上火车。 We had thought to return early but they wouldn’t let us go. 我们本想早回来的,但他们不让我们走。 4. 在表示过去的句子中出现常与完成时态连用的词,如:already,yet,since,for,ever,never及次数名词等时,常用过去完成时来表示。

when做并列连词的用法

when 和引导时间状语从句的从属连词when 是不同的。这主要表现在以下几个方面: 1. 位置:when 引导时间状语从句时,该从句可放在主句之前也可放在主句之后;而并列连词when 只能位于两个分句之间,而且前面常常有逗号。例如:Come when you please. 你高兴来就来吧。(when 为从属连词)When I saw him,he was writing to a friend of his. 我看见他时,他在给一个朋友写信。(when 为从属连词)I was taking a walk,when I came across him. 我正在散步,突然碰见了他。 2. 意义:when 作从属连词用时,它所引导的从句表示主句中谓语动词动作发生的时间,即作“当……时”解;而并列连词when 连接的两个分句中,第一个分句表示的是背景,第二个分句表示的是一种突然的、意想不到的情况或过早发生的事情。when 通常含“这时突然”之义。例如:I was thinking of this,when I heard my name called. 我正想着这件事,突然听到有人叫我的名字。I had just fallen asleep,when the boor-bell rang. 我刚入睡,门铃突然响了起来。这种意义在孤立的句子中可以理解到,在文章中更能体会得到。如在“ I was wandering through the street when I caught sight of a tailor's shop ”一句中,“在街头漫步”只是“看见有家缝纫店”的时间,其后作者怎样走进缝纫店,想要什么样的衣服,怎样受到伙计的奚落,又怎样受到老板的奉承等情景均与“漫步街头”没有直接的因果关系。 3. 时态:when 引导的时间状语从句中可以根据句意的需要用一般现在时.一般过去时、过去进行时、分别说明现在,过去,甚至将来的行为;并列连词when 后面的分句中通常用非延续性动词的一般过去时,其前表时间的分句中可用:( 1 过去进行时表示过去某时间正在进行的动作。 例如: I was cooking when I heard her knocking at the door. 我正在做饭,突然听到她敲门的声音。 He was thinking about the problem,when an apple fell to the ground. 他正在思考这个问题,突然有一只苹果掉到了地上。 (2 )was /were going to,was / were about to,was / were on the point of 表示过去某一时间将要发生的动作。 例如: I was just going when he came in. 我正要走,这时他就进来了。 We were about to start when it began to rain. 我们刚要动身天就开始下起雨来了。 He was on the point of leaving,when someone knocked at the door. 他刚要走就有人敲门。 (3 )过去完成时表示过早发生的事情。请看下述两种场合: (a )过去完成时和含否定意义的hardly,scarcely,nearly 连用,和just,little 连用,或者与否定词not 连用时,表示“刚……,就……”的意思。 例如: I had hardly opened the door when he hit me. 我刚一开门他就打了我一下。 I had nearly reached the town,when the young man suddenly said very slowly,“ Do you speak English ”我快要进城了,年轻人突然慢慢地说:“你会讲英语吗” I had been there little more than a week when I set to work in earnest. 我到那儿还不超过一个星期就开始认真干起活来。 I had not been reading for half an hour when I heard steps outside.

过去完成时知识点总结和题型总结(word) 一、初中英语过去完成时 1.—We all went to the park except you last weekend. Why didn't you come? —Because I the park twice. A. have gone to B. had gone to C. had been to D. have been to 【答案】 C 【解析】【分析】have gone to去了(尚未回).have been to去过(已回),根据句意在last weekend之前去过,所以用过去完成时,故选C。 【点评】本题考查过去完成时的用法,表示在过去某一时间前已经发生的动作。 2.Sue didn't go to see the film with us last week because she ________________ it with her mother. A. has seen B. had seen C. will see D. saw 【答案】 B 【解析】【分析】句意:苏上星期没和我们一起去看电影,因为她和她妈妈一起看过了。 A.已经看了,现在完成时; B.已经看了,过去完成时; C.将看,一般将来时; D.看了,一般过去时。Sue和妈妈看了电影的影响是上周Sue没有和我们看电影,所以用完成时,根据didn't可知是与过去有关,所以用过去完成时,结构是had+动词过去分词,see的过去分词是seen,故选B。 【点评】考查过去完成时,注意平时识记其结构,理解句意。 3.Jake _____his key in the office so he had to wait until his wife _______ home. A. has forgotten … comes B. forgot… come C. had left… came D. had left…would come 【答案】 C 【解析】【分析】句意:杰克把他的钥匙丢在办公室了,因此他不得不等到他的妻子回家。结合语境可知前文描述的是过去某时前已经完成的动作,故用过去完成时态。下文指的是过去某时的动作,故用一般过去时态。选C。 【点评】英语中的时态主要是借助于时间状语与上下文语境来进行判断。解答此类题型,首先要注意句子中的时间状语,如果没有则要通过分析上下文,结合语境来判断句子的时态。 4.When I ______ the cinema, the film _______for ten minutes A. got to; has begun B. arrived at; has been on C. reached; had begun D. hurried to; had been on

并列连词when相关的句式归纳

并列连词when相关的句式归纳 2006年普通高等学校招生全国统一考试(辽宁卷)中有这样一道单项填空题:He was about halfway through his meal ___ a familiar voice came to his ears. A.why B.where C.when D.while 解析:答案是C。此处when作并列连词,表示“就在此刻(and just then)”“,突然(and suddenly)”,该句译为:“饭刚吃到一半儿的时候,熟悉的声音传到了他的耳朵里。” 这里when引导的并不是我们所认为的时间状语从句而是并列句。when的意思是这时而不是当什么时候。在这个句型中when所引导的从句恰恰是句意的重心,when在这里起到一个修辞的作用表示后一动作的发生的出乎意料,而前面一句是为后一句谓语动词的发生提供背景。when 为并列连词。在我们的教材中并不鲜见。如: I'd just about given myself up for lost when I was spotted by a ship. 我正感到绝望时,一艘船发现了我。【Unit 3 Book 3】 33. She had just finished her homework ___ her mother asked her to plactised playing the piano yesterday.【09福建卷】 A. when B. while C. after D. since 7.
