过去完成时用法小结

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 fini shed 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 patie nts.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,si nee等词连用。如:

He had served in the army for ten yearsbefore 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 sinee he was a ehild. 他告诉我他从小就认识她。He had learned English for eight yearsbefore 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...(冈H…就…),no sooner...than...(刚… 就…),

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 spoke n 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 breakfastafter 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 ploughi ng as soon as they got to the fields.他们一至U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 we got there the basketball match had already started.我们至U那里时,篮球赛已经开始了。

The old man said that he wan ted to go where he hadnever bee n.老人说他想至U他从未去过的地方去。

5.如果句中出现了表示具体的过去时间的状语,句子的内容为过去的实际情况或句子的内容为历史事实时,句中的动词时态常用一般过去时。如:

The teacher said that it was Columbus who first discovered the America n con ti nent. 老师说是哥伦布最早发现了美洲大陆。

6.表述说话人始料未及的事情时,句子的谓语动词常用一般过去时。由于受汉语表述习惯的影响,常会用错时态。

Jack, you are also here! I didn t see you.杰克,你也在这啊!我没有看见你。

一般过去时与现在完成时的用法区别

一般过去时与现在完成时区别专题 一、前言: 初一下学期同学们学习了一般过去时态的相关知识,即将到来的初二上学期英语学习中,现在完成时是重要的学习内容。本文通过对比一般过去时和现在完成时,对现在完成时进行初步讲解,希望使同学们读新学期的学习有所准备。 二、现在完成时 1. 现在完成时的构成 现在完成时是由助动词have (has)+动词的过去分词构成。助动词说明该谓语是属于现在时范围。它和主语的人称、数要保持一致。过去分词是主要的谓语动词,说明句子的意义。 2. 现在完成时的用法 现在完成时表示过去某时发生的行为对主语目前产生的影响。即用过去发生的某个行为来说明现在的某种情况。 We are good friends.(现在的情况) I knew him in 1997.(过去的动作) We have known each other since 1997. (现在完成时把过去的动作和现在联系起来并着眼于现在) (1)表示动作发生在过去某个不确定的时间,但对现在留下了某种影响和结果。常被just、already、yet 等副词修饰。如: -Have you had lunch yet? -Yes, I have. I've just had it. 你(已经)吃午饭了吗?我刚刚吃过。(现在我不饿了) (2)表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止,可能仍然在进行。常带有for和since等表示一段时间的状语。 如:He has taught here since 1981 他自1981年就在这儿教书。(可能还要继续教) I haven't seen her for four years. 我有四年没见到她了。 (3)表示说话前发生过一次或多次的动作,现在成为一种经验,一般译为汉语“过”,常带有twice,ever, never,three times等时间状语。 如:I have been to Beijing twice.我去过北京二次。 3.现在完成时的时间状语 (1)现在完成时属于现在时范围,故不能和过去的时间状语连用。如:yesterday,last Sunday,in1990,three years ago等。但是,在强调动作产生的后果和影响时,可以和一些表示不确定的时间状语连用。 a. 用副词already和yet。already一般用于肯定句中,yet一般用于否定句和疑问句中。 如:We have already finished our homework.我们已完成作业了。 They haven't finished their homework yet.他们还没有完成作业。 b.用ever 和never。多用于否定或疑问句中,表示“曾经”或“从未“等。 如:-Have you ever been to the Great Wall? 你曾经去过长城吗? -I have never been to the Great Wall.我从未去过长城。 c.用表示到说话为止的过去时间状语,如just, before, up to now, the past few years等。 例如:I have seen her before, but I can not remember where. 我以前见过她,但记不起在哪里见过。

英语现在完成时态讲解学习资料

现在完成时 一、定义:表示一个动作在过去发生并对现在产生影响 表示一个动作由过去发生持续到现在有可能停下,也有可能延续下去 表示一个动作从过去开始发生到目前为止已经发生多次。 二、构成:现在完成时是由“助动词have / has + 动词的过去分词”构成的, 其规则动词的过去分词构成与过去式相同,不规则动词的过去分词则需加强记忆。 如:I have just cleaned my clothes.我刚洗过衣服。 My brother has done his homework already. 我的弟弟已经做完他的作业了。 友情提示:在现在完成时的各种结构中,have, has均为助动词,无实际意义,只起构成时态的作用,不可省略。当主语是第三人称单数时助动词用has,其余人称一律用have。 过去分词 1 、规则动词:规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同。 四点变化规则: (1)、一般动词,在词尾直接加“ ed ”。 work---worked---worked ,visit---visited---visited (2)、以“ e ”结尾的动词,只在词尾加“ d ”。 live---lived---lived , (3)、以“辅音字母+ y ”结尾的动词,将"y" 变为"i" ,再加“ ed ”。 study---studied---studied ,cry---cried---cried , play---played---played ,stay---stayed---stayed (4)、重读闭音节结尾,末尾只有一个辅音字母,先双写该辅音字母,再加“ ed ”。 stop---stopped---stopped , drop---dropped--dropped 2 、不规则动词: AAA型 原型过去式过去分词 burst burst burst cast cast cast cost cost cost cut cut cut hit hit hit hurt hurt hurt put put put set set set shut shut shut

现在完成时趣味讲解

现在完成时趣味讲解 现在完成时的含义 可与现在完成时态相连用的常见时间状语 瞬间动词在现在完成时态中的用法 现在完成时的含义 在当今常见的语法书中对现在完成时的定义大多是:现在完成时是指过去发生的至今已经完成或还在继续的动作。在笔者2011年于《海外英语》中发表的《have + -en的构式研究》中曾指出这一说法的稍欠妥之处。因为过去发生的“已经完成”或“未完成”容易让学生产生疑惑:究竟是不是完成时? 笔者认为易仲良教授提出的“式态”的说法以及马承老师提出的“现在完成时表示过去已经发生而与现在情况有关系的动作”这一说法更能让学生理解。事实上,我在初中的教学过程当中也是这样跟学生讲解的,学生们能够较好的理解这一说法,并能自然地将现在完成时与一般过去时区分开来。 常与现在完成时相连的时间状语 在初中阶段,多数考查现在完成时的句子当中都有较为明显的时间状语标志词, 比如以下的这些句子(均摘录自人教版教材):

Have you read Treasure Island yet? I’ve already read it. Have you ever been to a museum? I’ve never been to a science museum. I’ve had this bike for three years. 如果在实际的教学过程当中孤立地让学生记忆这些时间状语标志,无疑会给学生增大学习难度。为了能够提高学生的学习兴趣,我认为可以通过口诀韵律的方式让学生较快地掌握:以前(before)从来不(never)出现,最近(recently)曾经(ever)一两遍(once/twice/many times…), 自从(since+时间点)刚刚(just)for一段(for+一段),至今(so far/up to now)已经(already/yet)很明显。 在实际的教学过程当中,教师可有意识地讲述两个“已经”(already/yet)及(since/for)的区别着重分章节讲解,让学生在有了整体概念的基础上对各个考点进行突破。 瞬间动词在现在完成时中的用法 在人教版的课本附录的语法讲解中,我们可以看到:“某些动词的现在完成时可表示过去某一时间开始并一直持续到现在(包括”现在“在内)的动作或状态,可以和表示延续的时间状语连用。表示持续动作或状态的动词多是延续性动词”。如:

现在完成时的用法

现在完成时的用法 一、概念 现在完成时主要强调过去发生的动作对现在造成的影响,或过去发生的动作还未结束,一直持续到现在或将来,重点在于对现在的影响。 二、理解: 现在完成时用来表示之前已发生或完成的动作或状态,其结果的确和现在有联系。动作或状态发生在过去但它的影响现在还存在;也可表示持续到现在的动作或状态。 四、基本用法: 1.已完成用法(影响性用法)。该用法的现在完成时表示一个过去发生的动作 在过去已经完成,并且这个过去发生并完成的动作对现在有影响或结果,同时 说话强调的或感兴趣的就是这个影响或结果。如:

He has left the city. 他已离开这个城市。(结果。如:他不在这个城市) Someone has broken the window. 有人把窗户打破了。(结果。如:窗户仍破着) Have you seen my bag? 你看到我的手提包了吗?(结果。如:你知道它在哪里吗?) I have bought two apples.我买了两个苹果。(“买”这一动作发生在过去,对现在造成的结果是:拥有两个苹果。) 【注】现在完成时“完成用法”的特点是动作不延续,因此,该时态只能与表示不定的过去时间状语(如:already,just, yet,before,recently等)、频度时间状语(如:never,ever,once等)、包括现在时刻在内的时间状语(如:this morning/month /year..., today等)连用。already,just多用于肯定句中,ever,yet,never多用于疑问句和否定句中。 如:I have already finished my homework.我已经做完家庭作业了。 He has just had his meal.他刚吃过饭。 Have you ever sung this English song?你曾唱过这首英文歌吗? They haven't started yet.他们还没有动身。 We have never heard of it.我们从来没有听说过这件事。 2.未完成用法(持续性用法)。如:该用法的现在完成时表示一个过去发生的动作并未在过去完成,而是一直持续到现在,并且有可能继续下去(也可能到此结束)。此种用法的句中常需一个表示一段时间的状语(由since或for引导),或表示与现在时刻相连的时间状语(如:up to now,so far到目前为止)等。如: He has lived here since 1971. 自从1971年以来,他一直住在这儿。 (动作起始于1971年,一直住到现在,可能还要继续住下去。) We have been in the army for more than 5 years. 我们在部队已经呆了五年多了。 (动作开始于5年前,一直延续至今,有可能还要继续下去。) Have you waited long? 你等了很久吗? We have been busy this afternoon. 今天下午我们一直很忙。 The temperature has stayed hot this week. 这星期天气一直很热。

现在完成时的用法解析

Lead in 一般过去时导入:一般过去时的概念 一般过去时表示过去某个时间发生的动作或存在的状态。 I lost my pen.(过去时) I have lost my pen.(现在完成时) 过去时一般表示过去所发生的动作或存在的状态。“我把笔丢了”,说话人只是想告诉对方在过去的某一个时间里他的笔丢了,仅此而已。(仅仅是在陈诉过去的一个事实,与现在没有关系) New lesson 一.现在完成时的构成: 助动词have/has(not) +动词过去分词 She has turned on the lights. 肯定式:have/ has+过去分词 否定式:haven’t/hasn’t+过去分词 疑问式:把have/has 提到主语前面 肯定回答:Yes,…have/has 否定回答:No,…..haven’t/hasn’t 二.用法 1.表示过去发生的动作对现在造成的影响或结果. 例如:She has gone. 她走了. She went in the past.(She is not here

now.) I have just cleaned my hands. 我刚洗过手。(“洗手”是发生在过去的动作,对现在造成的结果是“手干净了”) I have closed the door. (The door is close now.) She has turned on the lights. (The lights are on now.) He has written his name on the blackboard. (The name is on the blackboard now.) Mother has cooked the dinner. (We can have dinner now.) You have seen the film. (You know what the film is about.) We have cleaned the classroom. (The classroom is clean now.) 2. 表示动作发生在过去,并且一直延续到现在,甚至还可能继续延续下去。这时常和since所引导的短语或从句或for引导的短语连用(for有时可以省去)。以及so far, by now, these days, in the last/past … years/days…等连用。 I have lived here for over ten years. (表示他现在还在这里居住,并且还有可能继续住下去)比较:I lived here ten years ago.(仅仅说明了他十年前在这里记住过的事实,不代表现在他还住在这里) He has studied here since 2006. 都用How long 提问,例: We have learned English for three years. We have learned English since three years ago.

过去完成时讲解及练习题(精讲)

过去完成时 1.概念:过去发生或已经完成的动作对现在造成的影响或结果,或从过去已经开始,持续到现在的动作或状态。 2.时间状语:recently, lately, since…for…,in the past few years, etc. 3.基本结构:have/has + done 4.否定形式:have/has + not +done. 5.一般疑问句:have或has提前 概念:过去完成时表示在过去某一时间或动作之前已经发生或完成了的动作,即"过去的过去(past-in-the-past )"。 ----|-------------------------- |-------------------------------|----------------------------> 那时以前那时现在 构成:过去完成时由"助动词had + 过去分词"构成,其中had 通用于各种人称。 They had already had breakfast before they arrived at the hotel. She had finished writing the composition by 10 :00 this morning. 二、过去完成时的判断依据 1. 由时间状语来判定 一般说来,各种时态都有特定的时间状语。与过去完成时连用的时间状语有: (1 )by + 过去的时间点。 如:I had finished reading the novel by nine o'clock last night. (2 )by the end of + 过去的时间点。 如:We had learned over two thousand English words by the end of last term. (3 )before + 过去的时间点。 如:They had planted six hundred trees before last Wednesday. 2. 由"过去的过去"来判定。 过去完成时表示"过去的过去",是指过去某一动作之前已经发生或完成的动作,即动作有先后关系,动作在前的用过去完成时,在后的用一般过去时。这种用法常出现在:(1 )宾语从句中 当宾语从句的主句为一般过去时,且从句的动作先于主句的动作时,从句要用过去完成时。在told, said, knew, heard, thought等动词后的宾语从句。如: She said that she had seen the film before. (2 )状语从句中 在时间、条件、原因、方式等状语从句中,主、从句的动作发生有先后关系,动作在前的,要用过去完成时,动作在后的要用一般过去时。如: When I got to the station, the train had already left. After he had finished his homework, he went to bed. 注意:before, after 引导的时间状语从句中,由于before 和after 本身已表达了动作的先后关系,若主、从句表示的动作紧密相连,则主、从句都用一般过去时。如:Where did you study before you came here? After he closed the door, he left the classroom. (3 )表示意向的动词,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时表示"原本…,未能…" We had hoped that you would come, but you didn't.

英语中过去完成时和过去完成进行时区别用法

过去完成时和过去完成进行时 过去完成进行时(Past Perfect Progressive Tense) 过去完成式是不能单独用的。我们用的时候,必须有另一个事件。也就是说,假如我们有两件事A 和B,两件事都发生在过去,但A 发生在B 以前,A 应该用过去完成式,B 则用过去式。以下是几个例子: (1)他到台湾以前,曾学过中文。 He had studied Chinese before he came to Taiwan. (2)他念大学以前,曾前工作过。 He had worked before he decided to go to college. (3)我写这篇有关爱尔兰的小说以前,曾去过爱尔兰。 I had been to Ireland before I wrote this book about Ireland's people. (4)我在上大学以前,已经学过微积分。 I had studied calculus before I got into college. (5)周一以前,已经下过雪了。 It had already snowed before Monday. (6)警察到来之前,小偷已经跑了。 When the police arrived, the thieves had already run away. (7)到那时,他的家人已经有半年没有他的消息了。 Until then, his family hadn’t heard from him for 6 months. 如果我们要强调较早发生事件的连续性,我们可以用过去完成进行式。占去完成进行式和现在进行式惟一不同的地方是verb to have 的地方一定要用had 。以下是一些过去完成进行式的例子: 1. I had been watching TV before you called me. 2. I had been working hard in a company for many years before I went to college. 3. He had been studying before he went to class. 4. He had been driving all day before he went to sleep. 过去完成时 1)概念:表示过去的过去 ----|-------|-----|---->其构成是had +过去分词构成。 那时以前那时现在 2)用法 a. 在told, said, knew, heard, thought等动词后的宾语从句。 She said (that) she had never been to Paris. b. 状语从句 在过去不同时间发生的两个动作中,发生在先,用过去完成时;发生在后,用一般过去时。 When the police arrived, the thieves had run away. c. 表示意向的动词,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时表示"原本…,未能…" We had hoped that you would come, but you didn't. 3) 过去完成时的时间状语before, by, until , when, after, once, as soon as。 He said that he had learned some English before. By the time he was twelve, Edison had began to make a living by himself. Tom was disappointed that most of the guests had left when he arrived at the party.
