过去完成时语法精讲 一、过去完成时的概念与结构特点 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. 3. 根据上、下文来判定。 【 I met Wang Tao in the street yesterday. We hadn't seen each other since he went to Beijing.
Grammar语法:simple present tense 现在完成时 A表示过去发生或已经完成的某一动作对现在造成的影响或结果 I am doing my homework. I have done my homework. B表示动作或状态从过去某一时刻开始，一直延续到现在，而且可能还要继续下去。 I’ve known Alice for three years. 现在完成时的构成： 主语+have/has +动词的过去分词. I have done my homework. 1.否定：have, has后面加not . I have not done my homework. 2.一般疑问句：have, has提到主语前Have you done your homework? 区别： has gone to:表示某人已去了某地，而没有回来(去了没回) has been to :表示去过某地(去过已回来) has been in/at(in表示相对大一些的地点;at表示相对小一些的地点): 表示一直呆在某地,常与时间段搭配. since+时间点=for+时间段since+一般过去时态的时间状语从句=since+时间点+ago
现在完成时往往同表示不确定的过去时间状语连用 already(肯定句中)，yet(否定，疑问，句末)，just(刚刚), before(之前), recently(最近), still, lately, never等: I have already finished my work. I haven’t finished my work yet.(否定句) Have you finished your work yet?(一般疑问句) 动词过去式和过去分词的变化相同 一般在动词词尾直接ed. 如：pick → picked → picked; wish → wished → wished; stay → stayed → stayed A-A-A: let → let → let; put → put → put; read → read → read, cut→cut→cut A-B-B: lend → lent → lent; build → built → built; send → sent → sent buy → bought → bought; bring → brought → brought; A-B-C: choose→chose→chosen do→did→done see→saw→seen drink→drank→drunk go→went→gone take→took→taken A-B-A: run→ran→run come→came→come
英语现在完成时语法详细讲解与配套习题 一、现在完成时用来表示之前已发生或完成的动作或状态，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。其构成： have (has) +过去分词。规则变化的过去分词与过去式的变化一样，在动词词尾加ed; 不规则变化的过去分词见不规则动词表，需要同学记忆。 现以see the film为例将现在完成时的肯定句，否定句和疑问句列表如下： 肯定句：I/You/We/They have seen the film. He/She /It has seen the film. 否定句：I/You/We/They have not/ haven’t seen the film. He/ She/It has not/hasn’t seen the film. 疑问句：Have I/you/they seen the film Yes, you/ we/I/they have. No, you/ we/I/they haven’t. Has he/she/it seen the film Yes, he/ she/ it has. No, he/ s he/ it hasn’t. 二、用法：现在完成时既涉及过去，又联系现在。 标志词词义用法位置 already已经肯定句句中或句末 ever曾经疑问句、肯定句句中 never从未，从来不陈述句，不和not 连用句中 (ever)since自从肯定、疑问、否定句中 for后接一段时间肯定、疑问、否定句中 just刚刚，正好肯定句句中 yet还疑问句、否定句末 recently最近肯定、否定、疑问句句末 once, twice, a few times几次肯定、疑问句末 during/over /in 在过去的一段时间里肯定、疑问、否定句末 the past/last + 一段时 间 It’s the first time I …这是我第一次…肯定句前
第一章动词之时态 第三节过去完成时 教学时间：2课时 教学目标：通过本次课的学习，使学生理解过去完成时的形式意义，明白一般过去时和过去完成时的区别，并能写出结构语法正确的现在完成时。 教学重点：过去完成时的意义和与一般过去式的区别。 教学步骤： 一.导入 回顾现在完成时 现在完成时的意义：过去发生的动作对现在的影响或从过去开始发生一直持续到现在，着眼点为现在。 二.讲解 1). 过去完成时的形式和意义 回顾： 一般现在时： 主语 + do/does 或 be 一般过去时： 主语 + did或 was/were
现在完成时： 主语 + have/has + done 过去完成时： 主语 + had + done 课堂练习1：划线识别题（划出下列过去完成时的用法） 1.I had been at the bus stop for 20 minutes when a bus finally came. 2.She had left before her parents arrived. 3.We had learned English for 5years by the end of last month. 过去完成时的意义： 引例句： ?他们去年结婚了。 ?They got married last year. ?截止到去年他们已经恋爱五年了。 ?They had been in love for five years by last year. 过去完成时的意义: 当表示过去某一动作发生之前就已经完成的一动作即“过去的过去”时，用过去完成时。 用法： 1.截止到上个月，我就已经学了5000单词了。 I had learned 5000 thousand words by the end of last month. 介词by + 一般过去时的短语或句子，表示在…之前。 By the end of last week, he had wrriten ten books. By the time he was ten, he had made a lot of money. 2.她说她已经吃过早饭了。 She said she had had breakfast. 过去完成时常常用在told, said, knew, thought等动词的宾语从句中，这时从句中的动作发生在主句表示的过去的动作之前。 练习： She said she ______ (see) the film before.
现在完成时讲解及练习(附答案)-名师精讲
现在完成时 先看几个例句： 1. I have cleaned my room. 我已打扫了房间。 2. He hasn’t finished his homework. 他还没完成作业。 3. Have you read this novel ? 你看过这本小说吗？ : make--- hurry---watch--- swim--- be--- talk--- want--- study--- stop--- take--- see--- like---
二、用法：1.表示过去发生的某一动作对现在造成的影响或结果。 I have cleaned my room. 我已打扫了房间(房间现在是干净的，不需要打扫了) They have left. --他们已经离开了,也就是说现在他们人不在这里 I have had my lunch.--我已经吃过午饭了,也就是说我现在不饿 2.表示过去已经开始, 持续到现在的动作或状态, I have learnt English for more than ten years.我已经学了10多年的英语。 She has swum since half an hour ago.我已经游泳了半个小时 3表示人曾有过或到目前为止从未有过的经历. I have never had a car (我从未有过汽车。) I have been there twice. 动词填空： 1._____ you ________(clean) the room? Yes, we __________(do) that already. When _______ you ______(do) it?
时态讲解：现在完成时 （1）构成：现在完成时由助动词have + 过去分词构成，助动词have 有人称和数的变化。第三人称单数用has，其余用have. 现在完成时的否定式直接在助动词后面加上not、疑问式是把助动词提到主语之前。以study 为例，其否定式、疑问式和简单回答形式如下： （2）用法： 1）现在完成时通常表示在说话之前已经完成的动作或存在的状态。说话人强调的是该动作或状态对现在的结果或影响。 My daughter has just gone out. 我女儿刚出去。 I’m sure we’ve met before. 我肯定我们以前见过面。 She has arrived. 她到了。 2）表示持续到现在的动作或状态，往往和包括现在在内的表示一段时间的状语连用，如recently, already, just, lately, for…, since…,yet等。如： I haven’t heard from her these days. 这些日子我没有收到她的信。We haven’t seen you recently. 最近我们没有见到你。 They have been away for two years. 他们离开已经两年了。She has been with us since Monday. ★注意： 1）since和for的区别 since后接时间点，如1993，last term, yesterday, the time I got there。for后接一段时间，表示“长达多久”，如ten years, a while, two days等。 Exercise: 用since和for填空 1. Jim has been in Ireland ______ Monday. 2. Jill has been in Ireland ______ three days. 3. His aunt has lived in Australia ______15 days. 4. Mary is in her office. She has been there ______ 7 o'clock. 5. India has been an independent country ______1974. 6. The bus is late. They've been waiting ______ 20 minutes. 7. Nobody lives in those houses. They have been empty ______ many years. 8. Mike has been ill ______a long time. He has been in hospital ______ October. 2）表示短暂意义的动词如arrive, leave, borrow, buy, begin, start, die等，在完成时当中不能和表示一段时间的状语连用，因为它们表示的动作不可能持续。因此，不能说： He has come here for 2 weeks. × The old man has died for 4 months. × They have left only for 5 minutes. × 以上三句话可以改为： He has been here for 2 weeks. The old man has ______ _______ for 4 months. They have

现在完成时间和现在完成进行时 一、现在完成时 1. 通常使用现在完成时的几种情况 （1）表示过去发生的事对现在的影响 Justin has disappeared, so Kelly is very sad.

He hasn’t finished his homework yet. I’ve met the old man somewhere before. （2）表示从过去开始，并一直持续到现在，一般用for/since短语或由since 引导的时间状语从句。在介词for后一般跟表示一段时间的短语，在since后一般跟表示某个时间的短语，或表示过去时间的状语从句。 We haven’t seen him for two days/since last Monday. We haven’t seen him since he left Nanjing. 4. 现在完成时的应用 (1) 非持续性动词go, come, leave, borrow, buy, die, join的完成时的肯定式不能与时间段连 用，若要接用时间段状语，则应换成相应的持续动词或状态动词。如： He has left. 他走了。 He has been away for an hour. 他走了一个小时了。 Can I borrow that book? 我可以借那本书吗? How long can I keep the book? 这本书我可借多久？ 注意：非持续性动词的否定完成时可与时间段状语连用。如： He has not borrowed the book since then. 从此以后，他再也没有借这本书了。 (2) have / has been to 表示曾经去过某地，但现在不在那儿；have / has gone to表示现在已去 某地，现在不在这儿。如： He has been to Canada, but now he is working in our company. 他去过加拿大，现在在我们公司工作。
现在完成时态 （一）定义：两种情况 1>表示过去发生或已经完成的某一动作对现在造成的结果或影响 2>从过去开始一直延续到现在的动作或保存的状态，强调的是现在的情况，将来还有可能继续下去。 （二）基本结构：主语+have/has+过去分词(done) PS:根据主语的单复数来确定助动词是选用have还是has. ①肯定句：1>主语+have/has+done……. 2>主语+have/has+been+doing……这是现在完成进行 时同样插在现在完成时态这里，也是提到主要的 用法，特别地它带有一些感情色彩如激动、抱 怨…… Eg: I have trained 80 students I joined the education institution(教育机构) 译：在过去的两个小时里，他一直在调试设备。（暗含着现在还在调试，还有可能继续下去）调试的动词原形：debug ②否定结构：主语+haven’t / hasn’t + done +…… ③一般疑问句中：Have/Has+主语+ done+……? 肯定回答：Yes,主语+have/has. 否定回答：No,主语+have/has not . Eg: Have you ever been to an amusement park?
肯定回答：Yes, I have . 否定回答：No, I haven’t. 注意：have /has been to + 地点：去过某地（已回），表示“到(去)过某处”，现在已不在那个地方。在谈起自己曾经去过某个地方时，可以用到。区别于：have/has gone to + 地点：去了某地（未回），表示“去/到了某处” Eg: Has she gone to Hongkong ? 译：她已经去香港了吗？(已到达香港还未回来或者在去香港的路上) 上述的have/has been to和have/has gone to可以用来表达自己平常出差的一种状态。 特殊疑问句：特殊疑问词（What/Why/Who/…）+have/has+主语+done……？ （三）具体用法 1）过去发生的动作对现在产生的影响或结果，或说话时已完成的动作。常见的状语有：now，already, yet, ever(曾经), ever since（自那时起），never, till / until, this week /month/year，many times 等包括现在时间在内的状语。 Eg：I have been over my English study plan now.（be over 代替了finish）Eg: I think that the problem is that I haven't (yet ) figured out what I want.划线句子做整个句子的宾语从句，句子的结构比较复杂，仔细分析译：我认为问题就是我还没有弄清楚自己要的是什么 Eg: What's the best gift you have ever received? 定语从句修饰gift
过去完成时态 （一）定义：①表示发生在过去的动作对过去晚些时候造成的影响或结果②过去某一动作一直持续到过去晚些时候将来可能还要延续。发生在前的那个动作【过去的过去】 （二）基本结构：主语+had+过去分词vpp.(done) ①肯定句：主语+had+过去分词. ②否定句：主语+had+not+过去分词. ③一般疑问句：Had+主语+过去分词? 肯定回答：Yes,主语+had. 否定回答：No,主语+had not . ④特殊疑问句：特殊疑问词或词组+一般疑问句（Had+主语+过去分词）？ ⑤被动语态：主语+had（hadn't)+been+过去分词 （三）用法： （1）表示在过去某一时刻或动作以前完成了的动作，也可以说过去的时间关于过去的动作。即“过去的过去”。可以用by, before等介词短语或一个时间状语从句来表示，也可以用一个表示过去的动作来表示，还可能通过上下文来表示。 例如：By nine o’clock last night, we had gotten 200 pictures from the spaceship. 到昨晚9点钟，我们已经收到200 张飞船发来的图片。 （2）表示由过去的某一时刻开始，一直延续到过去另一时间的动作或状态，常和for, since构成的时间状语连用。 例如：I had been at the bus stop for 20 minutes when a bus finally came. 当车来的时候，我在车站已等了20分钟。 He said he had worked in that factory since 1949. 他说自从1949年以来他就在那家工厂工作。 （3）叙述过去发生的事情，在已叙述了过去发生的事情后，反过来追述或补述以前发生的动作时，常使用过去完成时。 例如：Mr. Smith died yesterday. He had been a good friend of mine. 史密斯先生昨天去世了。他以前是我的好友。 I didn’t know a thing about the verbs, for I had not studied my lesson. 我对动词一无所知，因为我没有好好学习功课。 （4）在含有定语从句的主从复合句中，如果叙述的是过去的事，先发生的动作常用过去完成时。 例如：I returned the book that I had borrowed. 我已归还了我借的书。 She found the key that she had lost. 她丢失的钥匙找到了。 （5）过去完成时常常用在told,said,knew,heard,thought等动词后的宾语从句（或间接引语）中，这时从句中的动作发生在主句表示的过去的动作之前。 例如：He said that he had known her well. 他说他很熟悉她。 I thought I had sent the letter a week before. 我认为我一星期前就把信寄出去了。 （6）状语从句：在过去不同时间发生的两个动作中，发生在前，用过去完成时；发生在后，用一般过去时。 如when,before,after,as soon as,till/until引导的
过去完成时 （1）表示在过去某一时刻或动作以前完成了的动作，可以用by, before等介词短语或一个时间状语从句(在复合句中，由时间连接词引导的状语从句叫做时间状语从句)来表示，也可以用一个表示过去的动作来表示，还可能通过上下文来表示。 例；By nine o’clock last night, we had got 200 pictures from the spaceship.到昨天晚上9点钟，我们已经收到200 张飞船发来的图片。 （2）表示由过去的某一时刻开始，一直延续到过去另一时间的动作或状态，常和for, since 构成的时间状语连用。 例；I had been at the bus stop for 20 minutes when a bus finally came.我在车站已经等了20分钟,一辆公共汽车终于来了。 He said he had worked in that factory since 1949.他说他自从1949年以来他就在那家工厂工作。 （3）叙述过去发生的事情，在已叙述了过去发生的事情后，反过来追述或补充以前发生的动作时，常使用过去完成时。 例；Mr. Smith died yesterday. He had been a good friend of mine. 史密斯先生昨天就去世了。他以前是我的好朋友。 I didn’t know a thing about the verbs, for I had not studied my lesson. 我对动词一无所知，因为我没有好好学习功课。 （4）在含有定语从句的主从复合句中，如果叙述的是过去的事，先发生的动作常用过去完成时。 例；I returned the book that I had borrowed.我已归还了我借的书。 She found the key that she had lost.她发现她失去了的钥匙。 （5）过去完成时常常用在told,said,knew,heard,thought等动词后的宾语从句（或间接引语）中，这时从句中的动作发生在主句表示的过去的动作之前。 例；He said that he had known her well.他说他早就很了解她了。 I thought I had sent the letter a week before.我认为我一星期前就把信寄出去了。（6）状语从句：在过去不同时间发生的两个动作中，“发生在过去的过去”，用过去完成时；发生在后，用一般过去时。 如when,before,after,as soon as,till/until引导的 e.g：When I woke up, it had already stopped raining.我醒来时雨已停了。 She didn’t go to bed until she had finished her work.她直到把工作做完之后才睡觉。 注意：如果两个动作紧接着发生，则常常不用过去完成时，特别是在包含before和after 的复合句中，因为这时从句的动作和主句的动作发生的先后顺序已经非常明确，这时可以用一般过去时代替过去完成时。 e.g：After he arrived in England, Marx worked hard to improve his English. 马克思到达英格兰之后，努力提高他的英语水平。 （7）动词think, want, hope, mean, plan, intend等用过去完成时来表示过去未曾实现的想法，希望，打算或意图等。 e.g：They had wanted to help but could not get there in time. 他们本来打算去帮忙，但没有及时赶到那里。 We had hoped to be able to come and see you . 我们本来希望能来看看你。 （8）过去完成时还可用在hardly when no sooner than It was the first
