初中英语现在完成时详解

现在完成时 一、现在完成时构成 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: 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.

①for+时段 ②since+过去一个时间点(译为:自从……以来) ③since+时段+ago ④since+从句(过去时) ⑤It is+时段+since+从句(过去时) Mary has been ill?for three days. I have lived here?since 1998. 注意: 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。3、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. × 4、has gone (to),has been (to), has been (in)?的区别 Have/Has gone(to) :去了(现在不在说话现场,可能在路上和已经到) Where is your father?He has gone to Shanghai. Have/Has been (to) :去过(已不在去过的地方) My father has been to Shanghai. Have/has been in:呆了多久(还在所呆的地方) My father has been in Shanghai?for two months. /since two months ago. 5、现在完成时不能和表示过去的时间状语连用,如yesterday, last year, in 1976, two days ago, just now, when I came in,但可以和already, yet, sometimes, always, often, before, lately, recently, once, twice, ever, never等连用。不能与when连用。

初中英语过去完成时语法精讲

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.

英语过去完成时练习全集及解析

英语过去完成时练习全集及解析 一、初中英语过去完成时 1.She said when she got to the cinema, the film ________ for 5 minutes. A. has begun B. had begun C. has been on D. had been on 【答案】 D 【解析】【分析】句意:她说当她到达电影院的时候,电影已经开始五分钟了。根据got 可知,电影开始五分钟属于在过去某时间前已经存在的状态,应该用过去完成时,所以排 除A和C。开始begin,电影已经开始了五分钟是存在的状态,要用延续性的动词,所以要 将瞬间动词begin改为be on,故选D。 【点评】此题考查动词的时态问题以及瞬间动词和延续性动词的区别。 2.Simon ________ the piano for ages when he gave his first concert. A. has played B. is playing C. had played D. will play 【答案】 C 【解析】【分析】句意:西蒙举行第一次音乐会时,他已经弹了很多年钢琴了。根据时间 状语when he gave his first concert.可知此处用过去的时态,表示先弹钢琴弹了很多年,然 后开了音乐会,表示过去的过去,应该用过去完成时:had+动词的过去分词,故答案为C。 【点评】考查过去完成时。掌握过去完成时的意义(过去的过去)和构成:had+动词的过去分词。 3.By the time I finished my homework,my mother . A. slept B. has been asleep C. was asleep D. had been asleep 【答案】 D 可知此处应为过去完成时,故选 D. 和“ finished” 【解析】【分析】由上文“By the time ” 【点评】考查过去完成时。 4.By the end of 2012, many buildings built in our city. A. have been B. have C. had been D. will 【答案】 C 【解析】【分析】句意:到2012年底,我们的城市里已经建成了很多大楼。Buildings是build这一动作的承受者,该用被动语态。而被动语态是由“be + 及物动词的过去分词”构成。根据By the end of 2012可知该用过去完成时,所以选C。

高中语法过去完成时详解讲解学习

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

初中过去完成时讲解

过去完成时用法讲解 一、概念:表示过去的过去,其构成是had +过去分词。 二、用法: 1. 表示某一动作在过去某一时刻之前已完成。例如: He had gone to bed by 10:00 last night. (昨夜十点钟之前他已上床去睡了。) 2. 与一般过去时搭配,表达某一动作在过去的动作发生时已完成。例如: The train had started when I got to the station. (当我到达车站时火车已开走了。) # The minute I saw a lady getting off the bus, I knew it was she, for I had seen her before. (我一看到正在下公共汽车的那位女士就知道是她,因为我以前看见过她。) 解说:使用过去完成时在简单句里表达某一动作在过去的某一时刻已完成时,该过去的时刻常以“by +过去时间”的短语来表达。例如下面的说法是不正确的: He had gone to bed at 10:00 last night. 若是要说“at 10:00 last night”就必须用一般过去时“He went to bed...”。请再观察下面的句子试比较:It had rained yesterday. (误) It rained yesterday.(正) 或许你会说:“昨天下了雨,可是今天已放晴了,下雨已是过去的事,而且已经下完了,所以就用过去完成时……。”这就是最令同学们对一般过去时和过去完成时感到混淆和困惑的。实际上只要我们了解下面的两点原则就可以消除这种现象。 1. 由过去的时间作状语来修饰动词的句子都使用一般过去时。 ; 2. 除非从谈话的先后关系和上下文关系对过去的动作完成的基准点可以确定以外,应该避免在简单句中使用过去完成时。 三、过去完成时常用的连词有:before, by, until, when, after, once, as soon as等。例如: 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. 四、在什么情况下使用过去完成时 1. 在told, said, knew, heard, thought等动词引导的宾语从句中,一般用过去完成时。例如: She said (that) she had never been to Paris. … 2. 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。例如:When the police arrived, the thieves had run away. 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……”。例如: We had hoped that you would come, but you didn't. 典型例题: The students ________ busily when Miss Brown went to get a book she ____ in the office. A. had written, left , B. were writing, has left C. had written, had left D. were writing, had left 答案D。“把书忘在办公室”发生在“去取书”这一过去的动作之前,因此“忘了书”这一动作发生
