一、过去完成时定义:

②过去某动作一直持续到现在将来可能还要延续下去。句中的动作发生在过去之前(过去的过去),即过去完成时动作发生在过去的过去。 He said he had been to Beijing twice. 他说他已经去过北京两次。(因为“说”said就是过去式,而去北京的动作发生在说said 的过去,所以用过完而不用现完。

可概括为:强调过去某一个动作发生在另一个动作前常常用过去完成时态。

二、过去完成时结构:

⑤被动语态:主语+had(hadn't)+been+过去分词

三、过去完成时的基本用法:

(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(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。

例如:By nine o’clock last night, we had got 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,我在车站已经等了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

例如: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。

例如: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。

例如: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 (second, etc)

time (that)…等固定句型中。

例如:Hardly had he begun to speak when the audience interrupted him.

他刚开始演讲,听众就打断了他。

No sooner had he arrived than he went away again.

他刚到就又走了。

It was the third time that he had been out of work that year.

这是他那一年第三次失业了。

四、过去完成时-语法判定:

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: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:

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.

五、过去完成时与现在完成时的区别:

现在完成时表示的动作发生在过去,以现在的时间为基点,但侧重对现在产生的结果或造成的影响,与现在有关,其结构为“助动词 have (has) + 过去分词”;过去完成时则是一个相对的时态,以过去时间为基点,它所表示的动作不仅发生在过去,更强调“过去的过去”,只有和过去某时或某动作相比较时,才用到它。

比较:I have learned 1000 English words so far.到目前为止我已经学会了 1000 个英语单词。

I had learned 1000 English words till then.到那时为止我已经学会了 1000 个英语单词。

— I'm sorry to keep you waiting. 对不起,让你久等了。

— Oh, not at all. I have been here only a few minutes.没什么,我只等了几分钟。(“等”的动作从过去某一时间点持续到现在)

六、过去完成时与一般过去时的区别:

虽然这两种时态都表示过去发生的动作或存在的状态,但在使用时应注意以下几点:

1. 时间状语不同:过去完成时在时间上强调“过去的过去”;而一般过去时只强调过去某一特定的时间。

比较:They had arrived at the station by ten yesterday.

They arrived at the station at ten yesterday.

2. 在没有明确的过去时间状语作标志时,谓语动词动作发生的时间先后须依据上下文来判断:先发生的用过去完成时,后发生的则用一般过去时。

She was very happy. Her whole family were pleased with her, too. She had just won the first in the composition competition.

3. 当两个或两个以上接连发生的动作用 and 或 but 连接时,按时间顺序,只需用一般过去时来代替过去完成时;另外,在 before , after ,as soon as 引导的从句中,由于这些连词本身已经表示出时间的先后,因此也可以用过去时来代替过去完成时。

He entered the room, turned on the light and read an evening paper.

七、三种时态用法总结

1.We started to learn English 5 years ago.

一般过去时表示在过去某时发生的动作或存在的状态。

5 years ago now

2. We have learned English for 5 years.

现在完成时表示的动作发生在过去,但侧重对现在产生的结果或造成的影响,与现在有关。其结构为:“助动词 have(has)+过去分词”

Five years ago have learned now

3.过去完成时表示在过去某个时间或动作之前已经发生或完成了的动作或存在的状态,即“过去的过去( past-in-the-past )”。

past in the past past Now

We had learned English 4 years by last year.(had learned区域)

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。

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?

过去分词的用法 一、构成:规则动词的过去分词是有动词原形+ed构成的,不规则动词则有各自构成。 二、基本特点:过去分词在句子中的基本用法有两点:1.与逻辑主语之间是被动关系 2.表示完成的动作 三、过去分词的用法: 1.作表语:过去分词作表语时,一般同时具备被动与完成的含义 例如:(1)The cup is broken.(2)He is retired. (3)After running,he is tired. 【注意】过去分词作表语时,已经变成形容词性质,主要表示主语的状态(被动完成),而被动语态则表示动作. 例如:(1) The cup was broken by my little sister yesterday. 茶杯是昨天我小妹打碎的.(是被动语态,表示动作) (2)The cup is now broken. 茶杯碎了.(过去分词作表语,表示状态) 【注意】有些动词如interest, bore, worry, surprise, frighten 等通常用其过去分词形式来修饰人,表示“感到……” 用-ing 形式来修饰物,表示“令人……” 例如:The book is interesting and I'm interested in it. 这本书很有趣,我对它很感兴趣. 2.做定语 作定语用的过去分词其逻辑主语就是它所修饰的名词.及物动词的过去分词作定语,既表被动又表完成;不及物动词的过去分词作定语,只表完成. 1)单一过去分词作定语,常置于其所修饰的名词之前,称作前置定语。 例如:We must adapt our thinking to the changed conditions. 我们必须使我们的思想适应改变了的情况. 2)过去分词短语用作定语时,一般置于其所修饰的名词之后,相当于一个定语从句,称作后置定语。 例如:The concert given by their friends was a success.他们朋友举行的音乐会大为成功. 3)过去分词短语有时也可用作非限制性定语,前后常有逗号. 例如:The meeting, attended by over five thousand people, welcomed the great hero. 4)用来修饰人的过去分词有时可以修饰与人有关的表情,面貌,举止行为以及感觉等,这时不能用v-ing形式例如:The boy looked up with a pleased expression. His satisfied look showed that he had passed this exam. 3.作状语 作状语的过去分词在句子中多表示被动和完成两重含义。 1)时间状语:A.当和谓语动词动作同时发生时,一般仅表示被动,可以用when从句代替。 例如:Faced with difficulties,we shouldn’t withdraw for any excuse. B.当表示动作发生在谓语动词之前时,通常既表被动又表完成,可用after从句代替,也可用现在分词的被动完成形式代替。 例如:Caught by the police,the thief lay on the ground,crying and shouting. 2)原因状语:过去分词所表示的动作多有被动和完成两重含义。 例如:Written in a hurry, this article was not so good! 因为写得匆忙,这篇文章不是很好. Welcomed by all the students,we expressed own true thanks to them.被全体同学欢迎,我们表达真挚的感激【注意】有些过去分词因来源于系表结构,作状语时不表被动而表主动.这样的过去分词及短语常见的有: lost (迷路); seated (坐); hidden (躲); stationed (驻扎); lost / absorbed in (沉溺于); born (出身于); dressed in (穿着); tired of (厌烦). 等,这种结构可以改写成一个because引导的主系表结构句子。 例如:Lost / Absorbed in deep thought, he didn't hear the sound.因为沉溺于思考之中,所以他没听到那个声音. Tired of the noise,he decided to move to the country.因厌倦了噪音,他决定搬到农村去。 Dressed in an orange dress,she looked more beautiful than before.穿上橘红色连衣裙,她看起来比以前更美3)条件状语:作条件状语时,一般只表被动含义。相当于if引导的条件状语从句。 例如:Grown in rich soil, these seeds can grow fast. 如果种在肥沃的土壤里,这些种子能长得很快. 4)伴随情况:表示伴随谓语动词发生的另外动作,位于主语之后,用逗号隔开,可以同时表示被动与完成, 例如:The mother ran across the street,followed by her little son. 5)结果状语:表示发生在谓语动词后的动作,位于主句后用都逗号分开,也可以同时表示被动与完成。 例如:He listened to the hero’s story,moved to tears. 【注意】状语从句改成过去分词作状语时有时还可保留连词,构成"连词+过去分词"结构作状语. 例如:When given a medical examination, you should keep calm. 当你做体格检查时要保持镇定.

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.
