最新过去完成时和虚拟语气讲解和练习
过去完成时注意：过去完成时表示过去某一时间或某一动作之前已经发生或完成的动作，动作发生的时间是"过去的过去".它是一个相对的时态，只有在和过去某个时间或动作相比较时才会用到。
E.g. By the end of the match，they had kicked two goals.
We had already had lunch before we arrived there.
其结构是"had+过去分词".它的否定句是在had后边加not，变一般疑问句是把had提前。
E.g. I had reached the station before 9：00 o'clock.
I had not reached the station before 9：00 o'clock.
Had you reached the station before 9：00 o'clock？
它通常和before，by the end of 等引导的表示过去的时间状语连用。
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.

虚拟语气
虚拟语气表示一种假设的情况，或一种主观的愿望，即动词所表示的动作或状态并非事实，或不可能实现。英语虚拟语气的形式有下列几种：
If had the time, John would make a trip to China to see the Great Wall.
If I were you, I would give up drinking immediately.
If you should lose, what would you do?
If I were to see her tomorrow, I would tell her the truth.
If you went there next time, you would see what I mean.
If I’d known that it was going to rain, I would never have gone for a walk in the country.
四、虚拟语气的几种特殊用法
省掉if的条件从句结构：
Had you asked me, I would have told you. (=If you had asked me,…)
2.有时虚拟条件不用条件从句而用不定式、分词、介词、名词、连接词或定语从句来表示，如：
A true friend would not do such a thing.
(=If he were a true friend, he...)
(=If there were no water,…)
(=If you hadn’t helped me,…)
3. 有时条件从句中的动作和结果从句中的动作发生的时间不一致，如：
If he had followed the doctor’s advice, he would be quite all right now.
If I were you, I would have gone home.
五、虚拟语气的其他用法
注意：在此结构中that不可省略；should省不省均可。
He suggested that they (should ) stop smoking.
上述动词的名词形式出现时，that 引导的从句仍用虚拟语气。
He made a request that they (should ) stop smoking.
如果that 引导的从句所表达的内容是事实，也可用陈述语气。
He insists that he is right.
It is important that you (should) follow the doctor’s orders.
It is right that you should have done your homework.
I wish I were a pop singer. (=I am sorry I am not a pop singer..)
I wish I had never stopped teaching. (=I am sorry I stopped teaching.)
I wish they’d let us get some sleep.
注意：wish与hope接宾语从句的区别在于：hope表示一般可以实现的希望，宾语从句用陈述语气。wish表示很难或不大可能实现的希望,宾语从句用虚拟语气。试比较：
（1）We hope they will come,(We don’t know if they can come.)
（2）We wish they could come,(We know they are not coming.)
4、as if, as though, would(had) rather(that)引导的从句须用虚拟语气，如：
He acts as if nothing had happened.
I would rather you didn’t tell him.
5、It’s (high) time that…+动词过去式或should+动词原形，如：
It’s time (that) you had a hair cut.
It’s high time (that) we took some action.
虚拟语气用在主语从句中
It is demanded / ne cessary / a pity + that…等结构的主语从句，谓语动词用should 加动词原形，should 可省略。
It is 可用的词有三类that （should）do
suggested, ordered, required, proposed, demanded, requested, insisted等
important, necessary, natural, imperative, strange等
a pity, a shame, no wonder等
虚拟语气用在同位语从句中。
某些表示建议、请求、命令等主观意向的名词后同位语从句需用虚拟语气，其表达形式为(should) ＋动词原形。
这类名词常见的有：advice，suggestion，proposal（提议），order，demand，desire，request，requirement，recommendation （推荐），plan，resolution（决议），idea等。
eg. We are all for your proposal that the discussion ( should )be put off．
虚拟语气用在表语从句中。
某些表示建议、请求、命令等主观意向的名词作主语时，表语从句需用虚拟语气，其表达形式为(should) ＋动词原形。这类名词常见的有：advice，suggestion，proposal，order，demand，desire，request，requirement，recommendation以及plan，idea，resolution等。
eg. My suggestion is that the mayor (should)present the prizes.
虚拟语气用在定语从句中
It is（about ／high）time ＋that sb.did sth/should do sth..
eg. Don't you think it's about time we went home？
注：在this is the first time ／second time that．．．句型中，从句中谓语动词用陈述语气完成时态。
eg.Is this the first time that you have visited Hongkong？
虚拟语气用在让步、方式、目的状语从句中
1．在带有even if/ even though引导的让步状语从句的主从复合句中，主句和从句都用虚拟语气，动词形式与含有非真实条件句的虚拟语气相同。如: Even if he had been ill, he would have gone to his office. 即使生了病，他俩去办公室。2．由as if或as though引导的状语从句表示比较或方式时。从句谓语形式为动词的过去式(be用were)或“had十过去分词”。如: He treated me as if I were a stranger. 他那样对待我，好像我是陌生人似的。She talked about the film as if she had really seen it. 她谈论那部影片，就好像她确实看过一样。
3．虚拟语气用在lest（唯恐、免得），for fear that及in case引导的目的状语从句中。在由lest等引导的目的状语从句中需用虚拟语气，表示“以防，以免”等意思，其谓语动词多由should ＋动词原形构成，should也可省略。
eg. He was punished lest he should make the same mistake again．
虚拟语气用情感语言中
1．虚拟语气在表示客气、遗憾以及祝愿等场合中，使用虚拟语气。
eg.You shouldn't have been following him so closely；you should have kept your distance．
2．If only sb./sth. +时态后退型的谓语
eg. If only I had known the result of the examination.
高考虚拟语气用法详解()
高考虚拟语气用法详解 一·语气概述 和时态语态一样，语气也是谓语动词的一种形式，它表明说话者的目的和意图。英语中有三种语气：陈述语气，祈使语气和虚拟语气。（有的语法书说语气有四种，即还包括疑问语气）。 eg：①He doesn’t see very well in his right eye .他右眼视力不太好。（陈述语气） ②Have they ever been to Australia ?他们去过澳大利亚没有？（疑问语气） ③Please read through the instruction in advance .请先通读说明书。（祈使语 气） 二·虚拟语气概述 在英语中，由于说话人的意图不同，动词需用不同的形式，称为语气。虚拟语气是指说话人表示一种假设的情况，一种愿望，怀疑，推测，请求等，即认为动词所表示的动作或状态并非事实。虚拟语气可用于状语从句，名词性从句，定语从句及其他结构中。 三·非真实条件句中的虚拟语气 真实条件句（遵循主将从现原则） A.由If引导的两种条件句： 非真实条件句（虚拟语气） 以下为If在非真实条件句中虚拟语气的形式和用法： 假设类型If从句主句 与现在事实相反did (be用were)should/would/ could/might do 与过去事实相反had done should/would/ could/might have done 与将来事实相反1)did 2)were to do 3)should do should/would/ could/might do eg：①If I were you ,I would reconsider their advice .如果我是你的话，我会重新考虑他们的意见。（与现在事实相反） ②You would not have caught a cold if you had put on more clothes .如果你多穿了些衣服，你就不会得感冒了。（与过去事实相反）

虚拟语气用法总结及详细解析
虚拟语气用法 英语中的语气分为陈述语气、祈使语气、虚拟语气、疑问语气和感叹语气五类。 1、表示动作或状态是客观存在的、确定的或符合事实的，用于陈述句、疑问句和某些感叹句中。 China is an Asian country. (肯定句) How interesting my stay in China has been! (感叹句) 2、祈使句表示说话人对对方的请求、警告，建议或命令。如: Please come over here. 请到这边来。 Watch your steps! 当心!(走路) 3、虚拟语气表示说话者做出的假设而非事实，或难以实现的情况，甚至表达彻底相反的概念。此外，如需表达主观愿望或某种强烈的感情时，也可用虚拟语气。虚拟语气是由句中的谓语动词的特殊形式表示出来的。如: If I were a bird，I would be able to fly in the air. 如果我是一只小鸟，我就能在空中飞行。 I wish I could pass the examination. 我希望我能通过考试。
If there were a heavy snow next Sunday, we would not go skating. 如果下周日下大雪，我们就不能去滑冰了。 If she were to be here next Monday, I would tell her about the matter. 如果她下周一来这儿的话，我就会告诉她这件事的始末。 4、有时，虚拟条件句中，结果主句和条件从句的谓语动作若不是同时发生时，虚拟语气的形式应作相应的调整。这种条件句叫错综条件句。 ①从句的动作与过去事实相反，而主句的动作与现在或现在正在发生的事实不符。 If I had worked hard at school, I would be an engineer, too.如果我在学校学习刻苦的话，我现在也会成为一个工程师了 If they had informed us, we would not come here now. 如果他们通知过我们的话，我们现在就不会来这里了。 ②从句的动作与现在事实相反，而主句的动作与过去事实不符。 If he were free today, we would have sent him to Beijing. 如果他今天有空的话，我们会已经派他去北京了。 If he knew her, he would have greeted her. 要是他认识她的话，他肯定会去问候她了。 5、当虚拟条件句的谓语动词含有were, should, had时，if可以省略，这时条件从句要用倒装语序，即把were, should, had等词置于句首，这种多用于书面语。 Should he agree to go there, we would send him there.要是他答应去的话，我们就派他去。 Were she here, she would agree with us.如果她在这儿的话，她会同意我们的。 Had he learnt about computers, we would have hired him to work here. 如果他懂一些电脑知识的话，我们已经聘用他来这里工作了。 【注意】 若条件从句为否定句，否定词not应置于主语之后，而不能与were，should，had 等缩略成Weren't，Shouldn't，Hadn't而置于句首。 Had it not been for the bad weather we would have arrived on time. 若不是天气坏，我们就准时到达了。 ②有时省略if后提前的had不是助动词: Had I time，I would come. 假若我有时间，我会来的。(=If I had time…) 6、非真实条件句中的条件从句有时不表达出来，暗含在副词、介词短语、上下文或其他方式表示出来，这种句子叫做含蓄条件句。 ①将条件会暗含在介词短语中，如without…, but for…,otherwise（要不是因为）等 But for his help, we would be working now. (要不是他的帮助，我们还会在工作呢。

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。

If I had got there earlier, I would have met Mr. Li. 3.运用条件句中的虚拟语气时，须注意的几个问题 (1) 有时，虚拟条件句中，主、从句的动作若不是同时发生时，须区别对待。 从句的动作与过去事实相反，而主句的动作与现在或现在正在发生的事实不符。如： If I had worked hard at school, I would be an engineer, too. If they had informed us, we would not come here now. (2) 当虚拟条件句的谓语动词含有wer e, should, had时，if可省略，而将were, s hould, had等词置于句首。如： Should he agree to go there, we wo uld send him there. Were she here, she would agree wit h us. Had he learnt about computers, we would have hired him to work here. (3) 有时，句子没有直接给出假设情况的条件，而须通过上下文或其他方式来判断。如：

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
英语虚拟语气用法详解
英语虚拟语气用法详解 1. 英语语气的概念 英语有三种语气，即陈述语气、祈使语气和虚拟语气。陈述语气用于陈述事实、提出看法或问题等，祈使语气用于表示请求、命令或警告等，虚拟语气则表示假想或主观愿望。如： I like this book the best. 我最喜欢这本书。(陈述语气) Don’t be so careless. 不要如此粗心大意。(祈使语气) I suggest that we should go tomorrow. 我建议我们明天走。(虚拟语气) If you dropped the glass, it would break. 假如你把玻璃杯掉在地上，它会打碎的。(虚拟语气) 3. 虚拟条件句的基本类型 (1) 与现在事实相反：若与现在事实相反，条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”。如： If we left now, we should arrive in good time. 假如我们现在就走的话，我们就会及时到达。 (2) 与过去事实相反：若与过去事实相反，条件从句的谓语用过去完成时(had+过去分词)，主句谓语用“should (would, coul d, might)+have+过去分词”。如： If he had been in that train then, he might have been k illed in that accident. 如果当时他也在那列火车上，他可能就死于那场车祸了。
(3) 与将来事实相反：若与将来事实相反，条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”。如： If he went，would you go too? 如果他去，你也去吗?(大概他不会去) If I asked him，I’m sure he’d help us. 如果我向他提出要求，肯定他会帮助我们。(不过我不打算这样做) 3. 错综时间虚拟条件句 所谓错综时间虚拟条件句即条件从句与主句所指时间不一致，如从句指过去，而主句即指的是现在或将来，此时应根据具体的语境情况，结合上面提到的三种基本类型对时态作相应的调整。如：If you’d listened to me, you wouldn’t be in such tro uble now. 如果你听了我的话，你现在也不会有这样的麻烦了。 If you were in better health, we’d have let you go wit h us. 你要是身体好一点，我们就让你和我们一道去了。 4. 含蓄虚拟条件句 所谓含蓄虚拟条件句即指将条件从句隐藏在上下文一定的短语中的一类条件句。如： Anybody else would have believed you. 任何别人都会相信你的话了。 Without your help, I couldn’t have achieved all this. 要不是有你帮助，我不会取得这些成就。 I would have written before, but I have been ill. 我本想给你写信的，但我生病了。 5. if it weren’t (wasn’t) for与if it hadn’t been for
虚拟语气用法大全
1．虚拟语气在条件句中的用法 （1）若表示与现在事实相反的假设，则条件从句中用过去式，主句中用过去将来式（would，should，could，might + 动词原形）；若表示某事将来实现的可能性不大，则条件从句中用should + 动词原形也可用“were to+动词原形”或用过去式动词。如： 2）若表示与过去事实相反的假设，从句中用过去完成式，主句中用过去将来完成式（should，would，could，might + have + 过去分词）。如： busy． （3）含有虚拟语气的条件状语从句中，如有had，should，were 这三个词的话，在正式或书面语言中可将if省略，再将句子的主语和谓语动词实行全部倒装或部分倒装。如： （4）若主句从句所指的时间不一致，即条件从句表示与过去事实相反，主句表示与现在事实相反；或者条件从句表示与现在事实相反，主句表真实情况，则从句中应采用与具体时间相对应的虚拟形式。如： 2．虚拟语气在宾语从句中的用法 在动词suggest，order，demand，propose，request，command，insist等后的宾语从句中，用虚拟语气（即Should+动词原形或只用动词原形）来表示愿望、建议、命令、请求等。在动词wish /would rather后的宾语从句中，用过去式表示与现在事实不符，用过去完成式表示与过去事实不符。如： 3．虚拟语气在主语从句中的用法 在It is necessary/important/strange/natural；It is requested/suggested/desired/proposed；it is a pity等结构后的主语从句中要用虚拟语气，即Should+动词原形或只用动词原形。如： 4．虚拟语气在表语从句、同位语从句中的用法。 在 suggestion， proposal，idea，plan，order，advice等名词后的表语从句、同位语从句中要用虚拟语气，即should+动词原形或只用动词原形 5．虚拟语气在其他状语从句中的用法 在as if引导的状语从句中，用过去式表示与现在事实不符，用过去完成式表示与过去事实不符；在so that，in order that引导的状语从句中，常用should/would/could/might+动词原形来表示虚拟语气。 6．虚拟语气在定语从句中的用法： 在it is time后面的定语从句中常用过去式表示虚拟语气。 虚拟语气(Subjunctive Mood)这一语法项目是各类英语考试中心测试的重点之一。虚拟语气是一种特殊的动词形式，用来表示说话人所说的话并不是事实，而是一种假设、愿望、怀疑或推测。 Ⅰ用以表示虚拟条件的虚拟语气 ⒈ 用if条件从句表示的虚拟条件，是虚拟条件最普通的方式。 ① 虚拟现在时表示与现在事实相反的假设，其if 从句的谓语形式用动词的过
