虚拟语气语法总结
虚拟语气语法总结
在英语文法中有三种语气，即直述式语气(Indicative Mood)、祈使语气 (Imperative Mood)和虚拟语气(Subjective Mood)，其中前两种我们早已熟悉了，这里则不多谈了，如：How beautiful she is! 则是直述式语气，而Hurry up! Dont hurry up 则是祈使语气。我们主要来看看虚拟语气的主要用法。虚拟语气主要是用来表达一种无法实现的愿望，一种与事实相反的情况，或者将不可能实现的，或可能性很小的事实，假想为事实予以表述。这样的动词结构称为虚拟语气。它主要有三种形式，即与现在事实相反的假设，与过去事实相反的假设，与将来事实相反的假设。它们具体结构如表８－７。虚拟语气的构成种类条件句结构主句结构与现在事实相反动词用过去式be 动词用 wereShould/could＋动词原形would/might＋动词原形与过去事实相反的用had＋过去分词Should/could＋have＋过去分词would/might＋have＋过去分词与将来事实相反动词用过去式were to 加动词原形should 加动词原形should＋动词原形would ＋动词原形虚拟语气其他习惯用法简表种类功用句型例句虚拟语气表示主观愿望主句谓语宾语从句谓语动词I wish we could go to the seaside today、wish现在过去式过去had+过去分词I wish I had gone to the basketball match、将来should+动词原形would+动词原形could+动词原形might+动词原形I wished
I could fly to the moon、I wish you would stay here a little longer、would rather现在过去式I would rather you came to my party tomorrow、表示虚拟比较或方式状语从句从句动词形式She looked after the orphan as if he were here own child、as if, as though, even if 从句与现实相反过去式与过去相反had+过去分词Theyre talking as if they had been friends for many years、与将来相反should+动词原形would+动词原形could+动词原形might+动词原形The man looked worried, as though something would happen to him、that, so that, in order that从句may+动词原形might+动词原形
can+动词原形could+动词原形Turn on the light so that I could see it clearly、 I warned him in order that he might keep away from the danger、表示间接的命令、建议或请求宾语从句用于suggest, propose, insist, desire, demand, request, order, command等之后(should)+动词原形They required that I (should)
go at once、 He suggested that the meeting (should)

problem(should)
be settled as soon as possible、同位语从句They received an order that the work be stopped、在主语从句中表示惊奇、惋惜、理应如此等It is necessary (important, natural, strange 等)
that…主语从句中的动词形式：It is necessary that every member remember these rules、It is a great pity
that he should be so careless、It is suggested that we should get everything ready by tonight、It is a pity (a shame, no wonder 等)
that…should+动词原形It is suggested (requested, proposed 等)
that…表示祝愿或愿望may+动词原形May you succeed!动词原形+宾语Long live the Peoples Republic of China!其他It is time that+主语+should+动词原形It is time that+主语+动词过去式Its time that you should go home now、It is high time that we left、1 语法辨析Incorrect: If I was a girl，I would marry youCorrect: If I were a girl， I would marry you 表示与现在事实相反的虚拟语气时，if条件句中的be动词一律用were，这句话应译为我要是个女孩，我就嫁给你。实际上不可能是个女孩。Incorrect: If I were you I will not worryCorrect: If I were you I shouldnt worry 现在时的虚拟语气主句要用should 或would 加动词原形，这句话应译为我
要是你的话，就没有必要烦恼。要注意这种语态用在这里实际上是想把要讲出的观点表达得婉转些，有礼貌些。Incorrect: God forgives you!Correct: God forgive you! 这里的主语 God 是第三人称单数，之所以动词不加 s 是因为要表达一种祝愿，即人力所不能及的事情，实际上是 forgive前有一助动词should，May 等，但在口语中将其省略了。如：
May you be happy 祝你幸福。Incorrect: If the weather was nice yesterday,we would have gone to the zooCorrect: If the weather had been nice yesterday， we would have gone to the zoo 因句中有 yesterday 一词即表示的是与过去相反的事实，即昨天天气很不好，我们也未去动物园，所以 if 条件句应用 had＋过去分词。Incorrect: If it is was not snowing right now,I will go for a walkCorrect: If it was (were)
not snowing right now， I would go for a walk 虚拟语态 be 动词作助动词时，则可用was来取代were，如 was to。虚拟语态中的动词如果是表示正在进行之中也要用进行时态。Incorrect: If you had taken my advice,you would have been better nowCorrect: If you had taken my advice,you would be better now 这句话的意思是如果你以前要是能听我的忠告的话，你现在就会好多了。其条件句是与过去事实相反的虚拟句，
而主句是与现在事实相反的虚拟句，这在语法书中叫做混合虚拟条件句。例如：
If I had caught that plane， I would be dead now 即：The plane I intended to catch crashed and everyone was killedIncorrect: He were you， he would go home at onceCorrect: Were he you， he would go home at onceCorrect: If he were you， he would go home at once
在虚拟条件句中的if可以省略，但if省略后其句子的结构要采用倒装语序。Incorrect: Supposing your teacher saw you with me What does she think?Correct: Supposing your teacher saw you with me， what might she think? 这句话中没有if条件句，但仍要用作虚拟语态。这里因为有些分词或介词短语，起到了从句的作用。这些短语有：
without， providing, supposing， but
for(you)…Incorrect: To see the girl， you will like herCorrect: To see the girl， you would like her 这里的条件句是用不定式取代了。Incorrect: Im sorry I did have come here by carCorrect: Im sorry I should have come here bycar 这里的条件句被省略了，其意为我真应该坐小车来。同样在句意不会混淆的情况下，主句也有时可以被省略，如：What if we should fail! (我们万一失败了如何)。I f he could do it,
why not? (如果他能做，他怎么会不干呢?)Incorrect: If the earth were (was)
to turn from east to west， I willgive you this car as a giftCorrect: If the earth were(was)
to turn from east to west I would give you this car as a gift 条件句中也常用were to 来表示说话者认为可能性极小或根本不可能的事。Incorrect: If youd have told him early， he would have passed the examCorrect: If you had told him early， he would have passed the exam 非正式口语中往往听见外国人讲：d have＋pp (过去分词)但仍没有人认为它是正确的句子，不易为我们效仿。Incorrect: The little
girl looked as if she would have seena ghostCorrect: The little girl looked as if she had seen a ghost 要注意的是as if 从句中如果用虚拟语气，它的用法要与 if条件句的动词结构相同，即与现在事实相反动词用过去式，be 动词用were，而与过去事实相反的动词用had＋pp (过去分词)。另外更要注意的是，并非所有 as if 从句都要用虚拟语气。如：
Itlooks as if it is going to snow (看天好像要下雪)即是真实条件句。Incorrect: I should have come here early，but I had beenbusyCorrect: I should have come here early but I wasbusy but 是转折连词，其后的句子是真实句，而不是虚拟句。Incorrect: To tell the truth， I wish I know her
address nowCorrect: To tell the truth, I wish I knew heraddress now wish的宾语从句中要用虚拟结构，与现在事实相反的条件动词要用过去式，be动词用were，与过去事实相反的条件动词要用had＋过去分词。如：
I wished I had passed that examIncorrect: His homework was written badlyI wish he will do it better tomorrowCorrect: His homework was written badlyI wish he would do it better tomorrow wish要用来表示对现状不满，希望将来有所改进，则要用would加动词原形。并非wish不能表达真正的祝愿，但是不能接从句，而要用双宾语，或不定式，如：I wish you luck (双宾语)I wish you to be a good studentI wish to see her at onceIncorrect: I wish it will not be another failureCorrect: I hope it will not be another failureCorrect: I wish it would not be another failure 要注意 hope 与 wish 的不同用法。2 例题解析［例1］If he
on tourists for his business， he would have to close his shop
A depends
B will depend
C depended Dhas depended ［答案］
C、这是与现在事实相反的假设。应译为：如果他仅靠旅游来做生意的话，他早就要关门了。［例2］Had she been younger， she
more beautiful
A had been
B might have been
C might be
D would be ［答案］
B、因其条件句是省去if的与过去事实相反的假设。［例3］If you
that TV play last night， you wouldnt be sleepy
A havent watched
B didnt watch
C hadnt watched
D wouldnt have watched［答案］
C、因是与过去事实相反的假设。应译为：昨晚你要是不看那个电视剧，你现在也不会这么困倦了。这是混合虚拟句，主句是与现在事实相反的虚拟。［例4］If it
tomorrow， we will not go for the picnic
A will rain
B had rained
C rained
D rains［答案］
D、因其主句是将来时，所以条件句应用一般现在时表示将来。所以要注意的是有些真实条件句并没有虚拟的含意，不要乱用虚拟语态。［例5］We had hoped that we
go home at once
A did
B will
C /
D would［答案］
D、 had hoped 用来表达对过去未能实现的愿望，其宾语从句要用would加动词原形。［例6］I want to see her todayId rather you
A didnt
B do not
C dont
D do［答案］
A、 d rather 其后如直接接动词则用动词原形。如加宾语从句则从句中谓语动词要用过去式。［例7］It is very late，Its time
A we have left
B we will leave
C we left
D we leave［答案］
C、要注意It is (high/about)
time 其后可接 for something, 如：It is time for supper、或 for somebody to do something 也可接从句，但从句中的谓语动词要用过去式，有时也可用should加动词原形，但should不可省略。［例8］These typewritten papers are very neatI wish I
type too， but I dont know how
A can
B may
C could
D will［答案］
C、因wish在从句中表示与现在相反的虚拟，所以要用would或could。［例9］It is important that he
this work at once
A do
B does
C did
D will do［答案］
A、虚拟语气可以用来表示要求、建议、提议、命令、意愿等。在Itis ＋形容词(过去分词)
＋从句的结构中，从句中的谓语动词要用should加动词原形，其should在美语中经常省略。这样的形容词有：important， necessary， strange， natural。这样的过去分词有：
demanded, requested, suggested， required，recommended。［例10］The teacher ordered that the students
her
A obeys
B obeyed
C obeying
D obey［答案］
D、因带有命令要求口气的动词其宾语从句中的谓语动词也要用should加动词原形。其should在美语中则被省略。这样的
动词有：ask， advise， demand， desire， insist， order，recommend, require， request，suggest…［例11］She rejected my suggestion that she
her son the next week
A met
B will meet
C meet
D would meet［答案］
C、因同位语从句的谓语动词要用should加动词原形。这是因为其前面的名词是由［例10］中的那些表示愿望、命令、建议的动词转化而来的。［例12］Whats the matter with her?I dont know but she looks
shed lost her boy friend
A that
B so that
C as
D as if［答案］

today， he would get there by the weekend
A Would he leave
B Was he leaving
C Were he to leave
D If he leaves［答案］

A was able
B were able
C had been able
D should be able［答案］
C、在wish从句中要表达对过去事实的一种不可能实现的愿望时，要用 had 加过去分词。［例16］Jane appears as though she
the secret
A knows
B has known
C is knowing
D had known［答案］
D、这是对过去事实的假设，as though ＝ as if［例17］Her pale face suggested that she
ill， and the teacher wanted to send her to the doctors
A be
B should be
C were
D was［答案］
D、因 suggest 作建议讲时其宾语从句要用虚拟语气，但是作暗示则不要用虚拟语态。［例18］Without electricity，human life
quite different today
A is
B be
C will be
D would be［答案］
D、由 without 介词短语引出的虚拟条件句，其主句如表示与现在事实相反，则用should， would加动词原形。［例19］He insisted that he
do it alone
A wanted to
B want to
C should want to
D wants to ［答案］
A、如果主句的主语与宾语从句的主语是同一个人时，insist从句中则不宜用虚拟语态。［例20］If it
so hard， wed go home
A isnt raining
B doesnt rain
C werent raining
D isnt going to rain［答案］
C、因is raining的过去时应为was raining，但在虚拟条件句中最好用were raining。
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。
虚拟语气语法讲解与习题
虚拟语气 一．语气的分类： 二．虚拟语气的用法： （一）虚拟语气在if条件句中的用法： ---If I were you, I would give it up. (与现在事实相反) ---If I had taken his advice, I would not have made such a mistake. (与过去事实相反) ---If she came/should come/were to come, I could ask her for help. (与将来事实相反) 2．特殊用法： ①错综时间虚拟条件句：条件从句与主句所指时间不一致，主从句的谓语动词要根据假设的时间来定。 ---If you had followed the doctor’s advice, you would be much better now. ②if条件句虚拟倒装：可以把if从句中的should, were, had置于句首，省略if构成倒装。 ---Were I you, I would give it up. ---Had I taken his advice, I would not have made such a mistake. ---Should she come, I could ask her for help. ③含蓄虚拟条件句：有时假设的情况并不以if引导的条件从句表示出来，而是通过一个介词短语或其他方式表示。常用的词或短语有：without, but for, otherwise, or, but等。 ---Without/But for your help, I could not have succeeded. ---I should have returned the book last week, but I was too busy. （but后为真实情况） ---He was ill, otherwise/or he would have helped us. （otherwise/or前为真实情况） ④特殊的if句虚拟：If it were (had been) not for…“要不是…” ---If it were not for peace, we could not be living a happy life. ---If it had not been for your help, I would have failed. （二）虚拟语气在名词性从句中的用法： 1．一些表示坚持，命令，建议，要求的词用于名词性从句中时从句的谓语动词用虚拟（一坚持，二命令，三建议，四要求） ---Our teacher suggested that we (should) study hard. (宾语从句) ---That we (should) study hard was our teacher’s suggestion. (主语从句) ---It was suggested that we (should) study hard. (主语从句) ---Our teacher’s suggestion was that we (should) study hard. (表语从句) ---Our teacher gave us a suggestion that we (should) study hard. (同位语从句) ★suggest表示“暗示”，insist表示“坚持说”时不用虚拟。 ---His pale face suggested that he was ill. ---The old man insisted that I had stolen his money.
英语虚拟语气语法归纳总结
虚拟语气: 表示说的话不是事实，不可能发生或者说可能性很小的情况，表达一种愿望、建议、假设。 if were/did, would do if had done, would have done if were to do/should do, would do 举例： If I were you, I would do nothing about it. If you had taken your teacher’s advice, you wouldn’t have made such a mistake. If it were to/ should rain tomorrow(表示降水率很低)，they wouldn’t go shopping. 附注： 虚拟语气，条件状从倒装 状语从句中，去掉if,提前were/ had/ should 如：If I were you, I would give up. →Were I you, I would give up If you had taken the advice, you would have…. →Had you taken the advice, you would have… If the world shou ld come to an end,…… →Should the world come to an end…… 另外，without, but for, otherwise构成的条件状语从句中，也有含蓄的虚拟语气But for the popularization of electricity, we would lead a whole different life today. (popularization 普及，publicity 宣传) Without your help, I would have failed. We’ll go earlier, otherwise we wouldn’t get a seat.（表示可能性小）
英语虚拟语气讲解
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 虚拟条件句的三种基本类型: 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”： If you took a taxi，you’d get there quicker.如果你坐出租车去，你可以快一点到那里。(但你不坐) If I knew her number I could ring her up. 要是我知道她的电话号码，我就可以给她打电话了。(可惜我不知道) 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, could, might)+have+过去分词”：If I’d left sooner，I’d have been on time.要是我早点动身，我就准时到了。(但我动身太迟了) If we had found him earlier we could have saved his life. 要是我们当时早点找到他的话，我们就可以救活他。(可惜我们找到他太晚了) 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”： 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) 大多数的虚拟条件句属于上面三种情况的一种，但并不排除存在条件和 后果中，一个和现在情况相反，另一个和过去情况相反，例如：If you had followed what the doctor said, you would not have been so painful now. 这个句子在高中出现频率颇高。 但是，如果后果用了虚拟语气，而条件却用陈述语气，这种用法是错的。 2. 除了表示虚假条件外，if从句还可以表示对将来的推测，由于是 将来还没有发生的，所以谈不上是真实的还是虚假的，只能说这个事情 发生的可能性有多大。一般情况下，可以用陈述语气的if从句来表示对

高中英语语法讲解--虚拟语气 1. 语气的定义和种类 （1）语气的定义 语气是动词的一种形式，它表示说话人对某一行为或事情的看法和态度。 （2）语气的种类 A. 陈述语气 表示动作或状态是现实的、确定的或符合事实的，用于陈述句、疑问句和某些感叹句。 We are not ready. Did it rain all day yesterday? What a fine day today！ B. 祈使语气 表使说话人的建议、请求、邀请、命令等。 Be careful. Don’t forget to clo se the window. Open the door, please. C. 虚拟语气 表使动作或状态不是客观存在的事实，而是说话人的主观愿望、假设或推测等。 2. 虚拟语气 一. 虚拟语气在条件句中的应用 学习虚拟语气在条件句中的用法之前我们必须清楚条件句的种类：条件句有真实条件句与非真实条件句(或称虚拟条件句)两种。真实条件句所表的假设是可能发生或实现的，句中的条件从句与结果主句都用陈述语气。如： If it doesn’t rain tomorrow, I will go for a picnic. 假若明天不下雨，我就去野餐。 Oil floats if you pour it on water. 你如把油倒在水里，油就浮起来。 虚拟条件句所表的假设则是不可能或不大可能发生或实现的，句中的条件从句与结果主句皆须用虚拟语气。 1. 与现在事实相反的虚拟条件句，条件从句的谓语用动词的过去式(be的过去式用were), 主句的谓语用should （would, might，could）+动词原形。 如： If it were not raining, we should go for a picnic.如果现在不下雨的话，我们就出去野餐了。 （事实是：天在下雨，我们不能出去野餐。表示愿望。） If he came here, he might be able to help you. 如果他来这，他就能够帮助你了。 （事实是：他没来这，他不可能帮助你。表示对他的良好印象。） 2. 与过去事实相反的虚拟条件句，条件从句的谓语用had+过去分词，主句的谓语用should （would, might，could）+ have ＋过去分词。 如：She would have gone to the party if she had been invited.
虚拟语气用法总结
虚拟语气的用法总结 语气：语气是动词的一中形式，它表示说话人对某一行为或事情的看法和态度。 语气的种类： （1）陈述语气表示动作或状态是现实的，确定的或符合事实的，用于陈述句，疑问句和某些感叹句。如We are ready. What a fine day it is! （2）祈使语气表示说话人的建议，请求，邀请，命令等。如Open the door, Please. 应注意以下几点： 1.主语通常是第二人称you，但多不出现，动词用原形，否定用do not 或者don’t 加动词 原形（或be）如Be careful next time. Don’t smoke here. 2.有时为了强调，主语也可以出现，而且可以是第三人称，谓语动词不加-s或者-es如You be quiet. He stand up. 3.祈使语气可以用do加强语气如Do come to see this Sunday. 4.在Let’s 的祈使句后，疑问部分通常用shall we；在Let us后，疑问部分用will you 如Let’s go out for a walk after supper，shall we? /Let us clean our classroom, will you? 5.祈使句与连词and连用时相当于一个条件句，而and之后则是表示结果。如Think hard and you will have a good idea. （3）虚拟语气表示动作或状态不是客观存在的事实，而是说话人的主观愿望，假设或推测等。如If I were you, I should study English. 一．虚拟语气在条件从句的用法 条件句有两类，一类是真实条件句；一类是非真实条件句，也就是虚拟条件句。 如果假设的情况是有可能发生的，就是真实条件句，谓语要用陈述语气。如If it doesn’t rain tomorrow, we will go to the park. 如果假设的情况是过去或现在都不存在的，或将来不大可能发生的，则是虚拟条件句。如If he had seen you yesterday, he would have asked you about it. 在含有虚拟条件句的复合句中，主句和从句的谓语都要用虚拟语气，列表如下： 例如：If he were here, everything would be all right. If her mother had taken the doctor’s advice, she would/might have got well earlier. If it were to rain tomorrow, the match would be canceled. 有时候省略if，采用局部倒装语序。把had /should/were 等动词（不包括行为动词）移到从句的句首。例如：
高中英语 第二册 语法总结 虚拟语气
新概念英语第二册语法总结：虚拟语气 虚拟语气分三种情况来掌握： 1、虚拟条件句。 2、名词性虚拟语气。 3、虚拟语气的其他用语。 一、虚拟条件句： 条件状语从句是非真实情况，在这种情况下要用虚拟语气。 1、条件从句与现在事实不一致，其句型为： If 主语＋过去时，主语＋should(could, would, 或might)＋动词原形，如： If I were you, I would study hard. If it rained, I would not be here now. 2、条件从句与过去事实不一致，句型为： If 主语＋had＋过去分词，主语＋should(could, would, 或might)＋have＋过去分词，如：If the doctor had come last night, the boy would have saved. If I had not studied hard, I would have failed in the exam last term. 3、条件从句与将来事实不一致，句型为： If 主语+should(were to, 过去时)＋do，主语＋should(could...)＋原形do，如： If it should rain tomorrow, we would stay at home. If I were to go to the moon one day, I could see it with my own eyes. If you missed the film to night, you would feel sorry. 注意问题： 1、If条件句中绝对不可出现"would"。 2、根据句中的时间状语，有时可能出现“混合虚拟”的情况，即主句可能是现在的情况，条件句也许是发生在过去的情况，但都是遵守上述句型。 3、在条件句中如果出现were, had, should可省去if，将主语与这些词倒装，例如： Had the doctor come last night, the boy would have saved. Were I to go to the moon one day, I would see it with my own eyes. Should it rain tomorrow, we would stay at home.
英语语法专项：虚拟语气用法详解及练习(附答案)
虚拟语气用法详解 一、条件句中的虚拟语气 1. 条件句中虚拟语气的形式 从句中提出一种与客观现实不相符或根本不可能存在的条件，主句会产生的一种不可能获得的结果。条件句中 的虚拟语气根据不同的时间有三种不同的形式。 2. 条件句中的虚拟语气的举例 (1) 将来时的条件句中的虚拟语气。如： If he should go to Qing Hua University, he would make full use of his time. 如果他要上清华大学的话，他就会充分 利用他的时间了。 If he were to come here, he would tell us about it. 如果他要来的话，他会通知我们一声。 (2) 现在时的条件句中的虚拟语气。如： If he were free, he would help us. 要是他有空的话，它会帮助我们的。 If he studied at this school, he would know you well. 如果他在这所学校学习的话，它会对你很熟悉。 (3) 过去时的条件句中的虚拟语气。如： If I had seen the film, I would have told you about it. 我如果看过这场电影，我会把电影内容告诉你了。 If I had got there earlier, I would have met Mr. Li. 如果我早点到那儿，我就会会到了李先生。 3. 运用条件句中的虚拟语气时，须注意的几个问题 (1) 当从句的主语为第三人称单数时，谓语动词若是系动词be 时，可用was 代替were。但在倒装虚拟结构及if I were you, as it were 中，只能用were。如： Were I ten years younger, I would study abroad. 要是我还年轻十岁的话，我会去国外学习。 If I were you, I would try my best to grasp the chance. 要是我是你的话，我要尽力抓住这次机会。 (2) 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。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。如： 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，我现在也会使工程师了 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。
考研英语语法虚拟语气解析(一)
考研英语语法虚拟语气解析（一） 虚拟语气是谓语动词的一种形式，用来表示假设，或用来表示命令、建议以及说话人的主 观愿望，有时也可以使语气缓和、委婉。虚拟语气作为一重点语法，在各类考试中占有相当 大的分值，所以理解该语法，不管对于考试，还是在日常应用中都有相当大的作用，本节将 就考试重点作详细讲解。 一、虚拟语气的用法 常用于条件句中，表示与现在、将来、过去相反的假设，表示与现在、将来、过去相反假设时，主句与从句谓语动词的变化形式，现以动词do为例说明。 主句从句现在would/should/could/might + do be 宀were/do 宀did 将来 would/should/could/might + do were to + do/should + do （只能用should）过去 would/should/could/have done had done注：有些语法书中在"与将来相反假设”的条件从句中也有do i did，这样就和“与现在相反假设”的主句、从句完全相似，其主要区别在于各自的时间状语上，另外如果在“与将来相反假设”的条件从句中出现should+ do，那么主句 中就避免使用should+do，可以用would/could/might+do。 例句：If you were to exam ine the birth certificates of every soccer player in 2006 s World Cup tour name nt, you would most likely find a no teworthy quirk. （选自2007 年Text 1） 分析：该句是复合句。 译文：假如你去调查2006年世界杯上每位足球运动员的出生证明，你很可能会发现一 个值得注意的现象。 例句：If that happe ned, passi on ate con sumers would try to persuade others to boycott products, putting the reputation of the target company at risk.（选自2011 年Text 3）分析：该句是复合句，表示与现在相反的假设。其中，分词短语putting the reputation of the target company at risk在句中作状语，表示结果。 译文：这种情况一旦发生，充满激情的消费者会尽力说服他人抵制产品，从而使目标企业的声誉处于危 险境地。 例句：Everything here would have been destroyed utterly , if his wife hadn t called the fire brigade. 分析：该句是复合句。 译文：要不是他的妻子给消防队打电话，这里的一切就被彻底地破坏了。 二、混合式虚拟语气 有时条件从句和主句时态不一致，可以根据主句、从句动作发生的时间分别运用相应的 虚拟语气。 例句：He would be studying at the university now if he had passed the entrance exam in ati on.
实用英语虚拟语气的解析及其用法讲解
实用英语虚拟语气的解析及其用法讲解 在当前英语语法当中，有一些学生总结的几个难点语法，其中之一就是虚拟语气，怎样判断出句子使用了虚拟语气，是哪一种形式的虚拟语气是学生无法清楚掌握的难点。本文从虚拟语气的定义到各种形式都进行了详细的讲解和分析，并针对各种形式的用法都进行了分析和举例，讲解明白，以帮助学生们能更好地了解和掌握英语语法中这个难学的语言现象。 标签：英语虚拟语气；定义；用法；分析及举例 一、虚拟语气的定义（Subjunctive Mood） 在我们了解什么是虚拟语气前，大家首先要弄清楚英语的语气表达，也就是英语学习中我们都会用到哪些语气。英语中的语气（Mood）可以分为：1The Indicative Mood（陈述语气）；2The Interrogative Mood（疑问语气）；3The Imperative Mood（祈使语气）；4The Subjunctive Mood（虚拟语气）4类。陈述、疑问、祈使语气在本文中就不再过多阐述。而我们在这里重点讲解虚拟语气。什么是虚拟语气呢？虚拟语气用来表示假想，而不表示客观存在的事实，所说的是一个条件，不一定是事实，或与事实相反。虚拟语气通过谓语动词的特殊形式来表示。虚拟语气表示说话者所说的话并非事实，或难以实现的，甚至表达相反的概念。另外表示主观愿望或表达某种强烈的感情时，也用虚拟语气。 二、虚拟语气的判断及用法 （一）if条件状语从句中虚拟语气的判断 if条件状语从句有真实条件句和非真实条件句。假设条件可以实现的句子为真实条件句，反之为非真实条件句，要用虚拟语气。其形式分为以下三种：1与过去事实相反的假设。结构为：从句的谓语动词用“had+过去分词”，主句用“should（would，could，might）+have+过去分词”。 2与现在事实相反的假设。结构为：从句的谓语动词用过去式，系动词用were，主句的谓语用“should（would，could，might）+动词原形”。 3与将来事实相反的假设。结构为：从句的谓语动词用“should（wereto）+动词原形”，主句用“should（would，could，might）+动词原形”。 （二）宾语从句中的虚拟语气 1wish后接宾语从句中的虚拟语气：根据从句的意义来判断 A：表示与现在和将来事实相反的愿望，从句谓语动词用过去时态。例如：

1语法辨析 In correct: If I was a girl, I would marry you Correct: If I were a girl, I would marry you 表示与现在事实相反的虚拟语气时，if条件句中的be动词一律用were，这句话应译为我要是个女孩，我就嫁给你。实际上不可能是个女孩。 In correct: If I were you I will not worry Correct: If I were you I should n't worry 现在时的虚拟语气主句要用should或would加动词原形，这句话应译为我要是你的话，就没有必要烦恼。要注意这种语态用在这里实际上是想把要讲出的观点表达得婉转些，有礼貌些。 In correct: God forgives you! Correct: God forgive you! 这里的主语God是第三人称单数，之所以动词不加s是因为要表达一种祝愿，即人力所不能及的事情，实际上是forgive前有一助动词should, May 等, 但在口语中将其省略了。如：May you be happy祝你幸福。 In correct: If the weather was nice yesterday, we would have gone to the zoo Correct: If the weather had been nice yesterday we would have gone to the zoo
虚拟语气语法讲解
虚拟语气语法讲解 虚拟语气 英语句子中谓语动词的语气有三种： 1. 直陈语气（The Indiative d）直陈语气用于直截了当地陈述事实、描述状态： He has published quite a nuber f essays this year .他今年已发表了好几篇论。 2. 祈使语气（The Iperative d） 祈使语气用于提出请求、命令、建议或是劝告等： ait utside until yu are asked . 请在外面等候，请你进再进去。 Lets ust take a break, shall we ? 我们休息一会儿，好吗？ 3. 虚拟语气（The Subuntive d） 虚拟语气用于表示主观愿望和假设的虚拟情况。虚拟语气不太顾及事实的存在，它表现出说话人的主观因素比较多。所以说话人所讲的内容往往是与事实相反的；或是其实现的可能性微乎其微，甚至于没有实现的可能性。当然，有时为了使说话的语气客气、缓和、委婉，也使用虚拟语气。例如： I wish yu were re areful .但愿你更细心一些。 If I had re ney, I wuld buy a bigger apartent.
我要是有再多一点钱，我就买一套更大一些房子。 uld yu ind shutting the dr ? 劳驾您把门关上。 一、虚拟语气在条件状语从句中的构成和用法 1. 表示一种与过去事实相反的假设情况，条件从句中的谓语动词要用“had+过去分词”，主句中的谓语动词要用“wuld / shuld / uld / ight+have+过去分词”。如： If yu had e here yesterday, yu wuld have seen hi. 如果你昨天到这里，你就会看见他了。 2. 表示一种与目前事实相反的假设情况，条件状语从句中的谓语动词要用一般过去式(be动词常用were)，而主句中的谓语动词则要用“wuld / shuld / uld / ight+动词原形”。如： If I had his telephne nuber, I wuld all hi nw. 如果我有他的电话号码，我现在就打电话给他。 If I were yu, I wuld nt tell hi that. 如果我是你，我就不把那件事告诉他。 3. 表示与将的事实可能相反的假设情况时，条件状语从句中的谓语动词要用：1) shuld+动词原形，或2) 一般过去式，或3) were+不定式，主句中的谓语动词要用“wuld+动词原形“。如： If it snwed trrw, any rps wuld die f ld. = If it were t snw trrw, any rps wuld die f ld. = If it shuld snw trrw, any rps wuld die f ld. 如果明天下雪，许多庄稼都会冻死。 4. 有时候，条件和结果不是指同一个时间，这时，应根据上面谈到的几种情况，使用相应的形式，这种虚拟语气
语 法 讲 解 ——虚拟语气
语法讲解 ——虚拟语气 英语中有三种不同的语气：陈述语气，祈使语气和虚拟语气。虚拟语气表示动作或状态与事实相反，或不可能发生的情况。 1. 表示与现在事实相反或不可能发生：条件状语从句：一般过去时（虚拟语气中be→were）主句用：would(should, could, might)+动词原形。 If we had time now, we would read it again. If I were you, I would work hard. 2. 表示与过去事实相反或不可能发生：条件状语从句：had+过去分词；主句：would(should, could, might)+have+过去分词。If he had taken my advice, he would have succeeded in the test. If I had known your telephone number then, I would have called you. 3. 表示与将来的事实可能相反或不可能发生：条件状语从句： ①一般过去时②should +动词原形③were to+动词原形；主句：would(should, could, might)+动词原形。 If it should rain, the crops would be saved. If it were to snow tomorrow, they would not go out. P.S 虚拟条件句的特殊情况
(1). 混合/错综型虚拟语气 当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时，称为‘错综条件句’，动词的形式要根据它所表示的时间作出相应的调整。 If you had followed my advice, you would be better now.(从句说的是过去，主句是现在) If I were you, I would have taken his advice.(从句是现在，主句是过去) （2）省略if的虚拟语气 如果从句中含有were/ should/ had时，则可以把这三个词置于句首，省略if.采用倒装语序。 If it should happen, what would you do? →Should it happen, what would you do? If he had recognized me, he would have come over. →Had he recognized me, he would have come over. (3) 含蓄虚拟条件句 有时候假设的情况不以if引导的条件从句形式表现出来，而是通过一个介词短语，连词或其他形式表示。常用的词或短语有：without, with, but for(要是没有), otherwise, or, but等。Without your help(=If we had not had your help), we could not have succeeded.

虚拟语气用法归纳 虚拟语气主要指的的是带有非真实条件状语从句的复合句，表达的是说话人的遗憾后悔的语气，愿望以及建议，命令，要求等等的情感，往往说的是与事实相反或者没办法实现改变的东西。虚拟语气主要表现为在对过去现在或者将来的情况做出假设后，有可能出现的情况。 虚拟语气的内容主要有三大模块，第一模块就是涉及到条件从句部分的内容。这一部分的虚拟语气主要体现在三个方面：基本用法，各自为政，以及含蓄之美。 下表就是条件从句虚拟语气的基本用法： 通常，在上面表格里反映的是非真实条件句的虚拟语气模式，从句和主句的谓语动词时间是一致的，如果两者时间不一致，此时就是混合型虚拟语气。混合型虚拟语气的使用要求“各自为政”，即从句和主句根据各自假设的时间不同，采用上面表格中对应的的谓语动词形式。 如何“各自为政”呢这就像是数学里的排列组合，一边有三种情况，交叉一搭配就出现了好多种情况。不管怎样，我们要遵循一个原则，就是“各自为政”。例如，从句是对过去情况的假设，而主句则是对现在情况的假设，那我们在使用时，从句就用过去完成式，而主句要用
would/could do的形式。当然，也不是所有的AB配就是合理的，有时候在具体语境下，会出现矛盾的情况，这时我们就要结合要表达的意思来 判断他们是对什么情况的假设，选择合适的形式。一般而言，主句的假 设时间会发生在从句的假设时间之后。因为是有这么一个条件才会出现 主句的现状。因此在此类的完成句子练习中，我们要特别提醒注意时间 状语的暗示 1. If I had seen you, I would not be so worried now. (从句是对过去的假设，主句是对现在的假设) 2. If you had not watched television so late last night, you would not be so sleepy now.( 从句是对过去的假设，主句是对现在的假设) 3. If I were you, I would seize the chance to go abroad. (从句和主句都是现在的假设) 4. Had you followed the doctor’s suggestion, you would be fine now.( 从句是对过去的假设，主句是对现在的假设) 5. If I had made some money last summer, I would go on holiday next month.( 从句是对过去的假设，主句是对将来的假设) 6. You didn’t let me drive. If we had driven in turns, you wouldn’t be so tired now. (从句是对过去的假设，主句是对现在的假设) 7. If Jack hadn’t met Rose on his voyage, he would be alive now. (从句是对过去的假设，主句是对现在的假设)
