虚拟语气虚拟语气表示说话人的主观愿望、猜测、建议或与事实不符的假设等，也可以表示可能性较小的情况或不可能发生的情况，而不是客观存在的事实(表示客观事实要用陈述语气)。
虚拟语气是由句中谓语动词的特殊形式表现出来的。
虚拟语气常用于复合句中，也可用于简单句。
比较：If she asks me tomorrow,I shall do it.如果她明天请求我，我会做的。
(陈述语气，说话人认为请求的可能性大)If she asked me tomorrow, I should do it. 假如她明天请求我，我会做的。
(虚拟语气，说话人认为请求的可能性小或不可能请求)1 虚拟语气的用法1-1 虚拟语气用于条件状语从句中1)表示与现在事实相反的情况If I were/was not busy today, I should go with you.如果我今天有空，我会同你一起去的。

高考英语语法专题复习-动词的语气-虚拟语气
语法复习十：动词的语气——虚拟语气一、语气的定义和种类l、语气：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：(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 not ready. 我们没准备好。
What a fine day it is!多好的天气啊!(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。
请打开门。
(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. 如果我是你，我就学英语了。
May you succeed! 祝您成功！二、虚拟语气在条件从句中的用法条件句有两类，一类是真实条件句，一类是虚拟条件句。
如果假设的情况是有可能发生的，就是真实条件何。
在这种真实条件句中的谓语用陈述语气。
如: If it doesn’t rain tomorrow, we will go to the park. 如果明天不下雨，我们就去公园。
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. 如果他昨天见到你，他会问你这件事的。
(事实上他昨天没见到你，因此也未能问你这件事。
)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。
现将虚拟条件从should 可用于各种人称。
l、表示与现在事实相反的假设和结果。
如: If my brother were here, everything would be all right. 要是我哥哥在这儿，一切都没问题了。
2、表示与过去事实相反的假设和结果。
高考英语二轮专题语法复习虚拟语气语法讲义15if的隐含和省略以及与butfor相关虚拟语气知识点总结
高中英语语法学习/复习讲义虚拟语气语法知识点讲义15【精讲版·全国通用】if的隐含和省略以及与but for相关虚拟语气知识点总结虚拟条件句中if的隐含或省略语言是灵活多变的，表达是丰富多彩的。
有的时候虚拟语气的表现形式也显得非常灵活，比如就说其中的虚拟条件吧——它有时会以if从句来表示，但有时会用某种短语来表示，比如不定式短语、分词短语、介词短语等等。
1. if 的隐含I should be happy to go with you. 如果能与你一起去，我将很高兴。
句中的不定式短语to go with you就是表示虚拟条件的，它相当于if I could go with you。
这句话的言外之意是：可惜我不一定有机会同你一起去。
To have studied harder, you would have passed the examination. 你学习更用功些，你早就考及格了。
句中的不定式短语to have studied harder也是表示虚拟条件的，它相当于if you had studied harder。
句子的言外之意是：可惜你当时没有更用功我，所以你就没有考及格。
Failing this time, what would you do？假若这次失败，那你怎么办？句中的分词短语failing this time表示虚拟条件，相当于if you failed this time。
其言外之意是：尽管失败的可能性很小，但还是有可能会失败，假若失败了，那怎么办？Without your help, we couldn’t have succeeded. 如果没有你的帮助，我们就不会取得成功。
句中的介词短语without your help表示虚拟条件，相当于if you hadn’t given us help。
其言外之意是：好在你帮助了我们，所以我们取得了成功。
I didn’t know that he was a cheat, or else I wouldn’t have believed him. 我不知道他是个骗子，不然我也不会相信他了。

情态动词和虚拟语气第一部分、情态动词一、can/could与be able to1．can/could用来表示“一般能力”；be able to有多种时态,且用来表示在特定条件下的“具体能力”.如：My grandma is over seventy,but she can still read without glasses.They will be able to tell you the news soon.He was able to flee Europe before the war broke out.2．表示允许可用can或could,与may/might意义接近.could可用于现在时,只是语气更加委婉、客气,回答时则一般要用can而不用could.—Could I have the television on?—Yes,you can./No,you can't.二、may与might1．表示允许,意为“可以,许可”,用法基本上同can与could.如：May I use your bicycle?2．表示可能性,意为“也许,可能”.如：According to the weather forecast, it may rain tomorrow.3．may可以放在句首,表示祝愿.如：May good luck be yours!三、must与have to1．must用来表示说话人的主观看法；have to表示客观的需要,强调外界压力,不得已而为之.如：He said that they must work hard.他说他们必须努力工作.(主观上要做这件事)My brother was ill, so I had to call the doctor in the middle of the night.我弟弟生病了,我只得半夜里把医生请来.(客观上需要做这件事)2．表示“不必”,须用don't have to或needn't.must的否定式表示“禁止,绝对不可”.如：You don't have to tell him about it.你不必告诉他那件事.You mustn't tell him about it.你绝不能告诉他那件事.—Must we do it now?我们必须现在做吗？—No, you needn't.不,你们不必.四、shall1．用于第一、第三人称的疑问句中,用来征求对方的意见或请求指示.如：What shall he do next?他下一步干什么呢？2．用于第二、第三人称的陈述句中,表示说话人的意愿,有“命令、警告、允诺、威胁、强制”等意思.如：He shall stay in bed.他必须躺在床上.You shall have it back next week.下周一定还你.He says he won't go, but I say he shall.他说他不去,但我说他必须去.五、will与would1．will用于各种人称,表示“意志、意愿”或“决心”等.如：If you will keep your watch half an hour slow, it is hardly surprising that you are late for your appointments.如果你想要让你的表慢半个小时,你约会时迟到就不足为怪了.2．will表示习惯性的动作,有“总是,惯于”的含义.如：An Englishman will usually show you the way in the street.英国人通常是会在街上给你指路的.3．would可表示过去反复发生的动作.如：On Sundays he would get up early and go fishing.星期天他总是早起去钓鱼.六、should与ought to1．should表示“建议”或“劝告”,有“应该”之意.如：You should learn from each other.2．ought to表示根据某种义务或必要“应当”做某事.如：Everyone ought to obey the traffic regulations.3．should和ought to也可用来表示推测,意为“想必会……”.如：—When can I come for the photos? I need them tomorrow afternoon.—They should be ready by 1200.七、情态动词表示推测1．can用于肯定句中表示客观的可能性,意为“有时会”；用于疑问句中可以表示推测,意为“可能”,有时表示一种惊讶的语气；用于否定句中也可以表示推测,can't意为“不可能”,语气很强烈.It is usually warm in my hometown in March, but it can be rather cold sometimes.我的家乡在三月份通常很暖和,但有时候也会相当冷.Mr. Bush is on time for everything. How can it be that he was late for the meeting?布什先生做什么事情都很准时,他怎么可能开会迟到呢？—Let's visit Tom together, Stephen.—There's no need to do so. He can't be at home, because I saw him board the flight to Beijing this morning.——Stephen,咱们一起拜访汤姆吧.——没必要这样做.他一定不在家,因为今天早晨我看见他登上了飞往北京的航班.2．may/might用于肯定句中可以用来表示不十分肯定的推测,意为“有可能”；用于否定句中也可以表示推测,may not意为“可能不”,表示一种不太确定的语气.The traffic is heavy these days. I might arrive a bit late, so could you save me a place?这些天交通很繁忙,我可能会来晚一点,请你帮我保留个位置好吗？3．must表示推测时只能用于肯定句中,意为“一定,必定”,表示十分肯定的语气(在疑问句中或否定句中要用can/could).—It's the office! So you must know eating is not allowed here.—Oh, sorry.——这是办公室！所以你一定知道这里不许吃东西.——噢,对不起.4．should用来表示推测时意为“应该”,即含有“按道理来说应当如此”的意思.There shouldn't be any difficulty about passing the road test since you have practiced a lotin the driving school.因为你在驾校训练了这么多,通过路考应该没什么困难.八、“情态动词＋have done”结构1．should/ought to＋have done,表示“过去本应该做而(实际)没有做的事情”,含有责备或遗憾的语气,意为“本应该……”.其否定形式为“should not/ought not to have＋done”,表示某种行为本不该发生但实际上发生了.I shouldn't have watched that movie—it'll give me horrible dreams.我本不应该看那部电影——它会令我做噩梦.You ought to have come to the party yesterday, but why didn't you come?昨天你本来应该参加聚会的,可是你为什么不来？2．must＋have done,用于肯定句,表示“过去一定做过某事”,表示一种很有把握的推测.注意,对过去发生的情况的否定推测常用“can't/couldn't＋have done”表示.—Ye Shiwen won two gold medals in London Olympic Games.—She must have gone through tough training.——叶诗文在伦敦奥运会获得了两枚金牌.——她肯定受到严格的训练.—Do you know where David is? I couldn't find him anywhere.—Well. He can't have gone far—his coat's still here.——你知道大卫在哪里吗？我到处找不到他.——大卫的上衣还在这里,因此他肯定没走远.3．needn't＋have done,表示“过去没有必要做某事,但实际上做了某事”.Mark needn't have hurried. After driving at top speed, he arrived half an hour early.马克本没必要那么匆忙.他以最快速度开车,结果早到了半个小时.4．may/might＋have done,表示对过去情况的一种不太有把握的可能性的推测,表示“可能已做了某事……”,否定句表示“可能还没有……”.Sorry, I'm late. I might have turned off the alarm clock and gone back to sleep again.对不起,我迟到了.我可能把闹钟关掉后又睡着了.5．could＋have done表示“过去本来可以做某事,但实际上没有做”；can/could＋have done表示“过去可能做了某件事”.I could have saved the poor rabbit, but I didn't have the right drugs with me at that moment.我本来可以拯救那只可怜的兔子的,可是我当时没有合适的药品.第二部分、虚拟语气一、虚拟语气在虚拟条件句中的用法1.在具体运用中,条件从句中有时可省略if而采用倒装结构.如：Had it not been for your help, we wouldn't have achieved so much.2．介词without/but for、连词but、副词otherwise常用来表示某种假设条件.如：I wouldn't have made such rapid progress without your help.3．有时候从句动作和主句动作发生的时间不一致,这时谓语动词的形式要根据各自的时间来调整.如：If the weather had been more favourable, the crops would be growing still better.二、“should＋动词原形”表示的虚拟语气这一类型常见词有“一坚持(insist)、二命令(order, command)、三建议(advise, suggest, propose)、四要求(request, require, demand, desire)”.以上词及其派生名词所接的名词性从句都使用“(should ＋)动词原形”的虚拟语气.①Jane's pale face suggested that she was ill, and her mother suggested that she(should) havea medical examination.简苍白的脸色表明她病了,她母亲建议她去检查身体.②She insisted that the man had stolen her car and that he(should) be sent to prison.她坚持说那个男人偷了她的车,并坚决要求他坐牢.三、特殊句式中的虚拟语气If only/It's (high) time (that)．..wish/would rather/as if等固定句式要求用相应的虚拟语气表达形式.①I wish I could fly.真希望我能飞.②I would rather you came tomorrow.我宁愿你明天来.③If only I had taken your advice!要是听从了你的建议该多好啊！高频考点一、考查情态动词例1．（2018·北京卷）In today’s information age, the loss of data _________ cause serious problems for a company.A. needB. shouldC. canD. must【答案】C【解析】考查情态动词.句意：在今天的信息时代,数据的丢失有时会对一个公司造成严重的问题.数据丢失造成严重问题是客观上会发生的情况,即“客观可能性”,故该空应用情态动词can.C选项正确.其余情态动词均没有该用法.need需要；should应该,竟然；must必须,肯定.【变式探究】—Can’t you stay a little longer?—It’s getting late.

英语是一门全世界广泛应用的语言。
我们掌握好英语是很有必要的。
我希望英语能学得象母语一样好。
但这看起来似乎是不可能的。
你知道吗？我本来可以学好英语的。
因为有人曾建议我每天背单词，背范文(possible version)，重视语法等等。
但现在是我后悔的时候了。
我想我要是当初听了这些建议的话，现在我的英语一定是很不错了。
要是没有英语该多好啊！如果没有英语，每天我会更快乐！Possible version:
English is widely used in the world. It is necessary that senior students master it well. I wish English would be learnt as well as our mother tongue. But it looks as if it isn’t possible. Do you know? I could h ave learnt English well. Because it was suggested that I recite words and possible versions, pay more attention to grammar and so on. But now it’s time that I regretted it. I think if I had followed these suggestions, my English would be very wonderful now. If only there were no English! Without English I would be happier every day!。
