高中英语 虚拟语气讲解及练习(有答案)
高中英语虚拟语气讲解及练习虚拟条件句就是对现实条件的一种虚拟假设，所假设的条件一般不符合事实或与事实相反或在现实中发生的可能性极小。
根据时间的不同，虚拟条件句可分为三种，即与现在事实相反的虚拟条件句、与过去事实相反的虚拟条件句（1）表示与现在事实相反If I had enough money now, I would lend it to you.（2）表示与过去事实相反If he had taken your advice, he wouldn’t have made such a bad mistake.（3）表示与将来事实相反I would go shopping with you if it were to be Sunday tomorrow.1. 虚拟条件句的倒装在虚拟条件句中，为了强调所假设条件的虚拟性，或突出说话人的一种主观愿望，虚拟条件句可用倒装结构。
虚拟条件句的倒装是通过去掉if，把条件从句谓语中的助动词、情态动词或系动词放在句首实现的。
例如：Had I been（= If I had been ） in that situation， I would not have let the thief escape away with so much money.Should there be （= If there should be） a drought， what should we do at that time ？2. 错综时间条件句有时条件从句的动作和主句的动作发生的时间并不一致，这时谓语动词的形式应根据它所要表示的具体时间来确定。
例如：If we hadn’t been working hard in the past few years ，thing s wouldn’t be going so smoothly.3. 含蓄条件句有时假设的情况并不以条件从句的形式表现出来，而是通过某个介词或介词短语（如：with，otherwise，without，but for，in that position）、上下文或其它方式表现出来。

初中虚拟语气讲解及专项练习与答案(带解析)
虚拟语气讲解语气(mood) 是一种动词形式，用以表示说话者的意图或态度。
英语中的语气有三种：陈述语气、祈使语气和虚拟语气。
直陈语气(indicative mood),表示所说的话是事实。
祈使语气(imperative mood),表示所说的话是请求或命令。
虚拟语气(subjunctive mood),表示说的话不是事实，或者是不可能发生的情况，而是一种愿望、建议或与事实相反的假设等。
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。

例如：If we hadn’t been working hard in the past few years ，thing s wouldn’t be going so smoothly.3. 含蓄条件句有时假设的情况并不以条件从句的形式表现出来，而是通过某个介词或介词短语（如：with，otherwise，without，but for，in that position）、上下文或其它方式表现出来。

虚拟语气讲解与练习
虚拟语气第一部分知识讲解虚拟语气存在于if条件从句中和一些固定结构中,虚拟语气与动词的过去的某种时态形影不离; 虚拟语气是通过谓语动词的变化来实现的;第一节 if 条件状语从句中的虚拟语气一、if 条件状语从句中表示对将来、过去、现在的虚拟If she invites me tomorrow, I shall go to the party.真实条件句如果她明天邀请我参加聚会,我就去.If she invited me, I should go to the party.虚拟条件句说话人认为邀请的可能性较小或不可能If I were you, I should study English. I am not you , so I shall not study English.If I had time, I would attend the wedding. I does not have time, so I will not attend the wedding.You did not take my advice, so you have failed in the examination.If it should rain tomorrow, our picnic would be put off.If it were to rain tomorrow, our picnic would be put off.二、混合虚拟语气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,动词的形式要根据它所表示的时间来调整.If you had worked hard, you would be very tired. 从句说的是过去,主句指的是现在If he had followed the doctor’s advice, he would be quite all right nowIf I were you, I would have gone home.If you had practiced speaking English every day, you would speak English well enough.如果你当初每天都练习说英语的话,你的英语就会说得很好.三.用介词短语代替条件状语从句可以改为条件状语从句Without air, there would be no living things.相当于:If there were no air, there would be no living things.But for your help, I couldn’t have done it.相当于:If you had not helped me, I couldn’t have done it.四、虚拟语气的倒装：如果条件状语从句的谓语中有were, had或should,就可以倒装;将were, had或should放到句首,谓语主语之前, if去掉; 变为”were/had/should+主语”的形式;如果从句没有were, had或should,就不能倒装;If I were to do it, I’d do it some other way.→ Were I to do it, I`d do it some other way.If you should fail, try again.→ Should you fail, try again.If you had been here earlier, you would have seen him.→ Had you been here earlier, you would have seen him.If you came tomorrow, we would have the meeting.这句话不能倒装.而且,在虚拟条件状语从句中,省略了if的倒装形式的句首不能用动词的缩略形式.如:Were it not for the expense, I would go to Italy.但不能说: Weren`t it for the expense, I would go to Italy.第二节固定结构中的虚拟语气一、.It ishigh timethat……句型中的虚拟语气在此句型中,后面的从句的谓语动词常用过去式,.意思为“现在该……的时候了”It is high time that you got married. It is high time that I lost some weight.二、.wish+宾语从句结构I wish it were Spring all the year round. I wish I were Jane.I wish you could go with us. We wish we had arrived there two hours earlier.三.If only句中的虚拟语气If only he were hereIf only I knew moreIf only he had stayed with usIf only I had taken his advice注：if only也可以用于虚拟条件句中;例如：If only I had more money, I could buy a car.四、在would just as soon 宁愿would sooner 宁愿would just rather 宁愿后的宾语从句中,从句谓语用一般过去时来表示现在或将来要做的事情,若谈及过去的动作,用过去完成时;其后不加that;.I`d rather I were in the rain now.Don’t always make noise. I’d rather you kept silent.五、在in case, for fear that, lest等引导的状语从句中,意为“以免”,从句要用虚拟语气;构成should+动词原形,should也可以省略;Take an umbrella with you in case it should rain.六、as if/as though或even if/even though引导的从句中的虚拟语气如果从句中表示的动作发生在过去,则谓语动词用had+过去分词形式;如果指的是现在的状况,则用过去式;指将来则用wouldshould, could+动词原形.这里只看从句动作发生的时间,与主句的时态没有关系. Some metals look at first sight as though they were gold.When a pencil is partly in a glass of water, it looks as if it were broken.She looks as if/though she were ill.He would not resign even if the heaven should collapse.倒塌七.在表示建议,要求,命令等意思的动词request, require, demand, advise, suggest, propose, recommend, command, order , desire, insist,后面的宾语从句中, 谓语动词用should+动词原形,should可以省略,that不能省略.He suggested that we should have a meeting.The commander ordered that the bridgeshould be bombed.八.与表示请求,建议,命令等动词相对应的名词后面的表语从句,同位语从句用虚拟语气.suggesttion,command,demand,desire,request,requirement,insist,advice,propose,order.Our suggestion is that education not be industrialized.表语从句==We suggested that education not be industrialized.He made a request that heshould be allowed to take 3 days off.==He requested that he be allowed to take 3 days off.九.表示建议,请求,命令动词在以下结构中主语从句“It is suggested/ required/ request/ ordered/ advised/ insisted/ demanded that……”用虚拟语气.It was suggested that he should attend the conference.It was requested that the trial should be reported openly.十.在以下结构中主语从句It is important/ necessary/ strange/ desirable/ advisable/ better/essential/ vital / imperative必须的that…句型中.that引导的从句用虚拟语气,should 可以省略,that不能省略.It is essential that there should be enough food and clothing for the winter;It is desirable that your wedding be postponed until next July.第二部分虚拟语气练习题一、if条件句中表示对过去的虚拟1. ________, he would have come to class.A If Mike is able to finish his homeworkB Would Mike be able to finish his homeworkC If Mike could finish his homeworkD If Mike had been able to finish his homework2. __________your advice yesterday, I would have missed the train.A Had I not takenB If I didn`t takeC If I haven`t takenD Provided I didn`t take3.

虚拟语气（讲义及练习）
虚拟语⽓（讲义及练习）虚拟语⽓虚拟语⽓表⽰说话⼈的难以实现的愿望或假设，或者表达建议，命令，劝告等语⽓，不表⽰客观事实。
虚拟语⽓是通过谓语动词的词性变换来实现的。
I.带If条件句的虚拟语⽓1．If条件从句谓语动词形式2．主句谓语动词形式3．需要注意的⼏点重要问题1)should通常只⽤于第⼀⼈称，would可⽤于任何⼈称。
有时候也可⽤might,could。
2)⼀般情况下，主从句所指的时间是⼀致的，但有时候也可能不⼀致，这时候应对主句和从句的时间分别进⾏分析，从⽽确定主从句谓语动词各⾃的正确形式。
1)If you had taken his advice, you wouldn’t be in such a big trouble now.2)If I had finished my homework yesterday, I would go out with you tomorrow.3)当If条件句中含有were, had, should的时候，可以省略if，并将were, had, 或should移到句⾸形成倒装，句⼦的其余部分保持不变。
1)Had she got more money, she would have finished his MA study.2)Should there be a meeting tomorrow, I would come.3)Were I in school again, I would work harder.4)Were I to meet him tomorrow, I should ask him about the result.II.含蓄条件句有些条件句中并不出现if，⽽是使⽤介词短语（but for; with; without等）或是连接词（but; but that; or; otherwise等），此时并不是全句都需要使⽤虚拟语⽓，要根据具体的句意来确定句⼦应该使⽤虚拟语⽓的部分，并按照含有if条件句虚拟语⽓的主句谓语动词变换规则进⾏动词变换。

初中虚拟语气讲解及专项练习与答案(带解析)
初中虚拟语气讲解及专项练习与答案(带解析)虚拟语气是一种动词形式，用来表示说话者的愿望、建议或与事实相反的假设等。
在条件句中，虚拟语气有两种：真实条件句和非真实条件句（也称为虚拟条件句）。
真实条件句所表达的假设是可能发生或实现的，因此条件从句和结果主句都用陈述语气。
例如：“If it doesn’t rain tomorrow。
I will go for a ic.”（假如明天不下雨，我就去野餐。
）虚拟条件句则表达的假设是不可能或不大可能发生或实现的，因此条件从句和结果主句都需要使用虚拟语气。
在非真实条件句中，虚拟语气的用法有以下三种情况：1.与现在事实相反的虚拟条件句：条件从句的谓语动词使用过去式（be的过去式用were），主句的谓语动词使用should（would，might，could）+动词原形。
例如：“If it were not raining。
we should go for a ic.”（如果现在不下雨的话，我们就出去野餐了。
）这句话表达的是愿望，但实际上天在下雨，我们不能出去野餐。
2.与过去事实相反的虚拟条件句：条件从句的谓语动词使用had+过去分词，主句的谓语动词使用should（would，might，could）+have＋过去分词。
例如：“If he had come here。
he might have been able to help you.”（如果他来过这里，他或许能够帮助你。
）这句话表达的是对过去事实的假设，但实际上他没有来这里，他也没有帮助你。
3.与将来事实可能相反的虚拟条件句：条件从句的谓语动词可以使用动词过去式（be的过去式用were）、should+动词原形或were to＋动词原形，主句的谓语动词使用should （would，might，could）+动词原形。
例如：“If it should rain tomorrow。
XXX.”（如果明天下雨的话，我们就取消野餐计划。

虚拟语气讲解及练习(有答案)
虚拟语气讲解及练习虚拟语气在if引导的条件句中的用法三点：从句（条件）主句（目的）表示于现在事实相反的虚拟条件句If+主语+动词的过去式（be用were）If I had time, I would attendthe meeting.主语+would(should couldmight)+动词原型表示与过去事实相反的拟条件句If+主语+had+动词的过去分词If he had hurried ,he couldhave caught the train.主语+would（should couldmight）+have+动词的过去分词表示与将来事实相反的虚拟条件句1、If+主语+动词过去式2、If+主语+were to+ 动词原形3、If+主语+should +动词原形If I were to go abroad ,I wouldgo to America.主语+would（could shouldmight）+动词原型错综时间条件句——主从句时间不一致的情况下的虚拟语气有时条件从句中的动作与主句中的动作，发生的时间不一致，这是动作的形式应根据它所表示的时间加以调整。
If you had followed my advice , you would be better now.If you had studied hard before, you would be a college student now.though引导的方式状语从句中表示与将来事实相反，(表示将来的可能性不大),用would (might, could)+动词原形He acts as if he could win in the game .注意：1.在as if/as though 句中，如果有可能成为事实，用陈述语气。
例：He looks as if he going to be ill.2.as though或as if引导的状语从句，从句主语和主句主语相同时，从句中可省略主语和部分谓语。

二、虚拟语气用在简单句中,表示祝愿,命令.May you be happy. May you have a good time.May the friendship between us last long. Have a good journey!三、虚拟语气用在主语从句中的用法(1) 表情绪观点的形容词或名词也要用虚拟语气.necessary. important. impossible. natural. strange. surprising. funny. right. wrong. better. a pity等。
It is.....that 结构后的主语从句中的谓语动词都要用 should+原型或只用动词原型。
It's natural that he should feel hurt.(2) It is time (about time / high time) that... + (过去时或should + 动词原形)...。
It is high time I went home now. = It is high time I should go home.(3) It be + 过去分词＋that... (should)。
该结构中的过去分词是表示“建议、请求、命令”等词的过去分词：desired, suggested, advised, demanded, requested, ordered, proposed, insisted等。
与以上词语有关的主语从句、宾语从句、表语从句和同位语从句都需要用虚拟语气。
It is desired that the building of the house be completed next month.四、虚拟语气用在宾语从句中的用法1、在wish后的用法a、表示与现在事实相反的愿望，谓语动词用过去式 I wish I had your brains.我希望我有你那样的头脑。
b、表示与过去事实相反的愿望，谓语动词：had+done(动词过去分词） I wish I had known the truth of the matter.c、表示将来难以实现的愿望：谓语动词：should/would + 动词原形I wish I should have a chance again.2、虚拟语气用在希望、要求、建议和命令后的用法一想要(desire)二宁愿(prefer)三命令(order. command)四建议(advise. suggest. propose)五要求(demand. require. request. desire.insist)中，无论主句谓语动词为何种时态，从句的谓语动词都用：“should + 动词原形”或只用“动词原形”He suggested that we (should) take his advice. The police insisted that we (should) hand in the money. 注：（1）insist如果翻译成坚持某种动作才用虚拟语气，如果翻译成坚持某种观点就不用虚拟语气。
He insist he is a student. He insisted that he didn’t steal the knife.（2） suggest意为“建议”才用虚拟语气，意为“暗示、说明”则不用虚拟语气。
His face suggests that he is worried . What he said suggested that he was not the thief.五、虚拟语气在表语从句、同位语从句中的用法在suggestion, proposal, order, plan, idea, advice, decision等需要具体内容解释的名词后要使用虚拟语气，其谓语动词为：should + 动词原形，连接从句的that不能省略。
My suggestion is that we should go there at once. My suggestion that he should go there at once is reasonable. The order was that all the work be finished in two days. The order came that all the work be finished in two days.六、虚拟语气在条件状语从句中的用法1、表示与现在事实相反的情况： if+主语+did/be(were)+其他，主语+should/would/could/might+do+其他（1）If I were you, I would take an umbrella. （2）If I knew his telephone number, I would tell you. （3）If there were no air or water, there would be no living things on the earth.（4）If I had any money with me, I could lend you some. （5）If he studied harder, he might pass the exam.2、表示与过去事实相反的情况： if+主语+had done +其他，主语+should/would/could/might+have done+其他（1） If I had got there earlier, I should/could have met her.（2）If he had taken my advice, he would not have made such a mistake.3、表示对将来情况的主观推测 if+主语+did/should/were to do+其他，主语+should/would/could/might+do+其（1）If he should come here tomorrow, I should/would talk to him.(2) If there were a heavy snow next Sunday, we would not go skating.(3) If it ___ to snow next week, I would not go to visit that mountain village.

(2) Had he known her address, he would have gone to visit her.(3) Had she been here five minutes earlier, she would have seen her old friend.(4)What would have happened ,________ as far as the river bank?A.

We might have died without your help. =We might have died if you hadn’t helped us.Without the sun, nothing would grow. = If there was no the sun, nothing would grow.2) 用or, otherwise, but that, suppose/ supposing (that), provided / providing (that) 等引导的虚拟语气。
You didn’t come yesterday, or you would have seen him.I was very busy last week, otherwise I would have come to see you.Supposing I was still a little child, I would study hard from now on.3) 通过上下文来表示虚拟：这种情况下，需要加以分析。
