高中英语虚拟语气讲解及练习题(附答案)
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。

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.

虚拟语气解析以及练习题答案详细解答
虚拟语气解析及练习与答案详解虚拟语气一、虚拟语气的运用练习题及答案解释The millions of calculations involved, had they been done by hand,______all practical value by the time they were finished.A.could loseB. would have lostC. might loseD. ought to have lost解析：这个句子中含有一个省略if，把助动词提前到主语they之前的虚拟条件句，该条件句表示对过去情况的假设，而主句中by the time they were finished表明主句也应该是对过去发生的情况的假设，因而应该选（B）would have lost为正确答案。
2. Had Paul received six more votes in the last election, he our chairman now.A. must have beenB. would have beenC. wereD. would be解析：这道题目是一个混合虚拟语气的句子。
条件句省略了if，把助词had提前到主语前面，表示对过去情况的假设，而主句中now表明了对现在情况的假设，所以应选would(should, could, might)+动词原形这种表达形式。
四个选项中只有（D）是正确表达形式，故为正确答案。
3. If you Jerry Brown until recently, you’d think the photograph on the right was strange.A. shouldn’t contactB. didn’t contactC. weren’t to contactD. hadn’t contacted解析：until recently，因此（D）是正确答案，而主句是隐含的对现在情况的假设，该句是一个混合虚拟条件句。
高中英语虚拟语气讲解及练习题(附答案)
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。

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。
1)But for the rain, we should have a pleasant picnic. （主句与现在事实相反）2)Without air, there would be no living things. （主句与现在事实相反）3)With favorable wind, we might have got there two days before. （主句与过去事实相反）4)I would have given you more help, but I was really very busy. (主句用虚拟语气，but分句用陈述语气)5)I would go abroad but that I don't have enough money. (主句用虚拟语气；but that分句用陈述语气)6)She eats too much every day, or she would be thinner. (主句用陈述语气；or分句用虚拟语气)7)I was busy, otherwise I would have given you more help. (主句用陈述语气；otherwise分句用虚拟语气)III.虚拟语气在其他从句或句型结构中的运用1．It is (high；about) time (that) … 是该。
的时候了That引导的从句中的谓语动词多用过去式或过去进行时，或者是should; could + do (should; could不能省略)1)It is high time that we left.2)It is about we should take further actions.2．would rather | would just as soon +that … (宁愿。
)that从句谓语动词用过去时表示现在或将来；用过去完成时表示过去。
注意would有时候会被缩写为’d。
1)I would rather you paid me now.2)I would rather you painted the wall next time.3)I would rather you had not done that.3．If it were not for … 如果没有。
If it had not been for … 如果当时没有在If it were not for中，主句谓语动词用should; would + do在If it had not been for中，逐句谓语动词用should; would have + done1)If it were not for the rain, the crops should die.2)If it had not been for your help, I would have failed.4．在表示要求，建议，命令等的主语从句，宾语从句，同位语从句，表语从句中在上述四种从句中，从句的谓语动词要采用(should) + do。
引起这类意思的从句的动词常用的有：suggest (suggestion), require (requirement), order(order), insist (insistence), advise (advice), propose (proposal), command (command), demand (demand), request (request), desire (desire)等。
下面以suggest为例，分别举例说明在这四种从句中的具体使用。
1)He suggests that the meeting should be postponed.2)It is suggested that the meeting should be postponed.3)The suggestion that the meeting should be postponed was rejected.4)His suggestion is that the meeting should be postponed.另外，在此种情况下的主语从句中，还应该注意下列结构：It is necessary that …(should) do…此处和necessary用法相似的形容词还有important; natural; desirable; advisable;strange; urgent; preferable等。
It is a pity that … (should) do …此处和pity用法相似的形容词还有shame; wonder等。
5．在wish（。
就好了/但愿。
）; if only （。
就好了）; as if/though（好像/似乎）引导的从句中2)I wish I had taken that exam.3)I wish you could go with me.4)It looks as if it might rain.5)He talked about Mike as if he had known him before.6)If only I were a bird.7)If only I had taken his advice.6．在even if; what if; imagine引导的从句中从句谓语动词变化规则同if条件句的变化规则。
1)Even if he were wrong, you should not treat him like that.2)What if you came tomorrow instead of today?3)That was nice, but what if you had not finished it?4)Imagine that we were on a lonely island.注：区分even if和even thoughEven if he were thirty, he would behave like a kid.Even though he is thirty, he still behaves like a kid.Even if he would get all A record, he might fail to get the job.Even though he got all A record, he failed to get the job.7．在in case万一；lest以免；for feat that …恐怕引导的从句中在这些从句当中，谓语动词应该用should + do1)He took his raincoat in case it should rain.2)She put a blanket over the baby for feat that he should catch cold.3)He tiptoed lest he should wake up the baby.8．用had wanted | had hoped | had expected等引起的从句中表示原来希望做到而实际上未能做到的事情，其宾语从句谓语动词用would do。
1)I had hoped that I had called you last night.2)I had expected that I would go with you tomorrow.注：这类动词后面更多采用动词不定式作宾语，句意不变。
如：1)I had hoped to call you last night.2)I had expected to go with you tomorrow.9．由providing | provided (that); on condition that引导的从句中根据情况，可用虚拟语气，遵循if条件句谓语动词变换规则。
1)Provided they were given enough time, they would finish the work earlier.2)They would not be in trouble on condition that they had taken my advice.IV.情态动词+ have done此类结构是否属于虚拟语气的范畴，目前还没存在争议。
但不管怎样，这种结构经常单独或者和上面谈到的虚拟语气一起出现在试题当中。
