虚拟语气知识点总结
语气第一节语气英语的动词一般可带有三种不同的语气：陈述语气，祈使语气和虚拟语气。不同的语气用动词的不同形式（有的还借助句法形式）来表示。第二节虚拟语气的概念虚拟语气是一种特殊的动词形式，一是用来表示说话人所说的话不是一个事实，而是一种假设、猜测、怀疑等(在条件从句中或让步状语从句中)；一是表示说话人的愿望、要求、命令、建议等 (在宾语从句、表语从句、同位语从句)。它能实现下列交际功能：a、用来表达一个假设或纯粹的意愿（这种假设或意愿在多数情况下是与事实相反或不太可能实现的。
b、经常用来缓和语气，使之更加委婉、礼貌、得体，使句子带有推测性和尝试性。
c、表示烦恼、不耐烦等情绪。
d、表示适度的责备或批评。
e、表示美好的祝愿或祝福。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。第三节虚拟语气在条件句中
虚拟条件句
主句与现在事实相反的假设If+主语+动词的过去式（动词be 用were)The platform would collapse if all of you stood on it、假如你们都站在上面，这个平台就会塌下来的。主语
+should,would,might,could＋动词原形如果鲁迅还活着，看到新中国的伟大成就他会多么高兴啊！与过去相反的假设If+主语+had +过去分词If the doctor had been available,the child would have been saved、如果有医生在，这个小孩就会得救了。主语
＋should, would, might, could＋have done如果飓风发生在白天，死亡的人数会更多。与将来相反的假设
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I could see the surface of the moon with my own eyes if I were to go to the moon some day、如果有一天我登上了月球，就能亲眼目睹月球的表面是什么样子了。主语＋should, would might, could＋动词原形
如果明天是星期天，我就去看望我奶奶。NOTE：使用虚拟条件句
要注意的几点：１、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，被称为：错综时间条件句“，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、如果你听我的建议，你现在就会痊愈了、２、在条件句中，可省略 if，把were ,had, should 提到句首，变为倒装句式、（后面详细讲解）If you had come earlier, you would have met him、Had you come earlier, you would have met him、
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。
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。
She would have gone to the party if she had been invited、
要是当初她被邀请的话，她就会去参加这次聚会了。
（事实是：当时没有人邀请她，因此，她没有来参加聚会。表示后悔。）
If she hadnt called me, I would have overslept this morning、
今天早上，她要是不叫我的话，我就会睡过头了。
（事实是：她今天早上叫我了，我没有睡过头。表示感激。）
3、与将来事实可能相反的虚拟条件句，条件从句的谓语用动词的过去式(be的过去式用were)； should＋动词原形；were to＋动词原形，主句用should （would, might， could）+动词原形。
If I were to be twenty years old next year, I would take the course of French、
明年我要是二岁，我就会学法语。
（事实是：我现在已经老了，明年我学不了法语了。）
If it should fail, I would try again、要是失败了，我会再试一次。
（事实是：有可能失败，可我会再试。表示未知。）虚拟过去式有时并不表示“不大可能实现的假设”，而是表示一种希望或不希望发生的动作。
If we caught the early train, we’d get there by lunch time、
假如我们赶上早班火车，到午饭时间我们就会到达那里了。(表希望)
If we missed the train, we should have to wait an hour at the station、
假如我们赶不上这班火车，我们就得在车站等一小时。（表不希望）
4、混合型的条件句
当条件从句与主句所表的时间不一致时，虚拟语气的形式应作相应的调整。主句和从句的谓语动词并不相互呼应，这种条件句叫混合条件句。较多见的混合型条件句是从句用过去完成时（指过去行为），而主句用一般时（指目前状态）。H e would pass the test if he had taken my advice、如果他听了我的劝告，他现在会通过考试。If I had spoken to him yesterday, I should know what to do now、
假如昨天我对他说了，现在我就知道该怎么办了。You would be much better now if you had taken my advice、假如你接受了我的意见，你现在就会好得多。
如条件从句用if I were、、、，主句则可用表任何时间的虚拟形式。
If I were not busy, I would have come、
假如我不忙，我就会去了。(were表过去)
If I were you, I would go、
假如我是你，我会去的。(were表现在)第四节虚拟语气在名词从句中的运用
一、虚拟语气在主语从句中
A、在句型“It is important (necessary, strange, natural)
that 、、、、” 中，表示某事重要、奇怪、自然、必要等；that 后面的从句中的谓语动词用：
should + 动词原形（should可以省略）It’s important that we should take good care of the patient、重要的是我们要照顾好病人。I t is necessary that he（should）be sent there at once、
Its strange that he should say so、
I was glad that he should go、
It is important that we should speak politely、
It is a pity that she should fare so badly、
Its right that you should think that way、这类的形容词还有advisable（可取的），appropriate（适当的），
compulsary（必须的），crucial（关键的），desirable（理想的），essential（必要的），imperative（迫切的），important(重要的)，possible（可能的），preferable（更好的），probable（可能的），strange（奇怪的），urgent（急迫的），vital（极为重要的）等。
B、在It is
demanded/suggested/ordered/required/recommended/requested /required/、that-clause句型中从句用(should )+动词原型，表示愿望，建议，请求等主观意愿等。I t is demanded that we should work out a plan、 It is requested that Professor Liu（should）give us a lecture、
It is desired that we（should）get everything ready by tonight、
I’m ashamed you should have done such a thing、
It has been suggested that the meeting（should）be put off、有人建议推迟会议。
It is settled that you leave us, then?
C、在 It is a pity/a shame/ no
wonderproposal/recommendation/suggestion/surprise/advice that…、、句型中从句也常用(should )+动词原型,表示建议，命令，请求，道歉，怀疑，惊奇等。I t’s a pity that you (should)
miss a good chance、注意：这种句型中的主语从句也可用陈述语气，如：It was important that he made an explicit statement on this score last week、他上个星期对于这一方面做了明确的说明，这是很重要的。
二、用于宾语从句宾语从句在表示提议、要求、命令、意志等动词后，其谓语用should+动词原形或只用动词原形的虚拟语气，作为suggest，request，demand，urge，propose，prefer，advise，insist，require，order，command，maintain，ask，object, arrange, desire等动词的宾语。注意：suggest 当表示“暗示、表明“讲时，insist 表示”坚持认为“之意时，应用陈述语气。The teacher suggested that we should clean the blackboard after class、老师建议我们课后把黑板擦了。The smile on his face suggested that he was satisfied with our work、他脸上的表情表明他对我们的工作很满意、He insisted that all of us be there on time by any means、他坚持要求我们大家想尽办法按时去那里。The man insisted that he had never stolen the money、那个人坚持说他没有偷钱、The doctor suggested that he not go there、医生建议他不要去那里。He suggested that we should leave early、他建议我们早点动身。The judge ordered that the prisoner should be remanded、法官命令被告还押。w ish的宾语的从句，表示愿望，常省去连词that。
☆ 从句的谓语动词可用过去式，表示现在的愿望（与现在事实相反），虽实现的可能性不大，但仍有实现的可能。I wish it were true、我但愿这是真的。I wish I were a bird、（were 与wish 发生在同一时间平面上）
☆ 从句的谓语动词还可用“could（would，might）+动词原形”用来表示将来的愿望 I wish you would stay a little longer、我希望你再待一会儿。I wish that the rain could stop soon、
☆ 表示无能为力的过去愿望（与过去事实相反），可用“had +过去分词”或“could（would，might）+have+过去分词” I wish you had called yesterday、我希望你昨天来过电话。I wish you had come to our Christmas party、We wish you had come to our New Year’s party、我们真希望你来参加了我们的新年联欢会。would rather，would sooner, would as soon,would prefer + 从句也常用虚拟语气，表示宁愿、但愿之意。这种虚拟语气表示的不是与事实相反的假设，而是一种尚未实现的愿望
☆ 表示与现在和将来含义事实相反的虚拟语气要用动词的过去式：
I would rather you came tomorrow、我宁愿你明天来。
I’d sooner she left the heavy end of the work to some one else、我宁愿她把重活留给别人。I would rather you
left today、我宁愿你今天走。I would sooner my daughter attended a public school、但愿我的女儿能上公立学校。I would prefer he didn’t stay here too long、我倒希望他不要在这儿待得太久。☆ 用过去完成式(had + 过去分词)表示过去事实相反的含义：
I would rather I hadn’t seen that film yesterday、
我宁愿昨天没有看那场电影。有些动词，如think, expect, believe,其否定式的宾语从句亦可用should+动词原形。如：
I never thought he should refuse、我万没有想到他会拒绝。She did not expect that you should come、她没有预料你会来。
三、用于表语从句和同位语从句在suggestion / proposal / order / plan / advice / idea / request /desire/ recommendation/resolution 等名词后的表语和同位语从句中要
用“should＋动词原形”should可以省略、 My advice is
that you should practice speaking English as often as possible、我的建议是你要尽可能经常地练习说英语。The suggestion that the mayor should present the prizes was accepted by everyone、每个人都接受由市长颁发奖金这一建
议。名词suggestion，proposal，order，advice，demand等作
主语，其后的表语从句中的谓语动词一般使用虚拟语气，用
should +动词原形或省略should。My suggestion is that we (should)
send a few soldiers to help them、
我的建议是我们应派几个战士去增援他们。My advice is that you (should)
treat her well、
我的忠告是你应该善待她。He makes the demand that she (should)
leave the place at once、
他提出一个要求，要求她立刻离开这个地方。My suggestion is that we should tell him、我的建议是我们应该告诉他。Our only request is that this should be settled as soon as possible、我们唯一的请求就是尽快解决这个问题。
注意：虚拟语气也可以用于同位语从句。如：There was a suggestion that Brown should be dropped from the team、有一项建议是布朗应该离队。四、虚拟语气在定语从句中的应用
常用在It is time (that)…句型中，定语从句常用虚拟过去式
It is (high / about )
time that…从句中的谓语动词用过去式或should＋动词原形，should不能省略、It’s high time we went to the laboratory、该是我们去实验室的时候了。
It is time the children went to bed、
孩子们早该上床睡觉了。（表示催促）
Its high time that he began to think how to deal with money、
他早该开始考虑如何与钱打交道。
It is time we left、我们该走了。
It is time we went to bed、我们该去睡觉了。五、虚拟式动词原形亦常用在独立句中，表愿望
Long live the Communist Party of China！中国共产党万岁！
God bless you! 上帝保佑你。
God damn it! 该死的！
The devil take you! 见鬼去吧！So be it then、就那样吧。第五节虚拟语气在其他从句中If only 引导的感叹句（要是、、、该有多好啊；但愿)；1 表示与现在或未来事实相反的愿望。用过去时或would/could+动词原形表示；If only you listened to us!要是你听我们的话该多好啊！2 与过去事实相反的愿望，用过去完成时。例如：If only I had listened to the doctor’s advice! 我要是听了医生的话就好了。a s if ( as though)
看起来even if ( even though)即使常用虚拟形式，其构成形式与wish后宾语从句里的虚拟语气的构成形式相同，表示与现在事实相反（从句意上判断），用过去式；与过去事实相反用
过去完成式 (had done)，would/could +动词原形。例如：The football fans of act as if they were crazy、那些足球迷们经常就像疯了似的。（act与were发生在同一时间平面上）He often talks about London as though he had been there、(had been there发生在talkes之前)
他常常谈起伦敦，就好像他去过那里似的。She often talks and talks as if she would never stop、 (would never stop 后于talks and talks 发生)她常常讲起来没完没了。
虚拟语气在in order that,so that,in case，lest，for fear that引导的目的状语从句中的应用，从句中的谓语动词用"may(might)＋动词原形"或"should＋动词原形"。在以lest引导的从句中，谓语动词用"should＋动词原形"。例如：He took his raincoat with him in case it should rain、他拿上了雨衣以防下雨。He was punished lest he should make the same mistake again、他被处以惩罚以免他再犯。He put his coat over the child for fear that he (should)
catch cold、他把外套给孩子穿上以防孩子感冒。
虚拟时态与谓语动词时态的关系：从句中的虚拟时态往往不受全句谓语时态的影响。
1)
用于主语从句。试比较：
It is important that he should know about this、他必须知道此事。
It was important that he should know about this、他必须知道此事。
2)
用于宾语从句。试比较：
I suggest that we should go tomorrow、我建议我们明天走。
I suggested that we should go the next day、我建议我们第二天走。
She said, “If I were a boy I would join the army、”她说，“我如是男孩，就参军。”
She said that if she were a boy, she would join the army、她说她如是男孩就参军。
但强调现在时刻的虚拟式在间接引语中需要遵守时态一致的原则。试比较：
“If I knew how it worked, I could tell you what to do,” he said、
“假如我知道它是如何运行的话，我就会告诉你该怎么办，”他说道。
He said that if he had known how it worked he could have told me what to do、
他说假如他知道它是如何运行的话，他就会告诉我该怎么办。
“If I knew the answer to all your questions Id be a genius,” he said、
“我如知道你所有问题的答案，我就是天才了。”他说道。
He said that if he knew the answer to all my questions, he’d be a genius、
他说他如知道我所有问题的答案，他就是天才了。
但如果全句谓语是虚拟语气，其后从句的时态则多受其影响，现在时态应随之而变为过去时态。如：I would think he was wrong、我看他是错了。(须用was,试比较：I think he is wrong)It would seem that she was right、她似乎是对的。(须用was,试比较：It seems that she is right)第六节、连词if的省略
如果虚拟条件句的谓语部分有were，had和should时，可省略if，把were，had和should放到从句主语前面去，多见于书面语。
Had you not helped me， I should have failed、要是没有你的帮助，我就失败了。
Were you in my position, you would do the same、假如你处在我的地位，你也会这样干的。
Should they attack us, we’ll wipe them o ut completely、假如他们进攻我们，我们就把他们彻底消灭干净。第七节、含蓄条件句
虚拟条件句中的条件从句有时不表出来，只暗含在上下文中，这种句子叫做含蓄条件句。含蓄条件句大体有三种情况。1) 条件暗含在短语中。
But for your help we couldn’t have succeeded in the experiment、
如果没有你的帮助，我们的实验是不会成功的。(暗含在分词短词but for your help)
What would I have done without you? 如没有你，我会怎么办呢？(条件暗含在介词短语without you 中)
It would be easier to do it this way、这样做会比较容易。
(条件暗含在不定式短语 to do it this way中)
This same thing, happening in wartime, amount to disaster、
同样的事，如发生在战时，就会酿成大祸。(条件暗含在分词短语happening in wartime 中)
He must have the strength of a hippopotamus, or he never could have vanquished that great beast、他一定是力大如河马，否则他绝不会击败那只庞大的野兽。(暗含条件是连词
or) Alone, he would have been terrified、如是单独一人，
他是会感到害怕的。(暗含条件是alone)2)
条件暗含在上下文中。
You might stay here forever、你可以永远待在这儿。(可
能暗含if you wanted to)
We would have succeeded、我们本来是会成功的。(可能暗
含if we had kept trying)
Your reputation would be ruined、你的名誉会败坏的。(可能暗含 if you should accept it)3)
在不少情况下，虚拟式已变成习惯说法，很难找出其暗含的
条件。
You wouldn’t know、你不会知道。I would like to come、我愿意来。
第八节、不用if引导的条件从句
虚拟条件句中的条件从句除用if引外，还可用when, unless, lest, suppose, as if, for fear, in case, on condition 等
词语来引导。
The peasants prepared to feed the city when it should be freed、
农民已准备在这座城市解放后供给粮食。
Lest you should not have heard all, I shall begin at the beginning、
我怕你没有听全，所以我再从头开始讲一遍。
Un less I were well, I wouldn’t be at school、除非我好了，否则我不会上学。
Suppose you were given a chance to study in America , would you accept?
假如给你一个到美国学习的机会，你会接受吗？（suppose 或 supposing =what if）
Supposing it were so？（=Supposing it were so，what would happen？）
要是这样的话，会怎么样呢？
He can use the bicycle on condition that he should return it tomorrow、
如果明天能还回来，他就可以借用这辆自行车。
In case I forget , please remind me of my promise 如果我忘了，请提醒我的诺言。
Susan is walking slowly ,as if she were tired、苏珊走得很慢，就像是累了似的。
与if一样，上述词语所引导的条件从句亦可用直陈语气，表可能实现或发生的事。虚拟语气专项练习

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）
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 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
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：
虚拟语气 在英语文法中有三种语气，即直述式语气(In dicative 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，女口：How beautiful she is!则是直述式语气，而Hurry up! Do n't 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 虚拟语气其他习惯用法简表
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。
专四语法（虚拟语气） 虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。 条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。 eg. If he comes, he will bring his violin. 典型例题 The volleyball match will be put off if it ___. A.will rain B. rains C. rained D. is rained 答案B。真实条件句主句为将来时，从句用一般现在时。 注意： 1）在真实条件句中，主句不能用be going to表示将来，该用shall, will. (错) If you leave now, you are never going to regret it. (对) If you leave now, you will never regret it. 2）表示真理时，主句谓语动词便不用shall (will) +动词原形，而直接用一般现在时的动词形式。 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 ?If I had time, I would do it again. ?If I had known of your arrival, I should have met you at the station. ?If she had further considered the problem, she might have come to the correct conclusion. 真题举例：
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：

英语虚拟语气总结（一） 一、概说 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：He is honest. 他很诚实。(陈述语气) Don’t be late next time. 下次别迟到。(祈使语气) If I were you I wouldn’t go. 我要是你，我就不会去。(虚拟语气) I wish I had a lot of money. 要是我有很多钱就好了。(虚拟语气) 二、带虚拟条件的虚拟语气 1.真实条件句和非真实条件句 条件句有真实条件句和非真实(虚拟)条件句两种。真实条件句所表示的假设是有可能发生的，而非真实条件句则通常表示一种假想，与事实相反或不大可能会发生：If I have time, I will go with them. 假若我有时间，我就同他们去。(陈述语气) If I were you, I would go with them. 假若我是你，我就同他们去。(虚拟语气) 2.虚拟条件句的三种基本类型 (1)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)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)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) 注：① 主句谓语中的should主要用于第一人称后。would, might, could的大致区别是：would表示结果，might表示可能性，could表示能力、允许或可能性。比较：If you tried again you would succeed. 要是你再试一试，你就会成功的。(would 表结果) If you tried again you might succeed. 要是你再试一试，你可能会成功的。(might
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

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)
虚拟条件句 Q: What’s the difference between the two sentences If I am free, I will visit you. (______条件句) If I were a bird, I would fly into the sky. (______条件句) a. 真实条件句表示条件是真的或有可能实现的, 采用陈述语气。 真实条件句用于陈述语气,假设的情况可能发生,其中if是“如果”的意思 条件从句主句 一般现在时 will \shall+动词原形 . What will you do if it rains tomorrow I will stay at home if it rains tomorrow. The football match _______ put off if it______(rain). b. 虚拟条件句表示条件是无法实现或几乎无法实现的, 采用虚拟语气。 I. 虚拟语气 虚拟语气就是表示与真实情况相反的一种假设、愿望或推测。 Subjunctive mood is the verb form used to express a wish; a suggestion; a command or a condition that is contrary to a fact. If I ________(be ) the girl, I________________(want )a big hug. If I ______(meet ) Obama, I________________ (shake) hands with him. 1.同现在事实相反的假设 条件从句主句 过去式(were) should/would/mould/might/+ do If I had a lot of money, I would donate some to the people in need. 2.与过去事实相反的假设 条件从句主句 had done would/should/could/might + have done . If he had driven more carefully, he would not have had the car accident in May,
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
虚拟语气用法总结
虚拟语气用法总结 朱世梅 新时代大学英语中针对虚拟语气的练习题较多,而学生们往往把握不好虚拟语气的正确使用,现将其用法总结如下: 一.虚拟语气在英语里主要用来表达： a. 非真实的情景，不可能发生的事，即某种与事实相反或难以实现的情况，或说话人主观愿望。 b. 与客观事实相反地情景，即强制性虚拟语气，表示建议、命令、劝告这一类的意思上，表示强烈的要求做到、必须做到这样的含义。 c. 虚拟语气的表达形式是通过动词的变化形式表达的，其特点是主从句时态的不一致，而且一般有明显得标志。 二.虚拟语气的考点为： 1.If 句型 (共有三种句型) 非真实条件句: a.与现在的事实相反：从句用一般过去时，主句的谓语用would (could, might) ＋动词原形 If I were Bill Gates, I would not work so hard every day. b.与过去的事实相反：从句用过去完成时，主句的谓语用would (could, might) ＋现在完成时 If I had gone to America when I graduated from middle school, I would have got my PhD degree. c.与将来的事实相反：从句用should (were to，did) + 动词原形，主句的谓语用would (could, might) ＋动词原形 If it should/were to snow tomorrow, I would go skiing.
注意：虚拟条件句的倒装虚拟条件句的从句部分如果含有were, should, 或had, 可将if省略，再把were, should或had 移到从句句首，实行倒装。 Eg: Should it rain, the crops would be saved. =Were it to rain, the crops would be saved. Eg:_____ to do the work, I should do it some other day. A. If were I B. I were C. Were I D. Was I 答案C. 在虚拟条件状语中如果有were, should, had这三个词，通常将if省略，主语提前, 变成 were, should, had +主语的形式。但在虚拟条件状语从句中，省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说 Were I not to do., 而不能说 Weren't I to do. d.混合条件句主句与从句的动作发生在不同的时间，这时主，从句谓语动词的虚拟语气形式因时间不同而不同，这叫做混合条件句。例如：条件句动作发生在过去，主句的动作发生在现在)谓语动词要根据表示的时间进行调整。 Eg: If it had rained last night (过去), it would be very cold today (现在). 2.Wish 句型表达“但愿…，要是…多好”的语气表示与事实相反的情况，或表示将来不太可能实现的愿望。其宾语从句的动词形式为： He wished he hadn't said that. 他希望他没讲那样的话。 I wish it would rain tomorrow. 我希望明天下雨就好了。 Wish to do表达法: Wish sb / sth to do I wish to see the manager. = I want to see the manager. I wish the manager to be informed at once. (= I want the manager to be informed at once.) 3.在强制性语气的宾语从句中的运用即表示建议、命令、劝告、决心等主观色彩的动词 + that + (should) + 动词原形，其中should 经常被省略。这类动词包括： suggest, propose, recommend, demand, order, command, desire, require, insist,
