英语四级考试中的虚拟语气
英语四级考试中的虚拟语气英语四级考试中的虚拟语气虚拟语气在宾语从句中的用法是一个常见的考点，我们着重讲一下宾语从句常使用虚拟语气的几类特殊动词，以及这些动词的用法、构成虚拟语气的用法等。
下面是店铺为大家带来的英语四级考试中的虚拟语气，欢迎阅读。
一、何谓虚拟?在英语中，语气(mood)和时态，语态一样，都是谓语动词的一种形式。
表明说话的目的和意图，虚拟语气即表示说话人主观愿望或纯假设情况，动词需用特殊形式。
例如If I were a boy。
其中谓语动词用were，而不是am, shall, was, have等，是因为说话人为女士，而“我是男人”仅是其假设的语气，故用了一个在现实情况中绝不可能用到的were来表达这一虚拟的情况。
通过在I的后面加were这一词，能得知这是虚拟假设出来的情况。
常见的虚拟有两种：1. 表示非真实假设情况：If If I had left sooner, I could have caught the train。
如果早点出发，我就能赶上火车了。
(但我事实上已经错过了，对过去的假设虚拟)He talks so loud as if I were deaf。
他说话声太响，就像我聋了一样。
(但事实我没聋，对现在的假设虚拟)这种情况虚拟时，只需将谓语动词变本身的时态再变过去。
第一句话中的虚拟，本身为过去时，因此再变过去，即过去完成时。
left变为had left, could catch变为could have caught。
第二句话中，as if I am deaf，需要对现在假设，因此变为as if I were a deaf。
(不用I was deaf，避免与真实情况过去式混淆)类似表示非真实情况的`词还有wish希望， suppose假设， would rather宁愿， but for要不是等。
2. 表示建议、命令、要求等主观意愿：He suggested that a petition (should) be drawn up。
专四语法--虚拟语气
虚拟语气概念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。
在条件句中的应用条件句可分为两类，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。
真实条件句—主将从现egs.If he comes, he will bring his violin.典型例题The volleyball match will be put off if it ___.A.will rainB. rainsC. rainedD. 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。
非真实条件句1）时态：可以表示过去，现在和将来的情况。
它的基本特点是时态退后。
a.同现在事实相反的假设。
句型：条件从句主句一般过去时should( would) +动词原形If they were here, they would help you.b.表示与过去事实相反的假设。
句型：条件从句主句had done,should(would) have + doneIf she had worked harder, she would have succeeded.The rice would not have been burnt if you had been more careful.If my lawyer had been here last Saturday, he would have prevented me from going.If he had come yesterday, I should / would have told him about it.表示对将来的假想句型：条件从句主句一般过去时should+ 动词原形were+ 不定式would + 动词原形should+ 动词原形If you succeeded, everything would be all right.If you should succeed, everything would be all right.If you were to succeed, everything would be all right.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。

二,虚拟语气Ⅰ.条件状语从句中的虚拟语气①.基本形式 if 从句主句与现在相反过去时（were） would/could/should/might+ do与过去相反过去完成时would/could/should/might+havedone与将来相反 were to would/could/should/might+ doshould/could▲should也可以引导一个条件句,但所假设的事一般不会发生，且后面的主句（一般为祈使句）不能倒装。
②.倒装：如果条件句中的谓语动词含有were,should,had时，可以省略if，把三个词放在主语之前构成倒装，如果句子是否定句，not不跟着提前。
Eg. If he had come a little earlier, I might have met him.Had he come a little earlier, I might have met him.If he were to leave tomorrow, I would go with go with him.Were he to leave tomorrow, I would go with him.③.错综时间的虚拟条件状语Eg. If I had studied hard, I would be in a very comfortable office now.If you were older, I would have let you go yesterday.④.含蓄的虚拟条件状语从句：无if从句的出现，用其他形式表示出虚拟的意义，常见的词和词组：without, in the absence of,Otherwise, but for, butEg. Without your help, I couldn't have done it well.If you had not helped me, I couldn't have done it well.In the absence of water, plants couldn't grow well.If there were no water, plants couldn't grow well.He was held up in the traffic, otherwise, he wouldn't have been late If he hadn't been held up in the traffic, he couldn't have been late.But for the rain, our trip would have been pleasant.But for the rain, we would have a pleasant trip.If it hadn't rain, we would have a pleasant trip.I could have written the paper before, but I was still.II.其他状语从句中的定语从句ⅰ.让步状语从句在whethe r…or，though,no matter等引导的状语从句中，谓语经常用should/may+v.原，在这个句型中，可以将whether省略（or不可省），though，no matter省略，再省略should和may，而把动词be放在主语前面，构成倒装Eg. Everything around us, whether it may be/should be air, orwater, or stone, is matter.Everything around us, be it air or water, or stone, ismatter.Though he should/may be too weak to walk too much, I willadvise him to walk a little every day.Be he too weak to walk too much, I will advise him to walka little every day.ⅱ.在lest,in case,for fear that…引导的原因状语从句中，从句经常用should+v.原表示虚拟，其中in case可用陈述语气。

► 答案：A。通常情况下，虚拟条件从句如果使用的 是过去完成时，主句则使用“would + have done” 形式，表示对过去情况的假设。但当条件从句表示 的动作和主句表示的动作，发生的时间不一致时， 比如这句话，条件从句是对过去情况的假设，而主 句却是对被提问者现场当时感受的假设，主句动词 的形式就要根据表示的时间调整，采用“would + 动词原形”的形式。这种句子可以成为“错综时间 条件句”。有时情况跟此句正好相反，如：If you were in better health, we would have allowed you to join them in the work.

四级必用虚拟语气非常完整版
虚拟语气学习虚拟语气的三个必知英语一共有三种语气形式，所有的祈使句都是祈使语气，其他非祈使句的句子或者属于陈述语气，或者属于虚拟语气。
学习虚拟语气必须明确了解以下三点：1、英语的所谓“虚拟语气”，从用途上区别有三种：一种用来表达与实际情况相反的虚构假设，一种用来表达“祈使愿望”的口气，另一种满足特殊的句式需要。
虚拟语气：（1）用来表示说话人的主观愿望、请求、意图、建议、怀疑、假设等；（2）可能性很小或不可能成为客观事实的情况，常用于非真实条件句中 虚拟语气并不全是在表达虚构的情况，理解这一点非常重要。
2、虚拟语气从句式表现上有三种：表达与实际情况相反的虚构假设用were 式虚拟，表达“祈使愿望”的口气be 式虚拟，在特殊句式中的照句式要求而定。
3、学习虚拟语气，其目的不在于单纯解决语法问题，更不能停留在应试的层面上。
掌握虚拟语气的用法对英语的阅读理解非常重要，尤其是进入大学以后，这一点更为重要。
一、虚拟条件句：非真实条件句虚拟条件句因为有虚拟语气，所以条件句中的条件是不可能的，主句的结论也是想象的，非真实的，不可能的。
1. If it rains tomorrow, our trip will be put off.如果明天下雨，我们的旅行就延后（真实条件句）2. If he hadn ’t hurt his legs yesterday, he would go with us now.要是他昨天没有伤到腿，现在他就会跟我们一起去。
（虚拟）虚拟条件句的基本形式1. If it _______ not for the fact that he is ill, I _______ him to do this right now.要不是他现在病了，我就让他现在去办这件事。
Were would ask2. If we _______ adequate preparations, the conference _______ so successful.如果我们不是做了充分的准备，这次会议就不会这么成功。

专四常见虚拟总结
1.条件句的虚拟（if）比如：(1) 与过去事实相反If I had seen the film, I would have told you about it.(2) 与现在事实相反If he were free, he would help us.要是他有空的话，它会帮助我们的。
(3). 与将来事实相反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。
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。
注意省略if的倒装形式，比如：If I had studied hard, I would have passed the exam.Had I studied hard, I would have passed the exam.2. 一些表示请求、要求、命令或建议等意义的动词所接的宾语从句advise, ask, demand, desire, decide, insist, order, propose, request, sugge st其虚拟语气的结构为：(should) + 原形动词。
如：The teacher advised that we should make good use of every minute her 老师劝我们要好好地利用在这儿的每一分钟。
The Party asked that we should serve the people with our heart and soul 党要求我们要全心全意地为人民服务注意suggest和insist这两个词，当insist的意思为：坚决认为，坚持说；suggest的意思为：表明，暗含，暗示等时，宾语从句不用虚拟语气。
如：Tom insisted that he hadn’t stolen the watch.汤姆坚持说他没有偷那块手表。
四级虚拟语气详解
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。
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)；二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)。
一、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)主语+should,would,might,could＋动词原形与过去相反的假设If+主语+had +过去分词主语＋should, would, might,could＋have done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 +动词原形主语＋should, would，might,could＋动词原形eg: If I had time, I would attend the meeting.If he had hurried ,he could have caught the train.If I were to go abroad ,I would go to America.注意：使用虚拟条件句要注意的几点：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1、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、If you had studied hard before, you would be a college student now.如果你努力学习的话，你现在就会是大学生了．错综时间条件句例题：Had you listened to the doctor, you _____ all right now.A.areB. wereC. would beD. would have been 解析：这是个混合型的虚拟语气，前面是个省略加倒装句，还原后是 If you had listen to the doctor, you would be all right now. 如果你当初听医生的话，现在病都好了。
专四英语之虚拟语气用法和主谓一致知识讲解
一、虚拟语气用法讲解英语有三种语气，即陈述语气、祈使语气和虚拟语气二、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。
(但你没有坐出租车)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 had left sooner，I would have been on time. 要是我早点动身，我就准时到了。
(但我动身太迟了) 【I had left缩写I’d left；I would have been缩写为I’d have been】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a)If+主语+动词过去式;b)If+主语+were to+动词原形;c)If+主语+should+动词原形(注意不能是would)。
专四语法精讲-虚拟语气(内部资料)
if only和would that后用虚拟语气：谓语 动词用一般过去时表示现在没有实现的 的愿望，用过去完成时表示过去没有实 现的愿望，常译为“要是….就好了”。 例如：If only she had known where to find you. Would that I had seen her before she died. 在她死前我能见她一面就好了
Subjunctive Mood
虚拟条件句
条件从句 与现在事实相反 If I (we, you, he, she, it, they)+ 动词过去式（be动词的过去式 一律用were） 与过去事实相反 If I (we, you, he, she, it, they) + had +过去分词 If I (we, you, he, she, it, they) +would have +过去 分词 与将来事实相反 A式：一般过去式 B式：were +不定式 C式：should + 动词原形 Would (should) +动词原 形 结果主句 I (we, you, he, she, it, they) + would +动词原形
What would people say about him, whose wife should take bribes?
要是他的妻子接受贿赂的话，人们会怎样说他呢？ （定语从句）
含蓄条件句：有些句子中，没有任何表 示虚拟语气的词、短语或从句，但仍要 用虚拟语气。这是要么是省略了表示虚 拟语气的部分，要么隐含在上下文中， 称为含蓄条件句。 例如：I would do anything for you. (if I could)
专四——虚拟语气
在表示命令、建议或要求等动词后的宾语从句中要 求用虚拟语气，从句谓语形式 ：should+ 动词原 形。
It is +形容词/名词/过去分词/+that引导的主语从 句，从句谓语形式 ：should+ 动词原形。
Lest, in case, for fear that”以防，万一”引导目 的状语从句常用虚拟语气，从句谓语形式： should+ 动词原形。 Lest, for fear that从句中 should可省去， in case从句中should通常不省 去
4.在wh-ever, however ，no matter,等引导的让步状语从句中，从句虚拟语气的结构为： may+ 动词原形 （指现在或将来）或 may+完成式（指过去)，主句结构不限。
Should/would/could/might+ have+过去分词
Should/would/could/might+ 动词原形
省略if虚拟条件句的用法 在虚拟条件句中，如果从句中含有were,had,或should等词时，可将if省略，把were,had或should
等提到主语之前，引起倒装。
Eg: Had you not helped me, I should have failed.
