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。
虚拟语气四级讲解
Subjunctive Mood(虚拟语气)I 、In Conditional Sentences (用于条件句中)II 、In the That-Clauses (用于that 从句中)III 、In the Clauses and Constructions (用于从句和结构中)I. In Conditional Sentences (用于条件句中)或could ，第一人称还 可用should ，但美国英语都用would 。
如果条件句的谓语中含有were, had 或should 时，有时可省略if 而用把were, had 或 should 放到主语之前的倒装句。
现分别举例如下：1. 与现在事实相反 If I knew French, I would read the book in the original. If I were (Were I) in your position I would tell her the truth.2. 与过去事实相反 If you had (Had you) come a few minutes earlier, you would have caught the train.3. 与将来事实相反或表示推测 If he came tomorrow, I might have time to see him. If it were (Were it) to rain next Sunday, the match would be postponed . If we should (Should we) fail again, we wouldn't lose courage.虚拟语气（一）-- 虚拟语气在条件状语从句中的应用虚拟语气(Subjunctive Mood)这一语法项目几乎是四、六级必考的内容，也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。
英语四级语法 虚拟语气
虚拟语气一．一般虚拟条件句(1) 与现在事实相反——If I were you, I wouldn’t worry.——If I had the book at hand, I would read the passage to you.那么，虚拟语气现在时的句型为：从句：If + 主语＋动词过去式(be 变were) +…主句：主语＋would (should ,could ,might ) + 动词原形＋…(2) 与过去事实相反——If you had gone to last night’s games, you would have met him.——If the policeman had arrived earlier, he would have seen the accident.那么，虚拟语气过去时的结构是：从句：If＋主语＋过去完成时…主句：主语＋should (或would,could,might) + 现在完成时…(3) 与将来事实相反——If he should come tomorrow, I would give him the dictionary he needs.——If Mr. Li were to do the experiment tomorrow, he might read the instructions carefully.那么虚拟语气将来时的句型是：从句：If+主语＋should (或were to )+动词原形＋…主句：同虚拟语气现在时的主句结构。
练习：1.I f this report were more accurate, it __________ an invaluable document.A.wereB.had beenC.will beD.would be(D)2.I _______ in trouble if the police had stopped me.A.wereB.would have beenC.would beD.had been(B)3.W hat would you do if war _________ out.A.breaksB.could breakC.had broken outD. were to break(D)二、在if引导的虚拟条件句中，若有were, had, should，可省去if,将were, had, should提到主语前，形成倒装。

四级语法真题解析虚拟语气解析
四级语法真题解析虚拟语气解析四级语法真题解析——虚拟语气解析在四级英语考试中，语法是一个重要的考点，而虚拟语气作为其中的一部分，往往会引起考生的困扰。
本篇文章将从真题解析的角度，重点讲解四级考试中常见的虚拟语气用法和解题技巧。
1. 引导条件状语从句的虚拟语气在各类真题中，虚拟语气通常用于条件句中。
在条件句中，如果假设的条件与事实相反或者不可能实现，就要使用虚拟语气来表达。
例如，2019年6月份四级阅读真题中的一道题目是："If you had learned to play a musical instrument as a child, you _____ playing one now."A. might have enjoyedB. might enjoyC. must have enjoyedD. would enjoy这道题目考察的就是过去的虚拟语气。
根据题意可知，主句中使用的是过去完成时态，在此基础上，我们需要使用与过去相反的虚拟语气形式。
因此，在条件从句中使用过去完成时态的虚拟语气，答案选项为A，即"If you had learned to play a musical instrument as a child, you might have enjoyed playing one now."2. 引导宾语从句的虚拟语气在四级考试中，虚拟语气有时也会用于宾语从句中。
特别是在一些形容情感、命令、建议等动词后面的宾语从句中，常见虚拟语气的运用。
例如，2019年12月份四级阅读真题中的一道题目是："He recommended that the patient _____."A. sees a specialistB. will see a specialistC. saw a specialistD. see a specialist根据题目可知，主句中使用了虚拟语气动词"recommended"，因此在宾语从句中需要使用虚拟语气形式。

该语法主要用于if条件状语从句。
一、if引导的条件状语从句的分类及虚拟条件句的判断1、可以把条件句分为两类：1).真实条件句(Sentences of Real Condition)：凡是假设的情况发生性可能很大，就是真实条件句。
例如：⑴、If I have time , I will help you with this work.如果我有时间会帮助你做此工作的。
⑵、As long as I say anything wrong, you must point it out.只要我说了什么错话，你一定要指出来。
⑶、If time permits, we'll go fishing together.(如果有时间的话，我们就一起去钓鱼。
)2).虚拟条件句(Sentences of Unreal Condition)：当假设是不大可能实现时，就是虚拟条件句。
例如：⑴、If I were you , I would have attended the meeting. 如果我是你的话，就去参加会议了。
⑵、If he had come here yesterday, he would have seen his old friend.假如他昨天来这儿的话，就会看见他的老朋友。
⑴、If it had rained yesterday, we would have stayed at home.(如果昨天下雨的话，我们就会留在家里。
)2、.if条件状语从句中虚拟语气的判断判断是真实条件句还是非真实条件句。
只有在非真实条件句中才使用虚拟语气。
通过句子意思，看假设的条件是否能够实现，能够实现是真实条件句，不能使用虚拟语气;假设的条件不能实现则是非真实条件句，要用虚拟语气。
判断这个假设是与哪个事实相反。
通常有三种情况：①与过去事实相反。
②与现在事实相反。
③与将来事实可能相反。
3、“后退一步法”后退一步法是指在准确地判断了该句与哪一事实相反后，按虚拟语气的后退一步法处理从句谓语动词的时态。
即：在非真实条件状语从句中，谓语动词按正常情况“后退一步”。
也就是：①与过去事实相反，在从句中用过去完成时形式表示。
②与现在事实相反，在从句中用过去一般时形式表示。
③与将来事实可能相反，在从句中用过去将来时形式表示。
主句中则用情态动词would, should, could 等加一个与从句一致的动词形式。
例：⑴、If I had come her yesterday, I would have seen him.⑵、If I were a teacher, I would be strict with my students.⑶、If it should snow tomorrow, they couldn't go out.4、注意事项①if条件句中如有were, should, had，可以省去if，并使用倒装语序。
②在现代英语中if条件状与从句中的谓语动词如果是be其过去形式一般用were。
二、虚拟语气在if 引导的条件句中的用法：(一)、表示与现在事实相反的情况。
其句子结构为：从句：if + 主语+ 动词的过去式(be 用were) + ……主句：主语+ would (should, could , might) + 动词原形+ ……例：1.If I were you, I would go with him.2.If the weather were fine, I would go there.如果天气好，我去那儿。
(事实天气不好)3.If I were you, I would read it again.如果我是你的话，我再读一遍。

(事实上时间不允许)5.If it weren’t snowing, we wouldn’t stay in the house.要是现在不下雪的话，我们就不会待在屋里。
(事实上现在下雪)6.What would I do if I were in your place?要是我处于你地位我会怎么办?(事实上我不在你的位置上)7.If he hurried, he could catch the first bus.他要是快点能够赶上头班公共汽车。

)(从句用过去式动词had，主句用动词原形study)13. If she knew English, she would not ask me for help.(如果她懂英文，她就不必要我帮了。
)(从句用过去式动词knew, 主句用动词原形ask)注意：如果动作在进行中，主句要用："主语+ would be + 进行式动词+ ……"14. If they were here, he would be speaking to them now.(从句用过去式动词were, 主句用would be speaking)(二)、表示与过去事实相反的虚拟条件句。
其句子结构为：从句：If + 主语+ had +过去完成式动词+ ……主句：主语+ would (should, could, might) + have +过去完成式动词+……例如:⑴、If you had taken my advice, you would not have made such a mistake.如果你听了我的劝告,就不会犯这样的错误。
(事实上你没有听我的劝告)⑵、I shouldn’t have been able to write such good novels if I hadn’t lived among the peasants for five years.如果我不是和农民生活了五年，就不可能写出这样好的小说。
(事实上我和农民生活了五年)⑶、If you hadn’t invited me, I shouldn’t have come to the party.如果你不邀请我，我就不会来参加你的舞会。

(事实上我不是)⑻、If you had studied harder last term, you could have passed exam.(从句动词用had studied, 主句动词用have passed)如果你在上个学期用功一些，你就会在考试中过关了。
⑼、If you had taken my advice, you wouldn't have failed in the exam.(从句动词用had taken, 主句动词用have failed)如果你当时听从我的劝告的话，你就不会在考试中失败了。
⑽、If you had got up earlier, you could have caught the train.(从句动词用had got up, 主句动词用have caught)如果你起身得早一点，你就会赶得上火车了。
⑾、If it had snowed, I would have skied in the park.(从句动词用had snowed, 主句动词用have skied)如果下雪的话，我就可在公园里滑雪了。
注意：如果动作在进行中，主句要用："主语+ would + have + 完成进行式动词+……⑿、If they had been here, he would have been speaking to them.(从句动词用had been, 主句动词用have been speaking)(三)、表示与将来事实相反的虚拟条件句(对将来的事实实现的可能性不大)。
其句子结构为：从句：If + 主语+ should (或were) + 动词原形+……主句：主语+ would (could, should, might) + 动词原形+……例如：⑴、If I were to work at this problem, I would do it in another way.要是我来解这道难题，我会用另外一种方法的。
⑵、If you were to do such a thing again, you would be punished. 如果你再做这样的事情，就会受到惩罚。
