高考命题趋势
高考对虚拟语气的考查侧重于：在非真 实条件状语从句中的使用，含蓄条件 句中的用法，名词从句中的用法及一 些特殊句式中的用法。今后高考仍然 会重视对虚拟语气句型的考查，而且 试题语境会更灵活，考查角度更加多 样化。我们要在语境中准确理解运用 。

英语虚拟语气总结(一)
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。

大学英语四级考试语法系列讲座--虚拟语气1
大学英语四级考试系列讲座虚拟语气中国地质大学（武汉）外语学院许峰虚拟语气是英语动词的一种特殊形式，表示说话人主观上所说的话并不是事实，而是一种假设、愿望、建议、请求、命令、空想、猜测、必要性和可能性等。
虚拟语气是英语学习中的一个难点，也是大学英语测试中的重要的语法考点之一。
测试内容涉及到虚拟语气的方方面面——从在含非真实条件的主从句中的应用，到在各种从句(主语从句、宾语从句、表语从句、同位语从句、状语从句、定语从句)中的应用。
由于虚拟语气表达的是一种与事实相反的行为或状态，其谓语动词的变化不同于陈述语气，这也是学生感到困惑和容易出错的地方。
解此类试题时，关键是要迅速发现解题信息词，确定虚拟语气类型，然后按各类虚拟语气的特定表达方式，或根据结构或题句中的其他暗示，确定动词的形式。
第一节虚拟条件句一、虚拟语气在非真实条件句中的应用非真实条件句表示不大可能或不可能发生或实现的假设，句中的条件从句与结果主句皆须用虚拟语气。
其虚拟语气的时态可用下表表示：例1：If we left now, we should arrive in good time. 假如我们现在就走的话，我们就能及时到达。
(与现在事实相反)例2：If he had been here, he might have been able to help us.如果他在这里，他也许能帮助我们。
(与过去事实相反)例3：If you did that again, we wouldn't allow you to work with us.如果你再那么干，我们就不让你跟我们一起工作了。
(与将来事实相反)经典考点1：If the whole operation be fore hand, a great deal of time and money would have been lost.(CET-4，1999年6月)A)was not planned B)has not been plannedC)had not been planned D)were not planned巧解答案C。
虚拟语气(1)(2)
虚拟语气（一）－if引导的虚拟条件句虚拟语气(Subjunctive Mood)这一语法项目是各类英语考试中测试的重点之一。
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。
首先要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时间的事实相反。
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最基本的虚拟语气句型:1. 虚拟现在时表示与现在事实相反的假设，其if从句的谓语形式用动词的过去式(be一般用were)，主句用would/ should/ could/ might +动词原形。
If places were alike, there would be little need for geographers.2. 虚拟过去时是表示与过去事实相反的假设，if 从句的谓语形式用过去完成时的形式即had＋过去分词，主句用would / should / could / might + have +过去分词。
If he had known your address yesterday, he would have telephoned you.3. 虚拟将来时是表示对将来实现的可能性很小的或不确定的假设。
If从句的谓语形式用一般过去式或用were to/should +动词原形,主句用would /should/could /might+动词原形。
If he were to leave today, he would get there by Friday.谓语动词形式见下表:即时演练：1. I didn’t see your sister at the meeting.

英语虚拟语气完整归纳(1)
英语虚拟语气完整归纳(1)一、初中英语虚拟语气1． ---What if I have to go there and know nothing about it?--- If I______ you, I would try to find some information about it on the Internet.A．am B．was C．will be D．were【答案】D【解析】试题分析：句意：——倘若我必须去那儿而且对那里一无所知，该怎么办？——如果我是你，我会在网上查找一些有关那里的信息。
根据I would try to find可知主句用的是would+do,可知这是对现在事实的假设的虚拟语气，因此If引导的条件状语从句用一般过去时，根据虚拟语气的用法be动词在If引导虚拟语气中用were .故选 D。
考点：考查虚拟语气的用法。
2．If I _______ you, I _______ go there.A．is; will B．is; would C．were; would D．was; will【答案】C【解析】本题考查虚拟语气，if引导的与现在事实相反的虚拟语气。

(英语)中考英语总复习--虚拟语气含解析
（英语）中考英语总复习--虚拟语气含解析一、初中英语虚拟语气1．—I’m going to Larry’s party. But I don’t know what to wear.—If I ___ you, I _______ wear a dress.A．am; will B．were; willC．were; would D．am; would【答案】C【解析】试题分析：根据题干，本句的意思应是“如果我是你，我将穿一件裙子。
”“我”是不可能成为“你”，所以本句是一个虚拟语气。
对于虚拟语气，从句应该用过去式（be动词，不论是第几人称，都用were），主句用would do。
所以本题选C。
考点：本题考查虚拟语气。
点评：完成本题时注意区分虚拟语气和if引导的条件状语从句。
虚拟语气是不可能发生的，是一种假设情况；而if引导的条件状语从句，是有可能发生的。
如果不明白这两者的区别，就比较容易发错。

3、可能违背将来事实的假设 这里指的是将来不大可能发生的假设，或者虽有可能发生， 说话人主观上不希望发生的假设。这种假设相当于汉语中 常用的“万一”，“居然”，“竟然”等含义。例如： If he should fail, we would encourage him to try again. 万一他失败，我们就鼓励他再试一次。 If I were to do it, I would do it in a different way. 要是我来做这件事，我会是另外一种做法。 We would wipe them out if they should attract us. 如果他们胆敢进攻，我们就将他们消灭。 If it should rain tomorrow, what could we do? 万一明天下雨，我们能做些什么呢？ If the rocket should fail in a few seconds, it would certainly explode.如果火箭几秒钟内竟然向下坠落，那就一定会爆炸。
5、连接词 if 的省略 如果条件从句的谓语包含有had, should 或 were，有时 if 可以 省略。这时had，should 或 were 要移到主语前面，形成倒装。 （这种句型主要见于书面形式。） Had he not been ill, he might have come. 要不是生病，他是会来的。 Were I to do it, I would do it in a different way. 要是我来做这件事，我会是另外一种做法。 Should it rain tomorrow, what could we do. 万一明天下雨，我们能做些什么呢？ Were it not for his help, we couldn’t have got over the difficulties. 如果不是因为他的帮助，我们就克服不了这些困难。
虚拟语气
By Lynn
虚拟语气（subjunctive mood）是谓语动词的 一种形式，用来表示非真实的假设，或者用来表 示命令、建议或说话人的主观愿望。
一、非真实条件中的虚拟语气 非真实条件就是违背事实情况的假设，包括违背现在事 实的假设，违背过去事实的假设，以及将来不可能发生或 者虽然有可能发生但说话人主观上不希望发生的假设。最 后这一种假设简称为违背将来事实的假设。在这三种情况 下，条件从句和主句中的谓语动词采取下列虚拟形式。
4、介词短语表示的假设条件 有时不用 if 引导条件从句，而用介词短语表示违背事实的 假设条件，这时句中谓语动词仍用虚拟语气形式。例如： Without air, there would be no wind or clouds. 没有空气就不会有风，也不会有云。 In that case we could have done the work better. 如果是那样的话，我们本可能把工作做得更好些的。 But for the storm, we should have arrived earlier. 要是没有碰上暴雨，我们还会早一点到达。
二、其他从句中的虚拟语气 在表示建议、命令、要求以及表示“重要性”和“紧迫 性”等含义的主语从句、宾语从句、表语从句和同位语从句 中，谓语动词常用虚拟语气，由“动词原形”或“should+ 动词原形”构成。现分述如下： 1、主语从句 在下列结构的主语从句中，谓语动词用虚拟语气。 It is necessary that…(有必要…) It is imperative that…(必须… ,…是紧要的) It is important that…(重要的是…) It is essential that…(必须… ,…是必要的) It is advisable that…(最好… ,…是理想的) It is better that…(最好…)
2、违背过去事实的假设 If I had left a little earlier, I would have caught the train. 我要是早点动身就赶上火车了。 If she hadn’t taken your advice, she would have made a bad mistake. 她要不是听了你的劝告，就要犯大错了。 She would have come if she hadn’t been so busy. 要是不忙，她就来了。 I could have done it better if I had been more careful. 我要是细心一点，是可以做得更好的。 If he hadn’t been ill, he might have come. 要不是生病，他是会来的。
条件从句 违背现在 过去式
主句 should/ wo过去分词
should have/ would have+过去分词
违背将来
1）should+动词原形 should/ would +动词原 2）were+动词不定式 形
虚拟语气中主句中的第一人称用should，第二、第三人 称用would。但在美国英语中，第一人称用would。此外， 主句中也可用情态动词could或might代替should或would。 在条件从句中，如果动词是be，在违背现在事实时，各人 称都用were。（但在非正式文体中，特别是口语中，第一、 三人称用was的时候也不少。）在违背将来事实的条件从 句中，should+动词原形及were+不定式两种谓语动词形式 适用于所有人称。
1、违背现在事实的假设 If the earth had no gravity, the moon would fly to the sun. 假如地球没有引力，月球就要向太阳飞去。 If I were (was) you, I would reconsider their proposal. 我要是你，我就要重新考虑他们的建议。 If he were (was) you, everything would be all right. 要是他在这儿，一切问题都会解决。 What would you do if you were in his position? 要是你处在他的位置，你会怎么办？ If it weren’t (wasn’t) raining, we wouldn’t stay in door. 要是现在不下雨，我们就不会呆在屋里了。
