虚拟语气表示不符合事实的假设、猜测、愿望和建议。虚拟语气是通过句中的谓语动词的特殊形式来体现的。虚拟语气的用法多种多样, 下面主要论述一下if状语从句和would rather句型中的虚拟语气。
一、虚拟语气在含if状语从句的复合句中的使用
1. 与现在事实相反的假设, 从句谓语动词的形式用动词的过去时 (be动词用were) , 主句谓语动词的形式为“would/could/might/should+动词原形”。例如:
(1) If she were not busy, she would attend the meeting this afternoon.
(2) If I were you, I would consult it with my parents.
2. 与过去事实相反的假设, 从句谓语动词用“had+过去分词”, 主句谓语动词的形式为“would could/might/should+have+过去分词”。例如:
He would have already recovered from hisillness if he had seen the doctor in good time.
3. 与将来事实可能相反的假设, 从句的谓语动词的形式有三种:
(1) 动词的过去时 (be动词用were) ; (2) should+动词原形; (3) were to+动词原形。主句的谓语动词的形式为“should/would/could might+动词原形”。例如:
(1) If it rained tomorrow, our picnic would be put off.
(2) If he were to recover from cancer, he should be the luckiest person in the world.
4. 省掉if条件状语从句的用法。在书面语中, 如果条件状语从句的谓语中有were, had或should, 可将if省略, 而把were, had或should置于主语之前。例如:
(1) Were I you, I would seize the chance.
(2) Had he followed your advice, he would not have made such a big mistake.
5. 混合型虚拟条件句。有时条件状语从句的动作和主句的动作发生的时间不一致, 这时动词的形式应根据它要表示的具体时间来决定。例如:
(1) If she hadn’t trained so hard, she wouldn’t be able to run so fast.
(2) If he had worked hard at school, he would be a college student now.
6. 用介词短语代替条件状语从句的用法。常用的介词有with, without, but for等。例如:
(1) But for your help, I wouldn’t have passed the examination.=If it hadn’t been for your help, Iwouldn’t have passed the examination.
(2) They couldn’t have completed the building task without modern equipment.=They couldn’have completed the building task, if there had not been modern equipment.
二、would rather句型中的虚拟语气
如果说话者的愿望与现在的事实相违背, 从句的谓语动词用过去时;如果说话者的愿望与过去的事实相违背, 从句的谓语动词用过去完成时。例如:
(1) I would rather you knew nothing about it. (事实上已经知道了)
(2) I would rather they had never given us support. (事实上他们已经给过建议了)
下面我们分以下五种情况来讲述虚拟语气的用法。
一、虚拟语气在if 引导的条件从句中的用法。（主句与从句中的谓语动词的形式如下表）
e.g. 1. If I were you, I would go at once.
假如我是你的话，我会马上走。(表示与现在事实相反)
2. If you had come a few minutes earlier, you would have met him.
要是你早来几分钟的话，你就能见到他了。(表示与过去事实相反)
3. If it should rain tomorrow, the meeting would be put off.
如果明天下雨的话，会议将被推迟。（表示与将来事实相反）
注意：（一）当if条件从句中谓语有were, should, had 时，可省略if, 把were, should, had提到句首，采用倒装。e.g.
1. If I were you, I would agree to the plan.
Were I you, I would agree to the plan.
如果我是你的话，我就会同意这项计划。
2. If I had known more about giving first aid, I would have helped them.
Had I known more about giving first aid, I would have helped them. 如果我懂得更多如何给予急救的知识的话，我就能够帮助他们了。
3. If it should rain, the crops would be saved.
Should it rain, the crops would be saved.
如果下雨的话，庄稼就能获救了。
(二)含蓄条件句
有时if条件句是以其他形式表示出来的，如上下文或介词短语形式等，常见的有but for （要不是），without， otherwise…。e.g.
1. But for you, I should be dead by now.
要不是你， 我现在早死了。
2. Without your help we couldnt have finished the job yesterday.
要不是你的帮助，我们昨天完不成工作。
3. He hesitated for a moment before kicking the ball, otherwise he would have scored a goal.在踢球前他犹豫了一下，否则的话他就会破门得分了。
（三）混杂条件句
即从句与主句的动作发生的时间不同，那么主从句谓语就依据相应的时间，使用相应的谓语。e.g.
1. If he had followed the doctors advice, he would be all right now. 要是他听从医生的意见， 他现在就好了。
2. If he had listened to me, he would not be in such trouble now.
如果他当时听了我的话， 现在就不会遇到麻烦了。

1.用于条件状语从句中
条件状语从句最典型的标志就是由if引导，虚拟语气在if引导的条件状语从句中的使用如下表：
需要注意的是，并不是所有的if引导的虚拟条件句都严格按照上表中的句式，很多情况下，if引导的虚拟条件句使用如下两种变体，这也是高考考查的难点。
1)错综时间条件句
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，主从句中的动词要根据它所表示的时间做出相应的调整。如：
If you had given him the present that evening, he would not be so angry now.
(与过去事实相反)（与现在事实相反）
He would graduate from a college in 4 years’ time if he had studied hard before.
（与将来事实相反） （与过去事实相反）
It is hard for me to imagine what I would be doing today if I ____ in love, at the age of seven, with the Melinda Cox Library in my hometown.(2002上海高考)
A. wouldn’t have fallenB. had not fallen
C. should fallD. were to fall
答案为B。
2)省略if 的虚拟倒装句
在if 引导的虚拟条件句中，有时可以省略引导词if，而把if从句中的were, had, should, would等提到句首，变成倒装句式，主句不变。如：
You didn’t let me drive. If we had driven in turn, you wouldn’t have got so tired.
→You didn’t let me drive. Had we driven in turn, you wouldn’t have got so tired.
If I were a bird, I would fly to the end of the Universe.
→Were I a bird, I would fly to the end of the Universe.
但是，如果if引导的虚拟条件句中的助动词是否定形式时，不能将其否定的缩略形式提前，而是将助动词提到句首，否定词not置于主语之后，即“助动词+主语+not+谓语”形式。如：
Were it not for the long distance, we would go camping now.
Should he not come tomorrow, we should put off the meeting till next Monday.
2.用于宾语从句中
1）用于表示建议、愿望、命令等动词后的宾语从句中。常见的这类动词有demand, order, require, insist, suggest, propose, advise等，其表示虚拟的结构为“should+动词原形”，should可以省略。例如：
He insisted that we(should) leave for the airport the time she appeared.
The teacher ordered that all the students (should) hand in their homework.
He proposed that all the directors (should) express their ideas in written forms.
不过，上述原则有两个例外：其一，当suggest表示“暗示、表明”之意时，不用虚拟语气，而应该用陈述语气；其二，当insist表示“坚持认为”之意时，不用虚拟语气，应该用陈述语气。例如：
____ be sent to work there?(2002上海高考)
A. Whom do you suggest
B. Who do you suggest that should
C. Do you suggest who
D. Do you suggest whom should
答案为A。
Her appearance suggests that she is living a happy life.
她的样子显示出她生活很幸福。
2)用于wish后面的宾语从句中。wish 后的宾语从句一般用虚拟语气，表示一种不可能实现的愿望，其构成形式为“主语+wish+that从句”，至于that从句的时态，则按照这样一个规则：a.当表示与现在事实相反时，that从句中的谓语动词用过去式；b.当表示与过去事实相反时，谓语动词用过去完成式，即“had+过去分词”形式。例如：
——William Tell was a brave man.
