虚拟语气讲解及练习题(含答案和解释)
高中英语虚拟语气讲解及练习虚拟条件句就是对现实条件的一种虚拟假设，所假设的条件一般不符合事实或与事实相反或在现实中发生的可能性极小。
根据时间的不同，虚拟条件句可分为三种，即与现在事实相反的虚拟条件句、与过去事实相反的虚拟条件句（1）表示与现在事实相反If I had enough money now, I would lend it to you.（2）表示与过去事实相反If he had taken your advice, he wouldn’t have made such a bad mistake.（3）表示与将来事实相反I would go shopping with you if it were to be Sunday tomorrow.1. 虚拟条件句的倒装在虚拟条件句中，为了强调所假设条件的虚拟性，或突出说话人的一种主观愿望，虚拟条件句可用倒装结构。
虚拟条件句的倒装是通过去掉if，把条件从句谓语中的助动词、情态动词或系动词放在句首实现的。
例如：Had I been（= If I had been ） in that situation， I would not have let the thief escape away with so much money.Should there be （= If there should be） a drought， what should we do at that time ？2. 错综时间条件句有时条件从句的动作和主句的动作发生的时间并不一致，这时谓语动词的形式应根据它所要表示的具体时间来确定。
例如：If we hadn’t been working hard in the past few years ，thing s wouldn’t be going so smoothly.3. 含蓄条件句有时假设的情况并不以条件从句的形式表现出来，而是通过某个介词或介词短语（如：with，otherwise，without，but for，in that position）、上下文或其它方式表现出来。

如果我们轮流开车，你就不会这么累了。

解析：这是针对已经发生了的事情的假设，下雪及爬山说的都是之前的事情，因此从句中用过去完成时表示虚拟，主句中用could+have done的形式表示虚拟。
注意：此句中涉及一个it的句型。
It is for …一般用于引起原因，If it isn’t for …，意为“要不是因为……”。
此句中用了该句型的虚拟语气形式。
4. The new airport _______ if they had not stopped working on it.A. would completeB. had been completedC. had completedD. would have been completed句意：如果他们没有停止建设，新机场早就建成了。

新机场是被建成，这里有一个完成加被动。
5. If he _______ his doA. had taken, might still have beenC. might have taken; had still beenD. took; might still be句意：如果他听了医生的建议，他现在可能还活着。
解析：这是错综时间条件句，从句说的是过去听医生的建议，主句说的是现在的情况。

A. were; would have letC. had been; had letD. were; had let句意：如果你是健康的，昨天我就会让你去旅行了。
解析：这是针对已经发生了的事情的假设，健康状态及旅行说的都是昨天的事，因此从句中用过去完成时表示假设，主句中用would+have done的形式表示假设。

解析：这是表达主观意愿的虚拟语气。

9. The boss insisted that John ________ unfit for his work.A. wasB. isC. should beD. were句意：老板坚持认为John不称职。
解析：该句中没有虚拟语气，是直陈句，从句时态与主句时态应一致，都为一般过去时。

解析：该句中没有虚拟语气，从句的时态与整个句子的时态保持一致。
句子是一般过去时，而找到工作是在回家之前发生的，所以要用过去完成时。
该句中的suggest意为“表明、意味着、暗示”，不表示“建议”，因此不用虚拟语气。
13. Most of the members demanded (requested, required, asked) that the meeting________ till after Friday.A. shouldn’t put offB. not be put offC. wouldn’t be put offD. not put off 句意：大部分成员要求会议不要推迟到周五以后。

这里相当于是should not be put off，省略了should。
14. I wish I ________ how to translate this sentence.A. knewB. knowC. have knownD. should know句意：我希望我知道如何翻译这个句子。
解析：这是表达非现实的愿望。
Wish后的that从句中，如果是针对现在的时间而言，那么动词用过去时表示非现实的愿望。
