虚拟语气在宾语从句中的用法
虚拟语气在宾语从句中的用法虚拟语气在宾语从句中的用法主要是表示一种与事实相反或不可能实现的假设、愿望、建议、命令等。
常用的虚拟语气形式有虚拟条件状语从句的"if"引导的虚拟语气、愿望句型的虚拟语气以及建议、命令等句型的虚拟语气。
1.虚拟条件状语从句的"if"引导的虚拟语气：在宾语从句中，如果条件句表达的是不可能实现或与事实相反的情况，那么主句的谓语动词就可以采用虚拟语气来表达。
例如：- I wish he were here.（我希望他在这里。
）其中，"were"是虚拟语气的过去式形式，用于表示与现实相反的情况，即实际上他不在这里。
2.愿望句型的虚拟语气：在宾语从句中，如果表达的是一种渴望或愿望，而该愿望实际上是不太可能实现的，那么常常使用虚拟语气来表达。
例如：- I would rather you came tomorrow.（我希望你明天来。
）其中，"came"是虚拟语气的一种形式，用于表示与现实相反的情况，即实际上他未来。
3.建议、命令等句型的虚拟语气：在宾语从句中，如果主句是一个建议、命令等，而宾语从句所表示的内容是不可能实现或与事实相反的情况，那么主句的谓语动词也可以采用虚拟语气来表达。
例如：- The teacher asked that he not be late for class.（老师要求他不要迟到。
）其中，"be"是虚拟语气的一种形式，用于表示与现实相反的情况，即实际上他经常迟到。
虚拟语气在宾语从句中的使用可以使句子更丰富多样，并能够准确表达说话人的想法、意愿和假设。
但需要注意的是，虚拟语气用法的正确性与自然性需要根据具体情况和语境来判断。

虚拟语气用法总结
虚拟语气用法总结虚拟语气是说话者用来表示假设，或难以实现的情况，而非客观存在的事实。
学习虚拟语气，我们需要注意以下几个要点：一、虚拟语气在带有条件状语从句的复合句中的构成和用法。
根据不同的时间，主、从句中动词形式如下表：If we left now, we would arrive in good time. 如果我们现在就走的话，我们就会及时到达。
They would have come to your party if they had had time. 如果他们有时间就会参加你的聚会。
If you lived there for a while, you’d change your mind about the place. 如果你在那儿住上一段时间，你就会改变对那地方的看法。
这里我们需要注意以下三点：1. 错综时间条件句有时条件状语从句中的动作和主句中的动作发生的时间不一致，这时动词的形式要根据它所表示的时间加以调整。
如：If you had listened to the doctor, you would be all right now. 如果你当初听了医生的话，身体现在就好了。
2. 虚拟条件句的倒装形式如果虚拟条件从句中有were, had或should时，可以把if省略，而把这几个词放到主语之前，构成倒装句。
如：Were I you, I wouldn’t go there alone. 如果我是你，我不会一个人去那儿的。
Had he worked harder, he would have got through the exam. 如果他学习再努力点的话，他就会通过考试。
Should you be fired, your health care and other benefits will not be immediately cut off. 如果你被解雇，你的医疗保险和其他权益并不会立即中断。

高中虚拟语气用法解析（完整版）一．虚拟语气在非真实条件句中的应用非真实条件句：if引导的条件状语从句，但是实现该条件的可能性极小或不可能实现1.表示与过去事实相反Eg.If my car had been more reliable,I would have driven to my office.2.表示与现在事实相反Eg.In fact,it is certain that we would not be able to understand it if we heard it today.3.表示与将来事实相反Eg.If you succeed,everything would be all right.Grace doesn't want to move to New York because she thinks if she were to live there,she wouldn't be able to see her parents.4.注意事项(1)W as不可以替代were，虚拟语气中，从句中be动词只有were(2)错综时间条件句：条件句的行为和主句行为发生的时间不一致，动词的形式按照主句和从句各自的时间调整。
Eg.If he had listened to me, he would not be in such trouble now. If it had not been raining too much, the crops would be growing much better.(3)虚拟条件句中的谓语动词含有were/ should /had 时，if可省略，而将were/ should /had 置于主语前面Eg.What would have happened had Bob walked farther as far as the river bank?Should he agree to go there, we should send him there. Were it Sunday tomorrow, we should go to the great wall.两个固定搭配：①Were it not for 要不是...就②Had it not been for 要不是...就If it were not for （Were it not for）the bad weather now, we would go to the park to fly kites.If it had not been for（Had it not been for） the bad weather yesterday, we would have gone to the park to fly kites. （4）含蓄虚拟条件句：有时假设的情况不是以if条件句来表示。
