高中英语虚拟语气讲义1
名词性从句中的虚拟语气(讲义)
1. 通过本课的学习，能够全面掌握名词性从句中虚拟语气的基本用法。
2. 通过本课的学习，能够初步了解虚拟语气在不同类型名词性从句中的具体用法。
重点：掌握与坚持、命令、建议、要求四类词相关名词性从句中虚拟语气的用法。
难点：wish宾语从句中虚拟语气的用法。
近几年高考对于虚拟语气的考查主要集中在语法填空和书面表达中，语法填空涉及动词提示词的填空中多次出现对虚拟语气的考查，考查难度不大。
一、主语从句中的虚拟语气：1. It is／was + 形容词+ that从句当形容词为important, necessary，strange，natural，appropriate, proper, right, desirable, essential, surprising, unthinkable等或名词短语a good idea时。
2. It is／was + a pity / a shame / a surprise / no wonder + that从句3. It is demanded / suggested / ordered / required / ….that-clause注意：这种主语从句由连词that引导，虚拟语气为“（should）动词原形”。
其中should可省略。
should 常译成“应该、必须、竟然”。
It is important and necessary that we (should) master a foreign language.精通一门外语对我们来说是重要而且必要的。
It is proper that an independent inquiry (should) take place.进行独立调查很合适。
It is strange that he (should) refuse your help.他竟然拒绝你的帮助真是奇怪。
It is surprising that you (should) not understand me!你竟然不理解我，真令人吃惊！It’s a pity that you (should) miss a good chance.你竟然错过一个好机会真是遗憾。

高中英语虚拟语气语法讲解(有答案)
高中英语虚拟语气语法讲解虚拟语气是一种动词形式，表示说话人的一种愿望，假设，怀疑，猜测，建议等含义，虚拟语气所表示的含义不是客观存在的事实。
在条件句中的应用，条件句可分为两类，一类为真实条件句，一类为非真实条件句。
非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。
一、虚拟语气在从句中的使用虚拟语气即表达不可能发生或与预期相反的情况。
首先我们应熟悉它在三种时态里的使用情况，这是正确使用虚拟语气的基础。
这三种时态是：现在；过去；将来。
1、表示现在的虚拟式If I were a bird, I would fly to you. 如果我是只鸟，我就会飞到你身边去。
If it were not for their help, we should be in a very difficult position. 如果不是他们的帮忙，我们就会处于一个非常困难的境地。
2、表示过去的虚拟式If we had started earlier, we should not have missed the train.如果我们早一点动身的话，就不会误车了。
If she hadn’t been ill, she might have come. 如果她不是病了，可能会来的3、表示将来的虚拟式If Professor Li should have time tomorrow, we could ask him some questions.如果李教授明天有空的话，我们可以问他点问题。
If there should be no air, there would be no living things.如果没有空气，就不会有生物。
二、错综时间的虚拟句通常情况下,在非真实条件句中主句和从句的谓语动词所指时间是一致的, 但有时也可能指不同的时间,这时要根据上下文的意思采用不同的谓语动词形式.If I were you, I would have taken his advice. (从句指现在, 主句指过去)。

虚拟语气
知识导图
虚拟语气的定义：虚拟语气表示说话人的某种愿望、假设、怀疑、猜测和建议等，表示的是纯属假设或实现的可能性不大的情况。
虚拟语气是由句中的谓语的特殊形式表现出来的。
虚拟语气的用法
1.虚拟语气用于条件句（条件状语从句）
①条件句的分类
条件句可以分为两种：真实条件句和虚拟条件句。
真实条件句是一种可能实现的条件句，且实现的可能性非常大。
在条件句中常用表示现在的某种时态代替表示将来的时态。
If I have time, I’ll come over to see you.
虚拟条件句是一种表示不能实现或实现的可能性很小的条件句。
其谓语动词用虚拟语气。
If I had time, I should/would/could come over to see you.
