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。
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。
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。

高中语法专题解析虚拟语气的条件句
高中语法专题解析虚拟语气的条件句虚拟语气是英语语法中的一个重要部分，高中阶段也是学生们较为困惑的一个语法点。
虚拟语气主要用于表示假设、愿望、建议和命令等情况。
本文将针对高中语法专题解析虚拟语气的条件句进行详细论述。
一、虚拟语气的基本概念虚拟语气是一种用来表示非现实情况的语法形式，它与事实相反或者与现实无法达成的情况相关。
虚拟语气主要通过词法和语法上的变化来实现，主要包括条件句中的“if”引导的虚拟条件句、愿望句、建议句和命令句。
二、虚拟语气的条件句虚拟语气的条件句是指条件从句中表达虚拟的情况。
条件句中包含一个虚拟条件，它与实际情况相反或者与现实无法达成。
在虚拟语气的条件句中，常见的谓语动词有三种形式：过去时的虚拟形式、would/could/might+动词原形和should+动词原形。
1. 虚拟语气的条件句假设与现实相反：例如：If I were a bird, I would fly in the sky.这个句子中，条件从句中的“were”是“be”动词过去时的虚拟形式，表示与现实相反的假设情况。
2. 虚拟语气的条件句假设与现实不符：例如：If I had studied harder, I would have passed the exam.这个句子中，条件从句中的“had studied”是过去完成时的虚拟形式，表示与过去的事实不符的假设情况。
3. 虚拟语气的条件句用于表示建议或命令：例如：If you were to go to the party, you should dress formally.这个句子中，条件从句中的“were to go”和主句中的“should dress”分别表示建议和命令的虚拟语气条件句。
三、虚拟语气的用法注意事项在使用虚拟语气的条件句时，需要注意以下几个方面：1. 用虚拟语气表示非真实或假设的情况；2. 主句中的动词要使用虚拟语气，可通过过去时、情态动词或should+动词原形来实现；3. 如果条件从句中的主语是第一人称单数形式，动词要使用过去时的虚拟形式“were”而不是“was”。
