人教版高二英语必修六语法点の虚拟语气

人教版高二英语必修六语法点の虚拟语气

人教版高二英语必修六语法点の虚拟语气人教版高二英语必修六语法点の虚拟语气虚拟语气表示一种不能实现的假设。

该语法主要用于if条件状语从句。

一、if引导的条件状语从句的分类及虚拟条件句的判断1、可以把条件句分为两类:1).真实条件句:凡是假设的情况发生性可能很大,就是真实条件句。

例如:(1)、If I have time, I will help you with this work.如果我有时间会帮助你做此工作的。

(2)、If time permits, we’ll go fishing together. (如果有时间的话,我们就一起去钓鱼。

)2).虚拟条件句:当假设是不大可能实现时,就是虚拟条件句。

例如:⑴、If I were you, I would have attended the meeting.如果我是你的话,就去参加会议了。

⑵、If he had come here yesterday, he would have seen his old friend.假如他昨天来这儿的话,就会看见他的老朋友。

(3)、If it had rained yesterday, we would have stayed at home.(如果昨天下雨的话,我们就会留在家里。

)2、if条件状语从句中虚拟语气的判断判断是真实条件句还是非真实条件句。

只有在非真实条件句中才使用虚拟语气。

通过句子意思,看假设的条件是否能够实现,能够实现是真实条件句,不能使用虚拟语气;假设的条件不能实现则是非真实条件句,要用虚拟语气。

判断这个假设是与哪个事实相反。

通常有三种情况:①与过去事实相反。

②与现在事实相反。

③与将来事实可能相反。

3、“后退一步法”后退一步法是指在准确地判断了该句与哪一事实相反后,按虚拟语气的后退一步法处理从句谓语动词的时态。

即:在非真实条件状语从句中,谓语动词按正常情况“后退一步”。

也就是:①与过去事实相反,在从句中用过去完成时形式表示。
