高二英语Unit 1 Grammar 虚拟语气知识精讲新人教版选修6一、学习目标：1. 学习虚拟语气在条件句中的应用。

2. 掌握虚拟语气使用的语境与方法。

二、重点、难点：虚拟语气在条件句中的句型结构。

三、考情分析：在高考题中，目前全国19套各地市试题中涉与到虚拟语气知识点的占30%以上，因此这一语法项目在高考中变得越来越重要。

这一知识点经常以单项选择题的形式出现，分值为1分。

而且，我们在日常对话中也会经常用到虚拟语气。

四、知能提升〔一〕知识讲解【认知讲解】教材原句呈现①If you were an artist, what kind of pictures would you paint?②If the rules of perspective had not been discovered, no one would have been able to paint such realistic pictures.③Have you ever wished you could paint as well as a professional artist?比照分析第一个句子中的从句显然是做了一个不可能成立的假设，这是一个与现在事实相反的虚拟语气的句子。

第二个句子中如此是与过去事实相反，是表示如果透视法没有被发现，就没有人能够画出这样具有现实主义的画来。

第三个句子中wish后面的虚拟语气，表示与将来事实相反。

【重、难点】1〕虚拟语气可以用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。

虚拟语气在条件句中应用得比拟多。

2〕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发生的可能性不大的情况，故采用虚拟语气。

I.真实条件句用于陈述语气，所假设的情况有可能发生。

结构如下所示：从句往往用一般现在时，而主句如此由“shall/will + 动词原形〞构成。
