高中英语2025届高考语法复习虚拟语气知识讲解
高考英语语法复习虚拟语气知识讲解一、基础知识（一）什么是虚拟语气谓语动词的作用不仅可以表示动作的时间、状态、假设（情感），也是一种语气（mood)的表现形式，表明说话的目的和意图。
（语气包含陈述语气、祈使语气、虚拟语气、疑问语气）虚拟语气用于表示假设、愿望、建议、命令等非真实或虚拟的情况，即与真实相反。
上学的时候老师经常举的一个例子，"If I were you"因为我不可能是你，这是一种不可能存在的事实，所以这是个虚拟语句。
总而言之英语中的虚拟语气可以分为两大体系：一是表示与事实相反的，或者是假象的情形，通常由if引导，叫做虚拟条件句；另一个体系是在名词从句中使用虚拟语气，表示建议，命令或者要求等语气，类似于上述美剧常用的台词。
（二）虚拟语气的用法这一部分我们主要用虚拟语气在条件句中的用法作为讲解与现在事实相反：If I had a map, I would lend it to you.如果我有地图我就借给你。
（但我没有）与将来事实相反：If I were to do the job, I would do it in a different way. 要是我来做这工作，我会是另一种做法。
（言外之意不是我做这个工作，用虚拟表达是我做这份工作的可能性很低）与过去事实相反：If anything had happened, he would have let us know.如果发生了什么情况，他早就通知我们了。
（所以没事发生）它们的共性都是表示与事实相反或者实现可能性不大3.特殊情况①在极少情况下，从句的谓语动词用原形，主句的谓语动词可用陈述语气（比较官方，正式，大气的说法，口语很少使用）If that be the official view, it cannot be accepted.如果这是官方的看法，这是不能接受的。
②if可以省略，但是语序要改为倒装Were I Tom I would refuse.如果我是汤姆我会拒绝。
高考英语语法精品学案：专题8 情态动词和虚拟语气.doc
情态动词主要用来表示说话人的情感、态度等，是中学英语语法的重点，也是高考的热点，是单项填空必考的一个知识点。
情态动词在近五年高考中主要考查四点：情态动词表示推测和可能性的用法；情态动词与虚拟语气；情态动词表达“情感、态度、语气等”；情态动词表示“必要性”等方面的用法。
虚拟语气的考点主要集中在名词性从句、条件句中的用法，以及错综条件句中虚拟语气的应用。
一、情态动词表推测的用法It must beMr. Wang.He looks likeourheadmaster.②That may not be true.③He couldn't have discoveredthe truth.注意：should (ought to)表示推测是高考考查的重点和难点。
如：—When can I come for the photos？I need them tomorrow afternoon.—They ________ be ready by 12：00.A．can B．should C．might D．need【解析】B A项表示推测时常用于否定句和疑问句中。
C项表示推测语气不太肯定。
should意为“按理说，理应”，既回答了顾客的询问，不失礼貌，又为照片有可能尚未洗好，顾客到时取不到留下了回旋的余地，体现了店主的精明与用词经过仔细推敲。
二、情态动词的其他用法1．can, could, may, might2.must, should3. need, dare4.shall/will/would4.shall/will/would4.shall/will/would二、情态动词＋have done四、虚拟语气虚拟语气表示说话人所说的话不是事实，而是一种假设、愿望、怀疑或推测。

语从句、定语从句等。
1. 虚拟语气在主语从句中的应用“常用在It is (was)+形容词形容词/ 过去分词+that 引导的主语从句”的句型中的主语从句要用虚拟语气。
