高考英语 语法复习 专题8 情态动词和虚拟语气 精品导学案(含解析)
高考英语语法复习专题8 情态动词和虚拟语气精品导学案（含解析）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。
1．虚拟语气在条件句中的用法If it were to rain tomorrow, I should not drive my car. 如果明天下雨的话，我就不开车了。
(明天的情况还不知道)If I had done it in time, I should have had a good time. 如果我及时做的话，日子就好过多了。

M6 U3 Grammar Unreal conditionals 虚拟语气【学习目标】Students are expected to learn when to use Unreal conditionals and how to use Unreal conditionals.【知识准备】英语中的语气分为述语气、祈使语气、虚拟语气三类。
虚拟语气用来表示说话人的主观愿望或假想，而不表示客观存在的事实，所说的是一个条件，不一定是事实，或与事实相反。
虚拟语气通过谓语动词的特殊形式来表示。
条件状语从句分类条件句可分为两类，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或实际可能性不大的情况，故采用虚拟语气。
eg： 1. If he doesn't hurry up,he will miss the bus.2.If he is free,he will ask me to tell stories.3.If I were you,I would go at once.4.If there were no air,people would die.以上四句中和是真实语气；和是虚拟语气【自主探究】一、状语从句中的虚拟语气(一) if 引导的条件状语从句1 If I had time, I would attend the meeting.2.

（二）：条件状语的倒装：如果条件状语中有were, had, should时, 可以倒装成：Were / Should / Had +主+其他1. If I were you, I would try it again. ___________________, I would try it again.2. If he had been there yesterday, he would have seen the film._______________ there yesterday, he would have seen the film.3. If it should snow tomorrow, we wouldn’t go out. _____________ tomorrow, we wouldn’t go out.注意：在省略句型中，只有had done 的had 才能省略，实义动词had 不能省。
1If I had time now, I would go to the library. Had I time now, ……. (误）（三）．错综时间条件句：假设条件从句谓语动词发生的时间与主句所假设的谓语动词不一致，叫做错综条件虚拟语气。
主句和从句的谓语动词要依照假设的时间而定。
1. If the weather had been fined, the crops would be growing still better.2. If you had followed the teacher’s advice, you wouldn’t be in the hospital.3. If you had come and attended the meeting yesterday, you __________(know) what we are doing now.4.If you __________(take) my advice then, you _________________________(现在就不会有麻烦了)5. _____ her husband _________(kill) in the war, she would not be helping others with housework now.（四）：含蓄条件句：有时虚拟的条件不是通过条件句来表示，而是用一些词或短语，如without, but for, or , otherwise等，这种句子叫含蓄条件句。
1. But for electricity ( = If it were not for electricity ), there would be no modern industry.2. Without your help (If it had not been for your help), we could not have succeed.3. I was ill that day. Otherwise, I would have taken part in the sports meet.
