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。

(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。

如：He could write poems when he was 10. 他十岁时就会写诗。
（2）. could在疑问句中，表示委婉的语气，此时could 没有过去式的意思。
如:____________________? 你能帮我个忙吗？—Could I use your pen? 我能用一下你的钢笔吗? —Yes, you can.可以。
（注意回答，你再想想否定回答用什么呢）3. may的用法：（1）.表示请求、许可，比can 正式，如：May I borrow your bike? 我可以借你的自行车吗？You may go home now. 现在你可以回家了。
边学边练：—_______ I borrow your MP3? —Sure . Here you are. A. May B.Should C.Must D. Would（疑点扫描：关于它的可定和否定回答如何呢？）(2) .表示推测，谈论可能性，意为“可能，或许”，一般用于肯定句中。
如：It may rain tomorrow . 明天可能会下雨。
She may be at home. 她可能在家呢.(3) .may的过去式为might ，表示推测时。
可能性低于may。
如：______________________________他离开学校了，可能是他生病了。
(4) . 表示希望、祈求、祝愿，常可译为“祝愿”。
通常是用may +主+V 例如：May you have a good time. 祝你过得愉快。
May you be happy! 祝你幸福！May you succeed！祝你成功！注意：may的位置4. must的用法：(1).must 表示主观看法，意为“必须、一定”。
如：_________________________在我回来之前你必须呆在这儿。
Must I hand in my homework right now? 我必须现在交作业吗？（空间转移：你想过have to 吗？）(2) 其否定形式mustn’t表示“一定不要”“千万别”“禁止, 不许”. 如：_____________________ 你不许玩火。
You mustn’t be late. 你一定不要迟到。
（错误认知：在表推测时不要将它的否定形式理解为“一定不”，无推测）（3）对must引导的疑问句，肯定回答为must，否定回答为needn’t 或don’t have to .如：—Must I finish my homework?我现在必须完成作业吗？—No, you needn’t.不，你不必。
(4)must表示有把握的推测，用于肯定句。
如: The light is on, so he must be at home now.灯亮着，他现在肯定在家。
注意其反意问句的构成形式：当must表示肯定的判断、推测时，其反意疑问句要用实际问句的助动词来构成。
如：She must have seen the film before，hasn’t she?(注意反意疑问句的后半部分)You must have met uncle Wang in the shop yesterday，didn’t you? (注意反意疑问句的后半部分)5. need的用法：（1）.need 表示需要、必须，主要用于否定句和疑问句中，其否定形式为needn’t，意为“没有必要，不必”。
用need 提问时，肯定回答为must，否定回答为needn’t或don’t have to。
如：—Need I stay here any longer? 我还有必要留在这儿吗？—Yes, you must .是的。
—No. you needn’t /don’t have to.不，你不必。
(瞻前顾后：想一想前面讲过的must的肯定与否定回答)(2).need 还可以作实义动词，此时有人称、数和时态的变化，如果是人作主语后边多接动词不定式。
如：I need to do it right now. 我需要马上做这件事。
He needs to learn more about the girl.他需要多了解那个女孩。
解题之“渔”在need的词性方面你应做到1.它作为情态动词有单三式吗？____________________________2.它作为情态动词之前可加助动词吗？______________________3.它在一般疑问句中不提前是情态动词吗？__________________如果是物作主语，一般用need doing 与need to be done这种情况下应注意两点：①.主动形式的动名词doing具有被动的含义；②.该动名词可以改为其动词不定式的被动形式而句子的意义不变。
例如：___________________= __________________那扇门需要油漆一下。
Your car needs mending. = Your car needs to be repaired. 你的车需要维修了。
7. shall 的用法：shall表示征求对方意见（多用于第一、三人称），如：Shall we go out for a walk? 我们出去散步好吗？在英语中，我们可以用其他多种方式提出我们的建议或征求对方意见。
你来总结：对于提建议的几种方式会有几种___________________________________________________________________ ___________________________________________________________________ 你应注意：（这几种方式后的动词形式一样吗？）__________________________________________________________________ 8. should的用法：（1）.should 意为“应该”，可表示劝告、建议、义务、责任等。
如：We should protect the environment. 我们应该保护环境。
（2）Should have done 表示对过去动作的责备、批评。
如：You should havefinished your homework.你应该已经完成作业了。
（事实上你没有完成。
）9. will 的用法：will表示意愿、意志、打算，可用于多种人称。
如：I will help you if I’m free this afternoon.今天下午如果我有空，我就会帮你。
思维大挪移1、will在there be句型中的形式及其句式变换。
（想一想一般将来时与there be 句型的结构，你会发现什么2、will 与be going to do sth区别：①. be going to 表示近期、眼下就要发生的事情，will 表示的将来时间则较远一些，如：He is going to write a letter tonight. He will write a book one day.②. be going to 表示根据主观判断将来肯定发生的事情，will表示客观上将来势必发生的事情。
He is seriously ill. He is going to die. He will be twenty years old.③. be going to 含有“计划，准备”的意思，而will 则没有这个意思，如：She is going to lend us her book.He will be here in half an hour.④.在有条件从句的主句中，一般不用be going to, 而多用will, 如：If any beasts comes at you, I'll stay with you and help you10. had better 的用法：had better 意为“最好”，没有人称的变化，后面接不带to 的不定式，其否定形式为：had better not。
如：____________________________我们最好现在就走。
_______________________________.你最好不要把这本书给他。
