高中英语语法——情态动词总结(附带练习)
(完整)英语语法 情态动词及练习题
情态动词一、知识梳理/提炼1. can和could的用法表示能力或客观可能性,还可以表示请求和允许。
如：Can you finish this work tonight?Man cannot live without air.— Can I go now？— Yes， you can.注意:①could也可表示请求,语气委婉，主要用于疑问句，不可用于肯定句，答语应用can （即could不能用于现在时态的简略答语中）。
如：Could I come to see you tomorrow？Yes, you can。
(否定答语可用No， I'm afraid not。
）②can表示能力时,还可用be able to代替。
如:I'll not be able to come this afternoon。
2。
may和might的用法1)表示许可.表示请求、允许时，might比may的语气更委婉一些,否定回答时要用mustn't表示“不可以"、“禁止"、“阻止”之意.如：You may drive the car.— Might I use your pen? — No，you can’t/ mustn't. Yes, you can/may. 用May I .。
. 征询对方许可在文体上比较正式，在口气上比较客气。
在日常口语中,用CanI ... 征询对方意见在现代口语中更为常见.2) 用于祈使句中表示祝愿.如：祝你成功！ May you succeed！3)表示推测、可能（疑问句不能用于此意）。
他现在可能很忙. He may be very busy now。
3。
must和have to的用法1) 表示必须、必要。
如:You must come in time.回答must引出的问句时,如果是否定的回答，不能用mustn't,而要用needn't或don't have to。

考点讲解：概述情态动词（Modal Verbs）是用来表示能力、允许、预言、可能性、建议、情感、态度等的含义的一类动词。
我们使用缩写modal v.来表示情态动词。
情态动词属于不完全动词，因此情态动词不能独自在句中作谓语，即其后需要一个实义动词和情态动词共同在句中作谓语。
这样的谓语一般也称作“复合谓语”，属于复合谓语中的一种类型。
一般地，情态动词后面接不带to的动词不定式，即动词原形。
一般地，情态动词具有助动词的语法属性，可以完成一些语法功能的需要（比如可以构成否定句或疑问句等）。
有一些情态动词有相应的过去式的形式，有一些则没有（如must 等）。

②can't在口语中代替mustn't时，表示禁止或不准。

情态动词和have done知识点总结与练习讲义(含解析)新高考英语语法微专题培优复习
2021届新高考英语语法微专题培优复习情态动词与have done知识点总结与练习（含解析）情态动词在高考题中的考察非常直接，主要考察以下两方面：1、情态动词的本义2、情态动词与have done咱们今天先把简单的解决了，就是情态动词与have done。
这东西在考试里就俩方向，一个表示对过去的推测，一个表示对过去的虚拟。
注意，只要情态动词加了have done，一定表示“过去”的事。
1、表示对过去情况的推测must have done / can't have donecould have done / couldn't have donemight (may) have done / might (may) not have done三者的语气按照must — could — might的顺序依次递减，表示对于推测准确性的把握在逐步降低。
当然，在题目当中我们并不需要掌握三种语气的差异，只要观察题目中有没有出现推测的证据，或者证据是否确凿，即可作出语气强或弱的判断。
有证据，就强；没证据，就弱。
2、表示对过去情况的虚拟should have done本应该责备语气shouldn't have done本不应该责备语气could have done本可能遗憾/惋惜语气couldn't have done本不可能意外/惊喜语气needn't have done本不必多余/不必要语气表示虚拟时，句中一定可以加入“本来……”这样的口吻。
请注意，每种虚拟都有自己的使用场合，进而传达出在该场合下需要体现的语气和态度。
把两方面合并在一起，我们就会发现，情态动词+have done的结构，其实可以这样来方便记忆：must / might (may) 推测+could 推测/虚拟+should / need 虚拟must和might肯定是推测，should和need肯定是虚拟，只有could一个同时身兼两种功能，所以遇到的时候要注意判断。
