(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。

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。
