六年级英语专项练习：情态动词一、情态动词的定义：情态动词有词义，但它不能单独作谓语，它必须和其他动词一起构成谓语。
情态动词没有人称和数的变化；它的后面必须跟动词原形。
二、情态动词的种类：情态动词有can (could), may, must, have to, shall (should), will (would), need等，这些是小学阶段需掌握的情态动词。
三、情态动词的用法：一、can, (could 过去式）1) 表示能力（体力、知识、技能）。
Can you lift this heavy box?（体力）Mary can speak three languages.（知识）Can you skate?（技能）2) 表示请求和允许。
Can I go now?Could \Can you help me? ---- Yes, of course.\Certainly.\ Sure.Could \Can you tell me the way to the Zoo?3) 表示推测（惊讶、怀疑、不相信的态度），用于疑问句、否定句和感叹句中。
Can this be true?This can’t be done by him.How can this be true?二、may1) 表示请求和允许。
否定回答时可用can’t 或mustn’t，表示“不可以，禁止”。
---- May I smoke in this room?---- No, you mustn’t.---- May I take this book out of the room?---- Yes, you can. (No, you can’t / mustn’t)用May I...？征徇对方许可时比较正式和客气，而用Can I...？在口语中更常见。
2）表示推测、可能性（不用于疑问句）。
1．He may be very busy now.2．Your mother may not know the truth.3）用于祈使句，表示祝愿。
May you succeed!三、must, have to1) must表示必须、必要, 带有命令强制口气；而have to表示不得不，很勉强，强调客观需要。
You must come in time.We must help each other.My sister is ill; my mother has to look after her.I had to work when I was your age.注意：must的否定形式mustn’t表示禁止，意思是“不能，不许”。
在回答由mu st引起的疑问句时，如果是否定的，不能用mustn’t（禁止，不准），而用nee dn’t,don’t have to（不必要）。
---- Must we hand in our exercise books today?---- Yes, you must.---- No, you don’t have to / you needn’t.2) must表示推测、可能性（只用于肯定的陈述句），意思为“一定是,必然……”。
