课堂小结 本课我们分别介绍了情态动词can 和cannot, may和may not, must和must not的相关用法。鼓励学生运用must和must not来制定规定。
板书 情态动词情态动词具有一定的词义,但不能独立存在,须与动词原形一起构成谓语,表示说话人对动作的观点,如意愿、需要、可能或怀疑等。情态动词有时态的变化,但大多数没有人称和数的变化。【情态动词can的用法】can 可表示能力,意为“能;会”,相当于 be able to;也可表示许可或请求对方允许,意为“可以”。须注意:could 是 can 的过去式,但表示请求许可时,could 和 can不表示时态的区别,只是 could 的语气更加委婉,用 could 提出的请求要用 can 来回答。can 的否定式为 cannot / can’t,意为“不能;不会”或“不可以”,还可表示“可能不”。can 构成的一般疑问句及其回答形式如下:— Can you ... — (肯定回答) Yes, I can.— (否定回答) No, I cannot / can’t.如:Mary can ride a bike, but she cannot drive a car.Can I borrow your eraser Could you show me how to use the mobile phone 【情态动词may的用法】may 表示许可或请求对方允许,意为“可以”,相当于can。两者的区别在于:表示请求许可时,may 更能表示礼貌或敬意。may 的否定式为 may not,意为“不可以”。may 构成的一般疑问句及其回答形式如下:— May I ... — (肯定回答) Yes, you may / can.— (否定回答) No, you may not / can’t /mustn’t. (注:mustn’t的语气最强,表示禁止。)如:You may / can go home now.— May I have lunch now, Mum — No, you may not. You should wash your hands first.【情态动词must的用法】must 表示规定、命令、强制,意为“必须;一定”。 must 的否定式为 must not / mustn’t,意为“禁止;不准”。must构成的一般疑问句及其回答形式如下:— Must I ... — (肯定回答) Yes, you must.— (否定回答) No, you needn’t如:You must go home before 10 p.m.You mustn’t speak too loud here.— Must I clean the floor now — No, you needn’t.【辨析】意义用法must“必须;一定”强调主观上必须做某事have to“不得不;必须”强调客观上不得不做某事
