情态动词的回答方式

问句 肯定回答 否定回答

Need you…? Yes, I must. No,I needn't

Must you…? /don't have to.

典型例题

1)---Could I borrow your dictionary?

---Yes, of course, you____.

A. might B. will C. can D. should

答案C.could表示委婉的语气，并不为时态。答语中of course，表示肯定的语气，允许某人做某事时，用can和 may来表达，不能用could或might。复习： will 与you连用，用来提出要求或下命令。should与you 连用，用来提出劝告。

2)---Shall I tell John about it?

---No, you ___. I've told him already.

A. needn't B. wouldn't C. mustn't D. shouldn't

答案A。needn't 不必，不用。 wouldn't 将不, 不会的。 mustn't 禁止、不能。 shouldn't 不应该。本题为不需要，不必的意思，应用needn't。

3)---Don't forget to come to my birthday party tomorrow.

---______.

A. I don't B. I won't C. I can't D. I haven't

答案B. will既可当作情态动词，表请求、建议、也可作为实义动词表"意愿、意志、决心"，本题表示决心，选B。
