问句 肯定回答 否定回答

Must you…? /don't have to.
典型例题
1）---Could I borrow 1 your dictionary 2?
---Yes, of course 3, you____.
A. might 4 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 5.
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。
