問句 肯定回答 否定回答
Need you…? Yes, I must. No,I needn't
Must you…? /don't have to.
典型例題
1)---Could I borrow your dictionary?
---Yes, of course, you____.
A. might
B. will
C. can
D. should
答案C.could表示委婉的語氣,并不為時態。答語中of course,表示肯定的語氣,允許某人做某事時,用can和 may來表達,不能用could或might。復習: will 與you連用,用來提出要求或下命令。should與you 連用,用來提出勸告。
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 將不, 不會的。 mustn't 禁止、不能。 shouldn't 不應該。本題為不需要,不必的意思,應用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既可當作情態動詞,表請求、建議、也可作為實義動詞表"意愿、意志、決心",本題表示決心,選B。
