'情態動詞的回答方式'

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，並不為時態。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。複習： 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"意願、意志、決心"，本題表示決心，選B。
