Question

-No，you           ．（　　）

• A． mustn't
• B． needn't
• C． can't
• D． shouldn't

Answer 1

分析 --我必須立刻去那里嗎？
--不，你不必．

解答 答案：B．can't不可能；mustn't不可以；shouldn't不應(yīng)該；needn't不必．根據(jù)Must，可知這里是以must開(kāi)頭的一般疑問(wèn)句，對(duì)于must引導(dǎo)的一般疑問(wèn)句，肯定回答用must，否定回答用needn't或don't have to來(lái)回答，根據(jù)No，可知不必立刻去那里．故選B．

點(diǎn)評(píng) 本題考查了情態(tài)動(dòng)詞的用法．解答時(shí)注意對(duì)于must引導(dǎo)的一般疑問(wèn)句，肯定回答用must，否定回答用needn't或don't have to來(lái)回答．
