— May we leave the classroom now?
— No, you _______. You _______ to leave until the bell rings.| A．mustn’t; are allowed | B．can’t; aren’t allowed | | C．don’t have to; are allowed | D．needn’t; aren’t allowed |
|
答案
| B |
解析
试题分析：may的否定回答应该用can’t，表示不能，不可以；而mustn’t表示禁止，一般不做否定回答；don’t have to表示不必；needn’t是must的否定回答，表示“不必”。所以本题选B。
点评：本题可以只根据第一个空做出选择，第二个空是一个被动语态，本句表示“直到铃响你才能出去。”你是被允许的。 |
