14．--Must we clean the room at once？
--No，you____．You can do it after school．（　�。�
A．mustn'tB．needn'tC．can't

分析 --我們必須立刻打掃房間嗎？
--不，你不必．你可以放學(xué)以后打掃它．

解答 答案：B．
根據(jù)No和You can do it after school．可知下面為否定回答，must的含義是必須一定，其否定形式mustn't表示禁止的含義．在這里不是禁止的意思．must的否定回答一般可借助于needn'和don't have to來構(gòu)成，表示不必．故選B．

點(diǎn)評 本題考查了情態(tài)動(dòng)詞的用法．注意must的用法以及它的肯否定形式．
