题目
题型:不详难度:来源:
— Must we get to the airport before 8 o’clock?
— No, you _____. The plane takes off at 12 o’clock.
A.mustn’tB.needn’tC.wouldn’tD.shouldn’t

答案
B
解析

试题分析:mustn’t禁止,一定不;needn’t不必;wouldn’t不会;shouldn’t不应该。must的含义是必须一定,其否定形式mustn’t表示禁止的含义。故must的否定回答一般借助于needn’和don’t have to来构成,句意:我们必须在八点前到达机场吗?——不,你不必。飞机在十二点起飞。结合语境可知选B。
点评:must的否定形式是常考内容之一,结构比较固定,熟记即可。
