People who drink wine to drive after May Day.

A. don’t allow

B. isn’t allowed

C. mustn’t allow

D. mustn’t be allowed

答案：

A. don’t allow

B. isn’t allowed

C. mustn’t allow

(答案→)D. mustn’t be allowed

解析：本题考查be allowed to do sth.的否定形式。be allowed to do sth.意为“同意，许可做某事”。其否定形式为mustn’t be allowed to do sth.意为“不允许”。句意“五一以后喝酒的人禁止开车”。故选D。
