Question

【题目】Passengers are permitted __________ only one piece of hand luggage onto the plane.

A. to carry

B. carrying

C. to be carried

D. being carried

Answer 1

【答案】A

【解析】句意：旅客只被允许带一件手提行李登机。本题考查非谓语动词作主语补足语。permit sb. to do sth. 允许某人做某事，其被动语态为：sb. be permitted to do sth. 某人被允许做某事，所以A项正确。注意permit的另一用法：permit doing sth. 允许做某事。
