Question

The traffic administration indicates that airline passengers are only allowed to carry their luggage _______ less than 5 kilograms with them.

A．weighed	B．being weighed
C．weighing	D．to weigh

Answer 1

C

试题分析：句意：交通管理表明坐飞机的乘客仅仅被允许携带他们的行李的重量不超过5千克。to weigh表将来，或目的，显然不符合这里的语境。这里luggage与weigh之间是主动关系，故选C。
点评：本题难度适中。非谓语动词是高中阶段的重难点之一，内容多又杂，不容易理解，需要考生有分析理解复杂的句子结构的能力。题目的设置注重了情景化和结构复杂化，加大了考生对题干句的理解难度。设问的角度呈现出多样化趋势，不仅仅是非谓语间的互相干扰。
即学即练：Mother was surprised at the news of his son ____ to college．
A． had been admitted　　　 B． admitted
C． having been admitted　　　D． having admitted
解析：C。句意：消息表达的应该是个事件，说明不是“被录取的孩子”，介词of后不可能接从句，说明of后为动名词的复合结构，答案是C。
