Question

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

A. weighed     B. being weighed

C. weighing     D. to weigh

Answer 1

20.   C考査非谓语动词。此处their luggage和weigh之间是主动关系，所以用现在分词作定语。这里不是指具体的行李被称重，而是说明性质，即少于5公斤的行李，这时用主动形式表示被动含义。
