Question

The traffic rule says young children under the age of four and ________ less than 40 pounds must be in a child safety seat.

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

Answer 1

D

此处weigh为“重量为；重(多少)”的意思，作young children的后置定语，且与其关系为主动，用weighing，故D项正确。句意为：交通规则规定四岁以下并且体重少于40磅的儿童必须放于儿童安全座椅上。
