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

这题考查现在分词做定语的用法：可以看and前后并列，前面under the age of 4做young children 定语，后边也应该是做young children 定语。Weigh做为“重达”讲，是不及物动词，不用被动，用现在分词做定语，句意是：交通法规规定：4岁以下并且少于40磅的小孩必须坐在儿童安全坐位上。
