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

考查分词做定语用法。因为children与weigh(重达…)构成主动关系，使用现在分词短语Weighing less than 40 pounds做定语修饰名词young children.句意：交通法说四岁以下和轻于40磅的儿童必须坐在儿童安全椅上。故D正确。
