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

這題考查現(xiàn)在分詞做定語的用法：可以看and前后并列，前面under the age of 4做young children 定語，后邊也應該是做young children 定語。Weigh做為“重達”講，是不及物動詞，不用被動，用現(xiàn)在分詞做定語，句意是：交通法規(guī)規(guī)定：4歲以下并且少于40磅的小孩必須坐在兒童安全坐位上。
