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
题目解答
答案
D. weighing
解析
本题考查动词的现在分词形式作形容词用法。关键点在于理解句子结构中并列成分的修饰关系。题目中“under the age of four”和空格处的结构均作为形容词短语修饰主语“children”,需选择与“weigh”搭配的正确形式,体现主动、持续的状态。
选项分析
- A. being weighed:现在分词被动形式,表示被动动作,但此处需主动描述体重状态,排除。
- B. to weigh:不定式表示未发生动作或目的,与语境不符,排除。
- C. weighed:过去分词表示被动完成,但体重是持续属性,需主动形式,排除。
- D. weighing:现在分词作形容词,表示主动、持续的体重状态,符合语境。
关键结论
“weigh”在此作形容词,意为“体重达...”,需用现在分词形式weighing,与“under”构成并列的形容词短语修饰主语。
