Of the 9,500 drivers ____ since the beginning of the year, 23% were found ____ in road knowledge.

A．tested; lacked	B．testing; lacked
C．tested; lacking	D．to test; lacking

Answer 1

C

解析试题分析：考查非谓语动词：句意：在今年年初以来被检测的9500个司机中，23%被发现缺乏公路知识。第一空做后置定语，修饰drivers，因为drivers和test是被动关系，用过去分词做定语，第二空是主语补足语，主语是the drivers和lack是主动关系，用现在分词做补足语，选C。
