Question

Alec asked the policeman ________ he worked to contact him whenever there was an accident．

[　　]

A．with him

B．who

C．with whom

D．whom

Answer 1

答案：C
解析：

此题意思是“Alec要求和他一起共事的那位警察，无论什么时候出现事故都要和他联系”．此题考查关系代词在从句中的作用．to contact是与ask的不定式结构有关．此外，he worked在此作定语，其结构应是he worked with the policeman，故不能用D项．应选C．
