The young man____ is a friend of mine. A. who I had a talk B. whom I had a talk with

C. whom I had a talk D. which I had a talk with

B
whom表示宾语

have a talk with sb 与...谈话

b 试题分析：本句中先行词young man为下文从句的逻辑宾语，talk 不能直接接宾语。talk with和……谈话。英语中指人的引导词做介词宾语时，需要用宾格形式whom，故选b。 点评：定语从句引导词的用法比较复杂,其关键就是根据先行词的不同选择不同的引导词.并注意作介词宾语的引导词只能使用宾格形式.that不能用于非限制性定语从句中.
