解放军文职考试：引导限制性定语从句时并作从句宾语

引导限制性定语从句时并作从句宾语的关系代词whom可以用who来代替;但在非限制性定语从句中，whom就不能用who替换。

　　例6. Do you know Tom, _____ we talked about?

　　A. which B. that C. whom D. who

　　例7.The American journalist ______ the announcer mentioned in the news broadcast is said to have been killed by the gangsters. Which of the following is wrong?

　　A. who B. whom C. whose D. /

　　解析： 例6意为：“你认识汤姆吗? 我们谈到过他。”应选C。例7意为：“播音员在新闻广播中提到的那位美国记者据说已遭歹徒杀害。下列哪一项是错误的?”关系代词作mentioned的宾语且指人时，可用who/whom/that，在限制性定语从句中可省略，故C是错的。
