划分一下句子结构.

答：带定语从句的复合句,实际上由两个简单句复合而来：
The man is a reporter from the newspaper.那人是个报社记者.
My father is talking with him.(him是人称代词,就是指前句中的the man) ：我父亲正与他交谈.
或My father is talking to him.我父亲正与他谈话.
--》The man 【with whom my father is talking】 is a reporter from the newspaper.
【我父亲正与之交谈的】那人是个报社记者.
--》The man 【to whom my father is talking】 is a reporter from the newspaper.
【我父亲正与其谈话的】那人是个报社记者.
析：原句有误.
