如何正确使用定语从句中的关系代词
定语从句中的关系代词有that, which, who, whom, whose等。其中，who whom 可指人，which可指物，whose，that可代替人或物。我们都知道关系代词在句中主要是代替先行词是人或物的名词或代词，表达该先行词的意思，有着主语，宾语，定语的作用。

A.Fortunately，I eventually live in a house whose(of which) rent is lower.幸运的是，我最终住在了一个费用较低的房子里。
B. The old man whose son is an excellent artist is kind.这个热心老人的儿子是个杰出的艺术家。
3.在从句中作宾语，其中关系代词前有介词时,指人用whom
A.She is the star with whom you have talked is the one I admire.你所谈论的她就是这个我所崇拜的明星。（不可用that）
B.This is the watch which he found at the shop yesterday.这是他昨天在商店找到的表。
C.Can you tell me where is the man that I saw from the picture?你能告诉我从图片上看到的这个人在哪吗？
