定语从句里whose 、of which、of whom 的用法

Question

whose在什么情况下可以被of which、of whom 所替换
of which、of whom 在定语从句中作什么成分，有什么固定的形式吗

Answer 1

whose、of which和of whom都是定语从句中的引导词
of which 指物，of whom 指人，而whose既可指物又可指人 。所以指物的时候，可以用whose也可以用of which 代替；指人的时候可以用whose，当然可以用of whom 代替。
其实whose、of which和of whom的使用比较特殊，成分不是简单地主语宾语表语等，而是这个语中的一个名词所属。（就成分而言，和常规的只用which， who，whom或that 略有区别，因为常规的which， who，whom或that 可以较明确的指明它们在从句中的成分。比如 this is the book which i bought yesterday. which 做从句的宾语）
而且写出来，多是非限定性定语从句，即加一个“，”。
of whom ：I knew Li Ming, whose uncle is a teacher.
I knew Li MIng, the uncle of whom is a teacher.
源自 两个简单句或一个并列句
I knew Li Ming. His uncle is a teacher.
I knew Li Ming and his uncle is a teacher.

of which I saw the montain, whose top was covered with snow.
I saw the mountain, the top of which was covered with snow.
同样源自 两个简单句或一个并列句
I saw the mountain. The top of mountain was covered with snow.
I saw the mountain. and the top of it was covered with snow.
或I saw the mountain. and its top was covered by snow.

Answer 2

1）whose有时可以与of which互换。但使用后者时，在of which所修饰的名词之前常加一个限定词：
The building whose roof we can see from here is a hotel.
The building the roof of which we can see from here is a hotel.
我们从这儿能看见房顶的那座建筑是一家旅馆。
I saw some trees whose leaves were black with disease.
I saw some trees the leaves of which were black with disease.
我看见一些因病叶子变黑了的树。
2）whose的意义与of whom近似，但whose表示所有关系，而of whom则表示范围（主要用于非限制性定语从句，另见10.3~8）或其它意义：
The boys whose names were called stood up. 被叫到名字的几个男生站起来了。
I met the newcomers, several of whom were Chinese. 我见到了那些新来的人，他们中有几个是中国人。
Qi Dark, of whom you may have heard, is his sister. 齐大可，你可能听说过，是他的姐姐。
