定语从句中是不是of后面只能加whom和which

是的，这是介词+关系代词的用法。

1,单个介词+关系代词(whom, which)

　　介词确定依据

a依从句中的动词,形容词,名词与介词的固定搭配而定

b依先行词与从句中动词的关系及所表达的含义而定

A harvester is a man who is harvesting or a machine with which we harvest crops.

2,复杂介词+关系代词(which, whom, whose) 常用复杂介词:as a result, at the back of ,because of, in front of, in the middle of, at the bottom of, on the top of, at the foot of 注意:但含有介词的短语动词一般不能拆开,如 look after, be made of, take part in, look forward to等。 例：The babies (who/whom) the nurses look after look strong and happy.

There is a great pain in my right foot, because of which I can only limp along.

定语从句中何时whose，何时用of whom/which

非限制型定语从句中用of whom/which

限制型定语从句中用whose

定语从句里whose 、of which、of whom 的用法

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.

非限制性定语从句中 基数词+of whom不能用of who 吗

不能噢，以为这里的who做了of的宾语，所以要用其宾语形式whom。
