(3)除了上述所举的名词、代词、数词外，some, all, none, several, few等词都可接of+ which/ whom的句型。
限制性和非限制性定语从句的区别
区别：
1)在形式上
限制性定语从句的关系词和先行词之间不用逗号分开。
非限制性定语从句中两者则用逗号分开。
Jack is the kind of people who prefers listening to talking. (限定性)
杰克是那种宁愿聆听，不愿讲话的人。
The students, some of whom were rather busy, did not spend much time on music. （非限定性）
这些学生在音乐上花的时间不多，他们中有些人的确很忙。
2)在意义上
限制性定语从句说明的是句中的先行词必不可少的情况，它用来限制先行词所指的范围，其内容与先行词关系密切；若去掉此定语从句，剩下的部分则含义不明确、意义不完整或意义完全改变。
非限制性定语从句则与先行词关系较松散，只是对先行词做进一步的解释、补充或说明；若去掉此定语从句，整个句子意义一样很明确，不会引起误解和歧义。请看以下例句：
Beijing，which Is the capital of China，has developed into an international city．
3)在翻译上
限制性定语从句一般是直接将定语从句译成先行词的定语成分，如：“……的+先行词”；
非限制性定请从句一般则不宜译成先行词的定语成分，其译法相当灵活。常可译成状语从句，来表示原因、目的、结果、条件、让步等意义。我们比较以下例句：
The cab drivers who knew abut the traffic jam took another road. 知道那里塞车的出租车司机换了另一条道。（言外之意：不知道的司机则没有换路线，只有部分司机换路线了）
The cab drivers，who knew about the traffic Jam，took another load．出租车司机因为知道那里塞车了，他们都换了另一条道。（言外之意：所有司机都知道，都换了行驶路线）
4)在口语中
一般来说，限制性定语从句做停顿，非限制性定语从内要稍加停顿。
注意
（1）在非限定性定语从句中不能用关系代词that，其他的关系代词或关系副词根据情况进行选择，
(2)在非限定性定语从句中，无论关系词作什么成分都不要省略，如：
The mail .whom you met with just now is our English teacher. 你刚才碰到的那个人是我们的英语老师，在这个句子中whom是介词with的宾语，但却不能省略，
4)注意as和which引导的非限定性定语从句的不同，as引导的定语从句可以放在主句之前，也可放在主句之后，which只能放在主句之后，放在句末时，which译成：“这一点”、“这件事”怎么样？as往往译成“正像”、“正如”，如：

He came back on time，as we expected. 他按时回来了，正如大家所希望的。
例题：
The weather turned out to be very good, _____was more than we could expect.
A. What B. which C. that D. it
分析：A项what不引导定语从句，D项it不能体现两个分句的逻辑关系C项that不引导非限限制性定语从句。此题答案为B项。
练习：
1．His stories, ______this is one example, are all well written.
A. which B. for which C. of which D. that
2．He bought a lot of books, one of _____a few days before.
A. that was published B. which were published
C. which had come out D. that had been published
