Question

My father has many books , some of _____ are on history

I have many books, some of ____ are on chemistry.
A.them B that C. which D.those
选哪个？为什么？
为什么选择C .还不不懂。后面不是一个独立的句子吗？
麻烦具体分析一下句子结构。

Answer 1

为您解答如下：

C. which 为正确选项。

知识点延伸----------
1，some前面是个逗号，且没有连词，说明后半部分不是独立的分句，必须是修饰成分。填which，构成定语从句，修饰books。
2，some前面的逗号如果改为句号，则后半部分是个独立的句子，后半部分不是修饰成分。此时选A,them，同时some的首字母用大写S。
3，some前面加连词and，则也选A，them.此时，前后两部分构成并列句，不是修饰关系。
4，下列句子均为正确表达，意思一样，但表达方式不同。请楼主好好领会：
（1）My father has many books ，some of which are on history。
（2）My father has many books。Some of them are on history。
（3）My father has many books，and some of them are on history。
5，英语中的标点符号（尤其是逗号和句号）相当重要，它们决定着前后两部分是相互独立还是修饰与被修饰关系。

祝你进步！

Answer 2

你好：为你提供精确解答

此题【C】
因为，介词of 后面不能跟that，in that除外。
which是后面的非限制性定语从句的引导词。
翻译为：我爸爸有许多书，其中一些是有关历史的。

其实，some of 去掉就更容易看了，是典型的非限制性定语从句。
My father has many books , which are on history。

谢谢，不懂可追问~~

Answer 3

由于是逗号，故非独立句子。可改成：
I have many books. Some of them are on chemistry.或I have many books and some of them are on chemistry
My father has many books .Some of them are on history.或：My father has many books and some of them are on history.
原句为定语从句，介词后面不得用that。

Answer 4

which在此处是作为主语，修饰books,后面的句子不是独立句子，
