Question

the book the cover of which is

The book,the cover ___ is broken,is not mine.
A of it B for C whose D of which
选D,为什么

Answer 1

这是定语从句常见的题,这种定语从句有三种表达方式
以上面的句子为例
第一种：The book,the cover of which is broken,is not mine.
第二种：The book,of which the cover is broken,is not mine.
第三种：The book,whose cover is broken,is not mine.
记住就好,至于为啥选D很简单,A和B中没引导词,不能接从句,Cwhose在定语从句中做定语,而且放在一个名词前,所以D
