is this book _____ you borrowed from the library the other day?这一题选什么?

Question

A that B one C whih D what
是不是选D啊？

Answer 1

答案是D
is（this book）_____ you borrowed from the library the other day?
首先要明白主语是this book，这不是定语从句，因为没有先行词，所以A,B,C都不对，
只有what在句中能做双重成分，它既做is的表语，又做从句中borrow的宾语。
这是what引导的名词性从句
如果句子是is this（the book）_____ you borrowed from the library the other day?的话，that和which都能用

Answer 2

选C
非限制性定语从句 从句中不缺乏成分
用which引导

Answer 3

把句子改为陈述句就好做了。
This book is _____ you borrowed from the library the other day.
当然选择one了。
句子主干是This book is one(book).
后面的部分是定语从句，用来修饰one（book）的。并且先行词one做了borrowed的宾语，引导词that省略。
