Question

一道英语题，要解析

IS this book( )you want to borrow from the library?
A.that B.which
C.As D.\

Answer 1

B
book是可数名词单数，前面必须有定冠词。所以this是修饰book的
那么这句话换成陈述句就是this book is （ ）you want to borrow from the library.
我觉的最好应该填the one ,但是没有，所以应该就填which，吧，指代this book，you want to borrow from the library是定语从句，省略了that。

Answer 2

选项似乎有问题，个人觉得应填the one 才对。

Answer 3

选B 定语从句
还原成陈述句你就能看明白了
This book is （the one） you want to borrow from the library the one 在这里等于which
填THAT ,AS 或不填这个句子都缺成分，

Answer 4

B
