Question

is this book that（which）you borrowed from library

is this book that（which）you borrowed from library是用which 还是that 为什么

Answer 1

该题考察定语从句。
先行词为this book。that和which为从句引导词，此处为关系代词。
当先行词为物时，that和which均可使用。
当先行词为人时，需用who（在从句做主语、宾语），whom（在从句做宾语）。

ps:
1,必用that或which情况例外。
2,非限制性定语从句用which。

Answer 2

which 在从句中作宾语，而且which是特指的这本书。所以要用which。

Answer 3

都行，这两个在定语从句都可做宾语，但which只能指物，that既可指人也可指物

Answer 4

都可以.

追答

因为先行词是物

如果把介词from 提到前面只能用which
即
Is this book （which）you borrowed from library

后面一次发错

from 不能提前

因为先行词book 是物，这里的引导词用that /which 都可以
