在定语从句中怎样区别THAT,WHICH,WHERE的用法？

Question

回答尽量简洁、准确。

Answer 1

that和which在定语从句中只能作主语或宾语，而where在定语从句中只能作地点状语。

that和which的相同之处：
都可以作主语或宾语，都可以指代人或物。

that和which的区别：
that的三不用：
1、非限制性定语从句只能用which引导，不能用that引导。
2、紧跟在介词后面的关系代词不能是that。如：
Give me a pen with which I will write an essay.
3、关系代词后面有插入语时不能用that。如：
Here is the gramma book which, as I have told you, will help you improve your English.
比较：Here is the gramma book which/that will help you improve your English.
that的六必用：
1、先行词有形容词的最高级修饰，或有序数词修饰时，必用that。
2、在不定代词，如：anything, nothing, the one, all, much, few, any, little等作先行词时，只用that，不用which。
3、先行词既有人，又有物时，只用that，不用which。
4、在there be 句型中，只用that，不用which。
5、先行词有the only, the very修饰时，只用that。
6、 关系代词在从句中作表语并带有类比含义时， 通常只用that， 不用which.例如：
He is no longer the star that he was. 他不再是过去的那位明星了。

Answer 2

1、关系代词：(who, whom, whose, that,) 指人 which , as（指物 which whose of which that ）

2。 只能用 which 不能用 that 的情况。
>①、 引导非限定性定语从句修饰某物或整个句子。

>② 、关系代词作介词的宾语。This is the house in which Lu Xun once lived.
