(3) 主句中已有疑问词时

(5) 先行词是all,much,little,something,everything,anything,nothing,none,the one等代词时

定语从句的关系副词 Where的用法:若先行词指地点且其在定语从句中充当地点状语.
This is the house+I was born in the house.(=I was born there)
介词短语 副词
=This is the house where I was born.这就是我在那儿出生的房子.
先行词 关系副词
in which I was born.
介词+关系代词
which I was born in.
关系代词
这里作介宾的which和that可以省略
that I was born in
定语从句中的that和which用法区别that和which在从句里都可以做宾语和主语，做宾语时可以省略。在定语从句中,有种说法叫"关宾省"，意思是关系代词在限制性定语从句中作宾语可以省略，不管是that，which，还是whom。但是which能引导非限制性定语从句，that则不行。
其次，记得以下只能用that的几种情况：
1. 当先行词为all, much, little, none及由any, every, some, no所构成的复合不定代词时。
如：
Please tell me anything that you know about the matter.
有关此事，凡是你所知道的请告诉我。
2. 当先行词被any, few, little, no, all, much, some等词修饰时。
如：You can take any seat that is free.
任何空着的座位你都可以坐。
