Eg.: You should hand in all that you have.

3.）先行词前面有the only, the very, the last, any, few, little, no, all, much, every等修饰时。

Eg.：The only thing that we can do is to give you some money.

4.）先行词既有人又有物时。

Eg. Do you know the things and persons that they are talking about?

5.）主句已有疑问词who 或which时。

Eg. Who is the woman that was praised at the meeting?

6.）当先行词在主句中作表语而关系代词也在从句中作表语时

Shanghai is no longer the city that it used to be.

He is not the man that he once was.

2.只用which不用that的情况

(1) 关系代词在限制性定语从句中紧跟介词作宾语（介词提前）。

This is the ring __________ she spent 1000 dollars.

(2)在非限制性定语从句中。

非限定性定语从句：特征:在先行词与定语从句间用逗号隔开，起补充说明作用，译成两句话．

Eg. He will go to see his wife, who is in Beijing。他将去北京看望妻子，她在北京工作．

Football, ______ is a very popular game, is played all over the world.

★ He failed in the exam, ______made her mother angry.

注意：（which 可以代替一个完整的句子，意思是"这样，这一点。"常放于句子中间）。

3.只用who 不用 that 的情况：

当先行词是anyone, those, he, she，one，ones等代词表"人"时，一般用who而不用that

Eg. God helps those who help themselves.
