请问定语从句引导词that和which的区别

看到网上有许多这种类别的解释，大多都不是很全面，有些又太深奥了或太长了，所以自己整理了一些精要的内容，希望能帮到你！
which能引导非限制性定语从句，而that不能；非限制性定语从句中即使缺宾语，引导词也不能省略；
先行词是物时，其引导词可用 which也可用that，通常情况下二者可互换，但在有些情况下不能。
1．用which不用that引导定语从句的三种情况：
①非限制性定语从句用which，不用that引导。如：
Football，which is a very interesting game，is played all over the world．
②先行词为that时，为了避免重 复，定语从句用which不用that引导。如：
That which you borrowed from me wasn't a real diamond necklace．
③介词后用which不用that引导。如：
The method with which you solved the problem is very good．
2．用that不用which的七种情况：
①先行词前有形容词*或序数词修饰时，用 that不用which引导。如：
This is the best place that I have ever visited．
The second question that is asked is why we don't fall off the earth．
②先行词为little，much，all，none，few，（the）one， something，everything，nothing，anything等不定代词时，用that引导。如：
There is nothing in the world that can frighten him．
③先行词既有指人的名词又有指物的名词时，用 that引导。如：
He told us about the people and the cities that he had visited．
④先行词前有any，all，no，few，every，some，little， much，（the）very，（the）only，（the）last等词修饰时，用 that引导。如：
This is the very coat that I need．
Is oxygen the only gas that helps fire burn？
⑤先行词为which时，为了避免重复，用that引导。如：
Which is the book that you bought yesterday？
⑥先行词在从句中作表语时，常用that引导。如：
Shanghai is no longer the city that it used to be in the 1930's．
⑦当主句是There be．．．句型时，用that引导。
There are two tickets for the film that are for you two．

从句中that做宾语可以省略

首先,that可指人和物,which则一般指物.,在限定性定语从句中两者的区别不大,但在非限定性定语从句中有以下区别：一、以下情况不能用that,只能用which：1、在非限定性定语从句中,逗号之后不能用that；2、介词后面不能...

1，当先行词既有人又有物的时候，只能用that; 2，特殊的先行词（1），,都可以指物，其用法区别： 1）不用that的情况 a) 在引导非限定性定语从句
