知识点解读
之前我们分别学习了that和which的用法。因为that、which的辨析是定语从句的高频考点，所以今天我们做个了断，总结对比两者的区别，扒一扒其中的常考陷阱。
一、划重点——that/which辨析：
1.只能用that的情况：人物、高、序、不、避、恰
1). 人物：先行词既有人又有物时；
They talked about persons and things that they met.
2). 高：先行词被形容词最高级修饰时；
This is the most interesting film that I have ever seen.
3). 序：先行词被序数词修饰时；
He is the last man that I want to see.
4). 不: 先行词被不确定的数量词修饰（any, every, each, few, little, no, some, all等），或者先行词是不定代词（all, something, nothing, anything等）；
Is there anything that you want to buy in the shop？
5). 避：当句中已经有who或which时，为避免重复，只能用that；
Who is the girl that is crying？
6). 恰：先行词被the only, the very, the same(正是、恰恰是)修饰时。
This is the only bike that I lost.
2. 只能用which的情况：介词后面，逗号后面
1). 介词后面，指物的关系代词只能用which；
The house in which we live is very old.
2). 逗号后面，指物的关系代词只能用which。
I live in Beijing, which is the capital of China.
二、划重点-——常考陷阱：
1. that：高、序、不、恰
The biggest cat that I have is this one. (高)
This is the first book that I bought myself. (序)
He answered a few questions that the teacher asked. (不)
2. which：介词、逗号后面 ！！！
I saw a desk on which there was a book. (介)
Life is a flower of which love is the honey. (介)
I want to buy this book, which is very popular now. (逗)
