【定语从句】
一.概念
在复合句中,修饰某一名词或代词的从句,称为定语从句,也叫形容词性从句
二.相关知识点精讲
1.关系代词引导的定语从句
关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。
1）who, whom, that
这些词代替的先行词是人的名词或代词，在从句中作主语和宾语。例如：
Is he the man who/that wants to see you?（who/that在从句中作主语）
He is the man whom/ that I saw yesterday.（whom/that在从句中作宾语）
2） whose 用来指人或物，（只用作定语, 若指物，它还可以同of which互换）。例如：
They rushed over to help the man whose car had broken down.
限制性从句 Please pass me the book whose （of which） cover is green.
3）which, that所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等。例如：
A prosperity which / that had never been seen before appears in the countryside.
（which / that在句中作宾语）
The package （which / that）you are carrying is about to come unwrapped.
（which / that在句中作宾语）
2.关系副词引导的定语从句
关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。
1）关系副词when, where, why的含义相当于"介词+ which"结构，因此常常和"介词+ which"结构交替使用。例如：
There are occasions when （on which） one must yield.
Beijing is the place where（in which） I was born.
Is this the reason why （for which） he refused our offer?
介词﹢关系代词引导的定语从句,关键是判断介词的选择,方法一是看从句谓语部分缺少什么介词(习惯搭配),再则可以通过整个句子整体含义来判断,结合生活实际来判断.

2) 关系代词 whom， which 在定语从句中作介词宾语时，可以和介词一起放于先行词与定语从句之间，有时为了关系紧凑也可以将 whom 与 which 与先行词紧挨着书写，而将介词置于定语从句的后面，如：
That was the room in which we had lived for ten years.
= That was the room which we had lived in for ten years.
3. 具体使用时还要注意下列问题：
1）. 只能使用that,不用which 的情况：
(1) 先行词是no, much, all, few, little, nothing, everything, anything, something 等不定代词时。例如：
All that he said is true.
Is there anything (that) I can do for you ?
(2) 先行词被不定代词修饰时。例如：
He is the only foreigner that has been to that place.
You will receive no other answers that are better than mine .
(3) 先行词是序数词或被序数词修饰的词。例如：
He was the second (person) that told me the secret.
This is the last thing one can say about it.
(4) 先行词是形容词最高级或被形容词最高级修饰的词。
This is the best book (that) I have read this year.
(5) 先行词既包括人又包括物时。例如：
