先行词一共有哪些?

先行词是定语从句的引导词前面的名词.在定语从句中充当一定的成分.
被定语从句修饰的名词、代词称为先行词。
我们可以这样认为, 之所以称它为先行词, 是因为修饰它的定语从句总是放在它之后, 先行词总是出现在定语从句之前, 而不同于普通形容词修饰名词时, 形容词位于名词之前。
This is the book which I am looking for.中的book是先行词,which是引导词.
He is Mr. Robertson who comes from England. 中的Mr. Robertson.是先行词,who是引导词.
简单的说，就是和修饰宾语的词或从句，词就是先行词

1、先行词指人时，引导词可用Who,Whom,及that,其中当引导词在句中作主语时用Who或that；当其充当宾语时用whom或that，在非正式宾语中也可用who，也可省略。
a That boy who/that broke the window is called Tom.
b The person to whom you just talked is Mr Li.
b 句可改为：The person(that/whom/who)you just talked to is Mr Li.

2、先行词指物时，引导词用that或which
a.They planted the trees which didn’t need much water.
b .The fish (which)we bought were not fresh.

3、先行词指时间时，引导词用When/on which或in which
a.I still remember the day when/on which I first came to Bei jing.
b.I'll never forget the year when/ on which we worked on the farm.

4、先行词指地点时，引导词用Where或in which
This is the house where/in which we lived last year.
或:This is the house that/which we lived in last year.

5、whose在定语从句中作定语时，可用来指人，也可以用来指物，如:
a.This is the boy whose mother died a month ago.
b.This is the house whose windows were broken.此句可改成：
This is the house the windoues of which were broken.

6、先行词表示原因时，引导词用why,如:
The reason why he was late for school was that he had been knocked down by a bike.

你大概是概念没有弄清楚，先行词是被定语从句修饰的那个词，通常只有两种词性，名词或代词。如：
the book which is on the desk
the book 是先行词； which 是关系代词。

我想你大概要问的是 关系词。下面给你作个归纳。

关系词分为关系代词和关系副词。
先说关系代词。
修饰物的有: that which whose
修饰人的有 that who whom whose
还有特殊的 as, but(该词估计你上了大学英语专业会详细学到）

常见的关系副词有;
where when why that(特殊情况下也作副词，如用在 way 的后面）。
最后，祝你进步！

who , whom , whose, that, which , when , where, why, as

that,which,what,who,whom,whose,how,why
