怎么用先行词转换句子
定语从句在句中作定语用，修饰句中的某些名词或代词。被定语从句修饰的词叫先行词，先行词一般为人、物或事件。定语从句一般皆放在先行词之后。引导定语从句的关联词为关系代词或关系副词。关系代词在定语从句中可用作主语、宾语、定语等；关系副词在定语从句中作状语。本章要求掌握重点是定语从句的用法，及正确使用定语从句的关系代词和关系副词。
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.
二、物殊情况：
尽管有以上基本原则，但要学好定语从句更应注意以下特殊情况；
Ⅰ、当定语从句的先行词为表示人的不定代词，如 anyone,anybody,everyone,everybody,noone,nobody,all， these ，those等时,用who而不用that
Those who break the rule are pulished.
Anybody who had eyes could see the elephant was like a snake.
Ⅱ.以who或which作主语的特殊疑问句中先行词指人，引导词只用That,如:
a.Who is the person that is standing at the gate ?
b.Which of you that knows something about English doesn’t know this word?
Ⅲ、先行词指物时引导词用that而不用which的情况:
1、先行词有序数词或形容词最高级修饰时，
This is the best composition that has been written in English.
2、先行词是all,something,anything,nothing,everything,little,few,much等不定代词时
There is nothing/little/much that we can do for her.
3、先行词被all,every,no,some,any,little,much等修饰时

4、先行词被the only/very等修饰时

6、先行词为基数时

Ⅳ.time为先行词时，前边如有序数词修饰时，定语从句引导词用that或什么也不用，如没序数词修饰时，用when或that均可
a.This is the last time(that)I shall give you a lesson.
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.

这个句子先行词是哪个
这个句子中，主句是逗号前面的那句，在主句中，We是主语，should take是谓语，China craze是宾语，定语从句装饰的肯定是宾语。逗号加which是表示非限制性的定语。by及后面的词只是作为状语修饰宾语，它不是先行词。
先行词怎样造句
The man you saw on the bus is my uncle.这是一个定语从句，要想搞清楚哪个句子放在哪个地方，最重要的是分清哪个是主句，然后找到需要修饰的词，用关系代词连接修饰它的句子就可以了。至于关系代词还是关系副词，要看先行词在定语从句中的位置是什么。
怎么判断先行词在句子中的成分
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
