【先行词是什么】英语中的“先行词”是什么?

【答案】 先行词:是在定语从句中,被定语从句所修饰的名词.例如:
　　He is a teacher who teach our English.在这里定词从句who teach our English是来修饰前面的名词teacher.所以teacher就是一个先行词.
　　再说下它的用法：
　　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.
