定语从句怎么判断先行词怎么划分从句

Question

如题所述

Answer 1

一、什么是定语从句？
用作定语的从句叫做定语从句(attributive clause)。定语从句通常皆置于它所修饰的名词(或代词)之后，这种名词(或代词)叫做先行词(antecedent)。引导宾语从句的关联词为关系代词和关系副词。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只用作状语。如：
The student who answered the question was John. 回答问题的那个学生是约翰。(who answered the question是关系代词who引导的定语从句，用以修饰who先行词student，who在从句中用作主语)
I know the reason why he was so angry. 我知道他这么生气的原由。(why he was so angry是关系副词引导的定语从句，用以修饰why的先行词reason，why在从句中用作原因状语)
二、定语从句的位置。
定语从句一般紧跟其先行词之后。如：
The room which served for studio was bare and dusty. 这个用作工作室的房间空荡荡的，布满灰尘。(关系代词which引导的定语从句紧跟其先行词room之后)
有时亦可与先行词分离。如：
A new master will come tomorrow who will teach you German. 明天要来一位新教师教你们德语了。(关系代词who引导的定语从句与其先行词master分离)

Answer 2

先行词是名词或代词,如果名词或代词后面有修饰它们的句子且它们在句中充当某一成分,它们就是先行词.
把先行词还原到从句中,就能判断做什么成份.
如:I will never forget the day when I first went to school.(先行词是day)
从句=I first went to school on the day.
(on the day 在从句中作状语=when)

I will never forget the day that was very special to me.(先行词是day)
从句=The day was very special to me
(the day 在从句中作主语=that/which)
