定语从句 引导词如何使用?

Answer 1

引导定语从句的关联词称为关系词,关系词有关系代词和关系副词.关系代词有that, which, who, whom, whose, as等；关系副词有where, when, why等.关系词常有3个作用：1,引导定语从句.2,代替先行词.3,在定语从句中担当一个成分.
关系副词引导的定语从句
1. when指时间,在定语从句中做时间状语
(1) I still remember the day when I first came to the school.
(2) The time when we got together finally came.
2. where指地点,在定语从句中做地点状语
(1) Shanghai is the city where I was born.
(2) The house where I lived ten years ago has been pulled down.
3. why指原因,在定语从句中做原因状语
(1) Please tell me the reason why you missed the plane.
(2) I don’t know the reason why he looks unhappy today.
注意：关系副词引导的从句可以由“介词+关系代词”引导的从句替换
(1) The reason why/ for which he refused the invitation is not clear,
(2) From the year when/in which he was going to school he began to know what he wanted when he grew up.
(3) Great changes have taken place in the city in which./where I was born.
[编辑本段]（六）判断关系代词与关系副词
方法一： 用关系代词,还是关系副词完全取决于从句中的谓语动词.不及物动词后面无宾语,就必须要求用关系副词或者是介词加关系代词；而及物动词后接宾语,则要求用关系代词.例如：
This is the mountain village where I stayed last year.
I'll never forget the days when I worked together with you.
判断改错（注：先显示题,再显示答案,横线；用不同的颜色表示出.）
（错） This is the mountain village where I visited last year.
（错） I will never forget the days when I spent in the countryside.
（对） This is the mountain village (which) I visited last year.
（对） I'll never forget the days (which) I spent in the countryside.
习惯上总把表地点或时间的名词与关系副词 where, when联系在一起.此两题错在关系词的误用上.
方法二： 准确判断先行词在定语从句中的成分(主、谓、宾、定、状),也能正确选择出关系代词/关系副词.例1. Is this museum ___ you visited a few days ago?
A. where B. that C. on which D. the one
例2. Is this the museum ____ the exhibition was held?
A. where B. that C. on which D. the one答案：
例1 D,例2 A
例1变为肯定句： This museum is ___ you visited a few days ago.例2变为肯定句： This is the museum ___ the exhibition was held.
在句1中,所缺部分为宾语,而where, that, on which都不能起到宾语的作用,只有the one既做了主句的表语,又可做从句的宾语,可以省略关系代词,所以应选D.
而句2中, 主、谓、宾俱全,从句部分为句子的状语表地点,既可用副词where,又因 in the museum词组,可用介词in + which 引导地点状语.而此题中,介词on 用的不对,所以选A.
关系词的选择依据在从句中所做的成分,先行词在从句中做主、定、宾语时,选择关系代词 (who, whom, that, which, whose)；
先行词在从句中做状语时,应选择关系副词 ( where 地点状语,when 时间状语,why 原因状语) .
由as, which 引导的非限定性定语从句,as和which可代整个主句,相当于and this或and that.As一般http://baike.baidu.com/view/56536.html?wtp=tt放在句首,which在句中.
