定语从句21大核心考点（十一）定语从句(Attributive Clauses)定语从句（Attributive Clauses）定义：在句中做定语，修饰一个名词或代词，被修饰的名词,词组或代词即先行词(antecedent)。

定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。

关系词分类：由在从句中的地位划分上讲,引导词可分为三类:一．主语,宾语引导词．如: who , whom , that , which , as二 .定语引导词．如: whose三 .状语引导词．如: where , when , why（非常六加三，九个关系词）关系词的作用：一是引导从句;作为从句的重要标志.二是代替先行词, 被定语从句修饰的词称为先行词,先行词一般是名词和不定代词，如:some-, any-, every-和no与-boy,-thing的合成词；或all、none、any、some、that、those等代词。

数词也可以作先行词，人称代词也同样可作先行词; 三是在从句中充当成分,可充当主语、表语、宾语、定语、状语等。

关系词在从句子中充当了成分，其意思就是先行词的意义，所以在从句中不能重复其意。

Anyway, that evening, ____ I’ll tell you more about later, I ended up staying at Rachel’s place.（浙江卷04-35）A. whenB. whereC. whatD. which2. I shall never forget these years ____ I lived in the country with the farmers, ____ has a great effect on my life.(上海94)A. that; whichB. when; whichC. which; thatD. when; who (B)【透视】1.D 2.B【超链接】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。

及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。

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 age?A. whereB. thatC. on whichD. the one例2. Is this the museum ____ the exhibition was held.A. whereB. thatC. on whichD. 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) 。
