5、.定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般跟在它所修饰的先行词后面。在复合句中，修饰某一名词或代词叫做定语从句。 关系词 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，绝对没有what；关系副词有where, when, why等。关系词常有3个作用： 连接作用，引导定语从句。 代替主句中的先行词，甚至可能是主句中的一部分或者整个主句。 在定语从句中充当一句子成分。 一who, whom, that 这些词代替的先行词

6、是人的名词或代词，who做主语指人，whom作宾语指人，that既可作主语又可作宾语（作宾语可以省略），可以指人也可以指物。在从句中所起作用如下： (1) Is he the man who/that wants to see you? 他就是想见你的人吗？（who/that在从句中作主语） (2) He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。（whom/that在从句中作宾语）二代表物时多用which，但在下列情况中用that而不用which： a)先行词是anything, everything, nothing , none

7、等不定代词时； b)先行词由every, any, all, some, no, little, few, much等修饰时，这时的that常被省略； c)先行词前有序数词或被形容词最高级修饰时； d)先行词中既有人又有物时； e)整个句中前面已有which，who, that时； f)当先行词为物并作表语时； g)先行词为one时； h)先行词同时又被the only,the very,the same修饰时三非限制性定语从句非限制性定语从句的作用是对所修饰的成分作进一步说明，通常是引导词和先行词之间用逗号隔开，将从句拿掉后其他部分仍可成立 1. which引导的非限定性定语从句作用是说明前

8、面整个句子的情况或主句的某一部分 2.当先行词是专有名词、物主代词或指示代词所修饰时，其后的定语从句通常是非限制性的，例如： Charles Smith, who was my former teacher, retired last year. 查理史密斯去年退休了，他曾经是我的老师。 My house, which I bought last year, has got a lovely garden.我去年买的的那幢房子带着个漂亮的花园。 This novel, which I have read three times, is very touching. 这本小说很动人，我已经读了三

9、遍。 which指物 在定语从句中做主语，表语，定语或者宾语，做宾语时可省略。 (1) Football is a game which is liked by most boys. 足球是大多数男孩都喜欢的游戏. (2) This is the pen (which) he bought yesterday. 这是他昨天刚买的钢笔. that指人时,相当于who或者whom；指物时，相当于which。在定语从句中做主语,表语或者宾语，做宾语时可省略。 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

10、语，则要求用关系代词。 例如： This is the mountain village where I stayed last year. Ill 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

11、 the mountain village (which) I visited last year. （对） Ill 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。 例1. Is this museum _ you visited a few days ago? A. whereB. thatC. on whichD. the one 例2. Is this the museum _ the exhibition was he

12、ld? 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，is后应跟表语，只有the one可以，而后面的you visited a few days ago则做one的定语从句,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 + whic

13、h 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) 。1.
