关系代词在定语从句中充当主语的是: who, that, which, as宾语的是: who, whom, that, which, as定语的是: whose, which先行词是人时,关系代词是:who, whom, that, as先行词是物时,关系代词是:which, that, whose, as关系副词有:when (先行词为时间), where (先行词为地点), why (先行词为原因)关系副词 = 介词 + which / whom定语从句分为两种:限制性与非限制性。

先行词与关系词之间无逗号隔开为限制性;有逗号隔开则为非限制性,且一般由which引导。

唯一可以置于先行词之前的定语从句由关系代词as 引导。

二、关系代词引导的定语从句1.who指人,在从句中做主语(1) The boys who are playing football are from Class One.(2) Yesterday I helped an old man who lost his way.2. whom指人,在定语从句中充当宾语,常可省略。

定语从句详解(很全)

定语从句详解(很全)

定语从句定语从句(Attributive Clauses)在句中做定语,修饰一个名词或代词,有时也可以修饰部分或整个句子。

被修饰的名词,词组或代词即先行词。

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。

关系代词有:who,whom,whose,that,which,as。

关系副词有:when,where,why,how。

关系代词和关系副词放在先行词和定语从句之间,起连接作用,同时又可做定语从句的一个成分。

当关系代词做宾语时可以省略。

定语从句中的谓语动词必须在人称上和数量上和先行词保持一致。

定语从句分为限制性定语从句和非限制性定语从句。

一、定语从句的翻译许多英语初学者往往弄不明白为什么引导定语从句的关系词which不能译为“哪一个”,who不能译为“谁”,when不能译为“什么时候”,where不能译为“什么地方”,等等。

首先,我们必须要明白一点,那就是引导定语从句的which,who,when,where,why等是关系词(关系代词或关系副词),而不是疑问词,所以不能按疑问词的意思来理解。

前面我们讲到,英语中的定语从句总是后置的,即要放在被修饰名词或代词之后;但在汉语中,定语通常是前置的,也就是说定语要放在被修饰名词的前面,并通常表现为“……的”这样的形式。

当我们翻译英语中定语从句的时候,一般可以按汉语习惯,将定语从句翻译在被修饰的名词或代词之前,而其中的关系词一般就是译成汉语中的“……的”。

如:He showed me the article that he had written.他把他写的文章拿给我看。

句中的that he had written为修饰名词the article的定语从句,翻译时就可译为“他写的文章”,其中的关系代词that在此译成了“的”字。

She was not in the train which arrived just now.她不在刚到的那列火车上。

关系代词who 指人whom 指人whose 指人或物which 指物that 指人、物或事3、定语从句的构成(1)定语从句通常由关系代词在定语从句中引出关系,并在从句中担任某一成份的角色;(2)定语从句的谓语动词也可由一些连接词(link verb)连接,如be, feel, look, seem, smell, taste, remain,常用于定语从句中;(3)定语从句中如果省略结构,就不能用who/whom来引导定语从句;(4)定语从句中由关系副词引导而不是关系代词。

eg She is the girl(who got the first prize.)girl先行词who充当从句主语, 从句做定语修饰girlThis is the boy who broke the window.这就是打破窗子的孩子。

the boy是先行词, who broke the window是限制性定语从句, 明确指出theboy是打破窗子的那个孩子,who 在从句中充当主语That is the house where he lived ten years ago.He is the man who/that lives next door.He is the man who I want to see.先行词关系词定语从句复合句: 是由一个主句和一个或一个以上的从句构成的句子, 复合句中的主句和从句都具有完整的的主语和谓语, 主句是复合句的主体, 可以独立存在, 从句需要有一个连词引导, 是修饰说明主句的, 不能独立存在, 根据在句中的不同作用, 从句可以分为三类: 定语从句, 名词性从句, 状语从句。

二. 引导定语从句的关系词有两大类:1.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。

定语从句(完整版)

定语从句(完整版)

定语从句(完整版)定语从句是用关系代词或关系副词引导的从句,它的作用是修饰主句中的名词性成分,相当于形容词。

关系词包括关系代词和关系副词,常用的关系代词有that、which、who、whom、whose、as等,而关系副词则有where、when、why等。

关系词有三个作用,即引导定语从句、代替先行词、在定语从句中担当一个成分。

需要注意的是,关系代词有主语和宾语之分,其中whom通常作为宾语。

定语是用来限定、修饰名词或代词的,它可以由形容词、名词、代词、数词、分词、副词、不定式以及介词短语来担任,甚至可以由一个句子来担任。

在汉语中,我们通常用“……的”表示定语。

单词作定语时通常放在它所修饰的词之前,作前置定语;而短语和从句作定语时则放在所修饰的词之后,作后置定语。

被定语从句修饰的名词或代词称为先行词。

限定性定语从句有两种形式,一种是由关系代词引导的,另一种是由关系副词引导的。

关系代词that既可代表事物也可代表人,which则只能代表事物。

在从句中,that和which可以作主语或宾语,而that在从句中作宾语时常常可以省略关系词。

如果which在从句中作“不及物动词+介词”的介词的宾语,注意介词不要丢掉,而且介词总是放在关系代词which的前面,但有些例外。

需要注意的是,代表物时多用which,但在带有特定词语的句子中,如anything、everything、nothing、none等不定代词时,或者是由every、any、all、some、no、little、few、much等修饰时,应该使用that而不是which。

此外,当先行词前有序数词或形容词最高级修饰时,或先行词就是序数词或最高级时,或者先行词中既有人又有物时,也应该使用that,而不是which。

4.Who and whom are used to introduce clauses that modify people。

serving as the subject and object of the clause respectively。

当先行词与关系词之间没有逗号隔开时,就是限制性定语从句;而当先行词与关系词之间有逗号隔开时,就是非限制性定语从句,而且一般由which引导。

唯一可以置于先行词之前的定语从句由关系代词as引导。

关系代词who指人,在定语从句中充当主语;而whom 指人,在定语从句中充当宾语,常常可以省略。

关系代词which指物,在定语从句中可以充当主语或宾语,而它在充当宾语时可以省略。

需要注意的是,口语和非正式语体中,关系代词whom常常可以用who代替,并且可以省略。

XXX.This is the pen he XXX.When referring to a person。

"that" can be used in place of "who" or "whom" in object clauses。

and can be omitted.The number of visitors to the city increases by one n each year.Where is the man I saw this morning?XXX used to refer to people。
