1、一、英语中的定语从句与汉语中的定语位置不同。在复合句中,修饰某一名词或代词的从句叫做定语从句。英语中的定语从句始终要放在被修饰的词之后,而汉语中的定语则放在被修饰词之前。如:The man(先行词)who / that I saw at the school gate yesterday(定语从句) is my English teacher.昨天我在校门口看见的那个人是我的英语老师。二、英语从句中的句型结构比较复杂,有先行词、关系代词或关系副词。被定语从句修饰的词叫先行词,引导定语从句的关联词有关系代词或关系副词。限制性关系分句和它的先行项的所指意义有着不可分割的联系。关系代词或关系副词放在
2、先行词和定语从句之间起纽带作用,关系代词或关系副词在定语从句中要充当一个成分。关系代词在句中可作主语、宾语或定语,关系副词在句中作状语。如:I am waiting forthe boy(先行词)who /that(关系代词)is wearing a red coat. (主语)我正在等穿着红色外套的那个男孩。The dictionary(先行词)that / which(关系代词) my sister gave me last Sunday is very expensive.(宾语)我姐姐上周星期天给我的那本字典很贵。The woman ishis mother(先行词)whose(关系代
3、词) name is Linda Brown. (定语)那个是他的母亲,名叫琳达布朗。That isthe house(先行词)where(关系副词) my father used to live.(状语)那是我父亲曾经居住过的房子。三、初中英语中定语从句关系代词或关系副词的具体用法。1. who指人(也可用that),在定语从句中作主语,也可作宾语。如:Yesterday I helped an old manwho / thatlost his way. (主语)昨天我帮助了一位迷路的老人。Mr Wang is the man(who / that / whom)you met in th
4、e zoo this morning.(宾语)王先生就是今天早上你在动物里遇到的那个人。注意:关系代词who指人,作宾语时,可用whom代替;作宾语时,关系代词可省略。作其它成分,关系代词则不能省略。2. whose指人,也可指物。在定语从句中作定语。The boywhosemother is ill is staying at home to look after her today.他母亲生病的那个男孩今天呆在家里照顾她。I have a story bookwhosecover is red.我有一本封面是红色的故事书。3. which指物(也可用that),在定语从句中作主语,也可作宾
5、语。如:Football is a gamewhich / thatis liked by most boys. (主语)足球是被大多数男孩喜欢的运动。I dont believe the newswhich / thatTom won the game. (宾语)我不相信汤姆赢得这场比赛的消息。四、关系代词whom, which在定语从句中作介词宾语时,可以和介词一起放在先行词与定语从句之间。That is the placein whichI lived for five years.=That is the placewhich / thatI lived in for five yea
6、rs.那就是我住过五年的地方。Mr Zhang is the manfor whomI am looking.=Mr Zhang is the manwho / whom / thatI am looking for.张先生就是我正在找的那个人。五、具体使用关系代词或关系副词需要注意的问题。1. 先行词是地点时,如果该先行词做了定语从句的主语或宾语时,关系代词用that或which.如:The schoolthat / whichI used to study in is becoming better and better.(the school 作了介词in的宾语。)我过去曾经学习的那所学
7、校变得越来越好了。先行词是地点时,如果该先行词不作定语从句的主语或宾语时,关系代词用where.如:The placewherethe accident happened isnt far from our school.事故发生的那个地方离我们学校不远。(定语从句中的动词happened是不及物动词,它不跟宾语,而the accident又作了定语从句的主语,因此该定语从句既不需要主语,也不需要宾语。)2.只用that,不用which的情况。(1)前有序数词修饰时。如:This is the tenth giftthatI received for my birthday.这是我收到的第十个
8、生日礼物。(2)前有形容词最高级修饰时。如:That is the most exciting gamethatI have ever watched.那是我曾经看过最令人兴奋的比赛。(3)先行词是all, little, few, something, anything, everything等不定代词时。如:Allthathe told me is true. 他告诉我的一切是真实的。(4)先行词被the only修饰时。如:The only thingthatI can get is a pen. 我唯一能得到的东西就是一支钢笔。(5)先行词既指人,又指物时。如:We talked about the people and the thingsthatwe were interested in.我们谈论了我们感兴趣的人和事。3. 只用which,不用that的情况。(1)定语从句是物时,定语从句由“介词+关系代词which”引导。如:The thingabout whichthe teacher is talking is very important.老师正在谈论的那件事非常重要。(2)先行词本身是that, those时,如:Whats thatwhichis flying in the sky?在天空中飞的那是什么?
