定语从句讲解被修饰的词叫先行词。定语从句不同于单词作定语的情况,它需要放在被修饰的词(即先行词)之后。定语从句由关系词(关系代词、关系副词)引导,关系代词、关系副词位于定语从句句首。 关系代词引导的定语从句 关系代词所代替的先行词是人或物的名词或代词,并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时,从句谓语动词的人称和数要和先行词保持一致。1)who, whom, that这些词代替的先行词是人的名词或代词,在从句中所起作用如下: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)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)2) Whose 用来指人或物,(只用作定语, 若指物,它还可以同of which互换), 例如:They rushed over to help the man whose car had broken down. 那人车坏了,大家都跑过去帮忙。Please pass me the book whose (of which) cover is green. 请递给我那本绿皮的书。3)which, that它们所代替的先行词是事物的名词或代词,在从句中可作主语、宾语等,例如:A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。(which / that在句中作主语)The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了。(which / that在句中作宾语)关系副词引导的定语从句关系副词可代替的先行词是时间、地点或理由的名词,在从句中作状语。1)when, where, why关系副词when, where, why的含义相当于介词+ which结构,因此常常和介词+ which结构交替使用,例如:There are occasions when (on which) one must yield. 任何人都有不得不屈服的时候。Beijing is the place where (in which) I was born. 北京是我的出生地。Is this the reason why (for which) he refused our offer? 这就是他拒绝我们帮助他的理由吗?2)that代替关系副词that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和介词+ which引导的定语从句,在口语中that常被省略,例如:His father died the year (that / when / on which) he was born. 他父亲在他出生那年逝世了。He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住过的地方。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。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.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 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。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.2从句结构先行词指被定语从句修饰的名词、代词。一般先行词出现在定语从句的前面。关联词关联词常有2个作用:连接作用,引导定语从句。代替先行词,在定语从句中担当一个成分。注:关系代词有主语、宾语、定语之分。一般who做主语或其宾格形式的whom做宾语,whose作为定语(whom可省略,whose不可省略)。关系代词在从句中作主语,宾语,定语等,关系副词在从句中作地点状语(where)时间状语(when),原因状语(why)。定语定语用来限定、修饰名词或代词,是对名词或代词起修饰、限定作用的词、短语(动词不定式短语、动名词表示的)汉语中常用“的”表示。主要由形容词担任,此外,名词、代词、数词、分词、副词、不定式以及介词短语也可以来担任,也可以由一个句子来担任。单词作定语时通常放在它所修饰的词之前,作前置定语。短语、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、代词称为先行词。如“the girl”,“the book”如:She is the girl who likes singing. 她就是那个喜欢唱歌的女孩。这就是一个定语从句。3关系代词关系代词所代替的先行词是人或物的名词或代词,并在从句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时,从句谓语动词的人称和数要和先行词保持一致。1、who, whom, that限定性定语从句中的关系代词作主语作宾语作定语指人who/thatwhom/that(可省略)whose指物which/thatwhich/that(可省略)whose指人和物thatthatwhose非限定性定语从句中的关系代词作主语作宾语作定语指人whowhomwhose/of whom指物whichwhichwhose/of which特殊情况:只能用that的情况,先行词为everything,all,little,much等不定代词时;先行词被all,every,no,any,some,little,much,one修饰时;先行词被the only,the very,the same,the last修饰时;先行词被序数词或形容词最高级修饰时;先行词是be的表语或there be 的主语时;先行词有人又有物时;当主句是以who或which开头的特殊疑问句时。不能用that的情况介词前置时;非限定性定语从句中多用who,不用that的情况先行词为all,anyone,one,ones时;先行词为those,he和people时;这些词代替指人,whom在定语从句中指人,who和“that”既可作主语又可作宾语(作宾语可以省略,who作宾语变为whom),that可以指人也可以指物, who不可指物 。在从句中所起作用如下:(1)Is he the man who/that wants to see you? 他是那个想见你的男人吗?(who/that在从句中作主语)(2)He is the man (whom/that) I saw yesterday. 他就是我昨天见到的那个人。(whom/that在从句中作宾语)(3)The man whom you spoke to just now is our English teacher. 刚刚和你说话的那个男人是我们的英语老师。(whom在从句中作宾语)注:who在定语从句中指人,作主语和宾语,作宾语时可省略;做及物动词或介词的宾语,可省略。2,which,that 用来指物(有六种情况只可用that而不用which)(用作主语、宾语,作宾语时可以省略),例如:(1)The prosperity which/that had never appeared before took on in the countryside.农村出现了前所未有的繁荣。(which/that在从句中作主语)(2)The package (which/that) you are carrying is about to come unwrapped.你拿那个包裹快要散开了。(which/that在从句中作宾语)注:which在定语从句中指物,可作主语或及物动词或介词的宾语,作宾语时可省略;that在定语从句中既可指人又可指物,在定语从句中作主语、宾语和表语,作宾语时可省略,指人时,相当于who或whom,指物时,相当于which,作介词宾语时,介词不可提到that前,当介词提前时,需要用which或whom来代替。2、whose(只用作定语)“whose”表示谁(可以为人也可以为物)的(东西)例:A child whose parents are dead is called an orphan.双亲都死了的孩子叫做孤儿。(“whose parents”表示那个孩子的双亲)He lives in a room whose window faces south.他住的那个房子的窗户是朝南的。(“whose”表示那个房子的窗户)关系代词:在句中作主语、宾语或定语。1. that既可代表事物也可代表人,“which”代表事物;它们在从句中作主语或宾语,作宾语可省略“that”在从句中作宾语时常可省略关系词,“which”在从句省略。eg:This is the book (which)you want.2.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,但有的则放在它前面的位置。3. 代表物时的that常被省略;c)被形容词最高级修饰时;既有人又有物时;e)整个句中前面已有“which”,“why”行关系副词:在句中作状语关系副词=介词+关系代词why=for whichwhere=in/ at/ on which(介词同先行词搭配)when=during/ on/ in/1. “where”是关系副词,当然也不用“that”引导。By the time when you arrived in London, we had stayed there for two weeks. 当你到达伦敦的时候,我们在那里已经待了两个星期。I still remember the place where I met her for the first time. 我仍然记得我第一次见到她的地方。
