定语从句的用法

定语从句的用法

定语从句的用法定语从句是英语中一种常见的语法结构,用来修饰名词或代词。

它通过引导词(关系代词或关系副词)与主句相连,起到限定和具体化名词或代词的作用。

在本文中,我们将深入探讨定语从句的使用方法,以及一些值得注意的细节。

一、引导词的选择1. 关系代词:关系代词主要有“that”、“which”、“who”、“whom”、“whose”等。

选择哪个关系代词要根据所修饰的先行词和在从句中所起的作用来决定。

一般来说,关系代词“that”可以修饰人或物,而“which”只能修饰物;关系代词“who”和“whom”只能修饰人,分别作主语和宾语;关系代词“whose”用来指代所修饰名词的所有格。

2. 关系副词:关系副词主要有“where”、“when”、“why”等。

它们用来引导定语从句,修饰在主句中的名词或代词,并指出时间、地点或原因。

关系副词的使用具有一定的局限性,需要根据具体的情况进行选择。

二、定语从句的位置定语从句通常紧跟在被修饰的名词或代词后面。

例如:1. The book that I borrowed from the library is very interesting.(我从图书馆借来的那本书非常有趣。

)2. The person whom we met yesterday is my uncle.(我们昨天见到的那个人是我的叔叔。

)但是,当被修饰的名词或代词是主句的主语时,定语从句需要放在主句之后。

例如:1. My brother, who is a doctor, lives in London.(我的兄弟是一名医生,他住在伦敦。

)2. The movie, which was directed by Steven Spielberg, won several awards.(这部电影是由史蒂文·斯皮尔伯格导演的,它赢得了几个奖项。

)三、定语从句的省略当定语从句中缺少主语或宾语时,可以通过省略关系代词或关系副词来简化句子。

非常详细的定语从句,状语从句,名词从句的讲解……that,which,where,who,等

非常详细的定语从句,状语从句,名词从句的讲解……that,which,where,who,等

定语从句定语从句是由关系代词和关系副词引导的从句,其作用是作定语修饰主句的某个成分,定语从句分为限定性和非限定性从句两种。

状语从句分为时间状语从句,结果状语从句,让步状语从句,原因状语从句,条件状语从句以及行为方式状语从句。

名词从句包括主语从句,宾语从句,表语从句和同位语从句及there be句型。

一、限定性定语从句1. that即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,that在从句中作宾语时常可省略关系词,which在从句中作宾语则不能省略。

而且,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的前边,但有的则放在它原来的位置2. which作宾语时,根据先行词与定语从句之间的语义关系,先行词与which之间的介词不能丢3. 代表物时多用which,但在带有下列词的句子中用that而不用which,这些词包括all, anything, much等,这时的that常被省略4. who和whom引导的从句用来修饰人,分别作从句中的主语和宾语,whom 作宾语时,要注意它可以作动词的宾语也可以作介词的宾语5. where是关系副词,用来表示地点的定语从句6. when引导定语从句表示时间〔注〕值得一提的是,表示时间“time"一词的定语从句只用when引导,有时不用任何关系代词,当然也不用that引导By the time you arrive in London, we will have stayed there for two weeks.I still remember the first time I met her.Each time he goes to besiness trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc.7. whose是关系代词,修饰名词作定语,相当于所修饰成分的前置所有格8. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时,常用there is来引导二、非限定性定语从句:非限定性定语从句的作用是对所修饰的成分作进一步说明,通常和主句间用逗号隔开,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来说明前面整个句子的情况或主句的某一部分2. 在引导限定性定语从句时,that有时相当于in which, at which, for which或at whichAttitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed. 人们对白日做梦的态度正在改变,这与人们对夜间做梦的看法的变化有非常相似之处。

定语从句(Ⅰ)——that,which,who和whose引导的定语从句

定语从句(Ⅰ)——that,which,who和whose引导的定语从句

1、定语从句的定义在复合句中,修饰某一名词或代词用作定语的从句叫作定语从句。

被定语从句修饰的词叫先行词,定语从句必须放在先行词之后。

引导定语从句的关系词有关系代that,which,who,whom, whose和as以及关系副词when, where和why等。

关系代词在定语从句中可用作主语、宾语、定语等;关系副词在定语从句中作状语。

2、定语从句引导词的用法(1)that的用法that的先行词是人或物,在定语从句中作主语、宾语或表语。

主要特点有:①that在定语从句中作主语时不省略,作宾语时可以省略;②that不引导非限制性定语从句;③that前不加介词例子 Theforeigners that visited our school yesterday are from Canada.昨天参观我们学校的外国人来自加拿大。

(that代替人,作主语)I like the book very much ( that ) my uncle gaveme.我非常喜欢我叔叔给我的这本书。

(that代替物,作宾语)☆只能用that引导定语从句的情况:①先行词被序数词或形容词最高级修饰;②先行词是不定代词all, the one, everything等;③先行词被 any , the only , the last等修饰④先行词既指人又指物时例子Alice is the only person ( that ) I can trustin the office.爱丽丝是办公室里我唯一信任的人。

(先行词被the only修饰只用that)(2)which的用法先行词是物,在定语从句中作主主语或宾语。

主要特点:①which在定语从句中作主语时不能省略,作宾语时可以省略,引导非限制性定语从句时不能省略;②which的前面可以有介词;③which的先行词可以是前面数个的的句子,意为”这使…….;这一点……”。

例子 A computeris a machine which can do many things for us.电脑是一种可以为我们做许多事情的机器。

限定性定语从句的先行词前面不可加其他定语修饰词,并且不用逗号隔开。

2.非限定性定语从句:非限定性定语从句起补充说明作用,缺少也不会影响全句的理解,它与主句之间通常用逗号隔开。

非限定性定语从句前面可以加其他定语修饰词。

非限定性定语从句先行词为专有名词或者具有特指性的名词时,一般不用that。

突破高一语法之一---定语从句

定语从句一、【基础知识】学习who/whom/whose/which/that 引导的定于从句,理解并熟悉其结构。

1)先行词和关系词主句中被定语从句修饰的词叫做先行词,定语从句一般位于先行词之后。

关系词有关系代词和关系副词,用来指代先行词。

关系代词有that/which/who/whom(宾格)/whose(所有格)/as,关系副词有when/where/why2)关系代词的用法*who 指人,是主格,在定语从句中作主语或宾语都可以。

e.g. The girl who is singing is John’s sister. 正在唱歌的女孩是约瀚的姐姐。

(girl是先行词,关系代词who在从句作主语。

在这种情况下也可用that)注:关系代词在定语从句作主语时,其人称和数要与先行词一致。

*whom指人,是宾格,在定语从句只作宾语。

e.g. The man (whom)we talked about will come tomorrow. 我们谈论的那个人明天来。

(先行词是man,关系代词whom在从句作talk about的宾语,在英语口语中可以省略。

在这种情况下也可以用who或that,它们都能指代人,作主语或宾语都可以)*whose多指人,也可指物,指物时。

在指物时可与of which换用,whose是所有格, 在定语从句中作定语。

e.g. Aunt Wang is looking after the little child whose parents have gone to Shanghai.王姨在照看父母都去了上海的那个小孩。

(先行词是the little child, 关系代词whose在定语从句作parents的定语)He lives in the room whose windows ( the windows of which) face south.他住在窗户朝南的那个房子里(the room是先行词, 关系代词whose在定语从句作windows的定语)* that: 指人或物,在定语从句中担任主语或宾语。

定语从句that who which whose的用法

定语从句中的关系代词 that、who、which 和 whose 在使用上各有特点,以下是对它们用法的总结:that:that 可以引导限制性定语从句,用于指代人或物,在从句中作主语、宾语或表语。

当 that 在从句中作宾语时,可以省略。

示例:Do you know the boy that is standing over there? (that 指代人,在从句中作主语)She is no longer the girl that she used to be. (that 指代人,在从句中作表语)I can describe the person (that) I saw. (that 指代人,在从句中作宾语,可省略)who:who 主要用于引导定语从句,修饰表示人的先行词,在从句中作主语或宾语(作宾语时多用宾格 whom,但现代英语中 who 常可替代whom)。

示例:The girl who won the competition is my classmate. (who 指代人,在从句中作主语)The person (whom/who) you met is my friend. (who 或 whom 指代人,在从句中作宾语)which:which 主要用于引导定语从句,修饰表示事物的先行词,在从句中作主语、宾语或表语。

which 还可以引导非限制性定语从句,此时不能用 that 替代。

示例:This is the book which I bought yesterday. (which 指代物,在从句中作宾语)The house, which is very beautiful, is located in the countryside. (非限制性定语从句,which 指代物,在从句中作主语)whose:whose 用于引导定语从句,表示所属关系,其先行词可以是人或物。

定语从句和名词性从句中关系词的用法

定语从句和名词性从句中关系词的用法

定语从句和名词性从句中关系词的用法?定语从句,主语从句,表语从句,宾语从句,同位语从句分别用哪些关系词?如何用?特别是that和what的区别在英语教学中,关系词常常是学生容易混淆的问题。

在某些情况下,学生常常不知道该使用那一个关系词,这个问题常是教学中的重点或难点。

因此,本文就学生在学习关系词“that”、“which”、“whose”、“what” 时经常容易出现问题的几个难点部分进行分析,以便于教学中让学生注意区别它们的用法。

一.在定语从句中关系词用法的差异1.关系代词“that” 与“which” 的区别在限定性定语从句中,我们知道关系词指代人时,常用who、whom 、whose (或that),指代物时常用whi ch 或that 。

例如:例1.Where is the girl who / that sells the tickets? (卖票的女孩子在哪?)例2.I’ve lost bananas which / that I bought this morning. (我把今天早上买的香蕉丢了。

)在上述两个例子中who 和which都可以由that 替代。

但是当先行词是all、little、few 或是由every(thin g)、any(thing)、no(thing)、none、much、only 修饰时,关系词要用that不能用which 。

例如:例3.Is this all that is left? (是不是就剩下这一个了?)例4.Have you got anything that belongs to me? (你那有我什么东西吗?)例5.The only thing that matters is to find our way home .(只有一件事最重要,那就是找到回家的路。

)除上述情况外,当先行词由序数词或最高级修饰时,关系词必须用that(见例6和例7)。

定语从句中that和which的用法

定语从句中that和which的用法

定语从句中的that和which的用法引导定语从句的关系代词有:that(指人或物),which (指物),who (指人).指人时可用that或who ;指物时可用that 或which 。

That和which在从句里都可以做宾语和主语,做宾语时可以省略。

指物时,两者一般可以互换,但在下列情况下只能用that:1)当先行词是all ,any ,anything ,everything ,nothing 或被它们修饰时.例如:Is there anything that I can do for you有什么可以为你做的吗All that can be done must be done .凡是能做的都必须做.2)当先行词被形容词的最高级或序数词修饰时.例如:That is one of the most interesting books that are sold in the bookshop .那是这家书店出售的最有趣的书之一.The first thing that we should do is to get some food .我们该做的第一件事是弄点吃的.3)当先行词有:the only ,the very ,the same ,the last 等修饰时.例如:My necklace is not the only thing that's missing .我的项链不仅是丢掉的东西.4)当主句以who或which开头时,定语从句中引导词用that ,不用which 或who .以避免重复.例如:Who is the girl that is wearing a red coat正穿一件红色外套的女孩子是谁5)当先行词既有人又有物时,用that .例如:The writer and his novel that you have just talked about are really well known .你刚才谈起的那位作家以及他的小说确实很著名.请注意: 以下几种只能使用which的情况:1.引导非限制性定语从句,用which。

引导定语从句的关系代词常见的有that, which, who whom等。关系代词放在先行词和定语从句之间, 起连接作用,同时又作定语从句的一个成份。

先行词:是被定语从句所修饰的词,通 常是名词或代词。 关系词: 是引导定语从句的词,在从 句中替代先行词。 注意: 关系词要在从句中充当一定的 成分。关系代词所替代的词在从句中 不能再出现。
定语从句一般要放在先行词之后。因 此,定语从句在句中的位置随其先行 词位置的变化而变化。如:
Have you seen the photos that I took on my trip? The photo that I took on my trip are on the desk.
that引导的定语从句可以修饰无生命 的东西,也可以修饰有生命的动物或 人。如: What’s the name of the animal that jumps about? Who is the girl that talked to you yesterday?
归纳:that,即指人又指物,作主语或宾语。 which,指物,作主语或宾语。 who, whom指人,who作主语,whom作宾语。 that,which,whom在定语从句中作宾语时,可省去。 1) A plane is a machine ________________ can fly. which/that which/that/ 不填 / 2) The car _______________________ my uncle bought last week was stolen. who/that 3) The students ________________ don’t study hard will not pass the exam. 4) The woman ___________________ you saw in whom/that/ 不填 / the park is our English teacher. 5) He talked happily about the men and books____ that __________ interested him greatly in the school.
