高中英语定语从句详解
![高中英语定语从句详解](https://img.taocdn.com/s3/m/879bc35a03768e9951e79b89680203d8ce2f6aee.png)
高中英语定语从句详解高中英语定语从句详解定语从句主要用于修饰句子中的名词、代词或上文提到的一件事(句子)。
而定语从句的位置常常是紧跟在被修饰的名词、代词或句子的后面。
在被修饰的名词、代词(先行词)与定语从句之间往往有一个关系词将其前后两部分联系成一个整体。
关系词与后面的句子合称定语从句。
1)three signs that indicate a person is suffering from a heart attack三种意味着一个人患心脏病的迹象在这个带有定语从句的短语中:signs是:被修饰的名词;that是:关系词;that indicate a person is suffering from a heart attack是定语从句2)those who drink a lot 那些大量饮酒的人在这个带有定语从句的短语中:those是:被修饰的代词;who是:关系词;who drink a lot是:定语从句。
3)Do you know the name of that girl whose brother is your roommate ?你知道她的哥哥与你同寝室的那位女孩的名字吗?通过上面的演示,我们可以归纳出:(1)定语从句在英语中放在被修饰的词后,翻译成汉语时置于被修饰的词之前,且有汉字“的”(2)定语从句在句子中的位置、结构如下:被修饰的名词/ 代词+ 关系词+ 句子(其中,"被修饰的名词/代词"在语法叫作"先行词".) 要点提示:1)先行词=关系词。
所以先行词在从句中不在出现。
先行词的意义以及它在从句中的语法功能(句子成分)决定关系词的选择。
定语从句中的关系词只有两类:关系代词和关系副词;所有关系词不但都有具体的意义而且都在从句中担任一定的成分。
1)关系代词:who , whom , whose , which , that 等。

![高中英语定语从句讲解及练习较全面](https://img.taocdn.com/s3/m/f021413e0508763230121283.png)
高中英语定语从句讲解与练习定语从句在句中做定语,修饰一个名词或代词,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等。
关系副词有:when, where, why等。
18.1 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,在从句中作主语和宾语。
例如:Is he the man who/that wants to see you? 他就是你想见的人吗?He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。
2〕whose 用来指人或物,〔只用作定语, 假如指物,它还可以同of which互换〕。
例如:They rushed over to help the man whose car had broken down.Please pass me the book whose 〔of which〕cover is green. 3〕which, that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. The package 〔which / that〕you are carrying is about to e unwrapped.18.2 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〕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。

That we need more equipment is quite obvious. 我们需要更多的设备,这是很明显的。

!"#$%Attributive ClauseI. !"#$%&⼀、定义在复合句中,⽤以修饰名词或代词(充当定语)的从句,被称为定语从句。
例如:(1)English is a useful language.(其中形容词useful作定语修饰名词language)English is a language which helps people to communicate effectively with others.(其中“which … others”为定语从句,修饰language)(2)He told me something important.(其中形容词important作定语修饰不定代词something)He told me something that I would never forget.(其中“that … forget”为定语从句修饰不定代词something)在定语从句中,被修饰的名词或代词被称为先⾏词;引导定语从句的词被称为关系词。
重点1.如果没有先⾏词(即被修饰的名词或代词),定语从句也就不存在了。
2.定语从句的关系词都必须在从句中充当⼀定的成分。
⼆、分类定语从句可分为限定性定语从句和⾮限定性定语从句。
1. 限定性定语从句:与主句关系紧密,往往直接跟在先⾏词之后,起到限定的作⽤;2. ⾮限定性定语从句:以逗号“,”隔开主句,主从句的关系相对松散,从句往往只是对先⾏词的补充说明,对主句的意思影响不⼤。
**⼀些⾮限定性定语从句的关系词可以指代主句整句句⼦。
例如:(1) The watch I bought in Switzerland works quite well. 我在瑞⼠买的那块表⾛得不错。
(2) He gave me a vase, which strikes my fancy. 他送了我⼀只花瓶,我很中意。
(3) My father’s old watch gains a bit, as is often the case. 我爸的表快了点,这是常有的事。

在复合句中充当定语的从句叫定语从句。
定语从句的作用相当于形容词,用来修饰主句中的某一名词或代词或整个主句,所以,也称作形容词性从句。
被定语从句修饰的词叫先行词,定语从句一般紧跟在它所修饰的先行词之后。
在先行词和定语从句之间起连接作用的词叫关系词。
关系词有关系代词和关系副词两种。
提示:关系词在定语从句中有三大作用1.连接作用一连接先行词和定语从句。
I gave her all the money that I ha我把我所有的钱都给了她。
(that 连接先特词money和定语从句I had2.替代作用一在定语从句中替代从句所修饰的先行词。
The man who lives next door is a famous teache住在隔壁的那个人是个名师。
(who替代the man)3.成分作用一在定语从句中作主语、宾语、定语或状语。
I like pictures which are painted in the traditional Chinese style.我喜欢传统的中国画。
(which在定语从句中作主语)一、关系代词引导的定语从句引导定语从句的关系代词主要有who, whom, whose, which, th簿。
它们分别代替前面的先行词,并在定语从句中作主语、宾语或定语。

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。

一、定语从句概述定语可以由形容词、名词、代词、数词、分词、副词、不定式以及介词短语等来担任,也可以由一个句子来担任。
在句子中起定语作用的从句称为定语从句。
定语从句在句中的作用相当于形容词,故又称为形容词性从句。
被定语从句修饰的名词叫先行词,引导定语从句的词叫关系词。
二关系词的用法。
关系词可分为关系代词和关系副词。
关系词指代先行词,放在先行词与定语从句之间起连接作用,同时又充当定语从句中的某一种成分(主语、宾语、状语等)。
引导定语从句的关系代词有"at,who,whom,whose,which;关系副词有when,where,why等。
关系词在句子中的指代作用及成分如下表1.关系代词的用法(1)who, whom的用法二者都用于指人。
who在定语从句中作主语、宾语;whom在定语从句中作宾语。
在现代英语里,有时who也可代替whom在从句中作宾语。
作宾语的关系代词who,whom可以省略(介词后作宾语的关系代词除外)。
She was the one who did most of the talking。
大部分时间都是她在说话。
(作主语) The boy who I know studies best in his class.我认识的那个男孩在班上学习最好。
(作宾语)I happened to meet the professor (who/whom) I got to knowat a party. 我碰巧遇见了那位在一次聚会上认识的教授。
(作宾语,whom可用who 代替)whom在从句中作介词的宾语,且介词提到whom前面时,不能用who 代替。
Yesterday I came across a few friends with whom I went to the park.昨天我碰见了几个朋友,我和他们一起去了公园。
(句中的whom 不能用who 代替)whose可以指人也可以指物,在定语从句中作定语。

高中定语从句讲解高中定语从句是英语语法中的一种重要句型,用于修饰和限定名词或代词。
它由一个关系词(如that, which, who, whom, whose, where等)引导,后面跟一个从句。
定语从句可以用来提供更多的信息,以便更准确地描述一个人或物的特征、性质、状态、身份、关系等。
下面是一些关于高中定语从句的讲解要点:1. 关系代词的选择:关系代词分为主格形式(who, which, that)和宾格形式(whom, which, that)。
- 当关系代词在定语从句中做主语时,使用主格形式。
- 当关系代词在定语从句中做宾语时,使用宾格形式。
需要注意的是,宾格形式的关系代词whom在口语中较少使用,通常可以用who代替。
2. 关系副词的选择:关系副词有where, when, why等。
它们引导的从句通常修饰地点、时间、原因等。
3. 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之后,起到对其进行补充说明的作用。
例如: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。
)4. 关系代词和关系副词的省略:当定语从句中的关系代词在从句中作宾语,并且在主句中已经有宾语时,可以将其省略。
例如:The man (whom) I saw yesterday is a famous actor.(昨天我看到的那个人是一位著名的演员。
)5. 定语从句的否定形式:定语从句中的否定形式通常使用not引起的否定词组。
例如:I don't know the reason why he didn't come.(我不知道他没来的原因。
)6. 先行词的指代问题:定语从句中的关系词所指代的先行词通常是前面提到过的名词或代词。
需要注意的是,当先行词是不定代词时,如something, someone, anyone等,关系词通常用that代替。

定语从句:在复合句中起形容词作用,作定语,修饰名词或代词的从句叫定语从句。
先行词:被定语从句修饰的词叫先行词。
关系词:连接先行词和从句的词叫关系词。
注意:
关系词指代先行词,并在句子起连接作用,连接主句和从句,同时又在定语从句中充当成分(主、宾、表、状等)关系词根据其在从句中所充当的成分可以分为:
关系代词:在从句中做主、宾、表、定(that/which/who/whom/whose/as)
关系副词:在从句中作状语(When/where/why)
