高中英语知识点归纳名词性从句与定语从句的区别
高中英语知识点归纳名词性从句与定语从句的区别在高中英语学习中，名词性从句和定语从句是两个常见的语法结构。
虽然它们在形式上很相似，但在功能和用法上有很大的区别。
本文将对名词性从句和定语从句进行归纳和区分。
一、名词性从句名词性从句作为主句的主语、表语、宾语或同位语，起到名词的作用。
名词性从句一般由关系词“that、whether/if, who, whom, whose, which”等引导。
下面将具体介绍名词性从句的几种情况。
1.主语从句一个句子的主语可以被一个从句所替代，这个从句就是主语从句。
例如：What he said puzzles me.（他说的话让我迷惑不解）2.表语从句一个句子的表语可以被一个从句所替代，这个从句就是表语从句。
例如：My dream is that I can travel around the world.（我的梦想是能够环游世界）3.宾语从句一个句子的宾语可以被一个从句所替代，这个从句就是宾语从句。
例如：I believe that he will pass the exam.（我相信他会通过考试）4.同位语从句同位语从句是对前面名词性成分进行解释或说明的从句，常用的引导词是“that”。
例如：The news that he won the competition excited me.（他赢得比赛的消息让我兴奋）二、定语从句定语从句用来修饰或限定名词或代词，并且不能单独存在，必须依附于名词或代词。
定语从句一般由关系代词（that, who, whom, whose, which）或关系副词（where, when, why）引导。
下面将具体介绍定语从句的几种情况。
1.关系代词引导的定语从句The book that I borrowed from the library is very interesting.（我从图书馆借的那本书非常有趣）The boy who is talking to Mary is my brother.（正在和玛丽说话的那个男孩是我的弟弟）2.关系副词引导的定语从句Do you still remember the place where we first met?（你还记得我们第一次见面的地方吗）I still remember the day when we had a picnic in the park.（我依然记得我们在公园野餐的那天）三、名词性从句与定语从句的区别总结名词性从句与定语从句最大的区别在于名词性从句本身是一个句子，可以在句子中充当主语、表语、宾语或同位语；而定语从句是一个从句，用来修饰或限定名词或代词。

在先行词和定语从句之间起连接作用的词叫关系词。
一、关系词有关系代词和关系副词两种（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, that，as等。

which was very useful. 他给我买了一本书;非常有用..句中的which was very useful为非限制性定语从句;如果去掉;句子意思仍是清楚的..2. 关系词的区别关系代词that和关系副词why通常只用于引导限制性定语从句;不用于引导非限制性定语从句..如：她收到了老板的邀请;这是她意想不到的..误：She received an invitation from her boss; that came as a surprise.正：She received an invitation from her boss; which came as a surprise.他失去工作的主要原因是他喝酒..误：The main reason; why he lost his job; was that he drank.正：The main reason why he lost his job was that he drank.另外;在限制性定语从句中;关系代词which用作宾语时;如果不是紧跟在介词之后;通常可以省略；但在非限制性定语从句中;不管在什么情况下均不可省略关系代词which..3. 用法注意当一个名词已由其他词语作了完整的表述;这个名词后则不宜再用限制限制性从句;而应改用非限制性定语从句..如：我去看买的房子有一个很漂亮的花园..误：My house which I bought last year has got a lovely garde n.正：My house; ; has got a lovely garden.若要用限制性定语从句;则应将物主代词my改为the;即说成：The house which I bought last year has got a lovely garden.4. 补充说明非限制性定语从句有时形式上是从句;实质上其功用相当于一个并列的分句..如：He said he had no money; which was not true. 他说他没有钱;这不是实话..which相当于but itThen he met Mary; who invited him to a party. 后来他遇到玛丽;玛丽邀请他去参加晚会..who相当于and sheMy father may have to go into hospital; won’t be going on holiday. 我父亲可能需要住院;如果那样他就不去度假了..in which ca se相当于and in that case关系词、关系代词与关系副词用于引导定语从句的词语叫..关系词根据其词性的不同;可分为关系代词和关系副词..引导定语从句的关系词既起连接先行词与定语从句的作用;同时又在定语从句中充当一定的句子成分..1. 关系代词：主要有that;

. 他们指控他是叛徒;他真是叛徒..She talked like a native; which she hardly was. 她说起话来像是个本地人;其实她不见得是..■在非常正式的文体中;代词that后可以接一个修饰它的定语从句;这个定语从句通常用which来引导..如：They say the only real knowledge is that which can be measu red. 据说唯一真实的知识是可以检验的知识..在现代英语中;that which通常用what来代替..如：We have that which =what we need. 我们需要的东西都有了..That which =What many people say is not always true. 很多人说的话并不表示一定是真的..关系代词that用法归纳一、指人的用法t hat用于指人;在定语从句中可用作主语、宾语或表语..如：A driver that has knocked someone down must stop. 撞人的司机必须停车..关系代词that指driver;在从句中作主语He is the man that you have been looking for. 他就是你要找的那个人..关系代词that指man;在从句中作宾语He is not that man that he was. 他已不是过去的他了..关系代词that指man;在从句中作表语二、指物的用法that用于指物;在定语从句中可用作主语、宾语或表语..如：This is the plane that will fly to Tokyo in the afternoon. 这是下午要飞往东京的那架飞机..关系代词that指plane;在定语从句中作主语She was annoyed by something that I had said. 她为我说的某句话而不高兴..关系代词that指something;在定语从句中作宾语Shengzhen is not the city that it used to be. 深圳现在已不是原来的那个城市了..关系代词that指city;在from which与from where的区别有朋友问到 from which与from where 有何区别问题见：;下面是我们的一位特约作者给出的部分回答;摘录如下;供大家参考：……关于from which的用法比较好理解;这里主要说说from where的用法..from where主要有以下两个用法：用法一：用于引导非限制性定语从句;在意义上相当于 and from the re从那儿..如：He hid himself in a tree; from where he could see the enemy in the distance. 他躲在一棵树上;从那儿他可以看到远处的敌人..We went up to the roof; from where we had a good view of th e procession. 我们爬上屋顶;从那儿可以很好地观看游行..用法二：可视为where前省略了the place;即这样用的from where 相当于from the place where;意思是“从……的地方”“离……的地方”..如：From where I stood I could see everything clearly. 从我站的地方我一切都看得清清楚楚..The car stopped short only a few inches from where I stood.汽车在离我站的地方仅几英寸处突然停住..The school was only a few blocks from where she lived. 学校离她的住所只有几个街区的距离..若遇到前面是地点名词的先行词;如何判断用where还是from where 还是from which 请看下面一个句子：I have bought that house; _____I can enjoy the beautiful sc ene of Yangpu Bridge .我们认为这道题填 where 和 from where 语法上都可以但不宜填 f rom which;但两者在意义上稍有区别：I have bought that house; where I can enjoy the beautiful s cene of Yangpu Bridge. 我买下了那栋房子;在房子那可以欣赏到杨浦大桥的美景..I have bought that house; from where I can enjoy the beauti ful scene of Yangpu Bridge. 我买下了那栋房子;从房子那可以欣赏到杨浦大桥的美景..在许多情况下;用不用 from 不会导致语法错误;但会导致语义变化通常情况下是;如果没有 from;意思会不够明确和清楚..比较：He hid himself under the bed; from where he could hear what they were talking. 他躲在床下面;他可以从床下听到他们谈话..句中的 from where 可理解为 from under the bed;意思是“从床下面”He hid himself under the bed; where he could hear what they were talking. 他躲在床下面;在床那儿他听到他们谈话..句中的 wher e 可指为“在床边”“在床上”“在床下”等;意思不够明确如何使用“介词+关系代词”结构对于“介词+关系代词”结构的使用;重点是要弄清其中的介词如何确定和判断..归纳起来;有以下几点方法：1. 根据与定语从句中动词的搭配来确定介词..如：Water is the natural medium in which fish live. 水是鱼类赖以生存的自然环境..注意搭配live inThe documents for which they were searching have been recov ered. 他们找寻的文件已经找到了..注意搭配search forThis is a subject about which we might argue for a long whi le. 这是一个我们可能长时间争论的问题..注意搭配argue about 注意;对于那些由动词与介词构成的短语动词;通常不宜将它们拆开使用;此时应注意介词的位置应..如：The boy whom my sister is looking after is getting better.不能说成：The boy after whom my sister is looking is getting better.2. 根据与定语从句中形容词的搭配来确定介词..如：Physics is the subject in our school in which every student is interested. 物理是我们学校每个学生都很感兴趣的课程..注意搭配 be interested inHe referred me to some reference books with which I am not very familiar. 他我要去参考一些我不熟悉的参考书..注意搭配 be fa miliar with3. 根据与先行词的搭配来确定介词..如：This is our classroom; in the front of which there is a tea cher’s desk. 这是我们的教室;前面有老师的讲台..注意搭配 in the f ront of our classroomI’ll never forget the day on which she said goodbye to me. 我永远不会忘记她与我们告别的那一天..注意搭配 on the day4. 根据句意来确定介词的使用..如：This is the book I got the story. 这就是那本书;从中我读到这个故事..由于句意含有“从……”的意思;所以用介词 from This I did at nine o’clock; after which I sat reading the p aper. 九点钟时我做这事;之后我坐着看报..由于句意含有“在……之后”的意思;所以用介词 after关系代词where与from where有何区别where用作关系副词引导定语从句时;由于它本身在意义上相当于“介词+which”;所以其前通常无需再用介词..如：This is the hotel where =in / at which they were staying. 这就是他们当时住的旅店..She has a safe in her closet where =in which she keeps her jewelry. 她在壁橱内装有一个保险箱存放她的珠宝..但有时我们也可见到from where的用法;这时因为from是一个比较特殊的介词;因为它有时可以后接介词短语作宾语..如：Come out from under the table. 从桌子下边出来..所以;尽管关系副词where在意义上相当于“介词+which”;有时由于语义的需要;也可在where之前使用介词from..如：We went up to the roof; from where we had a good view of th e procession. 我们爬上屋顶;从那儿可以很好地观看游行..关系代词as用法说明一、引导限制性定语从句用在 such; same; as 等之后;引导限制性定语从句..如：I live in the same place as Tom does. 我和汤姆住在同处..He’s not such a fool as he looks. 他并不像看上去的那样愚蠢..He smokes as expensive a cigarette as he can afford. 他抽一种他买得起的最贵的烟..二、引导非限制性定语从句2 单独用作关系代词;引导非限制性定语从句;可放在主句之前、之后或中间;且主从句之间一般要用逗号隔开..如：As was expected; he succeeded at last. 正如我们所料;他终于成功了..I had coffee after dinner; as is my usual practice. 我饭后喝咖啡;这是我的习惯..Freddie; as might be expected; was attending the conference.弗雷迪在参加会议;这是可以预料到的..三、as与which的用法区别① 引导限制性定语从句的区别：as用作关系代词引导限制性定语从句时;它通常只用于 such; same; as 等之后;而which 用作关系代词引导限制性定语从句时;则用于除 such; same; as 之外的其他结构..② 引导非限制性定语从句的区别：which引导非限制性定语从句时;通常只能位于主句后;而as引导的非限制性定语从句位于主句之前、之后或中间..根据从句谓语动词的特点来看;as在定语从句中作主语时;从句谓语通常要有be或别的系动词;但which不受此限制..如：Li Ming was late; which =and this made Mr. Zhang very angry.李明迟到了;这件事使张先生非常生气..不可用as根据句意的逻辑性来看;as引导的定语从句只表示一个众所周知或意料之中的事;但which不受此限制..如：He married her; as which was natural. 他和她结婚了;这是很自然的..He married her; which was unexpected. 他和她结婚了;这是出乎意料的..不可用as■本文摘自中学英语高频词详解词典关系代词whose用法说明whose用作疑问代词或连接代词时;用法比较单一;均表示“谁的”;一般不会出错;这里主要说说它用作关系代词的用法..1. whose用作时;它并不表示“谁的”;而是表示“……的……”;在具体语境需要灵活处理..如：He is the man whose car was stolen. 他就是汽车被窃的人..The boys whose names were called stood up. 叫到名字的男孩们站了起来..You are the only one whose advice he might listen to. 你是惟一可能使他听从劝告的人..2.不要以为whose时;其先行词一定是指人的名词;其实也可以是指事物包括动物的名词..如：It was an island whose name I have forgotten. 这是一座岛;名字我忘了..Wolves are highly social animals whose success depends upon cooperation. 狼是高度群体化的动物;它们的成功依赖于合作..3.不仅可以引导限制性定语从句;也可引导非限制性定语从句..如：My bitch; whose temper is very uncertain; often bites the j udges at dog shows. 我的母狗脾气不稳定;常常在狗展上咬裁判..4.引导定语从句的“whose+名词”;有时可换成其他结构;注意..比较：破了窗户的那座房子是空的..正：The house whose windows are broken is empty.正：The house the windows of which are broken is empty.正：The house of which the windows are broken is empty.正：The house with broken windows is empty.限制性定语从句还是非限制性定语从句下面这道题是考查限制性定语从句还是If a book is in English; __________ may mean slow progress for you.A. thatB. whichC. asD. and it此题应选 A..容易误选 B..许多考生一看到空格前的逗号;就想当然地认为这是非限制性定语从句;从而误选了B..考生可以想一想;假若此题选Bwhich;which 用以引导一个非限制性定语从句;而其前又是一个以if 引导的;那么请问：此句的主句在哪里通过以上分析我们可以知道;既然本句前面有一个条件状语从句;那么后面一句就应该是主句..本题选that; 即为主句主语;全句意为：如果一本书是用英语写的;那么那就意味着你要读得慢些..注意：当从句位于主句之前时;千万不要在主句前误加并列连词或误认为是某种从句..请做以下单选题..如：1.

高中英语知识点归纳定语从句与表语从句的区别
高中英语知识点归纳定语从句与表语从句的区别在学习英语的过程中，我们会遇到很多不同的从句结构。
其中，定语从句和表语从句是两种常见的从句结构。
但是，对于很多学生来说，这两种从句结构往往容易混淆。
因此，在本文中，我们将详细讨论定语从句和表语从句的区别。
定语从句是一种用来修饰名词或代词的从句，它通常在句中作定语，用来对名词或代词进行进一步的说明或限制。
而表语从句则是一种用来说明主语或宾语的从句，它通常在句中作表语，用来对主语或宾语进行补充或说明。
一、定语从句的特点和用法定语从句中的主要特点是：它不能独立存在，必须依附在名词或代词之后，作为其修饰语。
也就是说，定语从句必须与被修饰的名词或代词一起组成一个完整的句子。
定语从句的引导词包括关系代词和关系副词。
常见的关系代词有：who, whom, whose, which, that；常见的关系副词有：when, where, why。
在使用定语从句时，需注意以下几点：1.关系代词who和that常用来修饰人，which和that常用来修饰物；2.关系代词whom常用来作宾语，而who则常用来作主语；3.关系代词whose用来表示所属关系；4.关系副词when用来表示时间，where用来表示地点，why用来表示原因。
下面是一些例句来帮助我们理解定语从句的用法：1. The boy who is standing over there is my brother.（那个站在那里的男孩是我弟弟。
）2. The book which I borrowed from the library is very interesting.（我从图书馆借来的那本书非常有趣。
）3. The house whose windows are broken is abandoned.（那所窗户破碎的房子已经废弃了。
）4. This is the reason why I couldn't come to the party.（这就是我不能来参加聚会的原因。
