(完整版)定语从句语法详解
定语从句语法专题（Attributive Clauses）教案一. 定语从句的概述:1.定语从句：在复合句中，修饰某一名词或代词的从句叫定语从句。
在句中做定语，被修饰的名词或代词，叫做先行词。
从句通常放在先行词之后，由关系词（关系代词或关系副词）引导。
其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般紧跟在它所修饰的先行词后面。
eg She is the girl（who got the first prize.）girl先行词who充当从句主语, 从句做定语修饰girlThis is the boy who broke the window.这就是打破窗子的孩子。
the boy是先行词, who broke the window是限制性定语从句, 明确指出theboy是打破窗子的那个孩子,who 在从句中充当主语That is the house where he lived ten years ago.He is the man who/that lives next door.He is the man who I want to see.先行词关系词定语从句复合句: 是由一个主句和一个或一个以上的从句构成的句子, 复合句中的主句和从句都具有完整的的主语和谓语, 主句是复合句的主体, 可以独立存在, 从句需要有一个连词引导, 是修饰说明主句的, 不能独立存在, 根据在句中的不同作用, 从句可以分为三类: 定语从句, 名词性从句, 状语从句。
二. 引导定语从句的关系词有两大类:1.关系词：引导定语从句的关联词称为关系词，关系词有关系代词和关系副词。
关系代词: that, who, whom, whose, which, as（主, 宾, 定）关系副词: when, where, why.（状语）2.关系词的作用:（1）引导定语从句, 在先行词和定语从句之间起连接作用；（2）代替先行词在句中充当成分。

(Never before had I heard of that.Were I you, I would do it.)巧记so的替代结构So I do, so I do, 正常语序跟着so,“的确如此”、“是这样”，前后主语要一样。
So do I，so do I，倒装语序跟着so，表示某某“也同样”，前后主语不一样。
I do so, I do so，“do so” 不变放后头。
表示“做了那件事”，代替前言免重复。
反身代词的用法歌诀反身代词表自身，句中可作两成分。
表示强调同位语，宾语动作回自身。
（反身代词有两种功能，一是表示强调，用作同位语；二是表示反身功能，在句中作宾语和表语。
）关系代语用法歌诀关系词，引定从，它们用法要分清。
that可以作主、宾，指人指物都能行。
which用来指代物，主语宾语都可充。
who和whom来指人，作主作宾各不同。
whose一词作用大，表人表物都能用。
that与which区别歌诀that, which不一般，同指物时可互换。
不定代词为先行，只有that才可用。

10 定语从句
在下列情况下，一般习惯用that 而不用which。 当一个句子有两个定语从句，其中一个已用 which，另一
个则用that。如：We bought a present which they made
themselves that had never been seen before. 在here be或there be结构开头的句子中，多用that。如： Here’s the book that you want.
关系副词
when, where, why
分析关系词在定语从句中的作用 1) Do you know the man who/that is standing over there?
指人 作主语 注意谓语动词
2) The girl that/who/whom we were talking about is Joan.
The Attributive Clause
定语从句
定义：在复合句中， 修饰某一名词或代词的
从句叫做定语从句。如：
1) Do you know the man who/that is standing over there?
2) The girl that/who/whom we were talking about is Joan.
3) Did you see the pen that/which I lost yesterday?
4) He told me the date when/on which he joined the
League. 5) The place where/in which he lives is far away from here 6)Do you have anything that you want to say for youself?
定语从句做题三大步骤
定语从句做题三大步骤定语从句做题三大步骤定语从句做题三大步骤篇一先行若是不定代，that就把which 踹；当先行词为anything，everything，nothing，all，any，much，many，one等不定代词时，只能使用“that”, 不用“which”。
例：Is there anything that I can do for you? 我能给你做点吗？先行词前有两数，就用that定无误；当先行词是基数词或序数词修饰时，只能使用“that”，不用“which”。
例句： That is the second time that I have been to Japan. 那是我去日本的第二次。
The two buildings that lay on the River Thames fell down last week.坐落在泰晤士河岸边的那两座大楼上星期倒塌了。
先行词前最高级，还用that必无疑；当先行词是形容词最高级或被形容词最高级修饰时，只能使用“that”, 不用“which”。
例句：This is the most wonderful time that I have ever had.这是我度过的最美好的时光。
句中若有there be, that应把which替；例：There is no evidence that animals possess a mysterious sixth-sense allowing them to predict natural disasters. 说动物拥有神秘的第六感，可以预知自然灾害，这是没有根据的。
先行主中做表语，避免重复从句里；例句：1）This is not the hospital that it used to be.这已经不再是以前那座医院了。
2）Mr Thomson is not the man that he was.汤姆森先生已经不再是以前的他了。
虚拟语气口诀与总结
虚拟语气总结1一种定语从句：It’s time that+did2两种目的状语从句：so that/in order that+ can/may/could/might +doin case\lest\for fear以防that+should do3三种随时变化句：①wish 现在→did/wereif only ＋过去→had doneas if/though 将来→could/would do②would rather＋现在/将来→did/were过去→had done③现在：if+did/were, would+ do过去：if+had done, would+ have done将来：didif+ were to do, would+ doshould do注意：除了由if引导的虚拟条件句外,还有倒装条件句,即把were、had或should提前；混合时间句,虚实错综句,以及含蓄条件句,即由or, otherwise, with, without, but for来引导的;4四种名词性从句：①当表语是important, natural, necessary, possible, strange, arranged, decided, demanded, ordered, requested, suggested, surprising, a pity, no woder时,主语从句要用虚拟语气;例：It’s important that we should help each other.②动词一坚持insist,两命令command, order,三建议advise, propose, suggest,四要求ask, demand, request, require后的宾语从句要用虚拟语气;例：He insisted that he should be sent to the West.注：insist坚持说, suggest暗示,表明时,从句应用陈述语气;如：Her pale face suggested that she was ill.1. Mother insisted that John should go to bed before 9 o’olock.对比：He insisted that I had taken away his dictionary.不是建议、要求、命令或主张2. His suggestion that Tony should be invited to the party was refused.同位语从句对比：His words suggested that he was very angry with me.不是建议、要求、命令③idea, plan以及表示“坚持,命令,建议,要求”等动词的同源名词作主语时,表语从句用虚拟语气;例：My suggestion is that we should hold a class meeting.④idea, plan以及表示“坚持,命令,建议,要求”等动词的同源名词后的同位语从句要用虚拟语气;例：The office gave an order that his soldiers fight back bravely.If +were/ did 动词过去式,主语+情态动词would, could, might, should+do用来表示对现在情况的假设1.

定语从句学习口诀■山东刘永科一、学习定语从句概述“定语从句”，顾名思义，就是句子作定语。
它是英语学习的重点和难点，也是各类英语考试，尤其是高考的必考项目。
它是复合句中三大从句（名词性从句、状语从句和定语从句）之一，也是最难掌握的一种从句。
定语从句的难点在于它的结构特殊，即“先行词+关系代词（关系副词）+从句”。
许多学生分不清哪是先行词，甚至忽略先行词的概念，因而不能正确使用关系代词或关系副词，更不清楚定语从句中的一些特殊情况。
因此，要想掌握定语从句，就必须弄懂定语从句的本质，掌握其要点：1. 什么叫先行词？准确判断出定语从句所修饰的先行词；2. 关系代词和关系副词有何区别，正确使用关系代词或关系副词；3. 介词置于关系代词之前的情况；4. 关系代词或关系副词的省略；5. 限制性定语从句和非限制性定语从句的区别；6. 定语从句与强调句型和同位语从句的区别。
二、原创定语从句学习口诀目前，鉴于语法书和其他教辅对该问题讲解得比较复杂，甚至有些混乱，读者对于定语从句以及关系代词和关系副词的用法，经常混淆不清。
结合自己多年的教学经验，我特地编写了《定语从句口诀》，并辅以【讲解】。
【口诀】除了让学生背诵之外，更要弄懂每句口诀的含义。
该口诀包含了定语从句的基本内容。
《定语从句口诀》力争做到：内容全面，归纳条例；思路清晰，例句恰当；押韵上口，适合背诵。
（口诀一）定语从句真奇妙，关系代（副）词来引导，定语从句分两种，是否限定看逗号。
（口诀二）which指物who指人，地点where 时间when.that人或物均可，why 之前是reason。
（口诀三）从句当中作宾语，whom可以代替who,为了句子更简练，关系代词可省去。
（口诀四）关系若是表所属，whose用法不可无。
除此之外还有啥，whom, which 力口of。
（口诀五）关系代词不一般，介词经常用在前，此时不用that, who，which, whom 才安全。
三、定语从句“口诀一”详解定语从句真奇妙，关系代（畐U）词来引导，定语从句分两种，是否限定看逗号。
该口诀的意思是，定语从句由关系代词（which, that, who, whom, whose）和关系副词（where, when, why）来引导。
请同学们牢记这8个词。
定语从句分“限制性定语从句”和“非限制性定语从句”两种，前者表示与主句的关系比较密切，它说明先行词的性质、身份、特征等状况。
如果去掉，则会影响句子意思的完整。
后者表示与主句的关系不十分密切，只是对先行词作些附加说明而已。
如果去掉，主句意思仍然清楚完整。
它跟主句之间常用逗号分开，翻译时通常不译作定语，而是单独译成与主句并列的句子。
请比较：Tom is a boy who ofte n helps others.汤姆是一个经常帮助别人的男孩。
（who ofte nhelps others是限制性定语从句。
如果去掉，Tom is a boy.这个句子就没什么意义。
）Yesterday I met Tom, who seemed a little upset.昨天我见到了汤姆，他看起来有点心烦意乱。
（who seemed a little upset是非限制性定语从句。
如果去掉，Yesterday I met Tom.仍有意义。
）又如：A doctor is a person who looks after people's health. 医生就是负责人们健康的人。
This is the diam ond which the lady has lost. 这就是那位女士丢失的钻石。
The school where I studied for only two years was three kilometers away. 我学习了仅两年的那所学校离家3公里远。
I still remember the time when I first traveled by plane. 我仍然记得第一次坐飞机旅行的时间。
（以上为限制性定语从句）Last night I saw a very good film, which was about the Second World War. 昨晚我看了一部非常好的电影，它是关于第二次世界大战的。
My parents live in my hometown, which is about 30 kilometers from here. 我的父母住我的家乡，离这里大约30公里。
Alice, who is a dista nt relative of mine, studies in Yale now.爱丽丝是我的一位远房亲戚，她现在耶鲁学习。
The house, where a murder case happe ned last year, has got a lovely garde n.那栋房子有—个漂亮的花园，去年那里发生过一起谋杀案。
（以上为非限制性定语从句）四、定语从句“口诀二”详解which指物who指人，地点where时间when,that人或物均可，why 之前是reason。
该口诀的意思是，选用什么样的关系代词（或关系副词），是由先行词决定的。
定语从句所修饰的词叫做先行词；连接先行词和定语从句的词叫做关系词（包括关系代词和关系副词），也叫引导词。
关系词不仅在先行词与定语从句之间起连接作用，而且也充当定语从句中的一个成分。
例如：They planted some trees which didn ' t need m他们种植了一些不大需要水的树木。
（which指物）The foreig ner who visited our school yesterday is from Can ada .昨天参观我们学校的那位外国人来自加拿大。
（who指人）This is the house where the old scientist once lived.这是那位老科学家曾经居住过的房子。
（为了押韵才说"地点where”。
意思是说，先行词是地点时，关系词用where。
）I will never forget the day whe n I joi ned the Youth League. 我将永远不会忘记我加入团的那一天。
（为了押韵才说“时间whe n”。
意思是说，先行词是时间时，关系词用whe n。
）Do you know the man that is reading a book over there? 你认识正在那儿读书的那个人吗？（that人或物均可）This is a supermarket that sells a variety of goods.这是一家出售各种各样商品的超市。
（that人或物均可）I don ' t know the reaswhy he is late.我不知道他迟到的原因。
（为了押韵才说“why之前是reason”。
意思是说，先行词是原因reason时，关系词用why。
）【注意】当定语从句由关系副词where, when或why引导时，可以用介词+which"代替。
例如：This is the house where the old scientist once lived. = This is the house in which the old scie ntist once lived.I will n ever forget the day whe n I jo ined the Youth League. = I will n ever forget the day on which I jo ined the Youth League.She came around to expla in the reas on why she was abse nt from the meet ing. = She came around to explain the reason for which she was absent from the meeting.【注意】并非所有的地点、时间或原因，后面的定语从句都要用where, when或why引导。
如果定语从句中缺少主语或宾语，那么，就要用that或which引导。
例如：This is the house that/which （不用where） my father built last year. 这是我父亲去年建造的房子。
（作定语从句的宾语）Do you still remember the days that/which （不用when） we spent in the countryside? 你是否还记得我们在乡下度过的那些日子吗？（作定语从句的宾语）I won ' t listen to the reason that/which不用why）you have given us.我坚决不听你给我们提供的那个理由。
（作定语从句的宾语）五、定语从句“口诀三”详解从句当中作宾语，whom可以代替who,为了句子更简练，关系代词可省去。
该口诀的意思是，如果关系代词在定语从句中作了宾语，那么就可以省略。
此时，指人的关系代词whom可以代替who，当然也都可以省略。
具体地说，who和whom二者都用于指人。
语法规定，who在定语从句中作主语，whom在定语从句中作宾语。
但在现代英语中，作定语从句宾语时，用who和whom都可以。
例如：The boy who made a speech just now is my best friend.刚才讲话的那个男孩是我最好的朋友。
(who在从句中作主语，不可省略)I have many friends (who/whom) I can turn to for help whe n in trouble. 我有很多在困难时刻可以求助的朋友。
(who/whom在从句中作宾语，可以省略)【注意】在从句中作介词的宾语且介词提到之前时，只能用whom,不能用who。
农口：I have many friends to whom I can turn for help when in trouble.我有很多在困难时刻可以求助的朋友。
The river which/that runs through the centre of the city brings us lots of pleasure. 穿过市中心的那条河给我们带来了很多欢乐。
( which/that在从句中作主语，不可省略)Do you remember the holiday (which/that) we spent together? 你记得我们一起度过的那个假期吗？( which在从句中作宾语，可以省略)The message (which/that) you are look ing for is in today's China Daily. 你找的信息就在今天的《中国日报》上。
