定语从句（3）从句的本质从句的本质是：句子作成分/词类在简单句中，成分都是由单词或短语充当的：I know you.主语是I ；谓语是know ；宾语是youI enjoy reading novels.主语是I ；谓语是know ；宾语是reading novels（动宾短语）I know he is ill.主语是I ；谓语是know ；宾语是he is ill（句子）我们可以看出：最后的句子He is ill 是作了句子成分的，作宾语，因此可以叫它为“宾语从句”从另一个角度来说：这个句子相当于一个名词，因此可以叫做“名词性从句”That she finished reading an English novel surprised us all.上面的句子当中，句子She finished reading an English novel作了主语，因此叫“主语从句”，也相当于名词，还可以叫做“名词性从句”She finished reading an Englishnovel yesterday. She finished reading an Englishnovel at the age of 12.She finished reading an Englishnovel when she was 12.从上面的变化情况我们可以看出，从单词作成分，短语作成分到句子作成分，作的都是状语，因此从句叫“状语从句”，或叫“副词性从句”。
The little girl finished reading an English novel. The girl in school uniform finished reading an English novel.The girl who is 12 finished reading an English novel.从上面的变化情况我们可以看出，从单词作成分，短语作成分到句子作成分，作的都是定语，因此从句叫“定语从句”，或叫“形容词性从句”。
定语从句(The Attributive Clause)（三）一、相同先行词使用不同的关系词：我们前面讲过：1)当先行词是表示时间的名词时，用关系副词when;例如：I will remember the day when I joined the Party.2)当先行词是表示地点的名词时，用关系副词where;例如：This is the house where I was born.3)当先行词是表示原因的名词时，用关系副词why;例如: This is the reason why he was late.而事实上并非如此。
我们看下面的一组句子：1. I will remember the day______ I joined the Party.I will remember the day______ we spent together.在第1组句子中，我们得到答案：a) I will remember the day _when__ I joined the Party.b) I will remember the day that/which_ we spent together.有的同学可能要问同样是表示时间的先行词the day，为什么第一句用关系副词when，而第二句关系代词that/which呢？我们可以把a)句I will remember the day ______I joined the Party.拆开就得到两个句子:①I will remember the day.②I joined the Party on the day.在这两个句子中先行词是物the day，所以我们用关系代词that/which，根据句意可知第一句为主句，所以我们得到: I will remember the day that/which I joined the Party on.把介词on提前，即得：I will remember the day on which I joined the Party而on which=when,亦即：I will remember the day when I joined the Party.所以第a)句填when.我们可以把b)句I will remember the day______ we spent together..拆开就得到两个句子:①I will remember the day.②we spent the day together.在这两个句子中先行词是物the day，所以我们用关系代词that/which，根据句意可知第一句为主句，所以得到:I will remember the day that/which we spent together.所以第b)句填that/which.我们再看一组句子：a)This is the house _______I was born.b) This is the house ________I was born in.我们可以把a)句This is the house _______I was born拆开就得到两个句子:①This is the house.②I was born in the house.在这两个句子中先行词是物the house，所以我们用关系代词that/which，根据句意可知第一句为主句，所以我们得到:This is the house that/which I was born in.把介词in提前，即得：This is the house in which I was born.而in which=where,亦即：This is the house where I was born..所以第a)句填where.我们可以把b)句This is the house _______I was born in.拆开就得到两个句子:①This is the house.②I was born in the house.在这两个句子中先行词是物the house，所以我们用关系代词that/which，根据句意可知第一句为主句，所以我们得到:This is the house that/which I was born in.所以第b)句填that/which.我们看第三组句子：a)This is the reason ________he was late.b) This is the reason ________he gave.我们可以把a)句This is the reason ________he was late.拆开就得到两个句子:①This is the reason.②He was late for the reason.在这两个句子中先行词是物the reason，所以我们用关系代词that/which，根据句意可知第一句为主句，所以我们得到:This is the reason that/which he was late for.把介词for提前，即得：This is the reason for which he was late.而for which=why,亦即：This is the reason why he was late..所以第a)句填why.我们可以把b)句This is the reason ________he gave.拆开就得到两个句子:①This is the reason.②He gave the reason.在这两个句子中先行词是物the reason，所以我们用关系代词that/which，根据句意可知第一句为主句，所以得到: This is the reason that/which he gave.所以b)句填that/which.从以上三组例子，我们可以看出，当先行词是表示时间、地点、原因的名词时并不一定用关系副词when, where, why;而可以用关系代词that/which。
在看本文之前请先看看关系代词和介词+关系代词引导的定语从句我们首先来看看最常见、最简单的where:(1) Where do you live?你住在哪儿？(2) Where are my keys?我的钥匙在哪儿？从上面可知，where最基本的意思为：在哪儿(里)其实定语从句中的where也是类似的，只是没有疑问：在……(地方)如：(3) This is the room where the children sleep.从句where the children sleep的意思为：孩子们在这个房间睡觉。
(4) The town where I grew up is small.从句where I grew up的意思为：我在那个镇长大。
这里where更具体一点就是：在先行词(那个地方)现在我们再来看看在定语从句第一、二部分讲的还原法：上面的(3)、(4)两句，从句都有"在……"的意思，先行词可以直接还原到定语从句中去吗？当然不行，先行词只是一个名词/代词，它本身并没有“在……”这个意思。
因此：表示地点的先行词后面是用关系代词还是关系副词的方法：(1). 如果从句需要加一个介词(“在……”)，就用关系副词where；(2). 如果从句不缺介词(“在……”)，就用关系代词：第一种情况：已经有了介词“在……”第二种情况：不需要介词“在……”(直接作主语、宾语、表语或表示所属关系) 例如：例3的先行词还原到从句变为：The children sleep the room.这个句子the room前面需要加上介词(in)才对。
所以用关系副词where。
如果这个句子改动一下变为：(5) This is the room _______ the children sleep in.这个句子的定语从句部分已经有介词in，先行词可以直接还原(作介词宾语)：The children sleep in the room.因此，此题用关系代词that/which或省略。
定语从句三要素1.先行词；2.引导词；3.引导词再从句中的成分。
定语从句（也称关系从句、形容词性从句），是指一类由关系词引导的从句，因为这类从句的句法功能多是做定语，所以曾被称为定语从句，这类从句除了可以做定语之外，还可以充当状语等其它成分。
1.先行词：被定语从句所修饰的名词或代词①指人的先行词②指物的先行词先行词还可以是前面整个句子所叙述的事情。
He has passed the driving test, which surprises all of us.(which替代前面所叙述的事情) 先行词2.关系词：引导定语的词(1)关系词的作用①替代前面的先行词（替代作用）②连接主句和定语从句（连接作用）③在定语从句中作句子成分（成分作用）(2)关系词的分类①标准：根据关系词在从句中做的句子成分种类②关系代词：在从句中做主，宾，表，定（that/which/who/whom/whose/as）③关系副词：在从句中作状语(When/where/why)3.定语从句：用来做定语，修饰限定先行词的句子1.限制性定语从句：对先行词起限定修饰作用。
He is a teacher who works at our school.2.非限制性定语从句：对先行词起补充说明作用(先行词与定语从句之间有逗号隔开)Beijing, which is the capital of China, is a beautiful city with a long history.比较：He has two sons, who work in the same company. (He has only two sons.)He has two sons who work in the same company. (Perhaps he has two more sons)。

由于限制性定语从句与主句的关系较紧密，所以，融合法多用于翻译限制性的定语从句，尤其是there be句型中的定语从句。
此外，融合法也多见于主句过于简单，而定语从句较复杂，重心在定语从句的句子。
我们举例说明。
1)There is a girl who is waiting for you downstairs .2)We used a plane of which almost every part carried some indication of national identity .3)We in America desperately need more people who believe that the person who commits a crime is the one responsible for it .上面这三个句子中出现了四个定语从句，其中第三个句子我们重点以第一个定语从句为例。
第一个句子是there be句型，其定语从句是who is waiting for you downstairs;第二个句子主干是we used a plane，从句是of which almost every part carried some indication of national identity，由此可见，本句主句很简单，从句较复杂，且重点信息都在从句里。
第三个句子主干是we in America desperately need more people，从句是who believe that the person who commits a crime is the one responsible for it，这个从句中嵌套了一个that引导的宾语从句和一个who引导的定语从句，因此，也具有主句简单，从句复杂的特点，且核心信息偏重于第一个who从句上。

初中英语语法大全：定语从句摘要：语法是掌握英语的一个基础，打好这个基础会使你分析文章更容易，也能够写出很好的句式，小编整理了初中英语语法大全，供大家学习参考。
1在复合句中做定语的从句称为定语从句，它可以用来修饰名词或代词。
被定语从句修饰的名词或代词叫先行词。
定语从句必须放在先行词后面。
2引导定语从句的词通常被称为关系词。
关系词一般位于先行词与定语从句之间，且作为定语从句的一个成分。
关系词又分为关系代词和关系副词。
I 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？（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。
★这篇《英语语法顺⼝溜：定语从句3 - that⽤法》，是⽆忧考特地为⼤家整理的，希望对⼤家有所帮助！
that⽤法真有趣，两个地⽅它不去；
逗号后边它不去，介词之后不考虑；
That做为关系代词，不可⽤在⾮限制性定语从句中，即不可⽤在逗号后边；定语从句中介词之后也不可使⽤。
在逗号或介词后，指物时⽤which,指⼈时⽤who或whom。
例句1）They arrived at a farmhouse, in front of ______sat a small boy.
A. whom
B. who
C. which
D. that
解析：在介词of之后指物，选择C which。
例句 2）The engineer with _____my father works is about 50 years old.
A. whose
B. who
C. which
D. whom
解析：选择 D whom。
介词后指⼈。
例句 3）The letter is from my sister, ______is working in Beijing.
A. which
B. that
C. whom
D. who
解析：选择 D who。
逗号后指⼈，在定语从句中做主语。
初识定语从句一、了解定语从句及相关术语1. 定语从句：修饰一个名词或代词的从句称为定语从句，一般紧跟在它所修饰的先行词后面，相当于形容词在句中作定语。
2. 先行词：被修饰的名词或代词叫先行词。
3. 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。
关系代词有that，which，who，whom，whose，as等；关系副词有where，when，why等。
关系词有三个作用：1.连接作用（即引导定语从句）。
2.代替先行词3在定语从句的担当一个成分。
He is the man who I want to see.他就是我想见的人。
先行词关系词定语从句二、掌握关系代词及其作用最常用的关系代词是who, whom, whose, that，which和as。
关系代词同时起了两个作用。
它们可以像别的代词一样，可以代表一个名词，在定语从句中用作主语或宾语，同时，它们又起到了连词的作用，把主句和从句连接起来。
1. who指人，在定语从句中一般做主语。
如：Do you know the man who is speaking to your father? 你认识和你爸爸讲话的那个人吗？(定语从句修饰先行词the man，who在定语从句中作is speaking的主语）This is the stranger who helped us yesterday. 这是昨天帮助我们的那个陌生人。
She is the girl who works hard at maths. 她就是那个努力学习数学的女孩。
2. whom指人，在定语从句中作宾语。
在口语或非正式文体中，whom可以省略。
如：He is the man (whom) we just talked about. 他就是我们刚才谈论的那个人。
The boy (whom) we met in the street yesterday is my classmate.我们昨天在大街上遇到的那个男孩是我的同学。
定语从句三部曲1. 找出先行词；2. 确定先行词在从句中的成分：主语，宾语，状语；3. 选择正确的关系词。
几个关系代词的基本用法that: 可指人或物；可作主语，宾语。

The writer and his novel ____ you have just talked about is really well known . ( )2. The most important thing ____ should be done right now is how to stop him from going on.()3.
