如何合并定语从句句子
导语：如何合并定语从句句子？首先定语从句是一个简单句跟在一名词或代词后（先行词）进行修饰限定，就叫做定语从句。下面是小编给大家整理的相关内容，希望能给你带来帮助!
（一）如何合并定语从句句子
将两个句子中相同的名词其中一个去掉,将整句挪到那个完整句子的后面,再在中间添上先行词（关系代词、关系副词）即可
举例：
1.The young lady act very well.We talked about her just now.
2.He laughed at the girl .The girl's hair was yellow.
3.The films was quite moving.We saw it last night.
合并：
1.The young lady who we talked about just now acts very well.
2.He laughed at the girl whose hair was yellow.
3.The film which(that) we saw last night was quite moving.
（二）定语从句简介：
定语从句，一个简单句跟在一名词或代词后（先行词）进行修饰限定，就叫做定语从句。在主句中充当定语成分。被修饰的词叫先行词。定语从句不同于单词作定语的情况，它通常只能放在被修饰的词（即先行词）之后。
定语 从句由关系词（关系代词、关系副词）引导，关系代词、关系副词位于定语从句句首。
定义
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，在从句中所起作用如下：
Is he the man who/that wants to see you?
他就是想见你的人吗？（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
它们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 prosperitywhich / thathad never been seen before appears in the countryside. 农村出现了前所未 有的繁荣。（which / that在句中作主语）
The packagewhich / thatyou are carrying is about to come unwrapped. 你拿的包快散了。(which / that 在句中作宾语）
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）when, where, why
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，例 如：
There are occasions when (on which) one must yield. 任何人都有不得不屈服的时候。
Beijing is the place where (in which) I was born.北京是我的出生地。
Is this the reason why (for which) he refused our offer? 这就是他拒绝我们帮助他的理由吗？
2）that代替关系副词
that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从 句，在非正式文体中that常被省略（正式文体中不可省略），例如：
His father died the year (that / when / in which) he was born. 他父亲在他出生那年逝世了。
He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十 年前居住过的地方。
③判断关系代词与关系副词
方法一： 用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要 求用关系代词。例如：
（错） This is the mountain village where I visited last year.
（错） I will never forget the days when I spent in the countryside.
（对） This is the mountain village (which) I visited last year.
（对） I'll never forget the days (which) I spent in the countryside.
习惯上总把表地点或时间的名词与关系副词 where, when联系在一起。此两题错在关系词的误用上。
方法二： 准确判断先行词在定语从句中的成分(主、谓、宾、定、状)，也能正确选择出关系代词/关系 副词.先行词在从句中作主、定、宾语时，应选择关系代词；先行词在从句中作状语时，应选 择关系副词。
例如：（对）Is this the museum which you visited a few days ago?
（对）Is this the museum where the exhibition was held?
句子合并定语从句
学习定语从句免不了要进行句法结构和语法成分的分析，而这往往是学生的薄弱环节，故此，在学习定语从句之前，学生应打好两方面的基础。以下是关于句子合并定语从句，欢迎阅览!
句子合并定语从句：
1.He has two sons .They both joined the army three years ago
2.He visited the Summer Palace this summer.He went there four years ago
3.He lied to his mother.It made her very angry
4.I have many books.Some of the books are about English
5.He met Liu Xiang in the street the other day.It made overjoyed
定语从句解题方法
一、选准关系代词和关系副词
在定语从句中，关系代词或关系副词都代替先行词在从句中充当一定的成分，如果该从句中缺少主语、表语、宾语或定语，就要用关系代词来连接从句;如果从句中缺少状语，就得用关系副词来连接从句。例如：
(1) I still remember the days which / that we spent together.
(2) I still remember the days when we worked together.
二、了解仅用that 引导限制性定语从句的几种情况
that 在限制性定语从句中既可指人又可指事或物。在下列情况下，只能用that 来引导定语从句：
1. 先行词是all , much, few, little, everything, anything, nothing 等不定代词时。例如：
Is there anything that you want to buy?
2. 先行词被all, few, little, much, every, some, no等词修饰或被the only, the very, the same, the last 等限定词修饰时。例如：
These are all the pictures that I have seen.
This is the very dictionary that is of great help.
3. 先行词既指人又指物时。例如：
My father and his teacher talked a lot about the things and the persons that they could remember.
4. 关系代词在定语从句中作表语时。例如：
Our school is not the one that it used to be.
5. 先行词被形容词最高级或序数词修饰时。例如：
This is the best English film that I have ever seen.
The first English novel that I read was A Tale of Two Cities.
6. 主句是who 或which 引导的特殊问句时。例如：
Who is the girl that is standing under the tree?
Which is the machine that we used last Sunday?
三、把握“介词+关系代词”结构中介词的选用
介词的选择与主句中先行词的搭配密切相关。例如：
That's the reason for which he was late for school.
This is the book on which I spent 8 yuan.
注意：
1. 定语从句中谓语动词是含有介词的动词短语时，介词应放在动词之后，不能拆开放在关系代词前。例如：
This is the key which you are looking for.
This is the baby whom you will look after.
2. 该结构中，关系代词指人时用whom，指物时用which.
四、弄清as 和which 引导的非限制性定语从句指代整体时的区别
1位置上的区别：
as 引导的非限制性定语从句的位置比较灵活，可以放在主句前，也可以放在主句后，还可插在主句的中间;而which 引导的非限制性定语从句只能放在主句之后。例如：
As is known to us all, the earth turns around the sun.
The earth, as is known to us all, turns around the sun.
The earth turns around the sun, as is known to us all.
The earth turns around the sun, which our parents once told us when we were very young.
2词义与联系上的区别：
as 引导的非限制性定语从句与主句之间有着较为密切的上下文联系，as 本身含有“正如”之意;而which 引导的非限制性定语从句与主句之间在逻辑意义上近似并列句，which 本身表示“这”或“这一点”之意。例如：
Light travels faster than sound, as we all know.
Jack came late for school, which made his teacher angry.
五、注意定语从句的主谓一致性
关系代词在定语从句中作主语时，从句的谓语必须与先行词保持人称和数的一致。例如：
Tom is one of the boys who are from the USA.
Tom is the only one of the boys who is from the USA.
六、保持主句的完整性并避免从句成分的重叠
1. 在定语从句中，不管出现任何情况，主句的结构必须完整，即主句必须有主语和谓语，缺一不可，否则，整个主从复合句就无法成立。试比较：
(1)Is this factory _______ we visited last week?
(2)Is this the factory _______ we visited last week?
A. which B. where C. what D. the one
分析：
第一题缺少表语，只有填D项才能保持主句的.完整性，而其他的选项均为干扰项。
第二题主句本身完整，应填的关系代词在从句中作visited 的宾语，故应选A项。
2. 从定语从句中，关系代词或关系副词已经代替先行词独立地或与相应的介词一起在定语从句中充当了一定的成分，因此在定语从句中就不能再出现与关系代(副)词重叠的成分。例如：
错句：Is this the train that they took it last Sunday?
分析：该题中that 已经代替先行词the train 在定语从句中充当及物动词took 的宾语，故重叠出现的宾语it必须删去。
总之，突破了以上六道难关，定语从句中的难题便会迎刃而解。
