如何合并定语从句句子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。

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。

用合并句子法讲解高中定语从句——关系代词
- 194-校园英语 / 基础教育用合并句子法讲解高中定语从句——关系代词重庆市黔江区新华中学校/罗茜【摘要】定语从句是英语句子中构成长难句不可或缺的句型之一，对它的掌握一直是中国学生语法学习中的难点，很多学生无法独立理解和分析，更不用说在作文中的正确使用。
本文旨在用合并两个简单句的方法引入定语从句的演变并讲解定语从句中的关系代词，从而让高中生在定语从句的学习中登堂入室。
【关键词】合并句子 定语从句 关系代词学习背景及基础知识的准备语法是语言的重要组成部分，必然是教师教学过程中的核心内容之一。
在高中语法教学中，定语从句就是教师讲解的重点，却又是许多学生的语法学习中的短板。
虽然学生们在初中阶段已经学过定语从句，多数能读懂含有简单定语从句的句子，但高中阶段对定语从句运用的能力要求更高，不仅要求学生理解其句法功能，还要求学生能运用定语从句进行书面表达。
要求提高了，难度也随之增加。
英语和汉语中都有定语，英语中的定语从句是汉语中所没有的；而且中英两种语言的句型结构也有着巨大差异。
这就对中国学生理解定语从句造成了一定的障碍。
所以，课前学生必须清晰理解以下知识：1.主语和谓语是英语句子不可或缺的两个部分，除少数句子(如祈使句和感叹句等)外，一句话必须同时具备主语和谓语，所表达的意思才完整；在复合句中，主句和从句各自具有属于自己的独立的主语和谓语。
2.定语的概念：描述见表1。
表1 英语中定语的概念及构成3.英语中有5种简单句的基本句型，它们是构成一切长难句的基础。
表2 英语中5种简单句的基本句型观察例句，引出定语从句的相关概念如果直接把概念化的东西平铺直叙给学生念一遍，语言学习会枯燥而无味，而且很突兀。
这时，例句的展现，引导式的分析就很重要了，如：The students (who do not study hard) will not pass the exam.让学生观察例句，此时在教师的指导下找出主句的主干：The students will not pass the exam，即主谓宾结构。
合并定语从句
合并定语从句合并定语从句引导语：如何合并定语从句呢？接下来是店铺为你带来收集整理的文章，欢迎阅读！任何句子=主干句+从句介词短语和非谓语动词都是从句的省略：I know the man who is in the car.省略为：I know the man in the car.I like girls who have long hair.省略为：I like girls having long hair.何为定?定即限制、划范围。
定语从句只有两种：人(who)和物(which)奥卡姆剃刀：定语从句形成过程的本质就是合并同类项。
人(who)：我认识那个在车里哭的人。
A(主句)：I know the man.B(从句)：The man is crying in the car.合并：I know the man(the man替换为)who is crying in the car.物(which)：我不喜欢没有蕾丝边的衣服。
A(主句)：I don't like clothes.B(从句)：Clothes do not have laces.合并：I don't like clothes(clothes替换为)which do not have laces.大道归一：where,when,whose,why,that附加阅读：定语从句的“前置合译法”在英文当中，定语从句总是在被修饰词后边出现，而中文当中，定语不论长短总在被修饰词之前出现，所以在英译汉时，产生了这种将定语从句前置翻译的方法。
如果你不知道我在说什么，可以关注“门徒protege”公众号，点击“查看历史消息”，回顾往期文章——“玮玮道来之定语从句”。
由此来看，中英文翻译的过程在本质上就是中西方思维转换的过程，只要把握住这个大的方向，就会对各种翻译的方法的产生有更深刻的理解。
下面我们看例句：On the whole，such a conclusion can be drawn with a certain degree of confidence，but only if the child can be assumed to have had the same attitude towards the test as the others with whom he is being compared，and only if he was not punished by lack of relevant information which they possessed.很多人，包括我，第一眼看到这段话的时候，大脑一片混乱，不知从何下手。

英语写作 定语从句
英语写作利器之定语从句要想写出定语从句，首先要保证两个简单句中有重复词汇，再将含有重复词汇的两个简单句合成定语从句。
一．合并法【使用条件】写作要点中要有重复词汇。
（该重复词汇一般是名词或代词，第二次出现可能会用代词代替）【步骤】第一步：把两个句子翻译成英语简单句，并标出重复词汇。
（如出现代词，则把代词换成它替代的名词）E.g.我校将举办一场演讲比赛，它的主题是人与自然__________________________________ ________________________________________. 第二步：确定主句和从句，将从句的重复词汇用对应的关系词替换并提至从句句首。
注意：1. 在确定主句和从句时，需根据中文构思判断合成后的句子主要想表达哪个要点，含有该要点的就是主句。
2.用关系词替换时，如重复词汇前有介词时，用关系副词替换；没有介词时，用关系代词替换。
按照这个步骤，上面的句子哪句是主句？哪句是从句？__________________________________ _________________________________________ 从句的重复词汇为：___________________。
用哪个关系词提到它？______________. 且把关系词提到哪里？____________第三步：将替换后的从句作为整体置于主句重复词后面。
按照该步骤，上面的句子最终可合并为：_________________________________________________________________________. 这样，一个完整的定语从句就出来了。
二．拆分法【使用条件】修饰成分中有主谓短语【步骤】第一步：在中文语境下，把被修饰语拆分到两个完整的句子中去，然后再翻译成英文。
例：这个行李箱（suitcase）是妈妈送个我的生日礼物。
_______________________________________________________________________________ _______________________________________________________________________________ 第二步：确定主句和从句，将从句的重复词汇用对应的关系词替换并提至从句句首。
合并句子学习定语从句
利用句子合并来学习定语从句定语从句两个术语：先行词，关系词先行词：被修饰的名词、名词词组或代词关系词（关系代词或关系副词）：连接先行词与定语从句的词。
关系代词有：who, whom, whose, that, which等；关系副词有：when, where, why等；1、关系词在定语从句中充当主语先行词为人时（1）两个单句为The boys are from Class One. The boys are playing football.（2）第一句为主句，第二句为从句，将两个单句合并为一句。
The boys（the boys are playing football）are from Class One.(3) 括号中句子里的主语the boys, 和先行词是同一个词，应该用关系词替换从句中重复的the boys. The boys 在从句中作主语，关系词中能作主语并代表人的是who, thatThe boys（who\that are playing football）are from Class One.(4) who\that==the boys, 在定语从句中做主语的成分，并连接先行词和定语从句。
先行词为物时（1）I found the letter. The letter came yesterday.（2）I found The letter( the letter came yesterday).（3）用关系词替换从句中重复的the letter, 关系词中能作主语并代表物的是which, thatI found The letter(which\that came yesterday).（4）which\that==the letter, 在定语从句中做主语的成分，并连接先行词和定语从句。
2. 关系词在定语从句中充当宾语先行词为人时（1）The man is my friend. You met the man just now（2）The man (you met the man just now) is my friend.（3）用关系词替换从句中重复的the man, 关系词中能作宾语并代表人的是whom, thatThe man (whom\that you met just now) is my friend.（4）whom\that==the man, 在定语从句中做宾语的成分，并连接先行词和定语从句。
句子合并定语从句
句子合并定语从句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 ago2.He visited the Summer Palace this summer.He went there four years ago3.He lied to his mother.It made her very angry4.I have many books.Some of the books are about English5.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。

2）从形式上看，限制*定语从句与先行词之间没有逗号隔开，而非限制*定语从句与先行词之间有逗号隔开。
请看例句：thegirlwhoiswearingabluenecklaceismary.(限制*)thegirl,whoisalsoastudent,isplantingtreesinthefield.(非限制*) 解析：第一句中的whoiswearingabluenecklace是限制*定语从句，没有逗号，不那去掉，否则意思不完整。
定前必有先行词，名代两类最适宜；例句：1)thereissomebodyherewhowantstospeaktoyou.有人要和你讲话。
2)thosewhowerefortheplanraisedtheirhands.那些赞成计划的举起了手。

句子合并知识点
句子合并知识点句子合并是英语语法中的一个重要知识点，它指的是将两个或多个句子合并成一个更大的句子。
合并句子的目的是提高文章的连贯性和表达的准确性，使文章更加流畅。
本文将介绍句子合并的知识点，包括合并原则、常见的句子合并方法以及一些需要特别注意的情况。
一、合并原则在进行句子合并时，需要遵循以下原则：1. 主谓一致：合并后的句子主语和谓语要保持一致。
例：He plays basketball. He is a sports enthusiast.合并后的句子：He, who is a sports enthusiast, plays basketball.2. 时态一致：合并后的句子的时态要保持一致。
例：She studied hard. She passed the exam.合并后的句子：She studied hard and passed the exam.3. 人称一致：合并后的句子的人称要保持一致。
例：I am a teacher. You are a student.合并后的句子：I, a teacher, and you, a student.二、常见的句子合并方法1. 使用连词合并：常用的连词包括and、but、or、so等。
例：He is a doctor. He is very kind.合并后的句子：He is a doctor and he is very kind.2. 使用非谓语动词合并：非谓语动词包括不定式、动名词和现在分词。
例：They went to the park. They played football.合并后的句子：They went to the park to play football.3. 使用定语从句合并：将两个句子合并成一个主句和一个定语从句。

用合并句子法讲解定语从句定语从句是高中英语教学中重要的语法部分，同时也是为下一步学好其他从句（名词性从句）打好基础。
但在实际英语教学中，学生因为对英语句子成分没有清晰的概念，所以导致对定语从句知其然而不知其所以然。
在教授定语从句时，应先从句子成分入手，使学生先了解什么是定语，然后在利用合并句子的方式解析定语从句是如何构成的，并引出引导词的使用方法。
一、什么是定语句子中修饰名词或代词的成分叫做定语。
定语可以由形容词，名词，不定式，分词，动名词或从句来充当。
eg:I bought an (expensive) computer. （形容词）I met someone( funny) on my way to school. （形容词）（修饰不定代词的定语后置）she is an( English) teacher. （名词）I have a lot of work( to do). （不定式）The book( written by Tom) is very popular now. （过去分词短语）We can see the (rising) sun. （现在分词）= the sun is rising.He is in the( reading) room. (动名词) = the room for readingThe boy (who broke the window)is Tom’s brother. （从句）二、定语从句两个术语：先行词，关系词先行词：被修饰的名词、名词词组或代词关系词（关系代词或关系副词）：连接先行词与定语从句的词。
关系代词有：who, whom, whose, that, which等；关系副词有：when, where, why等；1、关系词在定语从句中充当主语先行词为人时（1）两个单句为The boys are from Class One. The boys are playing football.（2）第一句为主句，第二句为从句，将两个单句合并为一句。
The boys（the boys are playing football）are from Class One.(3) 括号中句子里的主语the boys, 和先行词是同一个词，应该用关系词替换从句中重复的the boys. The boys 在从句中作主语，关系词中能作主语并代表人的是who, thatThe boys（who\that are playing football）are from Class One.(4) who\that==the boys, 在定语从句中做主语的成分，并连接先行词和定语从句。
先行词为物时（1）I found the letter. The letter came yesterday.（2）I found The letter( the letter came yesterday).（3）用关系词替换从句中重复的the letter, 关系词中能作主语并代表物的是which, thatI found The letter(which\that came yesterday).（4）which\that==the letter, 在定语从句中做主语的成分，并连接先行词和定语从句。
