定语从句易混点讲解定语从句要点比较多，命题角度也就有很多，这就注定它必定是高考考查的一个热点。
下面针对定语从句中同学们比较容易忽略或容易混淆的地方给大家做一个归纳，帮助大家更好地掌握定语从句，从而在考试中认清考点，轻松得分。
易混点一：表特制的两种结构This is the school____ you visited.This school is____ you visited.易混点二：关系代词与关系副词的选择不明确（学会拆分句子，注意词性就不会做错）1.I still remember the days _____ we spent together in the middle school.2.I still remember the days ______we studied together in the middle school.A. whatB. whichC. whenD. while解读：定语从句中关系词的选择主要是看先行词在从句中作什么成分：作主语、宾语、表语、补语时一般用关系代词；作状语一般用关系副词。
第1题中先行词the days在从句中作及物动词spent的宾语所以选B；第2题中先行词the days作不及物动词worked的时间状语，所以选C。
易混点三：某些关系代词的特殊用法不明确1.He told me a lot about the dog and its owner _____I met just now in the park.2.He failed the final exams, ____made his parents unhappy.3.He was late for the meeting, _____was the case.A. thatB. asC. whatD. whom解读：关系代词that和which在指物以及关系代词that和who/whom在指人时常常可以互换。

定语从句与十一种句型易混辨析鲁山一高徐焕焕一．定语从句与并列句① He has many friends, none of whom say he is greedy.② He has many friends, but none of them say he is greedy.定语从句与主句之间是一种主从关系，需关系词将两者连接，如句①，故填whom ；并列句是由并列连词等连接起来的句子，此时不再需要关系词了，如句②，故填代词them.二．定语从句与强调句①It was in Wuhan that Jill met the girl and adopted her.②It was in Wuhan where Jill met the girl and adopted her.强调句型的结构式: “ It is／was＋被强调部分＋that 从句”判断是不是强调句标准是：先把It is／was… that去掉，剩下的句子如果仍然成立，则为强调句型，如句①，故填that，否则为定语从句，如句②，故填where.三．定语从句与强调句在特定语境中的区分----Where did you meet him?-----It was in the factory B he worked.A. thatB. where从语法结构上分析，A 、B两个选项都合适，填 A ，是强调句型，填 B ，是定语从句；但是结合语境，填A句意为“他是在这个工厂工作的，”答非所问，而填B句意为“是在他工作的工厂里，”符合语境，故正确答案只能是B.四．定语从句与结果状语从句① I want to have the same dictionary as he has.② She is such a kind teacher that all of us respect her.如果as, that在引导的从句中充当一定成分，则它们引导的是定语从句，如句①, 故填as ；相反，如果它们只起连接作用，则它们引导的是结果状语从句，如句②，故填that.五．定语从句与地点状语从句①We should go to the place where／in which we are needed most.②We should go where we are needed most.where引导定语从句，其前一定要有表地点的先行词，而且可以用“介词＋which”替代where ，如句①, “place”做先行词，故填where／in which ；而地点状语从句前无先行词，只能用where引导地点状语从句，如句②，故填where.六．定语从句与固定句型①It was the time when the two countries were at war.②It was the first time that she had ever left her motherland.句①中time是先行词，其后是when引导的定语从句；句②是固定句型：It ＋is／was＋序数词＋time＋that从句.七．定语从句与两个简单句①I found a note on the table, which read: “I’ve left for Harbin.”②I found a note on the table. It read: “I’ve left for Harbin.”含有定语从句的复合句，有主句，有从句，即定语从句，必须要有关系词，如句①；而两个简单句是两个独立的完整的句子，不需要关系词，如句②。
定语从句易错易混点易错点一：关系代词和关系副词的混用。
例 1. I’ll never forget the days when I spent in New York with you. 例 2. I’ll never forget the days which I visited New York with you. 析：例 1 中的 when 应改为 which 或 that ;例 2 中的 which 应改为 when .区分关系代词和关系副词的关键是看它们在定语从句中所充当的成分。
如果定语从句中缺少主语、宾语，就应考虑使用关系代词，如例 1 ;若定语从句中缺少状语，就应考虑使用关系副词，如例 2 .易错点二：固定句式出差错。
例 3. Mary is so lovely a girl as everybody loves her. 例 4. Mary is so lovely a girl that everybody loves. 析：例 3 中的 as 应改为that ;例 4 中的 that 应改为 as . so…as 或 so…that 为固定句式，前者为 as 引导的定语从句， as 在定语从句中作宾语或主语，如例 4 ;后者为 that 引导的结果状语从句，该从句的成分是完整的，不缺少主语或宾语，如例 3 .类似的固定句式还有 the same… as (that) ， such…as ， as…as 等。
易错点三：主谓不一致。
例 5. Tom is one of the students who likes swimming. 例6. Tom is the only one of the students who like swimming. 析：例 5 中的 likes 应改为 like ;例 6 中的 like 应改为 likes .在“ one of + 复数名词 + 定语从句”结构中，定语从句的先行词是复数名词，故谓语动词要用复数形式，如例 5 ;在“ the (only) one of + 复数名词 + 定语从句”结构中，先行词是 one ，而不是复数名词，故谓语动词要用单数形式，如例 6 .易错点四：与强调句型及其他句型的混合。

定语从句与六种易混句型巧区分一、定语从句是高中阶段的重点语法项目之一。
因此，同学们有必要全面弄清其用法。
定语从句从句型上讲，它与六种句式相似，十分容易混淆。
为了帮助同学们分清定语从句与这六种句型的差异，现将其分类例析如下。
一、定语从句与并列句1．用一个恰当的词完成下列句子，使之完整与正确。
①Mr Li has three daughters，none of _____ is an engineer．②Mr Li has three daughters，but none of _____ is a dancer．③Mr Li has three daughters； _____ are doctors．定语从句与并列句的主要区别在于：并列句有像and，but，so等并列连词或两个句子用分号连接，这时就不能再用引导定语从句的关系词了。
二、定语从句与地点状语从句1.用一个恰当的词完成下列句子，使之完整与正确。
①Rice doesn't grow well _____ there is not enough water．②I still remember the farm _____ my parents worked ten years ago．定语从句与地点状语从句的主要区别在于：定语从句有表示地点的先行词，而地点状语从句则没有；定语从句的关系词根据需要可用“介词＋which”来代替where，而地点状语从句则通常只能由 where引导。
三、定语从句与强调句1．用一个恰当的词完成下列句子，使之完整与正确。
①It is on the morning of May 1st __ I met Liang Wei at the airport．②It is the factory ___ Mr Wang works．强调句与定语从句的区别【原题复现】27.It was from only a few supplies that she had bought in the village_____the hostes s cooked such a nice dinner.A. where B．that C．when D. which【语法补漏】强调句与定语从句的区别是：在定语从句中一般使用关系代词that, which，who, whom或关系副词when, where，why等,先行词(中心词)一般是名词或名词短语，而在强调句中，可以用副词、介词短语或从句来作被强调的内容。

【分析】关系代词在定语从句中作主语、宾语、表语、定语。
关系代词在从句中作主语时，从句谓语动词的形式要与先行词保持一致。
关系副词代替表示时间、地点、原因的先行词，并在定语从句中作时间、地点和原因状语。
易错陷阱2：that与which易混易错点。
【分析】易错陷阱3：介词+关系词易混易错点。
【分析】1.介词的选择需要根据动词、形容词、介词短语的搭配或者句中所表达的逻辑意思而决定。
2.先行词指人时，关系代词用whom;先行词指物时，关系代词用which；且不可省略。
易错陷阱4：whose易混易错点。
【分析】whose既可以指人，也可以指物，在从句中作定语，修饰名词。
whose+n.=the+n.+of which/whom易错陷阱5：that引导定语从句与同位语从句易混易错点。
【分析】that在定语从句中担任成分，在同位语从句中不做成分。
【易错点提醒一】关系代词和关系副词易混易错点【例1】（2024届浙江省强基联盟高三仿真模拟卷）There is a saying among the archaeological circles in China_________goes,“A page from a book of the Song Dynasty is worth a tael of gold”.【答案】that/which【解析】考查定语从句。
句意：中国考古界有一句俗语，“一页宋版，一两黄金”，指的是这些古籍的重要性和很高的价值。
分析句子可知，空处引导限制性定语从句，修饰先行词saying，先行词指物，在从句中作主语，应用关系代词that或which作引导词。
定语从句易错、易混点实例解析作者：邹玉芳来源：《科学导报·学术》2019年第33期摘 ;要：定语从句是英语语法中的重要组成部分，在高考中所占比例很大，无论单选，改错，还是阅读中，学生在理解中有难度。
笔者从学生易错易混淆的知识点入手，对难点进行针对性的深入对比及分析。
关键词：定语从句;实例;解析全国高考英语卷对三大从句（定语从句、名词性从句和状语从句）的考查一直以来都占了相当大的比例。
这三类从句按其作用又可以分为成为：形容词性从句、名词性从句和副词性从句。
高考对这类复合句的考查的形式不仅体现在语法填空和改错中，还会渗透在每篇文章的长难句中，因此掌握这三大从句的使用至关重要。
但是，由于受汉语思维的影响，学生们在平日学习过程中，依然不能十分准确地理解，掌握和使用这三大从句。
尤其是定语从句，作为三大从句的重中之重。
因此，笔者针对这一情况归纳总结了定语从句高频考点及学生容易出错的典型例句，以强化学生对这一重点知识的理解和掌握。
易混考点一：关系代词与关系副词1.I will never forget the day______I met you.（填关系副词when，先行词the day在定语从句作状语）2.I will never forget the day______we spent together.（填关系代词that或which，先行词the day 在定语从句中作宾语）总结：定语从句中的引导词分为关系代词与关系副词。
基本判断依据为：当定语从句缺少主语或宾语时，选用关系代词;当定语从句主谓宾齐全时，选用关系副词。
例：1.Is this the factory______ you visited the other day？（填that或which）2.Is this the factory______ your father once worked？（填where）3.This film brought the days back to me_____ I was taken good care of in that far-away village.（填when）4.This film brought the days back to me_____ I had spent with my good friends in that far-away village.（填that或which）易混考点二：定语从句与并列句1.He has written two novels，both of ___ has been translated into English.（填which，此句不含连词，which关系代词指代two novels）2.He has written two novels，and both of ___ has been translated into English.（填them，此句为and连接的并列句）总结：关键在于先判断是并列句还是复合句。
定语从句是高中英语教学的重点、难点,也是历年高考的热点。
为便于同学们学习掌握该内容,本文拟从结构入手比较定语从句与其易混句型。
主要体现在以下几个方面:一、定语从句与并列句的判断1.I have tw o close friends and both of ________are doctors.2.I have tw o close friends,both of ________are doctors.A.whoB.w ho mC.themD.w hich解析:解答此类试题时一定要注意标点符号和并列连词的使用。
and,but,so,or 等只连接两个独立分句而构成并列句。
没有and,but,so,or 等为非限制性定语从句。
正确答案为:1.C 2.B二、定语从句与状语从句的判断A.定语从句与地点状语从句He adv ised me to live in the place ________the air is fresher.A.in w hereB.in whichC.the place w hereD.w here解析:从句前有无先行词是判断定语从句与地点状语从句的重要标志。
这个句子有先行词the place ,所以是定语从句,因此B 和D 均对,改成He adv ised me to live________the air is fresher ,那才是地点状语从句,只能选D.w here 。
B.定语从句与结果状语从句His plan was such a go od one ________we all agreed to accept it.A.soB.andC.thatD.as解析:从句中的成分是否完整是区别这两类从句的重要标志。
该句中的成分完整因此是such …that …引导的状语从句,that 在从句中不担任成分,从句中有宾语it 。
如果从句中无it,则为定语从句,因先行词被such 修饰,所以关系代词用as 。
定语从句与其它易混句型1.定语从句与并列句1). a. I saw some trees, and the leaves of _______were black with diseases.b. I saw some trees, the leaves of ______were black with disease.2). a. The professor is a little man, on the nose of ______there is a pair of glasses.b. The professor is a little man, and on the nose of ______there is a pair of glasses.解题点拨：是否有连词是区分定语从句和并列句的关键。
2.定语从句和状语从句(1)This is such a big stone _______no one can lift it.This is such a big stone _______no one can lift.Tom is not such an intelligent person _____you think.They had such a fierce dog _____ no one dared to go near their house.分析：（1）句从引导词来看，状语从句中的that 是连词，在从句中不充当任何成分，而定语从句中的as在从句中要作一个成分（主语，宾语或表语）。
3.定语从句和强调句(1) It is in this room ______I lived last year. It is the room _______I lived last year.(2) It was at seven o’clock ________he went to school this morning.It was seven o’clock _______he went to school this morning.分析：强调句句型：It is/was +被强调的成份+that/who +其它部分去掉It is/was….that/who…,句子照样成立。
高中英语定语从句—与从句易混点精讲精练定语从句使用时的常见错误:(1)能否正确使用关系代词或关系副词是写好定语从句的关键。
用关系代词还是关系副词，完全取决于其在从句中作什么成分。
①This is the mountain village where I visited last year. (×)②This is t he mountain village which I visited last year.(√)解析：which 作为关系代词,指代先行词, 并在从句中充当了宾语。
visit the mountain village (which)(2)无论是关系代词还是关系副词，都在定语从句中充当成分，都有替代作用，而被替代部分需去掉。
①Is this the bike (that) you bought it yesterday? (×)②Is this the bike (that) you bought yesterday？(√)解析：关系代词that 已经代替the bike 做了从句动词bought 的宾语，it 为累赘。
(3) whose既可指人又可指物，在定语从句中作定语。
指物时，“whose＋名词”可用“the＋名词＋of which”或“of which＋the＋名词”来代替。
①Do you know the boy whose handwriting is very beautiful?你认识那个书法非常漂亮的男孩吗？②This is the house whose window broke last night.＝This is the house, the window of which broke last night.＝This is the house, of which the window broke last night.这就是昨晚窗户被打破的那所房子。
