2023年中考英语语法定语从句考点归纳及易错陷阱
2023年中考英语语法定语从句考点归纳及易错陷阱一、概述所谓定语从句，就是指在主从复合句用作定语的从句。
定语从句通常修饰名词或代词，对它进行限制、描绘和说明。
受定语从句修饰的词语叫先行词，引导定语从句的词语叫关系词。
关系词按其性质又分关系代词和关系副词。
关系词不仅引导定语从句，同时还在定语从句充当一定的句子成分:The girl who spoke is my best friend. 进话的姑娘是我最好的朋友。
此句中，who spoke是由关系代词who引导的定语从句，用以修饰先行词the girl，同时who 在定语从句中用作主语.This is the town where l was born.这就是我出生的城市。
此句中，where l was born是由关系副词where引导的定语从句，用以修饰先行词the town，同时where在定语从句中用作状语。
二、考点归纳考点1 考查关系代词的判断与用法在初中英语中，应该掌握的关系代词不多，主要有that,who.whom,whose,which，其中who和whom只用于指人，which 只用于指事物，whose和 hat既可于指人也可用于指物。
各个关系代词在定语从句中的用法是:that可用作主语或宾语，who用作主语，whom用作宾语，whose用作定语，which用作主语或宾语。
选用关系代词有两个技巧:一看先行词的意义:指人用who.whom,whose,that; 指物用which,that, whose。
二看关系词的句法功能:作主语用that which,who等; 作宾语用whom,that, which等A plane is a machine that can fly.飞机是一种能飞行的机器。
(that指物，在从句中用作主语)The man who lives in that house is my uncle.住在那座房子里的人是我叔叔。

定语从句十大易错点
例析定语从句十大易错点定语从句是中学英语教学中的一个重要语法项目，也是历届高考的热点所在。
笔者现将定语从句易出错的地方归纳为以下几点，希望对大家有所帮助。
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例7. Was it in the shop that you bought the recorder that you lost your pen？例8. You’d better make a mark at where you have any questions.析：例7 中第一个that 应改为where ；例8 中应去掉at .例7 为带有定语从句的强调句，you bought the recorder 为定语从句，其引导词应用where ，后面第二个that 才是强调句中的that ，此句可还原为：You lost your pen in the shop where you bought the recorder .例8 为where 引导的地点状语从句。

考查定语从句关系代词辨析。
who 谁，指人并在从句中作主语的关系代词；that 无实际意义，即可指人也可指物的关系代词；where 表地点的关系副词；when 表时间的关系副词。
根据句子结构，是一个定语从句。
先行词是movie，指物，在从句中作宾语，所以用关系代词that。
故选B。
【点睛】定语从句中关系词的判断。
首先看从句中缺少的成分，如果缺时间状语或地点状语，就用关系副词when或where；如果缺宾语或主语，就用关系代词。
先行词指人，并在从句中作主语，就用关系代词who或that；先行词指物，并在从句中作主语或宾语，就用关系代词that。
2．C解析：C【解析】句意：雪莉是教会我如何使用微信的一个女孩。
whom修饰人，在定语从句中作宾语或表语；which修饰事物，在定语从句中主语或宾语，或表语。
who修饰人，在定语从句作主语，宾语或表语。
此处作为定语从句的主语，修饰the girl，故用who。
故选C。
3．B解析：B【解析】【详解】句意：——你去过长城了吗？——当然，我认为这是我去过最棒的地方。
考查关系代词。
A. where关系副词；B. that关系代词；C. which关系代词。
此处引导一个定语从句，修饰其前先行词place；关系词在从句中充当宾语，所以用关系代词，排除A；先行词被最高级修饰，所以关系代词只用that，故选B。
4．D解析：D【解析】【分析】【详解】本题考查：定语从句。
选项分析：which做定语从句的关系代词时指代前面的物； that 做关系代词时既可指人也可指物，who做关系代词时，指人。
whom指人，但需在从句中做宾语成分。
综合分析前后文及答案选项，依据前面的everybody可知后面用who作为关系代词，可知此处填who最合适，其中I don't know the one you had a long talk with.中the one 是talk with的宾语，此处可用whom引导，也可以省略关系代词。
完整句意为：—Do you know everybody who came to the party? —I'm afraid not. I don't know the one you had a long talk with.—你认识所有来参加聚会的人吗?—恐怕不是。
我不认识那个和你谈了很久的人。
正确答案为：D【点睛】which与that两者都可指物，常可互换。
其区别主要在于：引导非限制性定语从句时，通常要用which。
如：She received an invitation from her boss, which came as a surprise. 她收到了老板的邀请，这是她意想不到的。
直接放在介词后作宾语时，通常要用which。
先行词有the very, the only, the same 等修饰时，通常用that。
如：This is the only example that I know. 我知道的例子只有这一个。
Those are the very words that he used. 那是他的原话。
