新人教版定语从句说课稿
新人教版定语从句说课稿尊敬的各位评委、老师，大家好！今天，我将为大家说课新人教版高中英语教材中的定语从句单元。
在开始之前，让我们先来明确一下本单元的教学目标和重点内容。
教学目标：1. 让学生掌握定语从句的基本结构和用法。
2. 培养学生通过上下文理解定语从句的能力。
3. 提高学生运用定语从句进行准确表达的能力。
4. 通过实际语境的练习，加强学生对定语从句的理解和应用。
教学重点：1. 定语从句的引导词及其功能。
2. 定语从句与先行词之间的关系。
3. 定语从句在句子中的位置及其对句子意义的影响。
接下来，我将从以下几个方面展开我的说课内容：一、导入新课在课程开始阶段，我会通过提问和展示图片的方式，引导学生回顾之前学过的从句知识，并自然过渡到定语从句的概念。
例如，我会展示一张含有多个物品的图片，并询问学生：“Which one do you prefer?” 这样的问题不仅能够引起学生的兴趣，还能够让学生意识到在描述特定事物时，定语从句的重要性。
二、呈现新知在这一部分，我会通过PPT展示和板书的方式，向学生介绍定语从句的基本结构。
首先，我会解释什么是定语从句，它是用来修饰名词或代词的从句。
然后，我会通过例句展示定语从句的两种基本形式：限制性定语从句和非限制性定语从句，并强调它们的区别和用法。
三、讲解与练习在讲解了定语从句的基本结构之后，我会通过一系列的练习来巩固学生的理解。
这些练习包括填空题、选择题和改错题，旨在帮助学生掌握定语从句的引导词及其在句子中的正确位置。
同时，我会引导学生分析句子结构，理解定语从句与先行词之间的关系。
四、实际应用为了让学生更好地将所学知识运用到实际中，我会设计一些情景对话和写作任务。
在情景对话中，学生需要运用定语从句来描述人物、物品或事件。
在写作任务中，学生将被要求写一篇短文，其中必须包含多个定语从句。
通过这些活动，学生能够在真实语境中练习和加深对定语从句的理解和运用。
五、总结与反馈在课程的最后，我会带领学生一起回顾本节课的重点内容，并进行知识点的总结。

定语从句【考点扫描】中考对定语从句的考查主要集中在以下几个方面：1．定语从句的功用和结构2．关系代词和关系副词的功用3．各个关系代词和关系副词的具体用法考查的主要形式是单项填空、完型填空、短文填空和完成句子。
阅读理解和书面表达肯定也要用到定语从句。
【名师精讲】一. 定语从句的功用和结构在复合句中，修饰某一名词或代词的从句叫做定语从句。
被定从句修饰的词叫做先行词。
定语从句必须放在先行词之后。
引导定语从句的关联词有关系代词和关系副词。
例如：This is the present that he gave me for my birthday.Do you know everybody who came to the party?I still remember the night when I first came to the village?This is the place where Chairman Mao once lived.二. 关系代词和关系副词的功用关系代词和关系副词用来引导定于从句，在先行词和定语从句之间起纽带作用，使二者联系起来。
关系代词和关系副词又在定语从句中充当一个成分。
关系待客做主语，宾语，定语，关系副词可作状语。
1. 作主语：关系代词在定语从句中作主语时，从句的谓语动词的人称和数须和先行词一致。
例如：I don’t like people who talk much but do little.The cars which are produced in Hubei Province sell very well.2. 作宾语：She is the person that I met at the school gate yesterday.The book that my grandmother gave me is called “The Great Escape”.3. 作定语关系代词whose在定语从句中作定语用。

2) This is the pen (which) he bought yesterday. 4. that指人时，相当于who或者whom； 做宾语
指物时，相当于which。
在宾语从句中做主语或者宾语，做宾语时可省略。
1) The people _th__a_t_/_w__h_o_come to visit the city are
The girl is Mary. We saw her yesterday. The girl that / who we saw yesterday is Mary.
合并句子:
1. The man is a farmer.
2. The man is speaking at the meeting.
注意：当先行词指人时，偶尔也可用关系代who， 如： 1) Any man t_h_a__t_/__w_h__ohas a sense of duty won’t
do such a thing. 任何有责任感的人都不会做这样的事。
2)All the guests__th__a_t_/__w__h_owere invited to her wedding were important people.
5．当先行词前面有who, which等疑问代词时。如： 1)Who is the man_t_h__a_t is standing by the gate? 站在门口的那个人是谁？ 2)Which is the T-shirt _t_h__a_t_ fits me most? 哪件T恤衫最合我的身？ 6．当先行词为人与物时。如：
4．当先行词被the very, the only , the last修饰时。
1)This is the very dictionary _th__a_t_ I want to buy. 这正是我要买的词典。

高中英语人教版必修2 Unit2 定语从句讲解
定语从句一、定语从句1．定语从句三步：第一找出先行词；第二看先行词在定语从句中的语法功能（做主语、宾语或状语）；第三选择合适的关联词。
2．定语从句在选择关联词that 与which时，常常容易出错，所以应记住什么时候只能用that，什么时候只能用which.（1）．只能用that 的情况归纳4种：即先得词被序数词最高级修饰过；先行词为all 、everything、nothing等不定代词；先行词同时是人和物并列时；最后先行词分别被the only 、the very the same、the last 修饰。
请看下列四组例句，注意其先行词：①．The first thing that we should do is to work out a plan.②．I t almost seemed as if the good man were trying to teach us all that heknew at this lesson.③．Later my father and Mr. Crosset talked for about half a four of thingsand persons that they remembered in school.④．This is the very dictionary that I want to find.（2）．只用which is 情况有两种情况：一是非限制性定语从句，关联词要用which；二是做介词宾语时只能用which。
请看下列两组例句：I said nothing, which made him more angry.I have the book about which you are talking.三、在定语从句的非限制性定语中，which 和as 是容易混淆的。
在很多情况下两者兼可互换，但在下列情况中不可互换：1、通常As可以放在整句的句首，而which，只能在逗号之后，as 本身含有“正如”，as 在定语从句中既可是主语也可做宾语。

定从的分类
是指先行词在意义上不可缺少的定语。如果去掉，主句的意思就不完整或者失去意义。这种从句和主句关系十分密切，写时不用逗号分开。
非限制性定语从句和主句关系不很密切，只是对先行词做些附加说明。如果去掉，主句的意思仍然清楚。这种从句，写时往往用逗号隔开。
