师徒汇报课（师父：张方

徒弟：孙宇培）

第一单元语法——定语从句（限制性定语从句与非限制性定语从句）

Grammar: The Restrictive and Non-Restrictive Attributive Clause Teaching goals教学目标

1). Ability goals能力目标

本节内容定语从句是这学期第三节关于定语从句的内容。通过定语从句的学习可以帮助学生克服高考完型填空和阅读理解题型中长难句的理解困难，同时可以帮助学生在高二高三的书面表达里写含有定语从句的句子，从而使学生的英语作文得高分，完成高中新课改的能力考察目标。

2). Learning ability goals学能目标

1.

本节课让学生接触大量含有定语从句的语言材料，通过学生的思考，通过小组讨论，让学生去观察，发现，提取和加工，进而从中总结归纳出语法规则，这种方法能推动学生主动参与，有利于学生观察、分析、判断和总结等思维能力的提高，有利于学生自主学习能力的提高。

2.

通过本节课的学习，是学生能较好地运用定语从句，能正确认出，勾出，写对包含定语从句的复合句

3)Emotion:情感目标

通过对各种英语文本的学习，调动学习积极性，使学生体会到英语的趣味和实用性

Teaching important points教学重点

1. 限制性定语从句和非限制性定语从句的区别: 提醒学生从句子的意义和形式方面进行比较，发现两种定语从句的不同点。

2. 教师提醒学生可以从意义和形式等方面比较两种定语从句。

Teaching important points教学难点

1. 教师引导学生对这些结论进行归纳分析，结合例句梳理两种定语从句的不同用法。

1). 学生的水平参差不齐，有的学生基础不牢，再加上语法的学习基本以呈现理论为主在辅以练习，内容枯燥，学生兴趣不够，容易分散注意力。尤其在as和while的选择上学生的接受程度不同。

Teaching methods教学方法

1). Analytic approach 2). Have a discussion. (group work) 3). Deductive learning

4). Heuristic method of teaching

Teaching aids教学设备

Teaching procedures 教学过程

Step1 Revision 12mins Task1 定语从句的概念

回顾定语从句的定义：定语从句的定义：在复合句中，修饰某一名词或代词用作定语的从句叫做定语从句。被定语从句修饰的词叫___________，其中连接先行词与从句的词叫____________。

注意：关系词代替先行词并在从句中充当一定的成分。

Task2 定语从句三要素

老师引导学生说出定语从句三要素：1. 先行词2. 关系词3.关系词在从句中所充当的成分

Task3 教师先给出四个小练习让学生回顾定语从句的语法，再通过这几个小题总结出做题规律

1. The student _____ answered the question was Lily. 2. This is the pen ______ he bought yesterday. 3. The man______you met just now is my friend. 4. This is the house _______ he once lived. 做题规律：

第一步：先找出先行词

第二步：看关系词在从句中所充当的成分,如果关系词在句中充当主，宾，表，定，则考虑___________，如果关系词在句中充当状语（如时间状语，地点状语，原因状语），则考虑___________。

第三步：再看先行词指的是什么（人？物？），从而最终确定关系词

Exercise1 学生先做练习，老师抽问学生用做题规律来回答问题

1. I will never forget the day____ we spent in the old town. 2. The shop _____ sells flowers is at the end of the street.

3. I really like the photo of my family _____ my sister took in the city park last year.

4. Harry is the boy _______mother is our English teacher. 5. The foreigner ______visited our school yesterday is from Canada. 6. I'll never forget the days ______I played with you. 7. I'll never forget the days ______I spent with my teacher.

Exercise2 一些特例题型的练习

注意：判断定语从句不能只看先行词，尤其当先行词为时间，地点，原因一类的词时，一定要认真判断。

1.

This is the museum _____ the exhibition was held. 2.

This is the museum _____ you visited a few days ago?

单句改错

1. This is the mountain village where I visited last year.

2. I will never forget the days when I spent in the countryside. 3. I still remember the time which I was in college.

（教学目标Teaching goals: 复习和掌握定语从句中关系代词和关系副词的作用和功能，能准确选择定语从句所需的关系代词或关系副词）

Step2 本课重点

15mins 根据主句和从句的紧密程度，定语从句又分为限制性定语从句和非限制性定语从句。教师给出两句话让学生讨论二者的不同之处：

1.His mother, whom he loved deeply, died ten years ago. 2. People who take physical exercise live longer.

二者的区别：限制性定语从句对先行词起修饰限制作用，如果去掉，就会使句意不完整或概念不清楚；而非限制性定语从句是对先行词起补充说明作用，如果省略，句意仍然清楚、完整。非限制性定语从句中，先行词与定语从句往往有_______隔开,翻译时常译成并列的分句。（教师给出大部分定义，让学生自己完善，鼓励学生自我发现规律）

Task1 语境感知

1. Beijing, which is the capital of China, is a very beautiful city. 2. The boy, whose father is an engineer, studies very hard. 3. The engineer, whom I met in the office，worked very hard．

4. I visited the factory last month, where my brother are working.

5. This is my hometown, where people are friendly. 6. We will put off the outing until next week,when we won't be so busy. 想让学生以小组形式讨论这几句，然后教师引导学生说出限制性和非限制性定语从句中关系词如何让选择，下一步，教师给出完整的规律，让学生反复诵读。

1.

在修饰物时用which而不能用that。总之，非限制性定语从句里没有that。

2.

在非限制定语从句中所有关系词均不可省略

3.

*重点*不是只有which才能引导非限制定语从句。使用非限制性定语从句时，如果先行词指人，可以用________,_______或_________来引导;先行词指物，可以用_______或whose来引导，先行词表时间或地点,可用when,where来引导（它们在从句中作时间状语和地点状语）。

Exercise3 1. The house, ___________we bought last month, is very nice.

2. His daughter, _________is in Beijing now, is coming home next week.

3. He changed his mind, _______ made me very angry.

4. I shall never forget those years _______ I lived on the farm with the farmers, _______ has a great effect on my life.

5. He is working hard, ______will make him pass the final exam.

6. The letter is from my sister, ______is working in Beijing.

7. I love Hami, ________ I was born.

Step3 非限制性定语从句中as和while的区别：5mins which 与 as 引导定语从句都可以指代主句整个一句话。

区别: ①

位置： as引导从句位置比较灵活 可前，中，后；

而which只能放在先行词_____面

，非限制性定语从句在句首时，只能用______引导

②

意思： as正如...，正像...; which这一点,这件事 ③

搭配：前面有the same , such，as时，引导定语从句的关系代词用as，不用which。

教师就这三方面展开说明：

as引导的非限定性定语从句，指代整个主句的内容，但不同于which的是，它引导的定语从句既可以位于主句的前面，也可以位于主句的后面。它的意思是“正如”，在这些从句中as作主语或宾语。

1. As we all know, china is a developing country. (在句首只能使用as) 2. As is known to all, he is the best student in our class. 3. As was expected, he failed in the exam. As anybody can see,

they were telling a lie. 补充词组：

as I can remember 正如我所记得的 as often happens 正如经常发生的那样

as we expect 正如我们预料的那样

as has been said above 如上所述as is often the case 像常规那样 教师给两分钟反复背诵这些as的固定搭配

as引导限定性定语从句，常用于以下句式，其中关系代词在从句中担当主，宾，表语： ① so/as/such+名词+as…像……一样的，像……之类 :

These houses are sold at such a low price as people expected.

This book is not such as I expect. ② the same +名词+as 和……同样的 :1. This is the same book _____ I lost.这本书和我丢的那本一模一样。(定语从句) 2. This is the same book ______ I lost.这本书就是我丢的那本。(定语从句)
