初三英语Unit 17 Lesson 68说课稿

一、教材分析：
Lesson 68是第十七单元的第四课时，是一节复习课。Unit
17主要围绕着寻找“丢失的项链”这一话题展开，通过学习定语从句，培养学生运用所学语言描述人和物的特征。Lesson 68
所安排的听说读写活动都围绕着侦破案件展开，旨在通过一系列的活动和练习，加深巩固学生对定语从句的理解和运用，并实现准确地描述人物外貌特征，撰写案件报告的教学目的。
二、教学目标及重、难点：
（一） 知识目标：
1、复习巩固定语从句的用法。
2、学习掌握单词conversation, robbery, description.
（二） 能力目标：培养学生运用所学语言描述人物外貌特征的能力。
（三） 技能目标：能根据线索写出案情报告及通缉令。
（四） 教学重点：用于描述人物特征的定语从句。
（五） 教学难点：学会分析并对现有的信息进行处理，产生正确的判断，并写出案情报告。
三、教学活动设计：
Main task: The students are able to describe the characteristic of a
person.
Step one: Warming-up
“Guessing game” 展示一幅图画。让学生通过猜测“Is the man who
…?”判断图中的人物分别是谁。这一活动既是热身，又是一个练习使用定语从句的活动。主要目的是复习定语从句的用法，同时也让学生熟悉如何描述人物特征。（3-4分钟）
Step two: Pre-task
“To be a
detective”进行一个考眼力的游戏，首先放一张图片，让学生仔细观察，之后放另一张图片，请学生判断两张图的区别，谁是受害者（教victim）,谁是小偷。请他们分析理由。这一活动除了复习定语从句以外，也是引出本课的话题：辨认嫌疑犯（5分钟）
Step three: While-task
“Who’s the robber?” 进行一个听力练习（SB Lesson 68 Part
2）。听录音，判断四个人物中谁是强盗。（3分钟）
“Write a report”假设你是警察，根据上面听到的这段描述，完成一份案情报告(SB Lesson 68 Part
5)。在课内校对答案。（5-8分钟）
Step four: Post-task
先让学生完成一个警察与受害人之间的对话（Workbook, Ex 2）
在此基础上进行“Dialogue making”。
向学生介绍一个案件，请他们根据所给的信息编写一个警察与受害者之间的对话（可参照课后练习2）并选择几组进行对话表演。（8-12分钟）
假设你是警察，根据案件信息写一个通缉令（也可自己想象一个案件）。并选择几份在课内点评。（8-13分钟）
Step five: Homework
完成练习册中的练习。在课外阅读有关的著名的侦探小说，并挑选一则在班上交流。
四、评估与反馈：
学生能否熟练运用定语从句进行描述或判断人物的外貌特征是判断本节课是否达到教学目的的一个重要标准。
Teaching Process:
Step One Warming-up
1. Play a guessing game to review the Attributive Clause. Looking at
the picture, Teacher asks “Can you guess who is Mr. Smith?” Students
may answer like this: “Is he the man who is fishing?”
2. Show another picture of a bus. Tell them “One night, there are
some passengers on the bus, some are sitting and sleeping, some are
standing and looking out of the window. Please look carefully, try
to remember what they’re wearing.” Suddenly the light on the bus is
out. It ‘s dark. And something has happened. Now look at the picture 
carefully, can you find out whose things have been stolen? Who is
the victim? (Explain the word) And who ito discuss with the partners. Check the
answer.
Step Two Presentation
Teacher says: “Last Thursday there was a robbery. Miss Brown is the
victim. She was robbed by a man. Now the police have found four
suspects. Would you please listen tothetape carefully and find out
who is the robber？” Play the tape, check the answer.
Since the police have caught the robber, they should write a police
report about the robbery. Please help the police finish the report.
(Students’ book Part 5) Check the answers and read it.
Step Three Practice
1. Ask the students to finish a dialogue between a policeman and a
victim and read it out.
2. Give the students some information about another robbery, ask
them to make a new dialogue just like the above one. And act it out.
3. Suppose you are the police, and you want to catch the robber with
the help of the public. You need to write a WANTED. Let them work in
pairs and write a WANTED, they can either use the information of the
above one, or just use their own opinions. Shoe some of the work to
class.
