教学设计方案Lesson 33

一、Teaching Aims
　　1. Help Ss understand the general ideas and some details in the dialogue
　　2. Practice in pairs on making a new dialogue about something they are about to buy
　　3. Teach them how to use some of the words and expressions in the dialogue
二、Teaching procedures
Step I Warming Up
　　1. Give a student 5 minutes to have his/her own free talk about anything he/she enjoys
　　2. Encourage Ss to ask the student questions about his/her free talk
　　3. Ask Ss how many of them have got a computer at home
　　4. Ask those who have computers what kind of computers they are using
　　5. Write down “486, 586, desktop, laptop, PC, Mac, Gameboy” on the blackboard

Step II Listening
　　1. Play tape of Lesson 33 twice and ask them to listen to the tape without looking at their books
　　2. Give Ss question before they listen and ask them to try to understand the dialogue with those questions
　　1) How many people are there in the dialogue?
　　2) What are they talking about?
　　3) Do they finally agree with each other?
　　3. Ask three students to answer the questions above

Step III Reading
　　1. Ask Ss one by one questions about the dialogue:
　　1) What did Jenny probably ask Mei Ge to do before they have the dialogue? (to find out the price for the IBM PC 486)
　　2) What does Jenny prefer to buy, PC 486 or PC 586? Why? (see book for the answer)
　　3) Why does Mei Ge want to buy the smaller one?
　　4) Why can’t they waste any more time? (price may go up and the factory needs the computers badly)
　　5) What is their final decision? (not mentioned)
　　2. Ask the next student to correct the mistakes if any
　　3. Give Ss one minute or two to go over the dialogue again and then ask one of the students to be Jenny and tell the others what has happened in the dialogue
One possible answer:
　　I am Jenny and I am working with Mei Ge in a factory. Our factory planned to buy a new computer so Mei Ge and I talked about buying a new computer. I asked Mei Ge to find out the price of the IBM PC 486 but I want to buy the IBM PC 586 because it is better and bigger. What’s more, we will change the 486 for 586 in a few years’ time. But Mei Ge still prefers the smaller one because he thinks it is a waste of money to buy a very good one. He believes PC 486 is good enough. We will meet again to make a decision the next day.
　　4. Ask another student to be Mei Ge and tell the others what has happened

Step IV Teaching
　　1. Teaching Ss the use of different words and expressions
　　2. Ask Ss to repeat the sentences which the teacher gives and after that ask them to make some new sentences with the words and expressions

Step V Practice
　　1. Ask students to use the words and expressions to make a new dialogue
　　2. Ask other students to find out the mistakes

Step VI Summary
　　Ask one of the Ss to tell other Ss what they have learned and write them down on the blackboard

Step VII Homework
　　1. Ask Ss to be the manager of the factory and make up a new dialogue
One possible answer:
　　M (Manager): Jenny, would you please come to my office? I need to talk to you.
　　J (Jenny): OK. What can I do for you?
　　M: Our factory is becoming better and better and now we need a new computer because our computer is too old. I want you and Mei Ge to buy a new computer for our factory.
　　J: Yes. What kind of computers you want us to buy?
　　M: I don’t know much about it. You and Mei Ge can ask for the price first.
　　J: OK. We will check the price first. But I think we should buy a PC 586, which is very new now.
　　M: Ask Mei Ge to check the price first. Tell me the decision next week.
　　J: All right. We will do that.
　　2. Make good preparation for the next lesson

教学设计方案Lesson 34

　　2. Write those purposes down on the blackboard “Games, Word Processing, Programming, Internet, Chat, Drawing, Watching Movies, Making Flash Movies…”
　　3. Ask Ss questions before they get to the text
　　1) What can computers do for CAAC?
　　2) How do the computers sell the tickets?

Step II Listening
　　Listen to the tape for Lesson 34 once

Step III Reading
　　1. Ask Ss to read the text
　　2. Answer the following questions without looking at the book
　　1)What is the computer used for in the CAAC?
　　2)What did people usually do when they wanted to buy a ticket before the use of computers?

　　3. Ask the next student to correct the mistakes if any

Step IV Discussion
　　1. Ask Ss to work in a group of four to discuss that whether 　computers are useful in our daily study of English
　　2. Ask each group to present their idea and opinions

Step V Language Points
　　1. Write down the useful expressions and ask Ss to explain and repeat the sentences teachers have given them
　　2. Ask Ss to make a short passage by using the words and expressions they have learned One possible answer:
　　In my opinion, studying abroad is very good for those students who want to improve their language, because if they make a decision to go abroad to study, their English will be greatly improved. They also can correct their pronouncing mistakes. At one time, there was no chance for Chinese people to go to other countries. But now we can be a passenger on the plane to other country. We believe it is necessary to change our life for a better one.
　　3. First, ask Ss to repeat the above passage
　　4. Ask them to make a new one by using at least 3 of the new words and expressions they have learned

Step VI Homework
