while looking at them.And they are required to use the given expressions in their discussion to express their ideas.T：B oys and girls，today I am going to introduce some machines to you.Now let’s see whether you can name them in English correctly，and talk about them.Now work together with your partners and try to find out what they have in common.Two minutes late，five students are asked to talk about them in class.S1：An abacus is an old calculating machine used in China until now.S2：A huge computer is built to solve some mathematical pro blems.But，in my opinion，it is too big.S3：A calculator is a new calculating machine which can solve a large number mathematical problems.And I think it is very convenient to carry and use，so we ofte n use it.S4：A PC is a personal computer，which can solve all kinds of problems and is widely used in offices，schools，shops，at homes，etc.now.S5：A notebook computer is a kind of useful computer which can be taken conveniently like a notebook.But I think it is

perhaps one day you will design your own computers and become the masters of computers.OK!Next question!S10：I think computers have changed our lives greatly.We use computers widely in our study，in our work.You are using the computer to teach us English，aren’t you?S11：In my opinion，in the modern society，using the computers means grasping a tool ofcontrolling the world.We may communicate with each

the 1960s，I was given a family connected by a network，so that I could share information with others and we could talk to each other.In the 1970s，I was brought into people’s homes.T：You are so

with holes.In 1936，Alan Turing，the real father of computers，wro te a book to describe how computers could be made to work and built a “universal machine”to solve any mathematical ter，people discovered the computer had “artificial intelligence”.In the 1960s，the computer got his new transistors.Its size was totally changes at that time.And in the early 1960s，the first family of computers were connected to each other.In 1970s，computers have brought into people’s homes.Now computers have been used by billions of people to deal with information and communicate with each other around the world by the Internet.T：Congratulations!You’ve done very well.Now try to do the same to your partners，OK!Step 2 Words and ExpressionsTask 1T：Please turn to Page 19 and finish Discovering Useful Words and Expressions.At first，look at Ex.1.From the reading passage，find the words and expressions with the following meanings.Now，ten students will be asked to give the words.Who can?V olunteers!Check the

TeachingPeriod 3 Extensive ReadingThe General Idea of This Period：This perio d includes revision of the text，Reading and speaking on Page 22、Reading task on Page 58.In this period the students will be involved in a speaking activity about designing anandroid after reading the story of Andy，an d learn something about the performances of a sporting robot of the 22nd century，Hua Fei in 78th Olympics and 79th Olympics，so that the students will not only improve their reading and speaking，but also their creative thinking.Teaching Aims：1.Help the students to learn about the different ways of designing the robots and give their opinions to the class.2.Enable the students to discuss to design their own robots.Talk about the different ways of designing the robots.Teaching Important and Difficult Points：How to design their own robots and report their designing to the class.Teaching Methods：1.Task-based learning.2.Cooperative learning.Teaching Aids：1.A tape recorder.2.A multimedia.Teaching Procedures：Step 1 GreetingsStep 2 Reading （1）We’ve learned a lot about computers，but can you imagine that computers could be put into androids or robots.Think of the fun you c ould have!Now let’s first read the passage about a robot called Andy—what it looks like and what it can do on Page 22，and then we’ll have a des igning competition to see who will design the best robots.The students read the passage fo r several minutes.T：A few simple questions for you.What does Andy look like?What can it do?S2：Andy looks like a human.It is designed to play football games and can move and think like a human.Andy is really smart.T：I agree with you.Are you eager to design your smart robots?Now in small groups discuss how to design your own androids，draw a picture of your androids and write down your design.You may refer to the following questions：1.What would you like it to look like?2.What are some of the things you would like it to do?3.Do you want it to be like a man or a woman or neither?4.How much would it cost?T：And don’t forget to use the following expressions in your discussion.I think thatIn my opinion...What is your reason?I have decided that...After several minutes.T：Now，I’ll check your work.One from each group will show your picture of the android you have designed and tell the class your design.And we’ll see which group has designed the best android.Who would like to try first?S3：Look here.This is the picture of the robot we’ve designed.What does it look like?Yes，it looks like a dog.We all like dogs very much.Every morning it will wake us up so that we will not be late for school.Then it will company us to school and carry our heavy bags.You know how heavy our bags are!In the evening，after a whole day’s hard work，it will play beautiful music to help us relax.Maybe it will cost at least 2000 yuan，but we don’t think it is too expensive to have such a good friend.S4：Well，we’d like to design our robot in this way.We would like it to look like the famous footballer Beckham who serves as a striker on the football team.It has the most advanced program，so it can move and think like Beckham，and of course can shoot good goals like him.We would like it to enter the next Electronic World Cup，and we are sure that it will win the cup!T：Your designs are very unusual and smart.I really want to go on appreciating your designs，but time is limited.Will you put up your pic tures of the robots you have designed with instructions on the back wall，and then decide which group has designed the best androids after comparison?Step 3 Reading （2）Class，let’s come to the Reading Task on Page 58.First read the passage quickly and then fill in the chart of Exercise 1 and keep a record of his performances of the sporting robot of the 22nd
