students name them in English.Through this task，st udents can have a general idea about what they are going to learn.Besides，students are expected to have a discussion about what they have in common 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 too expensive.T：Quite good.It seems that you are all quite familiar with these machines.But can you tell what they have in common?Any volunteers?S6：Let me try.I think they all calculate something.They can deal with some maths problems.S7：I believe that they are our good friends.With their help we can finish our work quickly.S8：The 21th century is the century of information technology.As middle school students，we should try to learn how to use computers.T：Well，your opinions are all right.Indeed，these machines all can calculate something.What’s more，from the abacus to the notebook computer，there is a long way.But now computers have already changed our lives greatly.But do you know more about computers and can you say something about how com puters have changed our lives.Step 2 Pre-readingShow the questions on the screen.T：Now，please have a discussion first，and then I’ll ask some students to report your work.After a few minutes.T：Now，who would like to answer the first question?V oluntee r!S9：I’ll have a try.I know that computers have developed from large machines.They have been made smaller and smaller，but work faster and faster.I really can’t imagine what they will be like and wh ether they can take the place of human beings in the future.T：Yes，this is really a big problem.I think you are all interested in computers，you may go on studying computers，and 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 of controlling the world.We may communicate with each other from a very long distance.In short，we can not live freely without them.T：I agree with you.The computers are becoming more and more important in our lives.But learning more about computers is also importa nt，isn’t it?OK，let’s come to the reading passage “Who am I”.Step 3 ReadingTask 1.Skim the passage for the general idea.T：Boys and girls，you will be given two minutes to skim the passage and try to find out who “I” am and get the general idea of this pa ssage.After two minutes.T：Time is up.Who would like to tell us who “I” am and give the general idea of the text to the class?V

was in France as a calculating machine in 1642.In 1822，I was built as an Analytical Machine by Charles Babbage.I was called “a universal machine”in 1936，as I could solve any mathematical problem.In 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 quick-minded that in such a short time you could find out all the answers to the questions.Your mind really works like a computer!Step 4 ComprehendingTask 3.Fill in the timeline to remember the facts.T：But can you memorize facts like a computer?I am afraid you can not.But let’s try to remember the facts in the passage by filing in the timeline on Page 19，which，I am sure，will help you

development of computers.Now who would like to retell the text with the help of these figures?S1：Let me try.In 1642，a calculating machine was used in France.Then in 1922，the Analytical Machine was made by Charles Babbage.It could follow instructions from cards 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

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
