them.And they are required to use the given expressions in their discussion to express their ideas.T：Boys 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 mon.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 puter is built to solve some mathematical problems.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 often use it.S4：A PC is a personal puter，which can solve all kinds of problems and is widely used in offices，schools，shops，at homes，etc.now.S5：A notebook puter is a kind of useful puter which can be taken conveniently like a notebook.But I think it is too

are all interested in puters，you may go on studying puters，and perhaps one day you will design your own puters and bee the masters of puters.OK!Next question!S10：I think puters have changed our lives greatly.We use puters widely in our study，in our work.You are using the puter to teach us English，aren’t you?S11：In my opinion，in the modern society，using the puters means grasping a tool of controlling the world.We may municate with each other from a very long distance.In short，we can not live freely without them.T：I agree with you.The puters are being more and more important in our

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 puter!Step 4 prehendingTask 3.Fill in the timeline to remember the facts.T：But can you memorize facts like a puter?I am afraid you can not.But let’s try to rememberthe facts in the passage by filing in the timeline on Page 19，which，I am sure，will help you remember the facts easily.Suggested answers：Timeline1642：The puter began as a calculating machine.1822：The Analytical Machine was built by Charles Babbage.1936：Alan Turing wrote a book to describe how puters could be made.1960s：puters had new transistors and became smaller.1960s：The first family of puters connected to each other.1970s：puters were brought into people’s homes.Now：puters connect people all over the world together.’m sure all of you have got them right.Now you can retell the history of puters easily with
