Through this task，students 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：Boys and girls，today I am going to introduce some machines toyou. 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 often 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.

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.

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，wrote a book to describe how computers could be made to work and built a “universal machine” to solve any mathematical problem. Later，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 readingpassage，find the words and expressions with the following meanings. Now， ten students will be asked to give the words. Who can? Volunteers!Check the answers together.Task 2.T：Well done. Now please look at Ex 2.and complete the passage with some of the words above. Pay attention to the use and the forms of those words.The possible answers：network so that went by totally truly simple-minded Anyway deal withTask 3T：Please finish Ex.3.Look at the sentences on Page 20.Tick the right word.Then some of you will be asked to read the sentences one by one.The possible answers：1.Life totally changed when I went to university.2.I was amazed to find that I won the competition to design a new computer.3.The competition was so exciting that we cheered all evening.4.I was so excited at the thought of meeting Yang Liwei thatI could not sleep.5.Robots can be bought so cheaply that I gave one to each of my friends.6.It was so unlucky that you lost your watch at the concert.

Think of thefun you could 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 th en 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.

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.

For example, puters have bee our good friends: with the help of puters, people all over the world are able to share whatever information on the net, which shortens the distance between them. With the invention of radio and TV, people now can stay at home to get themselves informed about both domestic and international news.But as a coin has two sides, technology can also have an negative influence upon people’s life. Now technology crimes are very mon. What’s more, the nuclear bomb threatens our human existence. So I think we must pay enough attention to the misuse of technology.In spite of its disadvantages, we should admit that technology is very useful. Without science and technology, man’s life would not be as convenient as today.Ⅱ. 按要求完成任务1. 写出文章中表示“任何事情都有两面性”的句子。
