I began as a calculating machine in France in 1642. Although I was young I could simplify difficult sums. I developed very slowly and it took nearlytwo hundred years before I was built as an analytical machine by Charles Babbage. After I was programmed by an operator who used cards with holes, I could "think" logically and produce an answer quicker than any person. At that time it was considered a technological revolution and the start of my "artificial intelligence". In 1936 my real father, Alan Turing, wrote a book about how I could be made to work as a "universal machine" to solve any difficult mathematical problem. From then on, I grew rapidly both in size and in brainpower. By the 1940s I had grown as large as a room, and I wondered if I would grow any larger. However, this reality also worried my designers. As time went by, I was made smaller. First as a PC (personal computer) and then as a laptop, I have been used in offices and homes since the 1970s.These changes only became possible as my memory improved. First it was stored in tubes, then on transistors and later on very small chips. As a result I totally changed my shape. As I have grown older I have also grown smaller. Over time my memory has developed so much that, like an elephant, I never forget anything I have been told! And my memory became so large that even I couldn't believe it! But I was always so lonely standing there by myself, until in the early 1960s they gave me a family connected by a network. I was able to share my knowledge with others through the World Wide Web.Since the 1970s many new applications have been found for me. I have become very important in communication, finance and trade. I have also been put into robots and used to make mobile phones as well as help with medical operations. I have even been put into space rockets and sent to explore the Moon and Mars. Anyhow, my goal is to provide humans with a life of high quality. I am now truly filled with happiness that I am a devoted friend and helper of the human race!一级阅读目标:Ⅰ.

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 mathsproblems.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

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

have.I 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

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 discoveredthe 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?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：ne twork so that went by totally truly simple-minded Anyway deal with Task 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 that I could not sleep.5.Robots can be bought so cheaply that Igave one to each of my friends.6.It was so unlucky that you lost your watch at the concert.Task 4T：Please turn to Page 56 and let’s finish Using Words and Expressions.First look at Ex.1.Read through the words in the right-hand box e some of them to name each part of a computer in the left-hand box.We have known about computer.But who can give us the exact names?The possible answers：1.floppy disc2.hard disc3.scanner4.modem5.CD-ROM6.monitor7.keyboard8.printerTask 5T：Now please look at plete the sentences with some of the words in the right-hand box above.You can use each word only once.First do the exercise individually，and then check yo ur answers with your partners.And last seven students will be asked toreport their answers to the class.The possible answers：1.A printer is a machine for printing text or pictures onto paper，especially once connected toa computer.2.A CD-ROM or disk is the main device that a computer uses to store information.3.A monitor is used to see your data on a computer.4.A keyboard is used to put data into a computer.5.A CPU is often used to conne ct computers to each other through phone lines.6.Data can also be stored in a floppy disc，which is small and can be carried easily.7.A hard disc is a disc that contains computer data.It can store a large amount of data.Step 3 Grammar—The Present PerfectPassive VoiceT：Boys and girls，now please pay attention to the following sentences in the text：1.As the years have gone by，I have been made smaller and smaller.2.Since then，my family and I have been used by billions of people to deal with information and communicate with each other around the world by the Internet.3.I have truly been built to serve the human race since my birth.T：What verb tense is used in these sentences?And what verb voice is used in these sentences?Yes，the present perfect pa ssive voice is used in these sentences.Can you tell us the structure of the present perfect passive voice?Quite right.The structure of the present perfect passive voice is “subject＋have/has been done＋object”.The function of present perfect passive voice is indicating verbs’the present perfect and the passive voice.OK，let’s practise the
