M2 Unit 3 ComputerPeriod 1:Warming up(WHO AM I?)Warming upThis section is an introduction to the topic．It is to get the students thinking about the different ways computers can be made．Do this part of the lesson in pairs and as a speaking activity．Warming up by talking about computerLook at the pictures on page 17. What are they? What do they have in common? Yes, they are computers. Then what is a computer?A computer is a machine which stores knowledge in its memory and does calculations on that knowledge. This knowledge is stored in symbols; it is called data. A computer usually has a monitor to show results. However, some computers can speak; these computers can be used for voice mail.Draw on the blackboard a diagram to illustrate the influence of the computer and the Internet over the school education．Below is a diagram you may like to use．Ask students to look at the diagram and consider, ”What changes have computers and the Internet brought to schools? What changes will they bring to schools in the future?”Ask the Ss to work in groups and to make a list of the possible changes they can think of．When most of the groups have their lists ready, the teacher can hold a class discussion．Write down the major changes the students think of under / beside the diagram．The teacher can add one or two changes that may affect their own teaching．For example, “Computers and the Internet can help busy parents contact teachers by email．”The teacher can end the task with a brief summary, or hold a further discussion to find out students' personal opinions about the changes．For example, ask them, “Do you like all these changes? Why and why not? What changes do you like / dislike?”Some information:计算机室A computer frequently requires a boot device. The boot device contains the computer’s operating system and data. Computer programs can be installed onto a computer. Some people think that computers are less useful if they do not have access to the Internet. They think this because the Internet allows the computers to send and receive data and email across the world.曙光3000巨型计算机A computer is now almost always an electronic device. It usually contains materials which are toxic; these materials will become toxic waste when disposed of. When a new computer is purchased in some places, laws require that the cost of its waste management must also be paid for. This is called product stewardship.In some countries old computers are recycled (melted down) to get gold and other metals. This is dangerous, because this procedure releases the toxic waste into the water and soil.Computers become obsolete quickly. Very often they are given away and new ones replace them within two or three years. This makes the problem worse. Computer recycling is thus common. Many projects try to send working computers to developing nations so they can be re-used and will not become waste as quickly. Computer jargon 计算机行话Computer jargon means words to do with computers and surrounding topics. Knowing what these words mean can help you know more about computers. Some people use these words to impress other people (Also known as buzzwords). Examples of jargon:Bit - The smallest data unit, can either be a “0.” or a “1.”.Byte - unit of data. See also Kilobyte, Megabyte, Gigabyte and NibbleCPU –Central Processing Unit, Another name for processorData - Information stored on a computerDisk - A place to store data.Email - Electronic mail.GHz - Gigahertz. Used often incorrectly to describe the speed of a processor. But with some 2.4 GHz processors faster than 3.6 GHz ones, it is clear that it is just a salesman trick.Load - Get data from a diskNibble - Half a ByteSave - Put data on a diskRAM – random-access memory(随机存取存储器), the more the better.USB - Universal Serial Bus（通用串行总线，一种简化了插接多种附件的薄型插座）WWW - World Wide Web, part of the InternetPeriod2-3 Pre-reading & ReadingPre-readingThis can be a continuation of the Warming Up．Let the students discuss the questions set out in the Student's Book．1. Questioning and answering What do you know about computer?●Electronic machine capable of performing calculations and other manipulations of various types of data, under the control of a stored set of instructions. The machine itself is the hardware; the instructions are the program or software. Depending upon size, computers are called mainframes, minicomputers, and microcomputers. Microcomputers include desk-top and portable personal computers.●A multi-function electronic device that can execute instructions to perform a task.●A device that accepts information, processes it, and supplies an output. A computer usually contains memory, a control unit, arithmetic and logical units, and a means for input and output.●a programmable hardware component that is controlle d by internally stored programs and that can perform substantial computations (including arithmetic andlogic operations) without human intervention. A computer typically consists of one or more processing units, memory units, and associated peripheral input and output devices.●Related to automation and electronic data processing. The Library of Congress commonly classes most computer-related books in HF5548, QA75-76, Z52, T385, and some TK ranges.●a machine for performing calculations automaticallycalculator: an expert at calculation (or at operating calculating machines)●A computer is a device or machine for making calculations or controlling operations that are expressible in numerical or logical terms. Computers are constructed from components that perform simple well-defined functions. The complex interactions of these components endow computers with the ability to process information. If correctly configured (usually by, programming) a computer can be made to represent some aspect of a problem or part of a system. If a computer configured in this way is give2. Discussing and sharing How have computers changed our lives?Someday soon, if you haven’t already, you’re likely to plug into the computer network nation growing in our midst. Computer terminals, or small computers connected via modem (a modulator/demodulator circuit for encoding/decoding computer chatter) to ordinary telephone lines, should be as ubiquitous as the telephone itself. They’re a much more useful and humane tool than the phon e, and with corporate America behind them the networks will be everywhere----changing our lives more than any technology since the automobile.Joining a computer network is the same as joining a community. Small systems are like villages, where new members are formally welcomed. The larger networks, the Source and CompuServe, for example, are cities-anonymous, full of life and events, but difficult to fit into.II. ReadingThis is the purpose of the reading and so it is important that the students learn to use all the clues in the text to help them understand the gist of what they are reading．So encourage them to look at the pictures and the heading and guess what the text might be about．Then ask the class to read the passage silently．Make sure the students have the chronology of the development of computers in their minds．Ask them:1. Listening and reading to the recording of the text WHO AM I?Turn to page 18 and listen and read to the recording of the text. Pay attention to the pauses, pronunciation and intonation of the native reader.2. Reading aloud and underlining expressionsNow we are to read the text once again and underline all the expressions in the text. Put them down into your notebook after class as homework.Collocations from WHO AM I?begin as…, a calculating machine, be built as…, follow instructions from…, sound simple, at the time, a technological revolution, write a book, make…work, solve problems, become huge, had artificial intelligence, go back to…, the size of…, go by,change size, become small and thin, get quick, stand there by oneself, be connected by…, share information by…, talk to…, bring…into…, deal with…, communicate with…, serve the human race3. Reading, identifying and settlingAttention, please! It is time to skim the text one more time and identify the difficult sentences. Try analyzing the structures of the difficult sentences and discuss them among your group members. You may also put your questions to me for help.Chat （online）（在线）聊天To chat is to talk about ordinary things that are not very important. You can chat to one person or to many people. People also use this word now for parts of the Internet where we can talk with many different people at the same time. Usually, you chat on the internet in a chat room or messaging service like AOL(American On-Line) Instant Messenger (AIM), Yahoo Messenger, or MSN Messenger.IV. Closing down by doing comprehending exercisesTurn to page 18 and in pairs do the comprehending exercises No. 1 and 2.

students name them in English.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 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 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 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 computers 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 olunteer!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 whether 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 ofcontrolling 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 important，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 passage.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

the details.T：Boys and girls，you will be given two more minutes to scan the passage and try to find out the answers to the following questions.Let’s see who can find out the answers most quickly and correctly.1.Where were you in 1642?2.What happened to you in 1822?3.What were you called in 1936?4.What did you get in the 1960s?5.What happened to you in the 1970s?T：Have you finished?S14：I 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 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 remember the facts easily.Suggested answers：Timeline1642：The computer began as a calculating machine.1822：The Analytical Machine was built by Charles Babbage.1936：Alan Turing wrote a book to describe how computers could be made.1960s：Computers had new transistors and became smaller.1960s：The first family of computers connected to each other.1970s：Computers were brought into people’s homes.Now：Computers connect people all over the world together.T：Have you finished?If so，please check your answers yourself.I’m sure all of you have got them right.Now you can retell the history of

Unit 3 Computers 教案2(WHO AM I? <PART 2>)IntroductionYou are advised to lead in by talking about IT. Then help students write a report about IT.ObjectivesTo discuss about ITTo write a report about ITTo read about androids or robotsProceduresI. Warming up by talking about ITWhat is Information technology?Information technology (IT) or information and communication technology (ICT) is the technology required for information processing. In particular the use of electronic computers and computer software to convert, store, protect, process, transmit, and retrieve information from anywhere, anytime.II. Listening and writingTurn to page 21.Look at the pictures and listen to a conversation about different kinds of information technology or IT, discuss and write down in groups the advantages and disadvantages of each kind.III. Speaking and writingSuppose you and your partner are going to help choose computers for your school. Now talk about the special things each of the computer can do and write a report to your headmaster.IV. Reading, underlining and speakingIt is said that computers could be put into androids or robots. Read the text Andy—The Android, underlining all the expressions and think of the fun you could have!Expressions from Andy—The Androidp art of a football team, once a year, get together, play a football game, be as…as…, in fat, look like…, on the football team, run fast, think like a human, shout to…, in computer language, have a good shot for a goal, get second place, win the first place, have a new kind of program, improve one‟s intelligence, create a better system, play against a human team, in a way, program…with…, make up…, after all, with the help of…V. Close down by writing a letterSuppose you are an android. What would say to a spoiled child who would not do his homework? Write a letter to the boy.AndroidAn android is an artificially created being that resembles a human being.The word derives from Greek Android- …man, human‟ and the suffix -eidesused to mean …of the species, kind, alike‟ (from eidos …species‟).The word droid, a robot in the Star Wars universe, is derived from this meaning. Some people maintain that, etymologically, the word android means resembling a male human and that a robot resembling a woman should logically be called a gynoid for sexist language to be avoided; however, this word is not commonly used.Unlike the terms robot (a mechanical being) and cyborg (a being that is partly organic and partly mechanical), the word android has been used in literature and other media to denote several different kinds of man-made, autonomous creations:a robot that closely resembles a humana cyborg that closely resembles a humanan artificially created, yet primarily organic, being that closely resembles a humanAlthough essentially human morphology is not the ideal form for working robots, the fascination in developing robots that can mimic it can be found historically in the assimilation of two concepts: simulacra (devices that exhibit likeness) and automata (devices that have independence).The term android was first used by the French author Mathias Villiers de lisle-Adam (1838-1889) in his work Tomorrow’s Eve, featuring a man-made human-like robot named Hadaly. As said by the officer in the story, “In this age of Realien advancement, who knows what goes on in the mind of those responsible for these mechanical dolls.”。
