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

Unit 3 Computers 教案1（WHO AM I?<PART 1>)IntroductionIn this period, after the warming up, students will first be guided to imagine and share their views about the technology. They will then be helped to read a narration entitled WHO AM I.Examples of “Warming Up” designs are presented in this book for teachers’ reference. Computer and overhead projector may be used to aid the teaching and learning. ObjectivesTo talk about computerTo read about computerFocusWords simplify, sum, operator, logically, solve, reality, personal, network, finance, applications, exploreExpressions technological revolution, artificial intelligence, as a result, anyhowPatterns From then on, I grew rapidly both in size and in brainpower.As a result I totally changed my shape.Over time my memory has developed so much that, like an elephant,I never forget anything I have been told!AidsMultimedia facilities, tape-recorder, photos, diagramsProceduresI. Warming up1. 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.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 whichare 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.II. Pre-reading1. Questioning and answering---What do you know about computer?(1) 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.(2) A multi-function electronic device that can execute instructions to perform a task.(3) A device that accepts information, processes it, and supplies an output. A computerusually contains memory, a control unit, arithmetic and logical units, and a means for input and output.(4) A programmable hardware component that is controlled by internally stored programs and that can perform substantial computations (including arithmetic and logic operations) without human intervention. A computer typically consists of one or more processing units, memory units, and associated peripheral input and output devices.(5) Related to automation and electronic data processing.

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 phone, 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.

Happiness is for everyone. You don't need to care about those people who have beautiful houses with large gardens and swimming pools or those who have nice cars and a lot of money and so on. Why? Because those who have big houses may often feel lonely and those who have cars may want to walk on the country roads at their free time.In fact, happiness is always around you if you put your heart into it. When you are in trouble at school, your friends will help you; when you study hard at your lessons，your parents are always taking good care of your life and your health; when you get success，your friends will say congratulations to you; when you do something wrong，people around you will help you to correct it. And when you do something good to others，you will feel happy，too. All these are your happiness. If you notice them，you can see that happiness is always around you.Happiness is not the same as money. It is a feeling of your heart. When you are poor，you can also say you are very happy，because you have something else that can't be bought with money. When you meet with difficulties，you can say loudly you are very happy，because you have more chances to challenge yourself. So you cannot always say you are poor and you have bad luck.As the saying goes，life is like a revolving door. When it closes，it also opens. If you take every chance you get，you can be a happy and lucky person, and you will have happiness forever.Ⅳ.完形填空My daughter has been saving her birthday money for almost nine months now.She did it so that she could __1__ an iPod touch with a camera in it.Up to this morning, she had saved the __2__ amount needed and headed to the Apple Store in Utah with my wife.They arrived at 10：30 am, not __3__ that the store would be closed from 11 am to 2 pm today.As they __4__ the store, two friendly Apple __5__ greeted them and said that they were sorry, but their store would be closed.My wife __6__ my daughter who had a jar full of cash in her arms and __7__ why they were there.They __8__ said they were sorry, but could not let them in.My wife and daughter were __9__，but understood and made their way to another store in the mall.About three stores down, one of the two men __10__ them and said that the manager was going to make a(n) __11__ and let them in.When they were let in the store, they were the __12__ customers in the place and everyone __13__ what they were doing to serve them.__14__ she took all of the cash out of the jar, a crew member stepped __15__ to help her and said, “I have to tell you that this made my day.”After __16__ the iPod, my daughter and wife were on their way out; the store manager __17__ his voice and said to his crew members, “Everyone, please use your __18__ to give the girl a round of applause for saving her money and buying an iPod today.”My daughter was caught a little off guard by all of the__19__ and waved goodbye, and then left.The Apple Store earned a __20__ forever by doing this.1．A.borrow B．afford C．find D．see2．A.total B．large C．certain D．growing3．A.guessing B．doubting C．hoping D．knowing4．A.approached B．entered C．left D．called5．A.customers B．employees C．fans D．users6．A.looked after B．dealt with C．pointed to D．picked up7．A.asked B．recorded C．wondered D．explained8．A.again B．almost C．ever D．also9．A.calm B．helpful C．sad D．forgetful10．A.thought of B．ran after C．talked about D．waited for11．A.difference B．sense C．exception D．mistake12．A.familiar B．only C．usual D．first13．A.showed B．imagined C．completed D．stopped14．A.As B．Unless C．Until D．Though15．A.downward B．backward C．outward D．forward16．A.throwing away B．putting aside C．paying for D．turning off17．A.raised B．lowered C．found D．tried18．A.feet B．hands C．legs D．eyes19．A.ideas B．listening C．occasions D．attention20．A.place B．customer C．fortune D．living参考答案GrammarⅠ.1.has been connected 2.has been stopped 3.has been changed 4.have been taught 5.have met 6.has been finished7.lent8.were expected9．have been promised10.have been discoveredⅡ.1.have been built 2.has been broadcast 3.have been produced4．has been made 5.hasn't been decidedⅢ.One possible version：Happiness is for everyone and you don't need to care about other people.(要点1) Happiness is always around you if you put your heart into it.
