The children are being led into the garden.Teaching Time：Four periodsBackground InformationThe History of the puter The history of puters starts about 200 years agoBlaise Pascal was famous for building the first digital puter in 1642 Later Leibniz invented a special stepped gear mechanismThe prototypes made by Pascal and Leibniz were not used in many places，and considered strange unti1 a little more than a century later，when Thomas of Colmar created the first successful calculator that could add，subtract，multiply，and divide While he was developing the desktop calculator，some interesting developments in puters were started by Charles Babbage in Cambridge, England Between 1850 and 1900 great progress were made in mathematical physics，and it was known that most meaningful dynamic phenomena could be identified by differential equations so that easy means for their calculation would be helpful The invention of punched cards was a step to automated putingThat was used with puters by Herman Hollerith and James Powers in 1890They developed devices that could read the information stored in the cards by themselves panies saw these advantages and developed better punchcard，which used puters produced by International Business Machines(IBM), Remington(the same people that make shavers)，Burroughs，and other paniesThese puters used electromechanical devices in which electrical power changed into mechanical power. World Warproduced a large need for puter capacity，especially for the armyIn 1942，John PEckert，John WMauchly，decided to build a high-speed electronic puter to do the jobThis machine was known as ENIAC(Electrical Numerical Integrator And Calculator)It is monly considered the first high-speed electronic digital puter(EDC)and was used from 1946 to 1955 Von Neumann contributed a new idea of how practical，yet fast puters should be organized and builtThese ideas of stored program technique were essential and were widely usedThe first generation of electronic puters with these advantages were bu1t in 1947 Early in the 50s the discoveries of the magnetic core memory and the Transistor-Circuit Element changed the image of the electronicputer field，from fast but unreliable hardware to an image of relatively high reliab1ity and even more capability 1960s was turning pointIn this period，puter producers began to provide puters of different prices and capabilities，as well as accessories The trend during the 1970s was moving away from very powerfulsingle-purpose puters and toward a larger range of applications for cheaper puter systemsMost continuousprocess manufacturing now used puters of smaller capability for controlling and regulation their jobsIn the 1980s，very large scale integration(VLSI)became popularMany paniessuch as Apple puter and Radio Shackproduced very Successful personal puters(PCs)in the 1970s partly because of a fad in puter gamesIn the 1980s Apple and IBM kept strong in the crowded PC fieldIn the production of semiconductor chips，the Intel and Motorola corporations were very petitive, although Japanese panies were making great progress，especially in the area of memory chipsBy the late 1980s. at a time，could process about 4 000 OOO instructions per secondMicroprocessors equipped with read-only memory(ROM)now functioned a 10tinprocesscontrol，testing，monitoring，and diagnosing Cray Research and Control Data Incdominated the field of superputers，or the most powerful puter systems，through the 1970s and 1980sIn the early 1980s，however，the Japanese government announced a 1arge plan to develop a new generation of superputersThis new generation，the so called“fifth”generationEquipped with new technologies in large integration, they can amaze feats in the field of artificial intelligence, like voice recognitionProgress in software has not marched the great advances in hardwareSoftware is the main cost of many systems because programming productivity has not increased quicklyNew programming techniques，such as object-oriented programming，have been developed to solve this problemDespite difficulties with software，howeverthe cost per calculation of puters is rapidly decreasing, while their abilities will increase in the early futureThe puter field continues to experience huge growthputer networkingputer mail，and electronic publishing are just a few of the applications in recent yearsProgress in technologies continues to produce cheaper and more powerful putersIt shows that in the near future, puters or terminals will enter into mostIf not all homes，offices, and schoolsThe First PeriodTeaching Aims:1. Do some listening and train the students listening ability.2. Learn how to describe objects.3. Learn to make suggestions and give advice.Teaching Important Points:1. Improve the students listening ability.2. Master the expressions for making suggestions and giving advice.Teaching Difficult Points:1. How to describe objects correctly.2.

Can you give us some examples?S1:puters,cameras,mobile phones,(Teacher shows some pictures of them on the screen and writes the words on the blackboard.)T: Yes. Now please discuss in groups of four. Say something about them.(Teacher gives students five minutes to discuss and asks some students to talk about them before class. At the same time, he shows another few pictures on the screen.)S2puters are widely used in many fields. It is used not only in medicine, industry, agriculture, space research but also in our daily life and work. If the puter system isnt working, we cant go to the bank to make a deposit. We cant check some information, either. Now can we buy something in the supermarket or buy medicine in the chemists shop. We are now living in a puter world. Without puters, we are deaf, dumb and blind.S3: With the development of new technology, a new type of camera appears in the market and it is controlled by the puter. We cant imagine it if we dont see one. You dont need to put a roll in it and it can be used to take as many photos as you like. Everything can be controlled automatically. The pictures youve taken are very good and beautiful.S4: Mobile phones are changing fast. There are always new types in the market. A few years ago, we could only use them to municate with friends, relatives, etc. Now they can be used as cameras and radios, or to send e-mail as well as surf the Internet. Besides, the latest cell phones have some other new features. We can play games or listen to music on them. I think there will be more and more new types of mobile phones in the near future.S5:FStep .Warming upT: Well done. In the highly-developed world, you need to have good knowledge and imagination. You should also be a creative person and be good at solving problems and thinking in new ways. How creative are you? Now Ill give you some problems.

They are toothpicks socks and a plastic bag(Write them on the blackboard.)Do you know what they are usually used to do?S6:We usually use toothpicks to get bits of food out of the space between teeth.S7:We can wear socks to keep warm.S8:We often put things in plastic bags to carry them home or to a certain place.T: You are right. How many new uses can you think of for the things? Now use your heads and discuss them in groups of four. Try your best to think of as many new uses as you can.(Teacher gives students a few minutes to discuss them and asks some of them to give the answers.)S9: Toothpicks can be used when we eat something smaller. And they can also be used to pin something.S10:A sock can be used to clean things, hang things and fill something in. Besides, it can be used as a net fixed in the washing machine.S11:A plastic bag can be used to cover the seat of a bike when it is raining. And it can also be used as a glove when we pick up something oily or dirty. We can cover our hair with plastic bags when we are dyeing it.T: You are creative. I think they have more other new ways. Now look at the box on Page 57.Well do a word puzzle to see how many words you can make. You can move any side as many steps as you wish to make as many words as possible.(Teacher gives students a few minutes to prepare and then collects the answers from them.)S12:Stop,side,coat,door,poem,star,rate,Suggested words1. First row left to right: stop, side, soot, stem2. 2nd row left to right: coat, code, cram3. 3rd row left to right: aide, atom4. 4th row left to right: pram, poorT: Next lets do an even more interesting exercise. Read the sentences in the box on the right and tell us they are true or false. Who can tell me whether the first sentence is right or wrong?S13: Its true, I think.T: Yes. We can get the word “boat” from the word “automobile”(Write it on the Bb.)What about the second sentence?S14: Its wrong.12 minutes past 5 oclock is 48 minutes before 6 oclock.T: Right. The third sentence, if you have a try, its clear.(Show a left-handed glove to the students.)Wholl e here to have a try before the whole class?(A student has a try before the class.)Ss: The third sentence is true.FStep .ListeningT: Now lets do some listening. First you should read the listening requirements on Page 58.(Teacher gives students some time to read it and then plays the tape for them.)T: Now lets listen to the tape for the first time to get the general idea.(Teacher plays the tape twice. He may pause for the students to write down some information and repeat some parts of the tape if necessary. Finally teacher checks the answers with the whole class.)Suggested answers to Ex.1Object describedPossible uses1.ChopsticksEating, opening a bottle,2.CellphoneMaking, phone calls, sending pictures, sending e-mails3. RefrigeratorKeeping food fresh, keeping drinks coolT: Lets e to Ex.2. From the listening material, we know how to describe things. Now lets practice doing it and well have a petition. One student thinks of a certain object used in our everyday life and describes it. The partner tries to guess what it is. Now Ill give you four minutes to prepare this in pairs.(After a few minutes, teacher asks some pairs to act out before class to see which pair does best.)Some examples:1. A:a group of strong hairs at the end of a handle that can be used for cleaning.B: brush2. A:a large metal or plastic container that people keep outside their houses and in which they put things they want to get rid ofB: dustbin3. A:a small piece of special paper that you stick on letters to show how much you have paid to send themB: stampStep V SpeakingT: Well done. In our daily life what should we do when we get into trouble or when we want to buy something expensive and cant make a decision?S: We should ask our friends or parents for some advice.T: Yes. When someone asks for some advice, how can you give any advice to him in English? Weve learnt some expressions for making suggestions. Whod like to tell them to me?(Teacher collects the expressions from some students and writes them on the blackboard.)T: Now Jane wants to buy a cell phone. Before she can buy one, she wants her parents and best friend to give her some advice. Her father agrees with her, but her mother and her best friend dont agree. With her, but mother and her best friend dont agree. Now please form a group of four to have a discussion about whether middle school students need a cellphone.(A few minutes later, teacher collects the students answers.)Possible answers:Jane1. I can use a cellphone to call my parents if I am late.2. I can use a cellphone to call for help.3. I can use a cellphone to stay in touch with my friends.Janes best friend1. We dont really need cellphones.2. We are not allowed to use celphones in school.3. It is better to use the money for something more important.1. Cellphobes are too expensive.2. Jane should not spend too much time Janes mother.on the phone3. Jane is too young to have a cellphone.Janes father1. If Jane has a cellphone, I can always find out where she is.2.

Mum, Dad, you know I have told you before that I want to buy a cellphone. I would like to tell you why I want to buy one, and I would like your adive.Dad: OK, why dont you start and then we will all tell you what we think.Jane: Thanks, Dad. I think a cellphone is very useful, because I can use it to let you know where I am and when I will be back home. For example, if I have to stay late at school, you might get worried and wonder where I am . If I have a cellphone, I where I am. If I have a cellphone, I can call you and tell you that I will be late.Mum: Well, thats true, but I dont think you should buy a cellphone. In my opinion, a cellphone is too expensive. Besides, if you have a cellphone I think you will spend too much time talking on the phone. Youd better use your time to study instead.Cindy: I agree with Mrs Collins. Some of the other students in our class have cellphones and they talk on the phone all the time, I dont see how they ever have time for anything else. And it is expensive. One of my classmates said that she spent 110 yuan in one month!Dad: Jane, I think you are right. I often worry about where you are and I never know when I will be home from work. I remember last year, when you were at the supermarket and I had promised to pick you up. I was late and couldnt find you when I got there. If you have a cellphone I can just call you.Jane: Thank you for telling me what you think. I will take some time to think about what you have said. Now lets have some fun. How about playing some cards!Jane: Thank you for telling me what you think. I will take some time to think about what you have said. Now lets have some fun. How about playing some cards!Step . Summary and HomeworkT: Today weve done some listening and learnt how to describe things. We have also practised describing objects and giving somebody some advice.
