The Present Continuous Passive Voice is used to describe something that is being affected or dealt with. e.g. New functions are being added to the phones. Michel is being interviewed for the job. Modern cellphones are being used as cameras and radios. 2. The Present Continuous Passive Voice is used to describe somebody who is accepting an action or is being dealt with passively. e.g. The new student is being introduced to the class. Look! The children are being led into the garden. Ⅲ．Teaching Time：Four periods Ⅳ．Background Information The History of the puter The history of puters starts about 200 years ago．Blaise Pascal was famous for building the first digital puter in 1642． Later Leibniz invented a special stepped gear mechanism．The 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 puting．That was used with puters by Herman Hollerith and James Powers in 1890．They 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 panies．These puters used electromechanical devices in which electrical power changed into mechanical power. World WarⅡproduced a large need for puter capacity，especially for the army．In 1942，John P．Eckert，John W．Mauchly，decided to build a high-speed electronic puter to do the job．This 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 built．These ideas of stored program technique were essential and were widely used．The first generation of electronic puters with these advantages were bu1t in 1947． Early in the 50’s the discoveries of the magnetic core memory and the Transistor-Circuit Element changed the image of the electronic—puter field，from fast but unreliable hardware to an image of relatively high reliab1ity and even more capability． 1960’s was turning point．In this period，puter producers began to provide puters of different prices and capabilities，as well as accessories． The trend during the 1970’s was moving away from very powerful．single-purpose puters and toward a larger range of applications for cheaper puter systems．Most continuous—process manufacturing now used puters of smaller capability for controlling and regulation their jobs． In the 1980’s，very large scale integration(VLSI)became popular．Many panies．such as Apple puter and Radio Shack．produced very Successful personal puters(PCs)in the 1970s partly because of a fad in puter games．In the 1980s Apple and IBM kept strong in the crowded PC field．In 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 chips．By the late 1980s. at a time，could process about 4 000 OOO instructions per second． Microprocessors equipped with read-only memory(ROM)now functioned a 10tinprocess—control，testing，monitoring，and diagnosing． Cray Research and Control Data Inc．dominated the field of superputers，or the most powerful puter systems，through the 1970s and 1980s．In the early 1980s，however，the Japanese government announced a 1arge plan to develop a new generation of superputers．This new generation，the so called“fifth”generation．Equipped with new technologies in large integration, they can amaze feats in the field of artificial intelligence, like voice recognition． Progress in software has not marched the great advances in hardware．Software is the main cost of many systems because programming productivity has not increased quickly．New programming techniques，such as object-oriented programming，have been developed to solve this problem．Despite difficulties with software，however．the cost per calculation of puters is rapidly decreasing, while their abilities will increase in the early future． The puter field continues to experience huge growth．puter networking．puter mail，and electronic publishing are just a few of the applications in recent years．Progress in technologies continues to produce cheaper and more powerful puters．It shows that in the near future, puters or terminals will enter into most．If not all homes，offices, and schools． The First Period Teaching 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. How to give somebody some advice. Teaching Methods: 1. Free-talk method to get the students to know something about science and technology. 2. Warming-up to arouse the students’ imagination. 3. Listening activity to have the students go through the listening material. 4. Speaking activity to make the students finish the speaking task and improve the students’ speaking ability. Teaching Aids: 1. a puter 2. a tape recorder 3. some cards and some objects Teaching Procedures: FStep Ⅰ.Greetings Greet the whole class as usual. FStep Ⅱ.Free Talk T: As we know, science and technology are developing very fast, especially in the last ten years. 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 isn’t working, we can’t go to the bank to make a deposit. We can’t check some information, either. Now can we buy something in the supermarket or buy medicine in the chemist’s 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 can’t imagine it if we don’t see one. You don’t 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 you’ve 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 Ⅲ.Warming up T: 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 I’ll give you some problems. You should try to solve them in new ways. (Teacher shows toothpicks, a pair of socks and a plastic bag to the students.) Now look at the objects in my hands. We are familiar with them. 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.We’ll 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 words 1. First row left to right: stop, side, soot, stem 2. 2nd row left to right: coat, code, cram 3. 3rd row left to right: aide, atom 4. 4th row left to right: pram, poor T: Next let’s 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: It’s 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: It’s wrong.12 minutes past 5 o’clock is 48 minutes before 6 o’clock. T: Right. The third sentence, if you have a try, it’s clear.(Show a left-handed glove to the students.)Who’ll 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 Ⅳ.Listening T: Now let’s 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 let’s 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.1 Object described Possible uses 1.Chopsticks Eating, opening a bottle,… 2.Cellphone Making, phone calls, sending pictures, sending e-mails… 3. Refrigerator Keeping food fresh, keeping drinks cool… T: Let’s e to Ex.2. From the listening material, we know how to describe things. Now let’s practice doing it and we’ll 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 I’ll 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: brush 2. A:a large metal or plastic container that people keep outside their houses and in which they put things they want to get rid of B: dustbin 3. A:a small piece of special paper that you stick on letters to show how much you have paid to send them B: stamp … Step V Speaking T: Well done. In our daily life what should we do when we get into trouble or when we want to buy something expensive and can’t 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? We’ve learnt some expressions for making suggestions. Who’d 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 don’t agree. With her, but mother and her best friend don’t 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: Jane 1. 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. Jane’s best friend 1. We don’t 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 Jane’s mother. on the phone 3. Jane is too young to have a cellphone. Jane’s father 1. If Jane has a cellphone, I can always find out where she is. 2. A callphone will help Jane feel safe. 3. Jane can use a cellphone send messages to her friends Sample discussion Jane: Thank you for taking the time to talk with me. 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 don’t 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, that’s true, but I don’t 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. You’d 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 don’t 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 couldn’t 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 let’s 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 let’s have some fun. How about playing some cards! Step Ⅵ. Summary and Homework T: Today we’ve done some listening and learnt how to describe things. We have also practised describing objects and giving somebody some advice. After class, make up a dialogue with your partner, using these expressions for making suggestions (Pointing to the blackboard)and according to situations we have discussed in class. Besides, do the exercises in Listening and Talking on Page 133 and 134. So much for today. Suggested answers: Listening. Ex.1 What’s the bask of the ISS?
