LISTENINGIntroduction The students will hear two inventors describe their new inventions to a patent officer. After listening to each inventor, the students are asked to infer why the patent officer doesnt want to give the inventor a patent.Instructions Explain the scenario to the students and ask them to read the questions before you play the tap_. After playing each part, check the answers and ask the students to find whats wrong with the inventions.LISTENING TEXT:Part 1(At the patent office.)J: Frank Jones, an inventor P: the patent officerP: Good morning.J: Good morning. My name is Frank Jones, and I have a great idea for a new invention.P: I see. Can you explain what it is?J: Yes. Oh its great! Its an invention that will change the world. Listen: cars and buses are good means of transportation, right? But they are expensive and noisy, and they pollute the air. Imagine a new means of transportation that lets people travel without a sound, that doesnt need any fuel, and that doesnt pollute the air.P: Hmm, sounds interesting. Go on, please.J: Well, my invention is a vehicle with two wheels instead of four. It doesnt have an engine; instead, you simply push these things here with your feet. P: Ah, excuse me, but perhaps .J: No, no, look! You can use it to go to work, and it is so small that you wont have any problems finding a place to park. And it is cheap -less than three thousand yuan! Isnt it great? You also get exercise by riding it and its fun.P: Excuse me!J: And best of all, it . what?P: Im sorry, Mr. Jones, but I cant give you a patent for this invention.Part 2B: Jack Butler, an inventor P: the patent officerB: Good morning. My name is Jack Butler. Id like to tell you about my new invention.P: OK. Please explain what it is and how it works. B: Sure. Ive been working on this idea for a long time and its finally ready. I got the idea when I saw a woman carrying her bags home from the supermarket. I noticed that the bags were so heavy that she had to stop and rest several times on the way. Now, Ive had the same problem, too, and I thought Id do something about it.P: So how did you solve this problem?B: Ah, its quite simple, really. We all know that things float in water, right?P: Yes, but I dont see how.B: So Ive built these large buckets, see, and all you have to do is put your bags in the buckets and they will float. No more carrying those heavy old bags. Theyll just float along.P: Yes, but .B: Oh, I know, I know, youre wondering well, wont the groceries get wet? Dont worry, Ive thought of that. Just tie the bags up before you put them in the buckets, or use these special bags that e with the buckets.P: Mr. Butler!B: Yes?P: Its not the water Im worried about.B:No?P: No, you see, theres another, more serious, problemAnswers to Exercises 1:1 The new invention is clean and cheap.2 Its a vehicle that doesnt need an engine or fuel.

Imagine how nice and clean our cities would be if we didnt have all the air pollution from cars. A: Yes, it does sound good. How does it work?B: Well, I cant explain the details, but it uses a new kind of engine that can turn water into energy. This new engine is a bit expensive, and the cars wont be able to drive very fast, but I think it will bee cheaper with time. It is a new way of producing energy, so we will have to build new cars. It cant be used for normal cars.A: I see. What about your invention?C: I have invented a machine that makes it possible for people to know the future.A: That sounds incredible! How does it work?C: Its a small puter that is connected to your brain. It uses everything you know, and all the information on the Internet. Then I use a special equation to guess what will happen next. The machine is right almost 90% of the time.A: How would people use it?C: Well, lets say you want to know what questions will be on the maths test next week. You ask the puter to guess and it will predict the questions. Or, if you want to know what will happen two weeks from now, you just type in the date and the pute: will describe what will happen to you.D: Excuse me, may I tell you about my new invention? A: OK.D: I have invented a flying bicycle. This invention can help people get around in crowded cities.A: Whats it made of?D: The bicycle is made of very light plastic.

READING Introduction The text describes the thinking strategies that creative thinkers use and explains how these strategies work. As paragraph one notes, great thinkers seem to have little in mon - they have different backgrounds, IQ, and education. What they do have in mon are the thinking habits outlined in the reading.1 Think outside the box. Our ability to e up with good ideas or solutions is limited by the way we normally think. Creative thinkers try to break away from their normal patterns of thought - the box - in order to solve difficult problems. They also realize that partial answers and even failures help us better understand a problem.2 Take another look at it. Our perception of things can also be a limiting factor. If we only view a problem in one way, we may not be able to solve it. Great thinkers like to use different ways to look at a problem - using pictures, words, numbers, models etc.3 Make connections. Many important inventions were the result of an inventor making unusual parison and connections. Creative thinkers make use of their knowledge as well as their imagination. If we connect new information only with whats logical or normal, we limit our creativity.4 Keep trying. The more ideas an inventor examines, the more likely he or she is to find a good one. Great inventions are rarely the result of a sudden flash of genius, but rather tend to e after a long series of trial and error. Many famous inventors forced themselves to keep thinking and making new inventions even when they did not feel inspired.We can all achieve more if we develop our creativity. By trying the thinking strategies of inventors and scientists, we can bee better problem-solvers and learners.4.

INTEGRATING SKILLS ReadingIntroduction The reading is a continuation of the unit theme, ie the relationship between ideas, inventions, and society. The reading gives examples of scientific metaphors and discusses how the way we talk about-and think of-new inventions influences our understanding and actions.There is no doubt that huge advances have been made in science ,and technology, but has human thinking really changed. Many of the new inventions we use in our lives are really just better tools for doing the same things we have always done.We use metaphors to talk about new inventions. monly used metaphors include memory, store, and cut and paste. These metaphors are useful because they help us quickly understand new technology and its uses, but they are also misleading since they misrepresent reality. That may in itself not be very serious, but it may also limit our ability to use new technology to its full potential.At present, technological development is occurring at ,such a high pace that it may be difficult for us to deal with it. In the past, new theories and inventions did not appear as frequently and we had more time to adapt. Today, science and technology are advancing faster than ever. Will human thinking keep up?Answers to the questions:1 Scientific metaphors like memory and cut and paste are useful because they help us understand and use new technology. They may limit our thinking by keeping us from using the new technology in new ways.2 Various answers are possible. Possible examples include surf the Internet, print, delete, file etc. Sample responses to the follow-up questions:If I use surf the Internet, it. helps me understand that I am moving around on an ocean of information-I jump from site to site like a surfer riding on a wave. Using file makes it easy to understand that a puter file is like a file where I can store pages. I think the words are useful, but since I dont know much about surfing, maybe another word would be better. Perhaps travel would be better, because travel suggests that I move around and visit different places. Another advantage is that I know that you have to be careful when you travel, and that you sometimes need money and a passport.TechnologyUsageputerUsed as a typewriter / tape recorder / VCD player / notebook / calendar / telephone / calculator.The InternetUsed as a library / magazine / TV / telephone / bank / store.CellphoneUsed as a telephone / watch / calendar / camera / puter.4.
