What’s the difference between a discovery and an invention? Now look at the pictures on page 1. Work in pairs and talk about the three different things, telling them apart and giving reasons.Show the following.1. Which o these pictures show inventions? Does any of them show discoveries?2. Work out two rules that will invention?S1: I think the first two are inventions, i. e. the amphibious car and Stevenson’s “Rocket” while the last picture about the DNA is a kind of discovery. Because the first two products were quite new to people at that time and no one or designed such kind of vehicles before though some others biology because such cells and their structure do exist in living creatures and they found out bya certain scientist and are made known to the public nowadays. So I think adiscovery is something existing before but unknown while an invention is something unknown and not existing before.S2: I think the first two pictures show us great inventions about the transportation because they were invented by people for certain purposes and they some ways. On the other of DNA is a kind of discovery because these special cells exist and function in the body of life all the time no matter who discovers it or when and where it is discovered. In my opinion a discovery is something found out or brought to view now but it was unknown before while an invention is something created or designed by people, which is completely new not only now but in the past.T: Well, from these pictures we can see that there lies differences between a discovery and an invention. There are certain rules or questions you should pay attention to while distinguishing them. Did it exist in the past? Is it created or developed by people? An invention is something that is created by a being, suchas the lightning rod. To the contrary, a discovery merely makes known something that already existed in nature, such as the discovery on the New Continent by Columbia. OK. Let’s go on with some other questions of this part. You may talk with your partner first before we inventions do you know? Describe them to your partner and life today.S1: Adidas 1 is the thinking shoes with a built-in microprocessor that decides chosen by Popular Science magazine as the best recreation invention of 2004.It is very comfortable to wear it all day without worrying about your toes being adjust the snap pictures as discreetly as any spy and, with the push of a few buttons, pop them into an e-mail or upload them to the Web in less thana minute. No wires or to the Web in less than a minute. No wires or computerused to snap pictures of VIPs at private parties, copy recipes from cookbooks at bookstores and even document crimes in progress. But with an estimated 80 million camera phones sold in 2003, 6 million in the U. S. alone− the cat may already be out of the camera bag. Like it or not, these camera phones very popular and widely used by people even today.S3: A kind of robot 2001. On July 2, 2001, the 59-year-old grandfather and retired librarian Robert Tools became the first to get one. It’s be en long since the operation, and Tools’ new walk a city block without stopping and making plans for the future. Though not everybody needs a new artificial so many modern inventions both at that modern discoveries and inventions do people’s life and can always represent the advanced science and technology, so you should to distinguish them and make good use of them.Step II TalkingT: Suppose you are working for a mobile company. It is your job to suggest new ways of developing a mobile. In pairs discuss some new applications of a mobile. Makea list of the ones you like and that seem the most useful. Choose one you bothlike and think will be popular with other people. Now work in groups of four to discuss the question.S1: I suggest the new applications of mobile should be: portable entertainmentplayers, cameras, membership and loyalty cards, guidebooks, maps, tickets, watches, and devices for accessing everything from news to corporate databases.Among them, we like the applications of devices for accessing everything from news to corporate databases. We both think they are useful and will soon be popular with others in the near future because the ability will enable a whole class of workers to rely less on their memory and more on their company’s an d even world’s knowledge maintenance, sales construction, transportation, taxicab drivers, and many other workers spend a great deal of time from offices.Thus, when they need information, they must either their be developed better with 4G to listen to the radio, watch TV, play games, do shopping, chat on the QQ,, surf the internet, control the electrical equipment at the distance, give off do business, and work as intelligent P4 computers. Among them, we like the new application of surfing the internet and doing shopping and we both think they are useful and will soon be popular among youngsters because it is very convenient for people to find various useful information whenever and wherever possible. As there are different kinds of goods to choose fro m online and it’s very funny and exciting to make choices and buy what we need at a reasonable price without going out and bargain with sellers in the markets.…T: Very good. Now get together with another pair to discuss whether your suggestion is a good one. Make a case for your idea. Let the other pair evaluate it. Then swap so that you evaluate their idea. Decide which idea you like better and prepare to explain it. Then present it to the class.S1: I think the first classmate’s expectation that the mob ile phones can do so much, maybe more than they can offer. The mobile phones usually that way. Though it used in some ways but we can do better because every day we to look for and different types of things to do and the smart mobile can make it more convenient for us to achieve our goals in life.…T: Now, I’d like you to discuss in groups and try to tell the other about yourideas and the others who act as the leaders of the company may ask some questions for I’d like some of you to report your group work.Five minutes later.(L=Leader of the company)S: I think the new mobiles can be developed better with 4G to watch TV and do shopping on the internet.L1: Well, advance and try to reduce the cost as much as possible.L2: Are you sure of the security measures of using these mobiles, especially when they are used to shop on the internet.S: Sure. I’ll keep the new mobiles designed so in order that they will give warning messages whenever there is misleading information or dishonesty in selling and buying things on the internet.L3: I think it would be difficult for the new mobile of limited size to be used to watch live broadcast and pick out all sorts of goods on the internet. Have you taken these into consideration?S: Yes. Now, I come to realize that I the mobiles with larger screens, which can make it more convenient and comfortable for the users. Thank you!T: Very good! I can see all of you the presentation. Next I want you to evaluate the ideas using the following criteria. First, do you know about the words, Such as originality and quality argument?S: Yes, originality just means the quality of being new and interesting and quality argument just means different opinions about the quality of the product. T: Quite right! Now let’s look at the crite ria and go on with the next step. Show the followingAfter each group part, add up the scores and award the contract to the winner! T: Next, I’d like to divide you into four teams and the leader of the company will write down the scores according to the criteria while class.Step III SPEAKING TASK (若时间不足，可改为作业)T: Leonardo da Vinci was not only a painter, but a true inventor. Now look at the picture in 1 on page 68. I’d like you to work in pairs and discuss what this invention of Leonardo da Vinci was. Several alternative explanations are provided, but only one is correct. Be prepared to give your ideas to the class with your reasons.S: I think it’s a kind of water slide because we can clearly see the long slide way connecting the water tower, equipment on the roof of the building and the base on the ground. If there is a lack of water down on the ground, the working machine will be used so carry water from the tower above to the ground along the slide way. Just so, this specially fixed machine can also carry water up to store in the tower if the water on the ground is more than needed. This kind of invention is really useful especially in some dry or mountainous areas.T: Good! You are very creative inthinking about the use of the machine in different cases and from this we can see Leonard da Vinci is really a great inventor. He contributed to people’s everyday life besides painting wonderful pictures. Well, let’s go on with Activity 2. Please look at the pictures and read the instructions below, discuss in groups and finish the exercises.Sample answers:Step IV ProjectT: “Creativity is the soul of a nation and an inexhaustible source of a country’s prosperity.” Chinese former President Jiang Zemin said in the speech delivered on November 24 to the scientific and technological community in the Science City of Novosibirsk. As a young generation, every one of us should be creative and inventive in order to contribute more to make our country richer and more beautiful. Now, please look at the project exercise on page 69. I’d like you first read the introductions and then discuss in pairs about the pictures and solutions to the problems. Finally I’d like someone to present your work. One possible solution:S: In this kind of situation, I will shape of or the nuts on the trees into the island to focus the the leaves and wood so that there will be much smoke rising from the fire caused by the strong light and . If I’m not lucky enough to be saved by someone, I would much about and make effective inventions especially in emergency. I am very proud of you and I’m sure you will do more research about the inventions after class until you make them perfect.Step V HomeworkAsk the students to do the following.1. Search for more information about mobiles on the Internet.2. Prepare for the listening part on page 26.。

Unit 3 Inventors and inventions学案Grammar1. The first thing I tried to do was to see if there were products that might help me, but there only seemed to be powders designed to kill snakes. 首先我查看是否有产品能帮助我，但看来只有一种毒杀蛇的药粉。

（P.20）【点拨1】本句中there seemed to be是there be句型的特殊形式，表示“似乎有”。

注意其时态的变化，如：seem to do / seem to be doing / seem to have done 等。

【点拨2】designed过去分词作后置定语，修饰前面的名词powders，表被动。

【考例】“Things ______ never come again!”I couldn’t help talking to myself.（2007，湖南）A. lostB. losingC. to loseD. have lost【解析】答案A。

句意为：“失去的事物不会再回来！”我忍不住自言自语。

本题考查非谓语动词。

因为things和lose之间是被动关系，须用过去分词作定语。

单个的过去分词作定语时一般位于名词之前，但有时为了强调，也可放在名词之后作后置定语。
