17、or later ones. With inventions turning up all the time, our world is always taking on a new look. But do you know what an invention is? S1: The creation of something new. S2: A creation (a new device or process) resulting from study and experimentation.S3: The creation of new things. Ask the student

18、s to talk about the pictures with the teachers help, and then discuss the first two questions. T: And what is a discovery? Whats 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 gi

19、ving reasons.Show the following. 1. Which of these pictures show inventions? Does any of them show discoveries?2. Work out two rules that will help you decide what is a discovery and what is an invention? S1: I think the first two are inventions, i.e. the amphibious car and Stevensons “Rocket” while

20、 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 had ever seen or designed such kind of vehicles before though some others had made similar cars or machines which had less functions and advantages as these two. I

21、think the picture about the DNA is a kind of scientific discovery in biology because such cells and their structure do exist in living creatures and they have been found out by a certain scientist and are made known to the public nowadays. So I think a discovery is something existing before but unkn

22、own while an invention is something unknown and not existing before. S2: I think the first two pictures show us great human inventions about the transportation because they were invented by people for certain purposes and they had special advantages and could satisfy peoples needs in some ways. On t

23、he other hand the third picture showing the formation 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 b

24、ut 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

25、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 human being, such as the lightning rod. To the contrary, a discovery merely makes known something that already existed in nature, such as the discove

26、ry on the New Continent by Columbia. OK. Lets go on with some other questions of this part. You may talk with your partner first before we have a check five minutes later. Show the following.

29、te.

30、ctures of friends, family, babies and pets. But they have also been used 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. alonethe cat may al

31、ready be out of the camera bag. Like it or not, these camera phones have been very popular and widely used by people even today.S3: A kind of robot heart called AbioCor was invented in 2001.

Though not everybody needs a new heart, hundreds of thousands eventually may. Nor will an artificial heart rid the world of sickness or p

33、overty or terror. But sometimes it really helps.T: Very good! I am glad to see that all of you have known so many modern inventions both at home and abroad and you have thought a lot about them. Its certain that modern discoveries and inventions do have great effects on peoples life and can always r

34、epresent the advanced science and technology, so you should learn to distinguish them and make good use of them.Step 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. Make a list of t

35、he ones you like and that seem the most useful. Choose one you both like 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 entertainment players, cameras, member-ship and loyalty cards, gu

36、idebooks, 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 be

37、cause the ability will enable a whole class of workers to rely less on their memory and more on their companys and even worlds knowledge maintenance, sales, construction, transportation, taxicab drivers, and many other workers spend a great deal of time from offices. Thus, when they need information

38、, they must either have it in their heads or stop what they are doing and make a phone call.S2: I think the new mobiles can be developed better with 4G to listen to the radio, watch TV, play games, do shopping, chat on the , surf the internet, control the electrical equipment at home in the distance

39、, give off harmless rays and be used as computers with special operating systems which can do business, have fun and work as intelligent P4 computers.

40、oungsters 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 from online and its very funny and exciting to make choices and buy what we need at a reasonable price without going out and bargain w

41、ith 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 prese

42、nt it to the class.S1: I think the first classmates expectation that the mobile phones can do so much, maybe more than they can offer. The mobile phones usually have limited size and capacity. So I think it will take time before the mobiles are designed to meet his needs. S2: I think its practical a

43、nd meaningful for the second classmate to develop the mobiles in that way. Though it has been used in some ways but we can do better because every day we have much information 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

47、onesty 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 have to design th

48、e 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 have done a good job in the presentation.
