【正文】 ntific study of mind and how it functions. (Although the findings of sociology and psychology are based on the principles of scientific investigation, they are not exact sciences. ) Humanities include literature, language, history and philosophy. iii. Definition of technology Scientific knowledge applied to practical uses is normally referred to as technology. iv. Illustration of technology Robotics(機(jī)器人學(xué) ) is a branch of technology involving the study and production of manlike machines capable of performing human tasks . People witnessed major advances in medical research, nuclear energy, and space exploration. Video machines (television, video cassette recorder(錄象機(jī) ), video game(電視游戲 ),puterized banking and Inter have all affected our lives in one way or another. Advantages 0f science and technology For example: With the development of puter technology, people can get a lot of information in a few seconds, chat with people they have never met on the Inter, go shopping by pressing a key or a button. While , hightechnology makes it easier for criminals to mit crime.(wars, pollution, new diseases etc.) 5 The consequences of technological innovations have not always been positive. b. Part One Preparation ? Cloudy Days in Tomorrowland ? Step oneDiscuss the following predictions in pairs and pare each predictions with what actually happened. ( PREDICTION REFERENCES) 1) He failed to predict the widespread use of planes. 2) He failed to predict the important role of the submarines have played. 3) He failed to predict the role of the airplane in military affairs. 4) A president of the Michigan Savings Bank failed to predict that the investment in the Ford Motor Co., could earn a large sum of money. 5) Man can now go to the moon on space flight. 6) He, best known for investing the telephone in 1876, also started the Bell Telephone Company. 7) The first puters weighed several tons. 8) He failed to predict the widespread use of puters beginning in the 1980s. 9) Kelvin failed to predict the widespread use of radio in the 20th century. 10) He failed to predict the popularity of TV throughout the world. Step two Divide the whole class into small groups with 5 or 6 students in each. Two groups deal with one problem. Members in each group have different rolesanizer, facilitator, L2 checker, editor and reporter. Give them 15 minutes to predict what kind of changes will take place in the following fields in the next 50 years. Then one in each group reports their predictions avoiding the ones presented. ★ By using ESA teaching method, the teacher engages the students by asking some questions about the puter technology in order to arouse their interest in the discussion. Group one and two ◆ COMPUTER TECHNOLOGY 6 Question： 1. Who could tell us when and where the first puter was made? (In 1946 in America) 2. Who designed it? (The electrical engineer and the physicist in the University of Pennsylvania ) 3. How about its size at that time? (It was very large in size.) 4. How many square meters did it cover? (It covered 160 square meters. Maybe it is five times of our classroom in size.) ◆ Teacher : But in 1949 last century, popular mechanics forecast the development of puter technology, they said puters nowadays perhaps only weigh tons. Of course they failed to predict the quick development in science and technology. 5. Do you know how much a puter weigh today ? (It is small in size ,very light. ) 6. How about its capacity and speed ? (It has large capacity and stores and analyzes information in a few seconds .) ◆ Teacher makes a summary and puts forward another question : Now that we all know where and when the first puter was made, who designed it, and how many square meters it covered. And we also know today’s puter is small in size, and very light. Its capacity is very large and fast in speed. Now let’s work in small groups to have a discussion on “ What changes will take place in Computer Technology in the next 50 years ？ Give your predictions.” （ References） 1) 15 years later, no one uses electronic puter, they will use atomic puter. 2) Computers will e into every home as servants and doctors. 3) More people will have access to puters. 4) People will be able to order all kinds of things through puter. 7 5) A lot of sales clerks will be laid off. 6)The future puter will be smaller in size and faster in speed. 7) Pocket puters will be able to e into being in the near future. 8)The price of puter will be lower. 9) VCD and DVD will disappear because of multimedia puter technology. 10) People have more leisure time because of the puter. 11) Computer will be cheaper than radio. 12) People can receive their education without going to school. 13) Computer will be called light puter. 14) Computer will bee a part of your body. 15) The keyboard of puter will disappear. All the puters will be controlled by voice and mind. After 15 minutes, the teacher asks the students to report their predictions. Later the teacher asks another question: What have we benefited from puter? Students can answer the question freely. ( References) 1. By using puter, we can store and analyze information. 2. we will be able to conquer the space. 3. –controlling machinery 4. Learning sth on the Inter 5. making calculation 6. having a chat on the inter without going out 7. designing sth 8. launching a satellite/ a missile 9. paying for bills 10. curing serious diseases ◆ Teacher: From the answers above, we know we can benefit from puter a lot.
