While their interest is easily led into the theme of the lesson, boy students talked much about new techniques and scientific application in modern cars, whereas girl students paid more attention to the color and the appearance of a car. The vocabulary concerning automobile industry, Global Positioning System and Intelligent Transportation System is unconsciously learnt and used. Real communication played an inevitable role in the improvement of their English. Because of the popularity of expository writing nowadays, when the applied techniques of this type of writing are intentionally found out in different parts of the lesson, they are naturally learnt and acquired. Poor preparation of the new lesson before class is still a serious problem for some students. Appropriate guidance and necessary check is needed.南 阳 理 工 学 院 备 课 讲 稿教学内容批注I. Lead-in by way of discussion.1. How do computers affect our life and culture? 2. What do you think are the advantages and disadvantages of developing the car industry?

Free write the following sentence, and then report to class the reasons for not driving a car. “Even if I could afford a car, I may not actually want to drive one because”. 4. T may move on to Text A by saying: Some scientists and engineers have come up with the idea of a “smart car”. Lets read to find out what this “smart car” can do. .Text Comprehension - Content Questions 1. How important was the automobile industry in the twentieth century? It ranks as among the most lucrative and powerful industries. 2. What will happen to cars and roads in the future?. They will be revolutionized. 3. What can this “smart car” do? d. Smart cars can see, hear, feel, smell, talk, and act; e. They can eliminate most car accidents; f. They can alert the police and provide precise location if stolen; g. They can monitor ones driving and the driving conditions nearby; h. They can alert the driver who feels drowsy; i. They can locate your car precisely and warn of traffic jams. 4. What is telematics expected to achieve in increasing the efficiency and safety of highway transportation? to put smart cars on smart highways 5. What are the advantages of smart highways? d. an environmental boon; e. saving fuel; f. reducing traffic jams; g. decreasing air pollution; h. serving as an alternative to highway expansion. . Text Organization Part I Paras 1-3 New technology will have a dramatic impact on cars and highways in the 21st century. Part II Paras 4-9 With the aid of advanced technology, smart cars will be so designed that they can help eliminate traffic accidents, determine their own precise locations and warn of traffic jams. Part III Paras 10-13 GPS and telematics will make it possible to build smart highways, which will benefit us in more than one way. IV. Something about the text : This is a piece of expository writing. Exposition means expounding or explaining. Things can be explained by definition, classification, comparison and contrast, examples and illustrations, or an analysis of their causes and effects. These methods are very important writing techniques for expository essays.What jumps out first at a browser of this text may be those terms in quotation marks or with capitalized first letters - “blind spot” , Global Positioning System , “atomic clock” , “telematics” and “automated driver” . What do they mean ? How do we find out ?An efficient reader knows . He /She can make a guess based on knowledge of word-formation or knowledge of the word or the context . For example , when the reader comes across “Should you make a serious driving mistake (e.g. , change lanes when there is a car in your blind spot) the computer would sound an immediate warning ”, he or she can guess from the context that a blind spot must be a portion of the road behind a car , which a driver can not observe from the rear-view mirror .What is the Global Positioning System ? From the sentence containing this term (“We already have twenty-four Navstar satellites orbiting the earth ,making up what is called the Global Positioning System .”), we know it is a service linked with a satellite . From the following sentence we know its function (“They make it possible to determine your location on the earth to within about a hundred feet .”) What is an atomic clock ? The answer is found in exactly the same sentence . It vibrates at a precise frequency , according to the laws of the quantum theory .We can guess the meaning of “telematics” from its word formation . The prefix “tele-” means “distant”, the suffix “-matics” may be the end part of “informatics” . Then the sentence in the text - “GPS is actually but part of a larger movement , called telematics”- tells us more about it .What is an automated driver ? Sentences directly following the term give a detailed explanation - “The plan calls for computers , aided by thousands of three-inch magnetic spikes buried in the highway , to take complete control of the driving of cars on heavily trafficked roads . Cars will be bunched into groups of ten to twelve vehicles , only six feet apart ,traveling in unison ,and controlled by computer .”V. Homework assignment 1.Previewing the words and phrases2.

It provides jobs for millions of people, generates billions of dollars in worldwide revenues, and provides the basis for a multitude of related service and support industries. Automobiles revolutionized transportation in the 20th century, changing forever the way people live, travel, and do business. The automobile has enabled people to travel and transport goods farther and faster, and has opened wider market areas for business and commerce. The auto industry has also reduced the overall cost of transportation by using methods such as mass production ( making several products at once, rather than one at a time ), mass marketing (selling products nationally and globally rather locally_, and globalization of production (assembling products with parts made world-wide). Between 1886 and 1898, about 300 automobiles were built, but there was no real established industry. A century later, with automakers and auto buyers expanding globally, automaking became the worlds largest manufacturing activity, with more than 53 million new vehicles built each year worldwide.Automobile manufacturers are among the largest companies in the world. These corporations are often multinational. These companies often share parts, or use parts made in foreign factories. The U.S. automobile industry produced 16.8 million vehicles in 1999. The three major automobile manufacturers in the United StatesGeneral Motors Corporation, Ford Motor Company, and DaimlerChrysler（戴姆勒-克莱斯勒）AGprovde three-fourths of the industrys total direct employment in the United States. At the start of the 21st century, the trends of global trade and manufacturing flexibility continue. Computerization continues to be a major part of auto design and manufacture, as do the search for alternative fuels and more efficient automobile designs.Global Positioning System (GPS): space-based radio-navigation system, consisting of 24 satellites and ground support. GPS provides users with accurate information about their position and velocity, as well as the time, anywhere in the world and in all weather conditions. GPS determines location by computing the difference between the time that a signal is sent and the time it is received. GPS satellites carry atomic clocks that provide extremely accurate time. The time information is placed in the codes broadcast by the satellite so that a receiver can continuously determine the time the signal was broadcast. The signal contains data that a receiver uses to compute the locations of the satellites and to make other adjustments needed for accurate positioning. The receiver uses the time difference between the time of signal reception and the broadcast time to compute the distance, or range, from the receiver to the satellite. The receiver must account for propagation delays, or decreases in the signals speed caused by the ionosphere and the troposphere. With information about the ranges to three satellites and the location of the satellite when the signal was sent, the receiver can compute its own three-dimensional position. As of March 1998, 24 GPS satellites were in operation. Replenishment satellites are ready for launch, and contracts have been awarded to provide satellites into the 21st century. GPS applications continue to grow in land, sea, air, and space navigation. The ability to enhance safety and to decrease fuel consumption will make GPS an important component of travel in the international airspace system. Airplanes will use GPS for landing at fogbound airports. Automobiles will use GPS as part of intelligent transportation systems. Emerging technologies will enable GPS to determin
