单元整体教案NSEFCII-U02(Thefirstperiod)I. Brief Statements Based on the Unit The activities of this unit, including Warming-up, Listening, Speaking, Reading and Writing, center on the subjectnews and the media, which are connected with our life closely. It provides the students an opportunity to learn the language in using it. By talking about news and the media, the students get more knowledge about themnot only know about the important parts they play in learning about the world, but also the ways they are written and made. The students must be very interested in this subject. This way, they can learn the language points easily and freely. They will not only learn some useful words and phrases about news and the media, but also learn to express opinions. Besides, the study of the Grammarthe Past Participle can help the students use the language more exactly. By finishing each task provided in the textbook and the workbook, the students skills to use language can be well developed. . Teaching Goals 1. Talk about news and the media. 2. Practise expressing opinions. 3. Learn about the Past Participle (1): used as Attribute and Predicative. 4. Write a comparison paragraph. . Teaching Time: Four periods IV. Background Information 1. RADIO In ancient times the only way that men could send messages from village to village was on foot. When men learned to use the horse, communication became much quicker. However, compared to the modern world communication was still quite slow. Many parts of the world had no knowledge of events in other places. Later, the post was introduced and horse riders carried letters. This meant that communication was further improved. Horses drawn coaches could move people from town to town in quite a comfortable way. At the beginning of the last century the steam train was invented and for the first time really fast communication became possible. Not only could letters be sent easily from one part of a country to another, but travel was made easy, too. At about the same time, steam ships helped communication between countries. The invention of the telegraph in the middle of the last century further increased the speed at which messages could be sent. In this system electrical signals, in code, are sent along metal wires. These signals travel so fast that they could go nearly eight times round the world in one second. A special device is needed to send the code. At the other end another device is used in order to receive the code. By this method messages can be sent over distances of several hundred kilometres. With the invention of the telephone the human voice could be sent over long distances. Because of this the telephone system replaced the telegraph for quick communication over long distances. The telegraph is still used, however, by newspapers in order to send news and for other purposes too. At the beginning of this century radio was invented and in a few years communication was again improved. The main difference between radio and telephone is that radio uses no electrical signals which travel long distances along wires. Instead invisible waves, moving at the same speed as electrical signals, are used. A few years ago there were not many radio stations in the world. Today there are many hundreds of radio stations broadcasting in different languages and in all countries. The invisible radio waves can easily travel from one country to another. This means that listeners in one country can listen to programmes broadcast from another country. In this way information travels from country to country. Radio is often used by policemen to communicate with one another. In addition, police forces in one country can communicate with those in other countries in order to catch criminals. Ships at sea use radio so that they know exactly where they are. Aeroplanes use radio for the same reason and this makes it easier for them to find their way from place to place. In the modern world there are many methods of communication. As well as radio there is television, for example. This enables information in the form of a picture to be broadcast from one place to another. Radio is often used as part of a telegraph system where distances are very large. Of the many modern methods of communication, radio probably remains the most important. 2. How the Program Is Broadcast?We turn on the radio and a program comes to us from a broadcasting station miles and miles away. We know that words and music themselves havent traveled all that distance through space, but something certainly is bringing the program from the station. What is this silent carrier? The answer is radio waves. We can not see radio waves or feel them or even hear them. In fact, nobody knows exactly what they are. But we do know that they are made by electricity, and we have learned how to use them. At the broadcasting station people talk or sing, instruments (乐器) play, doors slam(砰) ,and all of these make sound waves. The sound waves reach the microphone, and here they are changed into electricity. Then from a tall tower called the broadcasting aerial (天线) ,electricity sends radio waves. The waves travel in every direction, and some of them reach our radio aerial. Now a wonderful thing happens. The radio waves start an electricity current (电流) in our aerial like the one that was first made in the broadcasting station. Finally, the loudspeaker in our set changes electricity into sound, and we hear the program. The First Period Teaching Aims: 1. Learn and master the following words and phrases: media, reliable, fire, face, difficulty, elect, go up, burn down, injure 2. Practise expressing opinion using the following: What do you think of? Whats your opinion? Why do you choose? Perhapsis more important. I would rather choose. I dont think we should choose Maybe it would be better to choose Our readers want to know about 3. Talk about news and the media. 4. Train the students listening and speaking abilities. Teaching Im
