    I. Brief Statements Based on the Unit
                The activities of this unit, including Warming-up, Listening,
                Speaking, Reading and Writing, center on the subject-news 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 them-not 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 Grammar-the 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.
                Ⅱ. 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.
                 Ⅲ. 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 on
