第一篇Few families in the United States do not have either a radio or a television set. Both of them have become a necessary part of our daily lives, keeping us filled with the news of the day, teaching us in many fields of interest, and making us happy with songs, dances and other performances.
Marconi, the Italian inventor, gave us the radio. He probably didn't know how much his great invention would have done for the world in the years to come. Radio had perhaps done as much as any other communication tool. Things of the world can be reported to people everywhere a few seconds after they happened. Travellers in out-of-the-way places, ships at sea, even astronauts around the earth are able to keep in touch with each other by radio.
Television is another important invention. It lets us see as well as hear the actor. Since its
appearance, TV has done a great deal in the daily lives of people everywhere. Many programmes are now televised in colour.
Perhaps the most modern invention is the "Telstar", a"star"moving around the earth. It makes it possible for the people all over the world to be closer than ever before. Now a family in Chicago can watch a motor car race in Italy on TV, a table tennis competition in Beijing or a volleyball match in Japan as these events are actually happening!
