There are few families in the United States that do not have either a radio or television set. Both of
them have become a necessary part of our daily life, keeping us filled with the news of the day, teaching
us in many fields of interest and making us happy with singing,dancing and acting?
Marconi, the Italian inventor, who gave us the radio, 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 happen. Travelers in out-of-the-way places, ships at sea even astronauts round 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 life of people everywhere. Many programs are now televised in
color.
Perhaps the most modem invention is"Telstar"，a"star"moving round 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 on
TV a motor-car race in Italy , a table tennis competition in Beijing or a volleyball match in Japan as these
events are actually happening!
