Most people like watching TV．They always watch it at home in the evening and on their holidays．Watching TV is one of the most important activities of the day．TV programs bring the outside world closer(更近的) to people's homes．Some people say the world is smaller than before because of TV．What's going on in other countries? How do people live, work and study in places far away? Are there any good sports games somewhere? What's life in the deepest part of the sea?

If you want to answer these and other kinds of questions, just turn on (打开) the TV and watch it．You can see a lot and learn a lot．Of course people can also learn by reading or listening to the radio (收音机)．But with TV, they can learn better and more easily．Why? Because they can hear and watch, too．

TV helps to open our eyes．TV also helps to open our minds．TV often gives us new ideas．We learn newer and better ways of doing things．
