I like watching TV very much, for I think it has many advantages . First of all, watching TV is a good rest(;). After a day of hard work, we need a good rest. Watching TV can make our mind and body not tired any more because of the pleasant music and TV plays. Besides , watching TV is entertaining . There are many kinds of entertainment, such as sports activities, singing and dancing, plays and films all over the world at every time. It's not possible  for us to go to every place to enjoy all the activities within a short time. We need at least over ten hours to fly from New York to Paris, a week by train from Beijing to Moscow and an hour to drive from Queens District to Manhattan District.)But within just one second, TV can bring us from an NBA game in New York to a fashion show in Paris by changing the channels . Most importantly, watching TV is educational. Our children can learn every kind of subjects through the educational programs and the special reports on TV, and it's easy for them to learn Chinese from a Chinese teacher in Beijing and to learn Russian lessons from a Russian teacher in Moscow. At the same time, a teacher can teach quite a lot of students without a large classroom. The writer writes the text to   _  .
