Most of us like watching TV. It has a great influence on our lives and it is one of the most important of getting information. We spend part of our free time TV. Usually we can learn a lot from it. Just think of what we see on TV-news, movies, sports shows, advertisements and so on. They have increased our and changed the way we learn about the world today. But besides these advantages, it has some disadvantages.
For adults (成人), sometimes they watch TV too long. They always stay in the room and be far away outdoor activities. They spend little time doing sports. If the situation goes on, many adults will become weak. So it's for them to control the time of watching TV. Instead, they'd better go out to enjoy different kinds of sports.
For children, some programs on TV are good, there are still some shows that are not proper for them. Not everything on TV has a good influence. Maybe children can't change what is on TV, but they can what they watch. Is that right?
