Television has a huge influence on our lives. It is one of the most important ways of getting information. People spend part of their spare time watching television, and much of what they learn comes from it.
What we see on TV — movies，news shows, sports shows, advertisements and so on have increased our knowledge and have changed the way we learn about the world today. However, not everything on TV is true.
Most of the viewers (观众) are children. Television sometimes is like a baby-sitter. It spends more time with children than parents do. But it keeps them in the living room away from healthy outdoor activities. They spend less time playing soccer or walking in the park or playing games in the yard.
Of course, there are some programs on TV that are good for children. But there are also some shows which are bad. Children should not watch unhealthy shows. Maybe we can't change what is on TV, but we can choose what we watch. Do you agree?

Television has taken the place of schools as the main educator(教育者) in America. There are several reasons for this. First, there is the number of hours. While Americans spend about 13,000 hours in schools, they spend 15,000 to 16,000 hours in front of a TV set. Second is the age at which viewers(观看者) start watching TV. People start watching and understanding TV at about the age of 3, which is several years before they start to do school work. Finally, there is the number of viewers. About 90,000,000 young people are attending school, but most of the Americans watch TV every day. It seems, then, that TV shows are taking the place of teachers and professors as the educators in America.
