    Now, let's think about TV and our life at home. Today almost all the homes have television sets. There are many interesting TV programs that we can enjoy with our family. Well, how many hours do you watch TV every day? You spend a lot of time in watching TV, don't you? It gives us a lot of useful information that we cannot learn at school. On the other hand, we can talk with our family when we watch TV. Sometimes we find that we sit in front of a TV set without thinking anything. It is very important for us to select good TV programs. We must try to make good use of it to make our lives better.
