First of all, television helps a child to extent his or her range of interests. Children can find out many new things and make many exiting discoveries for themselves. In addition to these practical benefits television improves children's vocabulary, their memory and gives them the opportunity to gain more knowledge. I think it is very essential for a child. Of cause, someone can say that there are plenty of different recourses of information such as books and teachers. But, I think, in our modern world children must learn faster and use all contemporary technology in order to succeed.
Second of all, watching cognitive programs helps children to learn more about wild life, our environment and about the importance of preserving our forest and wild animals that live there.
Scientists say that a child should not watch TV more then 40 minutes successively. For example, my mother always made us have a break after watching TV more then half an hour and let our eyes rest for several minutes before turning on the TV again. I think it is the best solution.
To sum up, I believe that television gives children and all people the opportunity to learn what can not be learn from books. Television and movies in particular allow people to feel the reality and see what they will most likely not be able to see in their lives. Personally, when I was a child I liked to watch cognitive programs about wild animals. Unfortunately, my family had only one TV, but these programs were the only ones we all wanted to watch.
