televisions

Tv is one of the ways to spend our free time. Sometimes it shows good or sometimes bad things.it's good,that there are some documentary films,which show us the life of wild  animals,old civilisation,and the lost world.there is news,which inform us about the things, which are happening all around the world.also tv shows some talk shows,where we can hear the interesting interviews.but there are a lot of violence and debauchery in tv films,even in cartoon.and violence has a bad effect on viewers,eapecially on children and teenagers.they can't understand what is right or what is wrong.
