    have you ever tohught how tv affects the children mind? many people think that it is a great problem nowadays. so, is tv is a cure or a curse? as for me, i think that it helps children to found out something new for themselves.  they found an information that will help them it their future life. tv can also give an opportunity for children for selfeducation.     but there are people who think that tv can be dangerous for children. they say that children don't go anywhere and spend all their day sitting behind the tv set. moreover they think that violence on tv can make children angry and turn them into bad persons. i don't think so because there are not only violence, but also  lots of useful and interesting programs on tv.     to sum up i want to say that the tv is a great thing and it depends on you how to use it.
