People have different opinions on the effect of television on children．
Some mink that it is good for children to watch TV while others believe that
television is bad for children．In my opinion，most of the effect TV has on
children is bad．
By the time children reach school，they have spent up to one-third of their waking hours in front of the television．Because they just sit back and let things happen to them while watching TV，they become passive．As we all know,children are inventive and they have the ability to imagine a whole world of their own. But what happens when their imagination is not needed,when TV does all the imagination for them? Obviously, these kids are not going to grow up as inventive and imaginative as their parents, for they have been robbed of creative impulses by television watching.
On one hand, TV watching also forces kids into becoming consumers and then wicks them. They are surrounded by ads for dangerous toys, mind-less games, and unhealthy foods. They force their parents to buy them, for the children themselves ate not wise enough to detect the falsity of so much ad-vertising. On the other hand ,by watching too much TV, children are over ex-posed to violence. They watch programs like murders, fights and many other crimes for hours every week, with no adult around to tell them that life is not like that. The effect of the heavy dose of violence is to suggest kids that vio-lence is an ordinary way of life, and that slugging, shooting and cheating are ways to succeed.
The total effect of TV on children is dangerous. It is time for parents to take charge and supervise their children's play instead of parking them by the
tube and hoping it will act as a baby-sitter. The influence of TV is so impor-tant that parents will have to be on their guard to make sure that their children are not being harmed by exposure to it.
