Many people are worried that television has caused a lot of effects on American children.
For one thing,some teachers feel the television has taken away the child's abilities to learn mental pictures.
As a result,children cannot understand a simple story without seeing pictures.
Secondly,too much TV tends to cause children to withdraw from real-life experience.
Thirdly,they cannot understand the frustration of learning.
Finally,the most serious result is the impact of television violence on children who have thought of it as everyday thing.
