TV is very important in our life.We can get to know all kinds of events around the world.We can know the weather,information,laws,knowledge and so on.After busy work,we can watch some funny programs to relax
TV benifits us,but sometimes it has bad influence.Some students watch TV day and night.It influences their lessons.Some programs are not good for children.
It is hard to avoid television if you are a normal person. People in the house are usually tuned in to TV. In some homes, the television is perpetually “on” even without anyone watching. It is common for parents and caregivers to use TV as a substitute babysitter. But is TV really worth us watching?
The majority of experts think that a TV culture has bad effects on human beings, and may prevent us from being smart. TV provides no educational benefits for a us. Even worse, it steals time for activities that actually help develop our brain, like interacting with other people and working. We all need to interact with real world people and events, rather than things to see on a video screen.
TV viewing also hurts our ability to focus. According to Speech and language expert Dr. Sally Ward, 20 years of research show that kids who are bombarded by background TV noise in their homes have trouble paying attention to voices when there is also background noise.
