the Advantages and Disadvantages of TV
We have to admit that TV has
brought great changes to our life.Almost everyday,we watch all kinds of programs
on TV.We need them as well as enjoy them.TV can amuse people,give us news and
information we want,and expand our horizons.We can also relax ourselves by
watching TV after hard studies or work.Hower,there are two sides to
everything,and TV is without exception.TV also has some
disadvantages.First,spending too much time on it will affect our studies and
work.Second,there are now too many commercials(广告)on TV,which would make us care
more about money,and it's not good for teenagers' growth.Third,sitting in front
of TV too long would do harm to our health.
Therefore,we students
should watch TV in our spare time but not be addicted to
it.
Firstly, you can expand your knowledge by watching TV. As we all know, learning things by TV is much faster than by listening to the radio or just by reading books. For it has colorful pictures as well as wonderful music.
Secondly, you may know anybody you want to know such as famous singers, super stars, scientists and so on.
What’s more, you can go everywhere by traveling programs. Let’s suppose, if you like traveling very much, but you have to work on weekends or holidays, you must be very sad. And now open your TV and it’ll take you to anywhere.
Every coin has two sides. The disadvantages are also obvious. For example, watching too much TV can easily become short-sighted, especially for children and students. To make matters worse, some young students are keen on watching TV so that they give up their studies gradually.
Through above analysis, I think watching TV is a way of studying, it is good for us to watch TV. But when we watch TV, we should make a plan otherwise watching TV will destroy our life.
