As the development of technology, we are leading a more comfortable life than before. Computers are now considered one of the greatest inventions in the 21st century. It is known to us all that we can use the computer to relax, to search the information, to entertain, and so on. Spontaneously, it is because of the computers that we can keep in touch with our friends. Although computers are convenient to our live, yet there are some disadvantages of them. Recently, it is reported on TV that many middle school students are addicted in computer games. Their parents were very regretful about that and all of them thought " Having not been computers in this world, their children wouldn't have been addictive in computers". Every coin has two sides and so as the computers. Therefore we should be very careful when we are using the computers, because although it can bring us convenience, it will bring us to the danger.
