Computer

Computer is one of the most important inventions in 10 centory . It’s hard to do lots of thongs without computers. If one day computers disappeared ,The world perhaps be in a mass.
Computers can control the traffic light, can detect the wheater, and computers can look our home when we are away from home. We use computers to control things need to be controlled. We use computers to observe what cannot be detected by human beings. We use computer to calculate large and complex things…….It almost could be used in every thing in our life
For students computers are so important that they can’t live without computer. Take me for example. I know what time to go to school on computers. I type homework and search data on computers. When I want to take a break, I’ll push the start button then liten to some music or see BBS on computer. When I want to play tennis beter, I even see some teaching vedio on computer.
Although computers are so good, there’s some bad of computer. I heard some students playing computer games enthusiastically and didn’t study. They are live in the game world and forget what is the most important thing to do. And we heard that there are so many internet crimes. Chatting on internet is also easily sawn.That’s not good.
Computer is a very special tool. It can make this world better, but it can also make harms. It’s all depends on what way to use. It can be a crime tool, and it can help police a lot. It can be a marfin that students stay in front of it playing game, and it can also be a convenient thing to help people get the latest information. If everybody knows that, this world will become better and better because of computer.
