Many things have their own two sides, one is good and the other is opposite; Computers also have two sides. It is good for us to use it well; Otherwise, it will be bad for us.

For us primary school students, computers are both a good thing and a bad thing. It is good because it has many uses, such as: online shopping, convenient for people's lives, Taobao is a good online mall; Learn websites like eagles. Com can also access ... computers are more than that! With computers in the world, people's knowledge level has been greatly improved. Computers also connect the world into a family, making it easier for people all over the world to communicate. How good the computer side is!

However, computers can also bring problems. For example, computer games, because they are very attractive, some weak-willed primary school students are easy to indulge in them, and some skip classes to play, even delaying their studies and getting worse grades. We can see many such examples in the newspaper. What's more, some people lost their lives playing computer games. For example, in an internet cafe in 2006, a middle school student died suddenly because of excitement; In 2007, a primary school student died on the road of rescue because he played for three days in a row. Because playing computer games requires money, some children even steal money and get caught by the public security bureau. What a terrible thing! These are all serious consequences caused by their improper use of computers. How terrible this side of the computer is!

Everything has two sides, but the benefits brought by computers far outweigh its negative effects.

Also, some of his negative effects may not be solved for the time being, but with the development of science, technology will also develop and will eventually be solved.

So we can't just look at the negative effects, and we can't stop using computers because of the negative effects. This is not right. Computers are such things. Its quality depends on how we use them. We should make good use of computers and turn them into good things to serve us!
