The twenty first century is a century of technologies, computers and technology. It is well-known that the computer has become one of the main ways of getting information. Some people can’t live without it, but other thinks computers have a bad influence. Whose opinion is right?

 My point of view is the following. Firstly, the computer informs us about various things. Secondly, you can travel to different countries and at the same time sitting in front of a computer screen. It is very comfortable. Thirdly, you can use a distance learning. This is a great leap of progress.

 But some people are against computers. Firstly, they thought that we can work without computers, because it breaks our eyesight. Secondly, we get a lot of unnecessary information, for example — a promotion. It  distracts when you are so busy.

 But I do not agree with this people. To preserve the health, you should: firstly, ventilate the room; secondly, take a timeout. That you do not get useless information, you can change the computer tuner.

 All in all, I want to say that I am for computers. I believe that computers can materially do our work  easier and make people more educated. Our future is in our hands.
