к высказываниям участников).
Текст. Computers.
Computers have become an important part
of our everyday life. We can do almost everything with the help of computers.
It has become easier to edit and print documents. The World Wide Web allows us
to access the latest news very quickly. Interaction with the world is a great
advantage of a computer. Besides, it is a great chance to practice your
English. Computers help us to our homework and to make reports. The negative
side lies in the fact that we can become addicted to it because we sometimes
don’t need to go to the library for information. Some pupils find virtual
reality more attractive than real one. Besides, there are hikers and computer
criminals. One of them, Vladimir Levin from St.Petersburg, was able to break
into Citibank’s computers in the USA. He moves more than 10 million dollars to
other banks all over the world.
To sum up, it’s impossible to predict now what the Internet will be like in
future or how it will change our lives. But we must admit that the World Wide
Web offers people great opportunities, and we must try to make the best use of
it.
