Read the text about the role of computers in human life and answer the questions
Man and computer Fifty years ago people didn't even hear of computers, and today we cannot imagine our life without them. Computer technology is the fastest-growing industry in the world. The first computer was the size of a minibus and weighed a ton. Today, its job can be done by a chip the size of a pin head. And the revolution is still going on. Very soon we'll have computers that we'll wear on our wrists or even in our glasses and earrings. The next generation of computers will be able to talk and even think for themselves. They will contain electronic " neural networks ". Of course, they'll be still a lot simpler than human brains, but it will be a great step forward. Such computers will help to diagnose illnesses, find minerals, identify criminals and control space travel. Some people say that computers are dangerous, but it is so, when they turn into obsession and the virtual world substitutes the reality. It is very bad for health to spend a lot of time in front of the monitor. It goes without saying that computers save a lot of time. They seldom make mistakes. It's much faster and easier to surf the Internet than to go to the library. E-mail is a great invention, too. It's faster than sending a letter and cheaper than sending a telegram. Computers are a useful tool. They have changed our life for the better. So why shouldn't we make them work to our advantage?
