考研英语写作:Computers

Computers are playing a more and more important role in modern society. They are already widely used in industry and universities to do extremely complicated work in all branches of learning. They can solve the most complex mathematical problems or put thousands of unrelated facts in order. Because they work accurately and at high speed, they save research workers years of hard work. Besides, they have found applications in business, transportation, education and other fields. Computers have brought about important social changes.

Computers are also entering ordinary families. As computers are small, cheap and easy to operate, more people buy personal computers for themselves. They use computers to control the work of washing machines, TV sets, electrical cookers and appliances. They use computers to process and store all kinds of information, to entertain themselves by playing games on computer. There seems no limit to the application of computer in our lives.

Despite all the advantages, computers can never take the place of human brain. Although computers work much faster and much more accurately than human beings, they can never lead an independent life or make decisions of their own. No matter how capable they are, they are still our servants, not our masters.
