Some doctors use magic, some use needles and others use pills. Who are they?
Among the Indians of North America the ‘medicine man’ was a very important per son. He could cure illnesses, and he could speak to the spirits-the supernatural forces that controlled the world.
The Indians believed that bad spirits made people ill. So, when people were ill, the medicine man tried to help them by using magic-he spoke to the good spirits and asked for their help. Many people were cured because they thought that the spirits were helping them. But really these people cured themselves. Sometimes your own mind is the best doctor for you.
The medicine men were often successful for another reason, too. They knew about plants that really can eure illnesses A lot of modern medicines are made from plants that were used by medicine men hundreds of years ago.
For more than five thousand years Chinese doctors have used needles to fight illnes-ses. This method is called aeupnneture (针灸). The doctor studies the sick person care fully. Then he puts needles into that person’s body at the right places for his illness. Chi-nese doctors believe that they can control the body’s natural forces in this way. At first, doctors in the West thought that this was just another kind of magic. Recently, however, they have found out that it is possible to cure many illnesses like this because the needles help the body to produce its own ‘medicines’. In this way the body cures itself.

A branch of computer science cailled artifical intelligence uses programs that help solve problems by using human knowledge and experience. Artificial intelligence systems are al-so called expert systems, which enable computers programmed with great amounts of in formation to think about many possibilities such as diseases that certain symptoms (症状) could indicate and make a dccision for tile treatment.
Computers are used in teaching as well. Programs that perform computer-aided in-struction (CAI计算机辅助教学) are designed to help students at all levels, from ele-mentary school to the university level. The student sits at a computer terminal (终端). The terminaI’s screen displays a question for the student to answer. If the answer is wrong or incumplete, tile computer may ask the student to try again. It then may supply the correct answer and an explanation. CAf is also used in some adult education programs and as part of the employee training programs of some business companies.
One of the most important uses of computers is to communicate information over long distances. They can send information to each other over telephone lines. As a result, computers keep banks, newspapers, and other institutions supplied with up-to the minute hnformation. A computer network consists of many computers in separate rooms, build-ings, cities, or countries, all connected together. Computer networks allow people to communicate by using electronic mail a document typed into one computer and sent to an-other. Such document generally travel in only a few minutes, even if they are being sent over a long distance.
The computer’s ability to share information with other computers over a network linked by telephone lines is a major revolution in telecommunieatitms. The Internet, an international network of computer networks, has spread out since the early 1990’s. The Internet began as.a US network of scientific and military computers in the 1960’s. Now it is an international system for sending and receiving electronic mail, software, and elec-tronic documents and picture files all over the world. The Internet has already cut the cost of long-distance communicaions for many people. In the future it will completely change the way people work. With the lnternet, increasing numbers of people can work at home instead of in their office.
Computers and their programs are the most complex devices in human history, and probably the most useful. Modern industrial societies now depend on them. As comput-ers become more powerful and widespread, computer education must continue to increase also.
