单选题Thousands of years ago man used handy rocks for his surgical operations. Later he used sharp bone or horn, metal knives and more recently, rubber and plastic. In the 1960s a new tool was developed, one which was, first of all, to be of great practical use to the armed forces and industry, but which was also to revolutionize the art and science of surgery. The tool is the laser and it is being used by more and more surgeons all over the world. As we all know, light is hot, and any source of light will give warmth. But light is usually spread out over a wide area. The light in a laser beam, however, is concentrated. This means that a light with no more power than that produced by an ordinary electric light bulb becomes intensely strong as it is concentrated to a pinpoint-sized beam. Experiments with these pinpoint beams showed researchers that different energy sources produce beams that have a particular effect on certain living cells. It is now possible for eye surgeons to operate on the back of human eye without harming the front of the eye, simply by passing a laser beam right through the eye-ball. Operations which once left patients exhausted and in need of long period of recovery time now leave them feeling relaxed and comfortable. The rapid development of laser techniques in the past ten years has made it clear that the future is likely to be very exciting. Perhaps some cancers will be treated with laser in a way that makes surgery not only safer but also more effective.

单选题The Norwegian government is doing its best to keep the oil industry under control. A new law limits exploration to an area south of the southern end of the long coastline, production limits have been laid down, and oil companies have not been allowed to employ more than a limited number of foreign workers. But the oil industry has a way of getting over such problems, and few people believe that the government will be able to hold things back for long. Ever since the war, the government has been carrying out a program of development in the area north of the Arctic Circle. During the past few years this program has had a great deal of success. Tromso has been built up into a local capital with a university, a large hospital and a healthy industry . But the oil industry has already started to draw people south, and within a few years the whole northern policy could be in ruins. The effects of the oil industry would not be limited to the north, however. With nearly 100 per cent employment, everyone can see a situation developing in which the service industries and the tourist industry will lose most of their workers to the oil industry. Some smaller industries might even disappear altogether when it becomes cheaper to buy goods from abroad.

单选题A Fred, a very conscientious worker, had one serious flaw: he was clumsy. The poor boy spoiled everything he did and for that reason could never keep a job. He'd had many jobs over the years but only for a few weeks at a time. For six months, Fred was out of employment. Finally, he got a job in a warehouse where many different types of home furnishings were stored. Fred's job was to unpack the merchandise newly arrived from the factory and put each item in its assigned place. The work was only temporary, but after so long with no employment at all it was better than nothing. One morning Fred unpacked a large and quite fragile vase. He picked it up to carry across the warehouse. But he had only walked two steps and he tripped. There was a loud crash as the vase fell from Fred's hands and shattered into a thousand pieces. Fred was called immediately to the manager's office, and he was sure he would be fired. The young man's spirits began to drop. "I'll have to deduct something from your wages every week until the vase is paid for," the manager said sternly. "How much is the vase worth?" Fred asked. "$350." A wide grin spread across the young man's face. "That's wonderful!" he shouted happily. "At last I have a steady job!/
