单选题{{B}}第三篇{{/B}} The Iceman On a September day in 1991,two Germans were climbing the mountains between Austria and Italy. High up on a mountain pass,they found the body of a man lying on the ice.At that height(10,499 feet, or 3,200 meters),the ice is usually permanent,but 1991 had been an especially warm year.The mountain ice had melted more than usual and so the body had come to the surface. It was lying face downward.The skeleton(骨架)was in perfect condition,except for a wound in the head.There was still skin on the bones and the remains of some clothes.The hands were still holding the wooden handle of an ax and on the feet there were very simple leather and cloth boots.Nearby was a pair of gloves made of tree bark(树皮)and a holder for arrows. Who was this man?How and when had he died?Everybody had a different answer to these questions.Some people thought that it was from this century,perhaps the body of a soldier who died in World War I,since several soldiers had already been found in the area.A Swiss woman believed it might be her father,who had died in those mountains twenty years before and whose body had never been found.The scientists who rushed to look at the body thought it was probably much older,maybe even a thousand years old. With modern dating techniques,the scientists soon learned that the Iceman was about 5,300 years old.Born in about 3300 B.C.,he lived during the Bronze Age in Europe.At first scientists thought he was probably a hunter who had died from an accident in the high mountains.More recent evidence,how ever,tells a different story.A new kind of X-ray shows an arrowhead still stuck in his shoulder.It left only a tiny hole in his skin,but it caused internal damage and bleeding.He almost certainly died from this wound,and not from the wound on the back of his head.This means that he was probably in sortie kind of a battle.It may have been part of a larger war,or he may have been fighting bandits.He may even have been a bandit himself. By studying his clothes and tools,scientists have already learned a great deal from the Iceman about the times he lived in.We may never know the full story of how he died,but he has given us important clues to the history of those distant times.

"This being the case, physical education is a (62) that has an important place in schools, and is an absolute must (63) we want to do well in maths and other theoretical subjects.

单选题阅读下面这篇短文,短文后列出7个句子,请根据短文的内容对每个句子做出判断。如果该句提供的是正确信息,请选择A;如果该句提供的是错误信息,请选择B;如果该句的信息文章中没有提及,请选择C。 Pubic response to technology often varies in peculiar ways. While biotechnology, for example, gives rise to organized opposition, information technology, which is actually no less invasive(侵害者), no more harmless, is welcomed or, at the least, accepted with comparatively little debate. Information technologies—from computers to communications—have obviously had an overwhelming social impact and their benefits hardly need explanations. But they have also disturbed privacy and threatened civil liberties. Computerized data banks empower bureaucratic authorities by providing easy access to personal information—about credit ratings, social performance, housing and medical histories. They will allow access to genetic figures, providing information about our tendencies to employers, insurers, product advertisers, banks and other institutions that exercise control over our lives. Computerization allows the severe extension of advertising through telemarketing requests that shamelessly intrude our home life. Information technologies have displaced people from jobs and turned potentially skilled workers into low-level computer technicians, computers have facilitated the work of scholars, but also turned them into typists; yet one hears hardly a complaint. They have turned the simple act of buying a plane ticket into an endless manipulation(控制), but we welcome the so-called convenience. They have encouraged new forms of crime and fraud(欺诈), but we describe them with grudging admiration. They have allowed new types of evil weaponry, but we call them "smart bombs". Perhaps the most important, information technologies have extended the power of the mass media, creating unusual possibilities for political manipulation, reducing accountability(有责任,有义务), and changing the nature of political life. It is true that there are critiques(批评) of information technologies from those professionally concerned about their problematic legal, social and political implications. There is a near total absence, however, of organized public concern about technologies with profound and problematic implications.

单选题Japanese Car Keeps Watch for Drunk Drivers A concept car developed by Japanese company Nissan has a breathalyzer-like detection system and other instruments that could help keep drunk or over tired drivers off the road. The car"s sensors check odors inside the car and monitor a driver"s sweat for traces of alcohol. An in-car computer system can issue an alert or even lock up the ignition system if the driver seems over-the-limit. The air odor sensors are fixed firmly and deeply in the driver and passenger seats, while a detector in the gear-shift knob measures perspiration from the driver"s palm. Other carmakers have developed similar detection systems. For example, Sweden"s Volvo has developed a breathalyzer attached to a car"s seat belt that drivers must blow into before the engine will start. Nissan"s new concept vehicle also includes a dashboard-mounted camera that tracks a drivers alertness by monitoring their eyes. It will sound an alarm and issue a spoken warning in Japanese or English if it judges that the driver needs to pull over and rest. The car technology is still in development, but general manager Kazuhiro Doi says the combination of different detection systems should improve the overall effectiveness of the technology. "For example, if the gear-shift sensor was bypassed by a passenger using it instead of the driver, the facial recognition system would still be used," Doi says. Nissan has no specific timetable for marketing the system, but aims to use technology to cut the number of fatalities involving its vehicles to half 1995 levels by 2015. The car"s seat belt can also tighten if drowsiness is detected, while an external camera checks that the car is keeping to its lane properly. However, Doi admits that some of the technology, such as the alcohol odor sensor, should be improved. "If you drink one beer, it"s going to register, so we need to study what"s the appropriate level for the system to activate," he says. In the UK, some research groups are using similar advanced techniques to understand driver behavior and the effectiveness of different road designs.

单选题Lifetime Employment in Japanese Companies In most large Japanese companies, there is a policy of lifetime employment. What this means is that when people leave school or university to join an enterprise, they can expect to remain with that organization until they retire. In effect, the employee gets job security for life, and can only be fired for serious mistakes in work. Even in times of business recession, he or she is free from the fear of being laid off. One result of this practice is that the Japanese worker identifies closely with his company and feels strong loyalty to it. By working hard for the company, he believes he is safeguarding his own future. It is not surprising that devotion to one"s company is considered a great virtue in Japan. A man is often prepared to put his firm"s interests before those of his immediate family. The job security guaranteed by this system influences the way employees approach their work. They tend to think in terms of what they can achieve throughout their career. This is because they are not judged on how they are performing during a short period of time. They can afford to take a longer perspective than their western counterparts. This marriage between the employee and the company—the consequence of lifetime employment—may explain why Japanese workers seem positively to love the products their company is producing and why they are willing to stay on after work, for little overtime pay, to participate in earnest discussions about the quality control of their products.
