单选题 Several years ago I was teaching a course on the philosophical assumptions and cultural impact of massive multi-user online games at Williams College. The students in the course were very intelligent and obviously interested in the topic. But as the semester progressed, I began to detect a problem with the class. The students were working hard and performing well but there was no energy in our discussions and no passion in the students. They were hesitant to express their ideas and often seemed to be going through the motions. I tried to encourage them to be more venturesome with tactics I had used successfully in the past but nothing worked. One day I asked them what was or, perhaps better, was not going on. Why were they so cautious and where was their enthusiasm for lean, g? They seemed relieved to talk about it and their response surprised me. Since pre-kindergarten, they explained, they had been programmed to perform well so they could get to the next level. They had been taught the downside of risk and encouraged to play it safe. What mattered most was getting into a good elementary school, middle school and high school so that they would finally be admitted to a top college. Having succeeded beyond their parents' wildest expectations, they did not know why they were in college and had no idea what to do after graduation. In today's market-driven economy we constantly hear that choice is the highest good and that competition fuels innovation. But this is not always true. Choice provokes anxiety and competition can quell (压制) the imagination and discourage the spirit of experimentation that is necessary for creativity. In a world obsessed with ratings, well-meaning parents all too often train their children to jump through the hoops they think will lead to success. This was a bad bet—the course many young people were forced to take has not paid off. The lucrative jobs they expected as a reward for years of hard work have vanished and show little sign of returning in the near future. The difficult truth is that their education has not prepared them for the world they face. Though many young people have become disillusioned with Wall Street and all it represents and would like to pursue alternative careers, they have neither the educational nor financial resources to do so. The situation is critical—colleges and universities must be reformed in ways that allow students to develop the knowledge and skills they need for creative and productive lives. And parents must give their children the freedom to explore possibilities they never could have imagined.

单选题Imagine eating everything delicious you want with none of the fat. That would be great, wouldn"t it? New "fake fat" products appeared on store shelves in the United States recently, but not everyone is happy about it. Makers of the products, which contain a compound called olestra, say food manufacturers can now eliminate fat from certain foods. Critics, however, say the new compound can rob the body of essential vitamins and nutrients and can also cause unpleasant side effects in some people. So it"s up to consumers to decide whether the new fat-free products taste good enough to keep eating. Chemists discovered olestra in the late 1960s, when they were searching for a fat that could be digested by infants more easily. Instead of finding the desired fat, the researchers created a fat that can"t be digested at all. Normally, special chemicals in the intestines (肠) "grab" molecules of regular fat and break them down so they can be used by the body. A molecule of regular fat is made up of three molecules of substances called fatty acids. The fatty acids are absorbed by the intestines and bring with them the essential vitamins A, D, E, and K. When fat molecules are present in the intestines with any of those vitamins, the vitamins attach to the molecules and are carried into the bloodstream. Olestra, which is made from six to eight molecules of fatty acids, is too large for the intestines to absorb. It just slides unchanged through the intestines without being broken down. Manufacturers say it"s that ability to slide unchanged through the intestines that make olestra so valuable as a fat substitute. It provides consumers with the taste of regular fat without any bad effects on the body. But critics say olestra can prevent vitamins A, D, E, and K from being absorbed. It can also prevent the absorption of carotenoids (类胡萝卜素), compounds that may reduce the risk of cancer, heart disease, etc. Manufacturers are adding vitamins A, D, E, and K as well as carotenoids to their products now. Even so, some nutritionists are still concerned that people might eat unlimited amounts of food made with the fat substitute without worrying about how many calories they are consuming.

单选题{{B}}Passage Five{{/B}} The Vikings have left many traces of their settlement which are still visible today. Archaeology provides physical evidence of their conquests, settlement and daily life. The study of place names and language shows the lasting effect which the Viking settlements had in the British Isles, and DNA analysis provides some insights into the effect the Vikings had on the genetic stock of the countries where they settled. All of this provides valuable information, but the only reason that we have an idea of the "Vikings" as a people is their appearance in the written sources. Unfortunately, the value of the written evidence is limited. Not a lot of evidence survives, and much of what we have is either uninformative or unreliable. Many popular ideas about Vikings are nineteenth-century inventions. Others are the result of early historians accepting sources which modern scholars now regard as completely unreliable. In Scandinavia the Viking Age is regarded as part of prehistory because there are practically no contemporary written sources. Even in western Europe, the Viking Age is often seen as part of the "Dark Ages", from which comparatively few historical records have survived. Surviving accounts of Viking activity were almost exclusively written by clergymen (神职人员). These monastic chronicles (编年史) outline broadly what happened, at what date. There are also sources of a more directly religious nature, such as the much-quoted letters of Alcuin, and Wulfstan's famous "Sermon of the Wolf ", both of which chose to interpret the Viking raids as God's punishment on the Anglo-Saxons for their sins. Even the chronicles reflect the fact that the Vikings often attacked monasteries for their wealth, which created an obvious bias against them, and the hostile tone of these contemporary accounts has done much to create the popular image of Viking atrocities. However, modern historians have noted that the same sources show Christian rulers behaving equally unpleasantly, but without being condemned on religious grounds. We tend to think of the Vikings as a race of Scandinavian warriors, but the reality is more complex. Raids on the British Isles and the coasts of France and Spain were the work of Vikings from Norway and Denmark. The word Viking means one who lurks in a "vik" or bay, in effect, a pirate. The word "Viking" has come to describe a whole new age in Europe between about 800 and 1150. This is despite the fact that Vikings were not just pirates and warriors but also traders and colonists. But at the start of the Viking Age in the last decade of the 8th century, loot and adventure were the main goals of the Norwegians who raided in Scotland and Ireland and of the Danes who attacked England. Gold and silver treasures accumulated by the great monasteries could be converted into personal wealth and thus power, and captives could be sold as slaves. What better way for the young sons of good families to earn their way and see the world?

单选题On a weekday night this January, thousands of flag-waving youths packed Olaya Street, Riyadh's main shopping strip, to cheer a memorable Saudi victory in the GCC Cup football final. One car, rock music blaring from its stereo, squealed to a stop, blocking an intersection. The passengers leapt out, clambered on to the roof and danced wildly in front of the honking crowd. Having paralyzed the traffic across half the city, they sped off before the police could catch them. Such public occasion was once unthinkable in the rigid conformist kingdom, but now young people there and in other Gulf states are increasingly willing to challenge authority. That does not make them rebels: respect for elders, for religious duty and for maintaining family bonds remain pre-eminent values, and premarital sex is generally out of the question. Yet demography is beginning to put pressure on ultra-conservative norms. After all, 60% of the Gulf's native population is under the age of 25. With many more of its citizens in school than in the workforce, the region faces at least a generation of rocketing demand for employment. In every single GCC country the native workforce will double by 2020. In Saudi Arabia it will grow from 3.3m now to over 8m. The task of managing this surge would be daunting enough for any society, but is particularly forbidding in this region, for several reasons. The first is that the Gulf suffers from a lopsided labor structure. This goes back to the 1970s, when ballooning oil incomes allowed governments to import millions of foreign workers and to dispense cozy jobs to the locals. The result is a two-tier workforce, with outsiders working mostly in the private sector and natives monopolizing the state bureaucracy. Private firms are as productive as any. But within the government, claims one study, workers are worth only a quarter of what they get paid. Similarly, in the education sector, 30 years spent keeping pace with soaring student numbers has taken a heavy toll on standards. The Saudi school system, for instance, today has to cope with 5m students, eight times more than in 1970. And many Gulf countries adapted their curricula from Egyptian models that are now thoroughly discredited. They continue to favor rote learning of "facts" intended to instill patriotism or religious values. Even worse, the system as a whole discourages intellectual curiosity. It channels students into acquiring prestige degrees rather than gaining marketable skills. Of the 120, 000 graduates that Saudi universities produced between 1995 and 1999, only 10,000 had studied technical subjects such as architecture or engineering. They accounted for only 2% of the total number of Saudis entering the job market.
