单选题Directions: In this part of the test, there are six short passages. Read each passage carefully, and then do the questions that follow. Passage One The biggest problem facing Chile as it promotes itself as a tourist destination to be reckoned with, is that it is at the end of the earth. It is too far south to be a convenient stop on the way to anywhere else and is much farther than a relatively cheap half-day's flight away from the big tourist markets, unlike Mexico, for example. Chile, therefore, has to fight hard to attract tourists, to convince travelers that it is worth coming halfway round the world to visit. But it is succeeding, not only in existing markets like the U.S.A and Western Europe but in new territories, in particular the Far East. Markets closer to home, however, are not being forgotten. More than 50% of visitors to Chile still come from its nearest neighbor, Argentina, where the cost of living is much higher. Like all South American countries, Chile sees tourism as a valuable earner of foreign currency, although it has been far more serious than most in promoting its image abroad. Relatively stable politically within the region, it has benefited from the problems suffered in other areas. In Peru, guerrilla warfare in recent years has dealt a heavy blow to the tourist industry and fear of street crime in Brazil has reduced the attraction of Rio de Janeiro as a dream destination for foreigners. More than 150,000 people are directly involved in Chile's tourist sector, an industry which earns the country more than U.S. $950 million each year. The state-run National Tourism Service, in partnership with a number of private companies, is currently running a world-wide campaign, taking part in trade fairs and international events to attract visitors to Chile. Chile's great strength as a tourist destination is its geographical diversity. From the parched Atacama Desert in the north to the Antarctic snowfields of the south, it is more than 5,000 km long. With the Pacific on one side and the Andean mountains on the other, Chile boasts natural attractions. Its beaches are not up to Caribbean standards but resorts such as Vina del Mar are generally clean and unspoilt and have a high standard of services. But the trump card is the Andes mountain range. There are a number of excellent ski resorts within one hour's drive of the capital, Santiago, and the national parks in the south are home to rare animals and plant species. The parks already attract specialist visitors, including mountaineers, who come to climb the technically difficult peaks, and fishermen, lured by the salmon and trout in the region's rivers. However, infrastructure development in these areas is limited. The ski resorts do not have as many lifts as their European counterparts and the poor quality of roads in the south means that only the most determined travelers see the best of the national parks. Air links between Chile and the rest of the world are, at present, relatively poor. While Chile's two largest airlines have extensive networks within South America, they operate only a small number of routes to the United States and Europe, while services to Asia are almost non-existent. Internal transport links are being improved and luxury hotels are being built in one of its national parks. Nor is development being restricted to the Andes. Easter Island and Chile's Antarctic Territory are also on the list of areas where the Government believes it can create tourist markets. But the rush to open hitherto inaccessible areas to mass tourism is not being welcomed by everyone. Indigenous and environmental groups, including Green peace, say that many parts of the Andes will suffer if they become over-developed. There is a genuine fear that areas of Chile will suffer the cultural destruction witnessed in Mexico and European resorts. The policy of opening up Antarctica to tourism is also politically sensitive. Chile already has permanent settlements on the ice and many people see the decision to allow tourists there as a political move, enhancing Santiago's territorial claim over part of Antarctica. The Chilean Government has promised to respect the environment as it seeks to bring tourism to these areas. But there are immense commercial pressures to exploit the country's tourism potential. The Government will have to monitor developments closely if it is genuinely concerned in creating a balanced, controlled industry and if the price of an increasingly lucrative tourist market is not going to mean the loss of many of Chile's natural riches.

单选题 Initial voyages into space introduced questions scientists had never before considered. Could an astronaut swallow food in zero gravity? To keep things simple, astronauts on the Project Mercury ate foods squeezed out of tubes. It was like serving them baby food in a toothpaste container. But these early tube meals were flavorless, and astronauts dropped too many pounds. "We know that astronauts have lost weight in every American and Russian manned flight," wrote NASA scientists Malcolm Smith in 1969. "We don't know why." Feeding people in space was not as easy as it looked. Floating around in space isn't as relaxing as it might sound. Astronauts expend a lot of energy and endure extreme stresses on their bodies. Their dietary requirements are therefore different from those of their gravity-bound counterparts on Earth. For example, they need extra calcium to compensate for bone loss. 'A low-salt diet helps slow the process, but there are no refrigerators in space, and salt is often used to help preserve foods," says Vickie Kloeris of NASA. "We have to be very careful of that." By the Apollo missions, NASA had developed a nutritionally balanced menu with a wide variety of options. Of course, all the items were freeze-dried or heat- treated to kill bacteria, and they didn't look like regular food. Today, the most elaborate outer-space meals are consumed in the International Space Station (ISS), where astronauts enjoy everything from steak to chocolate cake. The ISS is a joint venture between the U.S. and Russia, and diplomatic guidelines dictate the percentage of food an astronaut must eat from each country. NASA's food laboratory has 185 different menu items, Russia offers around 100, and when Japan sent up its first crew member in 2008, about 30 dishes came with him. Due to dietary restrictions and storage issues, astronauts still can't eat whatever they want whenever they feel like it. In 2008, NASA astronaut and ISS crew member Sandra Magnus became the first person to try to cook a meal in space. It took her over an hour to cook onions and garlic in the space station's food warmer, but she managed to create a truly delicious dish: grilled tuna (金枪鱼) in a lemon-garlic-ginger sauce---eaten from a bag, of course.

单选题 Economics has long been known as the dismal science. But is any economist so dreary as to criticize Christmas? At first glance, the holiday season in western economies seems a treat for those concerned with such vagaries as GDP growth. After all, everyone is spending; in America, retailers make 25% of their yearly sales and 60% of their profits between Thanksgiving and Christmas. Even so, economists find something to worry about in the nature of the purchases being made. Much of the holiday spending is on gifts for others. At the simplest level, giving gifts involves the giver thinking of something that the recipient would like—he tries to guess her preferences, as economists say—and then buying the gift and delivering it. Yet this guessing of preferences is no mean feat; indeed, it is often done badly. Every year, ties go unworn and books unread. And even if a gift is enjoyed, it may not be what the recipient would have bought had they spent the money themselves. Intrigued by this mismatch between wants and gifts, in 1993 Joel Waldfogel, then an economist at Yale University, sought to estimate the disparity in dollar terms. In a paper that has proved seminal in the literature on the issue, he asked students two questions at the end of a holiday season: first, estimate the total amount paid (by the givers) for all the holiday gifts you received; second, apart from the sentimental value of the items, if you did not have them, how much would you be willing to pay to get them? His results were gloomy: on average, a gift was valued by the recipient well below the price paid by the giver. The most conservative estimate put the average receiver's valuation at 90% of the buying price. The missing 10% is what economists call a deadweight loss: a waste of resources that could be averted without making anyone worse off. In other words, if the giver gave the cash value of the purchase instead of the gift itself, the recipient could then buy what she really wants, and be better off for no extra cost. If the results are generalized, a waste of one dollar in ten represents a huge aggregate loss to society. It suggests that in America, where givers spend $40 billion on Christmas gifts, $4 billion is being lost annually in the process of gift-giving. Add in birthdays, weddings and non-Christian occasions, and the figure would balloon. So should economists advocate an end to gift-giving, or at least press for money to become the gift of choice?

单选题 {{B}}Passage Two{{/B}} War may be a natural expression of biological instinct and drives toward aggression in the human species. Natural impulses of anger, hostility, and territoriality (守卫地盘的天性) are expressed through acts of violence. These are all qualities that humans share with animals. Aggression is a kind of innate (天生的) survival mechanism, an instinct for self-preservation, that allows animals to defend themselves from threats to their existence. But, on the other hand, human violence shows evidence of being a learned behavior. In the case of human aggression, violence cannot be simply reduced to an instinct. The many expressions of human violence are always conditioned by social conventions that give shape to aggressive behavior. In human societies violence has a social function: It is a strategy for creating or destroying forms of social order. Religious traditions have taken a leading role in directing the powers of violence. We will look at the ritual and ethical patterns within which human violence has been directed. The violence within a society is controlled through institutions of law. The more developed a legal system becomes, the more society takes responsibility for the discovery, control, and punishment of violent acts. In most tribal societies the only means to deal with an act of violence is revenge. Each family group may have the responsibility for personally carrying out judgment and punishment upon the person who committed the offense. But in legal systems, the responsibility for revenge becomes depersonalized and diffused. The society assumes the responsibility for protecting individuals from violence. In cases where they cannot be protected, the society is responsible for imposing punishment. In a state controlled legal system, individuals are removed from the cycle of revenge motivated by acts of violence, and the state assumes responsibility for their protection.The other side of a state legal apparatus is a state military apparatus while the one protects the individual from violence; the other sacrifices the individual to violence in the interests of the state. In war the state affirms supreme power over the individuals within its own borders. War is not simply a trial by combat to settle disputes between states; it is the moment when the state makes its most powerful demands upon its people for their commitment, allegiance, and supreme sacrifice. Times of war test a community's deepest religious and ethical commitments.
