单选题 In recent years, Israeli consumers have grown more demanding as they've become wealthier and more worldly-wise. Foreign travel is a national passion; this summer alone, one in 10 citizens will go abroad. Exposed to higher standards of service elsewhere, Israelis are returning home expecting the same. American firms have also begun arriving in large numbers. Chains such as KFC, McDonald's and Pizza Hut are setting a new standard of customer service, using strict employee training and constant monitoring to ensure the friendliness of frontline staff. Even the American habit of telling departing customers to "Have a nice day" has caught on all over Israel. "Nobody wakes up in the morning and says, ' Let's be nicer' "says Itsik Cohen, director of a consulting firm. "Nothing happens without competition." Privatization, or the threat of it, is a motivation as well. Monopolies (垄断者) that until recently have been free to take their customers for granted now fear what Michael Perry, a marketing professor, calls "the revengeful (报复的) consumer". When the government opened up competition with Bezaq, the phone company, its international branch lost 40% of its market share, even while offering competitive rates. Says Perry, " People wanted revenge for ali the years of bad service." The electric company, whose monopoly may be short-lived, has suddenly stopped requiring users to wait haft a day for a repairman. Now, appointments are scheduled to the half-hour. The graceless EIAI Airlines, which is already at auction (拍卖), has retrained its employees to emphasize service and is boasting about the results in an ad campaign with the slogan, "You can feel the change in the air. "For the first time, praise outnumbers complaints on customer survey sheets.

单选题In the last century people have accomplished almost unbelievable technological feats. From the invention of the steamship to the development of the spaceship, humankind"s mechanical genius has been displayed. A phone is picked up and through a thin, plastic-coated wire, conversation reaches people around the block or thousands of miles away. Television creates images on a glass screen, and soon, through holography(全息照相技术) a screen may not even be needed. This apparent technological mastery has led people to the quite incorrect and dangerous belief that technology can solve any and every problem the environment presents. All that is needed is enough time, effort, money, and know-how. But not everything is possible. For instance, unaided humans in their present form could not run a mile in one minute, or anywhere near it. That is believed to be biologically impossible. Just as some things are biologically impossible, others are technologically infeasible or improbable. It is not likely that we will solve the world"s food problem technologically. Even with the great advances in methods of food production, more people are starving today than ever before. This is partially because population is increasing faster than the research and innovations that compensate for such population growth. Technology, for most people, is not the solution to the loneliness or despair, nor will it alleviate(缓解) hatred or prejudice. It can be a tool but not a total cure. In fact, the advanced technologies of modern people might ultimately end our existence, because if technological "progress" is not accompanied by appropriate social change and ecological(生态的) responsibility, people may drown in the poisons of their own industrial wastes.

单选题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, is having 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 USA 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 US $ 950 million each year. The state-run National Tourism Service, in partnership with a number of private companies, is currently running a worldwide 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 5,000km 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 tromp 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 animal 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, infrastructural development in these areas is limited. The ski resorts do not have as many lifts and pistes 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 Greenpeace, 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{{B}}Passage Four{{/B}} For some time past it has been widely accepted that babies and other creatures learn to de things because certain acts lead to "rewards"; and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological "drives" as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise. It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome. Papousek began his studies by using milk in the normal way to "reward" the babies and so teach them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children's responses in situations where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement "switched on" a display of lights-and indeed that they were capable of learning quite complex turns to bring about this result. For instance, two left or two right, or even to make as many as three turns to one side. Papousek's light display was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the lights closely although they would "smile and bubble" when the display came on. Papousek concluded that it was not primarily the sight of the lights which pleased them, it was the success they were achieving in solving the problem, in mastering the skill, and that there exists a fundamental human urge to make sense of the world and bring it under intentional control.

单选题With a series of well-timed deals, private-equity firms are giving traditional mediamanagers cause to be envious, The Warner Music transaction, in which Edgar Bronfman junior and three private-equity firms paid Time Warner $ 2.6 billion for the unit in 2003, is already judged a financial triumph for the buyers. Their success is likely to draw still more private-equity into the industry. And the investments are likely to get bigger: individual privateequity funds are growing—a $10 billion fund is likely this year—so even the biggest media firms could come within range, especially ff private-equity investors club together, Some private-equity firms have long put money in media assets, but mostly reliable, relatively obscure businesses with stable cash flows. Now, some of them are placing big strategic bets on the more volatile bits, such as music and movies. And they are currently far more confident than the media old guard that the advertising cycle is about to turn sharply upwards. One reason why private-equity is making its presence felt in media is that it has a lot of money to invest. Other industries are feeling its weight too. But private-equity's buying spree (狂购乱买) reveals a lot about the media business in particular. Media conglomerates (联合公司) lack the confidence to make big acquisitions, after the last wave of deals went wrong. Executives at Time Warner, for instance, which disastrously merged with AOL in 2000, wanted to buy MGM, a movie studio, but the board (it is said) were too nervous. Instead, private-equity firms combined with Sony, a consumer-electronics giant, to buy MGM late last year. Private-equity's interest also reflects the fact that revenue growth in media businesses such as broadcast TV and radio is now hard to come by. The average annual growth rate for 12 categories of established American media businesses in 1998-2003, excluding the internet, was just 3.4% , says Veronis Suhler Stevenson, an investment bank. Private-equity puts a higher value on low-growth, high cashflow assets than the public stockmarket, says Jonathan Nelson, founder of Providence Equity Partners, a media-focused private-equity firm. What private-equity men now bring to the media business, they like to think, is financial discipline plus an enthusiastic attitude towards new technology. Old-style media managers, claim the newcomers, are still in denial about how technology is transforming their industry. Traditional media managers grudgingly agree that, so far, private-equity investors are doing very nicely indeed from their entertainment deals. The buyers of Warner Music have already got back most of their $ 2.6 billion from the farm by cutting costs, issuing debt and making special payouts to shareholders. This year, its investors are expected to launch an initial public offering, which could bring them hundreds of millions more.
