单选题{{B}}Text 3{{/B}} Eating better and more adventurously is becoming an obsession, especially among people with money to spend. Healthier eating-and not-so-healthy eating-as well as the number and variety of food choices and venues continue to increase at an ever quickening pace. Globalization is the master trend that will drive the world of food in the years ahead. Consumers traveling the globe, both virtually and in reality, will be able to sweep up ingredients, packaged foods, recipes, and cooking techniques from every comer of the earth at an ever-intensifying and accelerating pace. Formerly remote ingredients and cooking styles are creating a whole new culinary mosaic as they are transplanted and reinterpreted all over the world. Many factors are behind this, but none more so than the influence of the great international hotel chains. Virtually every chef who has worked for Hilton, Westin, Peninsula, or any other major chain gathers global experience in locales as diverse as Singapore, New Orleans, Toronto, and Dubai. At each stop, they carry away cooking ideas and techniques they can and do use elsewhere. This trend will gain even greater momentum as ambitious young adults stake their own futures on internationalization, treating broader food away as an important aspect of their own advancement. Young people will need knowledge of food and ingredients from different continents and cultures as one aspect of socialization, enculturation, cultural exchange, and success. In country after country, there seems little doubt that global cuisine will make its biggest inroads among the younger set. Many in the generations now coming of age will treat world-ranging food knowledge and experience as key elements in furthering their personal plans, business acumen, and individual growth. The Internet has made global contacts a matter of routine. Computer networking will permit chefs and others in the food industry, including consumers, to link directly with the best available authorities in faraway nations, supplementing or bypassing secondhand sources of information altogether. Time, with all its implications, will also be a factor in emerging world food trends. More and more of us are destined to operate on global time-that is, at full tilt 24 hours a day. This will become the norm for companies with resources scattered all over the planet. Beyond the 24-hour supermarkets many of us already take for granted, there will also be three-shift shopping centers open at any hour. Restaurants in the great business capitals intent on cultivating an international clientele will serve midnight breakfasts or break-of-dawn dinners (with the appropriate wines) without raising a single eyebrow.

单选题 Animals on the Move A. It looked like a scene from 'Jaws' but without the dramatic music. A huge shark was lowly swimming through the water, its tail swinging back and forth like the pendulum of a clock. B. Suddenly sensitive nerve ending in the shark's skin picked up vibrations of a struggling fish. The shark was immediately transformed into a deadly, efficient machine of death. With muscles taut, the shark knifed through the water at a rapid speed. In a flash the shark caught its victim, a large fish, in its powerful jaws. Then, jerking its head back and forth, the shark tore huge chunks of flesh from its victim and swallowed them. Soon the action was over. Moving to Survive C. In pursuing its prey, the shark demonstrated in a dramatic way the important role of movement, or locomotion, in animals. D. Like the shark, most animals use movement to find food. They also use locomotion to escape enemies, find a mate, and explore new territories. The methods of locomotion include crawling, hopping, slithering, flying, swimming, or walking. E. Humans have the added advantage of using their various inventions to move about in just about any kind of environment. Automobiles, rockets, and submarines transport humans from deep oceans to as far away as the moon. However, for other animals movement came about naturally through millions of years of evolution. One of the most successful examples of animal locomotion is that of the shark. Its ability to quickly zero in on its prey has always impressed scientists. But it took a detailed study by Duke University marine biologists S. A. Wainwright, F. Vosburgh, and J. H. Hebrank to find out how the sharks did it. In their study the scientists observed sharks swimming in a tank at Marine land in Saint Augustine, Fla. Movies were taken of the sharks' movements and analyzed. Studies were also made of shark skin and muscle. Skin Is the Key F. The biologists discovered that the skin of the shark is the key to the animal's high efficiency in swimming through the water. The skin contains many fibers that crisscross like the inside of a belted radial tire. The fibers are called collagen fibers. These fibers can either store or release large amounts of energy depending on whether the fibers are relaxed or taut. When the fibers are stretched, energy is stored in them the way energy is stored in the string of a bow when pulled tight. When the energy is released, the fibers become relaxed. G. The Duke University biologists have found that the greatest stretching occurs where the shark bends its body while swimming. During the body's back and forth motion, fibers along the outside part of the bending body stretch greatly. Much potential energy is stored in the fibers. This energy is released when the shark's body snaps back the other way. H. As energy is alternately stored and released on both sides of the animal's body, the tail whips strongly back and forth. This whip-like action propels the animal through the water like a living bullet. Source of Energy I. What causes the fibers to store so much energy? In finding the answer the Duke University scientists learned that the shark's similarity to a belted radial tire doesn't stop with the skin. Just as a radial tire is inflated by pressure, so, too, is the area just under the shark's collagen 'radials'. Instead of air pressure, however, the pressure in the shark may be due to the force of the blood pressing on the collagen fibers. J. When the shark swims slowly, the pressure on the fibers is relatively low. The fibers are more relaxed, and the shark is able to bend its body at sharp angles. The animal swims this way when looking around for food or just swimming. However, when the shark detects an important food source, some fantastic involuntary changes take place. K. The pressure inside the animal may increase by l 0 times. This pressure change greatly stretches the fibers, enabling much energy to be stored. L. This energy is then transferred to the tail, and the shark is off. The rest of the story is predictable. Dolphin Has Speed Record M. Another fastmarine animal is the dolphin. This seagoing mammal has been clocked at speeds of 32 kilometers (20 miles) an hour. Biologists studying the dolphin have discovered that, like the shark, the animal's efficient locomotion can be traced to its skin. A dolphin's skin is made up in such a way that it offers very little resistance to the water flowing over it. Normally when a fish or other object moves slowly through the water, the water flows smoothly past the body. This smooth flow is known as laminar flow. However, at faster speeds the water becomes more turbulent along the moving fish. This turbulence muses friction and slows the fish down. N. In a dolphin the skin is so flexible that it bends and yields to the waviness of the water. O. The waves, in effect, become tucked into the skin's folds. This allows the rest of the water to move smoothly by in a laminar flow. Where other animals would be slowed by turbulent water at rapid speeds, the dolphin can race through the water at record breaking speeds. Other Animals Less Efficient P. Not all animals move as efficiently as sharks and dolphins. Perhaps the greatest loser in locomotion efficiency is the slug. The slug (鼻涕虫), which looks like a snail without a shell, lays down a slimy (黏滑的) trail over which it crawls. It uses so much energy producing the slimy mucus (黏液) and crawling over it that a mouse traveling the same distance uses only one twelfth as much energy. Q. Scientists say that because of the slug's inefficient use of energy, its lifestyle must be restricted. That is, the animals are forced to confine themselves to small areas for obtaining food and finding proper living conditions. Have humans ever been faced with this kind of problem?

单选题After a 300 million yuan renovation project, Lidai Diwang Miao, or the Imperial Temple of Emperors of Successive Dynasties, was reopened to the public last weekend. Originally constructed about 470 years ago, during the reign of Emperor Jiajing of the Ming Dynasty, the temple was used by emperors of both the Ming and Qing to offer sacrifices to their ancestors. It underwent two periods of renovation in the Qing Dynasty, during the reigns of emperors Yongzheng and Qianlong. From 1929 until early 2000, it was part of Beijing No. 159 Middle School. The temple's Jingdechongsheng Hall contains stone tablets memorializing 188 Chinese emperors. The Jinzhuan bricks used to pave the floor, the same as those used in the Forbidden City, are finely textured and golden-yellow in color. According to Xi Wei, an official from the Xicheng District government present at the reopening of the temple, Jinzhuan bricks were made in Yuyao, Suzhou, specially for imperial use. The renovation was done strictly according to that carried out at the orders of Emperor Qianlong, and only those sections of the temple too damaged to repair have been replaced.

单选题Another trend of the 1990s in the computer industry is toward multimedia formats, as the market for conventional types of computer--those that have computation and data processing as their major functions--has begun to become saturated. Multimedia computers are systems that can process graphics, sound, video, and animation in addition to traditional data processing. Videocassette recorders, televisions, telephones, and audiocassette players have recently undergone a change in technology from analog to digital formats. Television images, for example, can be processed by computer programs once they have been converted to digital signals, while those in conventional analog signals cannot. In other words, digital video images can be zoomed up or down, reshaped, or rearranged by the appropriate software. Also, due to advances in video-signal compression technology, the memory space required for storing a video program has been greatly reduced. Multimedia has important applications for consumer products and for business needs. Video scenes that are captured by camcorders can be combined with text, sound, and data and can be viewed on television sets in homes, schools, or offices. These multimedia presentations are becoming useful educational and commercial tools. For example, there are available encyclopaedias that contain video programs depicting animal behavior, geomorphic processing, and other natural phenomena. Automobile mechanics can watch videos that demonstrate how to repair new models. In business applications, documents can be annotated with 7oice or video. New consumer products can be more effectively marketed by demonstrating how they can be used. CD-ROMs of numerous other subjects have been recently published; all of them can be viewed on TV monitors using multimedia computers. These multimedia computer systems can, in turn, be incorporated into computer networks, enhancing the effectiveness of communication. This multitude of new products and capabilities has been made possible by the tremendous progress of microprocessor technology. Because of the advances in this area, personal computers have become more powerful, smaller, and less expensive, which has enabled computer networks to proliferate. Many of the tasks that were traditionally performed by mainframes have been transferred to personal computers connected to communications networks. Although the mainframe continues to be produced and serves a useful purpose, it has been used more often as one of many different computers and peripheral devices connected to computer networks. In this new role, the function of mainframes as powerful processors of database systems is becoming important, and, as a result, massively parallel computers with hundreds or thousands of microprocessors are being produced. In addition to being powerful, the microprocessors used for this purpose must be inexpensive, but low costs can be achieved only if they are mass-produced. Throughout the world, more than 100, 000, 000 personal computers and 500, 000 workstations are in use, whereas only several hundred supercomputers are in operation; the numbers of mainframes and minicomputers fall somewhere between those of supercomputers and workstations. Because of such high-volume production, microprocessors for personal computers or workstations tend to be inexpensive and are available for use in massively parallel computers as well.

单选题One of the important issues in the story is ______.

单选题 The fridge is considered a necessity. It has been so since the 1960s when packaged food first appeared with the label: 'store in the refrigerator.' In my fridgeless fifties childhood, I was fed well and healthily. The milkman came daily, the grocer, the butcher, the baker, and the ice-cream man delivered two or three times a week. The Sunday meat would last until Wednesday and surplus bread and milk became all kinds of cakes. Nothing was wasted, and we were never troubled by rotten food. Thirty years on food deliveries have ceased, flesh vegetables are almost unobtainable in the country. The invention of the fridge contributed comparatively little to the art of food preservation. A vast way of well-tried techniques already existed—natural cooling, drying, smoking, salting, sugaring, bottling... What refrigeration did promote was marketing—marketing hardware and electricity, marketing soft drinks, marketing dead bodies of animals around the globe in search of a good price. Consequently, most of the world's fridges are to be found, not in the tropics where they might prove useful, but in the wealthy countries with mild temperatures where they are climatically almost unnecessary. Every winter, millions of fridges hum away continuously, and at vast expense, busily maintaining an artificially-cooled space inside an artificially-heated house—while outside, nature provides the desired temperature free of charge. The fridge's effect upon the environment has been evident, while its contribution to human happiness has been insignificant, If you don't believe me, try it yourself, invest in a food cabinet and turn off your fridge next winter. You may miss the hamburgers, but at least you'll get rid of that terrible hum.

单选题 Five Problems Financial Reform Doesn't Fix A. The legislation concerning financial reform focuses on helping regulators detect and defuse (减少……的危险性) the next crisis. But it doesn't address many of the underlying conditions that can cause problems. B. The legislation gives regulators the power to oversee shadow banks and take failing firms apart, convenes a council of superregulators to watch the megafirms that pose a risk to the full financial system, and much else. C. But the bill does more to help regulators detect the next financial crisis than to actually stop it from happening. In that way, it's like the difference between improving public health and improving medicine: The bill focuses on helping the doctors who figure out when you're sick and how to get you better rather than on the conditions (sewer systems and air quality and hygiene standards and so on) that contribute to whether you get sick in the first place. D. That is to say, many of the weaknesses and imbalances that led to the financial crisis will survive our regulatory response, and it's important to keep that in mind. So here are five we still have to watch out for:1. The Global Glut (过于求) of Savings E. 'One of the leading indicators of a financial crisis is when you have a sustained surge in money flowing into the country which makes borrowing cheaper and easier,' says Harvard economist Kenneth Rogoff. Our crisis was no different: Between 1987 and 1999, our current account deficit—the measure of how much money is coming in versus going out—fluctuated between 1 and 2 percent of gross domestic product. By 2006, it had hit 6 percent. F. The sharp rise was driven by emerging economies with lots of growth and few investment opportunities—think China—funneling their money to developed economies with less growth and lots of investment opportunities. But we've gotten out of the crisis without fixing it. China is still growing fast, exporting faster, and sending the money over to US.2. Household Debt—and Why We Need It G. The fact that money is available to borrow doesn't explain why Americans borrowed so much of it. Household debt as a percentage of GDP went from a bit less than 60 percent at the beginning of the 1990s to a bit less than 100 percent in 2006. 'This is where I come to income inequality,' says Raghuram Rajah, an economist at the University of Chicago. 'A large part of the population saw relatively stagnant incomes over the 1980s and 1990s. Credit was so welcome because it kept people who were failing behind reasonably happy. You were keeping up, even if your income wasn't.' H. Incomes, of course, are even more stagnant now that unemployment is at 9 percent. And that pain isn't being shared equally: inequality has actually risen since before the recession, as joblessness is proving sticky among the poor, but recovery has been swift for the rich. Household borrowing is still more than 90 percent of GDP, and the conditions that drove it up there are, if anything, worse.3. The 'Shadow Banking' Market I. The financial crisis started out similarly severe, but it wasn't, at first, a crisis of consumers. It was a crisis of banks. It never became a crisis of consumers because consumer deposits are insured. But large investors—pension funds, banks, corporations, and others—aren't insured. But when they hear that their collateral (附属担保品) is dropping in value, they demand their money back. And when everyone does that at once, it's like an old-fashioned bank run: The banks can't pay everyone off at once, so they unload all their assets to get capital, the assets become worthless because everyone is trying to unload them, and the banks collapse. J. 'This is an inherent problem of privately created money,' says Gary Gorton, an economist at Princeton University. 'It is vulnerable to these kinds of runs.' This year, we're bringing this shadow banking system under the control of regulators and giving them all sorts of information on it and power over it, but we're not doing anything like deposit insurance, where we simply make the deposits safe so runs become an anachronism.4. Rich Banks K. In the 1980s, the financial sector's share of total corporate profits ranged from about 10 to 20 percent. By 2004, it was about 35 percent. Simon Johnson, an economist at MIT, recalls a conversation he had with a fund manager. 'The guy said to me, 'Simon, it's so little money! You can sway senators for $10 million!?'' Johnson laughs ruefully (后悔地) . 'These guys [big investors] don't even think in millions. They think in billions.' L. What you get for that money is favors. The last financial crisis fades from memory and the public begins to focus on other things. Then the finance guys begin nudging (旅说). They hold some fundraisers for politicians, make some friends, explain how the regulations they're under are onerous and unfair. And slowly, surely, those regulations come undone. This financial crisis will stick in our minds for a while, but not forever. And after briefly dropping to less than 15 percent of corporate profits, the financial sector has rebounded to more than 30 percent. They'll have plenty of money with which to help their friends forget this whole nasty affair.5. Lax (不严格的) Regulators M. The most troubling prospect is the chance that this bill, if we'd passed it in 2000, wouldn't even have prevented this financial crisis. That's not to undersell it: It would've given regulators more information with which to predict the crisis. But they had enough information, and they ignored it. They get caught up in boom times just like everyone else. A bubble, almost by definition, affects the regulators with the power to pop it. N. In 2005, with housing prices running far, far ahead of the historical trend, Bernanke said a housing bubble was 'a pretty unlikely possibility'. In 2007, he said Fed officials 'do not expect significant spillovers from the subprime market to the rest of the economy.' Alan Greenspan, looking back at the financial crisis, admitted in April that regulators 'have had a woeful record of chronic failure. History tells us they cannot identify the timing of a crisis, or anticipate exactly where it will be located or how large the losses and spillovers will be.'
