单选题Demand for the most common cosmetic surgery procedures, like breast enlargements and nose jobs, has increased by more than 400 per cent over the last decade. According to Dr. Dai Davies, of the Plastic Surgery Partnership in Hammersmith, the majority of cosmetic surgery patients are not chasing physical perfection. Rather, they are driven to fantastic lengths to improve their appearance by a desire to look normal. "What we all crave is to look normal, and normal is what is prescribed by the advertising media and other external pressures. They give us a perception of what is physically acceptable and we feel we must look like that." In America, the debate is no longer about whether surgery is normal; rather, it centres on what age people should be before going under the knife. New York surgeon Dr. Gerard Imber recommends "maintenance" work for people in their thirties. "The idea of waiting until one needs a heroic transformation is silly," he says. "By then, you"ve wasted 20 great years of your life and allowed things to get out of hand." Dr. Imber draws the line at operating on people who are under 18, however. "It seems that someone we don"t consider old enough to order a drink shouldn"t be considering plastic surgery." In the UK cosmetic surgery has long been seen as the exclusive domain of the very rich and famous. But the proportionate cost of treatment has fallen substantially, bringing all but the most advanced laser technology within the reach of most people. Dr. Davies, who claims to "cater for the average person", agrees. He says: "I treat a few of the rich and famous and an awful lot of secretaries. Of course, ￡3,000 for an operation is a lot of money. But it is also an investment for life which costs about half the price of a good family holiday." Dr. Davies suspects that the increasing sophistication of the fat injecting and removal techniques that allow patients to be treated with a local anaesthetic in an afternoon has also helped promote the popularity of cosmetic surgery. Yet, as one woman who recently paid ￡2,500 for liposuction to remove cellulite from her thighs admitted, the slope to becoming a cosmetic surgery veteran is a deceptively gentle one. "I had my legs done because they"d been bugging me for years. But going into the clinic was so low key and effective it whetted my appetite. Now I don"t think there"s any operation that I would rule out having if I could afford it."

单选题America acted quickly and decisively to the Great Recession, while Europeans seem paralyzed by the distant past. The swift and decisive U.S. response to the financial crisis and deep recession should be a model for other large developed economies. Yet Europe, which is now facing sovereign debt and banking problems and a slowdown in growth, seems reluctant to follow America's lead. The United States emerged from its 2008 economic cataclysm with relative speed because policymakers learned from history. Federal Reserve Chairman Ben Bernanke had famously internalized the charge that the central bank had contributed to the Great Depression. The frenzied response of the Bernanke Fed—guaranteeing all sorts of assets and markets, purchasing mortgage-backed securities, adopting a zero-interest rate policy, and expanding its balance shed to $ 2.3 trillion can be seen as signs of overcompensation. And from Japan's experience in the 1990s, the Fed learned the need for speed. While some critics have charged the U.S. fiscal stimulus was too small, the data suggest that the stimulus package has been a significant contributor to job retention and growth. Increased federal spending was needed in part to combat the declines in government spending by states. In the United States, the federal government helped prop up the states with injections of cash. In Europe, which lacks a powerful overarching federal government with the ability to tax and spend, fiscal policy is all bitter medicine and no spoonfuls of sugar. From the United Kingdom to the Czech Republic, and all points in between, governments are cutting spending and raising taxes. But these contractionary policies will retard economic growth, which will in turn lead to more problems for the banks. The European Central Bank and European governments are embracing fiscal austerity and comparative monetary tightness in these extraordinary times because they remain paralyzed by a terrible fear of inflation. The Federal Reserve has the dual mandate of controlling inflation and promoting employment. The ECB, by contrast, is concerned primarily with inflation. Never mind that the OECD data on inflation shows it is under control. The Europeans remain freaked out by the prospect of inflation at some point in the future. In its outlook, the OECD writes. "On inflation, the issue is not whether it is a risk today—it is not but whether it will be a risk in two years' time. " In the United States, the desire to avoid mistakes made in the distant and recent past has led to perhaps excessively vigorous fiscal and monetary policies. For Europeans, the desire to avoid mistakes made in the distant past has led to an excess of caution. When they look to history for guidance, European policymakers aren't looking at Washington in 2009, or Japan in the 1990s, or the United States in the 1930s. Rather, they look to Europe in the 1920s, a period when hyperinflation ravaged economies, disrupted the social order, destroyed social democracies, and led to the rise of Nazism.

单选题 In the 90's, people went crazy about wireless. Electronic communications once thought bound permanently to the world of cables and hard-wired connections suddenly were sprung free, and the possibilities seemed endless. Entrenched monopolies would fall, and a new uncabled era would usher in a level of intimate contact that would not only transform business but change human behavior. Such was the view by the end of that groundbreaking decade-the 1890s. To be sure, the wild publicity of those days wasn't all hot air. Marconi's "magic box" and its contemporaneous inventions kicked off an era of profound changes, not the least of which was the advent of broadcasting. So it does seem strange that a century later, the debate once more is about how wireless will change everything. And once again, the noisy confusion is justified. Changes are on the way that are arguably as earth shattering as the world's first wireless transformation. Certainly a huge part of this revolution comes from introducing the most powerful communication tools of our time. Between our mobile phones, our BlackBerries and Treos, and our Wi-Fi (Wireless Fidelity) computers, we're always on and always connected-and soon our cars and our appliances will be, too. While there has been considerable planning for how people will use these tools and how they'll pay for them, the wonderful reality is that, as with the Internet, much of the action in the wireless world will ultimately emerge from the imaginative twists and turns that are possible when digital technology trumps the analog mindset of telecom companies and government regulators. Wi-Fi is itself a shining example of how wireless innovation can shed the tethers of conventional wisdom. At one point, it was assumed that when people wanted to use wireless devices for things other than conversation, they'd have to rely on the painstakingly drawn, investment-heavy standards adopted by the giant corporations that earn a lot through your monthly phone bill. But then some researchers came up with a new communications standard exploiting an unlicensed part of the spectrum. It was called 802.11, and only later sexed up with the name Wi-Fi. Though the range of signal was only some dozens of meters, Wi-Fi turned out to be a great way to wirelessly extend an Internet connection in the home or office. A new class of activist was born: the bandwidth liberator, with a goal of extending free wireless internet to anyone venturing within the range of a free hotspot. Meanwhile, Apple Computer seized on the idea as a consumer solution, others followed and now Wi-Fi is as common as the modem once was.

单选题Recalculating the global use of phosphorus, an important fertilizer element of modem agriculture, a team of researchers warns that the world's stocks may soon be in short supply and that overuse in the industrialized world has become a leading cause of the pollution of lakes, rivers and streams. Writing in the Feb. 14 edition of the journal Environmental Research Letters, Stephen Carpenter of the University of Wisconsin-Madison and Elena Bennett of McGill University report that the human use of phosphorus, primarily in the industrialized world, is causing the widespread eutrophication of fresh surface water. What's more, the minable global stocks of phosphorus are concentrated in just a few countries and are in decline, posing the risk of global shortages within the next 20 years. "There is a finite amount of phosphorus in the world," says Carpenter, one of the world's leading authorities on lakes and streams. "This is a material that's becoming rarer and we need to use it more efficiently." Phosphorus is an essential element for life. Living organisms, including humans, have small amounts and the element is crucial for driving the energetic processes of cells. In agriculture, phosphorus mined from ancient marine deposits is widely used to boost crop yields. The element also has other industrial uses. But excess phosphorus from fertilizer that washes from farm fields and suburban lawns into lakes and streams is the primary cause of the algae blooms that destroy freshwater ecosystems arid degrade water quality. Phosphorus pollution poses a risk to fish and other water life as well as to the animals and humans who depend on clean fresh water. In some instances, excess phosphorus sparks blooms of toxic algae, which pose a direct threat to human and animal life. "If you have too much phosphorus, you get eutrophication," explains Carpenter, of the cycle of excessive plant and algae growth that significantly degrades bodies of fresh water. "Phosphorus stimulates the growth of algae and weeds near shore and some of the algae can contain cyanobacteria, which are toxic. You lose fish. You lose water quality for drinking." The fertilizer-fueled algae blooms themselves amplify the problem as the algae die and release accumulated phosphorus back into the water. Complicating the problem, says Carpenter, is the fact that excess phosphorus in the environment is a problem primarily in the industrialized world, mainly Europe, North America and parts of Asia. In other parts of the world, notably Africa and Australia, soils are phosphorus poor, creating a stark imbalance. Ironically, soils in places like North America, where fertilizers with phosphorus are most commonly applied, are already loaded with the element. Bennett and Carpenter argue that agriculture practices to better conserve phosphate within agricultural ecosystems are necessary to avert the widespread pollution of surface waters. Phosphorus from parts of the world where the element is abundant, they say, can be moved to phosphorus deficient regions of the world by extracting phosphorus from manure, for example, using manure digesters.
