单选题 Three makes a trend. The Washington Post Co. Friday announced that it would look to sell its iconic headquarters building in downtown Washington, D.C. In January, the Detroit Free Press and The Detroit News announced they would put up for sale their headquarters. The same month, Frank Gannett said it will sell the building that houses the Rochester, N.Y., Democrat circulation revenues are back to where they were in 1996. The digital numbers are rising, but not nearly fast enough. Print media is hampered by high fixed costs incurred in the pre-digital era-pensions and union contracts, equipment like printing presses, large numbers of employees, and big office buildings. Virtually every newspaper company has engaged in drastic measures—laying off experienced employees, eliminating sections, cutting back printing from daily to a few days per week. Those efforts are all meant to lower day-to-day operating costs. But we've also seen newspaper companies seek onetime injections of cash by selling off non-core assets. Increasingly, the headquarters building—typically located right in the middle of town-is falling into the non-core asset category. Traditionalists may find these sales and the continued shrinking of newspapers' real-estate footprints to be depressing. But it's actually a positive development. Call it creative destruction, or adaptive reuse. In cities around the country, investors are finding better uses for properties. In lower Manhattan, Class B office buildings that used to house financial firms have been converted into ex pensive condos. "It's a great thing, because it drives more tax revenue to the cities. And it gives the suburbs a run for the money," said Jonathan Miller, president of appraisal company MillerSamuel. In D.C., the Washington Post will likely fetch an excellent price for its headquarters because Washington is a boomtown. Throughout D.C., investors are plowing cash into housing, office, and retail developments. The building that housed the organization that exposed the Watergate scandal may become the next Watergate complex. Of course, progress inevitably displaces the prior tenants. It's likely the new homes that will be occupied by newspapermen and newspaperwomen in Washington, Rochester, and Detroit will be less grand, less central, and less historic than their current homes. And the sale of these properties alone won't solve the newspapers' financial problems. But it will buy them a very valuable commodity: time.

单选题Text 4 Non-indigenous (non-native) species of plants and animals arrive by way of two general types of pathways. First, species having origins outside the United States may enter the country and become established either as free-living populations or under human cultivation--for example, in agriculture, horticulture, aquaculture, or as pets. Some cultivated species subsequently escape or are released and also become established as free-living populations. Second, species of either U.S. or foreign origin and already within the United States may spread to new locales. Pathways of both types include intentional as well as unintentional species transfers. Rates of species movement driven by human transformations of natural environments as well as by human mobility--through commerce, tourism, and travel--greatly exceed natural rates by comparison. While geographic distributions of species naturally expand or contract over historical time intervals (tens to hundreds of years), species' ranges rarely expand thousands of miles or across physical barriers such as oceans or mountains. Habitat modification can create conditions favorable to the establishment of non-indigenous species. Soil disturbed in construction and agriculture is open for colonization by non-indigenous weeds, which in turn may provide habitats for the non-indigenous insects that evolved with them. Human-generated changes in fire frequency, grazing intensity, as well as soil stability and nutrient levels similarly facilitate the spread and establishment of non-indigenous plants. When human changes to natural environments span large geographical areas, they effectively create passages for species movement between previously isolated locales. The rapid spread of the Russian wheat aphid to fifteen states in just two years following its 1986 arrival has been attributed in part to the prevalence of alternative host plants that are available when wheat is not. Many of these are non-indigenous grasses recommended for planting on the forty million or more acres enrolled in the U.S. Department of Agriculture Conservation Reserve Program. A number of factors perplex quantitative evaluation of the relative importance of various entry pathways. Time lags often occur between establishment of non-indigenous species and their detection, and tracing the pathway for a long-established species is difficult. Experts estimate that non-indigenous weeds are usually detected only after having been in the country for thirty years or having spread to at least ten thousand acres. In addition, federal port inspection, although a major source of information on non-indigenous species pathways, especially for agriculture pests, provides data only when such species enter via closely-examined routes. Finally, some comparisons between pathways defy quantitative analysis--for example, which is more "important": the entry path of one very harmful species or one by which many but less harmful species enter the country?

The father, Leopold, was a master of music in Austria. His mother was warm-hearted. There were two children, Marianne, a schoolgirl, and little Wolfgang, a child not quite four years old. Marianne was learning to play the piano, and day after day Leopold stood behind her as she practiced. How patient their father was, and how cleverly he showed Marianne how to play some particularly difficult pieces! She was making progress, very good progress, and that was excellent. And there, almost lost in the big chair, sat Wolfgang, who never had to be told to keep quiet when looking over Marianne's shoulder. At that moment Wolfgang climbed on his father's knees and begged to be allowed to play the pretty piece Marianne had now mastered. What a joke that was! Picking up his baby son, Leopold laughed and said, "Look at your hands. You must wait, little man!" There was no end to the fun during tea, and Marianne had to tell her mother about Wolfgang wanting to play a difficult piece. When the meal was finished, Marianne helped to clear away the dishes. Suddenly Leopold got up. "Listen!" said he in a surprised voice. "Listen! Marianne is playing the piece better than ever!" But Marianne was washing dishes in the kitchen. His wife following, Leopold walked quietly upstairs, the lamp in one hand, his music book in the other. He pushed open the door, and there was little Wolfgang playing in the darkness. "I love it" whispered the child. It was the beginning of Mozart's life of music.

单选题Jazz is a kind of music that has often been called the only art form to originate in the United States. The history of 31 began in the late 1800s. The music grew from a 32 of influences, including black American music, African rhythms, American band traditions and instruments, and European harmonies and forms. Much of the best jazz is still written and 33 in the United States. But musicians from many other countries are 34 major contributions to jazz. Jazz was actually 35 appreciated as an important art form in Europe 36 it gained such recognition in the United States. The earliest jazz was performed by black Americans who had little or no training in Western music. These musicians drew on a strong musical culture from 37 life. As jazz grew 38 popularity, its sound was influenced by 39 with formal training and classical backgrounds. During its history, jazz has absorbed influences from the folk and classical music of Africa, and other parts of the world. The development of instruments with new and 40 characteristics has also influenced the Sound of jazz.

单选题The New Generation Since his first appearance 13 years ago, Harry Potter Has loomed over a generation. In 1997, he was 11 years old—and so were legions of his devotees. The boy wizard, whose final adventures hit the screen next week in Harry Potter and the Deathly Hallows: Part 1, is still a teenager, but is there a sense in which his fans, now 24, are also finding it hard to grow up? With many young adults still living at home or remaining in education, sociologists have argued that the age of maturity is changing fast; that the current crop of twentysomethings is stuck. Any attempt to define a generation will fail. But how much do we know about the people who made Harry Potter a superstar? Are they the iiber-confident, sex-savvy go-getters of advertising fantasy, or a cuckoo generation destined to remain in the family nest, devoid of career prospects or financial stability, sold out by the grownups who frittered away their future? We can surely take it for granted that this group of people are more technologically literate and enthusiastic than any that has preceded them; recent data from the Office for National Statistics suggests that only 1 per cent of 16-to 24-year-olds has never accessed the Internet. But it"s also common sense to assume that, while young people might revel in how easy it is to communicate with one another, they are likely to feel less confident in the current economic climate about their ability to access and afford education, to enter the job market, to get a foothold on the property ladder and to rely on the State to provide a safety net in times of trouble. In short, young people are both more connected and more alone than ever. On one side they are awash in a sea of celebrity culture, in which young people such as Wayne Rooney can be materially rewarded beyond anybody"s wildest dreams for the possession of a single skill, and the less gifted are briefly lauded on a television talent show before a long descent into obscurity. On the other, economic, environmental and geopolitical convulsions creajte a sense of collective catastrophe that seems to deflate the very idea of individual aspiration. So how does that make them feel? Mel Smith, who works for the Youth Support Service as part of the Transition to Adulthood(T2 A)Alliance, which was established to provide support for young adults in the criminal justice system, explains how some of the people she works with find that their age makes them even more vulnerable. " It"s a very difficult time, the very early twenties, because of the way that a lot of the support is set up, " she says. " As they reach age milestones, they move from youth to adult services; they may find themselves moved to a different service just because they"ve had a birthday. " When Thomas Viney, a 27-year-old graduate living in London, read a lengthy article in The New York Times arguing that the delayed adulthood experienced by many twentysomethings constituted a new developmental life stage, he felt the need to respond. He wrote that by the time his parents were his age, they had established a household, had children, got proper jobs, started savings schemes and pension plans and, more generally, had learnt to look after themselves. By contrast, he had amassed little of any tangible value and his life, punctuated by amusing but random interactions with his mates, seemed more defined by aimlessness than purpose. When a girlfriend said she thought she was pregnant(she wasn"t), the cold wave of responsibility was enough to sweep him completely off his feet. Viney believes that his experience is not simply a typical twentysomething scenario but indicative of a far more damaging malaise. "A lot of people in my generation, " he tells me, "were brought up to think that they were very special and that they had something to contribute to the world—not through hard work, but through the arts. I think we"re lost; that we no longer think it"s OK to knuckle down and apply ourselves, because that isn"t the life that we were promised. " His upbringing was middle class, rather than wealthy, but he feels that it took place against the backdrop of what he calls a time of "biblical" plenty and abundance. He also says that his generation has been "encouraged to enjoy ourselves" , that there"s something wrong with you if you don"t and that there will be few consequences to a life of hedonism. As a result, he and his friends, with a couple of exceptions, have barely a serious job or stable domestic environment among them. Viney himself, though, is taking a few tentative steps towards serious adulthood, working in publishing and writing in his spare time. What he has learnt, he says, is that for all that his parents had to sacrifice, they gained far more than they lost. Facebook, as everyone but a Martian knows, was founded by a bunch of precocious youths. Apart from all the online games, groups, jokes and pokes, probably the most recognisable feature of Facebook is the "status update". But what might the status update of this disparate bunch be? How would they encapsulate all the exuberance, anxiety, yearning and joyfulness that being twentysomething brings? Perhaps something like: "Status pending. Update to follow. Don"t wait up. "

单选题It was the biggest scientific grudge match since the space race. The Genome Wars had everything: two groups with appealing leaders ready to fight in a scientific dead heat, pushing the limits of technology and rhetoric as they battled to become the first to read every last one of the 3 billion DNA "letters" in the human body. The scientific importance of the work is unquestionable. The completed DNA sequence is expected to give scientists unprecedented insights into the workings of the human body, revolutionizing medicine and biology. But the race itself, between the government's Human Genome Project and Rockville, Md., biotechnology company Celera Genomics, was at least partly symbolic, the public/private conflict played out in a genetic lab. Now the race is over. After years of public attacks and several failed attempts at reconciliation, the two sides are taking a step toward a period of calm. HOP head Francis Collins (and .Ari Patrinos of the Department of Energy, an important ally on the government side) and Craig Venter, the founder of Celera, agreed to hold a joint press conference in Washington this Monday to declare that the race was over (sort of), that both sides had won (kind of) and that the hostilities were resolved (for the time being). No one is exactly sure how things will be different now. Neither side will be turning off its sequencing machines any time soon--the "finish lines" each has crossed are largely arbitrary points, "first drafts" rather than the definitive version. And while the joint announcement brings the former Genome Warriors closer together than they've been in years, insiders say I that future agreements are more likely to take the form of coordination, rather than outright collaboration. The conflict blew up this February when Britain's Welcome Trust, an HGP participant, released a confidential letter to Celera outlining the HGP's complaints. Venter called the move "a lowlife thing to do," but by spring, there were the first signs of a thaw. "The attacks and nastiness are bad for science and our investors," Venter told Newsweek in March, "and fighting back is probably not helpful." At a cancer meeting earlier this month, Venter and Collins praised each other's approaches, and expressed hope that all of the scientists involved in sequencing the human genome would be able to share the credit By late last week, that hope was becoming a reality as details for Monday's joint announcement were hammered out. Scientists in both camps welcomed an end to the hostilities. "If this ends the horse race, science wins." With their difference behind them, or at least set aside, the scientists should now be able to get down to the interesting stuff, figuring how to make use of all that data.
