单选题The Lower East Side Tenement Museum is one of the smaller museums in New York. It lets visitors experience how early immigrants to the United States lived. The museum is a building at Ninety-Seven Orchard Street. It was built in eighteen sixty-three by a German immigrant named Lucas Glockner. He worked as a tailor making clothes before investing his money to develop a property. His tenement building was one of many built in New York as a way to profit from the increasing demand for housing for immigrants. The word "tenement" comes from a Latin word meaning "to hold." A tenement building holds many rooms where different families lived. The word is not used much anymore in the United States. When people use the word today, they mean an old crowded building where poor families live in terrible, unhealthy conditions. But in the eighteen hundreds, the word "tenement" simply meant a building in which many families lived. Later, many immigrant families improved their living conditions by moving from the Lower East Side to other areas of New York. Some lived in the same kinds of buildings, but the living areas were cleaner and larger. They did not want to call them tenements, so they called them apartment buildings instead. Over the years, New York City officials passed laws to improve conditions in the tenements. The owners of Ninety-Seven Orchard Street placed gas lighting in the building in the eighteen nineties. They added water and indoor toilets in nineteen-oh-five, and electric power in nineteen twenty-four. Then they refused to make any more improvements. They closed the building in nineteen thirty-five. In nineteen ninety-eight, the federal government declared the building a protected National Historic Place. Workers at the Tenement Museum researched the history of the building and its twenty apartments. They found more than two thousand objects that belonged to people who lived there. They also learned the histories of many of the seven thousand people from more than twenty countries who lived there. And they spoke with and recorded memories of people who lived at Ninety-Seven Orchard Street as children. Museum officials used this information to recreate some of the apartments as they would have looked during different time periods in the building"s history. These apartments are what people see when they visit the Lower East Side Tenement Museum.

单选题New technology links the world as never before. Our planet has shrunk. It's now a "global village" where countries are only seconds away by fax or phone or satellite link. And, of course, our ability to benefit from this high-tech communications equipment is greatly enhanced by foreign language skills. Deeply involved with this new technology is a breed of modern businesspeople who have a growing respect for the economic value of doing business abroad. In modern markets, success overseas often helps support domestic business efforts. Overseas assignments are becoming increasingly important to advancement within executive ranks. The executive stationed in another country no longer need fear being "out of sight and out of mind. " He or she can be sure that the overseas effort is central to the company's plan for success, and that promotions often follow or accompany an assignment abroad. If an employee can succeed in a difficult assignment overseas, superiors will have greater confidence in his or her ability to cope back in the United States where cross-cultural considerations and foreign language issues are becoming more and prevalent (普遍的). Thanks to a variety of relatively inexpensive communications devices with business applications, even small businesses in the United States are able to get into international markets. English is still the international language of business. But there is an eve-ggrowing need for people who can speak another language. A second language isn't generally required to get a job in business, but having language skills gives a candidate the edge when other qualifications appear to be equal. The employee posted abroad who speaks the country's principal language has an opportunity to fast forward certain negotiations, and can have the cultural insight to know when it is better to move more slowly. The employee at the home office who can communicate well with foreign clients over the telephone or by fax machine is an obvious asset to the firm.

单选题The Vikings have left many traces of their settlement which are still visible today. Archaeology provides physical evidence of their conquests, settlement and daily life. The study of place names and language shows the lasting effect which the Viking settlements had in the British Isles, and DNA analysis provides some insights into the effect the Vikings had on the genetic stock of the countries where they settled. All of this provides valuable information, but the only reason that we have an idea of the "Vikings" as a people is their appearance in the written sources. Unfortunately, the value of the written evidence is limited. Not a lot of evidence survives, and much of what we have is either uninformative or unreliable. Many popular ideas about Vikings are nineteenth-century inventions. Others are the result of early historians accepting sources which modern scholars now regard as completely unreliable. In Scandinavia the Viking Age is regarded as part of prehistory because there are practically no contemporary written sources. Even in western Europe, the Viking Age is often seen as part of the "Dark Ages", from which comparatively few historical records have survived. Surviving accounts of Viking activity were almost exclusively written by clergymen (神职人员). These monastic chronicles (编年史) outline broadly what happened, at what date. There are also sources of a more directly religious nature, such as the much-quoted letters of Alcuin, and Wulfstan's famous "Sermon of the Wolf ", both of which chose to interpret the Viking raids as God's punishment on the Anglo-Saxons for their sins. Even the chronicles reflect the fact that the Vikings often attacked monasteries for their wealth, which created an obvious bias against them, and the hostile tone of these contemporary accounts has done much to create the popular image of Viking atrocities. However, modern historians have noted that the same sources show Christian rulers behaving equally unpleasantly, but without being condemned on religious grounds. We tend to think of the Vikings as a race of Scandinavian warriors, but the reality is more complex. Raids on the British Isles and the coasts of France and Spain were the work of Vikings from Norway and Denmark. The word Viking means one who lurks in a "vik" or bay, in effect, a pirate. The word "Viking" has come to describe a whole new age in Europe between about 800 and 1150. This is despite the fact that Vikings were not just pirates and warriors but also traders and colonists. But at the start of the Viking Age in the last decade of the 8th century, loot and adventure were the main goals of the Norwegians who raided in Scotland and Ireland and of the Danes who attacked England. Gold and silver treasures accumulated by the great monasteries could be converted into personal wealth and thus power, and captives could be sold as slaves. What better way for the young sons of good families to earn their way and see the world?

单选题Ten years ago, when environmental lawyer Kassie Siegel went in search of an animal to save the world, the polar bear wasn't at all an obvious choice. Siegel and Brendan Cummings of the Center for Biological Diversity in Joshua Tree, Calif. , were looking for a species whose habitat was disappearing due to climate change, which could serve as a symbol of the dangers of global warming. Her first candidate met the scientific criteria—it lived in ice caves in Alaska's Glacier Bay, which were melting away—but unfortunately it was a spider. You can't sell a lot of T shirts with pictures of an animal most people would happily step on. Next, Siegel turned to the Kittlitz's murrelet, a small Arctic seabird whose nesting sites in glaciers were disappearing. In 2001, she petitioned the Department of the Interior to add it to the Endangered Species list, but Interior Secretary Gale Norton turned her down. Elkhorn and staghorn coral, which are threatened by rising water temperatures in the Caribbean, did make it onto the list, but as iconic species they fell short insofar as many people don't realize they're alive in the first place. The polar bear, by contrast, is vehemently alive and carries the undeniable charisma of a top predator. And its dependence on ice was intuitively obvious; it lives on it most of the year. But it took until 2004 for researchers to demonstrate that shrinking sea ice was a serious threat to the bears' population. On Feb. 16, 2005—the day the Kyoto Protocol to curb greenhouse-gas emissions took effect, without the participation of the United States—Siegel petitioned to list polar bears as endangered. Three years later her efforts met with equivocal (不明确的) success, as Interior Secretary Dirk Kempthorne designated the bears as "threatened" (not endangered), a significant concession from an administration that has stood almost alone in the world in its reluctance to acknowledge the dangers of climate change. The Endangered Species Act (ESA) , whose odd lists of snails and bladderworts sometimes seemed stuck in the age of Darwin, had been thrust into the mainstream of 21st-century environmental politics. Break out the T shirts!

单选题{{B}}Passage Five{{/B}} By 2010, half the recoverable material in Britain's dustbins will be recycled—that, at least, was the target set by Chris Patten, Secretary of State for the Environment. But he gave no clues as to how Britain should go about achieving it. While recycling enthusiasts debate the relative merits of different collection systems, it will largely be new technology, and the opening up of new markets, that makes Patten's target attainable: a recycling scheme is successful only if manufacturers use the recovered materials in new products that people want to buy. The first question is how best to separate clean element—glass containers, plastics, and some paper and metal containers that is relatively clean when discarded—from mixed refuse. This clean element is the main target for Britain's recyclers. The method of collection is important because manufacturers will not reuse collected material unless it is clean and available in sufficient quantities. A bewildering assortment of different collection schemes operates in the rest of Europe, and pilot schemes are now under way in many British cities. A realistic target for recycling mixed refuse is somewhere between 15 and 25 percent by weight, according to researchers at the Department of Trade and Industry's Laboratory. Statistics compiled by researchers at the University of East Anglia show that Britain could almost halve the total weight of domestic waste going to landfill by a combination of "collect” schemes(such as doorstep collections for newspapers),"bring” schemes(such as bottle banks)and plants for extracting metals. This estimate makes two important assumptions. One is that the government will bring in legislation to encourage the creation, of markets for products made from recycled materials, especially glass, paper and plastics. The other is that industry will continue to introduce new technology that will improve both the products and the techniques used to separate recoverable materials from mixed refuse.
