单选题{{B}}Text 2{{/B}} Joseph Rykwert entered his field when post-war modernist architecture was coming under fire for its alienating embodiment of outmoded social ideals. Think of the UN building in New York. the city of Brasilia. the UNESCO building in Paris, the blocks of housing "projects" throughout the world. These tall. uniform boxes are set back from the street, isolated by windswept plazas. They look inward to their own functions, presenting no "face" to the inhabitants of the city, no "place" for social interaction. For Mr. Rykwert. who rejects the functionalist spirit of the Athens Charter of 1933. a manifesto for much post-war building, such facelessness destroys the human meaning of the city. Architectural form should not rigidly follow function, but ought to reflect the needs of the social body it represents. Like other forms of representation, architecture is the embodiment of the decisions that go into its making, not the result of impersonal forces, market or history. Therefore. says Mr. Rykwert, adapting Joseph de Maistre's dictum that a nation has the government it deserves, our cities have the faces they deserve. In this book. Mr. Rykwert. a noted urban historian of anthropological love, offers a flaneur's approach to the city's exterior surface rather than an urban history from the conceptual inside out. He does not drive, so his interaction with the city affords him a warts-and-all view with a sensual grasp of what it is to be a "place". His story of urbanization begins, not surprisingly, with the industrial revolution when populations shifted and increased, exacerbating problems of housing and crime. In the 19th century many planning programs and utopias (Ebenezer Howard's garden city and Charles Fourier's "phalansteries" among them) were proposed as remedies. These have left their mark on 20th-century cities, as did Baron Hausmann's boulevards in Paris, Eugene Viollet-le-Duc's and Owen Jones's arguments for historical style, and Adolf Loos's fateful turn-of-the-century call to abolish ornament which, in turn, inspired Le Corbusier's bare functionalism. The reader will recognize all these ideas in the surfaces of the cities that hosted them: New York. Paris. London, and Vienna. Cities changed again after the Second World War as populations grew. technology raced and prosperity spread. Like it or not, today's cities are the muddled product, among other things, of speed. greed, outmoded social agendas and ill-suited postmodern aesthetics. Some lament the old city's death; others welcome its replacement by the electronically driven "global village". Mr, Rykwert has his worries, to be sure. but he does not see ruin or chaos everywhere. He defends the city as a human and social necessity. In Chandigarh, Canberra and New York he sees overall success; in New Delhi, Paris and Shanghai, large areas of falling. For Mr. Rykwert. a man on foot in the age of speeding virtual, good architecture may still show us a face where flaneurs can read the story of their urban setting in familiar metaphors.

单选题As researchers learn more about how children's intelligence develops, they are increasingly surprised by the power of parents. The power of the school has been replaced by the home . To begin with, all the factors which are part of intelligence — the child's understanding of language, learning patterns, curiosity — are established well before the child enters school at the age of six. Study after has shown that even after school begins, children's achievements have been far more influenced by parents than by teachers, This is particularly true about leaning that is language-related, The school rather than the home is given credit for variations in achievement in subjects such as science. In view of their power it's sad to see so many parents not making the most of their intelligence. Until recently parents had been by educators who asked them not to educate their children. Many teachers now realize that children cannot be educated only at school and being asked to contribute both before and after the child enters school. Parents have been particularly afraid to teach reading at home. Of course, children shouldn't be pushed to read by their parents, but educators have discovered that reading is best taught individually — and the easiest place to do this is at home. Many four and five-year-olds who have been shown a few letters and taught their sounds will compose single words of their own with them even before they have been taught to read.

单选题The girls in their sixth grade class in East Palo Alto, California, all have the same access to computers as boys. But researchers say, by the time they get to high school, they are victims of what the researchers call a major new gender (性别) gap in technology. Janice Weinman of the American Association of University Women says, "Girls tend to be less comfortable than boys with the computer. They use it more for word processing rather than for problem solving, rather than to discover new ways in which to understand information." After re-examining a thousand studies, the American Association of University Women researchers found that girls make up only a small percentage of students in computer science classes. Girls consistently rate themselves significantly lower than boys in their ability and confidence in using computers. And they use computers less often than boys outside the classroom. An instructor of a computer lab says he"s already noticed some differences. Charles Cheadle of Cesar Chavez School says, "Boys are not so afraid they might do something that will harm the computer, whereas girls are afraid they might break it somehow." Six years ago, the software company Purple Moon noticed that girls" computer usage was falling behind boys. Karen Gould says, "The number one reason girls told us they don"t like computer games is not that they"re too violent, or too competitive. Girls just said they"re incredibly boring." Purple Moon says it found what girls want, characters they can relate to and story lines relative to what"s going on in their own lives. Karen Gould of Purple Moon Software says, "What we definitely found from girls is that there is no intrinsic (固有的) reason why they wouldn"t want to play on a computer; it was just a content thing." The sponsor of the study says it all boils down to this: the technology gender gap that separates the girls from the boys must be closed if women are to compete effectively with men in the 21st century.

单选题On the surface, AIDS appears to have barely touched Asia so far, and the few cases reported involve mainly foreigners, female and male prostitutes(妓女) and imported blood. But complacency could be a fatal error. Experts have no doubts that the reported cases represent only the tip of an epidemic iceberg; many more people are infected than cases reported, in part because the virus takes five to seven years from infection to develop into AIDS. Says Dr. Jonathan Mann, director of the Special Program on AIDS of the World Health Organization: "AIDS is knocking on the door of Asia." Yet because AIDS is occurring later in Asia than in other continents, Asians can benefit from the knowledge gained at a heavy price elsewhere: AIDS can be transmitted through heterosexual as well as homosexual contact and prevention through education is the key—indeed the only—defense so far available. In the words of Dr. Mann, "the opportunity for protection of Asia against widespread dissemination of HIV"—the AIDS virus—"is obvious and may be vital to the future of the continent." In contrast to Asia, Africa had no warning at all when the disease began to appear there. Today, several million men, women and children may already be affected. Here is a Reader"s Digest report on the African crisis, followed by detailed information on AIDS and how it can be prevented.

单选题Eco-tourism—travel that preserves the environment and promotes the welfare of local people— continues to gain force. Impressed by the success of countries like Costa Rica and Ecuador, which have lured flocks of travelers for mountain treks and jungle safaris, a growing number of regions across tile globe are turning to eco-tourism as a strategy' for economic growth. Omar Bongo, the president of Gabon, a developing country in west central Africa, bas set aside about 10 percent of the country's landmass for 13 national parks. Green Visions, a tourism and environment protection company, based in Sarajevo. Bosnia-Herzegovina, is pioneering an eco-tourism development plan in Central Europe with "green adventures" that promote environmental principles and support local businesses. Even Greece, better known for its pumping night life and archaeological monuments, devotes a section of its national tourism' Web site to "Greek nature" and eco-tourism. Over the last four years, at least 48 countries, from Puerto Rico to Portugal, have created or started to define a national strategy for eco-tourism development, according to a 2004 eco-tourism report by Mintel International Group, a market-research company based in Britain. Though eco-tourism has long conjured images of biodiversity hot spots in countries like Belize, parts of the United States are starting to embrace the trend too. For example, the Wisconsin Department of Tourism will begin testing a new certification program in March called Travel Green Wisconsin. Designed to encourage hotels and tour operators to reduce their environmental impact, the program is aimed at protecting the natural areas that play a significant role in defining the state as a tourist destination. If. successful, the program will be rolled out statewide next year. For businesses, eco-friendly initiatives not only offer marketing advantages but can help with the bottom line. Hotels can cut costs by doing everything from installing energy-saving light bulbs to asking travelers to reuse their towels. And some 58.5 million U.S. travelers, or 38 percent, would pay more to use travel companies that strive to protect and preserve the environment, according to a study by the Travel Industry Association of America sponsored by National Geographic Traveler. Of those travelers. 61 percent said they would pay 5 to 10 percent more to use such companies. However. selecting among the growing number of eco-friendly choices can be frightening, especially given the ever-broadening category, which now encompasses everything from basic campsites to high-end mountain lodges, lama trekking to motorcycle tours through the jungle. Enter the Sustainable Tourism Certification Network of the Americas—a partnership of certification programs, environmental groups, government organizations and others, led by the Rainforest. Alliance and the International Ecotourism Society—which aims to promote sustainability and higher environmental and social standards for tourism. In September, the network designed a series of baseline criteria for certification to help generate credibility among members and promote local conservation. This year, the document will be put up for public consultation before being fully ratified. "Certification is a way for us to avoid green washing," the practice of promoting something as ecotourism while behaving in an environmentally irresponsible way, said Ronald Sanabria. director of sustainable tourism at the Rainforest Alliance. "Certification for us is a tool to avoid that and to ensure third-party assessments of requirements and really prove the company./
