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./

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{{B}}Text 2{{/B}} The period of adolescence, i.e., the period between childhood and adulthood, may be long or short, depending on social expectations and on society's definition as to what constitutes maturity and adulthood. In primitive societies adolescence is frequently a relatively short period of time, while in industrial societies with patterns of prolonged education coupled with laws against child labor, the period of adolescence is much longer and may include most of the second decade of one's life. Furthermore, the length of the adolescent period and the definition of adulthood status may change in a given society as social and economic conditions change. Examples of this type of change are the disappearance of the frontier in the latter part of the nineteenth century in the United States, and more universally, the industrialization of an agricultural society. In modern society, ceremonies for adolescence have lost their formal recognition and symbolic significance and there no longer is agreement as to what constitutes initiation ceremonies. Social ones have been replaced by a sequence of steps that lead to increased recognition and social status. For example, grade school graduation, high school graduation and college graduation constitute such a sequence, and while each step implies certain behavioral changes and social recognition, the significance of each depends on the socio-economic status and the educational ambition of the individual. Ceremonies for adolescence have also been replaced by legal definitions of status roles, rights, privileges and responsibilities. It is during the nine years from the twelfth birthday to the twenty-first that the protective and restrictive aspects of childhood and minor status are removed and adult privileges and responsibilities axe granted. The twelve-year-old is no longer considered a child and has to pay full fare for train, airplane, theater and movie tickets. Basically, the individual at this age loses childhood privileges without gaining significant adult rights. At the age of sixteen the adolescent is granted certain adult rights which increases his social status by providing him with more freedom and choices. He now can obtain a driver's license: he can leave public schools; and he can work without the restrictions of child labor laws. At the age of eighteen the law provides adult responsibilities as well as rights: the young man can now be a soldier, but he also can marry without parental permission. At the age of twenty-one the individual obtains his full legal rights as an adult. He now can vote, he can buy liquor, he can enter into financial contracts, and he is entitled to run for public office. No additional basic rights are acquired as a function of age after majority status has been attained. None of these legal provisions determine at what point adulthood has been reached but they do point to the prolonged period of adolescence.

单选题{{B}}Text 4{{/B}} Germany's chimney sweeps—hallowed as bringers of good luck, with their black top hats and coiled-wire brushes— are under attack. Last week the European Commission's directorate for the internal market revived proceedings against an antiquated German law that protects sweeps against competition. The country's chimney sweeps enjoy a near-perfect monopoly. Germany is divided into around 8000 districts, each ruled by its own master sweep who usually employs two more sweeps. Although this is a private enterprise, the maintenance and inspection service provided is compulsory and prices are set by the local authority: sweeps cannot stray outside their district, nor can householders change their sweep even if they loathe him. This rule cuts both ways. "There are some customers I can't stand either," says one Frankfurt sweep. The rationale is simple: chimney-sweeping and related gas and heating maintenance in Germany are treated as a matter of public safety. Annual or semi-annual visits are prescribed, keeping the sweeps busy all year round. For centuries, chimney-sweeps in Europe were a wandering breed. But in 1937 the chimney-sweep law was revised by Heinrich Himmler, then the acting interior minister. His roles tied chimney sweeps to their districts and decreed that they should be German, to enable him to use sweeps as local spies. The law was updated in 1969, leaving the local monopolies in place but opening up the profession, in theory at least, to non-Germ, ans. But in practice few apply. Four years ago a brave Pole qualified as a master in Kaiserslautern, according to a fellow student, and this year an Italian did so in the Rhineland Palatinate. But he, like most newly qualified German masters, will spend years on a waiting list before he gets his own district. The European Commission would like to see a competitive market in which people can choose their own sweeps, just as they choose builders or plumbers. It first opened infringement proceedings in 2003, and the German government of the time promised to change the law but failed to do so. And despite the huffing and puffing from Brussels, tile government is still reluctant to dismantle its antiquated system on safety grounds. The number of deaths from carbon-monoxide poisoning in Germany is around one-tenth that in France or Belgium, claims the Frankfurt sweep. So Germans are likely to be stock with their neighbourhood Schornsteinfegers—whether they can stand each other or not—for some time to come.

单选题Of greatest interest to those concerned with the environmental aspects of solid waste management is the issue of—and the need for—resource recovery and recycling. To many Americans, there is perhaps no greater symbol of our imbalance with nature and our mal-adaptation to its realities than the fact that we discard millions of tons of wastes every year which do, in act, have value. The American people realize now that trash need not be mere junk. It has the potential of becoming a significant vein or resources, a mother lode of opportunity for men of vision who can see beyond the horizon. The American people are right. And those who serve them can no longer view solid waste management solely in terms of collection and disposal. However, something more than the magic of science and technology is required to convert all this waste back into useful resources. In fact, in proportion to consumption, resource: recovery has been steadily losing ground in recent years in virtually every materials sector. Approximately 200 million tons of paper, iron, steel, glass, nonferrous metals, textiles, rubber and plastics flow through the economy yearly--and materials weighing roughly the same leave the economy again as waste. In spite of neighbor hood recycling projects, container recovery depots, paper drives, anti-litter campaigns, local ordinances banning the non-returnable bottle, and file emergence of valuable new technological approaches, only a trickle of the "effluence of affluence" is today being diverted from the municipal waste stream. The principal obstacles are economic and institutional, not technological. The cost of recovering, processing and transporting wastes is so high that the resulting products simply cannot compete, economically, with virgin materials. Of course, it the true costs of such economic "externalities" as environmental impact associated with virgin materials use were reflected in production costs and if there were no subsidies to virgin materials in the form of depletion allowances and favorable freight rates, the use of secondary materials would become muck more attractive. But they are not now. There are no economic or technical events on the horizon, short of governmental intervention, that would indicate a reversal of this trend. If allowed to continue to operate as it does now, the economic system will continue to select virgin raw materials in preference to wastes. This fact should be etched into the awareness of those who look to recycling as a way out of the solid waste management dilemma.

单选题{{B}}阅读理解三{{/B}} {{B}}Questions 11 to 15 are based on the following passage.{{/B}} Most of us have seen a dog staring at, sometimes snarling at, and approaching a reflection of itself. For most animals, seeing their own image in a mirror acts as a social stimulus. But does the dog recognize itself, or does the reflection simply signal a potential companion or threat? This question is interest for a number of reasons. Apart from curiosity about the level of animals' understanding, research on self-recognition in animals has several benefits. It provides some insight into the evolutionary significance of this skill of self-recognition and into the level and kinds of cognitive competence that the skill requires. Such research also indicates the kinds of learning experiences that determine the development of self-recognition. In addition, work with animals fosters the use of techniques that are not dependent on verbal responses and that may therefore be suitable for use with preverbal children. The evidence indicates that dogs and almost all other nonhumans do not recognize themselves. In a series of clever experiments, however, Gallup has shown that the chimpanzee does have this capacity. Gallup exposed chimpanzees in a small cage to a full-length mirror for ten consecutive days. It was observed that over this period of time the number of self-directed responses increased. These behaviors included grooming parts of the body while watching the results, guiding fingers in the mirror, and picking at teeth with the aid of the mirror. Describing one chimp, Gallup said, "Marge used the mirror to play with and inspect the bottom of her feet; she also looked at herself upside down in the mirror while suspended by her feet from the top of the cage; she was also observed to stuff celery leaves up her nose using the mirror for purposes of visually guiding the stems into each nostril." Then the researchers devised a further test of self-recognition. The chimps were anesthetized and marks were placed over their eyebrows and behind their ears, areas the chimps could not directly observe. The mirror was temporarily removed from the cage, and baseline data regarding their attempts to touch these areas were recorded. The data clearly suggest that chimps do recognize themselves, or are self-aware, for their attempts to touch the marks increased when they viewed themselves. Citing further evidence for this argument, Gallup noted that chimpanzees with no prior mirror experience did not direct behavior to the marks when they were first exposed to the mirror; that is, the other chimpanzees appeared to have remembered what they looked like and do have responded to the marks because they noticed changes in their appearance.
