单选题The January fashion show, called FutureFashion, exemplified how far green design has come. Organized by the New York-based nonprofit Earth Pledge, the show inspired many top designers to work with sustainable fabrics for the first time. Several have since made pledges to include organic fabrics in their lines. The designers who undertake green fashion still face many challenges. Scott Hahn, cofounder with Gregory of Rogan and Loomstate, which uses all-organic cotton, says high-quality sustainable materials can still be tough to find. " Most designers with existing labels are finding there aren't comparable fabrics that can just replace what you're doing and what your customers are used to," he says. For example, organic cotton and non-organic cotton are virtually indistinguishable once woven into a dress. But some popular synthetics, like stretch nylon, still have few eco-friendly equivalents. Those who do make the switch are finding they have more support. Last year the influential trade show Designers & Agents stopped charging its participation fee for young green entrepreneurs who attend its two springtime shows in Los Angeles and New York and gave special recognition to designers whose collections are at least 25% sustainable. It now counts more than 50 green designers, up from fewer than a dozen two years ago. This week Wal-Mart is set to announce a major initiative aimed at helping cotton farmers go organic: it will buy transitional (过渡型的) cotton at higher prices, thus helping to expand the supply of a key sustainable material. " Mainstream is about to occur," says Hahn. Some analysts are less sure. Among consumers, only 18% are even aware that ecofashion exists, up from 6% four years ago. Natalie Hormilla, a fashion writer, is an example of the unconverted consumer. When asked if she owned any sustainable clothes, she replied: "Not that I'm aware of. " Like most consumers, she finds little time to shop, and when she does, she's on the hunt for "cute stuff that isn't too expensive. " By her own admission, green just isn't yet on her mind. But—thanks to the combined efforts of designers, retailers and suppliers—one day it will be.

单选题 A group of 11 delegates from the Chinese university returned home last week. They came in second place with 13 other university teams. The conference is the world's largest university-level UN simulation. It is held each April, for a week, in New York, to give students a chance to debate international affairs. It is meant to mirror the real-life business of the UN. Teams from more than 23 countries gathered this year to discuss and debate serious issues such as the AIDS epidemic and water shortages. Some UN senior staff members, U. S. professors, and former student participants formed the judge panel. The Chinese team applied to take part in the event and was assigned to represent Japan this year, working on various committees and arguing Japan's position on resolutions to problems like international migration. According to Li Xiaocong, the Chinese team leader, their efforts in finding approaches to resolutions made them stand out. Li attributes their success to "solid training".

单选题{{B}}Text 2{{/B}} Most human beings actually decide before they think. When any human being executive, specialized expert, or person in the street—encounters a complex issue and forms an opinion, often within a matter of seconds, how thoroughly has he or she explored the implications of the various courses of action? Answer: not very thoroughly. Very few people, no matter how intelligent or experienced, can take inventory of the many branching possibilities, possible outcomes, side effects, and undesired consequences of a policy or a course of action in a matter of seconds. Yet, those who pride themselves on being decisive often try to do just that. And once their brains lock onto an opinion, most of their thinking thereafter consists of finding support for it. A very serious side effect of argumentative decision making can be a lack of support for the chosen course of action on the part of the "losing" faction. When one faction wins the meeting and the others see themselves as losing, the battle often doesn't end when the meeting ends. Anger, resentment, and jealousy may lead them to sabotage the decision later, or to reopen the debate at later meetings. There is a better way. As philosopher Aldous Huxley said, "It isn't who is right, but what is right, that counts. " The structured-inquiry method offers a better alternative to argumentative decision making by debate. With the help of the Internet and wireless computer technology, the gap between experts and executives is now being dramatically closed. By actually putting the brakes on the thinking process, slowing it down, and organizing the flow of logic, it's possible to create a level of clarity that sheer argumentation can never match. The structured-inquiry process introduces a level of conceptual clarity by organizing the contributions of the experts, then brings the experts and the decision makers closer together. Although it isn't possible or necessary for a president or prime minister to listen in on every intelligence analysis meeting, it's possible to organize the experts' information to give the decision maker much greater insight as to its meaning. This process may somewhat resemble a marketing focus group ; it's a simple, remarkably clever way to bring decision makers closer to the source of the expert information and opinions on which they must base their decisions.

单选题{{B}}Passage Two{{/B}} To paraphrase 18th century statesman Edmund Burke, "all that is needed for the triumph of a misguided cause is that good people do nothing. One such cause now seeks to end biomedical research because of the theory that animals have rights ruling out their use in research. Scientists need to respond forcefully to animal rights advocates, whose arguments are confusing the public and thereby threatening advances in health knowledge and care. Leaders of the animal rights movement target biomedical research because it depends on public funding, and few people understand the process of health care research. Hearing allegations of cruelly to animals in research settings, many are perplexed that anyone would deliberately harm an animal. For example, a grandmotherly woman staffing an animal rights booth at a recent street fair was distributing a brochure that encouraged readers not to use anything that opposed immunizations, she wanted to know if vaccines come from animal research. When assured that they do, she replied, "Then I would have to say yes." Asked what will happen when epidemics return, she said, "Don't worry, scientists will find some way of using computers." Such well-meaning people just don's understand. Scientists must communicate their message to the public in a compassionate, understandable way in human terms, not in the language of molecular biology. We need to make clear the connection between animal research and a grandmother's hip replacement, a father's bypass operation a baby's vaccinations, and even a pet's shots. To those who are unaware that animal research was needed to produce these treatments, as well as new treatments and vaccines, animal research seems wasteful at best and cruel at worst. Much can be done. Scientists could "adopt" middle school classes and present their own research. They should be quick to respond to letters to the editor, lest animal rights misinformation go unchallenged and ac quire a deceptive appearance of truth. Research institutions could be opened to tours, to show that laboratory animals receive humane care Finally, because the ultimate stakeholders are patients, the health research community should actively recruit to its cause not only well-known personalities such as Stephen Cooper, who has made courageous statements about the value of animal research, but all who receive medical treatment. If good people do nothing there is a real possibility that an uninformed citizenry will extinguish the precious embers of medical progress.

单选题If you stand there you obscure our view of the race.

单选题For centuries, explorers have risked their lives venturing into the unknown for reasons that were to varying degrees economic and nationalistic. Columbus went west to look for better trade routes to the Orient and to promote the greater glory of Spain, Lewis and Clark journeyed into the American wilderness to find out what the U. S. had acquired when it purchased Louisianan, and the Apollo astronauts rocketed to the moon in a dramatic show of technological muscle during the cold war. Although their missions blended commercial and political-military imperatives, the explorers involved all accomplished some significant science simply by going where no scientists had gone before. Today Mars looms as humanity"s next great terra incognita (未探明之地). And with doubtful prospects for a short-term financial return, with the cold war a rapidly fading memory and amid a growing emphasis on international cooperation in large space ventures, it is clear that imperatives other than profits or nationalism will have to compel human beings to leave their tracks on the planet"s reddish surface. Could it be that science, which has long played a minor role in exploration, is at last destined to take a leading role? The question naturally invites a couple of others: are there experiment that only human could do on Mars? Could those experiments provide insights profound enough to justify the expense of sending people across interplanetary space? With Mars the scientific stakes are arguably higher than they have ever been. The issue of whether life ever existed on the planet, and whether it persists to this day, has been highlighted by mounting evidence that the Red Planet once had abundant stable, liquid water and by the continuing controversy over suggestions that bacterial fossils rode to Earth on a meteorite (陨石) from Mars. A more conclusive answer about life on Mars, past or present, would give researchers invaluable data about the range of conditions under which a planet can generate the complex chemistry that leads to life. If it could be established that life arose independently on Mars and Earth, the finding would provide the first concrete clues in one of the deepest mysteries in all of science: the prevalence of life in the universe.
