单选题 These days a green building means more than just the color of the paint. Green building can also refer to environmentally friendly houses, factories and offices. Buildings account for 65 percent of total U.S. electricity use. But green buildings can reduce energy and water use. Also, the buildings are often located near public transportation such as buses and subways, so that people can drive their cars less. That could be good for the environment, because cars use lots of natural resources such as gasoline, and give off pollution. Green buildings are often built on previously developed land, so that the buildings don't destroy forests or other wild habitats(栖息地). Marry Dettling is a project manager for a building that puts these ideas into action. The Solaire has been called the country's first green residential high-rise building. According to Dealing, "We've reduced our energy consumption by one-third and our water by 50 percent. " Not everyone is leaping to move into a green building, however. Some people think that features such a solar panels cost more money than more traditional energy sources. Despite this, Dettling hopes that green buildings will become common in the future. "It's going to be big," she said.

单选题Passage 9 One of the most pressing challenges that the United States--and indeed, the world--will face in the next few decades is how to alleviate the growing stress that human activities are placing on the environment. The consequences are just too great to ignore. Wildlife habitats are being degraded or disappearing altogether as new developments take up more land. Plant and animal species are becoming extinct at a greater rate now than at any time in Earth's history. As many as 30 percent of the world's fish stocks are overexploited. And the list goes on. Yet, there is reason to have hope for the future. Advances in computing power and molecular biology are among the tremendous increases in scientific capability that are helping researchers gain a better understanding of these problems. Recent developments in science and technology could provide the basis for some major, and timely actions that would improve our understanding of how human activities affect the environment. One priority for research is improving hydrological forecasting. It has been estimated that the world's water use could triple in the next two decades. Already, widespread water shortages have occurred in parts of China, India, North Africa, and the Arabian Peninsula. The need for water also is taking its toll on freshwater ecosystems in the United States. Only 2 percent of the nation's streams are considered in good condition, and close to 40 percent of native fish species are rare to extinct. Using a variety of new remote sensing tools, scientists can learn more about how precipitation affects water levels, how surface water is generated and transported, and how changes in the landscape affect water supplies. To prevent outbreaks of infectious diseases in plants, animals, and humans, more study is needed on how pathogens, parasites, and disease-carrying species--as well as humans and other species they infect--are affected by changes in the environment. The overuse of antibiotics both in humans and in farm animals has contributed to the growth of antibiotic-resistant microorganisms. Researchers can take advantage of new technologies in genetics and computing to better monitor and predict the effects that environmental changes might have on disease outbreaks. Humans have made alterations to Earth's surface--such as tropical deforestation, reduction of surface and ground water, and massive development--so dramatic that they approach the levels of transformation that occurred during glacial periods. Such alterations cause changes in local and regional climate, and will determine the future of agriculture. Recent advances in data collection and analysis should be used to document and better understand the causes and consequences of changes in land cover and use.

单选题 Experts predict that China's healthcare market will have an annual growth of 6 to 8 percent in the next few years, making it one of the potentially most prosperous. In Shanghai, annual medical expenditure is estimated to be 16 billion yuan (U. S. 93 billion). With an increasingly {{U}}(31) {{/U}} population, the growing consumption power and longer life {{U}}(32) {{/U}} of local residents, the medical market has great opportunities. However l limited medical resources cannot meet people's needs {{U}}(33) {{/U}} financial deficits in State-owned hospitals. {{U}}(34) {{/U}}, there is room for a range of different medical organizations. As is the case with many State-owned enterprises, public hospitals in the past half century have learned a lot of bad habits: {{U}}(35) {{/U}} management, over-staffing and bureaucratic operating procedures.

单选题Customer: Could you hold the door open for a moment, please?Salesman: Certainly.

单选题Much has been written about the potential for management to become isolated from customers and employees. This phenomenon often occurs not just within top management, but also within middle management. I've seen this isolation phenomenon in many companies. The symptoms are quite apparent: Managers spend a great deal of time talking to themselves and studying operating numbers. They spend precious little time with customers or with employees, trying to understand the system of the business. And when they do spend time with them, they often do not probe deeply into needs, concerns, and opportunities. This phenomenon, often referred to as being "internally focused", can be tremendously insidious (隐伏陷害的). Although the need for understanding and spending time with customers has been well documented, I find few managers spending time in the field. The benefits of doing so are clear. A visit with your counterparts at customers' distribution centers, for example, not only builds relation ships that can prove useful when problems arise, but also uncovers numerous opportunities to enhance(增进，提高) your performance and deepen your company's linkage with those customers. There are many ways to connect with and understand employee perspectives(观点，看法). Some companies have found formal sessions in which senior managers solicit (恳求，请求) ideas from employees to be very useful. These can be run either as focus groups or as structured discussions. Managers also should exploit every opportunity to gather organizational knowledge from employees. Some successful managers collect employees' opinions by what often is referred to as "managing by walking around" or the "10-minute cup of coffee". They, may, for example, go to employees' offices and solicit their opinions. Or at lunch or when they take a cup of coffee, they "mix with the troops" and solicit their input. Rather than talk about the latest game, you can solicit employees' ideas by asking questions like: What are you working on? How's it going? What's good about our organization? What could be better? How could we better serve our customers or improve our processes? What do you think we should be doing differently? You'll be surprised at how valuable a "10-minute cup of coffee" together with a brief conversation with an employee can be. It will make you a more effective manager.

单选题 Do you remember all those years when scientists argued that smoking would kill us but the doubters insisted that we didn't know for sure? That the evidence was inconclusive, the science uncertain? That the antismoking lobby was out to destroy our way of life and the government should stay out of the way? Lots of Americans bought that nonsense, and over three decades, some 10 million smokers went to early graves. There are upsetting parallels today, as scientists in one wave after another try to awaken us to the growing threat of global warming. The latest was a panel from the National Academy of Sciences, enlisted by the White House, to tell us that the Earth's atmosphere is definitely warming and that the problem is largely man-made. The clear message is that we should get moving to protect ourselves. The president of the National Academy, Bruce Alberts, added this key point in the preface to the panel's report "Science never has all the answers but science does provide us with the best available guide to the future, and it is critical that out nation and the world base important policies on the best judgments that science can provide concerning the future consequences of present actions. " Just as on smoking voices now come from many quarters insisting that the science about global warming is incomplete, that it's OK to keep pouring fumes into the air until we know for sure. This is a dangerous game: by the 100 percent of the evidence is in, it may be too late. With the risks obvious and growing, a prudent people would take out an insurance policy now. Fortunately, the White House is starting to pay attention. But it's obvious that a majority of the president's advisers still don't take global warming seriously. Instead of a plan of action, they continue to press for more research—a classic case of "paralysis by analysis". To serve as responsible stewards of the planet, we must press forward on deeper atmospheric and oceanic research. But research alone is inadequate. If the Administration won't take the legislative initiative, Congress should help to begin fashioning conservation measures A bill by Democratic Senator Robert Byrd of West Virginia, which would offer financial incentives for private industry is a promising start. Many see that the country is getting ready to build lots of new power plants to meet our energy needs. If we are ever going to protect the atmosphere, it is crucial that those new plants be environmentally sound.

单选题Excitement, fatigue, and anxiety can all be detected from someone's blinks, according to psychologist John Stern (21) Washington University in St. Louis. Stern specialized in the study on these tiny twitches, using them as sensitive (22) of how the brain works. "I use blinks as a psychological measure to make (23) about thinking because I have very little (24) in what you tell me about what you are thinking." He says. "If I ask you the question, 'what does the phrase a rolling stone gathers no moss mean?' you can't tell me (25) you've started looking for the answer. But I can, by watching your eyes." Blinks also tell Stern when you have understood his question--often long before he's finished asking it--and when you've found an answer or part of (26) . "We blink at times (27) are psychologically important." He says. "You have listened to a question, you understand it, (28) you can take time out for a blink. Blinks are (29) marks.

People blink later, for example, (33) they have to memorize six numbers instead of two. "You don't blink," he says, "until you have (34) the information to some short-term memory store." And if subjects are cued (35) the set of numbers is coming, say, five seconds, they'll curb their blinks until the task is (36) .

单选题 For an increasing number of students at American universities, Old is suddenly in. The reason is obvious: the graying of America means jobs. Coupled with the aging of the baby-boom (生育高峰) generation, a longer life span means that the nation's elderly population is bound to expand significantly over the next 40 years. By 2040, 25 percent of all Americans will be older than 65, up from 14 percent in 1995. The change poses profound questions for government and society, of course. But it also creates career opportunities in medicine and health professions, and in law and business as well. "In addition to the doctors, we're going to need more sociologists, biologists, urban planners and specialized lawyers," says Professor Edward Schneider of the University of Southern California's (USC) School of Gerontology (老年学). Lawyers can specialize in "elder law", which covers everything from trusts and estates to nursing-home abuse and age discrimination (岐视). Businessmen see huge opportunities in the elder market because the baby boomers, 74 million strong, are likely to be the wealthiest group of retirees in human history. "Any student who combines an expert knowledge in gerontology with, say, an MBA or law degree, will have a license to print money," one professor says. Margarite Santos is a 21-year-old senior at USC. She began college as a biology major but found she was "really bored with bacteria." So she took a class in gerontology and discovered that she liked it. She says, "I did volunteer work in retirement homes and it was very satisfying."
