单选题{{B}}Questions 11-15 are based on the following passage:{{/B}} Venus (金星) is known as the earth's "twin" because the two planets are so like each other in size. The diameter of Venus is about 7, 520 miles (12,100 km. ), smaller than that of the earth. No other planet comes closer to the earth than Venus. At its nearest approach it is about 25,000,000 miles (40,2000,000 km. ) away. As seen from the earth, Venus is the first planet or star that can be seen in the western sky in the evening. At other times, it is the last planet or star that can be seen in the eastern sky in the morning. When Venus is near its brightest point, it can be seen in daylight. Early astronomers called the object that appeared in the evening Hesperus, and Phosphorus in the morning. Later, they realized these two objects were the same planet. They named it Venus in honor of the Roman goddess of love and beauty.

单选题The destruction of our natural resources and contamination of our food supply continue to occur, largely because of the extreme difficulty in affixing (把……固定) legal responsibility on those who continue to treat our environment with reckless abandon (放任). Attempts to prevent pollution by legislation, economic incentives and friendly persuasion have been met by lawsuits, personal and industrial denial and long delays—not only in accepting responsibility, but more importantly, in doing something about it. It seems that only when government decides it can afford tax incentives or production sacrifices is there any initiative for change. Where is industry's and our recognition that protecting mankind's great treasure is the single most important responsibility? If ever there will be time for environmental health professionals to come to the frontlines and provide leadership to solve environmental problems, that time is now. We are being asked, and, in fact, the public is demanding that we take positive action. It is our responsibility as professionals in environmental health to make the difference. Yes, the ecologists, the environmental activists and the conservationists serve to communicate, stimulate thinking and promote behavioral change. However, it is those of us who are paid to make the decisions to develop, improve and enforce environmental standards, I submit, who must lead the charge. We must recognize that environmental health issues do not stop at city limits, county lines, state or even federal boundaries. We can no longer afford to be tunnel-visioned in our approach. We must visualize issues from every perspective to make the objective decisions. We must express our views clearly to prevent media distortion and public confusion. I believe we have a three-part mission for the present. First, we must continue to press for improvements in the quality of life that people can make for themselves. Second, we must investigate and understand the link between environment and health. Third, we must be able to communicate technical information in a form that citizens can understand. If we can accomplish these three goals in this decade, maybe we can finally stop environmental degradation, and not merely hold it back. We will then be able to spend pollution dollars truly on prevention rather than on bandages.

单选题{{B}}Text 2{{/B}} I was addressing a small gathering in a suburban Virginia living room-a women's group that had invited men to join them. Throughout the evening, one man had been particularly talkative, frequently offering ideas and anecdotes, while his wife sat silently beside him on the couch. Toward the end of the evening, I commented that women frequently complain that their husbands don't talk to them. This man quickly nodded in agreement. He gestured toward his wife and said, "She's the talker in our family. " The room burst into laughter; the man looked puzzled and hurt. "It's true," he explained. " When I come home from work I have nothing to say. If she didn't keep the conversation going, we'd spend the whole evening in silence. " This episode crystallizes the irony that although American men tend to taXk more than women in public situations, they often talk less at home. And this pattern is wreaking havoc with marriage. The pattern was observed by political scientist Andrew Hacker in the late 1970s. Sociologist Catherine Kohler Riessman reports in her new book Divorce Talk that most of the women she interviewed-but only a few of the men-gave lack of communication as the reason for their divorces. Given the current divorce rate of nearly 50 percent, that amounts to millions of cases in the United States every year-a virtual epidemic of failed conversation. In my own research, complaints from women about their husbands most often focused not on tangible inequities such as having given up the chance for a career to accompany a husband to his, or doing far more than their share of daily life-support work like cleaning, cooking and social arrangements. Instead, they focused on communication: "He doesn't listen to me. " "He doesn't talk to me. " I found, as Hacker observed years before, that most wives want their husbands to be, first and foremost, conversational partners, but few husbands share this expectation of their wives. In short, the image that best represents the current crisis is the stereotypical cartoon scene of a man sitting at the breakfast table with a newspaper held up in front of his face, while a woman glares at the back of it, wanting to talk.

单选题What do the extraordinarily successful companies have in common? To find out, we looked for correlations. We know that correlations are not always reliable; nevertheless, in the 27 survivors, our group saw four shared personality traits that could explain their longevity. Conservatism in financing. The companies did not risk their capital gratuitously. They understood the meaning of money in an old-fashioned way; they knew the usefulness of spare cash in the kitty. Money in hand allowed them to snap up options when their competitors could not. They did not have to convince third-party financiers of the attractiveness of opportunities they wanted to pursue. Money in the kitty allowed them to govern their growth and evolution. Sensitivity to the world around them. Whether they had built their fortunes on knowledge (such as Dupont’s technological innovations) or on natural resources (such as the Hudson's Bay Company's access to the furs of Canadian forests), the living companies in our study were able to adapt themselves to changes in the world around them. As wars, depressions, technologies, and politics surged and ebbed, they always seemed to excel at keeping their feelers out, staying attuned to whatever was going on. For information, they sometimes relied on packets carried over vast distances by portage and ship, yet they managed to react in a timely fashion to whatever news they received. They were good at learning and adapting. Awareness of their identity. No matter how broadly diversified the companies were, their employees all felt like parts of a whole. Lord Cole, chairman of Unilever in the 1960s, for example, saw the company as a fleet of ships. Each ship was independent, but the whole fleet was greater than the sum of its parts. The feeling of belonging to an organization and identifying with its achievements is often dismissed as soft. But case histories repeatedly show that a sense of community is essential for long-term survival. Managers in the living companies we studied were chosen mostly from within, and all considered themselves to be stewards of a longstanding enterprise. Their top priority was keeping the institution at least as healthy as it had been when they took over. Tolerance of new ideas. The long-lived companies in our study tolerated activities in the margin: experiments and eccentricities that stretched their understanding. They recognized that new businesses may be entirely unrelated to existing businesses and that the act of starting a business need not be centrally controlled. W.R. Grace, from its very beginning, encouraged autonomous experimentation. The company was founded in 1854 by an Irish immigrant in Peru and traded in guano, a natural fertilizer, before it moved into sugar and tin. Eventually, the company established Pan American Airways. Today it is primarily a chemical company, although it is also the leading provider of kidney dialysis services in the United States. By definition, a company that survives for more than a century exists in a world it cannot hope to control. Multinational companies are similar to the long-surviving companies of our study in that way. The world of a multinational is very large and stretches across many cultures. That world is inherently less stable and more difficult to influence than a confined national habitat. Multinationals, like enduring companies, must be willing to change in order to succeed. These four traits form the essential character of companies that have functioned successfully for hundreds of years. Given this basic personality, what priorities do the managers of living companies set for themselves and their employees?

单选题Working memory, or short-term memory, involves the ability to hold and use information in the immediate future. 21 is only held in working memory for about 20 seconds. The challenge that students 22 is to move information from their working memories into their long-term memories. If they don"t do this in about the first few minutes after receiving the information, that information can be lost. To keep this newly learned material from 23 away, it needs to enter the network of the brain"s wiring. After repeated practice, working memories are set down as permanent neuronal (神经的) circuits 24 to be activated (激活) when the information is needed. When a memory has been recalled 25 its neuronal circuits are more highly developed because of their repeated activation. 26 exercising a muscle, these circuits then become more efficient and easier to access and activate. Practice results 27 repeated stimulation of the memory circuit. Like hikers along a path 28 eventually leave a depression in the road, repeated practice stimulates cells in the memory circuit such that the circuit is reinforced and becomes 29 . This means it can be quickly turned from off to on, and switched 30 through a variety of cues coming in from the senses.

单选题We all know that it is possible for ordinary people to make their homes on the equator (赤道), although often they may feel uncomfortably hot there. Millions do it. But as for the North Pole (北极)--we know that it is not only a dangerously cold place, but that people like you and me would find it quite impossible to live there. At the present time only the scientists and explorers can do so, and they use special equipment. Men had been traveling across and around the equator on wheels, on their feet or in ships for thousands of years; but only a few men, with great difficulty and in very recent time, have ever crossed the ice to the North Pole. So it may surprise you to learn that, when traveling by air, it is really safer to fly over the North Pole than over the equator. Of course, this is not true about landings in the polar region (which passenger aeroplanes do not make), but the weather, if we are flying at a height of 5000 meters above the Pole, is a delight. At 4 000 meters and More above the earth you can always be sure that you will not see a cloud in the sky as far as the eye can reach. In the tropics (热带), on the other hand, you are not certain to keep clear of bad weather even at such heights as 18 000 or 20 000 meters. Aeroplanes can't climb as high or as quickly in cold air as in warm air. Nor can clouds. In practice, this is an advantage to the aeroplane, which is already at a good height when it reaches the polar region and so does not need to climb, while at the same time cold air keeps the clouds down low.
