单选题 Passage 6 An important factor of leadership is attraction. This does not mean attractiveness in the ordinary sense, for that is a born quality {{U}}(1) {{/U}} our control. The leader has, nevertheless, to be a magnet; a central figure towards whom people are {{U}}(2) {{/U}}. Magnetism in that sense depends, first of all, {{U}}(3) {{/U}} being seen. There is a type of authority which can be {{U}}(4) {{/U}}. from behind closed doors, but that is not leadership. {{U}}(5) {{/U}} there is movement and action, the true leaders is in the forefront and may seem, indeed, to be everywhere at once. He has to become a legend; the {{U}}(6) {{/U}} for anecdotes, whether true or {{U}}(7) {{/U}}; an important character. One of the simplest devices is to be absent {{U}}(8) {{/U}} the occasion when the leader might be {{U}}(9) {{/U}} to be there, enough in itself to start a rumor about the vital business {{U}}(10) {{/U}} has detained him. To {{U}}(11) {{/U}} up for this, he can appeal when least expected, giving rise to another story about the interest he can display {{U}}(12) {{/U}} things which other folks might {{U}}(13) {{/U}} as trivial. With this gift for {{U}}(14) {{/U}} curiosity, the leader always combines a reluctance to talk about himself. His interest is {{U}}(15) {{/U}} in other people; he questions them and encourages them to talk and then remembers all {{U}}(16) {{/U}} is relevant. He never leaves a party {{U}}(17) {{/U}} he has mentally field a minimum dossier (档案) on {{U}}(18) {{/U}} present, ensuring that he knows {{U}}(19) {{/U}} to say when he meets them again. He is not artificially extrovert but he would usually rather listen {{U}}(20) {{/U}} talk. Others realize gradually that his importance needs no proof.

单选题{{B}}Questions 16-20 are based on the following passage:{{/B}} It might be supposed that greater efficiency could be achieved if several people worked together to solve a problem than if only one individual works on it. Although groups often may increase the motivation of their members to deal with problems, there are conflicts arising among members of a group. Problem solving needs the presence of an effective leader who not only provides direction, but also permits the orderly, constructive expression of different opinions; much of the leader's effort may be devoted to resolving differences. Success in problem solving also depends on the distribution of ability within a group. Although groups may reach a greater number of correct solutions, or may require less time to discover an answer, their efficiency is typically lower than that achieved by skilled individuals working alone. In brainstorming, a problem is presented to a group of people who then proceed to offer whatever they can think of. Theoretically these unrestricted suggestions increase the probability that at least some better solutions will appear. Nevertheless, studies show that when individuals work alone under similar conditions, performance tends to proceed more efficiently than it does in groups. Under special circumstances, however, a group may solve problems more effectively than a competent individual does. Group members may contribute different resources to a solutionthat no individual can achieve alone. Sometimes social demands may require group agreement on a single issue, as in making national economic or military policies under the governments. When only one among several solutions is correct, even if a group requires more time, it has a higher probability of identifying the right one than does an individual alone.

单选题{{B}}练习十七{{/B}} There are examples of what can be done by the retailer within his store, but perhaps the biggest opportunity for cost-reduction stems from cooperation between manufacturer and distributor in analyzing the total costs involved in moving the product from the factory to the shopper's basket. A helpful technique in this connection is the concept of "direct product profit" which is widely used in the United States. This is a technique for analyzing very precisely the costs and profits associated with each product line, with a view to isolating opportunities for cost reduction. For example, the in-store handling costs for particular item may be reduced if the manufacturer puts it in a large case or reduces the number of layers in the case. With the growing importance of prepackaging both for perishable items like meat and for non-food products, it is essential that the container should facilitate quick unloading and easy display. More obvious is the case for cooperation in reducing the costs of delivery and unloading; the night delivery experiment in Central London is an example of this. Many shops lack proper unloading facilities, often because the local authorities or private developers who built them were not aware of what was needed. Many retailers do not employ modern handling techniques. Some consumer goods manufacturers, such as Unilever, are playing a big part in streamlining the distribution system, simply because they are "market-oriented" companies which recognize the importance of low distribution costs. Even in Unilever, Lord Cole recalled the bad old days when distribution was looked upon as the least important of costs. The process of distribution will gradually be made less labor-intensive; the difficulty of finding additional labor, apart from its cost, is the major factor behind.

单选题Global energy demand is expected to triple by mid-century. The earth is unlikely to run out of fossil fuels by then, given its vast reserves of coal, but it seems unthinkable that we will continue to use them as we do now. It's not just a question of supply and price, or even of the disease caused by filthy air. The terrorist assault on the World Trade Center raises other scary scenarios: how much easier would it be to crack open the Trans-Alaska pipeline and how much deadlier would it be to bomb a nuclear plant than to attack a wind arm? Skeptics may recall the burst of enthusiasm for conservation and renewable power when oil prices quadrupled in the 1970s. State-funded energy research and development surged, while tax incentives boosted solar, wind and other alternatives to petroleum and the atom. But when oil supplies loosened and prices dropped in the early 1990s, governments lost interest. In the state of California, subsidies evaporated, pushing wind companies into bankruptcy. Clean energy has long way to go. Only 2.2% of the world's energy comes from "new" renewables such as small hydroelectric dams, wind, solar and geothermal. How to boost that share--and at what pace--is debated in industrialized nations--from Japan, which imports 99.7 % of its oil, to Germany, where the nearby Chernobyl accident turned the public against nuclear plants, to the U.S., where the Bush Administration has strong ties to the oil industry. But the momentum toward clean renewables is undeniable. How soon we reach an era of clean, inexhaustible energy depends on technology. Solar and wind energies are intermittent: When the sky is cloudy or the breeze dies down, fossil fuel or nuclear plants must kick into compensate. But scientists are working on better ways to store electricity from renewable sources. While developed nations debate how to fuel their power plants, however, some 1.6 billion people--a quarter of the globe's population--have no access to electricity or gasoline. Many spend their days collecting firewood and cow dung, burning it in primitive stoves that belch smoke into their lungs. To emerge from poverty, they need modern energy. And renewables can help. From village-scale hydropower to household photovoltaic systems to bio-gas stoves that convert dung into fuel. Ultimately, the earth can meet its energy needs without fouling the environment. "But it won't happen," asserts Thomas Johansson, an energy adviser to the United Nations Development Program, "without political will." To begin with, widespread government subsidies for fossil fuels and nuclear energy must be dismantled to level the playing field for renewables. Moreover, government should pressure utility to meet targets for renewable sources of energy.

单选题On a four-day trip to Ethiopia,I had a dream. In my dream, I saw two men, one older and one younger, facing one another against a background of temples and pyramids. The father was speaking as he performed the oil ceremony for his son. I became excited in the possibility of performing a visiting ceremony (31) my son in Africa. For the next six days I privately wondered what (32) to use in such a ceremony. Gradually the words (33) me. By the time we arrived in Cairo, I was ready. I told my son that there was a ceremony I wanted to (34) him in the tombs in Egypt. His eyes shone with (35) . But I wondered if he would still be receptive after my next statement. In the dream I remembered that the son was oiled, as it (36) , with a dry substance. I took this to mean that powder (37) oil was used. But what powder? I ruled out ground grass and flowers, and finally settled on sand. Sand represents the Sahara, and sand also (38) the remains of the ancient people of Egypt. That made philosophical (39) to me, but in the real world, young adults or almost anybody for that matter, (40) disinclined to have sand poured on their hair.

单选题In the United States, it is important to be on time, or punctual, for an appointment, a class, a meeting, etc. However, this may not be true in all countries. An American professor discovered this difference while teaching a class in a Brazilian university. The two-hour class was scheduled to begin at 10 a.m. and end at 12. On the first day, when the professor arrived on time, no one was in the classroom. Many students came after 10 a.m. Several arrived after 10:30 a.m. Two students came after 11 a.m. Although all the students greeted the professor as they arrived, few apologized for their lateness. Were these students being rude? He decided to study the students" behavior. The professor talked to American and Brazilian students about lateness in both an informal and a formal situation: at a lunch with a friend and in university calls, respectively. He gave them an example and asked them how they would react. If they had a lunch appointment with a friend, the average American student showed clearly lateness as 19 minutes after the agreed time. On the other hand, the average Brazilian student would be 33 minutes late. In an American university, students are expected to arrive at the appointed hour. In contrast, in Brazil, neither the teacher nor the students always arrive at the appointed hour. Classes not only begin at the scheduled time in the United States, but also end at the scheduled time. In the Brazilian class, only a few students left the class at 12:00; many remained past 12:30 to discuss the class and ask more questions. Arriving late may not be very important in Brazil, neither is staying late.
