单选题Copying Birds May Save Aircraft Fuel Both Boeing and Airbus have trumpeted the efficiency of their newest aircraft, the 787 and A350 respectively. Their clever designs and lightweight composites certainly make a difference. But a group of researchers at Stanford University, led by Ilan Kroo, has suggested that airlines could take a more naturalistic approach to cutting jet-fuel use, and it would not require them to buy new aircraft. The answer, says Dr Kroo, lies with birds. Since 1914, and a seminal paper by a German researcher called Carl Wieselsberger, scientists have known that birds flying in formation—a V-shape, echelon or otherwise—expend less energy. The air flowing over a bird"s wings curls upwards behind the wingtips, a phenomenon known as upwash. Other birds flying in the upwash experience reduced drag, and spend less energy propelling themselves. Peter Lissaman, an aeronautics expert who was formerly at Caltech and the University of Southern California, has suggested that a formation of 25 birds might enjoy a range increase of 71%. When applied to aircraft, the principles are not substantially different. Dr Kroo and his team modeled what would happen if three passenger jets departing from Los Angeles, San Francisco and Las Vegas were to rendezvous over Utah, assume an inverted V-formation, occasionally swap places so all could have a turn in the most favorable positions, and proceed to London. They found that the aircraft consumed as much as 15% less fuel (coupled with a reduction in carbon-dioxide output). Nitrogen-oxide emissions during the cruising portions of the flight fell by around a quarter. There are, of course, kinks to be worked out. One consideration is safety, or at least the perception of it. Would passengers feel comfortable traveling in convoy? Dr Kroo points out that the aircraft could be separated by several nautical miles, and would not be in the intimate groupings favored by display teams like the Red Arrows. A passenger peering out of the window might not even see the other planes. Whether the separation distances involved would satisfy air-traffic-control regulations is another matter, although a working group at the International Civil Aviation Organization has included the possibility of formation flying in a blueprint for new operational guidelines. It remains to be seen how weather conditions affect the air flows that make formation flight more efficient. In zones of increased turbulence, the planes" wakes will decay more quickly and the effect will diminish. Dr Kroo says this is one of the areas his team will investigate further. It might also be hard for airlines to co-ordinate the departure times and destinations of passenger aircraft in a way that would allow them to gain from formation flight. Cargo aircraft, in contrast, might be easier to reschedule, as might routine military flights. As it happens, America"s armed forces are on the case already. Earlier this year the country"s Defense Advanced Research Projects Agency announced plans to pay Boeing to investigate formation flight, though the program has yet to begin. There are reports that some military aircraft flew in formation when they were low on fuel during the Second World War, but Dr Lissaman says they are apocryphal. "My father was an RAF pilot and my cousin the skipper of a Lancaster lost over Berlin," he adds. So he should know.

单选题Most people seek some degree of inner peace at work, and it can be difficult to obtain. Work is stressful, and most of us tend to either overwork ourselves or we are, for other reasons, negatively affected by things happening at work. The struggle to maintain one's inner peace and avoid burnout(职业倦怠症)has become a standard ingredient, of modern working life. Many of us attend seminars on work life-balance, we see therapists, we meditate, or we seek advice on how to handle stressful careers. The balancing of one's personal life and work life is a challenge to all of us who aspire to be successful—by whatever relevant metric. It is not surprising that so much is being said and written on the topic. Unfortunately, I have noticed a tendency to talk about the dangers of burnout at work in terms that provoke fear and panic in the stressed individual rather than lead him or her to slow down. Our methods of discussing the dangers of stress and burnout are too defensive and too reactive. We tend to think that the busyness of work is somehow dangerous, and that we need to balance out the busyness with the emptiness of non-work. Our emphasis on practices such as meditation, yoga, mindfulness—or simply just periods of nothingness—as means of balancing out the stress of work illustrates this point. All of these things can be good and helpful in their own right, but they all stand for a "letting go" of things. They are defined by inactivity. This logic leads to a kind of life where the "active" is considered to be dangerous and something that should always be balanced out by the "inactive". We oscillate between the two extremes—fearful of staying too long in any of the camps. This oscillation is stressful in itself. It would be much better if we had a way of living that could embrace, enjoy, and handle the tough, everyday work life rather than constantly looking for ways to escape it.

单选题{{B}}Passage Four{{/B}} Social change is more likely to occur in societies where there is a mixture of different kinds of people than in societies where people are similar in many ways. The simple reason for this is that there are more different ways of looking at things present in the first kind of society. There are more ideas, more disagreements in interest, and more groups and organizations with different beliefs. In addition, there is usually a greater worldly interest and greater tolerance in mixed societies. All these factors tend to promote social change by opening more as of life to decision. In a society where people are quite similar in many ways, there are fewer occasions for people to see the need or the opportunity for change because everything seems to be the same. And although conditions may not be satisfactory, they are at least customary and undisputed. Within a society, social change is also likely to occur more frequently and more readily in the material aspects of the culture than in the non-material, for example, in technology rather than in values; in what has been learned later in life rather than what was learned early; in the less basic and less emotional aspects of society than in their opposite; in the simple elements rather than in the complex ones; in form rather than in substance; and in elements that are acceptable to the culture rather than in strange elements. Furthermore, social change is easier if it is gradual. For example, it comes more readily in human relations on a continuous scale rather than one with violent changes. This is one reason why change has not come more quickly to Black Americans as compared to other American minorities, because of the sharp difference in appearance between them and their white counterparts.

单选题With the increasing pace of economic globalization and competition among various countries in the market, information, technology, professionals, capital and other types of economic resources is becoming increasingly evident. International (1) is becoming progressively (2) . Previously (3) competition among enterprises in different countries is growing gradually into competition among governments that finds expression in a concentrated form. Previous (4) contention for enterprises' interests in the world market now evidences itself in the contention for (5) interests. In this new situation, to (6) national interests and to enable a country to be constantly in a favorable position in the international market, the most important thing is to have a highly (7) government that (8) the full trust of citizens. The basic objective of the study of the "government administration" is to (9) the competitive edge of a government in the international market, to (10) the efficiency and quality of government administrative behaviors, and to enhance the skills and the efficiency of government policy operations. The evident (11) between government administration and enterprise management lies in the fact (12) the former is a macro-activity and represents the overall national interests. Considering this from the (13) of the theory of behavioral efficiency function, the degree of the efficiency and quality of government administrative behaviors and the standard of the skills and the efficiency of government policy operations have a direct (14) on the amount of national interests and the degree of security and happiness of its people. Thus, to (15) the level of overall national interests requires a highly efficient enterprise management and a high-quality enterprise group with significant core competitiveness. More importantly, it requires highly efficient government administration and the government's international competitiveness to have a (16) advantage. For China, a country that is still in the (17) of "shift in the mode of growth" and "transformation in the system", the fundamental (18) to turn this objective into a (19) is to make innovations in government administration. So, against the (20) backgrounds of economic globalization and the domestic economic transformation, how should we make innovations in government administration? I think many things can be done in this regard. Yet the most important thing is to effect the change of the concept, functions, forms and the institution of government administration.
