单选题5 Tests conducted at the University of Pennsylvania's Psychological Laboratory showed that anger is one of the most difficult emotions to detect from facial expression. Professor Dallas E. Buzby confronted 716 students with pictures of extremely angry persons and asked them to identify the emotion from facial expression. Only 2 percent made correct judgments. Anger was most frequently judged as "pleased. " And a typical reaction of a student with the picture of a man who was hopping mad was to classify his expression as either "bewildered", "quizzical", or simply "amazed" . Other students showed that it is extremely difficult to tell whether a man is angry or not just by looking at his face. The in vestigators found further that women are better at detecting anger from facial expression than men are. Paradoxically, they found that psychological training does not sharpen one's ability to judge a man's emotions by his expressions but appears actually to hinder it. For in the university tests, the more courses the subjects had taken in psychology, the poorer judgment scores he turned in.

单选题 Crippling health care bills, long emergency-room waits and the inability to find a primary care physician just scratch the surface of the problems that patients face daily. Primary care should be the backbone of any health care system. Countries with appropriate primary care resources score highly when it comes to health outcomes and cost. The US takes the opposite approach by emphasizing the specialist rather than the primary care physician. A recent study analyzed the providers who treat Medicare beneficiaries.The startling finding was that the average Medicare patient saw a total of seven doctors—two primary care physicians and five specialists—in given one year. Contrary to a popular belief, the more physicians taking care of you doesn't guarantee better care. Actually, increasing fragmentation of care results in a corresponding rise in cost and medical errors. How did we let primary care slip so far? The key is how doctors are paid. Most physicians are paid whenever they perform a medical service. The more a physician does, regardless of quality or outcome, the better he's reimbursed. Moreover, the amount a physician receive leans heavily toward medical or surgical procedures. A specialist who performs a procedure in a 30-minute visit can be paid three times more than a primary care physician using that same 30 minutes to discuss a patient's disease.Combine this fact with annual government threats to indiscriminately cut reimbursements, physicians are faced with no choice but to increase quantity to boost income. Primary care physicians who refuse to compromise quality are either driven out of business or to each-only practices, further contributing to the decline of primary care. Medical students aren't blind to this scenario. They see how heavily the reimbursement deck is stacked against primary care. How do we fix this problem? It starts with reforming the physician reimbursement system. Remove the pressure for primary care physicians to squeeze in more patients per hour, and reward them for optimally managing their diseases and practicing evidence based medicine. Make primary care more attractive to medical students by forgiving student loans for those who choose primary care as a career and reconciling the marked difference between specialist and primary care physician salaries.

单选题 Could the bad old days of economic decline be about to return? Since OPEC agreed to supply-cuts in March, the price of crude oil has jumped to almost $26 a barrel, up from less than$10 last December. Tbis near-tripling of oil prices calls up scary memories of the 1973 oil shock, when prices quadrupled, and 1979-1980, when they also almost tripled. Both previous shocks resulted in double-digit inflation and global economic decline. So where are the headlines warning of gloom and doom this time? The oil price was given another push up this week when Iraq suspended oil exports. Strengthening economic growth, at the same time as winter grips the northern hemisphere, could push the price higher still in the short term. Yet there are good reasons to expect the economic consequences now to be less severe than in the 1970s. In most countries the cost of crude oil now accounts for a smaller share of the price of petrol than it did in the 1970s. In Europe, taxes account for up to four-fifths of the retail price, so even quite big changes in the price of crude have a more muted effect on pump prices than in the past. Rich economies are also less dependent on oil than they were, and so less sensitive to swings in the oil price. Energy conservation, a shift to other fuels and a decline in the importance of heavy, energy-intensive industries have reduced oil consumption. Software, consultancy and mobile telephones use far less oil than steel or car production. For each dollar of GDP ( in constant prices) rich economies now use nearly 50% less oil than in 1973. The OECD estimates in its latest Economic Outlook that, if oil prices averaged $22 a barrel for a full year, compared with $13 in 1998, this would increase the oil import bill in rich economies by only 0.25% ~ 0.5% of GDP. That is less than one-quarter of the income loss in 1974 or 1980. On the other hand, oil-importing emerging economies—to which heavy industry has shifted—have become more energy-intensive, and so could be more seriously squeezed. One more reason not to lose sleep over the rise in oil prices is that, unlike the rises in the 1970s, it has not occurred against the background of general commodity-price inflation and global excess demand. A sizable port/on of the world is only just emerging from economic decline. The Economist's commodity price index is broadly unchanging from a year ago. In 1973 commodity prices jumped by 70% , and in 1979 by almost 30%.

单选题When most people think about changing their body shape, they usually focus on just losing weight. Books and magazines about dieting are among the most popular in the world. Dieting is an important part of staying fit and healthy, but losing weight by means of dieting takes time; losing weight too fast can cause great health problems. Dieting means change one's eating habits to a healthier pattern, but many women mistake the concept of dieting and thinking that the less one eats, the better. As a result, they lose health as well as weight. Aerobic exercise is a moderate intensity workout that, over a certain period of time, will provide the body's use of oxygen. Nowadays, aerobic exercise has become a very trendy workout among youths. Not only is performing aerobic exercise interesting, but it is also very beneficial for health. There are different types of aerobics like jogging, swimming, kickboxing, fitness walking, inline skating, bicycling, etc. Aerobics strengthens the heart and lungs. It is also especially popular with women. But neither of these two methods, dieting and aerobics, can help shape the body. To do this, you need to build muscle. So, if a firmer and shapelier body is your goal, 60 percent of your exercise routine should involve strengthening moves, and only 30 percent should be aerobic exercises. For a proper body-shaping routine, you should plan three strength-training sessions a week with weights. Use weights which are as heavy as possible while still allowing you to do 8 to 12 reps of each exercise. Do one to three exercises for each muscle groups — for example, chest and biceps, or back, shoulders and triceps. You should combine this with fast-paced aerobics activities, like swimming, cycling, walking, running, or in-line skating. Plan three to four workouts a week, 15 to 20 minutes each, increasing the pace each week. As you build muscle, you may find that you gain weight in spite of all of your calorie-burning exercise. Don't worry. It's probably muscle, which is denser that fat. And muscle is also a calorie-burning tissue. With more muscle, you can burn more calories, even when you are not exercising. When you are trying to build muscle, you need two to three servings of protein a day, but the main part of your diet should be carbohydrates. And in order to get the energy you need for a high-intensity workout, you should eat something, especially carbohydrates, an hour or so before your workout. While weight training will firm and shape your body, it has other benefits too. It improves bone and muscle strength and burns calories, leading to improved health and a higher quality of life.

单选题The world is going through the biggest wave of mergers and acquisitions never witnessed. The process sweeps from hyperactive America to Europe and reaches the emerging countries with unsurpassed might. Many in these countries are looking at this process and worrying: "Won"t the wave of business concentration turn into an uncontrollable anti-competitive force?" There"s no question that the big are getting bigger and more powerful. Multinational corporations accounted for less than 20% of international trade in 1982. Today the figure is more than 25% and growing rapidly. International affiliates account for a fast-growing segment of production in economies that open up and welcome foreign investment. In Argentina, for instance, after the reforms of the early 1990s, multinationals went from 43% to almost 70% of the industrial production of the 200 largest firms. This phenomenon has created serious concerns over the role of smaller economic firms, of national businessmen and over the ultimate stability of the world economy. I believe that the most important forces behind the massive M&A wave are the same that underlie the globalization process: falling transportation and communication costs, lower trade and investment barriers and enlarged markets that require enlarged operations capable of meeting customer"s demands. All these are beneficial, not detrimental, to consumers. As productivity grows, the world"s wealth increases. Examples of benefits or costs of the current concentration wave are scanty. Yet it is hard to imagine that the merger of a few oil firms today could recreate the same threats to competition that were feared nearly a century ago in the U.S., when the Standard Oil trust was broken up. The mergers of telecom companies, such as WorldCom, hardly seem to bring higher prices for consumers or a reduction in the pace of technical progress. On the contrary, the price of communications is coming down fast. In cars, too, concentration is increasing—witness Daimler and Chrysler, Renault and Nissan—but it does not appear that consumers are being hurt. Yet the fact remains that the merger movement must be watched a few weeks ago, Alan Greenspan warned against the megamergers in the banking industry. Who is going to supervise, regulate and operate as lender of last resort with the gigantic banks that are being created? Won"t multinationals shift production from one place to another when a nation gets too strict about infringements to fair competition? And should one country take upon itself the role of "defending competition" on issues that affect many other nations, as in the U.S. vs. Microsoft case?

单选题{{B}}Passage Five{{/B}} In the 1970s many of us thought working outside the home would be liberating for women, freeing them from financial dependence on men and allowing them roles beyond those of wife and mother. {{U}}It hasn't worked out that way{{/U}}. Women's labor has been bought on the cheap, their working hours have become longer and their family commitments have barely diminished. The reality for most working women is a near impossible feat of working ever harder. There have been new opportunities for some women: professions once closed to them, such as law, have opened up. Women managers are commonplace, though the top boardrooms remain male preserves. Professional and managerial women have done well out of neoliberalism. Their salaries allow them to hire domestic help. But more women, such as the supermarket or call centre workers; the cooks, cleaners and hairdressers, all find themselves in low-wage, low-status jobs with no possibility of paying to have their houses cleaned by someone else. Even those in professions once-regarded as reasonably high-status, such as teaching, nursing or office work, have seen that status pushed down with longer hours, more regulation and lower pay. Women's right to work should not mean a family life where partners rarely see each other or their children. Yet a quarter of all families with dependent children have one parent working nights or evenings, many of them because of childcare problems. The legislative changes of the 1960s and 1970s helped establish women's legal and financial independence, but we have long come up against the limits of the law. A more radical social transformation would mean using the country's wealth—much of it now produced by women—to create a decent family life. A 35-hour week and a national childcare service would be a start. But it is hard to imagine the major employers conceding such demands. Every gain that women have made at work has had to be fought for. Women's lives have undergone a revolution over the past few decades that has seen married women, and mothers in particular, go from a private family role to a much more social role at work. But they haven't left the family role behind: now they are expected to work even harder to do both.

单选题Like the body, the memory improves with use. Unlike the body, the memory can improve with age. For many years, doctors have been studying the way the brain works. We all know that the brain has two sides, the left and the right. The right side controls the senses (seeing, hearing, feeling, tasting and smelling), and is the creative and imaginative side. The left side of the brain controls our logical thinking. It processes the information which comes in, and puts it into order. We call the left side the "educated" side of the brain and generally, in western societies, people have developed this side of the brain more than the right side. Scientists believe that our brain will work much more efficiently if both the right side and the left side are developed equally. In many schools today, teachers try to educate the children in such a way that both sides of the brain are used. This can be done with logical subjects including mathematics and science as well as with creative subjects such as art and literature. The result achieved by students who are educated in this way is usually better than the result of students who are educated in a more traditional way. Traditional teaching tends to exercise the left side of the brain without paying very much attention to the development of the right side. Great thinkers such as Bertand Russell the philosopher, and Albert Einstein, the scientist, only in their work, but also in creative and imaginative activities. It was because of their many different interests in life that they were able to achieve the full development of both sides of their brain. As long as Einstein and Russell lived, their brains functioned efficiently. It was their bodies, finally, which could not go on any longer.
