单选题The Smog For over a month, Indonesia was in crisis. Forest fires raged out of control as the country suffered its worst drought for 50 years. Smoke from the fires mixed with sunlight and hot dry air to form a cloud of smog. This pollution quickly spread and within days it was hanging over neighboring countries including Malaysia, Singapore and Thailand. When the smoke combined with pollution from factories and cars, it soon became poisonous. Dangerous amounts of CO became trapped under the smog and pollution levels rose. People wheezed (喘息) and coughed as they left the house and their eyes watered immediately. The smog made it impossible to see across streets and whole cities disappeared as grey soot (烟灰) covered everything. In some areas, water was hosed (用胶管浇) from high-rise city buildings to try and break up the smog. Finally, heavy rains, which came in November. Put out the fires and clear the air. But the environmental costs and health problems will remain. Many people from South-Eastern Asian cities already suffer from breathing huge amounts of car exhaust fumes and factory pollution Breathing problems could well increase and many non-sufferers may have difficulties for the first time. Wildlife has suffered too. In lowland forests, elephants, deer, and tigers have been driven out of their homes by smog. But smog is not just an Asian problem. In fact .was world was first used in London in 1905 to describe the mixture of smoke and thick fog. Fog often hung over the capital. Sometimes the smog was so thick and poisonous that people were killed by breathing problems or in accidents. About 4,000 Londoners died within five days as a result of thick smog in 1952.

单选题{{B}}第三篇{{/B}} Babies' Response For some time in the past it has been widely accepted that babies, and other creatures learn to do things because certain acts lead to "rewards": and there is no reason to doubt that this is true. But it also used to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological(生理的) "drives" as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise. It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome. Papousek began his studies by using milk in the normal way to "reward" the babies and so teach them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children's responses in situations where no milk was provided. He quickly found that children as young as four months old would learn to turn their heads to right or left if the movement "switched on" a display of lights, and indeed that they were capable of learning quite complex turns to bring about this result, for instance, two left or two right, or even to make three turns to one side. Papousek's light display was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the lights close, although they would "smile and bubble" when the display came on. Papousek concluded that it was not primarily the sight of the lights that pleased them, it was the success they were achieving in solving the problem, in mastering the skill, and that there existed a fundamental human urge to make sense of the world and brought it under intentional control.

单选题American Firms The annual review of American company board practices by Korn/Ferry, a firm of headhunters, is a useful indicator of the health of corporate governance. This year's review, published on November 12th, shows that the Sarbanes-Oxley Act, passed in 2002 to try to prevent a repeat of corporate collapses such as Enron's and WorldCom's, has had an impact on the boardroom—albeit at an average implementation cost that Korn/Ferry estimates at $5.1 m per firm. Two years ago, only 41% of American firms said they regularly held meetings of directors without their chief executive present; this year the figure was 93%. But some things have been surprisingly unaffected by the backlash against corporate scandals. For example, despite a growing feeling that former chief executives should not sit on their company's board, the percentage of American firms where they do has actually edged up, from 23% in 2003 to 25% in 2004. Also, disappointingly few firms have split the jobs of chairman and chief executive. Another survey of American boards published this week, by A.T. Kearney, a firm of consultants, found that in 2002 14% of the boards of S&P 500 firms had separated the roles, and a further 16% said they planned to do so. But by 2004 only 23% overall had taken the plunge. A survey earlier in the year by consultants at McKinsey found that 70% of American directors and investors supported the idea of splitting the jobs, which is standard practice in Europe. Another disappointment is the slow progress in abolishing "staggered" boards—ones where only one-third of the directors are up for re-election each year, to three-year terms. Invented as a defence against takeover, such boards, according to a new Harvard Law School study by Lucian Bebchuk and Alma Cohen, are unambiguously "associated with an economically significant reduction in firm value". Despite this, the percentage of S&P 500 firms with staggered boards has fallen only slightly—from 63% in 2001 to 60% in 2003, according to the Investor Responsibility Research Centre. And many of those firms that have been forced by shareholders to abolish the system are doing so only slowly. Merck, a pharmaceutical company in trouble over the possible side-effects of its arthritis drug Vioxx, is allowing its directors to run their full term before introducing a system in which they are all re-elected (or otherwise) annually. Other companies' staggered boards are entrenched in their corporate charters, which cannot be amended by a shareholders' vote. Anyone who expected the scandals of 2001 to bring about rapid change in the balance of power between managers and owners was, at best, naive.

单选题{{B}}第二篇{{/B}} Good Table Manners Manners play an important part in making a favorable impression at the dinner table. Here are some general rules: Napkin (餐巾) use The meal begins when the host unfolds his or her napkin. This is your signal to do the same, so place your napkin on your lap. Unfold it completely if it is a small napkin, or in half, lengthwise (纵向地), if it is a large dinner napkin. If you need to leave the table during the meal, place your napkin on your chair as a signal to your server that you will be returning. Once the meal is over, place your napkin neatly on the table to the right of your dinner plate. Do not refold it. Use a napkin only for your mouth. Never use it for your nose, face or forehead. Use of utensils (餐具) Start with the knife, fork or spoon furthest from your plate, and work your way in, using one utensil for each course. If soup is served, remember to spoon away from yourself. This helps stop the drips. Do not put the entire soup spoon in your mouth. Instead, fill a soup spoon about 75 per cent with soup, and sip (啜饮) it from the side noiselessly. After finishing dinner, place the knife and fork parallel to one another across the Plate with the knife alade facing inward toward the plate. Using your f'ingers Here's a list of finger foods: sandwiches, cookies, small fruits or berries with stems, French fries and potato chips, hamburgers. Chew(咀嚼) with your mouth closed and don't make noise; don't talk with your mouth full. Bread must be broken with your hands. It is never cut with a knife. Don't pick something out of your teeth. Instead, excuse yourself to the bathroom. If possible, try not to cough at the table. Do not put your elbows(肘) on the table. In France, it is essential to have both hands above the table at the same time. Do not put bones or anything else on the table. Things that are not eaten should be put on your plate.
