单选题But inthe end he approved of our proposal.

单选题Appealing to these expectations, Obama told Americans what they want to hear. People with insurance won't be required to change plans or doctors; they'll enjoy more security because insurance companies won't be permitted to deny coverage based on "pre - existing conditions" or cancel policies when people get sick. All Americans will be required to have insurance, but those who can't afford it will get subsidies. As for costs, not to worry. "Reducing the waste and inefficiency in Medicare and Medicaid will pay for most of is plan. " Obama said. He pledged to" not sign a plan that adds one dime to our [budget] deficits- either now or in the future. "If you believe Obama, what's not to like? Universal insurance. Continued choice. Lower costs. The problem is that you can't entirely believe Obama. If he were candid - if we were candid - we'd all acknowledge that the goals of our ideal health - care system collide. Perhaps we can have any two, but not all three. If we want universal insurance and unlimited patient and doctor choice, costs will continually spiral upward, because there will be no reason or no one to stop them. We have a variant of that today -a cost -plus system, with widespread insurance and open -ended reimbursement. Higher costs push up premiums and taxes. That's one reason health spending has gone from 5 percent of gross domestic product in 1960 to 16 percent in 2007. (Other reasons: new technologies, rising incomes. ) But controlling spending requires limits on patients and doctors. What is the author's attitude towards Obama's reform plan on health- care?A.

单选题American Sports The United States is a sports-loving nation. Sports in America take a variety of forms: organized competitive struggles, which draw huge crowds to cheer their favorite team to victory; athletic games, played for recreation anywhere sufficient space is found; and hunting and fishing. Most sports are seasonal, so that what is happening in sports depends upon the time of year. Some sports are called spectator sports, as the number of spectators great exceeds the number playing in the game. Baseball is the most popular sport in the US. It is played throughout the spring and summer, and professional baseball teams play well into the fall. Although no other game is exactly like baseball, perhaps the one most nearly like it is the English game other game of cricket. Football is the most popular sport in the fall. The game originated as a college sport more than 75 years ago. It is still played by almost every college and .university in the country, and the football stadiums of some of the largest universities seat as many as 80, 000 people. The-game is not the same as European football or soccer. In American football there are 11 players on each team, and they are dressed in padded uniforms and helmets because the game is rough and injuries are likely to occur. Basketball is the writer sport in American schools and colleges. Like football, basketball originated in the US and is not popular in other countries. Many Americans prefer it to football because it is played indoors throughout the winter and because it is a faster game. It is a very popular game with high schools, and in more than 20 states, state-wide high school matches are held yearly. Other spectator sports include wrestling, boxing; and horse racing. Although horse-racing fans call themselves sportsmen, the accuracy of term is questionable, as only the jockeys who ride the horses in the races can be considered athletes. The so-called sportsmen are the spectators, who do not "assemble" primarily to see the horse race, but to bet upon the outcome of each race. Gambling is the attraction of horse racing.

单选题Look After Your Voice Often speakers at a meeting experience dry mouths and ask for a glass of water. You can solve the problem by activating the saliva in you mouth. First gently bite the edges of your tongue with your teeth. Or press your entire tongue to the bottom of your mouth and hold it there until the saliva flow. Or you can imagine that you are slicing a big juicy lemon and sucking the juice. Before you begin your talk, be kind to your voice. Avoid milk or creamy drinks which coat your throat. Keep your throat wet by drinking a little sweetened warm tea or diluted fruit juice. If you sense that your are losing your voice, stop talking completely. Save your voice for your speech. You may feel foolish using paper to write notes, but the best thing you can do is to rest your voice. If you need to see a doctor, perhaps you can get some advice from a professional singer. In the meantime, do not even talk in a low voice. What about drinking alcohol to wet your throat? I advice you not to touch alcohol before speaking. The problem with alcohol is that one drink gives you a little confidence. The second drink gives you even more confidence. Finally you will feel all-powerful and you will feel you can do everything, but in fact your brain and your mouth do not work together properly. Save the alcohol until after you finish speaking. Perhaps you want to accept the advice, but you may wonder if you can ever change the habits of a lifetime. Of course you can. Goethe, who lived before indoor skating rinks or swimming pools, said, "We learn to skate in the summer and swim in the winter. "Take this message to heart and give yourself time to develop your new habits. If you are willing to change, you will soon be able to say that you will never forget these techniques because they became a part of your body.

单选题Supermarket Most supermarkets need a very large floor area, sometimes at least ten times as big as that of an ordinary shop. There are usually two doors, one as an entrance and the other as an exit. The rest of the side facing the street is largely of plate glass, with goods or advertising material displayed. The other three wails are normally decorated in light colours, giving an impression of cleanliness (清洁)and brightness. Most supermarkets are on one floor only. Goods being stored in rooms at the back or upstairs. At right-angles to the window stretch long structures about six feet high with a number of shelves on each side. Similar shelf units or frozen food containers extend round the walls. Broad aisles(通道)between the shelf units and ample(足够的)space between them and the window and also the far wall allow room for the circulation of many people. Individual commodities(商品), in tins, bags, boxes or other containers, are stacked (堆放) in groups on the shelves, and each group is labelled with a price ticket. Metal baskets near the entrance are taken by the shoppers who collect in them the goods they select from the shelves. Between the shelf units and the window in one half of the shops are a number of small counters about three feet high. Beside each sits a cashier (现金出纳员), who operates a machine for reckoning, detailing the cost of each customer's purchases. The customer places the basket at one end of the counter so that it can be emptied by the cashier who records the price of the commodities one by one, before putting each on a moving section of the counter top. The goods are collected and packed into the customer's bag by another assistant at the end of the counter. The cashier finally hands a printed slip recording all prices to the customer, who pays the total, collects the bag and leaves.

单选题World Crude Oil Production May Peak a Decade Earlier Than Some Predict In a finding that may speed efforts to conserve oil, scientists in Kuwait predict that world conventional crude oil production will peak in 2014. This prediction is almost a decade earlier than some other predictions. Their study is in ACS" Energy a related concept is that of Peak Oil. The term "Peak Oil" indicates the moment in which worldwide production will peak, afterwards to start on irreversible decline. The Hubbert model accurately predicted that oil production would peak in the United States in 1970. The model has since gained in popularity and has been used to forecast oil production worldwide. However, recent studies show that the model is insufficient to account for more complex oil production cycles of some countries. Those cycles can be heavily influenced by technology changes, politics, and other factors, the scientists say. The new study describes development of a new version of the Hubbert model that provides a more realistic and accurate oil production forecast. Using the new model, the scientists evaluated the oil production trends of 47 major oil-producing countries, which supply most of the world"s conventional crude oil. They estimated that worldwide conventional crude oil production will peak in 2014, years earlier than anticipated. The scientists also showed that the world"s oil reserves are being reduced at a rate of 2.1 percent a year. The new model could help inform energy-related decisions and public policy debate, they suggest.

单选题{{B}}第三篇{{/B}} {{B}} International Sports{{/B}} Some people believe that international sport creates goodwill between the nations and that if countries play games together they will learn to live together. Others say that the opposite is true: that international contests encourage false national pride and lead to misunderstanding and hatred. There is probably some truth in both arguments, but in recent years the Olympic Games have done little to support the view that sports encourages international brotherhood. Not only was there the tragic incident involving the murder of athletes, but the Games were also ruined by lesser incidents caused principally by minor national contests. One country received its second-place medals with visible indignation after the hockey (曲棍球) final. There had been noisy scenes at the end of the hockey match, the loser's objection to the final decisions. They were convinced that one of their goals should not have been disallowed and that their opponents' victory was unfair. Their manager was in a rage when he said: "This wasn't hockey. Hockey and the International Hockey Federation are finished." The president of the Federation said later that such behavior could result in the suspension of the team for at least three years. The American basketball team announced that they would not yield first place to Russia, after a disputable end to their contest. The game had ended in disturbance. It was thought at first that the United States had won, by a single point, but it was announced that there were three seconds still to play. A Russian player popped it into the basket. It was the first time the USA had ever lost an Olympic basketball match. An appeal jury debated the matter for four and a half hours before announcing that the result would stand. The American players then voted not to receive the silver medals. Incidents of this kind will continue as long as sport is played competitively rather than for the love of the game. The suggestion that athletes should compete as individuals, or in nonnational teams, might be too much to hope for. But in the present organization of the Olympics there is far too much that encourages aggressive patriotism.

单选题Smoking Can Increase Depressive Symptoms in Teens While some teenagers may puff on cigarettes to "self-medicate" (自我治疗) against the blues (忧郁), scientists at the University of Toronto and the University of Montreal have found that smoking may actually 1 depressive symptoms in some teens. "This observational study is one of the few to examine the perceived 2 benefits of smoking among teens," says lead researcher Michael Chariton, a research associate at the Ontario Tobacco Research Unit of the University of Toronto. " 3 cigarettes may appear to have self-medicating effects or to improve mood, in the long 4 we found that teens who started to smoke reported higher depressive symptoms. " As part of the study, some 662 high school teenagers completed up to 20 questionnaires about their use of cigarettes to 5 mood. Secondary schools were selected to provide a mix of French and English participants, urban and rural schools, and schools 6 in high, moderate and low socioeconomic neighborhoods. Participants were divided into three 7 : never smokers; smokers who did not use cigarettes to self-medicate improve mood or physical 8 ; smokers who used cigarettes to self-medicate. Depressive symptoms were measured using a scale that asked how often participants felt too tired to do things; had 9 going to sleep or staying asleep; felt unhappy, sad, or depressed; felt hopeless about the future; felt anxious or tense; and worried too much about things. "Smokers who used cigarettes as mood 10 had higher risks of elevated (提升) depressive symptoms 11 teens who had never smoked," says co-researcher Jennifer O"Loughlin, a professor at the University of Montreal Department of Social and Preventive Medicine. "Our study found that teen smokers who reported emotional benefits from smoking are 12 higher risk of depressive symptoms." The 13 between depression and smoking exits 14 among that use cigarettes to feel better. " It"s 15 to emphasize that depressive symptom scores were higher among teenagers who reported emotional benefits from smoking after they began to smoke," says Dr. Chariton.
