| 第1题：{{B}}Passage Four{{/B}} Joann says. "Even though we are scattered across the country, we can share thoughts, opinions and concerns about issues that affect us. It’s like a big family. When Mayer and I travel around the country, we make it a point to look up other Senior-Net members." Mary Furlong, founder of the 10-years-old network, says it is a painless way to socialize, especially for those recently widowed and reluctant to go out alone, and for the disableD、Senior-Net has more then 6 000 members across the United States. Joann Oakes and Mayer Solen fell for each other just beforeChristmas in 1991. She had been watching from a distance as Mr. Solen flitted from one group of friends to another. Finally, the two began a conversation. They discovered they were both widoweD、They talked on and on.At midnight, they said good night, turned off their computers and went to bed, Mr. Solen in the south-western state of Nevada, and Mrs. Oakes in the north-western state of Washington. From then on they talked nearly every day via their computers until their marriage. Computers are playingCupid for what seems to be an unlikely target—a generation that didn’t know the difference between a mouse and a modem until they reached 60. Now, older adults are plugged in to exchange gardening tips, debate religion ,or try to recall the lines of old time popular songs. The marriage between seniors and computers is, in fact, perfectly natural. They grew up in a time when people wrote weekly letters to each other and kept journals and diaries.A、computer is an easier way to do the same. With no risk of censure or rejection, grandfathers can let their hair down.Church-going people confess they are not really sure what they think about religion. People who always thought of themselves as conserved and "respectable" may be found flirting shamelessly with correspondents who live 500 miles away. If anyone dislikes the company or the discussion, they don’t have to be polite. "Just hit the control button and you’re gone," says Joann Oakes. |
| 第2题：The heart bypass (心脏搭桥术)has become part of our cultural life. It has come to seem like a ceremony of passage for the successful male, a red symbol of courage in midlife. Six hundred thousand bypass operations are performed a year in the United States.After a bypass, most heart patients experience significant relief from the peculiar discomfort in the chest caused by insufficient blood to the heart muscle. In some cases the surgery can dramatically extend life.American heart patients, who now number about 12 million, are enthusiastic about the surgery.Bypass is one of the most common major operations inAmeric A、 In private, however, many of my fellow workers in medicine suspect that bypass has become too popular. A、recent Harvard study showed that as many as two-thirds of patients referred for bypass don’t need it or could have it postponeD、InCanada andBritain, where physicians perform bypass surgery much less frequently than they do inAmerica,heart patients fare just as well. In addition, bypassing a blocked section of an artery does nothing to ;prevent the artery (动脉) from getting clogged somewhere else. In fact, bypass surgery can accelerate the development of new blockage. But bypass did not have to prove itself. It has become hugely popular. Voices of caution were drowned out as more and more hospitals raced to offer bypass.By 1979,100 000: bypasses a year were taking place, and 10 years later the figure has risen to 260 000. Medical students were keen to train in cardiac (心脏的) surgery; for all the hard training, it was a advancing ,challenging fielD、In fact, the rewards are handsome. There is more money to be made performing this surgery than there is in practicing in almost any other field of medicine. The idea of bold surgeons reaching into our bodies to save a wounded heart cannot but exert a powerful grip on our imaginations, as if we are witnessing a cultural ceremony where two overachieving individuals—surgeon and patient—come together,Bypass may indeed be both a life-extending and pain-relieving procedure for many patients.But perhaps it has transfixed us for too long. In the last paragraph the author implies that ______. A、the popularity of bypass operation has its profound financial reasons B、doing bypass operation makes a doctor famous C．we shouldn’t have blind faith in anything even if it is good D．receiving a bypass operation makes a person satisfied |

| 第5题：{{B}}Passage Two{{/B}} One way for the body to get enough oxygen to its tissues when breathing oxygen-poor air is for it to make more red blood cells. This increases the amount of hemoglobin(血红蛋白), the protein that carries oxygen.Although less haemoglobin in the arteries is saturated with oxygen at high altitudes, having more of it makes up for the shortfall. People native to the highAndes are known to have more red blood cells than lowlanders, and athletes who train at altitude can increase their concentration of cells. But while many Tibetans also live at high altitudes, they do not have significantly elevated levels of haemoglobin. Instead they seem to boost the amount of nitric oxide, which dilates(使膨胀) blood vessels and increases blood flow. NowCynthiaBeall, an anthropologist fromCase Western Reserve University inCleveland, Ohio, has found a third kind of adaptation. When she tested the blood of 236 people in theAmbaras region in the Semien Mountains ofEthiopia, she found that 95 percent of the haemoglobin in their arteries is saturated with oxygen, almost as much as that of people living at low altitudes and roughly 5 per cent above that of residents in theAndes or Tibet. "That shouldn’t be, "saysBeall. They must have a massively efficient way to get oxygen from the lungs to the blood, she says.But just what remains mysterious. They do not have higher concentrations of haemoglobin than anyone else, nor do they have a different kind of haemoglobin. Beall adds that this ability might be found in all people living in that part of the world, and not just those in the study. It might be why so many world-class endurance athletes areEthiopian. "The next study needs to look at that,"she says. |
