单选题 Crystal Ear One day a friend asked my wife Jill if I wanted a hearing aid. "He certainly does," replied Jill. After hearing about a remarkable new product, Jill finally got up me nerve to ask me if I'd ever thought about getting a heating aid. "No way." I said. "It would make me look 20 years older." "No, no," she replied. "This is entirely different. It's Crystal Ear!" Jill was tight. Crystal Ear is different—not the old-styled body worn or over—the—ear aid, but an advanced personal sound system so small that it's like contacts (隐形眼镜) for your ears. And Crystal Ear is super sensitive and powerful, too. You will hear sounds your ears have been missing for years. Crystal Ear will make speech louder, and the sound is pure and natural. I couldn't believe how tiny it is. It is smaller than the tip of my little finger and it's almost invisible when worn. There are no wires, no behind-the-ear device. Put it in your ear and its ready-to wear mold (形状) fits comfortably. Since it's not too loud or too fight, you may even forget that you're wearing it! Use it at work or at play. And if your hearing problem is worse in certain situations, use Crystal Ear only when you need it. Hearing loss, which occurs typically prior to teenage years, progresses throughout one's life time. Although hearing loss is now the world's number one health problem, nearly 90 percent of people suffering hearing loss choose to leave the problem untreated. For many millions, treating hearing loss in a conventional way can involve numerous office visits, expensive testing and adjustments to fit your ear. Thanks to Crystal Ear, the "sound solution" is now convenient. Almost 90 percent of people with mild hearing loss, and millions more with just a little hearing drop-off, can be dramatically helped with Crystal Ear. Moreover, its superior design is energy-efficient, so batteries can last months. Crystal Ear is now available to help these people treat their hearing loss with a small heating amplifier(放大器).

Why are many finding it increasingly difficult to start and sustain intimate relationships? Does modern life really make it harder to fall in love? Or are we making it harder for ourselves? It is certainly the case today that contemporary couples benefit in different ways from relationships. Women no longer rely upon partners for economic security or status. A man doesn't expect his spouse to be in sole charge of running his household and raising his children. But perhaps the knowledge that we can live perfectly well without a partnership means that it takes much more to persuade people to abandon their independence. In theory, finding a partner should be much simpler these days. Only a few generations ago, your choice of soul mate (心上人) was constrained by geography, social convention and family tradition. Although it was never explicit, many marriages were essentially arranged. Now those barriers have been broken down. You can approach a builder or a brain surgeon in any bar in any city on any given evening. When the world is your oyster (牡蛎), you surely have a better chance of finding a pearl. But it seems that the old conventions have been replaced by an even tighter constraint: the tyranny of choice. The expectations of partners are inflated to an unmanageable degree: good looks, impressive salary, kind to grandmother, and right socks. There is no room for error in the first impression. We think that a relationship can be perfect. If it isn't, it is disposable. We work to protect ourselves against future heartache and don't put in the hard emotional labor needed to build a strong relationship. Of course, this is complicated by realities. The cost of housing and child-rearing creates pressure to have a stable income and career before a life partnership.

单选题Passive Smoking Is Workplace Killer Pressure mounted on Britain on Monday to take action on (51) smoking with new research showing second - hand smoke (52) about one worker each week in the hospitality industry (服务行业). Professor Knorad Jamrozik, of Imperial (帝国的) College in London, told a conference on environmental tobacco that second – hand (53) kills 49 employees in pubs, bars, restaurants and hotels each year and contributes to 700 deaths from lung cancer, heart (54) and stroke across the total national work force. "Exposure in the hospitality (55) at work outweighs (超过) the consequences of exposure of living (56) a smoker for those staff," Jamrozik said in an interview. Other (57) have measured the levels of exposure to passive smoking but Jamrozik calculated how it would translate into avoidable deaths. His findings are (58) on the number of people working in the hospitality industry in Britain, their exposure to second - hand smoke and their (59) of dying from it. Jamrozik said the findings would apply to (60) countries in Europe because, to a greater or (61) extent, levels of smoking in the community are similar. Professor Carol Black, president of the Royal College of Physicians, which sponsored the meeting, said the research is proof of the need for a ban on smoking in (62) places. "Environmental tobacco smoke in pubs, bars, restaurants and other public places is (63) damaging to the health of employees as well as the general public," she said in a statement. "Making these places smoke - free not only protects vulnerable (易受伤害的) staff and the public, it will (64) help over 300,000 people in Britain to stop smoking completely," she added. Ireland recently became the first country to introduce a national ban on smoking in public (65) . New York and parts of Australia have taken similar measures.

单选题Exercise Can Replace Insulin for Elderly Diabetics Most older people with so-called type Ⅱ diabetes could stop taking insulin if they would do brisk exercise for 30 minutes just three times a week, according to new medical research results reported in the Copenhagen newspaper Berlingske Tidende on Monday. Results from tests conducted on diabetics at the Copenhagen Central Hospital Rigshospitalet's Center for Muscle Research showed that physical exercise can boost the body's ability to utilise insulin by 30 percent, the newspaper reported. This is equal to the effect most elderly diabetics get from their insulin medication today, it said. Researchers had a group of non-diabetic men and a group of men with type Ⅱ, all more than 60 years of age, exercise on bicycles six times a week for three months. After the three months the doctors measured how much sugar the test subjects' muscles could utilise as a measure for how well their insulin worked. Associate Professor Dr. Flemming Dela of the Muscle Research Center said the tests demonstrated that the exercising diabetics had just as high insulin utilisation as the healthy non-exercising persons. "This means that the insulin works just as well for both groups. Physical exercise cannot cure people of diabetes, but it can eliminate almost all their symptoms. At the same time it can put off the point at which they have to begin taking insulin or perhaps completely avoid insulin treatment, " Dela was quoted as saying. Insulin isa hormone produced by the pancreas, controlling sugar in the body and used against diabetes. Dela said that to achieve the desired effect diabetics need only exercise to the point where they begin to work up a sweat, but that the activity has to be maintained since it wears off after five days without sufficient exercise. Most diabetics realise that they have to watch their diet while remaining unaware of the importance of exercise, Dela added.

单选题 Find Yourself Packing It On? Blame Friends Obesity can spread from person to person, much like a virus, researchers are reporting today. When one person gains weight, close friends tend to gain weight, too. Their study, published in The New England Journal of Medicine, involved a detailed analysis of a large social network of 12,067 people who were been closely followed for 32 years, from 1971 to 2003. The investigators knew who were friends with whom as well as who was a spouse or sibling or neighbor, and they knew how much each person weighed at various times over three decades. That let them reconstruct what happened over the years as individuals became obese. Did their friends also become obese? Did family members? Or neighbors? The answer, the researchers report, was that people were most likely to become obese when a friend became obese. That increased a person's chances of becoming obese by 57 percent. There was no effect when a neighbor gained or lost weight, however, and family members had less influence than friends. It did not even matter if the friend was hundreds of miles away, the influence remained. And the greatest influence of all was between close mutual friends. There, if one became obese, the other had a 171 percent increased chance of becoming obese, too. The same effect seemed to occur for weight loss, the investigators say. But since most people were gaining, not losing, over the 32 years, the result was, on average, that people grew fatter. Dr. Nicholas A. Christakis, a physician and professor of medical sociology at Harvard Medical School and a principal investigator in the new study, said one explanation was that friends affected each others' perception of fatness. When a close friend becomes obese, obesity may not look so bad. "You change your idea of what is an acceptable body type by looking at the people around you," Dr. Christakis said. The investigators say their findings can help explain why Americans have become fatter in recent years—each person who became obese was likely to drag along some friends. Their analysis was unique, Dr. Christakis said, because it moved beyond a simple analysis of one person and his or her social contacts and instead examined an entire social network at once, looking at how a person's friend's friends, or a spouse's sibling's friends, could have an influence on a person's weight. The effects, he said, "highlight the importance of a spreading process, a kind of social contagion, that spreads through the network." Of course, the investigators say, social networks are not the only factors that affect body weight. There is a strong genetic component at work, too. Science has shown that individuals have genetically determined ranges of weights, spanning perhaps 30 or so pounds for each person. But that leaves a large role for the environment in determining whether a person's weight is near the top of his or her range or near the bottom. As people have gotten fatter, it appears that many are edging toward the top of their ranges. The question has been why. If the new research is correct, it may say that something in the environment seeded what some call an obesity epidemic, making a few people gain weight. Then social networks let the obesity spread rapidly.
