单选题{{B}}Text 3{{/B}} People who begin to go deaf in adult life have different problems from those who are born deaf. They have to learn different ways of behaving and different ways of communication—perhaps at a time when learning is not all that easy. A heating aid is not a complete solution to the problem. The sound perceived by the deaf person through a hearing aid is distorted and appears to have more background noise than is heard by someone with normal hearing. Deafened people have to lip-read as well. Lipreading is difficult, demands intense concentration, and an uninterrupted direct view of the speaker's face. No other activities can take place at the same time: the lipreadar has to stop eating, stop everything in order to concentrate on hearing. It is not a question of stupidity or bad temper—as it sometimes appears to be—but a question of being very easy to misunderstand when tile sound is distorted. Remember what it's like trying to communicate on a very bad telephone line. Frustrating, isn't it? The deaf have to face that all the time. A useful way of looking at the problem is to see the deaf person as a foreigner—to treat them as if you were in a foreign country. You would speak more clearly, slowly and raise your voice slightly. And you'd use gestures to make your meaning clear, as well as have no hesitation in using pencil and paper to be absolutely certain. You can de all those things with the deaf—as well as making sure you don't obscure your mouth with your hand, a pipe or a cigarette. Another point quite often overlooked is that a hearing aid may be quite efficient and useful in a quiet, carpeted room—but try it in the street during rush hour, in a noisy ear, in a railway station ticket office, a cinema or a concert hall and you've got a really difficult problem to distinguish speech. So don't suggest to or encourage deaf people to go to functions which are going to make their disability appear worse—and increase their sense of failure. Careful selection of cinemas with good sound systems is important and you should experiment to find out where the best seats are for hearing. Fitting adaptors for radio and television, observing which 15lends are easier to understand, and making sure that people talking are well-lit are all useful and positive activities.

单选题Statins are a class of drugs that work to decrease the level of cholesterol in the blood. They are able to perform this function by effectively blocking the cholesterol — producing enzyme in the liver. In recent years, statins have increased in utility and popularity. Although a certain amount of cholesterol is imperative for the human body to function, an elevated level can cause a precarious situation in the body. CL Cholesterol affixes itself to arteries, lining them and inhibiting blood flow. Since less blood can travel through those encumbered arteries, the blood flow to the heart is adversely affected. Scientists have found that the walls of arteries in the body can become inflamed from this plaque buildup. In many instances, the end result of this decreased blood supply and inflammation is a heart attack — sometimes a fatal one. In other cases the blood supply to the brain is compromised by the plaque buildup, often causing a stroke. Decreased blood flow to the legs can cause leg pains or cramps. In short, arterial plaque buildup is never a healthy situation. Statins diminish the amount of cholesterol generated by the body. Although the drugs are not always able to reduce the amount of plaque that may already be clogging arteries, they can slow the production of new plaque. The drugs are also able to stabilize the plaques that are already present and make them less likely to cause problems in the body. Lowered cholesterol does not guarantee that a heart attack won't occur, but statin use will lower the risk for most patients. Not everyone who has a heart attack has high cholesterol levels, but most do have plaque formations on their arteries. It should be noted that the plaque is not always formed by high levels of cholesterol in the blood. Statins are generally prescribed by doctors for people with elevated cholesterol levels. As the mean weight of the American population has risen, so has the number of individuals with high cholesterol. Millions of men and women in this country are prescribed statins in an effort to decrease the amount of cholesterol in their blood. Remarkably, these effects can be seen in as little as two weeks after beginning a statin regime.

单选题Water is the giver and, at the same time, the taker of life. It covers most of the surface of the planet we live on and features large in the development of the human race. On present predictions, it is an cement that is set to assume even greater significance. Throughout history, water has had a huge impact on our lives. Humankind has always had a rather ambiguous relationship with water, on the one hand receiving enormous benefit from it, not just as a drinking source, but as a provider of food and a means whereby to travel and to trade. But forced to live close to water in order to survive and to develop, the relationship has not always been peaceful or beneficial. In fact, it has been quite the contrary. What has essentially been a necessity for survival was turned out in many instances to have a very destructive and life-threatening side. Through the ages, great floods alternated with long periods of drought have assaulted people and their environment, hampering their fragile fight for survival. The dramatic changes to the environment that are now a feature of our daily news are not exactly new: fields that were once lush and fertile are now barren; lakes and rivers that were once teeming with life are now long gone; savannah has been turned to desert. What perhaps is new is our native wonder when faced with the forces of nature. Today, we are more aware of climatic changes around the world. Floods in far-flung places are instant news for the whole world. Perhaps these events make us feel better as we face the destruction of our own property by floods and other natural disasters. In 2002, many parts of Europe suffered severe flood damage running into billions of euros. Properties across the continent collapsed into the sea as waves pounded the coastline wreaking havoc with sea defenses. But it was not just the seas. Rivers swollen by heavy rains and by the effects of deforestation carried large volumes of water that wrecked many communities. Building stronger and more sophisticated fiver defenses against flooding is the expensive short-term answer. There are simpler ways. Planting trees in highland areas, not just in Europe but in places like the Ganges Delta, is a cheaper and more attractive solution. Progress is already being made in convincing countries that the emission of carbon dioxide and other greenhouse gases is causing considerable damage to the environment. But more effort is needed in this direction. And the future? If we are to believe the forecasts, it is predicted that two thirds of the world population will be without fresh water by 2025. But for a growing number of regions of the world the future is already with us. While some areas are devastated by flooding, scarcity of water in many other places is causing conflict. The state of Texas in the United States of America is suffering a shortage of water with the Rio Grande failing to reach the Gulf of Mexico for the first time in 50 years in the spring of 2002, pitting region against region as they vie for water sources. With many parts of the globe running dry through drought and increased water consumption, there is now talk of water being the new oil. Other doom-laden estimates suggest that, while tropical areas will become drier and uninhabitable, coastal regions and some low-lying islands will in all probability be submerged by the sea as the polar ice caps melt. Popular exotic destinations now visited by countless tourists will become no-go areas. Today"s holiday hotspots of southern Europe and elsewhere will literally become hotspots—too hot to live in or visit, with the current erratic behavior of the weather, it is difficult not to subscribe to such despair. Some might say that this despondency is ill-founded, but we have had ample proof that there is something not quite fight with the climate. Many parts of the world have experienced devastating flooding. As the seasons revolve, the focus of the destruction moves from one continent to another. The impact on the environment is alarming and the cost to life depressing. It is a picture to which we will need to become accustomed.

单选题 After '9.11', the Olympic Games severely taxed the security services of the host country.

单选题Just over a year ago, I foolishly locked up my bicycle outside my office, but forgot to remove the pannier. When I returned the pannier had been stolen. Inside it were about ten of the little red notebooks I take everywhere for jotting down ideas for articles, short stories, TV shows and the like. When I lost my notebooks, I was devastated; all the ideas I"d had over the past two years were contained within their pages. 1 could remember only a few of them, but had the impression that those I couldn"t recall were truly brilliant. Those little books were crammed with the plots of award-winning novels and scripts for radio comedy shows that were only two-thirds as bad as the ones on at the moment. That"s not all, though. In my reminiscence, my lost notebooks contained sketches for many innovative and incredible machines. In one book there was a design for a device that could turn sea water into apple cider; in another, plan for an automatic dog; in a third, sketches for a pair of waterproof shoes with television screens built into the toes. Now all of these plans are lost to humanity. I found my notebooks again. It turns out they weren"t in the bike pannier at all, but in a bag in my spare room, where I found six months after supposedly losing them. And when I flipped through their pages, ready to run to the patent office in the morning, I discovered they were completely full of rubbish. Discovering the notebooks really shook me up. I had firmly come to believe they were brimming with brilliant, inventive stuff—and yet clearly they weren"t. I had deluded myself. After surveying my nonsense, I found that this halo effect always attaches itself to things that seem irretrievably lost. Don"t we all have a sneaking feeling that the weather was sunnier, TV shows funnier and cake-shop buns bunnier in the not-very-distant pasty. All this would not matter much except that it is a powerful element in reactionary thought, this belief in a better yesterday. After all, racism often stems from a delusion that things have deteriorated since "they" came. What a boon to society it would be if people could visit the past and see that it wasn"t the paradise they imagine but simply the present with different hats. Sadly, time travel is impossible. Until now, that is. Because I"ve suddenly remembered I left a leather jacket in an Indonesian restaurant a couples of years ago, and I"m absolutely certain that in the inside pocket there was a sketch I"d made.

单选题Years ago, a group of brilliant young men at the University of Wisconsin seemed to have amazing creative literary talent. They were 56 poets, novelists and essayists. They were extraordinary, in their ability, to put the English language 57 , These 58 young men met regularly to read and critique each other's work. And critique it they did! These men were merciless 59 one another. They 60 the most minute literary expression 61 a hundred pieces. They were heartless, tough, even mean in their criticism. The sessions became 62 arenas of literary criticism that the members of this exclusive club called them- selves "Stranglers." 63 , the women of literary talent in the university, were determined to start a club of 64 , one comparable to the Stranglers. They called themselves "Wranglers." They, too, read their works 65 . But there was one great difference. The criticism was much softer, more positive, more encouraging 66 there was 67 criticism at all. Every effort, even the most feeble one, was encouraged. Twenty years later, when an alumnus(男校友)of the university 68 an exhaustive study of his classmates' careers, he noticed a vast difference in the literary 69 of the Stranglers 70 the Wranglers. Of all the bright young men in the Stranglers, not one had made a significant literary accomplishment 71 . From the Wranglers had come six or more successful writers, some of national renown such as Marjorie Kinnan Rawlings. 72 wrote The Yearling. Talent between the two? Probably the same. Level of education? 73 difference. But the Stranglers strangled, while the Wranglers 74 to give each other a life. The Stranglers promoted an atmosphere of contention and self-doubt. The Wranglers 75 the best, not the worst.

单选题{{B}}Passage Seven{{/B}} It is hard to track the blue whale, the ocean's largest creature, Which has almost been killed off by commercial whaling and is now listed as an endangered species. Attaching radio devices to it is difficult and visual sightings are too unreliable to give real insight into its behavior. So biologists were delighted early this year when with the help of the Navy they were able to track a particular blue whale for 43 days monitoring its sounds. This was possible because of the Navy's formerly top-secret system of underwater listening devices spanning the oceans. Tracking whales is but one example of a exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies. Earth scientists announced at a news conference recently that they had used the system for closely monitoring a deep-sea volcanic eruption for the first time and that they plan similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures. The speed of sound in water is roughly one mile a second--slower than through land but faster than through air. What is most important, different layers of. ocean water can act as channels for sounds, focusing them in the same way a stethoscope (听诊器) does when it carries faint noises from a patient's chest to a doctor's ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low- frequency ones can often travel thousands of miles.

单选题Ever since this government's term began, the attitude to teachers has been overshadowed by the mantra that good teachers cannot be rewarded if it means bad teachers are rewarded, too. That's why, despite the obvious need for them, big pay rises have not been awarded to teachers across the board. The latest pay rise was 3.6 per cent--mad in the present situation. That's why, as well, the long battle over performance-related pay was fought as teacher numbers slid. The idea is that some kind of year zero can eventually be achieved whereby all the bad teachers are gone and only the good teachers remain. That is why the Government's attempts to relieve the teacher shortage have been so focused on offering incentives to get a new generation of teachers into training. The assumption is that so many of the teachers we have already are bad, that only by starting again can standards be raised. But the teacher shortage is not caused only because of a lack of new teachers coming into the profession. It is also because teaching has a retention problem, with many leaving the profession. These people have their reasons for doing so, which cannot be purely about wanting irresponsibly to "abandon" pupils more permanently. Such an exodus suggests that even beyond the hated union grandstanding, teachers are not happy. Unions and government appear to be in broad agreement that the shortage of teachers is a parlous state of affairs. Oddly, though, they don't seem entirely to agree that the reasons for this may lie in features of the profession itself and the way it is run. Instead, the Government is so suspicious of the idea that teachers may be able to represent themselves, that they have set up the General Teaching Council, a body that will represent teachers whether they want it to or not, and to which they have to pay ￡ 25 a year whether they want to or not. The attitudes of both sides promise to exacerbate rather than solve the problem. Teachers are certainly exacerbating the problem by stressing just how bad things are. Quite a few potential teachers must be put off. And while the Government has made quite a success of convincing the public that bad education is almost exclusively linked to bad teachers represented by destructive unions, it also seems appalling that in a survey last year, working hours for primary teachers averaged 53 hours per week, while secondary teachers clocked up 51 hours. At their spring conferences, the four major teaching unions intend to ballot their members on demanding from government an independent inquiry into working conditions. This follows the McCrone report in Scotland, which produced an agreement to limit hours to 35 per week, with a maximum class contact-time of 22 and a half hours. That sounds most attractive.
