单选题{{B}}Text 3{{/B}} Well, he made it up. All of it, apparently. According to a report published on December 29th by Seoul National University in South Korea, its erstwhile employee Hwang Woo-suk, who had tendered his resignation six days earlier, deliberately falsified his data in the paper on human embryonic stem cells that he and 24 colleagues published in Science in May 2005. In particular, Dr Hwang claimed he had created 11 colonies of human embryonic stem ceils genetically matched to specific patients. He had already admitted that nine of these were bogus, but had said that this was the result of an honest mistake, and that the other two were still the real McCoy. A panel of experts appointed by the university to investigate the matter, however, disagreed. They found that DNA fingerprint traces conducted on the stem-cell lines reported in the paper had been manipulated to make it seem as if all 11 lines were tailored to specific patients. In fact, none of them matched the volunteers with spinal-cord injuries and diabetes who had donated skin cells for the work. To obtain his promising "results", Dr Hwang had sent for testing two samples from each donor, rather than a sample from the donor and a sample of the cells into which the donor's DNA had supposedly been transplanted. The panel also found that a second claim in the paper — that only 185 eggs were used to create the 11 stem cell lines — was false. The investigators said the actual number of eggs used was far larger, in the thousands, although they were unable to determine an exact figure. The reason this double fraud is such a blow is that human embryonic stem-cell research has great expectations. Stem cells, which have not yet been programmed to specialise and can thus, in principle, grow into any tissue or organ, could be used to treat illnesses ranging from diabetes to Parkinson's disease. They might even be able to fix spinal-cord injuries. And stem cells cloned from a patient would not be rejected as foreign by his immune system. Dr Hwang's reputation, of course, is in tatters. The university is now investigating two other groundbreaking experiments he claims to have conducted — the creation of the world's first cloned human embryo and the extraction of stem cells from it, and the creation of the world's first cloned dog. He is also in trouble for breaching ethical guidelines by using eggs donated by members of his research team. And it is even possible that the whole farce may have been for nothing. Cloned embryos might be the ideal source of stem cells intended to treat disease, but if it proves too difficult to create them, a rough-and-ready alternative may suffice.

单选题Most of us think that, work is the central, dominating fact of life. We spend more than half our conscious hours at work, preparing for work, commute to and from work. What we do there largely determines our standard of living and to a great extent the status we are accorded by our fellow citizens as well. It is sometimes said that because leisure has become more important, the indignities and injustices of work can be pushed into a comer, that because most work is pretty intolerable, the people who do it should compensate for its boredom, frustrations and humiliations by concentrating their hopes on the other parts of their lives. I desperately reject that. For the foreseeable future the material and psychological rewards which work can provide, and the conditions in which work is done, will continue to play an essential part in determining the satisfaction that life can offer. Yet only a small minority can control the pace at which they work or the conditions in which their work is done; only for a small minority does work offer scope for creativity, imagination, or initiative. Inequality at work and in work is still one of the cruellest and most glaring forms of inequality in our society. We cannot hope to solve the more obvious problems of industrial fife, many of which arise directly or indirectly from the frustrations created by inequality at work, unless we tackle it head-on. Still less can we hope to create a decent and human society. The most glaring inequality is that between managers and the rest. For most managers, work is an opportunity and a challenge. Their jobs engage their interest and allow them to develop their abilities. They are constantly learning; they can exercise responsibility; they have a considerable degree of control over their own—and others"—working lives. The most important thing is that they have opportunity to initiate. By contrast, for most manual workers, and for a growing number of white-collar workers, work is a boring, dull, even painful experience. They spend all their working fives in conditions which would be regarded as intolerable—for themselves—by those who make the decisions which let such conditions continue. The majority have little control over their work; it provides them with no opportunity for personal development. Often production is so designed that workers are simply part of the technology. In offices, many jobs are so routine that workers justifiably feel themselves to be mere cogs in the bureaucratic machine. As a direct consequence of their work experience, many workers feel alienated from their work and their firm, whether it is in public or in private ownership.

单选题Many phrases used to describe monetary policy, such as "steering the economy to a soft landing" or "a touch on the brakes", makes it sound like a precise science. Nothing could be further from the truth. The relation between interest rates and inflation is uncertain. And there are long, variable lags before policy changes have any effect on the economy. Hence the analogy that likens the conduct of monetary policy to driving a car with a blackened windscreen, a cracked rearview mirror and a faulty steering wheel. Given all these disadvantages, central bankers seem to have had much to boast about. Average inflation in the big seven industrial economies fell to a mere 2.3% last year, close to its lowest level in 30 years, before rising slightly to 2.5% this July. This is a long way below the double-digit rates which many countries experienced in the 1970s and early 1980s. It is also less than most forecasters has predicted. In late 1994 the panel of economists which The Economist polls each month said that America's inflation rate would average 3.5% in 1995. In fact, it fell to 2.6% in August, and is expected to average only about 3% for the year as a whole. In Britain and Japan inflation is running half a percentage point below the rate predicted at the end of last year. This is no flash in the pan; over the past few years, inflation has been continually lower than expected in Britain and America. Economists have been particularly surprised by favourable inflation figures in Britain and the United States, since conventional measures suggest that both economies, and especially that of America, have little productive slack. America's capacity utilisation, for example, hit historically high levels earlier this year, and its jobless rate (5.6% in August) has fallen below most estimates of the natural rate of unemployment -- the rate below which inflation has taken off in the past. Why has inflation proved so mild? The most thrilling explanation is, unfortunately, a little defective. Some economists argue that powerful structural changes in the world have up-ended the old economic models which were based upon the historical link between growth and inflation.

单选题{{B}}Text 2{{/B}} Bacteria are microscopic organisms which live on the surface of objects. They are one of the most ancient living things, which exist on this planet for nearly 4,000 million years. Do you know the size of bacteria? It can only be measured in microns. Maybe you have not a standard in your mind how long a micron is. One micron is a thousandth of a millimeter, which equals about the diameter of a pinhead. Therefore, even if we enlarged the rounded bacterium a thousand times, it would only be the size of a pinhead. We barely see bacteria by a magnification an ordinary microscope of 100 times, even if we try, we cannot make out anything of their structure. There are normally millions of them together, for they can multiply really fast. Scientists have found that some bacteria have attached to wavy-looking "hairs" called flagella. The flagella rotate, pushing the bacteria through the water. Others can glide along over surfaces by some little-understood mechanism. Bacteria are so small that they are influenced by the movements of the chemical molecules around them. They are active all the time. Even the bacteria without flagella often bound about in the water. They are pushed here and there, colliding with the watery molecules. Bacteria cannot be detected because they don't produce bad odor or change the color or texture of the food. Therefore, when people eat the food with many bacteria, they are likely to get hepatitis A, acute gastroenteritis and a host of other illnesses. Many households have refrigerators to prevent from bacteria. Of course, freezing food slows or stops the growth of bacteria, however, when food is thawed, the bacteria will become reactivated. Bacteria can not be totally destroyed before the food is thoroughly cooked. We need to know that not all bacteria are in connection with illness. Just some bacteria can cause disease. They are called pathogenic bacteria. Fortunately our immune system can protect us from them. Bacteria are prokaryotes ( single cells that do not contain a nucleus). It may seem weird to classify organisms according to such details, but with or without a nucleus is not trivial at all. The division between prokaryotes and eukaryotes (all organisms with a nucleus inside their cells) is of extreme importance in biology, and is the result of a major evolutionary breakthrough.

单选题A number of recent books have reworked subjects, forms and writing techniques. Today's children read stories about divorce, death, drugs, air pollution, political extremism and violence. Relying on the magic of the illustrator, all kinds of books are being published. Before they know to read, babies can play with books made of cloth or books made to take in the bath. Later on, they are given picture books that may be cubical (立方形的) or triangular, outsized or very small. They also like work-books which come with watercolors and paintbrushes, and comic books (漫画册) filled with details where they have to spot a figure hidden among thousands of others. Not that the traditional children's books are being neglected. There are still storybooks where the pages pop up (跳起) when they are opened, to make a forest or a castle. Among the latest ideas are interactive stories where readers choose the plot (情节) or ending they want, and books on CD, which are very popular, in rich industrialized countries. The public has enthusiastically greeted the wealth of creativity displayed by publishers. "Previously, giving a child a book as often seen as improper," says Canadian author Marie-France Hebert. Her books, published by a French-language publisher, sell like hot cakes in hundreds of thousands of copies. "There's a real appetite for reading these days and I try to get across to children the passion for reading which is food for the mind and the heart, like a medicine or a vitamin.

单选题Popular education in England started as a social welfare as well as an educational service. Robert Raikes, who opened the first Sunday School in 1780, and the two bodies of religious and philanthropic people who provided all the day schools until 1870, were inspired to act by two motives--one was shame at the existence in a great country like England of children and many adults who could not read or write, and the other was concern at the conditions which the industrial revolution had provided for the swarms of children who inhabited the new towns. This approach to popular education was not the same in other countries. In Prussia, Switzerland, France and in the U. S. A. , the duty to see that future citizens were educated was recognized as that of the State, and public money was allotted to it much earlier than in England. Although the churches in some of these countries were associated with the State system--since religion was recognized to have an important share in the upbringing of the young--the prime motive force was education. The doctrines of the French Revolution were mainly responsible on the Continent for a first approach to educational opportunity, but these doctrines did not meet with the approval of the governing classes in this country. No statesman here at the beginning of the nineteenth century would have echoed Thomas Jefferson's famous saying of 1812 that "if a nation expects to be both free and ignorant it expects what never was and never can be in a state of civilization". The most our leaders achieved was the reluctant recognition, sixty years later, that "we must educate our masters". But if we were later than other nations in realizing the importance of popular education, our system has gained something from its dual (double) origin. We have, sooner than other countries, realized that education is not merely instruction, that schools are places where the very young children can be cared for, and that all children have bodies as well as minds.

单选题{{B}}Text 3{{/B}} Worldwide every day, we devour the energy equivalent of about 200 million barrels of oil. Most of the energy on earth comes from the sun. In fact enough energy from the sun hits the planet's surface each minute to cover our needs for an entire year, we just need to find an efficient way to use it. So far the energy in oil has been cheaper and easier to get at. But as supplies dwindle, this will change, and we will need to cure our addiction to oil. Burning wood satisfied most energy needs until the steam-driven industrial revolution, when energy-dense coal became the fuel of choice. Coal is still used, mostly in power stations, to cover one quarter of our energy needs, but its use has been declining since we started pumping up oil. Coal is the least efficient, unhealthiest and most environmentally damaging fossil fuel, but could make a comeback, as supplies are still plentiful; its reserves are five times larger than oil's. Today petroleum, a mineral oil obtained from below the surface of the Earth and used to produce petrol, diesel oil and various other chemical substances, provides around 40% of the world's energy needs, mostly fuelling automobiles. The US consumes a quarter of all oil, and generates a similar proportion of greenhouse gas emissions. The majority of oil comes from the Middle East, which has half of known reserves. But other significant sources include Russia, North America, Norway, Venezuela and the North Sea. Alaska's Arctic National Wildlife Refuge could be a major new US source, to reduce reliance on foreign imports. Most experts predict we will exhaust easily accessible reserves within 50 years, though opinions and estimates vary. We could fast reach an energy crisis in the next few decades, when demand exceeds supply. As conventional reserves become more difficult to access, others such as tar sands may be used instead. Petrol could also be obtained from coal. Since we started using fossil fuels ,we have released 400 billion tones of carbon, and burning the entire reserves could eventually raise world temperatures by 13℃. Among other horrors, this would result in the destruction of all rainforests and tile inching of all Arctic ice.

单选题The decision of the New York Philharmonic to hire Alan Gilbert as its next music director has been the talk of the classical-music world ever since the sudden announcement of his appointment in 2009. For the most part, the response has been favorable, to say the least. "Ooray! Last!" wrote Anthony Tommasini, a sober-sided classical-music critic. One of the reasons why the appointment came as such a surprise, however, is that Gilbert is comparatively little known. Even Tommasini, who had advocated Gilbert"s appointment in The Times, calls him"an unpretentious musician with no air of the formidable conductor about him." As a description of the next music director of an orchestra that has hitherto been led by musicians like Gustav Mahler and Pierre Boulez, that seems likely to have struck at least some The Times readers as faint praise. For my part, I have no idea whether Gilbert is a great conductor or even a good one. To be sure, he performs an impressive variety of interesting compositions, but it is not necessary for me to visit Avery Fisher Hall, or anywhere else, to hear interesting orchestral music. All I have to do is to go to my CD shelf, or boot up my computer and download still more recorded music from iTunes. Devoted concertgoers who reply that recordings are no substitute for live performance are missing the point. For the time, attention, and money of the art-loving public, classical instrumentalists must compete not only with opera houses, dance troupes, theater companies, and museums,but also with the recorded performances of the great classical musicians of the 20th century. There recordings are cheap, available everywhere, and very often much higher in artistic quality than today"s live performances; moreover,they can be "consumed" at a time and place of the listener"s choosing. The widespread availability of such recordings has thus brought about a crisis in the institution of the traditional classical concert. One possible response is for classical performers to program attractive new music that is not yet available on record. Gilbert"s own interest in new music has been widely noted. Alex Ross, a classical-music critic, has described him as a man who is capable of turning the Philharmonic into "a markedly different,more vibrant organization. " But what will be the nature of that difference? Merely expanding the orchestra"s repertoire will not be enough. If Gilbert and the Philharmonic are to succeed, they must first change the relationship between America"s oldest orchestra and the new audience it hopes to attract.
