单选题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 cells 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{{B}}Text 3{{/B}} Fate has not been kind to the western grey whale. Its numbers have dwindled to 130 or so, leaving it “critically endangered” in the eyes of the International Union for the Conservation of Nature. Fishing-nets, speeding ships, pollution and coastal development threaten the few that remain. Most recently, drilling for oil and gas in their main summer feeding grounds, near Sakhalin island off Russia’s Pacific coast, has brought fresh risks for the luckless creatures. Yet the rush to develop Sakhalin’s offshore fields may yet be the saviour of the species. When drilling was first discussed in the 1990s, there were muted complaints. When a consortium called Sakhalin. Energy, led by Royal Dutch Shell, announced plans to build an oil platform and lay pipelines in the only bay where the whales were known to congregate, these protests proliferated. In response, the consortium established an independent panel to advise it on how best to protect the whales and promised to fund its work. It subsequently agreed to change the route of the pipeline at the panel’s suggestion, although it refused to move the platform, as other critics had demanded. It also agreed either to follow the panel’s recommendations in future or to explain publicly why it was rejecting them. The platforms and pipelines are now complete. Sakhalin Energy exported its first cargo of liquefied natural gas last week. The project, says Shell, is an engineering triumph and a commercial success despite all the controversy. But has it been a success for the whales? Sakhalin Energy says their number seems to be growing by 2.5% a year, although Ian Craig, the firm’s boss, admits that the cause might be greater scrutiny rather than population growth. The scientists on the panel still seem worried. They complain that the firm has not always provided the information they need to assess the threat to the whales. It also has not always followed advice, the scientists’ advice about how noisy construction might scare the animals away, for example, or the speed that boats should travel to minimize the risk of hitting the whales. The scientists warn that the loss of just a few fertile females would be enough to tip the population into irrevocable decline. Last summer, there seemed to be far fewer whales around than normal. On the other hand, the panel knows this only because Sakhalin Energy funds lots of research on the whales. As a result, it has discovered that they have a wider range than originally thought, which might explain why so few of them showed up off Sakhalin island last year. Therefore, it is hard to escape the conclusion that, for creatures with a lot as sorry as the western grey whale, a nearby oil project is something of a blessing.

单选题Earlier this month the head of People for the Ethical Treatment of Animals, a non-profit organisation, wrote to Goldman Sachs. Animal shelters, the letter said, are struggling to cope with a surge in the number of pets that have been abandoned because their owners have fallen on hard times. Maybe Goldman executives should give their big bonuses to the dogs? Sadly, it looks unlikely. As the number of job losses and foreclosures has mounted over the past two years, some people have chosen to surrender their animals, unable to afford pet food let alone veterinary care. Many have brought their dogs and cats to shelters. Some have been less kind, chaining them to fences or locking them inside their foreclosed homes. One kitten was even left in a mailbox in Boston. Looking after these pets is becoming more challenging because many shelters rely on government money and have seen their funding cut. Animal Care and Control of New York City, for example, saw its grant fall by over $750,000 this fiscal year, around 7% of its operating budget. Fewer people are coming forward to make donations. Some non-profits are trying to step in and encourage people not to abandon their furry friends at shelters in the first place. Pet-food banks, which give pet food to people in need, have sprung up across the country. The Humane Society of the United States estimates that around 6m～8m cats and dogs end up in shelters each year. Only half are adopted. The rest are put down. There is some concern that even more are being put to sleep now, because shelters do not have the space or money to keep alive animals that have not been adopted. Fewer people are coming forward to adopt as well, presumably because they cannot afford to. One non-profit organisation, Pilots'N Paws, connects pilots to shelters with dogs that have not found homes. The pilots volunteer to fly them to other states, giving them a second chance at adoption. The Internet is playing its part. One organisation, ForeclosurePets. org, runs an online billboard that allows people facing foreclosure to find a home for their pets.Adopt-a-pet.com uses its website to help shelters advertise and send e-mail alerts when certain types of animals come in. By the end of 2009,8,500 animal shelters were using the site to post adoption listings for 140,000 pets, up from 6,800 shelters and 98,000 listings at the beginning of the year. Now all that is needed is 140,000 good homes.

单选题If soldiering was for the money, the Special Air Service (SAS) and the Special Boat Service (SBS) would have disintegrated in recent years. Such has been the explosion in private military companies (PMCs) that they employ an estimated 30,000 in Iraq alone—and no government can match their fat salaries. A young SAS trooper earns about ￡ 2,000 ($3,500 ) a month; on the "circuit", as soldiers call the private world, he could get ￡ 15,000. Why would he not'? For reasons both warm-hearted and cool-headed. First, for love of regiment and comrades, bonds that tend to be tightest in the most select units. Second, for the operational support, notably field medicine, and the security, including life assurance and pension, that come with the queen's paltry shilling. Although there has been no haemorrhaging of special force (SF) fighters to the private sector, there has been enough of a trickle to cause official unease. A memo recently circulated in the Ministry of Defence detailed the loss of 24 SF senior non-commissioned officers to private companies in the past year. All had completed 22 years of service, and so were eligible for a full pension, and near the end of their careers. Yet there is now a shortage of hard-bitten veterans to fill training and other jobs earmarked for them, under a system for retaining them known as "continuance." America has responded to the problem by throwing cash at it, offering incentives of up to $150,000 to sign new contracts. The Ministry of Defence has found a cheaper ploy. It has spread the story of two British PMC employees, recently killed in Iraq, whose bodies were left rotting in the sun.

单选题{{B}}Part A{{/B}}{{B}}Directions:{{/B}}Read the following four texts. Answer the questions below each text by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1.{{B}}Text 1{{/B}} Of all the areas of learning the most important is the development of attitudes: emotional reactions as well as logical thought processes affect the behavior of most people. "The burnt child fears the fire" is one instance; another is the rise of despots like Hitler. Both these examples also point up the fact that attitudes come from experience. In the one case the experience was direct and impressive; in the other it was indirect and cumulative. The Nazis were influenced largely by the speeches they heard and the books they read. The classroom teacher in the elementary school is in a strategic position to influence attitudes. This is true partly because children acquire attitudes from those adults whose words are highly regarded by them. Another reason it is true is that pupils often devote their time to a subject in school that has only been touched upon at home or has possibly never occurred to them before. To a child who had previously acquired little knowledge of Mexico his teacher's method of handling such a unit would greatly affect his attitude toward Mexicans. The media through which the teacher can develop wholesome attitudes are innumerable. Social studies (with special reference to races, creeds and nationalities), science matters of health and safety, the very atmosphere of the classroom... these are a few of the fertile fields for the inculcation of proper emotional reactions. However, when children go to school with undesirable attitudes, it is unwise for the teacher to attempt to change their feelings by cajoling or scolding them. She can achieve the proper effect by helping them obtain constructive experiences. To illustrate, first-grade pupils afraid of policemen will probably alter their attitudes after a classroom chat with the neighborhood officer in which he explains how he protects them. In the same way, a class of older children can develop attitudes through discussion, research, outside reading and all-day trips. Finally, a teacher must constantly evaluate her own attitudes, because her influence can be negative if she has personal prejudices. This is especially true in respect to controversial issues and questions on which children should be encouraged to reach their own decision as a result of objective analysis of all the facts.

单选题 Telecommuting, Internet shopping and online meetings may save energy as compared with in-person alternatives, but as the digital age moves on, its green reputation is turning a lot browner. Last year, E-mailing consumed as much as 1.5 percent of the nation's electricity-half of which comes from coal. In 2005 the computers of the world ate up 123 billion kilo-watt hours of energy. As a result, the power bill to run a computer over its lifetime will surpass the cost of buying the machine in the first place-giving Internet and computer companies a business reason to cut energy costs, as well as an environmental one. One of the biggest energy sinks comes not from the computers themselves but from the air-conditioning needed to keep them from overheating. For every kilowatt-hour of energy used for computing in a data center, another kilowatt-hour is required to cool the furnace like racks of servers. For Internet giant Google, this reality has driven efforts such as the installation of a solar array that can provide 30 percent of the peak power needs of its headquarters as well as increasing purchases of renewable energy. But to deliver Web pages within seconds, the firm must maintain hundreds of thousands of computer servers in cavernous buildings. "We are actively working to maximize the efficiency of our data centers, which account for most of the energy Google consumes worldwide." remarks Google's green energy czar Bill Weihl. Google will funnel some of its profits into a new effort, dubbed RE＜C (for renewable energy cheaper than coal, as Google translates it) to make sources such as solar-thermal, highaltitude wind and geothermal cheaper than coal "within years, not decades," according to Weihl. In the meantime, the industry as a whole has employed a few tricks to save watts. Efforts include rearranging the stacks of servers and the mechanics of their cooling, and using software to create multiple "virtual" computers, rather than having to deploy several real ones. Such virtualization has allowed computer maker Hewlett-Packard to consolidate 86 data centers spread throughout the world to just three, with three backups, says Pat Tiernan, the firm's vice president of social and environmental responsibility. The industry is also tackling the energy issue at the computer-chip level. Chipmakers such as Intel and AMD have shifted to so-called multi-core technology, which packs multiple processors into one circuit rather than separating them. "When we moved to multi-core and throttled down microprocessors, the energy savings were pretty substantial," says Allyson Klein, Intel's marketing manager. Chipmakers continue to shrink circuits on the nanoscale as well, which "means a chip needs less electricity" to deliver the same performance, she adds.
