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}} The planet's wild creatures face a new threat -- from yuppies, empty nesters, singletons and one parent families. Biologists studying the pressure on the planet's dwindling biodiversity today report on a new reason for alarm. Although the rate of growth in the human population is decreasing, the number of individual households is exploding. Even where populations have actually dwindled -- in some regions of New Zealand, for instance -- the number of individual households has increased, bemuse of divorce, career choice, smaller families and longer lifespans. Jianguo Liu of Michigan State University and colleagues from Stanford University in California re- port in Nature, in a paper published online in advance, that a greater number of individual house-holds, each containing on average fewer people, meant more pressure on natural resources. Towns and cities began to sprawl as new homes were built. Each household needed fuel to heat and light it; each household required its own plumbing, cooking and refrigeration. "In larger households, the efficiency of resource consumption will be a lot higher, because more people share things," Dr. Liu said. He and his colleagues looked at the population patterns of life in 141 countries, including 76 "hotspot" regions unusually rich in a variety of endemic wildlife. These hot spots included Australia, New Zealand, the US, Brazil, China, India, Kenya, and Italy. They found that between 1985 and 2000 in the "hotspot" parts of the globe, the annual 3.1% growth rate in the number of households was far higher than the population growth rate of 1.8%. "Had the average household' size remained at the 1985 level," the scientists report, "there would have been 155m fewer households in hotspot countries in 2000. Paradoxically, smaller households do not mean smaller homes. In Indian River county, Florida, the average area of a one-storey, single family house increased 33 % in the past three decades." Dr. Liu's work grew from the alarming discovery that the giant pandas living in China's Wolong reserve were more at risk now than they were when the reserve was first established. The local population had grown, but the total number of homes had increased more swiftly, to make greater inroads into the bamboo forests. Gretchen Daily of Stanford, one of the authors, said: "We all depend on open space and wild places, not just for peace of mind but for vital services such as crop pollination, water purification and climate stabilization. The alarming thing about this study is the finding that, if family groups continue to become smaller and smaller, we might continue losing biodiversity -- even if we get the aggregate human population size stabilised."

单选题Don't look now, but they're all around you. They're standing by the copy machine, hovering by the printer, answering the phone. Yes, they're the overworked, underappreciated interns: young, eager and not always paid. And with just 20% of the graduating class of 2009 gainfully employed, according to the National Association of Colleges and Employers, there are more and more of them each day. It seems the importance of internships for securing full-time work has dramatically increased over the years. Intern, previously used in the medical profession to define a person with a degree but without a license to practice, became a term for a physician in training following World War I, when medical school was no longer seen as preparation enough for practice. Later, the word migrated to politics as an alternative to the term apprentice as a reference to those interested in learning about careers in government. Meanwhile, co-op programs, in which students would work at a company for an extended period during college, emerged. From 1970 to 1983, the number of colleges and universities offering the programs increased from 200 to 1,000. Sure, it took an extra year to earn a B.A., but for three months each school year, students worked for companies they were interested in, tried out careers they weren't sure about and earned money to help cover tuition. Internship programs have produced several successes: Bill Gates was once a congressional page, and Oprah Winfrey worked at a CBS affiliate during her college years, just to name a few. Of course, Monica Lewinsky was a 22-year-old White House intern when she engaged in an intimate relationship with President Clinton, a scandal that still taints both offices. Today's interns are not limited to summer jobs at their local businesses. Some programs provide dorm housing in cities like New York and Washington, allowing students from around the country to work for the nation's biggest companies. Many popular cities even have Facebook groups devoted to providing social outings and networking opportunities for the thousands of interns who descend each summer. Though internships were formerly touted as an opportunity for students to explore career options, doing so now comes with a price. Some experts argue that internships punish those who might decide later than age 18 what they want to do with their life. More important, they can favor wealthier students, who can afford to not make any money during the summer, over the less privileged. Still, with pressure increasing on students to find work, the clamor for internships is only growing. To land that first job, career advisers now say, applicants should have two or more internships under their belt. Anyone who takes a summer to simply explore might be too late.

单选题A dependent audit comes from your employer, who wants proof that the people you're carrying on the company health plan really are your dependents. If you can't prove they are, the company will drop them. The goal is to ferret out children who are over age 18 and not in school, ex-spouses, sometimes even nieces or nephews—people, in short, who do not meet an employer's definition of dependent. If your company does not already conduct these audits, chances are it eventually will. And while it may strike you as an annoyance, do not ignore this task. Otherwise, eligible dependents could lose their health coverage. From an employer's perspective, audits make good business sense. Health care costs have been rising by 5 to 10 percent a year for over a decade, and employers want to contain those costs. An audit of a 10,000-person employer will typically uncover 200 to 500 ineligible dependents, said John Fazio, a senior consultant with the employee benefits firm Towers Watson. Removing these people, who cost a company an average of $ 2,100 a head, translates into annual savings of $ 420,000 to $1.05 million a year for the employer. Dependent audits have been around for more than a decade. But they have become popular in the last few years, as employers desperately sought ways to trim their health care budgets. This year 69 percent of large companies plan to conduct a dependent audit, up from the 55 percent that planned to do so in 2008, according to a March survey by Towers Watson and the National Business Group on Health, a nonprofit organization of large employers. From the employees' perspective, such audits are at best an annoyance, forcing them to gather paper work proving, say, that a child who had been covered for years remains eligible. At worst, an audit can be a wrenching and costly experience when a worker's dependent is found to be ineligible and has to get insurance elsewhere. What is more, a worker could become liable for the money that an employer paid out for a spouse or child who should not have been on the plan. And, as audits have become more common, the process for employees has become more onerous. "It used to be the honor system," says Michael Smith, the chief executive of ConSova, a dependent auditing company. Just five years ago, employers typically asked that you sign an affidavit stating that your dependent was eligible to be on your plan. "Now, they want documentation," Mr. Fazio said. "It's a more diligent process. " That means you may have to dig up birth and marriage certificates, bank statements, divorce agreements and other documents that prove your child or spouse are legal dependents.

单选题A pair of dice, rolled again and again, will eventually produce two sixes. Similarly, the virus that causes influenza is constantly changing at random and, one day, will mutate in a way that will enable it to infect billions of people, and to kill millions. Many experts now believe a global outbreak of pandemic flu is overdue, and that the next one could be as bad as the one in 1918, which killed somewhere between 25m and 50m people. Today however, advances in medicine offer real hope that another such outbreak can be contained—if governments start preparing now. New research published this week suggests that a relatively small stockpile of an antiviral drug—as little as 3m doses—could be enough to limit sharply a flu pandemic if the drugs were deployed quickly to people in the area surrounding the initial outbreak. The drug's manufacturer, Roche, is talking to the World Health Organisation about donating such a stockpile. This is good news. But much more needs to be done, especially with a nasty strain of avian flu spreading in Asia which could mutate into a threat to humans. Since the SARS outbreak in 2003 a few countries have developed plans in preparation for similar episodes. But progress has been shamefully patchy, and there is still far too little international coordination. A global stockpile of drugs alone would not be much use without an adequate system of surveillance to identify early cases and a way of delivering treatment quickly. If an outbreak occurred in a border region, for example, a swift response would most likely depend on prior agreements between different countries about quarantine and containment. Reaching such agreements is rarely easy, but that makes the task all the more urgent. Rich countries tend to be better prepared than poor ones, but this should be no consolation to them. Flu does not respect borders. It is in everyone's interest to make sure that developing countries, especially in Asia, are also well prepared. Many may bridle at interference from outside. But if richer nations were willing to donate anti-viral drugs and guarantee a supply of any vaccine that becomes available, poorer nations might be willing to reach agreements over surveillance and preparedness. Simply sorting out a few details now will have lives (and recriminations) later. Will there be enough ventilators, makes and drugs? Where will people be treated if the hospitals overflow? Will food be delivered as normal? Too many countries have no answers to these questions.

单选题{{B}}Text 3{{/B}} Success, it is often said, has many fathers--and one of the many fathers of computing, that most successful of industries, was Charles Babbage, a 19th-century British mathematician. Exasperated by errors in the mathematical tables that were widely used as calculation aids at the time, Babbage dreamed of building a mechanical engine that could produce flawless tables automatically. But his attempts to make such a machine in the 1920s failed, and the significance of his work was only rediscovered this century. Next year, at last, the first set of printed tables should emerge from a calculating "difference engine" built to Babbage's design. Babbage will have been vindicated. But the realization of his dream will also underscore the extent to which he was a man born ahead of his time. The effort to prove that Babbage's designs were logically and practically sound began in 1985, when a team of researchers at the Science Museum in London set out to build a difference engine in time for the 200th anniversary of Babbage's birth in 1992. The team, led by the museum's curator of computing, Doron Swade, constructed a monstrous device of bronze, iron and steel. It was 11 feet long, seven feet tall, weighed three tons, cost around $500 000 and took a year to piece together. And it worked perfectly, cranking out successive values of seventh-order polynomial equations to :31 significant figures. But it was incomplete. To save money, an entire section of the machine, the printer, was omitted. To Babbage, the printer was a vital part of design. Even if the engine produced the correct answers, there was still the risk that a transcription or typesetting error would result in the finished mathematical tables being inaccurate. The only way to guarantee error-free tables was to automate the printing process as well. So his plans included specifications for a printer almost as complicated as the calculating engine itself, with adjustable margins, two separate fonts, and the ability to print in two, three or four columns. In January, after years of searching for a sponsor for the printer, the Science Museum announced that a backer had been found. Nathan Myhrvold, the chief technology officer at Microsoft, agreed to pay for its construction (which is expected to cost $373 000 with one Proviso: that the Science Museum team would build him an identical calculating engine and printer to decorate his new home on Lake Washington, near Seattle). Construction of the printer will begin--in full view of the public--at the Science Museum later this month. The full machine will be completed next year. It is a nice irony that Babbage's plans should be realized only thanks to an infusion of cash from a man who got rich in the computer revolution that Babbage helped to foment. More striking still, even using 20th-century manufacturing technology the engine will have cost over $830 000 to build. Allowing for inflation, this is roughly a third of what it might have cost to build in Babbage's day-in contrast to the cost of electronic-computer technology, which halves in price every 18 months. That suggests that, even had Babbage succeeded, a Victorian computer revolution based on mechanical technology would not necessarily have followed.
