If you choose lobster from a menu, then wherever you are in the world, the odds are that your dinner may have come from Arichat in Nova Scotia. The lobster, trapped off the Canadian coast, would have been driven to Louisville, Kentucky, where, cocooned in gel packs and styrofoam, it went for a wild ride on the carousels of the UPS superhub, where 17,000 high-speed conveyor belts, carrying more than 8m packages a week, whisk your living lobster to a plane and on onto tables across the globe. John McPhee's new book is about supply lines: how a lobster shares a conveyor belt with Bentley spare parts and jockey underwear. It is about boats, trains and trucks, but mostly it is about the people who drive, tend and love the machines. Don Ainsworth owns an 18-wheeler with 'a tractor of such dark sapphire that only bright sunlight could bring forth its colour.' To wash his truck Mr. Ainsworth uses only water that has either been de-ionised or has undergone reverse-osmosis; anything else leaves spots. 'This is as close as a man will ever know', he says, 'what it feels like to be a truly gorgeous woman. People give us looks, going thumbs up. ' He carries chemicals all across North America where his enemies are gators, bears and four-wheelers. 'Gators are huge strips of shredded tyre littering the highways and just one of them 'can rip off your fuel-crossover line'. A bear is a policeman, while a four-wheeler is any vehicle that has fewer than 18 wheels. They buzz around like gnats, seemingly unaware that a real vehicle, one with 18 wheels or more, cannot stop on a dime. The Billy Joe Bolingis a towboat which, perversely, pushes 15 barges up the Illinois River. The barges carry 30,000 tons of pig-iron, steel, coils, fertiliser and furnace coke. Lashed together with steel cables which are then tightened with cheater bars, the Billy Joe Bolingshoves forward a metal raft that is longer than an aircraft carrier. Along the way, the captain copes with bridges, locks, currents, shoals, winter ice 18 inches thick and summer ladies flashing at him. 'We brought 12,000 tons of coke up the Illinois River,' the skipper tells the author, 'and now we're pushing 14,000 tons of coke down the Illinois River. One day they'll figure it out and put us out of a job. ' The bosses also want to put the drivers of the coal train out of a job. They dream of automated trains running endlessly along the 1,800 miles between the strip-mines of the Powder River Basin and Georgia's Plant Scherer, the world's largest coal-fired power station. A mile-and-half long train has 133 gondolas, each of which carries 115 tons of coal, and the whole trainload will keep Plant Scherer burning for just eight hours. This book will keep you much longer. It is Mr. McPhee at his wise, wry best, writing in top gear which, as Mr Ainsworth will tell you, is the 18th: 'the going home gear, the smoke hole'.

Passage One The world is going through the biggest wave of mergers and acquisitions ever witnessed. The process sweeps from hyperactive America to Europe and reaches the emerging countries with unsurpassed might. Many in these countries are looking at this process and worrying: 'Won't the wave of business concentration turn into an uncontrollable anti-competitive force?' There's no question that the big are getting bigger and more powerful. Multinational corporations accounted for less than 20% of international trade in 1982. Today the figure is more than 25% and growing rapidly. International affiliates account for a fast-growing segment of production in economies that open up and welcome foreign investment. In Argentina, for instance, after the reforms of the early 1990s, multinationals went from 43% to almost 70% of the industrial production of the 200 largest firms. This phenomenon has created serious concerns over the role of smaller economic firms, of national businessmen and over the ultimate stability, of the world economy. I believe that the most important forces behind the massive MA wave are the same that underlie the globalization process: falling transportation, and communication costs, lower trade and investment barriers and enlarged markets that require enlarged operations capable, of meeting customers' demands. All these are beneficial, not detrimental to consumers. As productivity grows, the world's wealth increases. Examples of benefits or costs of the current concentration wave are scanty. Yet it is hard to imagine that the merge of a few oil firms today could recreate the same threats to competition that were feared nearly a century ago in the U.S., when the Standard Oil trust was broken up. The mergers of telecom companies, such as World Corn, hardly seem to bring higher prices for consumers or a reduction in the pace of technical progress. On the contrary, the price of communications is coming down fast. In cars, too, concentration is increasing—witness Daimler and Chrysler, Renault and Nissan—but it does not appear that consumers am being hurt. Yet the fact remains that the merger movement must be watched. A few weeks ago, Alan Greenspan warned against the megamergers in the banking industry. Who is going to supervise, regulate and operate, as lender of last resort with the gigantic banks that are being created? Won't multinationals shift production from one place to another when a nation gets too strict about infringements to fair corn petition? And should one country take upon itself the role of 'defending competition' on issues that affect many other nations, as in the U. S..

Mike and Adam Hurewitz grew up together on Long Island, in the suburbs of New York City. They were very close, even for brothers. So when Adam's liver started failing, Mike offered to give him half of his. The operation saved Adam's life. But Mike, who went into the hospital in seemingly excellent health, developed a complication—perhaps a blood colt—and died last week. He was 57. Mike Hurewitz's death has prompted a lot of soul searching in the transplant community. Was it a tragic fluke or a sign that transplant surgery has reached some kind of ethical limit? The Mount Sinai Medical Center, the New York City hospital where the complex double operation was performed, has put on hold its adult living donor liver transplant program, pending a review of Hurewitz's death. Mount Sinai has performed about 100 such operations in the past three years. A 1-in-100 risk of dying may not seem like bad odds, but there's more to this ethical dilemma than a simple ratio. The first and most sacred rule of medicine is to do no harm. 'For a normal healthy person a mortality rate 1% is hard to justify,' says Dr. John Fung, chief of transplantation at the University of Pittsburgh Medical Center. 'If the rate stays at 1%, it's just not going to be accepted.' On the other hand, there's an acute shortage of traditional donor organs from people who have died in accidents or suffered fatal heart attacks. If family members fully understand the risks and are willing to proceed, is there any reason to stand in their way? Indeed, a recent survey showed that most people will accept a mortality rate for living organ donors as high as 20%. The odds, thankfully, aren't nearly that bad. For kidney donors, for example, the risk ranges from 1 in 2,500 to 1 in 4,000 for a healthy volunteer. That helps explain why nearly 40% of kidney transplants in the U. S. come from living donors. The operation to transplant a liver, however, is a lot trickier than one to transplant a kidney. Not only is the liver packed with blood vessels, but it also makes lots of proteins that need to be produced in the right ratios for the body to survive. When organs from the recently deceased are used, the surgeon gets to pick which part of the donated liver looks the best and to take as much of it as needed. Assuming all goes well, a healthy liver can grow back whatever portion of the organ is missing, sometimes within a month. A living-donor transplant works particularly well when an adult donates a modest portion of the liver to a child. Usually only the left lobe of the organ is required, leading to a mortality rate for living-donors in the neighborhood of 1 in 500 to 1 in 1, 000. But when the recipient is another adult, as much as 60% of the donor's liver has to be removed. 'There really is very little margin for error,' says Dr. Fung. By way of analogy, he suggests, think of a tree. 'An adult-to-child living-donor transplant is like cutting off a limb. With an adult-to-adult transplant, you're splitting the trunk in half and trying to keep both halves alive. ' Even if a potential donor understand and accepts these risks, that doesn't necessarily mean the operation should proceed. All sorts of subtle pressures can be brought to bear on such a decision, says Dr. Mark Siegler, director of the MacLean for Clinical Medical Ethics at the University of Chicago. 'Sometimes the sicker the patient, the greater the pressure and the more willing the donor will be to accept risks. ' If you feel you can't say no, is your decision truly voluntary? And if not, is it the medical community's responsibility to save you from your own best intentions? Transplant centers have developed screening programs to ensure that living donors fully understand the nature of their decision. But unexamined, for the most part, is the larger issue of just how much a volunteer should be allowed to sacrifice to save another human being. So far, we seem to be saying some risk is acceptable, although we're still vaguer about where the cutoff should be. There will always be family members like Mike Hurewitz who are heroically prepared to make the ultimate sacrifice for a loved one. What the medical profession and society must decide is if it's appropriate to let them do so.

阅读理解Passage FourHenry Ford, the famous U. S. inventor and car manufacture, once said, The business of America is business. By this he meant that the U. S. way of life is based on the values of the business world.Few would argue with Fords statement. A brief glimpse at a daily newspaper vividly shows how much people in the United States think about business. For example, nearly every newspaper has a business section, in which the deals and projects, finances and management, stock prices and labor problems of corporations are reported daily. In addition, business news can appear in every other section. Most national news has an important financial aspect to it. Welfare, foreign aid, the federal budget, and the policies of the Federal Reserve Bank are all heavily affected by business. Moreover, business news appears in some of the unlikeliest places. The world of arts and entertainment is often referred to as 4tthe entertainment industry or show businessThe positive side of Henry Fords statement can be seen in the prosperity that business has brought to U. S. life. One of the most important reasons so many people from all over the world come to live in the United States is the dream of a better job. Jobs are produced in abundance (大量地)because the U. S.economic system is driven by competition. People believe that this system creates more wealth, more jobs, and a materially better way of life.The negative side of Henry Fords statement, however, can be seen when the word business is taken to mean big business. And the tom big business referring to the biggest companies, is seen in opposition to labor. Throughout U. S. history working people have had to fight hard for higher wages, better working conditions, and the righl to form unions. Today, many of the old labor disputes arc over, but there is still some employee anxiety. Downsizing—the laying off of thousands of workers to keep expenses low and profits high—creates feelings of insecurity for many.

阅读理解Directions: For this rusk, you are to read a short passage with 5 questions. Read the passage carefully Then answer the questions in the fewest possible words on the Answer Sheet.Three hundred years ago news travelled by word of mouth or letter, and circulated in taverns and coffee houses in the form of pamphlets and newsletters. “The coffee houses particularly are very roomy for a free conversation, and for reading at an easier rate all manner of printed news, ” noted one observer. Everything changed in 1833 when the first mass-audience newspaper, The New York Sun, pioneered the use of advertising to reduce the cost of news, thus giving advertisers access to a wider audience. The penny press, followed by radio and television, turned news flora a two-way conversation into a one-way broadcast, with a relatively small number of firms controlling the media.Now, the news industry is returning to something closer to the coffee house. The internet is making news more participatory, social and diverse, reviving the discursive characteristics of the era before the mass media. That will have profound effects on society and politics. In much of the world, the mass media are flourishing. Newspaper circulation rose globally by 6% between 2005and 2009. But those global figures mask a sharp decline in readership in rich countries.Over the past decade, throughout the Western world, people have been giving tip newspapers and TV news and keeping up with events in profoundly different ways. Most strikingly, ordinary people are increasingly involved in compiling, sharing, filtering, discussing and disturbing news. Twitter lets people anywhere report what they are seeing. Classified documents are published in their thousands online. Mobile phone footage of Arab uprisings and American tornadoes is posted on social networking sites and shown on television newscasts. Social networking sites help people find discuss and share news with their friends.And it is not just readers who are challenging the media elite. Technology firms including Google, Facebook and Twitter have become important conduits of news. Celebrities and world leaders publish updates directly via social networks: many countries now make raw data available through “open government” initiatives. The internet lets people read newspapers or watch television channels from around the world. The web has allowed new providers of news, from individual bloggers to sites, to prominence in a very short space of time. And it has made possible entirely new approaches to journalism, such as that practiced by Wikileaks, which provides an anonymous way for whistleblowers to publish documents. The news agenda is no longer controlled by a few press barons and state outlets.In principle, every, liberal should celebrate this. A more participatory and social news environment, with a remarkable diversity and range of news sources, is a good thing. The transformation of the news business is unstoppable, and attempts to reverse it are doomed to failure. As producers of new journalism, individuals can be scrupulous with facts and transparent with their sources. As consumers, they can be general in their tastes and demanding in their standards. And although this transformation does raise concerns, there is much to celebrate in the noisy, diverse, vociferous, argumentative and stridently alive environment of the news business in the age of the Internet. The coffee house is back. Enjoy it.

阅读理解Directions: There are three passages in (his section. Eachpassage is followed by some questions or unfinishedstatements. For each of them there are four choices markedA, B, C and D. You should decide on the best choice andthen blacken the corresponding letter on the Answer Sheet.Passage ThreeAlong with red letterboxes and telephone booths, London’ s black taxis are touted as symbolic of the city. Fully 25, 600 drivers trundle around the capital’ s streets. They are privileged: unlike minicabs, they can pick up passengers hailing in the street and run on a pricey meter system rather than a fixed fee. Nationally the average fare is 5. 77 ($9. 56) for two miles; in London it is 7. 20. All cabbies are required to pass the “knowledge” , a test of all the roads within a six-mile radius of central London. If they take a daft route to their destination it is usually deliberate.But becoming a taxi driver is ever harder. In the 1970s the knowledge took around 23months to complete. Last year it took 50 months. “You can get a PhD in the same time. ” complains Malcolm Paice of City Fleet, a radio-taxi firm. Between 2009 and 2012, the number of taxi drivers increased by only 4% in London. Faced with such a high barrier to entry, more people are taking a shorter course that only allows them to drive black cabs in suburban areas, says Tom Moody Of Transport for London (TfL) .But in the same period the number of minicab drivers in London jumped by 19% to 67, 000,The scorn they receive from black-taxi drivers is little deserved. Liana Griffin, the boss of Addison Lee, a large minicab firm, says minicabs have become more comparable to black cabs since 2004, when regulations and criminal- record checks were introduced. All of the company s drivers take a six week course and rely on satellite navigation system__ as do some black-taxi drivers. Their fares are around a third cheaper, Mr. Griffin says.Technology is further bulldozing the distinction between black taxis and minicabs. Fully 14, 000 London taxis have signed up with Hailo, an app for ordering cabs that was introduced to London in 2011. Ron Zeghibe, Hailo’ s chairman, says that some drivers shun taxi ranks or “street work” in favor of punters who order through his service. Minicab companies have their own, similar, apps. One, from Greentomatocars, helped the firm nearly double in revenue in a year.Yet the separation between the two kinds of taxis looks likely to stay. In April the Law Commission, an independent body, will release a report on the taxi trade. Many of its recommendations will boost minicabs outside London. Larger firms Such as Addison Lee will find it easier to expand as licensing rules are simplified. But London’ s black cabs look likely to be protected. They will still be regulated by TfL; barriers to entry will remain high. Instead of nurturing a dwindling trade, this could have the opposite effect. Black cabs might soon become as quaintly archaic as telephone booths.
