While consumers pay for perceived shortages at the pump, scientists and economists struggle to reach consensus over "proven oil reserves," or how much oil you can realistically mine before recovery costs outstrip profits. Economist Leonardo Maugeri fired up the debate that accused the "oil doomsters" of crying wolf. Oil pessimists estimate that maximum oil production around the globe will peak in 2008 as demand rises from developing economies such as China. "If you squeezed all the oil in Iraq into a single bottle, you could fill four glasses, with the world consuming one glass of oil each year," says a physicist. "We've consumed nine bottles since oil was discovered, and we have another 9 or 10 in the refrigerator. How many more are there？ Some say five or six, but we say three." Others believe, like Maugeri, that the number of glasses is virtually limitless. John Felmy, chief economist at the American Petroleum Institute, argues that peak oil-production estimates are so far off that. "Ever since oil was first harvested in the 1800s, people have said we'd run out of the stuff," Felmy says. In the 1880s a Standard Oil executive sold off shares in the company out of fear that its reserves were close to drying up. Some scientists said in the 1970s that we'd hit peak oil in 2003. It didn't happen. If there is an end to the debate, advanced oil-recovery technologies will most likely find it. A new seismic survey technique, for instance, sends sound waves of varying frequencies thousands of meters belowground. Microphones arrayed aboveground record the reflected signals, and computer software models a 3-D portrait of possible oil hot spots. The surveys have now added a fourth dimension, creating a time-lapse simulation of fluid movements. Companies are also finding sophisticated ways to mine more oil from existing wells. Flexible, coiled-tube drills that carve out horizontal side paths are a marked improvement over conventional, rigid drills that move only straight down. Using such technology, companies hope to soon harvest 50 to 60 percent of oil from existing wells, up from today's 35 percent. Biotechnology, too is keeping the black gold flowing. University of Albert scientists are searching for microorganisms that could dilute viscous, hard-to-recover oil and make it flow more freely. "Technology can help push peak oil production further and further out," says an expert. But only time will tell when oil production will peak. According to the passage, which of the following statements is true？ A．How long the oil age will last is simply an academic question. B．The oil price this year set a new record. C．Shell Group reduced its reserves to 4.5 billion barrels this year. D．Economists disagree with one another on how much oil you can realistically mine.

British surnames fall mainly into four broad categories: patronymic, occupational, descriptive and local. A few names, it is true, will remain puzzling: foreign names, perhaps, crudely translated, adapted or abbreviated; or artificial names. In fact, over fifty percent of genuine British surnames derive from place names of different kinds, and so they belong to the last of our four main categories. Even such a name as Simpson may belong to this last group, and not to the first, had the family once had its home in the ancient village of that name. Otherwise, Simpson means "the son of Simon", as might be expected. Hundreds of occupational surnames are at once familiar to us, or at least recognizable after a little thought: Arther, Carter, Fisher, Mason, Thatcher, Taylor, to name but a few. Hundreds of others are more obscure in their meanings and testify to the amazing specialization in medieval arts, crafts and functions. Such are "Day", (Old English for breadmaker) and "Walker" (a fuller whose job was to clean and thicken newly, made cloth). All these vocational names carry with them a certain gravity and dignity, which descriptive names often lack. Some, it is true, like "Long", "Short" or "Little", are simple. They may be taken quite literally. Others require more thinking: their meanings are slightly different from the modern ones. "Black" and. "White" implied dark and fair respectively. "Sharp" meant genuinely discerning, alert, acute rather than quick-witted or clever. Place-names have a lasting interest since there is hardly a town or village in all England that has not at some time given its name to a family. They may be picturesque, even poetical; or they may be pedestrian, even trivial. Among the commoner names which survive with relatively little change from old-English times are "Mil ton" (middle enclosure) and "Hilton" (enclosure on a hill). Surnames are said to be ______ in Anglo-Saxon England. A．common B．vocational C．unusual D．descriptive

Among the many shaping factors, I would single out the country's excellent elementary schools: a labor force that we l comed the new technology; the practice of giving premiums to inventors; and above all the American genius for nonverbal, "spatial" thinking about things technological.
