单选题A male dental assistant, Miguel Alquicira, is in the minority. 11 he is also part of a special, if little noticed, shift in workplace gender patterns. Over the last decade, men have begun 12 to fields long the province of women. Mr. Alquicira, 21, graduated from high school in a 13 job market, one in which the traditional opportunities, 14 construction and manufacturing, for young men without a college degree had dried up (枯竭). After career consultants told him that 15 fields were growing, he borrowed money for an eight-month training course. 16 then, he has had no trouble finding jobs that pay $12 or $13 an hour. He gave little 17 to the fact that more than 90 percent of dental assistants are women. But then, young men like Mr. Alquicira have come of age in a world of inverted expectations, where women far outpace (超过) men in earning degrees and 18 to hold jobs that have turned out to be, by and large, more 19 , more difficult to outsource, and more likely to grow. "The way I look at it," Mr. Alquicira explained, "is that anything, 20 , that a woman can do, a guy can do."

单选题Is there enough oil beneath the Arctic National Wildlife Refuge (ANWR)to help secure America's energy future? President Bush certainly thinks so. He has argued that tapping ANWR's oil would help ease California's electricity crisis and provide a major boost to the country's energy independence. But no one knows for sure how much crude oil lies buried beneath the frozen earth, with the last government survey, conducted in 1998, projecting output anywhere from 3 billion to 16 billion barrels. The oil industry goes with the high end of the range, which could equal as much as 10% of U.S. consumption for as long as six years. By pumping more than 1 million barrels a day from the reserve for the next two to three decades, lobbyists claim, the nation could cut back on imports equivalent to all shipments to the U.S. from Saudi Arabia. Sounds good. An oil boom would also mean a multibillion-dollar windfall(意外之才) in tax revenues, royalties (开采权使用费)and leasing fees for Alaska and the Federal Government. Best of all, advocates of drilling say, damage to the environment would be insignificant. "We've never had a documented case of an oil rig chasing deer out onto the pack ice," says Alaska State Representative Scott Ogan. Not so fast, say environmentalists. Sticking to the low end of government estimates, the National Resources Defense Council says there may be no more than 3.2 billion barrels of economically recoverable oil in the coastal plain of ANWR, a drop in the bucket that would do virtually nothing to ease America's energy problems. And consumers would wait up to a decade to gain any benefits, because drilling could begin only after much bargaining over leases, environmental permits and regulatory review. As for ANWR's impact on the California power crisis, environmentalists point out that oil is responsible for only 1% of the Golden State's electricity output—and just 3% of the nation's.

单选题{{B}}Passage Three{{/B}} Few foods are more alluring than chocolate. "Chocolate is a drug of abuse in its own category," jokes Dr. Louis Aronne. "It's ahnost as if people have chocolate receptors in their brains. " That may not be too far off the mark. In a recent book called "Breaking the Food Seduction," Dr. Neal Barnard contends that certain foods—including chocolate, cheese, red meat and practically anything combining sugar and fat—are just plain addictive. " It's not that you lack willpower. These foods stimulate the release of chemicals in the brain's pleasure center that keep you hooked. " Besides tapping the brain's own "feel good" chemicals, Barnard says, some of these foods contain drug-like molecules (分子) of of their own. Cheese delivers casomorphins, the same compounds in a mother's milk that help an infant bond during nursing, he says, but cheese is even more powerful, because it delivers casomorphins in an undiluted form. The result: "We're bonding to our refrigerators. " Other scientists doubt these drug-like compounds have enough force to make the foods addictive. But no one denies that fat and sugar exert a strong appeal. The brain is designed to reward eating and other behaviors that promote survival. And throughout history, with food relatively hard to come by, what prmnoted survival better than calorie-dense foods packed with fat and sugar? Besides, fat and sugar also calm the brain, lowering levels of stress hormones. "That's why we call them comfort foods," says physiologist Mary Dallman. But comfort is different from addiction. In classic addiction, the brain grows less sensitive to a pleasurable substance, and the addict requires higher and higher doses to derive the same rewards. Can food cause that kind of change? Perhaps. In a new study, Ann Kelley offered rats either plain water or a high-calorie chocolate drink. Over a two-week period, the animals drank more and more chocolate, but produced fewer brain opiates(镇静剂) in response. "You see the same thing in rats on morphine or heroin," she says. Admittedly, some foods can be hard to stop eating. But these foods are less habit-forming than alcohol—and most people can enjoy a drink without becoming alcoholic. The real problem today may be that we're constantly surrounded with food—and can't undo millions of years of evolution.

单选题Oceanography has been defined as "the application of all sciences to the study of the sea". Before the nineteen century, scientists with an interest in the sea were few and far between. Certainly Newton considered some theoretical aspects of it in his writings, but he was reluctant to go to sea to further his work. For most people the sea was remote, and with the exception of early intercontinental travelers or others who earned a living from the sea, there was little reason to ask many questions about it, let alone to ask what lay beneath the surface. The first time that question "What is at the bottom of the oceans?" had to be answered with any commercial consequence was when the laying of a telegraph cable from Europe to America was proposed. The engineers had to know the depth profile of the route to estimate the length of cable that had to be manufactured. It was to Maury of the U.S. Navy that the Atlantic Telegraph Company turned, in 1853, for information on this matter. In the 1840s, Maury had been responsible for encouraging voyages during which soundings were taken to investigate the depths of the North Atlantic and Pacific Oceans. Later, some of his findings aroused much popular interest in his book The Physical Geography of the Sea. The cable was laid, but not until 1866 was the connection made permanent and reliable. At the early attempts, the cable failed and when it was taken out for repairs it was found to be covered in living growths, a fact which defied contemporary scientific opinion that there was no life in the deeper parts of the sea. Within a few years oceanography was under way. In 1872 Thomson led a scientific expedition, which lasted for four years and brought home thousands of samples from the sea. Their classification and analysis occupied scientists for years and led to a five-volume report, the last volume being published in 1895.
