单选题Leo Tolstoy was a Russian writer and moral philosopher, and one of the world's greatest novelists. He was born on April 30,1828 and died on Feb. 14, 1910. His writings (1) influenced much of 20th-century literature, and his moral (2) helped shape the thinking of several important (3) and political leaders. Leo Nikolayevich Tolstoy was born (4) a family of noble landowners at his family (5) south of Moscow. His early education came from tutors at home, but after the deaths of his parents in the 1830s, he was (6) by relatives. He entered Kazan' University when he was 16 but preferred to educate himself independently, and in 1847 he (7) his studies without finishing his degree. His next 15 years were very (8) .

单选题{{B}}Passage Two{{/B}} Our brains could be hard-wired to be male or female long before we begin to grow testes(丸)or ovaries(卵巢)in the womb. This discovery might explain why some people feel trapped in a body that's the wrong sex, and could also lead to tests that reveal the true "brain sex" of babies born with ambiguous genitalia(生殖器). Till now, the orthodoxy among developmental biologists has been that embryos develop ovaries and become female unless a gene called SRY on the Y chromosome is switched on. If this gene is active, it makes testes develop instead. This switch is seen as the key event in determining whether a baby is a girl or a boy. Only after the gonads(性腺) form and flood the body with the appropriate hormones, the theory goes, is the sex of our minds and bodies determined. But in a study of mice, a team at the University of California, Los Angeles, has now found that males and females show differences in the expression of no fewer than 50 genes well before SRY switches on. "It's the first discovery of genes differentially expressed in the brain, "says Eric Vilain, who led the UCLA team. "They may have an impact on the hard-wired development of the brain in terms of sexual differentiation independent of gonadal induction." Vilain is presenting details of seven of the 50 genes to the annual meeting of the American Society of Human Genetics in Baltimore this week. Three of these genes are dominant in females and four are dominant in males. The next step for Vilain and his team will be to show that the genes in question really do influence brain sexuality—and not just in mice. This is likely to be a much tougher proposition than merely showing there are differences in expression. But if the findings are confirmed, they could one day yield blood tests that allow doctors to establish the brain sex of babies born with genitalia that share features of both sexes. At present doctors and parents have to guess which gender to assign for surgical "correction".

单选题{{B}}Passage Five{{/B}} It was about 2 p.m. on Mar. 9 when three Nucor Corp. electricians got the call from their colleagues at the Hickman (Ark.) plant. It was bad news: Hickman's electrical grid had failed. For a minimill steelmaker like Nucor, which melts scrap steel from autos, dishwashers, mobile homes, and the like in an electric arc furnace to make new steel, there's little that could be worse. The trio immediately dropped what they were doing and headed out to the plant. No supervisor had asked them to make the trip, and no one had to. They went on their own. There wasn't any direct financial incentive for them to blow their weekends, no extra money in their next paycheck, but for the company their, contribution was huge. What's most amazing about this story is that at Nucor it's not considered particularly remarkable. "It could have easily been a Hickman operator going to help the Crawfordsville [Ind. ] mill," says Executive Vice-President John J. Ferriola "It happens daily." Nucor has nurtured one of the most dynamic and engaged workforces around. The 11 300 nonunion employees at the Charlotte (N. C. ) company don't see themselves as worker bees waiting for instructions from above. Nucor's flattened hierarchy and emphasis on pushing power to the front line lead its employees to adopt the mindset of owner-operators. Nucor gained renown in the late 1980s for its radical pay practices, which base the vast majority of most workers' income on their performance. An upstart nipping at the heels of the integrated steel giants, Nucor had a close-knit culture that was the natural outgrowth of its underdog identity. Legendary leader F. Kenneth Iverson's radical insight: that employees, even hourly clock-punchers, will make an extraordinary effort if you reward them richly,treat them with respect ,and give them real power. Nucor is an upstart no more, and the untold story of how it has clung to that core philosophy even as it has grown into the largest steel company in the U, S. is in many ways as compelling as the celebrated tale of its brash youth. Iverson retired in 1999. Under CEO Daniel R. DiMicco, a 23-year veteran, Nucor has snapped up 13 plants over the past five years while managing to instill its unique culture in all of the facilities it has bought, an achievement that makes him a more than worthy successor to Iverson.

单选题Last week 29 earnest American high school students were invited to an evening of receiving good words, small talk, warm toasts and fancy silverware. "Find out something about the person sitting next to you," advised former US Secretary of State Madeleine Albright. "Eventually, you'll discover they always have something interesting to say. And you should always use the proper silverware in the proper order. " Albright was the guest of honor at the imitated Official Dinner, which was a lot like a real official dinner in Washington minus the soft money. The evening was sponsored by the St. Albans School of Public Services to introduce its first class to the fine art of social survival. More than 84 guests, including students, teachers, school donors and speakers, gathered to replicate the lifestyle of the rich and political. The idea was to teach the social graces that will help students survive any social situation. Anyway, the whole proper fork thing is overrated. Former White House official C. Boyden Gray shared his top tips for surviving dinner parties: "Drink as little as possible until you get to dinner. " "Don't be the first person there or the last person to leave. " "Try to get more out of your dinner partners than they get out of you." Every Official Dinner has a greater reason for being. State dinners, for example, are either an opportunity to reward emerging democracies or strengthen old friendships. The Official Dinner was intended to show the students an elegant evening in Washington—part of the four-week intensive summer program to encourage public service. The students are from 13 states and two foreign countries. The program includes classes on the presidency, the courts, the media and international affairs. The students also debated public policy issues. "They're still at it at 10 o'clock at night," said director Mary Waikart. "That's good practice for Washington, isn't it?" Since there was no band, Albright offered herself up as the night's entertainer. No singing, but stories about her life in diplomacy. "Being secretary of state is the best job in the world," she said. " Better than being president, because you don't have to deal with the elections./
