单选题{{B}}Passage Four{{/B}} Lead deposits, which accumulated in soil and snow during the 1960's and 1970's, were primarily the result of leaded gasoline emissions originating in the United States. In the twenty years that the Clean Air Act has mandated unleaded gas use in the United States, the lead accumulation world-wide has decreased significantly. A study published recently in the journal Nature shows that air-borne leaded gas emissions from the United States were the leading contributor to the high concentration of lead in the snow in Greenland. The new study is a result of the continued research led by Dr. Charles Boutron, an expert on the impact of heavy metals on the environment at the National Center for Scientific Research in France. A study by Dr. Boutron published in 1991 showed that lead levels in arctic (北极的) snow were declining. In his new study, Dr. Boutron found the ratios of the different forms of lead in the leaded gasoline used in the United States were different from the ratios of European, Asian and Canadian gasolines and thus enabled scientists to differentiate (区分) the lead sources. The dominant lead ratio found in Greenland snow matched that found in gasoline from the United States. In a study published in the journal Ambio, scientists found that lead levels in soil in the North-eastern United States had decreased markedly since the introduction of unleaded gasoline. Many scientists had believed that the lead would stay in soil and snow for a longer period. The authors of the Ambio study examined samples of the upper layers of soil taken from the same sites of 30 forest floors in New England, New York and Pennsylvania in 1980 and in 1990. The forest environment processed and redistributed the lead faster than the scientists had expected. Scientists say both studies demonstrate that certain parts of the ecosystem (生态系统)respond rapidly to reductions in atmospheric pollution, but that these findings should not be used as a license to pollute.

单选题{{B}}Passage Five{{/B}} Even before Historian Joseph Ellis became a best-selling author, he was famous for his vivid lectures. In his popular courses at Mount Holyoke College in Massachusetts, he would often make classroom discussion lively by describing his own combat experience in Vietnam. But as Ellis's reputation grew--his books on the Founding Fathers have won both the prestigious National Book Award and the Pulitzer Prize--the history professor began to entertain local and national reporters with his memories of war. Last year, after The Boston Globe carried accounts of Ellis's experience in the Vietnam war, someone who knew the truth about Ellis dropped a dime (揭发) . Last week The Boston Globe revealed that Ellis, famous for explaining the nation's history, had some explaining to do about his own past. "Even in the best of lives, mistakes are made," said a wretched Ellis. It turned out that while the distinguished historian had served in the Army, he'd spent his war years not in the jungles of Southeast Asia, but teaching history at West Point (西点军校). He'd also overstated his role in the antiwar movement and even his high-school athletic records. His admission shocked colleagues, fellow historians and students who wondered why someone so accomplished would beautify his past. But it seems that success and truthfulness don't always go hand in hand. Even among the distinguished achievers, security experts say, one in ten is deceiving--indulging in everything from empty boasting to more serious offenses such as plagiarism (剽窃), fictionalizing military records, making up false academic certificates or worse. And, oddly, prominent people who beautify the past often do so once they're famous, says Ernest Brod of Kroll Associates, which has conducted thousands of background checks. Says Brod: "It's not like they use these lies to climb the ladder." Then what makes them do it? Psychologists say some people succeed, at least in part, because they are uniquely adjusted to the expectations of others. And no matter how well-known, those people can be haunted by a sense of their own shortcomings. "From outside, these people look anything but fragile," says Dennis Shulman, a New York psychoanalyst. "But inside, they feel hollow, empty."
