单选题Don't call him just a college professor. Internet entrepreneur, TV personality, advisor to presidents, and friend to the rich and powerful would be more accurate. Henry Louis "Skip" Gates Jr. is better known for his activities outside the academy. This week he sold Africana. com, a website he created with a fellow Harvard University professor, to Time Warner. Terms of the deal weren't revealed, though the Wall Street Journal pegged the price at more than $ 10 million, with Gates reaping up to $ 1 million. Time Warner will incorporate the site, a portal with news and information about people of African descent, into America Online when the two merge as expected. The sense is that Gates got a very good deal. The site is a rich source of scholarship but hardly a rich source of revenue. As recently as the late 1980s Gates, who turns 50 this week, was an obscure professor, penning books on literary theory only a graduate student could love. Now he can't be avoided: He hosted a series about Africa on public television, writes occasional articles for the New Yorker, and even advises the Gore presidential campaign. He counts director Steven Spielberg, Microsoft's Bill Gates and President Clinton as friends. "They're not intimate friends," he insists. Indeed, Gates has evolved into a kind of expert on everything African-American. "He remains the go-to person on the state of African-American affairs," said Perry Steinberg, head of American Program Bureau, a lecture agency. The 30 or so speeches Gates delivers each year are another source of income for the professor. With fame comes controversy. Several other black intellectuals have taken him to task for not being confrontational enough. Gates has heard it before. "Me? Critics? Oh, what a shock. " But he considers himself more a descendent of historian and educator W. E. B. Du Bois than of Malcolm X. His ultimate goal is to build the field of Afro-American studies. "Fifty years from now I want there to be at least 10 great centers of Afro-American studies," he says. If working as a consultant on Spielberg's historical film Amistad or giving Al Gore advice helps, so be it.

单选题Mycorrhizal fungi infect more plants than do any other fungi and are necessary for many plants to thrive, but they have escaped widespread investigation until recently for two reasons. First, the symbiotic association is so well-balanced that the roots of host plants show no damage even when densely infected. Second, the fungi cannot as yet be cultivated in the absence of a living root. Despite these difficulties, there has been important new work that suggests that this symbiotic association can be harnessed to achieve more economical use of costly super phosphate fertilizer and to permit better exploitation of cheaper. less soluble rock phosphate, Mycorrhizal benefits are not limited to improved phosphate uptake in host plants. In legumes, mycorrhzal inoculation has increased nitrogen fixation beyond levels achieved by adding phosphate fertilizer alone. Certain symbiotic associations also increase the host plant's resistance to harmful root fungi. Whether this resistance results from exclusion of harmful fungi through competition for sites, from metabolic change involving antibiotic production, or from increased vigor is undetermined.

单选题This week marks the 10th anniversary of the Alar apple scare, in which many American consumers were driven into a panic following the release of a report by an environmental organization claiming that apples containing the chemical Alar posed a serious health threat to preschoolers. The report was disseminated through a PR (Problem Report) campaign and bypassed any legitimate form of scientific peer review. Introduced to the American public by CBS' "60 Minutes," the unsubstantiated claims in the report led some school districts to remove apples from their school lunch programs and unduly frightened conscientious parents trying to develop good eating habits for their children. Last month, Consumers Union released a report warning consumers of the perils of consuming many fruits and vegetables that frequently contained "unsafe" levels of pesticide residues. This was especially true for children, they claimed. Like its predecessor 10 years earlier, the Consumers Union report received no legitimate scientific peer review and the public's first exposure to it was through news coverage. Not only does such reporting potentially drive children from consuming healthful fruits and vegetables, the conclusions were based on a misleading interpretation of what constitutes a "safe" level of exposure. Briefly, the authors used values known as the "chronic reference doses," set by the U. S. Environmental Protection Agency, as their barometers of safety. Used appropriately, these levels represent the maximum amount of pesticide that could be consumed daily for life without concern. For a 70-year lifetime, for example, consumers would have to ingest this average amount of pesticide every day for more than 25, 000 days. It is clear, as the report points out, that there are days on which kids may be exposed to more; it is also clear that there are many more days when exposure is zero. Had the authors more appropriately calculated the cumulative exposures for which the safety standards are meant to apply, there would have been no risks and no warnings. Parents should feel proud, rather than guilty, of providing fruits and vegetables for their children. It is well established that a diet rich in such foods decreases the risk of heart disease and cancer. Such benefits dramatically overwhelm the theoretical risks of tiny amounts of pesticides in food. So keep serving up the peaches, apples, spinach, squashes, grapes and pears.

单选题{{B}}Passage 2{{/B}} Yeats was beginning to use a vocabulary freshly minted from the treasury of Gaelic literature, and many of the shorter poems in The Countess Kathleen and Various Legends and Lyrics (1892) deal with a mythology Ireland had well nigh forgotten and England never known. For Arthur and his Round Table Yeats substituted the very different Conchubar and his Red Branch Warriors, and Finn and his Fenians. The Red Branch cycle of legends included Fergus, whom Ness had tricked out of his kingdom so that her son Conchubar could rule over Ulster in his stead, and in Fergus and the Druid Yeats makes him avid for dreaming wisdom. Fergus was the unwitting agent of the doom of the Sons of Usna, Naoise the lover of Deirdre and his brothers Ardan and Ainle, who had accompanied the lovers to Scotland when they fled from Conchubar's wrath, for Deirdre was Conchubar's intended bride. Fergus had persuaded them to return against the wishes of Deirdre and had been tricked out of acting as their safe conduct. He joined with Maeve, Queen of Connaught, after this, in her raid on Ulster, in which Cuehulain achieved his great fame as Ulster's champion. Cuehulain is the Achilles of the Irish Saga, and he appears throughout Yeats's plays and poems, as warrior, as husband of Emer, as lover of Eithne Inguba, and of Aoife, as the unknowing killer of his own son and finally as victim of the sea.
