问答题{{U}}Quantum mechanics is a highly successful theory: it supplies methods for accurately calculating the results of diverse experiments, especially with minute particles.{{/U}} The predictions of quantum mechanics, however, give only the probability of an event, not a deterministic statement of whether or not the event will occur. {{U}}Because of this probabilism, Einstein remained strongly dissatisfied with the theory throughout his life,{{/U}} though he did not maintain that quantum mechanics is wrong. Rather, he held that it is incomplete: in quantum mechanics the motion of a particle must be described in terms of probabilities, he argued, only because some parameters that determine the motion have not been specified. If these hypothetical "hidden parameters" were known, a fully deterministic trajectory could be defined. Significantly, this hidden-parameter quantum theory leads to experimental predictions different from those of traditional quantum mechanics. Einstein's ideas have been tested by experiments performed since his death, and as most of these experiments support traditional quantum mechanics, {{U}}Einstein's approach is almost certainly erroneous.{{/U}}

问答题{{U}}Paule Marshall's Brown Girl, Brownstones (1959) was a landmark in the depiction of female characters in Black American literature.{{/U}} Marshall avoided the oppressed and tragic heroine in conflict with White society that had been typical of the protest novels of the early twentieth century. Like her immediate predecessors, Zora Neale Hurston and Gwendolyn Brooks, she focused her novel on an ordinary Black woman's search for identity within the context of a Black community. But Marshall extended the analysis of Black female characters begun by Hurston and Brooks by depicting her heroine's development in terms of the relationship between her Barbadian American parents, and by exploring how male and female roles were defined by their immigrant culture, which in turn was influenced by the materialism of White America. By placing characters within a wider cultural context, Marshall attacked racial and sexual stereotypes and paved the way for explorations of race, class, and gender in the novels of the 1970's.

问答题{{U}}A long-held view of the history of the English colonies that became the United States has been that England's policy toward these colonies before 1763 was dictated by commercial interests and that a change to a more imperial policy,{{/U}} dominated by expansionist militarist objectives, generated the tensions that ultimately led to the American Revolution. {{U}}In a recent study, Stephen Saunders Webb has presented a formidable challenge to this view.{{/U}} According to Webb, England already had a military imperial policy for more than a century before the American Revolution. He sees Charles II, the English monarch between 1660 and 1685, as the proper successor of the Tudor monarchs of the sixteenth century and of Oliver Cromwell, all of whom were bent on extending centralized executive power over England's possessions through the use of what Webb calls "garrison government". Garrison government allowed the colonists a legislative assembly, but real authority, in Webb's view, belonged to the colonial governor, who was appointed by the king and supported by the "garrison", that is, by the local contingent of English troops under the colonial governor's command. {{U}}According to Webb, the purpose of garrison government was to provide military support for a royal policy designed to limit the power of the upper classes in the American colonies.{{/U}} Webb argues that the colonial legislative assemblies represented the interests not of the common people but of the colonial upper classes, a coalition of merchants and nobility who favored self-rule and sought to elevate legislative authority at the expense of the executive. It was, according to Webb, the colonial governors who favored the small farmer, opposed the plantation system, and tried through taxation to break up large holdings of land. Backed by the military presence of the garrison, these governors tried to prevent the gentry and merchants, allied in the colonial assemblies, from transforming colonial America into a capitalistic oligarchy. {{U}}Webb's study illuminates the political alignments that existed in the colonies in the century. prior to the American Revolution, but his view of the crown's use of the military as an instrument of colonial policy is not entirely convincing.{{/U}} England during the seventeenth century was not noted for its military achievements. Cromwell did mount England's most ambitious overseas military expedition in more than a century, but it proved to be an utter failure. Under Charles II, the English army was too small to be a major instrument of government. Not until the war with France in 1697 did William III persuade Parliament to create a professional standing army, and Parliaments price for doing so was to keep the army under tight legislative control. {{U}}While it may be true that the crown attempted to curtail the power of the colonial upper classes, it is hard to imagine how the English army during the seventeenth century could have provided significant military support for such a policy.{{/U}}

问答题{{U}}Although the hormone adrenaline is known to regulate memory storage, it does not pass from the blood into brain cells.{{/U}} We are faced with an apparent paradox: how can a hormone that does not act directly on the brain have such a large effect on brain function? Recently, we tested the possibility that one of the hormone's actions outside the brain might be responsible. Since one consequence of adrenaline release in an animal is an increase in blood glucose levels, we examined the effects of glucose on memory in rats. We found that glucose injected immediately after training enhances memory tested the next day. Additional evidence was provided by negative findings: drugs called adrenergic antagonists, which block peripheral adrenaline receptors, disrupted adrenaline's ability to regulate memory but did not affect memory enhancements produced by glucose that was not stimulated by adrenaline. These results are as they should be if adrenaline affects memory modulation by increasing blood glucose levels.

问答题(1) Biologists have long maintained that two groups of pinnipeds, sea lions and walruses, are descended from a terrestrial bearlike animal, whereas the remaining group, seals, shares an ancestor with weasels. (2) {{U}}But the recent discovery of detailed similarities in the skeletal structure of the flippers in all three groups undermines the attempt to explain away superficial resemblance as due to convergent evolution—the independent development of similarities between unrelated groups in response to similar environmental pressures.{{/U}} (3) Flippers may indeed be a necessaryresponse to aquatic life; turtles, whales, and dugongs also have them. (4) But the common detailed design found among the pinnipeds probably indicates a common ancestor. (5) Moreover, walruses and seals drive themselves through the water with thrusts of their hind flippers, but sea lions use their front flippers. (6) If anatomical similarity in the flippers resulted from similar environmental pressures, as posited by the convergent evolution theory, one would expect walruses and seals, but not seals and sea lions, to have similar flippers. Select the sentence in the passage in which the author shows that the implication of the common view is contradicted by a new finding.

问答题{{U}}Of Homer's two epic poems, the Odyssey has always been more popular than the Iliad,{{/U}} perhaps because it includes more features of mythology that are accessible to readers. Its subject (to use Maynard Mack's categories) {{U}}is "life-as-spectacle", for readers, diverted by its various incidents, observe its hero Odysseus primarily from without;{{/U}} the tragic Iliad, however, presents "life-as-experience": readers are asked to identify with the mind of Achilles, whose motivations render him a not particularly likable hero. In addition, the Iliad, more than the Odyssey, suggests the complexity of the gods' involvement in human actions, and to the extent that modem readers find this complexity a needless complication, {{U}}the Iliad is less satisfying than the Odyssey, with its simpler scheme of divine justice.{{/U}} Finally, since the Iliad presents a historically verifiable action, Troy's siege, {{U}}the poem raises historical questions that are absent from the Odyssey's blithely imaginative world.{{/U}}
