单选题The sources of anti-Christian feeling were many and complex. On the more intangible side, there was a general pique against the unwanted intrusion of the Western countries; there was an understandable tendency to seek an external scapegoat for internal disorders only tangentially attributable to the West and perhaps most important, there was a virile tradition of ethnocentrism, vented long before against Indian Buddhism, which, since the seventeenth century, focused on Western Christianity. Accordingly, even before the missionary movement really got under may in the mid-nineteenth century, it was already at a disadvantage. After 1860, as missionary activity in the hinterland expanded, it quickly became apparent that in addition to the intangibles, numerous tangible grounds for Chinese hostility abounded. In part, the very presence of the missionary evoked attack. They were, after all, the first foreigners to leave the treaty ports and venture into the interior, and for a ling time they were virtually the only foreigners whose quotidian labors carried them to the farthest reaches of the Chinese empire. For many of the indigenous population, therefore, the missionary stood as a uniquely visible symbol against which opposition to foreign intrusion could be vented. In part, too, the missionary was attacked because the manner in which he made his presence felt after 1860 seemed almost calculated to offend. By indignantly waging battles against the notion that China was the sole fountainhead of civilization and, more particularly, by his assault on many facets of Chinese culture per se, the missionary directly undermined the cultural hegemony of the gentry class. Also, in countless ways, he posed a threat to the gentry's traditional monopoly of social leadership. Missionaries, particularly Catholics, frequently assumed the garb of the Confucian literati. They were only persons at the local level, aside from the gentry, who were permitted to communicate with the authorities as social equals. And they enjoyed an extraterritorial status in the interior that gave them greater immunity to Chinese law than had ever been possessed by the gentry. Although it was the avowed policy of the Chinese government after 1860 that the new treaties were to be strictly adhered to, in practice implementation depended on the wholehearted accord of provincial authorities. There is abundant evidence that cooperation was dilatory. At the root of this lay the interactive nature of ruler and ruled. In a severely understaffed bureaucracy that ruled as much by suasion as by might, the official almost always a stranger in the locality of his service, depended on the active cooperation of the local gentry class. Energetic attempts to implement treaty provisions concerning missionary activities, in direct defiance of gentry sentiment, ran the risk of alienating this class and destroying future effectiveness.

单选题Which of the following criticisms is often made of the Sapir-Whorf Hypothesis?

单选题" I have great confidence that by the end of the decade we'll know in vast detail how cancer cells arise," says microbiologist Robert Weinberg, an expert on cancer. " But," he cautions, "some people may have the idea that once one understands the causes, the cure will rapidly follow. Consider Pasteur. He discovered the causes of many kinds of infections, but it was fifty or sixty years before cures were available. " This year, 50 percent of the 910, 000 people who suffer from cancer will survive at least five years. In the year 2000, the National Cancer Institute estimates, that figure will be 75 percent. For some skin cancers, the five-year survival rate is as high as 90 percent. But other survival statistics are still discouraging — 13 percent for lung cancer, and 2 percent for cancer of the pancreas. With as many as 120 varieties in existence, discovering how cancer works is not easy. The researchers made great progress in the early 1970s, when they discovered that oncogenes, which are cancer-causing genes, are inactive in normal cells. Anything from cosmic rays to radiation to diet may activate a dormant oncogene, but how remains unknown. If several oncogenes are driven into action, the cell, unable to turn them off, becomes cancerous. The exact mechanisms involved are still mysterious, but the likelihood that many cancers are initiated at the level of genes suggests that we will never prevent all cancers. " Changes are a normal part of the evolutionary process," says oncologist William Hayward. Environmental factors can never be totally eliminated; as Hayward points out, "We can't prepare a medicine against cosmic rays. " The prospects for cure, though still distant, are brighter. "First, we need to understand how the normal cell controls itself. Second, we have to determine whether there are a limited number of genes in cells which are always responsible for at least part of the trouble. If we can understand how cancer works, we can counteract its action. "

单选题{{B}}Passage Three{{/B}} Sometimes it's just hard to choose. You're in a restaurant and the waiter has his pen at the ready. As you hesitate, he gradually begins to take a close interest in the ceiling, his fingernails, then in your dining partner. Each dish on the menu becomes a blur as you roll your eyes up and down in a growing panic. Finally, you desperately opt for something that turns out to be what you hate. It seems that we need devices to protect us from our hopelessness at deciding between 57 barely differentiated varieties of stuff—be they TV channels, gourmet coffee, downloadable ring tones, or perhaps, ultimately even interchangeable lovers. This thought is opposed to our government's philosophy, which suggests that greater choice over railways, electricity suppliers and education will make us happy. In my experience, they do anything but. Perhaps the happiest people are those who do not have much choice and aren't confronted by the misery of endless choice. True, that misery may not be obvious to people who don't have a variety of luxuries. If you live in Madagascar, say, where average life expectancy is below 40 and they don't have digital TV or Starbucks, you might not be impressed by the anxiety and perpetual stress our decision-making paralysis causes. Choice wasn't supposed to make people miserable. It was supposed to be the hallmark of self-determination that we so cherish in capitalist western society. But it obviously isn't: ever more choice increases the feeling of missed opportunities, and this leads to self-blame when choices fail to meet expectations. What is to be done? A new book by an American social scientist, Barry Schwartz, called The Paradox of Choice, suggests that reducing choices can limit anxiety. Schwartz offers a self-help guide to good decision making that helps us to limit our choices to a manageable number, and ultimately derive greater satisfaction from the choices we make. This is a capitalist response to a capitalist problem. But once you realize that your Schwartzian filters are depriving you of something you might have found enjoyable, you will experience the same anxiety as before, worrying that you made the wrong decision in drawing up your choice-limiting filters. Arguably, we will always be doomed to buyers' remorse and the misery it entails. The problem of choice is perhaps more difficult than Schwartz allows.
