单选题 Civil-Liberties advocates reeling from the recent revelations on surveillance had something else to worry about last week: the privacy of the billions of search queries made on sites like Google, AOL, Yahoo and Microsoft. As part of a long-running court case, the government has asked those companies to turn over information on its users' search behavior. All but Google have handed over data, and now the Department of Justice (DOJ) has moved to compel the search giant to turn over the goods. What makes this case different is that the intended use of the information is not related to national security, but the government's continuing attempt to police Internet pornography. In 1998, Congress passed the Child Online Protection Act (COPA), but courts have blocked its implementation due to First Amendment concerns. In its appeal, the DOJ wants to prove how easy it is to inadvertently stumble upon pore. In order to conduct a controlled experiment—to be performed by a UC Berkeley professor of statistics—the DOJ wants to use a large sample of actual search terms from the different search engines. It would then use those terms to do its own searches, employing the different kinds of filters each search engine offers, in an attempt to quantify how often "material that is harmful to minors" might appear. Google contends that since it is not a party to the case, the government has not right to demand its proprietary information to perform its test. "We intend to resist their motion vigorously," said Google attorney Nicole Wong. DOJ spokesperson Charles Miller says that the government is requesting only the actual search terms, and not anything that would link the queries to those who made them. (The DOJ is also demanding a list of a million Web sites that Google indexes to determine the degree to which objectionable sites are searched. ) Originally, the government asked for a treasure trove of all searches made in June and July 2005; the request has been scaled back to one week's worth of search queries. One oddity about the DOJ's strategy is that the experiment could conceivably sink its own case. If the built-in filters that each search engine provides are effective in blocking porn sites, the government will have wound up proving what the opposition has said all along—you don't need to suppress speech to protect minors on the Net."We think that our filtering technology does a good job protecting minors from inadvertently seeing adult content," says Ramez Naam, group program manager of MSN Search. Though the government intends to use these data specifically for its COPA-related test, it's possible that the information could lead to further investigations and, perhaps, subpoenas to find out who was doing the searching. "What if certain search terms indicated that people were contemplating terrorist actions or other criminal activities?" Says the DOJ's Miller, "I'm assuming that if something raised alarms, we would hand it over to the proper authorities." Privacy advocates fear that if the government request is upheld, it will open the door to further government examination of search behavior. One solution would be for Google to stop storing the information, but the company hopes to eventually use the personal information of consenting customers to improve search performance. " Search is a window into people's personalities," says Kurt Opsahl, an Electronic Frontier Foundation attorney. "They should be able to take advantage of the Internet without worrying about Big Brother looking over their shoulders."

单选题Passage 3 It can be argued that much consumer dissatisfaction with marketing strategies arises from an inability to aim advertising at only the likely buyers of a given product. There are three groups of consumers who are affected by the marketing process. First, there is the market segment—people who need the commodity in question. Second, there is the program target—people in the market segment with the "best fit" characteristics for a specific product. Lots of people may need trousers, but only a few qualify as likely buyers of very expensive designer trousers. Finally, there is the program audience-all people who are actually exposed to the marketing program without regard to whether they need or want the product. These three groups are rarely identical. An exception occurs in cases where customers for a particular industrial product may be few and easily identifiable. Such customers, all sharing a particular need, are likely to form a meaningful target, for example, all companies with a particular application of the product in question, such as high-speed fillers of bottles at breweries. In such circumstances, direct selling (marketing that reaches only the program target) is likely to be economically justified, and highly specialized trade media exist to expose members of the program target—and only members of the program target—to the marketing program. Most consumer-goods markets are significantly different. Typically, there are many rather than few potential customers. Each represents a relatively small percentage of potential sales. Rarely do members of a particular market segment group themselves neatly into a meaningful program target. There are substantial differences among consumers with similar demographic characteristics. Even with all the past decade's advances in information technology, direct selling of consumer goods is rare, and mass marketing—a marketing approach that aims at a wide audience—remains the only economically feasible mode. Unfortunately, there are few media that allow the marketer to direct a marketing program exclusively to the program target. Inevitably, people get exposed to a great deal of marketing for products in which they have no interest and so they become annoyed.

单选题"Masterpieces are dumb," wrote Flaubert, "They have a tranquil aspect like the very products of nature, like large animals and mountains." He might have been thinking of War and Peace, that vast, silent work, unfathomable and simple, provoking endless questions through the majesty of its being. Tolstoi's simplicity is "overpowering," says the critic Bayley, "disconcerting," because it comes from "his casual assumption that the world is as he sees it. " Like other nineteenth-century Russian writers he is "impressive" because he "means what he says," but he stands apart from all others and from most Western writers in his identity with life, which is so complete as to make us forget he is an artist. He is the center of his work, but his egocentricity is of a special kind. Goethe, for example, says Bayley, "cared for nothing but himself. Tolstoi was nothing but himself. " For all his varied modes of writing and the multiplicity of characters in his fiction, Tolstoi and his work are of a piece. The famous "conversion" of his middle years, movingly recounted in his Confession, was a culmination of his early spiritual life, not a departure from it. The apparently fundamental changes that led from epic narrative to dogmatic parable, from a joyous, buoyant attitude toward life to pessimism and cynicism, from War and Peace to The Kreutzer Sonata, came from the same restless, impressionable depths of an independent spirit yearning to get at the truth of its experience. "Truth is my hero," wrote Tolstoi in his youth, reporting the fighting in Sebastopol. Truth remained his hero — his own, not others', truth. Others were awed by Napoleon, believed that a single man could change the destinies of nations, adhered to meaningless rituals, formed their tastes on established canons of art. Tolstoi reversed all preconceptions; and in every reversal he overthrew the "system," the "machine," the externally ordained belief, the conventional behavior in favor of unsystematic, impulsive life, of inward motivation and the solutions of independent thought. In his work the artificial and the genuine are always exhibited in dramatic opposition: the supposedly great Napoleon and the truly great, ignored little Captain Tushin, or Nicholas Rostov's actual experience in battle and his later account of it. The simple is always pitted against the elaborate, knowledge gained from observation against assertions of borrowed faiths. Tolstoi's magical simplicity is a product of these tensions; his work is a record of the questions he put to himself and of the answers he found in his search. The greatest characters of his fiction exemplify this search, and their happiness depends on the measure of their answers. Tolstoi wanted happiness, but only hard-won happiness, that emotional fulfillment and intellectual clarity which could come only as the prize of all-consuming effort. He scorned lesser satisfactions.
