单选题Attacking an increasingly popular Internet business practice, a consumer watchdog group Monday filed a complaint with the Federal Trade Commission, asserting that many online search engines are concealing the impact special fees have on search results by Internet users. Commercial Alert, a 3-year-old group founded by consumer activist Ralph Nader, asked the FTC to investigate whether eight of the Web's largest search engines are violating federal laws against deceptive advertising. The group said that the search engines are abandoning objective formulas, to determine the order of their listed results and selling the top spots to the highest bidders without making adequate disclosures to Web surfers. The complaint touches a hot-button issue affecting tens of millions of people who submit search queries each day. With more than 2 billion pages and more than 14 billion hyperlinks on the Web, search requests rank as the second most popular online activity after E-mail. The eight search engines named in Commercial Alert's complaint are. MSN, owned by Microsoft; Netscape, owned by AOL Time Warner; Directhit, owned by Ask Jeeves; HotBot and Lycos, both owned by Terra Lycos; Altavista, owned by CMGI; LookSmart, owned by LookSmart; and Iwon, owned by a privately held company operating under the same name. Portland, Ore. -based Commercial Alert could have named more search engines in its complaint, but focused on the biggest sites that are auctioning off spots in their results, said Gary Ruskin, the group's executive director. "Search engines have become central in the quest for learning and knowledge in our society. The ability to skew (扭曲) the results in favor of hucksters (小贩) without telling consumers is a serious problem," Ruskin said. By late Monday afternoon, three of the search engines had responded to The Associated Press' inquiries about the complaint. Two, LookSmart and AltaVista, denied the charges. Microsoft spokesman Matt Pilla said MSN is delivering" compelling search results that people want." The FTC had no comment about the complaint Monday. The complaint takes aim at the new business plans embraced by more search engines as they try to cash in on their pivotal (关键的) role as Web guides and reverse a steady stream of losses. To boost revenue, search engines in the past year have been accepting payments from businesses interested in receiving a higher ranking in certain categories or ensuring that their sites are reviewed more frequently.

单选题Passage 3 As a wise man once said, we are all ultimately alone. But an increasing number of Europeans are choosing to be so at an ever earlier age. This isn't the stuff of gloomy philosophical contemplations, but a fact of Europe's new economic landscape, embraced by sociologists, real-estate developers and ad executives alike. The shift away from family life to solo lifestyle, observes a French sociologist, is part of the "irresistible momentum of individualism" over the last century. The communications revolution, the shift from a business culture of stability to one of mobility and the mass entry of women into the workforce have greatly wreaked havoc on (扰乱) European's private lives. Europe's new economic climate has largely fostered the trend toward independence. The current generation of home-aloners came of age during Europe's shift from social democracy to the sharper, more individualistic climate of American style capitalism. Raised in an era of privatization and increased consumer choice, today's tech-savvy (精通技术的) workers have embraced a free market in love as well as economics. Modem Europeans are rich enough to afford to live alone, and temperamentally independent enough to want to do so. Once upon a time, people who lived alone tended to be those on either side of marriage-twenty something professionals or widowed senior citizens. While pensioners, particularly elderly women, make up a large proportion of those living alone, the newest crop of singles are high earners in their 30s and 40s who increasingly view living alone as a lifestyle choice. Living alone was conceived to be negative, dark and cold, while being together suggested warmth and light. But then came along the idea of singles. They were young, beautiful, strong! Now, young people want to live alone. The booming economy means people are working harder than ever. And that doesn't leave much room for relationships. Pimpi Arroyo, a 35-year-old composer who lives alone in a house in Paris, says he hasn't got time to get lonely because he has too much work. "I have deadlines which would make life with someone else fairly difficult." Only an Ideal Woman would make him change his lifestyle, he says. Kaufmann, author of a recent book called "The Single Woman and Prince Charming," thinks this fierce new individualism means that people expect more and more of mates, so relationships don't last long-- if they start at all. Eppendorf, a blond Berliner with a deep tan, teaches grade school in the morning. In the afternoon she sunbathes or sleeps, resting up for going dancing. Just shy of 50, she says she'd never have wanted to do what her mother did-- give up a career to raise a family. Instead, "I've always done what I wanted to do: live a self-determined life./

单选题Rocks which have solidified directly from molten materials are called igneous rocks. Igneous rocks are commonly referred to as primary rocks because they are the original source of material found in sedimentaries and metamorphics. Igneous rocks compose the greater part of the earth's crust, but they are generally covered at the surface by a relatively thin layer of sedimentary or metamorphic rocks. Igneous rocks are distinguished by the following characteristics: (1) they contain no fossils; (2) they have no regular arrangement of layers; and (3) they are nearly always made up of crystals.Sedimentary rocks are composed largely of minute fragments derived from the disintegration of existing rocks and in some instances from the remains of animals. As sediments are transported, individual fragments are assorted according to size. Distinct layers of such sediments as gravels, sand, and clay build up, as they are deposited by water and occasionally wind. These sediments vary in size with the material and the power of the eroding agent. Sedimentary materials are laid clown in layers called strata. When sediments harden into sedimentary rocks, the names applied to them change to indicate the change in physical state. Thus, small stones and gravel cemented together are known as conglomerates; cemented sand becomes sandstone; and hardened clay becomes shale. In addition to these, other sedimentary rocks such as limestone frequently result from the deposition of dissolved material. The ingredient parts are normally precipitated by organic substances, such as shells of clams or hard skeletons of other marine life. Both igneous and sedimentary rocks may be changed by pressure, heat, solution, or cementing action. When individual grains from existing rocks tend to deform and interlock, they are called metamorphic rocks. For example, granite, an igneous rock, may be metamorphosed into a gneiss or a schist. Limestone, a sedimentary rock, when subjected to heat and pressure may become marble, a metamorphic rock. Shale under pressure becomes slate.
