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 Term 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) 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{{B}}Passage Two{{/B}} Henry Ford, the famous U.S. inventor and car manufacturer, once said, "The business of America is business." By this he meant that the U.S. way of life is based on the values of the business world. Few would argue with Ford's statement. A brief glimpse at a daffy newspaper vividly shows how much people in the United States think about business. For example, nearly every newspaper has a business section, in which the deals and projects, finances and management, stock prices and labor problems of corporations are reported daily. In addition, business news can appear in every other section. Most national news has an important financial aspect to it. Welfare, foreign aid, the federal budget, and the policies of the Federal Reserve Bank are all heavily affected by business. Moreover, business news appears in some of the unlikeliest places. The world of arts and entertainment is often referred to as "the entertainment industry" or "show business". The positive side of Henry Ford's statement can be seen in the prosperity that business has brought to U.S. life. One of the most important reasons so many people from all over the world come to live in the United States is the dream of a better job. Jobs are produced in abundance because the U.S. economic system is driven by competition. People believe that this system creates more wealth, more jobs, and a materially better way of life. The negative side of Henry Ford's statement, however, can be seen when the word business is taken to mean big business. And the term big business—referring to the biggest companies—is seen in opposition to labor. Throughout U.S. history working people have had to fight hard for higher wages, better working conditions, and the fight to form unions. Today, many of the old labor disputes are over, but there is still some employee anxiety. Downsizing—the driving away of thousands of workers to keep expenses low and profits high—createsfeelings of insecurity for many.

单选题{{B}}Passage Three{{/B}} When 23-year-old Eric Atienza graduated from college last Year, he didn't have a job. Not wanting to give up his apartment and move back with his parents, he did what many young Americans are doing: he signed up with a temp agency, which places workers on short-term jobs. Temporary workers such as Atienza comprise 20 per cent of the U.S. workforce. In 1985, 417,000 workers were classified as temporary help. In 2005, there are more than 2.5 million, according to Labour Department data. Using temporary workers allows companies to increase or decrease the number of staff as their workloads change. It also allows companies to avoid the costs involved in hiring and firing long-term employees. Many temp agency owners and career specialists say temping is a good way for recent graduates to get experience. "Short-term jobs let graduates try out different companies to find the best fit," said Pegi Wheatley, owner of McCall Staffing, a San Francisco temp agency. But things don't always work out that way. "when I started temping, I had this notion that a temporary job could turn full-time. I worked for a friend of mine, but that didn't happen for me," said Atienza, who quickly became bored with his office work. Atienza stayed with the temp agency because he could earn U.S.＄10 an hour doing office work. Other short-term jobs, such as working as a store clerk in a cafe, pay about U.S.＄7. But there were trade-offs for the higher pay. Because in the U.S., health insurance is provided through employer, most temps are not eligible for workplace health benefits. Atienza ran the risk that an accident or illness would land him in the hospital with no way to pay the bill. Other drawbacks, though less serious, still mean that temping for most graduates is exactly what its name implies- a temporary choice. Instability, gaps between contracts, lack of vacation time and isolation from other employees are often-cited negatives. "Temping gave me the time to figure out what I wanted to do, because I could pay off my bills. But none of that came from the jobs themselves," said Atienza, who quit temping last month in favor of a full-time job.

单选题{{B}}Passage Four{{/B}} A nocturnal(夜间活动的)moth has become the first animal known to see colours in the dead of night. The moth uses this visual talent to find yellow, nectar-packed flowers in the dark, but the finding suggests that other, species also use colour vision at night. Nocturnal moths were thought to find flowers by looking for bright petals against a darker, leafy background. This difference in brightness explains why a yellow flower stands out from green leaves on a black and white photo. To test this idea, researchers at Lund University in Sweden trained nocturnal elephant hawkmoths(豆天蛾)to pick out yellow or blue artificial flowers from eight other flowers of varying shades of grey. They then made moths perform the trick in conditions as dark as a starry but moonless night. The researchers expected the moths to do badly, but to their surprise the insects picked the correct flower 90 per cent of the time. But the moths could not distinguish between lighter and darker shades of a coloured flower, even though they could still tell both from grey. "This tells us it's not a brightness-related cue,” says Almut Kelber, the sensory biologist leading the Lund team. "They could only have used the spectral(光谱的)composition of the signals—which we call colour." The moths use three separate colour receptors: blue, green and ultraviolet. At night, that leaves so little light per receptor that the insects should be almost blind. But hawkmoths have a host of adaptations to compensate. One is a mirror-like structure at the base of the eye, which reflects the light across the photoreceptors for a second time. The structure of the compound eye also allows each facet to supplement the light that strikes it with light from as many as 600 others. Kelber suspects that many other insects, and some higher animals, also use colour vision at night. She plans to look for the ability in nocturnal frogs and toads that use colour to choose their mate. "Why not? she asks. "At night there are just as many colours as during the day."
