单选题This year the combined advertising revenues of Google and Yahoo! will rival the combined prime-time ad revenues of America's three big television networks, ABC, CBS and NBC, predicts Advertising Age. 41. ______. And this week online advertising made another leap forward. The latest innovation comes from Google, which has begun testing a new auction-based service for display advertising. It already provides a service called AdSense. It works rather like an advertising agency, automatically placing sponsored links and other ads on third-party websites. Google then splits the revenue with the owners of those websites, who can range from multinationals to individuals publishing blogs, as online journals are known. Google's new services extend AdSense in three ways. 42. ______ This provides both more flexibility and control, says Patrick Keane, Google's head of sales strategy. Companies trying to raise awareness of a brand often want a high level of control over where their ads appear. The second change involves pricing. 43. ______. Click-through marketing tends to be aimed at people who already know they want to buy something and are searching for product and price information, whereas display advertising is more often used to persuade people to buy things in the first instance. The third change is that Google will now offer animated ads--but nothing too flashy or annoying, insists Mr. Keane. Google has long been extremely conservative about the use of advertising; it still plans to use only small, text-based ads on its own search sites. 44. ______. This could fuel online ad-growth even further. Worldwide ad revenue on the internet grew by 21% in 2004, and it is expected to continue at that pace for the next few years, says ZenithOptimedia, a research firm. As Google and Yahoo! are two of the most widely visited sites, this greatly benefits them. 45. ______. Terry Semel, Yahoo!' s chief executive, believes there is a lot more growth to come as companies become more familiar with online advertising. Other innovations in online marketing are said to be in the pipeline. Local search and its associated advertising opportunities are one huge growth area. This week, Yahoo! appointed another top executive to its media group, fuelling industry speculation that the website may start to produce its own entertainment content. Television stations would then have a lot more to worry about than just losing ad revenue to the internet.[A] Instead of Google's software analyzing third-party websites to determine from their content what relevant ads to place on them, advertisers will instead be able to select the specific sites where they want their ads to appear.[B] Google recently announced a net profit of $ 369m in its first quarter from revenue that soared to $1.3 billion, up 93% compared with the same period a year earlier. Yahoo!'s first-quarter net profits more than doubled to $ 205m on revenue of $1.2 billion, up 55% from a year earlier.[C] Many big firms still allocate only 2-4% of their marketing budgets to the internet, although it represents about 15% of consumers' media consumption--a share that is growing. Many young people already spend more time online than they do watching TV.[D] It will, says the trade magazine, represent a "watershed moment" in the evolution of the internet as an advertising medium. A 30-second prime-time TV ad was once considered the most effective--and the most expensive--form of advertising. But that was before the internet got going.[E] But many of its AdSense partners might well be tempted by the prospect of earning a share of revenue from display and animated ads too, especially as such ads are likely to be more appealing to some of the big-brand advertisers.[F] Sites such as eBay, the leading online auctioneer, and Craigslist, which hosts local sites, are soaking up large amounts of spending that might otherwise have gone on classified advertising-and for everything from used cars to job vacancies. Yahoo! is expanding heavily into entertainment, with film and video clips providing another avenue for advertisers.[G] Potential internet advertisers must bid for their ad to appear on a "cost-per-thousand" (known as CPM) basis. CPM bids will have to compete against rival bids for the same ad space from those wanting to pay on a "cost-per-click" basis, the way search terms are presently sold.

单选题Potential AIDS victims who refuse to be tested for the disease and then defend their right to remain ignorant about whether they carry the virus are entitled to that fight. But ignorance cannot be used to rationalize irresponsibility. Nowhere in their argument is their concern about how such ignorance might endanger public health by exposing others to the virus. All disease is an outrage, and disease that affects the young and healthy seems particularly outrageous. When a disease selectively attacks the socially disadvantaged, such as homosexuals and drug abusers, it seems an injustice beyond rationalization. Such is the case with acquired immune deficiency syndrome. Decent people are offended by this unfairness and in the name of benevolence have been driven to do morally irresponsible things such as denying the unpleasant facts of the disease, out of compassion for the victims. We cannot distort the facts to comfort the afflicted when such confusion compounds the tragedy. Some crucial facts: AIDS is a communicable disease. The percentage of those infected with the AIDS virus who will eventually contract the disease is unknown, but that percentage rises with each new estimate. The disease so far has been 100 potential. The latency period between the time the virus is acquired and the disease develops is also unknown. We now have teats for the presence of the virus that is as efficient and reliable as almost any diagnostic test in medicine. An individual who tests positive can be presumed with near-certainty to carry the virus, whether he has the disease or not. To state that the test for AIDS is "ambiguous", as a clergyman recently in public, is a misstatement and an immoral act. To state that the test does not directly indicate the presence of the virus is a half-truth that misleads and an immoral act. The test correlates so consistently with the presence of the virus in bacteria cultures as to be considered I00 percent certain by experts. Everyone who tests positive must understand that he is a potential vector for the AIDS virus and has a moral duty and responsibility to prevent others from contamination. We are not just dealing with the protection of the innocent but with an essential step to contain the spread of an epidemic as horrible as any that has befallen modern man. We must do everything in our power to keep this still, untreatable disease from becoming pandemic. It may seem unfair to burden the tragic victims with concern for the welfare of others. But moral responsibility is not a luxury of the fortunate, and evil actions committed in despair cannot be condemned out of pity. It is morally wrong for a healthy individual who tests positive for AIDS to be involved with anyone except under the strict precautions now defined as safe sex. It is morally wrong for someone in a high-risk population who refuses to test himself to do other than to assume that he tests positive. It is morally wrong for those who, out of sympathy for the heartbreaking victims of this epidemic, as though well wishing and platitudes(老生常谈) about the ambiguities of the disease are necessary in order to comfort the victims while 'they contribute to enlarging the number of those victims. Moral responsibility is the burden of the sick as well as the healthy.

单选题{{B}}Text 4{{/B}} Should anyone much care whether an American boy living overseas gets six vicious thwacks on his backside? So much has been argued, rejoined and rehashed about the case of Michael Fay, an 18-year-old convicted of vandalism and sentenced to a caning in Singapore, that an otherwise sorry little episode has shaded into a certified International Incident, complete with intercessions by the U. S. head of state. An affair has outraged American libertarians even as it has animated a general debate about morality East and West and the proper functioning of U.S. law and order. Which, to all appearances, is what Singapore wanted. The question of whether anyone should care about Michael Fay is idle: though Singapore officials profess shock at the attention his case had drawn, they know Americans care deeply about the many sides of this issue. Does a teenager convicted of spraying cars with easily removable paint deserve half a dozen powerful strokes? At what point does swift, sure punishment become torture? By what moral authority can America, with its high rates of lawlessness and license, preach of a safe society about human rights? The caning sentence has concentrated minds wondrously on an already lively domestic debate over what constitutes a due balance between individual and majority rights. Too bad Michael Fay has become a focus for this discussion. Not only does he seem destined to be pummeled and immobilized, but the use of Singapore as a standard for judging any other society, let alone the {{U}}cacophonous{{/U}} U. S. , is fairly worthless. To begin with, Singapore is an offshore republic that tightly limits immigration. Imagine crime-ridden LOS Angeles, to which Singapore is sometimes contrasted, with hardly any inflow of the hard-luck, often desperate fortune seekers who flock to big cities. Even without its government's disciplinary measures, Singapore more than plausibly would be much the same as it is now. An academic commonplace today is that the major factor determining social peace and prosperity is culture--a sense of common identity, tradition and values. Unlike Singapore, though, the U. S. today is a nation in search of a common culture, trying to be a universal society that assimilates the traditions of people from all over the world. Efforts to safeguard minority as well as individual rights have produced a gridlock in the justice system. Its troubles stem more from the decay of family life than from any government failures. Few societies can afford to look on complacently. As travel eases and cultures intermix, the American experience is becoming the world's. The circumstances of this affair--evidently no Singaporean has ever been punished under the Vandalism Act for defacing private property--suggest that Singapore has used Fay as an unwilling point man in a growing quarrel between East and West about human rights.

单选题Ever since they were first staged in 19th century Europe, world's fairs have enabled people from around the globe to visit wondrous pavilions where they can discover distant lands and new technologies. The 2006 world's fair is no exception, but it also has a decidedly new-era twist: the whole event happens in cyberspace. A nonprofit project dreamed up by Americans Carl Malamud, a computer consultant, and Vinton Cerf, and Internet pioneer and telecommunications company Vice president, the Internet 2006 World Exposition is a digital work in progress, a multi-chambered forum that cybernauts can help build and renovate throughout the year--and perhaps long after the fair's official close in December. While high-tech pavilions set up by sponsoring corporations are featured prominently, as in real fairs, this virtual exposition is closer in spirit and reality to a vast bustling bazaar, a marketplace for the talents and offerings of thousands of individuals and small groups. Anyone with a computer and a modem can not only "attend" but also participate as an exhibitor by creating an individual multimedia Website. Getting the fair up and running was by no means easy. Malamud, 36, spent the past year shuttling among 30 countries, lobbying companies that initially dismissed the project as unwieldy and unworkable. While some nations immediately supported the idea, others completely missed the point of Malamud's vision: to make the fair a public-works project that focuses on what the Internet can offer expert or novice. Once grass-roots groups started backing the project, though, businesses were not far behind. By donating equipment and services, these companies will gain access to millions of potential consumers eager to see the firms' latest technologies. Since the exposition's Jan. 1 launch, as many as 40,000 visitors each day from more than 40 countries have tried the major Websites. Most virtual visitors log on from the U. S and Japan, but the United Arab Emirates, Sweden, Singapore and Estonia have been represented. Comments logged in the fair's guest book are overwhelmingly positive. "Wow, the world is shrinking," wrote a visitor from the Netherlands. Since their initial hesitancy, the major sponsors-primarily telecommunications and software companies--have become firm believers. Beyond the diversity of content and international scope, the fair is a technological marvel. The fastest international link ever installed, this pipeline could be the first step toward laying a permanent network that will eventually hardwire every nation in the world into the Internet. The organizers hope that the infrastructure--and awareness-nurtured by this exposition will launch a boom in Net use.

单选题{{B}}Text 2{{/B}} Any normal species would be delighted at the prospect of cloning. No more nasty surprises like sickle cell or Down syndrome--just batch after hatch of high-grade and, genetically speaking, immortal offspring! But representatives of the human species are responding as if someone had proposed adding Satanism to the grade-school Curriculum. Suddenly, perfectly secular folks are throwing around words like sanctity and retrieving medieval-era arguments against the pride of science. No one has proposed burning him at the stake, but the poor fellow who induced a human embryo to double itself has virtually recanted--proclaiming his reverence for human life in a voice, this magazine reported," choking with emotion." There is an element of hypocrisy to much of the anti-cloning furor, or if not hypocrisy, superstition. The fact is we axe already well down the path leading to genetic manipulation of the creepiest sort. Life-forms can be patented, which means they can be bought and sold and potentially traded on the commodities markets. Human embryos are life-forms, and there is nothing to stop anyone from marketing them now, on the same shelf with the Cabbage Patch dolls. In fact, any culture that encourages in vitro fertilization has no right to complain about a market in embryos. The assumption behind the in vitro industry is that some people's genetic material is worth more than others' and deserves to be reproduced at any expense. Millions of low-income babies die every year from preventable ills like dysentery, while heroic efforts go into maintaining yuppie zygotes in test tubes at the unicellular stage. This is the dread "nightmare" of eugenics in familiar, marketplace form--which involves breeding the best-paid instead of the best. Cloning technology is an almost inevitable byproduct of in vitro fertilization. Once you decide to go to the trouble of in vitro, with its potentially hazardous megadoses of hormones for the female partner and various indignities for the male, you might as well make a few backup copies of any viable embryo that's produced. And once you've got the backup organ copies, why not keep a few in the freezer, in case Junior ever needs a new kidney or cornea? The critics of cloning say we should know what we're getting into, with all its Orwellian implications. But if we decide to outlaw cloning, we should understand the implications of that. We would be saying in effect that we prefer to leave genetic destiny to the crap shooting Of nature, despite sickle-cell anemia and Tay-Sachs and all the rest, because ultimately we don't trust the market to regulate life itself. And this may be the hardest thing of all to acknowledge, that it isn't so much 21st century technology we fear, as what will happen to that technology in the hands of old-fashioned 20th century capitalism.

If all the Barbies and her family members-Skipper, Francie and the rest-sold since 1959 were placed head to toe, they would circle the Earth more than seven times. And sales are sure to boom in 2009, when the fashion doll celebrates her 50th birthday on March 9th. Barbie will star at an array of global events honouring her milestone, possibly including a glitzy affair at New York's Fashion Week in February (most of the world's top fashion designers, from Givenchy to Alexander McQueen, have designed haute couture for her). On her birthday, Mattel, the company that makes her, will launch a souvenir doll honouring the original Barbie in her black-and-white striped swimsuit and perfect ponytail. It will be available for purchase only that one day. Another Golden Anniversary doll targets collectors. Barbie fans have planned hundreds of events, including the National Barbie Doll Collectors Convention in Washington, DC, which is already sold out. When Ruth Handler created Barbie in 1959, a post-war culture and economy thrived but girls still played with baby dolls. These toys limited the imagination; so Handler introduced Barbie the Teen-Age Fashion Model, named after her daughter, Barbara. Jackie Kennedy soon sashayed onto the world stage and Barbie already had a wardrobe fit for a first lady. Barbie bestowed on girls the opportunity to dream beyond suburbia, even if Ken at times tagged along. Barbie entranced Europe in 1961 and now sells in 150 countries. Every second three Barbies are sold around the world. Her careers are myriad-model, astronaut, Olympic swimmer, palaeontologist and rock star, along with 100 others, including president. Like any political candidate, controversy hit Barbie in 1992 when Teen Talk Barbie said "Math class is tough" and girls' education became a national issue. She has been banned (in Saudi Arabia), tortured (by pre-teen girls, according to researchers at the University of Bath's School of Management) and fattened (in 1997). Feminists continue to bash Barbie, claiming that her beauty and curves treat women as objects. But others see her as a pioneer trendsetter, crashing the glass ceiling long before Hillary Clinton cracked it. High-tech entertainment now attracts girls and Barbie also faces fierce competition from various copycats including the edgier, but less glare, Bratz dolls. The Bratz suffered a setback in 2008．Mattel sued MGA Entertainment, Bratz's producer, for copyright infringement. A judge awarded Mattel $100 million in damages. Mattel has smartly ensured that Barbie products reflect current trends. Through two Barbie websites, girls can design clothes, network and play games. The pink Barbie brand is licensed for products from DVDs and MP3 players to bicycles and even 24-carat gold and crystal jewellery. Barbie collectors fuel an entire global industry on eBay and at conventions. To entice collectors, Mattel regularly releases pricey limited-edition dolls based on characters in films and popular culture. Industry analysts believe Barbie will remain a bestselling and lasting icon regardless of competition. "Barbie's been out in the world and had fun, and she's ready for her second career," says Rachel Weingarten, a pop culture expert. "I don't see her adopting five children from five different countries, but I could see Barbie with a conscience, activist Barbie. " At 50 Barbie will also be a marvel of plastic surgery and eternal youth. And she still knows how to party.

单选题Africa's elephants are divided between the savannahs of eastern and southern Africa and the forests of central Africa. Some biologists reckon the forest ones-smaller, with shorter, straighter tusks-may even constitute a distinct species. But not for long, at the latest rate of poaching. The high price of ivory is increasing the incentive to kill elephants everywhere in Africa, and especially in places where there is virtually no law. The latest reports suggest that the forest elephant population is collapsing on the back of rising Chinese demand for ivory. Some conservationists argue that a recent decision by the Convention on International Trade in Endangered Species (CITES) to auction 108 tonnes of stockpiled ivory from southern Africa may be prompting more poaching in central and eastern Africa, as criminals seek to mix illicit ivory in with the legitimate kind. But some economists maintain that the legitimate sale of ivory lowers prices, thus decreasing the incentive to poach. A study of a previous sale of ivory suggested it did not lead to more intensive poaching. Either way, the Congo basin is " hemorrhaging elephants ", says TRAFFIC, which monitors trade in wildlife. The head of the 790,000-hectare (1,952,000-acre) Virunga National Park in eastern Congo, Emmanuel de Merode, reports that 24 elephants have been poached in his park so far this year. The situation is dire: 2,900 elephants roamed Virunga when Congo became independent in 1964,400 in 2006, and fewer than 200 today. Most have been poached by militias, particularly Hutu rebels from Rwanda who hack off the ivory and sell it to middlemen in Kinshasa, Congo's capital, who then smuggle it to China. Once ivory has left its country of origin, and if it is not seized by customs officials, it can be hard to identify its source and those responsible for acquiring it. But forensic help may be at hand. Scientists from the University of Washington are using genetic markers in elephant dung to identify exactly where ivory has been poached. This should help governments in countries such as Tanzania and Zambia, which are capable of catching poachers, but not in anarchic eastern Congo, where 120-odd rangers have been killed in Virunga in recent years trying to protect elephants and gorillas. With an influx of businessmen and other officials from China engaged in infrastructure projects such as road building and logging, the slaughter is expected to accelerate. Forest elephants may survive in large numbers only in remote protected pockets of the Congo basin, such as the Odzala-Koukoua National Park in Congo-Brazzaville and Minkebe National Park in northeast Gabon.
