第7题

Rupert Murdoch once described them as the "rivers of gold"—the lucrative classified-advertising revenues that flowed into big newspaper groups. But the golden rivers are being diverted online as the Internet breaks the grip that local and regional newspapers once held over their advertising markets.

Typically, a local newspaper would expect to get some 80% of its revenue from advertising, of which around two-thirds would come from classifieds. But last year in the San Francisco Bay area, job ads worth some $60m were lost from newspapers to the web, reckons Classified Intelligence, a consultancy. Emap, a British publisher, recently gave warning of a 30% decline in recruitment ads in one of its titles, Nursing Times, following the launch of a free website for jobs in Britain's National Health Service.

The Internet has become the fastest-growing advertising medium. Online ad revenues reached $5.8 billion in the first six months of this year in America, up 26% on the same period last year, according to a joint study by the Interactive Advertising Bureau and Pricewaterhouse-Coopers. In Britain, online ad revenues surged by 62% in the same period to almost £500m ($870m).

Search advertising—the small text-ads that appear alongside Google and Yahoo! searches—ac count for 40% of the online ad market. Another 20% goes to display ads and 18% to classified advertising. But search advertising can also work like a small ad and will increasingly challenge print classifieds as websites develop localized and more elaborate services for online users.

Perhaps the most significant development came on November 16th, when Google started up a prototype service called Google Base. It offers a searchable database of free listings, including small ads which can be narrowed down to postal regions. Among its first Offerings were used cars. In no time, Google could challenge eBay, whose own auction listings now work much like a giant classified website—especially with its "buy-it-now" options. But eBay charges sellers. Even so, it sold more than 450m items in the three months to September 30th, for almost $11 billion.

In response, most print publishers are expanding online. Mr. Murdoch is buying websites including Propertyfinder and MySpace, a social-networking site. Newspaper groups have teamed up to jointly operate websites to compete with Monster for recruitment ads. But the online operators are expanding too. eBay, for instance, is building a global network of classified sites under the Kijiji brand. It also has a stake in the popular Craigs-list which, having soaked up so many listings around its San Francisco home, is now frightening other newspapers as it expands its mostly-free ads service to other cities around the world.

By saying "the golden rivers are being diverted", the author means

A.newspapers earn a lot from ads.

B.the money flow like rivers into websites.

C.newspapers began to share the ad revenues with websites.

D.websites took away many ad revenues from newspapers.

第8题

―Five ? Four ? Three ? Two ? One ? See ya! ‖ and Chance McGuire, twenty-five, is airborne off a 600 –foot concrete dam in Northern California. In one second he falls 15 feet, in two seconds 60 feet, and after three seconds and 130 feet, he is flying at 66 miles an hour. McGuire is a practitioner of what he calls the king of all extreme sports. BASE—an acronym for building, antenna, span (bridge) and earth (cliffs)—jumping has one of the sporting world’s highest fatality rates: in its 18-year history, forty –six participants have been killed. Yet the sport has never been more popular, with more than a thousand jumpers in the United States, and more seeking to get into it every day. It is an activity without margin for error. If your chute malfunctions, don’t bother researching for a reserve—there isn’t time. There are no second chances. Still, the sport may be a perfect fit with the times. Americans may have more in common with McGuire than they know or care to admit. America has embarked on a national orgy of thrill seeking and risk taking. The rise of adventure and extreme sports such as BASE jumping, snowboarding, ice climbing, skateboarding, and paragliding is merely the most vivid manifestation of this new national behavior. The rising popularity of extreme sports speaks of an eagerness on the part of millions of Americans to participate in activities closer to the edge, where danger, skill, and fear combine to give weekend warriors and professional athletes alike a sense of pushing out personal boundaries. According to American Sports Data Inc., a consulting firm, participation in so-called extreme sports is way up. Snowboarding has grown 113 percent in five years and now boasts nearly 5.5 million participants. Mountain hiking, skateboarding, scuba diving—their growth curves reveal a nation that loves to play with danger. Contrast that with activities such as baseball, touch football, and aerobics, all of which were in steady decline throughout the 1990s. The pursuits that are becoming more popular have one thing in common: the perception that they are somehow more challenging than a game of touch football. ―Every human being with two legs and two arms is going to wonder how fast, how strong, how enduring he or she is,‖ says Eric Perlman, a mountaineer and film maker specializing in extreme sports. ―We are designed to experience or die.‖ Questions 1—3 Complete the following sentences with information given in the passage in a maximum of 4 words for each blank. 1、 _______ rates doesn’t stop people from getting into BASE jumping every day. 2、 The rise of extreme sports manifests the national behavior of _______ and ________. 3、The combination of fear, skill and danger gives both amateurs and professionals a sense of ______. Questions 4—5 Choose the best answer according to the passage. 4、 Which of the following activities reveals a nation that loves to play activities closer to the edge? A. Touch football. B. Baseball. C. Scuba diving. D. Aerobics.5、 What does Eric mean by saying ―We are designed to experience or die‖? A. Life with great challenges is a meaningful one. B. Life without great experiences is very common.C. People may die while doing extreme sports. D. Extreme sports are essential parts of human life.
