Even more troubling than the increasing number of inhabitants are the projections of where they will be concentrated. The study by Rafael M. Solos, executive director of the U. N. Fund for Population Activities, notes that by the year 2000: Nearly 80 percent of all people will live in less developed countries, many hard pressed to support their present populations. That compares with 70 percent today. In many of these Third World lands metropolises (大城市) will become centers of concentrated urban poverty because of a flood of migration from rural areas. The bulging(膨胀的) centers mainly in Asia and Latin America, will increasingly become fertile fields for social unrest. More young residents of the urban clusters(一群) will be better educated, unemployed and demanding of a better lifestyle. To slow the rush to urban centers, countries will have to vastly expand opportunities in the country side, the study suggests. Solos says: "The solution to the urban problem lies as much in the rural areas as in the cities themselves." Worldwide, the numer of large cities ,will multiply. Now 26 cities have 5 million or more residents each and a combined population of 252 million. By the end of the decade, the number will escalate to 60. with an estimated total of almost 650 million people. In the last paragraph, the word "escalate" means ______. A．decrease B．increase C．go down D．decline

The Market for Adventures offers customers safaris, theme parks, sports, and action/ adventure TV shows and movies. Nike's ties to the "Adventure" market made it willing to pay a reported ＄400 million simply for the right to sponsor Brazil's outstanding national soccer team, thereby boosting the brand's image as the footwear of champions. Such an investment makes sense in a market where consumers find many products with comparable features and quality and must find some reason to choose one over the others. The Market for Love, Friendship, and Togetherness has such offerings as perfume, gifts, home photography, restaurants, and entertainment. Tapping the "Togetherness" market, Guinness Brewery has teamed with an Irish firm to establish a chain for "authentic" Irish pubs in cities around the world--where Irish charm and British beer sell briskly in each other's company. The Market for Care recently offered a product that captured children's desire to nurture and care for pets. The Tamagotchi is a demanding little electronic puppy that beeps for attention from its owner. Real pets are becoming hotel amenities in some places. The Who-Am-I Market offers products that proclaim their owner's identity, like fashion, automobiles, and accessories. Louis Vuitton suitcases, for instance, tell a story that their owners want to tell the world: "I am an exciting person, gliding with perfect ease through pos}t hotels all over the world, and I do it in style. ' Other consumers may want their purchases to proclaim their environmental awareness, so they may buy "bird friendly" coffee, grown only in shaded areas so endangered birds may be preserved. Eco-Sustainable Shady coffee and Caribou Coffee's Rainforest Blend are among several such offerings. The Peace of Mind Market features nostalgia, history, and antiques. In rapidly changing times, many people seek the serenity of the familiar, be it the bistros of Paris or small-town life in the US. For instance, First National Bank in Brookings, South Dakota, proclaims, "We strive to maintain the small-town banking atmosphere while growing and changing with the technological age. " The Conviction Market, last of the six markets, includes "green" products, humane testing, and worker welfare. While many companies may be reluctant to become overly political, they can highlight their involvement in the community and market to their customers' need to make purchase that are in line with their convictions. Among companies taking this approach are British Petroleum, which uses its Web site to report on the company's Community Development Programme, and Mobil, which accentuates its concern for local populations of countries in which it does business. Jenson believes that companies will increasingly let consumers in on the story-telling process. Companies will come to value storytellers not only in their creative advertising departments, but in executive positions, where refashioning a company's history and traditions into an appealing myth will be crucial for winning the enthusiasm of employees, the affection of customers, and the respect of the general public. As the stories get better, sales should soar. What may be Roll Jensen's main purpose of classifying these six distinct markets？ A．To classify different companies into corresponding market. B．To invite businesses to consider how to best profit from them. C．To set some models for companies in the market. D．To predict trends in the market.

The report acknowledges great progress has been made in the eradication of certain childhood diseases such as polio and measles. However, it emphasizes that for millions of the world' s children, armed conflicts, disease and forced labor continue to take a heavy toll. Susan Surandon, the American film actress who is recently appointed UNICEF special representative, told reporters that 3 main factors are endangering the lives and futures of the world' s children. "Poverty is killing our children; HIV is killing our children, disproportionately in sub-Saharan Africa; armed conflict is killing our children. And when I say killing, I mean their bodies and their souls their futures, our futures." Ms. Surandon cited statistics which show that in the last decade 2 million children died in wars, 6 million were disabled as the result of armed conflicts, and 14 million have been orphaned by the disease AIDS. A special focus in this year' s UNICEF report is on the rights of adolescents. No longer children in the traditional sense, the report says adolescents still need positive support and guidance and the opportunity to finish school. Breck Ardery, VOA News, at the United Nations.

“Breast-feeding not only has short-term benefits, but also breast-feeding has long-term benefits, ” says Bernardo Lessa Horta of the Federal University of Pelotas in Brazil, who led the study being published in The Lancet Global Health. Doctors have long known that breast-feeding can be good for a baby’s health. This is especially true in poor countries, where water can be contaminated. For instance, a baby given formula in developing countries is 14 times more likely to die in the first six months than one who’s breast-fed. In the U.S., some research has suggested that breast-feeding may raise a baby’s IQ(智商)by a few points. But a recent study with siblings(兄弟姐妹)found little advantage to breast-feeding. Horta says these previous studies didn’t follow children into adulthood to see if breast-feeding had long-term effects. So Horta analyzed data collected from 3,493 volunteers he and his colleagues have been following since birth. They are now in their 30s. First, the researchers gave the subjects IQ tests. Those who were breast-fed for 12 months or more had IQ test scores that were 3.76 points higher than those who were breast-fed for less than one month, the team found. When Horta and his colleagues looked at how much education the subjects had gotten and how much money they were making, they also found a clear difference: Those who were breast-fed the longest stayed in school for about an extra year and had monthly salaries that were about a third higher. 1.
