单选题E Not everyone in the world requires the same amount of living space. The amount of space a person needs around him is a cultural (文化的) difference, not an economic (经济的) one. Knowing your own psychological (心理的) space needs is important because they strongly affect your choices, including, for example, the number of bedrooms in the home. If you were brought up in a two-child family and both you and your sister or brother had your own bedrooms, the chances are, if you have two children or more, that you also will offer separate (分开的) bedrooms for them. In America, for example, they train people to want to have their own rooms by giving them their own rooms when they are babies. This is very rare in the world. In many other countries, the baby sleeps in the same bed with his parents or in bed near them. The space in the home also shows a lot about psychological space needs. Some families gather closer to each other and the size of their house have nothing to do with it. Others have separate little corners where family members go to be alone. Although it is true that psychological space needs are not decided by economic reasons, they sometimes have to be changed a little because of economic pressures. It is almost impossible, however, to completely change your psychological space needs.

单选题Intensive research is yielding (产生) important insight into El Ni ? o, a periodic warming of tropical waters in the Pacific that can trigger devastating drought and flooding. Scientists are finding that the phenomenon exists in reverse; some call it La Ni ? a. Typically El Ni ? o, like the calamitous 1982-1983 event that brought misery to places as far apart as Ecuador, Australia, and southern Africa (National Geographic, February 1984), announces itself with strong westerly winds along the Equator (赤道), accompanied by a warm current that usually arrives off western South America around Christmas, which led to its name, Spanish for "the Child". Ocean fisheries (渔业) suddenly collapse, and coastal deserts reel under torrential rains that sweep away villages. Scientists now believe that between El Ni ? o there often are La Ni ? a: one-or-two-year periods when the surface water of the equatorial Pacific becomes cooler. Experts detected the onset of La Ni ? a in the spring of 1988, leading some to link it to last summer"s drought in the United States, flooding in Bangladesh, and the abnormal cold winter in Alaska and western Canada. The early detection of El Ni ? o and La Ni ? a is an invaluable tool for long-range weather forecasting.

"We slept in our car for about a week," she said, "but then it was sold." As she moved from one friend's house to another, Carr began working toward a high-school- equivalence diploma, listening to self-help tapes and making cheesecakes. After developing some new methods which she thought were pretty good, she offered her cakes to a restaurant. They sold out in a matter of hours. The following year, she met a man at a church service and before long, they married. Carr began selling the cheesecakes out of their home. Later she opened a cheesecake company. As business became better and better, Carr didn't forget where she came from. All the women she hires are mothers or high-school dropouts (退学者)--workers most other employers wouldn't like to hire. Her dozen workers make 100 to 150 cakes a week and Cart owes her success to her employees. She says, "We're going to have a learning center and a day-care center in the company. Part of the workday will be spent studying for high-school-equivalence diplomas." Recently, a 33-year-old woman with three children to raise was referred to Cart. She hired her at once. "It has been a real blessing," the woman said.

单选题The success story started in northern Italy towards the end of the Second World War. Leone Benetton had a bicycle rental (租赁) business in the town of Treviso. He wanted his oldest son Luciano to study and become a doctor. After Leone died, the family was poor and Luciano decided to leave school and get a job. He found work in a clothing store but soon had his own ideas and started a family clothing company producing colorful woolen sweaters for people only used to wearing dull colors. Shops selling only Benetton sweaters opened in many Italian cities and by 1974 there were stores in France, Germany and Belgium. It was clear that at this stage the success of the Benetton business lay in the strength of the family. In 1975 Luciano married the 20-year-old Marina Salomon who worked in one of his shops. After careful research, Benetton opened his first shop in the USA, in Manhattan, New York, where it attracted some very special customers including Princess Diana and Jackie Onassis. In 1982 Luciano was introduced to Oliviero Toscani, the photographer who was to change the image (形象) of Benetton forever. Although Benetton was growing very quickly, they needed an international image and for this reason in the early 1980s they decided to provide money for Formula 1 motor racing. This was followed by the advertising campaigns (广告攻势) for which the company became famous. Luciano Benetton succeeded in turning the company he started in the 1950s into one of the world's most successful businesses but he paid a high personal price. He spent so much of his life working and traveling that he lost touch with his family and friends.

单选题Understanding how nature reacts to climate (气候) change will require checking key life cycle events--flowering, the appearance of leaves, the first frog calls of the spring--all around the world. But ecologists (生态学家) can't be everywhere, so they're turning to non-scientists, sometimes called citizen scientists, for help. A group of scientists and educators set up an organization last year called the National Phenology Network. "Phenology" is what scientists call the study of the timing of events in nature. One of the group's first efforts is to ask scientists and non-scientists to collect information about plant flowering and leafing every year. The program, called Project BudBurst, collects life cycle information on a variety of common plants from across the United States. People taking part in the project record their information on the Project BudBurst website. "People don't have to be scientists--they just have to look around and see what's in their neighbourhood," says Jennifer Schwartz, a scientist with the project. "As we collect this information, we'll be able to know about the changes of plants and animals as the climate changes. " Not only that, the information also helps scientists learn about how these changes will have an effect on people, Scientists examining lilac (丁香花) flowering in western United States reported that in years when lilacs flowered early--before May 20th-wildfires later in the summer and fall were likely to be larger and more serious. Lilac flowering, then, could serve as an alarm bell. "The best way for us to increase our knowledge of how plants and animals are reacting to climate change is to increase the count of information we have," Schwartz says. "That's why we need citizen scientists to get as much information from as many places on as many plants and anireals over as long a time period as we can. /
