单选题{{B}}Passage Four{{/B}} When I was still an architecture student, a teacher told me, "We learn more from buildings that fall down than from buildings that stand up.' What he meant was that construction is as much the result of experience as of theory. Although structural design follows established formulas, the actual performance of a building is complicated by the passage of time, the behavior of users, the natural elements—and unnatural events. All are difficult to simulate. Buildings, unlike cars, can't be crash-tested. The first important lesson of the World Trade Center collapse is that tall buildings can withstand the impact of a large jetliner. The twin towers were supported by 59 perimeter columns on each side. Although about 30 of these columns, extending from four to six floors, were destroyed in each building by the impact, initially both towers remained standing. Even so. the death toll (代价)was appalling—2245 people lost their lives. I was once asked, how tall buildings should be designed given what we'd learned from the World Trade Center collapse. My answer was, "Lower. " The question of when a tall building becomes unsafe is easy to answer. Common aerial fire-fighting ladders in use today are 100 feet high and can reach to about the 10th floor, so fires in buildings up to 10 stories high can be fought from the exterior (外部). Fighting fires and evacuating occupants above that height depend on fire stairs. The taller the building, the longer it will take for firefighters to climb to the scene of the fire. So the simple answer to the safety question is "Lower than 10 stories." Then why don't cities impose lower height limits? A 60-story office building does not have six times as much rentable space as a 10-story building. However, all things being equal, such a building will produce four times more revenue and four times more in property taxes. So cutting building heights would mean cutting city budgets. The most important lesson of the World Trade Center collapse is not that we should stop building tall buildings but that we have misjudged their cost. We did the same thing when we underestimated the cost of hurtling along a highway in a steel box at 70 miles per hour. It took many years before seat belts, air bags, radial tires, and antilock brakes became commonplace. At first, cars simply were too slow to warrant concern. Later, manufacturers resisted these expensive devices, arguing that consumers would not pay for safety. Now we do—willingly.

单选题From a very early age, some children exhibit better self-control than others. Now, a new study has tracked how low self-control can predict poor health, money troubles and 31 a criminal record in their adult years. The study began with 1,000 children in New Zealand. Researchers followed them for 32 . They observed the level of self-control the youngsters 33 . Parents, teachers, even the kids themselves, scored the youngsters on measures like "acting before thinking" and " 34 in reaching goals." The children of the study are now adults in their thirties. Terrie Moffitt of Duke University found that kids with self-control issues 35 to grow up to become adults with a far more troubling set of issues to deal with. "The children who had the lowest self-control 36 they were age three to ten, early years, later on had the most health problems in their thirties," Moffitt said, "and they had the worst 37 situation. They were more likely to have a criminal record and to be raising a child as a single parent 38 a very low income." Moffitt said it"s still unclear why some children have better self-control than others, 39 other researchers have found that it"s mostly a learned behavior, with relatively little 40 influence. But good self-control can run in families because children with good self—control are more likely to grow up to be healthy and prosperous parents.

单选题{{B}}Passage Four{{/B}} Just a few years ago, a graduate from Brown University medical school had just an {{U}}inkling{{/U}} about how to care for the elderly. Now, Brown and other U. S. medical schools are plugging geriatric (老年) courses into their curricula. The U.S. Census Bureau projects the number of elderly Americans will nearly double to 71 million by 2030. The first members of the Baby Boomer generation, so named for the explosion in births in the years after World War Two, turn 65 in three years. In addition, people are living longer than ever. "The first ripples of the silver tsunami are lapping at the shores of our country, but there is not a coordinated or strategic response taking place in America," said Richard Besdine, who is direetor of the geriatrics division at Brown University medical school in Providence. Geriatries has never been a field of choice for young doctors. Elderly care doctors are paid less than most other physicians and surgeons and the aged can be hard to treat. They have complicated medical histories and their ailments, even such routine illnesses as pneumonia (肺炎), can be more difficult to diagnose because they may be masked by other conditions. Also, drugs can affect them differently than middle-aged adults." It's a hard job; it's not paid very well; it's complicated; and there's very little status within the hierarchy of medical specialties to being a geriatric physician," said Gavin Hougham, senior program officer and manager of medicine programs at the John A. Hartford Foundation. Out of 800 000 doctors in the United States, roughly 7 000 are geriatricians, Hougham said. The country needs another 13 000 to adequately care for today's older population, according to the American Geriatrics Society. The shortfall could reach 36 000 by 2030. To help counter that, private groups are bankrolling medical schools' emphasis on aging. The Hartford Foundation has given more than $40 million to 27 schools to train faculty in elderly care, and the Donald W. Reynolds Foundation has given more than $100 million to 30 schools to include more geriatrics content. "If they don't learn it, they still have to deal with it," Hougham said. "It's not that not learning geriatrics will cause these older people to go away. They're coming whether we're ready or not. "
