单选题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—2,235 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 stoties 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A hundred years ago it was assumed and scientifically "proved" by economists that the laws of society make it necessary to have a vast army of poor and jobless people in order to keep the economy going. Today, hardly anybody would dare to voice the principle. It is generally accepted that nobody should be excluded from the wealth of the nation, either by the law of nature or by those of society. The opinions are outdated, which were current a hundred years ago, that the poor owed their conditions to their ignorance, lack of responsibility. In all western industrialized countries, a system of insurance has been introduced which guarantees everyone a minimum of subsistence in case of unemployment, sickness and old age. I would go one step further and argue that, even if these conditions are not present, in other words, one can claim this subsistence minimum without having to have any "reason". I would suggest, however, that it should be limited to a definite period of time, let's say two years, so as to avoid the encouragement of an abnormal attitude which refuses any kind of social obligation. This may sound like a fantastic proposal, but so, I think, our insurance system would have sounded to people a hundred years ago. The main objection to such a scheme would be that if each person were entitled to receive minimum support, people would not work. This assumption rests on the fallacy of the inherent laziness. In human nature, actually, aside from abnormally lazy people, there would be very few who would not want to earn more than the minimum, and who would prefer to do nothing rather than work. However, the suspicions against a system of guaranteed subsistence minimum are not groundless from the standpoint of those who want to use ownership capital for the purpose of forcing others to accept the work conditions they offer. If nobody were forced to accept work in order not to starve, work would be sufficiently interesting and attractive in order to induce one to accept it. Freedom of contract is possible only if both parties are free to accept and reject it~ in the present capitalist system this is not the case. But such a system would not only be the beginning of real freedom of contract between employers and employees; its principal advantage would be the improvement of freedom in interpersonal relationships in every sphere of daily life.

单选题 One of the most widely discussed subjects these days is. energy crisis. Automobile drivers cannot get gasoline; homeowners may not get enough heating oil; factories are{{U}} (56) {{/U}}by a fuel shortage. The crisis has{{U}} (57) {{/U}}questions about the large oil companies and windfall{{U}} (58) {{/U}}. Critics of the oil industry charge that the major companies are getting richer because of the oil shortage. Shortage, of course, drives prices up. As oil prices rise, the critics say, the oil companies will make more money (windfall profits) without doing a thing to{{U}} (59) {{/U}}the extra cash. "Windfall" profits are sudden unearned profits--profits made{{U}} (60) {{/U}}luck, or some special turn of events. The word itself tells what "windfall" means--something blown down by the wind, such as trees, or fruit{{U}} (61) {{/U}}from trees. But the word has taken on a special meaning. This meaning (getting something unearned) was first used in medieval England. This is{{U}} (62) {{/U}}it started: at that time much of the land was in the hands of{{U}} (63) {{/U}}barons. The rest of the people, commoners, lived and worked on their vast estates. They planted the seed, cared for the farm animals and harvested the crops. Not all the land, however, was used for farming. Every baron kept a large private forest for{{U}} (64) {{/U}}deer and wild bear. When hungry, the people sometimes would kill the animals in the lord's forest for food. And there were times{{U}} (65) {{/U}}they might cut down trees for fuel. So, strong laws were passed to protect the forests, and the animals. Violations were severely{{U}} (66) {{/U}}. But there was one way people could get wood from the forest. If they found trees blown down by the wind ("windfall") they were free to take them for use as fuel in their homes. And that is the meaning that has come down to us--something good gotten by luck or{{U}} (67) {{/U}}. The common people of old England, often hungry and cold, must often have prayed for a good strong wind. Critics today{{U}} (68) {{/U}}that the oil industry has also been praying for something just like it --some political or military{{U}} (69) {{/U}}that might produce a windfall--a rise in oil prices and profits. The oil companies deny that this is so. In Congress, critics of the oil companies have proposed a{{U}} (70) {{/U}}on such profits. The debate on rising oil price will go on for some time, and most likely we will hear more and more about windfall profits.

单选题{{B}}Passage Two{{/B}} If those "{{U}}mad moments{{/U}}"— when you can't recall what your friend has told you or where you left your keys—are becoming more frequent, mental exercises and a healthy brain diet may help. Just as bodies require more maintenance with the passing years, so do brains, which scientists now know show signs of aging as early as the 20s and 30s. "Brain aging starts at a very young age, younger than any of us have imagined and these processes continue gradually over the years," said Dr. Gary Small, the director of the Center on Aging at the University of California, Los Angeles. "I'm convinced that it is never too early to get started on a mental or brain-fitness program," he added. In his book, "The Memory Bible," the 51-year-old neuroscientist lists what he refers to as the 10 commandments for keeping the brain young. They include training memory, building skills, minimizing stress, mental exercises, brain food and a healthy lifestyle. It's a game plan for keeping brain cells sparking and neural networks in tip-top shape. "Misplacing your keys a couple of times doesn't mean you should start labeling your cabinets. Memory loss is not an inevitable consequence of aging. Our brains can fight back," he said. Small provides the weapons for a full-scale attack. According to him, simple memory tests give an indication of what you are up against and tools such as look, snap and connect are designed to make sure that important things such as names and dates are never forgotten. "So if you want to learn names and faces, for example, you meet Mrs. Beatty and you notice a distinguishing facial feature, maybe a prominent eyebrow," said Small. "You associate the first thing that comes to mind. I think of the actor Warren Beatty so I create a mental snapshot of Warren Beatty kissing her brow. " Small admits it may sound a bit strange but he says it works. " Mental exercises could be anything from doing crossword puzzles and writing with your left hand if you are right handed or learning a language. It could be anything that is fun that people enjoy doing", he added. He also recommends physical exercise, a low-fat diet and eating foods rich in omega-3 fatty acids, such as fish, walnuts and Brazil nuts, and fruits and vegetables high in antioxidants (抗氧化剂) including blueberries and onions in addition to reducing stress.

单选题The history of transportation is very long and full of changes and inventions. It starts 1 walking, which is not any invention; it just takes energy. People used to walk to get to other places. If you wanted to get somewhere quickly, the 2 way to do that was to run. Actually, the first invention for transportation 3 was the shoe. Centuries ago there were no shoes, and people walked barefoot. Then people invented 4 to transport themselves and materials from one place to another. In some cultures, people invented sledges (雪橇), 5 are a kind of board that you drag along the ground. You can tie things on the sledge to help carry them, but it"s a challenging invention 6 if you hit a rock with the sledge as you pull it, the contents can 7 . In other cultures, people invented the wheel, which they used to make it easier to move things—and people. That was the beginning of many innovations in transportation. 8 people had wheels they could invent other ways to travel. They could put the wheel on a board and make it a wagon, and then they could 9 that wagon to an ox or a horse and ride as well as carry materials. That wheel led to 10 we have today: trucks, automobiles, and even boats and planes. For example, there were steamboats that used giant wheels that turned with blades, pushing the water and pushing the boat forward.
