单选题{{B}}Passage 4{{/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 about-2 245 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 hags, 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The status given to waiters in a restaurant varies in different parts of the world. For example, in some places working as a waiter is seen as having low status, like being a servant. In other places, it is viewed as a useful and important role and people who do the job well are respected. Eddie Lam has been a waiter for four years and clearly thinks he has a good job. He is proud that he knows how to give good service to guests in the restaurant where he works. "I enjoy learning about people—their likes, dislikes and their moods. I make an effort to show them that I care," he explains. "It takes experience to understand how to make someone happy." Eddie knows that when he talks about his customers, it may sound like he is talking about his friends or his family. "There are actually many similarities in the relationship, although the relationship between waiter and customer may only last a short time," he laughs. Eddie believes that waiters have to be very observant. They need to notice quickly when a customer is bothered, for example, if they don't have a knife, or if they want a glass of water. It is also important for them to recognise when someone is in a hurry or when a couple want to be left undisturbed for a while. And all this should happen without the customers realizing; they just get what they want. He points out that when service is good, the customers are often not aware of it. However, if customers receive bad service in a restaurant, they usually react very quickly. "I suppose the tips left by customers are part of my financial reward," says Eddie, "but I also get a lot of satisfaction just from seeing customers relaxing and enjoying their meals."

单选题Early this week a bit of cheery news was reported by the Manhattan Institute, a conservative think tank: black segregation has hit its lowest point in more than a century — declining in all 85 of the nation"s largest metropolitan areas. Nevertheless, the report is largely celebratory in tone, and it has been received in that fashion by much of the news media. Before we break out the champagne, however, it may be wise to pause and reflect for a moment on who was excluded from the analysis. Our nation"s prison population has more than quintupled (soaring from 300, 000 in the mid-1970s to more than 2 million today), due to a "get tough" movement and a war on drugs that has been waged almost exclusively in poor communities of color. Studies have consistently shown that people of color are no more likely to use or sell illegal drugs than whites, but a fierce drug war has been waged nonetheless, and harsh mandatory minimum sentences passed, leading to a prison-building boom unprecedented in world history. Despite this sea change, prisoners continue to be treated as nonentities in much sociological and economic analysis. In the Manhattan Institute study, prisoners are not even mentioned, despite the fact that millions of poor people — overwhelmingly people of color — are removed from their communities and held in prisons, often hundreds of miles from home. Most new prison construction has occurred in predominately white, rural communities, and thus a new form of segregation has emerged in recent years. Bars and walls keep hundreds of thousands away from mainstream society — a form of apartheid unlike the world has even seen. If all of them suddenly returned, they would not be evenly throughout the nation"s population. Instead they would return to a relatively small number of communities defined by race and class, greatly intensifying the levels of segregation we see today. Those who imagine that the failure to account for prisoners can"t possibly affect the analysis would be wise to consider the distortion of unemployment figures in recent years. According to Harvard professor Bruce Western, standard unemployment figures underestimate the true jobless rate by as much as 24 percentage points for less educated black men. In fact, during the 1990s — the economic-boom years — no college black men were the only group that experienced a sharp increase in unemployment, a development directly traceable to the sudden explosion of the prison population. At the same time that unemployment rates were sinking to record low levels for the general population, the true jobless rate among no college black men soared to a staggering 42%. Prisoners do matter when analyzing the severity of racial inequality in the U. S. Yet because they are out of sight and out of mind, it is easy to imagine that we are making far more racial progress than we actually are. For now, let"s keep the cork in the bottle and pray that we will eventually awaken from our color-blind slumber to the persistent realities of race in America.
