单选题{{B}}第三篇{{/B}} {{B}} Changes in the American Family{{/B}} How much change has really occurred in the American family and what are the implications of these changes? First, the household size has changed greatly since 1790. From 1790 to 1978 the mean family size was cut in half from 5.79 persons to 2.81 persons. In 1790 almost 63 percent of all persons lived in the households of five or more people. By 1978 the size accounted for a little over 14 percent of all households. By the end of the 19th century a majority of Americans were living in urban areas, and the family was very much influenced By the rapid development of industrialization. With the arrival of immigrants, the urban population was increasingly heterogeneous(由不同成分组成的). This challenges the exclusiveness of any single family pattern. In the 20th century, the ideal American family consisted of a husband and wife living with dependent children. They lived in a household of their own provided for by the husband's earnings. The wife was responsible for emotional maintenance of the marriage and for raising the children and running the household. The major change in the family in this century has been due to married women entering the work force. This, at least for periods of time, has taken the woman out of her full-time involvement in the home. Of all husband and wife families about 40% have both in the work force at any given time. In the past the identity of the individual was submerged in the family. In general, reputation in the community came from the family. Today, however, whatever individuals achieve is usually assessed on its own merit, and family has little relevance. Individuals make it or don't make it essentially on their own. A sociologist describes another way in which the American family has changed. Today, in the Western world, the major burdens that are a part of the family system are emotional ones. But in the 19th century the family was much more involved with economic needs and tasks; family and relatives were valued for providing assistance during crisis.

单选题第二篇 Can Buildings Be Designed to Resist Terrorist Attack In the aftermath of the terrorist attack on the World Trade Center, structural engineers are trying hard to solve a question that a month ago would have been completely unthinkable: Can building be designed to withstand catastrophic blasts inflicted by terrorists? Ten days after the terrorist attacks on the twin towers, structural engineers from the University at Buffalo and the Multidisciplinary Center for Earthquake Engineering Research (MCEER) headquartered at UB traveled to ground zero as part of a project funded by the National Science Foundation. Visiting the site as part of an MCEER reconnaissance visit, they spent two days beginning the task of formulating ideas about how to design such structures and searching for clues on how to do so in buildings that were damaged, but still are standing. "Our objective in visiting ground zero was to go and look at the buildings surrounding the World Trade Center, those buildings that are still standing, but that sustained damage," said M. Bruneau, Ph.D. "Our immediate hope is that we can develop a better understanding as to why those buildings remain standing, while our long-term goal is to see whether earthquake engineering technologies can be married to existing technologies to achieve enhanced performance of buildings in the event of terrorist attacks." he added. Photographs taken by the investigators demonstrate in startling detail the monumental damage inflicted on the World Trade Center towers and buildings in the vicinity. One building a block away from the towers remains standing, but was badly damaged. "This building is many meters away from the World Trade Center and yet we see a column there that used to be part of that building", explained A. Whittaker, Ph. D. "The column became a missile that shot across the road, through the window and through the floor." The visit to the area also revealed some surprises, according to the engineers. For example, the floor framing systems in one of the adjacent buildings was quite rugged, allowing floors that were pierced by tons of falling debris to remain intact. "Highly redundant ductile framing systems may provide a simple, but robust strategy for blast resistance." he added. Other strategies may include providing alternate paths for gravity loads in the event that a load-bearing column fails. "We also need a better understanding of the mechanism of collapse", said A. Whittaker. "We need to find out what causes a building to collapse and bow you can predict it." A. Reinhorn, Ph.D. noted that "earthquake shaking has led to the collapse of many buildings in the past. It induces dynamic response and extremely high stresses and deformations in structural components. Solutions developed for earthquake-resistant design may be directly applicable to blast engineering and terrorist-resistant design. Part of our mission now at UB is to transfer these solutions and to develop new ones where none exist at present."

单选题Sports Star Yao Ming If Yao Ming is not the biggest sports star in the world, he is almost certainly the tallest. At 2.26m, he is the tallest player in the National Basketball Association (NBA) and holds the record as the most towering Olympian ever to compete in the Games. But what really stands out about the giant center is his celebrity (名气). Few, if any, Chinese athletes are as well-known as Yao around the world. People across the globe are fascinated with Yao, not only for his basketball prowess (杰出的才能) but also for being a symbol of international commerce. When Yao joined the Houston Rockets as the No. 1 pick in the 2002 NBA draft (选拔), he was the first international player ever to be selected first. His assets on the court are clear enough—no NBA player of his size has ever possessed his mobility, so he is a handful (难对付的人) for opponents on either end of the court. But what makes Yao invaluable to the Rockets organization is his role as a global citizen and as a bridge to millions of potential basketball fans in China. When it was announced in February that Yao would miss the rest of the NBA season and possibly the Olympics with a stress fracture (骨折) in his left foot, a collective shudder (震动) spread across China. After considerable debate and discussion, Yao opted to get his foot surgically treated in an operation that placed several tiny screws across the bone, to offer his overburdened foot more support. The surgery was a success, and though the estimated four-month recovery period will leave him little time to prepare with Team China, Yao has vowed to be ready for the Beijing Olympics. Yao wrapped up a 10-day trip to China, where he underwent a series of traditional Chinese medicine (TCM) treatments, hoping to accelerate his recovery process. Western experts are generally skeptical of TCM"s benefits, although new research from the University of Rochester suggests that a certain compound derived from shellfish may indeed stimulate bone repair. "There is no reason to dismiss TCM," Yao told a press conference in Beijing. "It"s been used in our country for thousands of years. I don"t think that it"s short on science."

单选题{{B}}第二篇{{/B}} {{B}}Why They Travel?{{/B}} Scholars and students have always been great travellers. The official case for “academic mobility” is now often stated in impressive terms as a fundamental necessity for economic and social progress in the world, and debated in the corridors of Europe, but it is certainly nothing new. Serious students were always ready to go abroad in search of the most stimulating teachers and the most famous academies; in search of the purest philosophy, the most effective medicine, the likeliest road to gold. Mobility of this kind meant also mobility of ideas, their transference across frontiers, their simultaneous impact upon many groups of people. The point of learning is to share it, whether with students or with colleagues; one presumes that only eccentrics have no interest in being credited with a startling discovery, or a new technique. It must also have been reassuring to know that other people in other parts of the world were about to make the same discovery or were thinking along the same lines, and that one was not quite alone, confronted by inquisition, ridicule or neglect. In the twentieth century, and particularly in the last 20 years, the old footpaths of the wandering scholars have become vast highways. The vehicle which has made this possible has of course been the aeroplane, making contact between scholars even in the most distant places immediately feasible, and providing for the very rapid transmission of knowledge. Apart from the vehicle itself, it is fairly easy to identify the main factors which have brought about the recent explosion in academic movement. Some of these are purely quantitative and require no further mention: there are far more centres of learning, and a far greater number of scholars and students. In addition one must recognise the very considerable multiplication of disciplines, particularly in the sciences, which by widening the total area of advanced studies has produced an enormous number of specialists whose particular interests are precisely defined. These people would work in some isolation if they were not able to keep in touch with similar isolated groups in other countries. Frequently these specialisations lie in areas where very rapid developments are taking place, and also where the research needed for developments is extremely costly and takes a long time. It is precisely in these areas that the advantages of collaboration and sharing of expertise appear most evident. Associated with this is the growth of specialist periodicals, which enable scholars to become aware of what is happening in different centres of research and to meet each other in conferences and symposia. From these meetings come the personal relationships which are at the bottom of almost all formalized schemes of cooperation, and provide them with their most satisfactory stimulus. But as the specialisations have increased in number and narrowed in range, there had been an opposite movement towards interdisciplinary studies. These owe much to the belief that one cannot properly investigate the incredibly complex problems thrown up by the modern world, and by recent advances in our knowledge along the narrow front of a single discipline. This trend has led to a great deal of academic contact between disciplines, and a far greater emphasis on the pooling of specialist knowledge, reflected in the broad subjects chosen in many international conferences.
