单选题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 must 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.

单选题 When I became president of the University of Michigan, affirmative action in higher education was under siege. Buoyed by a successful lawsuit against the University of Texas law school's admission policy and by ballot initiatives such as California's Proposition 209, which outlawed race as a factor in college admissions, the opponents set their sights on affirmative-action programs at college across the country. The rumor that Michigan would be the next target in this campaign turned out to be correct. I believed strongly that we had no choice but to mount the best legal defense ever for diversity in higher education and take special efforts to explain this complex issue, in simple and direct language, to the American public. There are many mispereeptions about how race and ethnieity are considered in college admissions. Competitive colleges and universities are always looking for a mix of students with different experiences and backgrounds — academic, geographic, international, socioeconomic, athletic, public-service oriented, and, yes, racial and ethnic. It is true that in sorting the initial rush of applications, large universities will give "points" for various factors in the selection process in order to ensure fairness as various officers review applicants. Opponents of Michigan's undergraduate system complain that an applicant is assigned more points for being black, Hispanic, or Native American than for having a perfect SAT score. This is true, but it trivializes the real issue: whether, in principle, race and ethnicity are appropriate considerations. The simple fact about the Michigan undergraduate policy is that it gives overwhelming weight to traditional academic factors — some 110 out of a total of 150 points. After that, there are some 40 points left for other factors, of which 20 can be allocated for race or socioeconomic status. Race has been a defining element of the American experience. The historic Brown v. Board of Education decision is almost 50 years old, yet metropolitan Detroit is more segregated now than it was in 1960. The majority of students who each year arrive on a campus like Michigan graduated from virtually all-white or all-black high schools. The campus is their first experience living in an integrated environment. Diversity is not merely a desirable addition to a well-rounded education. It is as essential as the study of the Middle Ages, of international politics, and of Shakespeare. For our students to better understand the diverse country and world they inhabit, they must be immersed in a campus culture that allows them to study with, argue with, and become friends with students who may be different from them. It broadens the mind, and the intellect-essential goals of education. Reasonable people can disagree about affirmative action. But it is important that we do not lose the sense of history, the compassion and the largeness of vision that defined the best of the civil-rights era, which has given rise to so much of what is good about America today.

单选题The blue, mystic Lake Elsinore lies in an inland California valley which is teeming and steaming with hot springs. Rimmed by shaggy mountains whose forested crests are reflected in its clear waters, Lake Elsinore is the very personification of peace-but on it rests the curse of Tondo. The lake has had a colorful history. Much of it lies buried in legend, and it is difficult to separate fact from fiction. There have been stories of underground volcanoes on the lake bottom, erupting, killing fish and discoloring the water. There have been stories of a playful sea serpent that lived in its depths. Long noted for its scenic beauty and health-giving waters, the lake was a famous resort in the Nineties. But long before the first white man had set foot along the shore of the lake, this part of California had been the home of the Soboba Indians. Their chief was Tondo, a stern and unforgiving man. He had a daughter, Morning Star, who was in love with Palo, son of the chief of the Palas, a neighboring tribe. The Sobobas and Palas were sworn enemies. For a time the lovers met secretly. Then one day they were discovered by Tondo. His rage was terrible to behold. He forbade the lovers ever to meet again. Morning Star tried in every way to appease her father's anger, to soften his heart toward Palo. But in time she saw that it was useless; that he would never give his consent to their marriage. Vowing that they would never be separated, the Indian maid and her lover walked hand in hand into the lake, as the dreary November sun cast long shadows on the land. They were followed by a group of orphan children whom Morning Star had befriended. All walked into the lake, singing the mournful death song of their people, while Tondo stood on the shore and cursed the lovers, cursed the blue water into which they all walked to their death. Ever since that day it would seem that a jinx has been laid over Lake Elsinore. Old-timers tell of a great upheaval in the lake which caused water to spout into the air like a geyser and turn blood-red. Later, it became known that three hundred springs of boiling mud and water were born in the valley during that upheaval. The springs reeked with sulphur. For many years after this phenomenon the lake remained peaceful. Then boats were overturned for no apparent reason, and few of their occupants ever returned to tell the story. This continued for several years. At the same time, strong swimmers dived into the lake never to reappear. In 1833 and again in 1846, fish in the lake suddenly died. In the spring of 1850 came the Battle of the Gnats. They bred in the water of the lake and swarmed over the land. They invaded the countryside until the harassed inhabitants called for help. And in July 1951, the sky-blue waters of the lake vanished like mist before a noonday sun. When the bottom was laid bare there was no trace of a volcano, the bottomless pits, or the other disturbances of legend or fact. The copious winter rains of 1951-52 have replenished the lake. But what menace does its haunting beauty hold today? For tomorrow? The once mighty Sobobas are few now. But the old men swear that their ancestors still haunt the lake. They nod grizzled head and murmur that the Great Tondo's curse will forever remain upon the lake. Only Time, the wise and silent one, can tell.
