单选题Nowadays, our society is being reshaped by information technologies—computers, telecommunications networks, and other digital systems. Of course, our society has gone through other periods of dramatic change before, driven by such innovations as the steam engine, railroad, telephone, and automobile. But never before have we experienced technologies that are evolving so rapidly, altering the constraints of time and space, and reshaping the way we communicate, learn, and think. The rapid development of digital technologies creates not only more opportunities for the society but challenges to it as well. Institutions of every stripe are grappling to respond by adapting their strategies and activities. It is no exaggeration to say that information technology is completely changing the relationship between people and knowledge. But ironically, at the most knowledge-based entities—the colleges and universities—the pace of transformation has been relatively modest. Although research has been transformed by information technology in many ways, and it is increasingly used for student and faculty communications, other higher-education functions have remained almost unchanged. For example, teaching largely continues to follow a classroom-centered, seat-based paradigm. However, some major technology aided teaching experiments are emerging, and some factors suggest that digital technologies may eventually drive significant change throughout academia. American academia has undergone significant change before. The establishment of secular education began during the 18th century and the Land-Grant College Act of 1862 resulted in another transformation. That Act created institutions serving agriculture and industries; academia was no longer just for the wealthy but charged with providing educational opportunities to the working class as well. Around the year of 1900, the introduction of graduate education began to expand the role of the university in training students for careers both scholarly and professional. Higher education has already experienced significant technology-based change, even if it currently lags other sectors in some areas. We expect that the new technology will eventually impose a profound impact on university"s teaching by freeing the classroom from its physical and temporal bounds and by providing students with access to original source materials and that new learning communities driven by information technology will allow universities to better teach students how to be critical analyzers and consumers of information. The information society has greatly expanded the need for university-level education; lifelong learning is not only a private good for those who pursue it but also a social good in terms of our nation"s ability to maintain a vibrant democracy and support a competitive workforce.

单选题It was not "the comet of the century" experts predicted it might be. However, Kohoutek has provided a bonanza of scientific information. It was first spotted 370 million miles from Earth, by an astronomer who was searching the sky for asteroids, and after whom the comet was named. Scientists who tracked Kohoutek the ten months before it passed the Earth predicted the comet would be a brilliant spectacle. But Kohoutek fell short of these predictions, disappointing millions of amateur sky watchers, when it proved too pale to be seen with the unaided eye. Researchers were very happy nonetheless with the new information they were able to glean from their investigation of file comet. Perhaps the most significant discovery was the identification of two important chemical compounds -- methyl cyanide and hydrogen cyanide -- never before seen in comets, but found it the far reaches of interstellar space. This discovery revealed new clues about the origin of comets. Most astronomers agree that comets are primordial remnants from the formation of the solar system, but whether they were born between Jupiter and Neptune or much farther out toward interstellar space has been the subject of much debate. If compounds no more complex than ammonia and methane, key components of Jupiter, were seen in comets, it would suggest that comets form within the planetary orbits. But more complex compounds, such as the methyl cyanide found in Kohoutek, point to formation far beyond the planets; there the deep freeze of space has kept them unchanged.
