单选题The ocean bottom—a region nearly 2.5 times greater than the total land area of the Earth—is a vast frontier that even today is largely unexplored and uncharted. Until about a century ago, the deep-ocean floor was completely inaccessible , hidden beneath waters averaging over 3,600 meters deep. Totally without fight and subjected to intense pressures hundreds of times greater than at the Earth"s surface, the deep-ocean bottom is a hostile environment to humans, in some ways as forbidding and remote as the void of outer space . Although researchers have taken samples of deep-ocean rocks and sediments for over a century, the first detailed global investigation of the ocean bottom did not actually start until 1968, with the beginning of the National Science Foundation"s Deep Sea Drilling Project (DSDP). Using techniques first developed for the offshore oil and gas industry, the DSDP"s drill ship, the Glomar Challenger, was able to maintain a steady position on the ocean"s surface and drill in very deep waters, extracting samples of sediments and rock from the ocean floor. The Glomar Challenger completed 96 voyages in a 15-year research program that ended in November 1983. During this time, the vessel logged 600,000 kilometers and took almost 20,000 core samples of seabed sediments and rocks at 624 drilling sites around the world. The Glomar Challenger"s core samples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago and to calculate what it will probably look like millions of years in the future. Today, largely on the strength of evidence gathered during the Glomar Challenger"s voyages, nearly all earth scientists agree on the theories of plate tectonics and continental drift that explain many of the geological processes that shape the Earth. The cores of sediment drilled by the Glomar Challenger have also yielded information critical to understanding the world"s past climates. Deep-ocean sediments provide a climatic record stretching back hundreds of millions of years, because they are largely isolated from the mechanical erosion and the intense chemical and biological activity that rapidly destroy much land-based evidence of past climates. This record has already provided insights into the patterns and causes of past climatic change-information that may be used to predict future climates.

单选题Social control refers to social processes, planned or unplanned, by which people are taught, persuaded, or forced to conform to norms. In every society, some punishments or negative sanctions are established for deviant behavior. Without deviant behavior there would not be need for social control and without social control there would not be a way of recognizing the boundary between the acceptable and the unacceptable. Social control may be either formal or informal. Informal mechanisms include expressions of disapproval by significant others and withholding of positive rewards for disapproved behavior. Most people internalize norms in the course of socialization. This is any group's most powerful protection against deviance, in that the individual's own conscience operates as an agent of social control. When informal sanctions fail, formal agents of social control may be called upon. In contemporary society, such formal agents and agencies include psychiatry and other mental health professions; mental hospitals; police and courts of law; prisons; and social welfare agencies. All these formal agents function to limit, correct, and control violation of norms. Conflict theorists would also point out that social control agents and systems tend, in any society, to serve the interests of powerful groups and to enforce the norms most beneficial to those who make the rules and who, therefore, define unacceptable behavior. Social control, whether formal or informal, has a dual function. First, it punishes the wrongdoer and reaff'irms the boundaries of acceptable behavior. Second, and less recognized, it regulates the manner in which deviants are treated.

单选题Mass Communication Technology The single greatest shift in the history of mass-communication technology occurred in the 15th century and was well described by Victor Hugo in a famous chapter of Notre-Dame de Paris. It was a Cathedral. On all parts of the giant building, statuary and stone representations of every kind, combined with huge windows of stained glass, told the stories of the Bible and the saints, displayed the intricacies of Christian theology, adverted to the existence of highly unpleasant demonic winged creatures, referred diplomatically to the majesties of political power, and in addition, by means of bells in bell towers, told time for the benefit of all of Pairs and much of France. It was an awesome engine of communication. Then came the transition to something still more awesome. The new technology of mass communication was portable, could sit on you table, and was easily replicable, and yet, paradoxically, contained more information, more systematically presented, than provided no bells and could not tell time, the over-all superiority of the new invention was unmistakable. In the last ten or twenty years, we have been undergoing a more or less equivalent shift—this time to a new life as a computer-using population. The gain in portability, capability, ease, orderliness, accuracy, reliability, and information-storage over anything achievable by pen scribbling, typewriting, and cabinet filing is recognized by all. The progress for civilization is undeniable and, cathedral divided people into two groups, one of which prospered, while the other lapsed into gloom, the computer"s triumph has also divided the human race. You have only to bring a computer into a room to see that some people begin at once to buzz with curiosity and excitement, sit down to conduct experiments, ooh and ah at the boxes and beeps, and master the use of the computer or a new program as quickly as athletes playing a delightful new game. But how difficult it is—how grim and frightful!—for the other people, the defeated class, whose temperament does not naturally respond to computers. The machines whirrs and glows before them and their faces twitch. They may be splendidly educated, as measured by book-reading, yet their instincts are all wrong, and no amount of manual-studying and mouse-clicking will make them right, if the aptitudes are missing, little can be done, and misery is guaranteed. Is the computer industry aware that computers have divided mankind into two new, previously unknown classes, the computer personalities and the non-computer personalities? Yes, the industry knows this. Vast sums have been expended in order to adapt the computer to the limitations of non-computer personalities. Apple"s Macintosh, with its zooming animations and pull-down menus and little pictures of file folders and watch faces and trash cans, pointed the way. Such seductions have soothed the apprehensions of a certain number of the computer-averse. This spring, the computer industry"s efforts are reaching a culmination of sorts. Microsoft, Bill Gate"s giant corporation, is to bring out a program package called Microsoft Bob, designed by Mr. Gates" wife, Melinda French, and intended to render computer technology available even to people who are openly terrified of computers. Bob"s principle is to take the several tasks of operating a computer, rename them in a folksy style, and assign to them the images of an ideal room in an ideal home, with furniture and bookshelves, and with chummy cartoon helpers ("Friends of Bob") to guide the computer user over the rough spots, and, in that way, simulate an atmosphere that feels nothing like computers.
