单选题 Education is one of the key words of our time. A man, without an education, many of us believe, is an unfortunate victim of adverse circumstances deprived of one of the greatest twentieth-century opportunities. Convinced of the importance of education, modern states "invest" in institutions of learning to get back "interest" in the form of a large group of enlightened young men and women who are potential leaders. Education, with its cycles of instruction so carefully worked out, is punctuated by textbooks--those purchasable wells of wisdom--what would civilization be like without its benefits? So much is certain: that we would have doctors and preachers, lawyers and defendants, marriages and births; but our spiritual outlook would be different. We would lay less stress on "facts and figures" and more on a good memory, on applied psychology, and on the capacity of a man to get along with his fellow citizens. If our educational system were fashioned after its bookless past we would have the most democratic form of "college" imaginable. Among the people whom we like to call savages all knowledge inherited by tradition is shared by all; it is taught to every member of the tribe so that in this respect everybody is equally equipped for life. It is the ideal condition of the "equal start" which only our most progressive forms of modem education try to regain. In primitive cultures the obligation to seek and to receive the traditional instruction is binding to all. There are no "illiterates"--if the term can be applied to people without a script--while our own compulsory school attendance became law in Germany in 1642, in France in 1806, and in England 1876, and is still non-existent in a number of "civilized" nations. This shows how long it was before we deemed it necessary to make sure that 'all our children could share in the knowledge accumulated by the "happy few" during the past centuries. Education in the wilderness is not a matter of monetary means. All are entitled to an equal start. There is none of the hurry which, in our society, often hampers the full development of a growing personality. There, a child grows up under the ever-present attention of his parents, therefore the jungles and the grasslands know of no "juvenile delinquency". No necessity of making a living away from home results in neglect of children and no father is confronted with his inability to "buy" an education for his child.

单选题{{B}}Passage 5{{/B}} Agreeable to your request, I send you my reasons for thinking that our northeast storms in North America begin first, in point of time, in the southwest parts: that is to say, the air in Georgia, the farthest of our colonies to the Southwest, begins to move southwesterly before the air of Carolina, begins to move southwesterly before the air of Carolina, which is the next colony northeastward. The air of Carolina has the same motion before the air of Virginia, which lies still more northeastward, and so on northeasterly through Pennsylvania, New York, New England, & c. , quite to Newfoundland. These northeast storms are generally very violent, continue sometimes two or three days, and often do considerable damage in the harbors along the coast. They are attended with thick clouds and rain. What first gave me this idea, was the following circumstance. About twenty years ago, a few more or less, i cannot from my memory be certain, we were to have an eclipse of the moon at Philadelphia, on a Friday evening, about nine o'clock. I intended to observe it, but was prevented By a northeast storm, which came on about seven, with thick clouds as usual, that quite obscured the whole hemisphere. Yet when the post brought us the Boston newspaper, giving an account of the effects of the same storm in those parts, I found the beginning of the eclipse had been well observed there though Boston lies N.E. of Philadelphia about 400 miles. This puzzled me because the storm began with us so soon as to prevent any observation, and being a N. E. storm, I imagined it must have begun rather sooner in places farther to the northeastward than it did in Philadelphia. I therefore mentioned it in a letter to my brother who lived in Boston. And he informed me the storm did not begin with them till near eleven o'clock, so that they had a good observation of the eclipse: And upon comparing all the other accounts I received from the several colonies, of the time of the beginning of the same storm, and, since that of other storms of the same kind, I found the beginning to be always later the farther northeastward. I have not my notes with me here in England, and cannot, from memory, say the proportion of time to distance, but I think it is about an hour to every hundred miles. From thence I formed an idea of the cause of these storms, which I would explain by a familiar instance or two. Suppose a long canal of water stopped at the end by a gate. The water is quite at rest till the gate is open, then it begins to move out through the gate, the water next to that first water moves next, and so on successively, till the water at the head of the canal is in motion, which is last of all. In this case all the water moves indeed towards the gate, but the successive times of beginning motion are the contrary way, viz. from the gate backwards to the head of the canal. Again suppose the air in a chamber at rest, no current in the room till you make a fire in the chimney. Immediately the air in the chimney, being rarefied by the fire, rises, the air next the chimney flows in to supply its place, moving towards the chimney. And, in consequence, the rest of the air successively, quite back to the door. Thus to produce our northeast storms, I suppose some great heat and rarefaction of the air in or about the Gulf of Mexico. The air thence rising has its place supplied by the next more northern, cooler, and therefore denser and heavier, air. That being in motion is followed by the next more northern air, in a successive current, to which current our coast and inland ridge of mountains give the direction of northeast, as they lie N. E. and S. W.

单选题In the late 20th century, information has acquired two major utilitarian connotations. On the one hand, it is considered an economic resource, somewhat on par with other resources such as labour, material, and capital. This view stems from evidence that the possession, manipulation, and use of information can increase the cost-effectiveness of many physical and cognitive processes. The rise in information-processing activities in industrial manufacturing as well as in human problem solving has been remarkable. Analysis of one of the three traditional divisions of the economy, the service sector, shows a sharp increase in information-intensive activities since the beginning of the 20th century. By 1975 these activities accounted for half of the labour force of the United States, giving rise to the so-called information society. As an individual and societal resource, information has some interesting characteristics that separate it from the traditional notions of economic resources. Unlike other resources, information is expansive, with limits apparently imposed only by time and human cognitive capabilities. Its expansiveness is attributable to the following: (1) it is naturally diffusive; (2) it reproduces rather than being consumed through use; and (3) it can' be shared only, not exchanged in transactions. At the same time, information is compressible, both syntactically and semantically. The second perception of information is that it is an economic commodity, which helps to stimulate the worldwide growth of a new segment of national economies-the information service sector. Taking advantage of the properties of information and building on the perception of its individual and societal utility and value, this sector provides a broad range of information products and services. By 1992 the market share of the U.S. information service sector had grown to about $ 25 billion. This was equivalent to about one-seventh of the country's computer market, which, in turn, represented roughly 40 percent of the global market in computers in that year. However, the probable convergence of computers and television (which constitutes a market share 100 times larger than computers) and its impact on information services, entertainment, and education are likely to restructure the respective market shares of the information industry before the onset of the 21st century.

单选题{{B}}Passage Five{{/B}} In the 1960s, medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful events. They appreciated the tricky point that any major change can be stressful. Negative events like "serious illness of a family member" were high on the list but so were some positive life-changing events like marriage. When you take the Holmes-Rahe test you must remember that the score does not reflect how you deal with stress, it only shows how much you have chances of staying healthy. By the early 1970s, hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow the research got boiled down to a memorable message. Women's magazines ran headlines like "Stress causes illness." "If you want to stay physically and mentally healthy," the articles said, "avoid stressful events." But such simplistic advice is impossible to follow. Even if stressful events are dangerous, many, like the death of a loved one, are impossible to avoid. Moreover, any warning to avoid all stressful events is a prescription for staying away from opportunities as well as trouble. Since any change can be stressful, a person who wanted to be completely free of stress would never marry, have a child, take a new job or move. The notion that all stress makes you sick also ignores a lot of what we know about people. It assumes we're all vulnerable and passive in the face of adversity. But what about human initiative and creativity? Many come through periods of stress with more physical and mental vigor than they had before. We also know that a long time without change or challenge can lead to boredom and mental strain.
