(20 points)* (分数:1.00)_三、Section Reading(总题数:4,分数:4.00)Science has long had an uneasy relationship with other aspects of culture. Think of Gallileos 17th-century trial for his rebelling belief

    14、 before the Catholic Church or poet William Blakes harsh remarks against the mechanistic worldview of Isaac Newton. The schism between science and the humanities has, if anything, deepened in this century. Until recently, the scientific community was so powerful that it could afford to ignore its cr

    15、itics but no longer. As funding for science has declined, scientists have attacked “antiscience“ in several books, notably Higher Superstition, by Paul R. Gross, a biologist at the University of Virginia, and Norman Levitt, a mathematician at Rutgers University; and The Demon-Haunted World, by Carl

    16、Sagan of Cornell University. Defenders of science have also voiced their concerns at meetings such as“ The Flight from Science and Reason,“ held in New York City in 1995,and “Science in the Age of (Mis) information, “which assembled last June near Buffalo. Antiscience clearly means different things

    17、to different people. Gross and Levitt find fault primarily with sociologists, philosophers and other academics who have questioned sciences objectivity. Sagan is more concerned with those who believe in ghosts, creationism and other phenomena that contradict the scientific worldview. A survey of new

    18、s stories in 1996 reveals that the antiscience tag has been attached to many other groups as well, from authorities who advocated the elimination of the last remaining stocks of smallpox virus to Republicans who advocated decreased funding for basic research. Few would dispute that the term applies

    19、to the Unabomber, whose manifesto published in 1995, scorns science and longs for return to a pretechnological Utopia. But surely that does not mean environmentalists concerned about uncontrolled industrial growth are antiscience, as an essay in US News on the contrary, many of them lie deep in the

    20、interior of a plate. Most of the hot spots move only slowly, and in some cases the movement of the plates past them has left trails of dead volcanoes. The hot spots and their volcanic trails are milestones that mark the passage of the plates. That the plates are moving is now beyond dispute. Africa

    21、and South America, for example, are moving away from each other as new material is injected into the seafloor between them. The complementary coastlines and certain geological features that seem to span the ocean are reminders of where the two continents were once joined. The relative motion of the

    22、plates carrying these continents has been constructed in detail, but the motion of one plate with respect to another cannot readily be translated into motion with respect to the earths interior. It is not possible to determine whether both continents are moving in opposite directions or whether one

    23、continent is stationary and the other is drifting away from it. Hot spots, anchored in the deeper layers of the earth, provide the measuring instruments needed to resolve the question. From an analysis of the hot-spot population it appears that the African plate is stationary and that it has not mov

    24、ed during the past 30 million years. The significance of hot spots is not confined to their role as a frame of reference. It now appears that they also have an important influence on the geophysical processes that propel the plates across the globe. When a continental plate comes to rest over a hot

    25、spot, the material rising from deeper layers creates a broad dome. As the dome grows, it develops deep fissures (cracks) : in at least a few cases the continent may break entirely along some of these fissures, so that the hot spot initiates the formation of new ocean. Thus just as earlier theories h

    26、ave explained the mobility of the continents, so hot spots may explain their mutability( inconstancy ). (分数:1.00)(1). The author believes that _.(分数:0.25)A.the motion of the plates corresponds to that of the earths interiorB.the geological theory about drifting plates has been proved to be trueC.the

    27、 hot spots and the plates move slowly in opposite directionsD.the movement of hot spots proves the continents are moving apart(2).That Africa and South America were once joined can be deduced from the fact that _.(分数:0.25)A.the two continents are still moving in opposite directionsB.they have been f

    28、ound to share certain geological featuresC.the African plate has been stable for 30 million yearsD.over 100 hot spots are scattered all around the globe(3). The hot-spot theory may prove useful in explaining _.(分数:0.25)A.the structure of the African platesB.the revival of dead volcanoesC.the mobilit

    29、y of the continentsD.the formation of new oceans(4). The passage is mainly about_.(分数:0.25)A.the features of volcanic activitiesB.the importance of the theory about drifting platesC.the significance of hot spots in geophysical studiesD.the process of the formation of volcanoesOf all the components o

    30、f a good night s sleep, dreams seem to be least within our control. In dreams, a window opens into a world where logic is suspended and dead people speak. A century ago, Freud formulated his revolutionary theory that dreams were the disguised shadows of our unconscious desires and fears; by the late

    31、 1970s, neurologists had switched to thinking of them as just “mental noise“the random byproducts of the neural - repair work that goes on during sleep. Now researchers suspect that dreams are part of the mind s emotional thermostat, regulating moods while the brain is “off - line.“ And one leading

    32、authority says that these intensely powerful mental events can be not only harnessed but actually brought under conscious control, to help us sleep and feel better. “It s your dream,“ says Rosalind Cartwright, chair of psychology at Chicago s Medical Center. “If you don t like it, change it.“ Eviden

    33、ce from brain imaging supports this view. The brain is as active during REM (rapid eye movement) sleepwhen most vivid dreams occuras it is when fully awake, says Dr. Eric Nofzinger at the University of Pittsburgh. But not all parts of the brain are equally involved; the limbic system (the “emotional

    34、 brain“) is especially active, while the prefrontal cortex (the center of intellect and reasoning) is relatively quiet. “We wake up from dreams happy or depressed, and those feelings can stay with us all day,“ says Stanford sleep researcher Dr. William Dement. The link between dreams and emotions sh

    35、ows up among the patients in Cartwright s clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day. Because our conscious mind is occupied with daily life

    36、 we don t always think about the emotional significance of the day s eventsuntil, it appears, we begin to dream. And this process need not be left to the unconscious. Cartwright believes one can exercise conscious control over recurring bad dreams. As soon as you awaken, identify what is upsetting a

    37、bout the dream. Visualize how you would like it to end instead; the next time it occurs, try to wake up just enough to control its course. With much practice people can learn to, literally, do it in their sleep. At the end of the day, there s probably little reason to pay attention to our dreams at

    38、all unless they keep us from sleeping or “we wake up in a panic,“ Cartwright says. Terrorism, economic uncertainties and general feelings of insecurity have increased people s anxiety. Those suffering from persistent nightmares should seek help from a therapist. For the rest of us, the brain has its

    39、 ways of working through bad feelings. Sleep or rather dreamon it and youll feel better in the morning. (分数:1.00)(1).Researchers have come to believe that dreams(分数:0.20)A.can be modified in their courses.B.are susceptible to emotional changes.C.reflect our innermost desires and fears.D.are a random

    40、 outcome of neural repairs(2).By referring to the limbic system, the author intends to show(分数:0.20)A.its function in our dreams.B.the mechanism of REM sleep.C.the relation of dreams to emotions.D.its difference from the prefrontal cortex.(3).The negative feelings generated during the day tend to(分数

    41、:0.20)A.aggravate in our unconscious mind.B.develop into happy dreams.C.persist till the time we fall asleep.D.show up in dreams early at night.(4).Cartwright seems to suggest that(分数:0.20)A.waking up in time is essential to the ridding of bad dreams.B.visualizing bad dreams helps bring them under c

    42、ontrolC.dreams should be left to their natural progression.D.dreaming may not entirely belong to the unconscious.(5).What advice might Cartwright give to those who sometimes have bad dreams?(分数:0.20)A.Lead your life as usual.B.Seek professional help.C.Exercise conscious controlD.Avoid anxiety in the

    43、 daytimeCould the bad old days of economic decline be about to return Since OPEC agreed to supply-cuts in March, the price of crude oil has jumped to almost $ 26 a barrel, up from less than $10 last December. This near-tripling of oil prices calls up scary memories of the 1973 oil shock, when prices

    44、 quadrupled, and 197980, when they also almost tripled. Both previous shocks resulted in double- digit inflation and global economic decline. So where are the headlines warning of gloom and doom this time? The oil price was given another push up this week when Iraq suspended oil exports. Strengtheni

    45、ng economic growth, at the same time as winter grips the northern hemisphere, could push the price higher still in the short term. Yet there are good reasons to expect the economic consequences now to be less severe than in the 1970s. In most countries the cost of crude oil now accounts for a smalle

    46、r share of the price of petrol than it did in the 1970s. In Europe, taxes account for up to four-fifths of the retail price, so even quite big changes in the price of crude have a more muted effect on pump prices than in the past. Rich economies are also less dependent on oil than they were, and so

    47、less sensitive to swings in the oil price. Energy conservation, a shift to other fuels and a decline in the importance of heavy, energy-intensive industries have reduced oil consumption. Software, consultancy and mobile telephones use far less oil than steel or car production. For each dollar of GDP ( in constant prices) rich economies now use nearly 50% less oil than in 1973. The OECD es
