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 and South America, for example, are moving away from each other as new material is injected into the sea floor between them. The plementary 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 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 earth39。s volcanoes, they are not always found at the boundaries of the great drifting plates that make up the earth39。 new pursuit of spacious living \[D\] it elaborates the delayed effects of yesterday39。s growth rate dropped during the 1970s, to 18. 5 percentlittle more than two thirds the 1960s39。s head counting. Altogether, the US population rose in the 1970s by million peoplenumerically the third largest growth ever recorded in a single decade. Even so, that gain adds up to only percent, lowest in American annual records except for the Depression years. Americans have been migrating south and west in larger numbers since World War II, and the pattern still prevails. Three sunbelt statesFlorida, Texas and Californiatogether had nearly 10 million more people in 1980 than a decade earlier. Among large cities, San Diego moved from 14th to 8th and San Antonio from 15th to 10thwith Cleveland and Washington, ., dropping out of the top 10. Not all that shift can be attributed to the movement out of the snow belt, census officials say. Nonstop waves of immigrants played a role, tooand so did bigger crops of babies as yesterday39。s attitude toward the issue of science vs. antiscience is. \[A\] impartial\[B\] subjective \[C\] biased\[D\] puzzling Passage 4 Emerging from the 1980 census is the picture of a nation developing more and more regional petition, as population growth in the Northeast and Midwest reaches a near standstill.

Sagan is more concerned with those who believe in ghosts, creationism and other phenomena that contradict the scientific worldview. A survey of news 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 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 amp。s 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 munity was so powerful that it could afford to ignore its criticsbut 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。s anticipation \[C\] meet the expectation of business people \[D\] fail to reflect the true state of economy 17. The author raises the question what about pain without gain? because. \[A\] he questions the truth of no gain without pain \[B\] he does not think the productivity revolution works \[C\] he wonders if the official statistics are misleading \[D\] he has conclusive evidence for the revival of businesses 18. Which of the following statements is NOT mentioned in the passage? \[A\] Radical reforms are essential for the increase of productivity. \[B\] New ways of anizing workplaces may help to increase productivity. \[C\] The reduction of costs is not a sure way to gain longterm profitability. \[D\] The consultants are a bunch of goodfornothings. Passage 3 Science has long had an uneasy relationship with other aspects of culture.

But what about pain without gain? Everywhere you go in America, you hear tales of corporate revival. What is harder to establish is whether the productivity revolution that businessmen assume they are presiding over is for real. The official statistics are mildly discouraging. They show that, if you lump manufacturing and services together, productivity has grown on average by % since 1987. That is somewhat faster than the average during the previous decade. And since 1991, productivity has increased by about 2% a year, which is more than twice the 19781987 averages. The trouble is that part of the recent acceleration is due to the usual rebound that occurs at this point in a business cycle, and so is not conclusive evidence of a revival in the underlying trend. There is, as Robert Rubin, the treasury secretary, says, a disjunction between the mass of business anecdote that points to a leap in productivity and the picture reflected by the statistics. Some of this can be easily explained. New ways of anizing
