共享题干题 (二)Earthquake根据以下材料，回答问题。 Earthquake may rightly be ranked as one of the most destructive forces known to man: since records began to be written down, it has been estimated that earthquake-related fatalities have numbered in the million, and that earthquake-related destruction has been beyond calculation. The greater part of such damage and loss of life has been due to collapse of buildings and the effects of rockslides, floods, fire, disease, tsunamis (gigantic sea waves), and other observable events resulting from earthquake, rather than from the quakes themselves. The great majority of all earthquakes occur in two specific geographic areas. One such area covers the Pacific Ocean and its bordering landmasses. The other extends from the East Indians to the Atlas Mountains, including the Himalayas, Iran, Turkey, and the Alpine regions. It is in there two great belts or zones that ninety percent of all earthquakes take place; they say, however, happen anywhere at any time. This element of the unknown has for centuries added greatly to the dread and horror surrounding earthquakes, but in recent times there have been indications that earthquake forecast may be possible. By analyzing changes in animal behavior, pattems of movements in the earth's shell,variations in the earth's force of attraction, and the frequency with which minor earth shakes are observed, scientists have shown increasing success in expecting when and where earthquakes will strike. As a result, a worldwide earthquake warning network is already in operation and has helped to prepare for (and thus lessen) the vast destruction that might otherwise have been totally unexpected. It is doubtful that man will ever be able to control earthquakes and get rid of their destructiveness altogether, but as how and why earthquakes happen become better understood, man will become more and more able to deal with their possible damage before they occur.1.[不定向选择题]Man's research on earthquake forecast at present is to __________。A.reduce the loss from earthquake disasters. B.lower the frequency of earthquakes. C.release the energy that causes earthquakes. D.analyze the relationship between different earthquakes. 2.[不定向选择题]Which of the following statements is true according to the passage?A.Earthquake destruction is declining. B.Earthquake forecast is improving. C.Man is no longer fearful of earthquakes. D.Man is capable of conquering earthquakes.

1.参考答案：A
参考解析：人类目前关于地震预测的研究是为了___________ 。利用题干关键词可以定位到文中第三段，该段提到了“全球地震预警系统可以帮助应对(因此减少)突如其来的地震造成的巨大伤害”，因此A选项中的reduce是对原文lessen的最好阐释。
2.参考答案：B
参考解析：题干：根据文章所述，下列哪一项是对的?文章的第三段和第四段的主题思想都围绕着“scientists have shown increasing Success in expecting when and where earthquakes will strike”，即，科学家们已经能够越来越成功地预测地震发生的时间和地点了。3.[不定向选择题]The phrase "this element of the unknown" (Paragraph 3) refers to __________.A.the extension of earthquake zones. B.the percentage of earthquake occurrences. C.when and where earthquakes may occur. D.what big damage earthquakes may cause.
