These are volcanoes so explosive that they burst open in a single big crack，leaving behind a vast hole，the caldera. Yellowstone obviously was of this second type，but Christiansen couldn＇t find the caldera anywhere. Just at this time NASA decided to test some new highaltitude cameras by taking photographs of Yellowstone. A thoughtful official passed on some of the copies to the park authorities on the assumption that they might make a nice blowup for one of the visitors＇ centers. As soon as Christiansen saw the photos，he realized why he had failed to spot the caldera。 almost the whole million acres—was caldera. The explosion had left a hole more than forty miles across—much too huge to be seen from anywhere at ground level. At some time in the past Yellowstone must have blown up with a violence far beyond the scale of anything known to humans. 58. What puzzled Christiansen when he was studying Yellowstone？ A. Its plicated geographical features. B. Its everlasting influence on tourism. C. The mysterious history of the park. D. The exact location of the volcano. 59. What does the secondparagraph mainly talk about？ A. The shapes of volcanoes. B. The impacts of volcanoes. C. The activities of volcanoes. D. The heights of volcanoes. 60. What does the underlined word “blowup“ in the last paragraph most probably mean？ A. Hotair balloon. B. Digital camera. C. Big photograph. D. Bird＇s view. C Who cares if people think wrongly that the Internet has had more important influences than the washing machine? Why does it matter that people are more impressed by the most recent changes? It would not matter if these misjudgments were just a matter of people＇s opinions. However, they have real impacts, as they result in misguided use of scarce resources. The fascination with the ICT(Information and Communication Technology) revolution, represented by the Internet, has made some rich countries wrongly conclude that making things is so “yesterday“ that they should try to live on ideas. This belief in “postindustrial society“ has led those countries to neglect their manufacturing sector(制造業(yè)) with negative consequences for their economies. Even more worryingly, the fascination with the Internet by people in rich countries has moved the international munity to worry about the “digital divide“ between the rich countries and the poor countries. This has led panies and individuals to donate money to developing countries to buy puter equipment and Internet facilities. The question, however, is whether this is what the developing countries need the most. Perhaps giving money for those less fashionable things such as digging wells, extending electricity networks and making more affordable washing machines would have improved people＇s lives more than giving every child a laptop puter or setting up Internet centres in rural villages, I am not saying that those things are necessarily more important, but many donators have rushed into fancy programmes without carefully assessing the relative longterm costs and benefits of alternative uses of their money. In yet another example, a fascination with the new has led people to believe that the recent changes in the technologies of munications and transportation are so revolutionary that now we live in a “borderless world“. As a result, in the last twenty years or so, many people have e to believe that whatever change is happening today is the result of great technological progress, going against which will be like trying to turn the clock back. Believing in such a world, many governments have put an end to some of the very necessary regulations on crossborder flows of capital, labour and goods, with poor results. Understanding technological trends is very important for correctly designing economic policies, both at the national and the international levels, and for making the right career choices at the individual level. However, our fascination with the latest, and our under valuation of what has already bee mon, can, and has, led us in all sorts of wrong directions. 61. Misjudgments on the influences of new technology can lead to __________. A. a lack of confidence in technology B a slow progress in technology C. a conflict of public opinions D. a waste of limited resources 62. The example in Paragraph 4 suggests that donators should __________. A. take people＇s essential needs into account B. make their programmes attractive to people C. ensure that each child gets financial support D provide more affordable internet facilities 63. What has led many governments to remove necessary regulations? A. Neglecting the impacts of technological advances. B. Believing that the world has bee borderless. C. Ignoring the power of economic development. D. Overemphasizing the role of international munication. 64. What can we learn from the passage? A. People should be encouraged to make more donations. B. Traditional technology still has a place nowadays. C. Making right career choices is crucial to personal success. D. Economic policies should follow technological trends.
