The costs associated with natural disasters are increasing rapidly. As a result, officials in government and industry have focused more attention on disasters and their effects. The White House Office of Science and Technology Policy has estimated that disasters cost the country, about 1 billion per week. Hurricane Andrew, the Midwest flood of 1993, and the Hanshin earthquake have shown that individual disasters can cost tens if not hundreds of billions of dollars. This increasing cost has resulted in greater funding from government and industry for the development of technologies related to disaster prediction, and has led to more research into the effective use of predictive information. The insurance industry has long been aware of the dangers of natural disasters; the 1906 earth-quake in San Francisco, California, bankrupted scores of insurance companies. But the industry has focused particular attention on disaster prediction in recent years, as spiraling costs revealed that many companies had underestimated their financial exposure. For instance, prior to Hurricane An-drew in 1992, many insurance experts thought that the worst hurricane possible would do no more than 8 billion in damages Io the industry. The damages caused by Hurricane Andrew, estimated at about 17 billion, shattered these beliefs. Today, estimates of worst-case disaster scenarios approach 100 billion. The insurance industry has therefore increased its support for research into disaster prediction. One such effort involves a number of companies that have joined together to support the Bermuda-based Risk Prediction Initiative, which funds disaster research. The expectation is that the resulting information will place the industry on a more solid foundation to make decisions about the risk of future disasters. The industry has also lobbied for the government to bear some of the financial burden of disaster insurance. Such a program already exists for flood insurance, set up in the late 1960s by the federal government to insure flood-prone areas. These types of programs, effectively implemented, could be increasingly necessary in the future to make insurance available in areas prone to disasters. Because the stakes are so high, the science of disaster prediction has a bright future. The various projects and programs illustrate that disaster prediction is a topic of concern to scientists and policy-makers alike. Hurricanes, tornadoes, floods, earthquakes, tsunamis, and volcanoes all show that the effective use of disaster predictions not only requires advanced technology but also requires that society consider the entire process of prediction—forecasts, communication, and use of information. Because they cannot predict the future with certainty, and because much remains to be learned, scientists warn that society must understand the limits of scientific predictions and be prepared to employ alternatives. Wisely used, however, disaster prediction has the potential to reduce society"s vulnerability to natural disasters.
单选题 The result of the increasing costs in natural disasters is
【正确答案】 D
【答案解析】解析:事实细节题。文章首段末句指出"不断增加的花费让政府和企业加大投资,致力于开发与灾难预测相关的技术,更多的研究也集中在预测信息的有效使用上"。可见,此处作者谈到了由自然灾害引起的损失所产生的结果,即政府和企业纷纷投资支持灾害预测的研究工作,这与答案选项的内容一致。
单选题 The difference between the actual loss caused by Hurricane Andrew and the loss estimated by insurance companies before the hurricane is
【正确答案】 C
【答案解析】解析:事实细节题。文章第二段第三句和第四句指出"例如,在1992年安德鲁飓风到来之前,许多保险专家认为可能到来的最强的飓风给保险业造成的损失也不会超过80亿。但是,估计安德鲁飓风造成的损失达到170亿,这粉碎了保险专家的观点"。从这部分我们能看到,保险公司预计损失是80亿美元,而实际的损失是170亿美元,两者之间的差额是90亿美元,故为本题正确答案。
单选题 The purpose of insurance companies to support disaster prediction research is that
【正确答案】 B
【答案解析】解析:事实细节题。文章第三段第三句指出"人们希望研究结果可以让保险业对未来的灾难风险做出决策时有更可靠的根据"。因此可以判断保险公司投资支持灾害预测研究的目的是为了能够利用预测信息对可能的灾害风险有更好的了解,并做出相应的决策。这与答案的内容一致。
单选题 The key factor to reduce society’s vulnerability to natural disasters is
【正确答案】 D
【答案解析】解析:事实细节题。文章末段第三句指出"飓风、龙卷风、水灾、地震、海啸、火山喷发都表明了灾害预测的有效使用不仅需要先进的技术,还需要社会考虑整个预测过程——预报、通讯和信息的使用"。可见,这里提及的正是增强社会对于自然灾害的抵御能力的关键,故为本题答案。
单选题 What can we infer from the last paragraph?
【正确答案】 C
【答案解析】解析:推理判断题。文章末段倒数第二句指出"因为还无法100%预测将来的事情,而需要了解的事情还很多,科学家警告说人类社会必须理解科学预测的局限性,并且做好有另一种选择的准备"。从句中的"人类社会需要了解的事情还很多"可以推测,人类未知的东西还很多,故可以推断出本题正确答案。
