2013年6月英语六级阅读理解Section A原文答案及点评Part IV Reading ComprehensionSection A原文+答案+点评Section ADirections: In this section, there is a short passage with 5 questions or incomplete statements. Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words. Please write your answers on Answer Sheet 2.Questions 47 to 51 are based on the following passage.Oil is the substance that lubricates the worlds economy. Because so many of our modern technologies and services depend on oil, nations, corporations, and institutions that control the trade in oil exercise extraordinary power. The “energy crisis” of 1973-1974 in the United States demonstrated how the price of oil can affect U.S. government policies and the energy-using habits of the nation.By 1973, domestic U.S. sources of oil. were peaking, and the nation was importing more of its oil, depending on a constant flow from abroad to keep cars on the road and machines running. In addition, at that time a greater percentage of homes and electrical plants were run on petroleum than today. Then, in 1973，the predominantly Arab nations of the Organization of Petroleum Exporting Countries (OPEC) resolved to stop selling oil to the United States. The move was prompted by OPECs desire to raise prices by restricting supply and by its opposition to U.S. support of Israel in the Arab-Israeli Yom Kippur War. The embargo (禁运) created panic in the West and caused oil prices to shoot up. Short-term oil shortages drove American consumers to wait in long lines at gas pumps.In response to the embargo, the U.S. government enforced a series of policies designed to reduce reliance on foreign oil. These included developing additional domestic sources (such as those on Alaskas North Slope), resuming extraction at sites that had been shut down because of cost inefficiency, capping the price that domestic producers could charge for oil, and beginning to import oil from a greater diversity of nations. The government also established a stockpile (贮存) of oil as a short-term buffer (缓冲) against future shortages. Stored underground in large salt caves in Louisiana, this stockpile is called the Strategic Petroleum Reserve, and currently contains over 600 million barrels of oil, roughly equivalent to one months supply.注意：此部分试题请在答题卡2上作答。47.
