大学英语四级听力专题练习听力真题：Passage Three33.A. The threat of poisonous desert animals andplants.B. The exhaustion of energy resources.C. The destruction of oil wells.D. The spread of the black powder from the fires.34.A. The underground oil resources have not been affected.B. Most of the desert animals and plants have managed to survive.C. The oil lakes soon dried up and stopped evaporating.D. The underground water resources have not been polluted.35.A. To restore the normal production of the oil wells.B. To estimate the losses caused by the fires.C. To remove the oil left in the desert.D. To use the oil left in the oil lakes.答案解析：Passage ThreeWhen Iraqi troops blew up hundreds of Kuwaiti oil wells at the end of the Gulf War, scientists feared an environmental disaster. [33]Would black powder and the smoke from the fires circle the globe and block out the sun? Many said No way. Rain would wash the black powder from the atmosphere. But in America, air-sampling balloons have detected high concentrations of particles similar to those collected in Kuwait. Now that the fires are out, scientists are turning attention to yet another threat-the oil did not catch fire. It has formed huge lakes in the Kuwaiti deserts. They trap insects and birds and poison a variety of other desert animals and plants. [34]The only good news is that the oil lakes have not affected the underground water resources. So far, the oil has not been absorbed because of the hard sand just below the surface.Nothing, however, stops the oil from evaporating. The resulting poisonous gases are choking nearby residents. [35]Officials are trying to organize a quick clean-up, but they are not sure how to do it. One possibility is to burn the oil. Get those black powder detectors ready.Questions 33 to 35 are based on the passage you have just heard.33. What were the scientists worried about soon after the Gulf War?正确答案：D解析：题目询问海湾战争结束之后不久，科学家们担心什么。
