What were the scientists worried about soon after the Gulf War?
When Iraqi troops blew up hundreds of Kuwaiti oil well at the end of Gulf War, scientists feared environmental disaster. Would black powder in 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. It has formed huge lakes in the Kuwaiti desert. They trap insects and birds, and poison a variety of other desert animals and plants.
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.
Officials are trying to organize a quick cleanup, but they are not sure how to do it. One possibility is to burn the oil. Get those black-powder detectors ready.
选项
A、The threat of poisonous desert animals and plants.
B、The exhaustion of energy resources.
C、The destruction of oil wells.
D、The spread of the black powder from the fires.
答案
D
解析
题干问:“海湾战争后不久,科学家们最担心的是什么?”听力材料的开始说“…scientists feared environmental disaster.Would black powder in the smoke from the fires circles the globe and block out the sun?”所以答案D“来自大火中黑色粉末的扩散”符合题意。
