BBC环球慢速英语 第244期:埃克森公司瓦尔德斯号油轮原油泄漏事故(5)

voice 1: The Exxon Company had to clean the spill. But they received help from the military and people who lived in the area. Many teams of people worked to clean the coast and the surviving animals. The teams used different methods to clean up the oil. In some areas they burned oil floating on the water. Other crews used machines to gather the oil. But the oil and plants in the water damaged the machines. Some crews used chemicals to break down the oil. But the waves were not large enough to mix the chemical with the oil.
声音1：埃克森公司必须清理泄漏石油。他们得到了军队和该地区民众的帮助。许多团队努力清理海岸并救助幸存的动物。这些团队在清理石油时使用了不同的方法。在其中一些地区，他们燃烧浮在水面上的石油。其他团队则用机器收集石油。但是，石油和水中的植物损坏了机器。还有一些团队用化学物质去分解石油。但是，海浪不够大，不足以将化学物质和石油混合在一起。

voice 2: Other teams used hot water at a high pressure to move the oil off the rocks back into the water. Workers would then collect the oil from the surface of the water. Some people even cleaned the oil-covered rocks by rubbing them with cloth. The oil travelled down the coast for more than a month. It took a very long time to clean the oil from the coast. Workers would clean an area, but then the ocean current would change. Oil would cover the clean areas again.
声音2：其他团队用高压热水去除水中岩石上的石油。然后工作人员会收集水面上的石油。有些人甚至通过用布擦拭的方法来清理岩石上的石油。石油在海岸扩散了一个多月的时间。清理海岸上的石油花费了很长时间。工作人员要先清理一个地区，可是洋流会变化。石油会再次覆盖干净的地区。
