2017-2018学年高中英语Module4SandstormsinAsiaSectionⅠIntroduction&ReadingPre-reading外研必修3_图文

In April 2012, a dust storm that originated in China and Mongolia took a six-day journey across more than ten thousand kilometers of sea and open land to Arizona in the United States. The cloud was so dense that it seemed as if the sun were setting early. At least one person thought a volcano had erupted.
Although traveling dust storms are nothing new, the dust now often contains chemical or metallic substances that contribute to respiratory illnesses (呼吸道疾病) and damage the environment. At present, a group of researchers in Asia is studying aerosol particles and their effects on the environment — and they have plenty of dust to work with.

Dust storms are one of the repercussions (后果) of humans messing around with Mother Nature. Although they are a natural phenomenon, dust storms have been occurring more often, at shorter intervals, and with greater force in recent years, and human activity is the cause.
It is a fact that excessive herding of animals and exploitation of grasslands are responsible for the majority of dust storms. This means that dust storms are largely a result of human actions; in other words, they are controllable.

亚洲的沙尘暴 [第 1~2 段译文]
几百年以来,沙尘暴一直是许多亚洲国家面临的一个主要灾 难。科学家们已尝试过许多方法解决这个问题,在中国,一场大 规模的帮助解决沙尘暴问题的运动已经开始了。

沙尘暴是夹带沙尘的强烈而干燥的风。沙尘暴常常很浓密, 以至于遮住了太阳,有时风力大的足以移动沙丘。世界上沙尘暴 发生的四个主要地区是中亚、北美、中非和澳大利亚。来自内蒙 古的任建波是这样来描述他小时候在沙漠中遭遇的一次可怕的 沙尘暴的:“遭遇沙尘暴是一种可怕的经历。”他说:“你一点儿 办法也没有。那是我遭遇过的最可怕、最危险的境况。你只能希 望自己会活下来。那时候我以为我要被沙子淹没了。”
