问题 The phrase "the world" in the first line of the passage refers to
According to the passage, we can avoid a worldwide water shortage in the future by

选项 A、increasing rainfall
B、reusing water and utilizing sea-water
C、cutting down our consumption of water
D、reducing the number of factories producing steel

答案B

解析 问题问“为了避免在将来出现世界性的缺水,我们能怎样做?”利用问题句中的核心词“shortage”作为答案线索词,这样在第2段第2句中找到答案相关句,但该句没有直接回答问题,于是继续看该句的下文,这样在第3段的第一句中找到答案直接相关句:Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on.A limited water supply would have a bad effect on agriculture and industry.In addition to stopping wasting our precious water,one useful step we should take is to develop ways of reusing it.该划线句说“除了停止浪费珍贵的水资源以外,我们还应该采取的一个有效的方法是研制出水的再次利用方法”,因此确认答案为B(水的重新使用)。
