问题    Over the years, college students have stood together for what they believe in, from civil rights to anti-war policies to the more recent protests against the unequal distribution of wealth. But nowhere in history have students banned bottled water, until now.
   The bottled water ban, which started on just a few campuses, has now spread nationwide to more than 20 universities. The colleges have either completely banned the use of plastic bottles altogether, or some have taken a more limited approach with partial bans.
   Many people believe that producing and using bottled water wastes money and harms the environment. They say that bottled water is unnecessary because public water supplies in the U. S. are among the best in the world. Water fountains and reusable bottles with easy access to filling stations are a better choice.
   An organization called Ban the Bottle raises awareness about the economic and environmental costs of using plastic bottles. The group claims that eight glasses of water a day costs each person 49 cents annually, while drinking from plastic containers costs $ 1, 400 per year. Plastic bottles contain antimony—a chemical that in low doses causes depression, but in large doses can even lead to death.
   The controversy over bottled or tap is not limited to the students and college administrations. The makers of bottled water see the movement as a threat. They argue that plastic bottles make up a small portion of the nation’ s total waste. It’ s unfair to single out (单独挑出) their product when so many other items are packaged in plastic containers. Plus, water is a healthy choice compared to some sodas and juices that are also sold at school.
According to the passage, which of the following statements is TRUE ?

选项 A、All the universities have banned the sale of bottled water.
B、Plastic bottles may do harm to people’ s health.
C、The purchase of soft drinks will increase.
D、Bottled is cheap and environment-friendly.

答案B

解析 细节题。根据第二段可知,起初禁止瓶装水的运动只在少数大学进行,但很快就蔓延开来,如今已延伸到20所大学,故排除A;由第四段可知,塑料瓶含有一种名为“锑”的化学元素,小剂量可能会引起抑郁,大剂量会致命,故B选项正确;由第五段可知,与一些在学校出售的苏打水和果汁相比,水仍然是一种健康的选择,排除C;根据第三段可知,许多大学生认为生产和使用瓶装水会造成资金浪费和污染环境,故D错误。
