word="C">C</span> <span word="A">A</span>和<span word="D">D</span>明显不是正确答案。<span word="B">B</span>不是正确选择，因为只有当这种新的燃料电池被大规模生产时，才有可能实现用甜饮料给手机提供电能。 2. <span word="C">C</span> 该段第二句<span

word="glucose">glucose</span>，而不是<span word="a">a</span> <span word="sugary">sugary</span> <span word="liquid">liquid</span>，因 此<span word="C">C</span>是正确选择。 3. <span word="D">D</span> 文章的最后一段指出了这种新型燃料电池的优点，即<span word="A">A</span>、<span word="B">B</span>、<span word="C">C</span>所述内容。最后一句说，科学家预计，在不到三年的时间里这种新技术便可在大众的流行产品中使用。所以<span word="D">D</span>是正确选择。</p>
