答案與題解：
1． C A和D明顯不是正確答案。B不是正確選擇，因為只有當這種新的燃料電池被大規(guī)模生產(chǎn)時，才有可能實現(xiàn)用甜飲料給手機提供電能。
2． A 文章第三段的第一句是問題的答案。
3． C 該段第二句“When glucose from a sugary liquid penetrates a pocket，the enzyme oxidizes it，releasing electrons and proton”中的it指代glucose，而不是a sugary liquid，因 此C是正確選擇。
4． B 第六段的大意是，盡管這種新型燃料電池還不能產(chǎn)牛很多電能，但是，它能夠產(chǎn)生電能的事實就已經(jīng)是很大的成就了。因而激動人心。所以只有B是正確答案。
5． D 文章的最后一段指出了這種新型燃料電池的優(yōu)點，即A、B、C所述內(nèi)容。最后一句說，科學家預計，在不到三年的時間里這種新技術便可在大眾的流行產(chǎn)品中使用。所以D是正確選擇。
