文章大意：很多人都偏爱瓶装水。其实瓶装水有卫生安全、造成全球变暖危害以及产生固体废物垃圾等很多问题。
1.B 考查上下文逻辑关系。前面讲人们偏爱瓶装水，后面讲的是瓶装水的危害。所以表示前后转折的B项符合语境。
2.C 前面讲的是瓶装水大多数是用塑料装的，后面讲的是塑料制品生产过程中产生的危害。所以C项承上启下，符合语境。
3.E 空后讲的是瓶装水的储藏可能带来细菌的大量滋生。所以E项“健康问题源于不合适的储藏”符合语境。
4.G 此句作为瓶装水有安全问题的总结发言，因为下一段就是安全问题之外的缺点了。所以G项总结上文，与第一空照应。
5.F 空后讲的是瓶装水造成的固体垃圾污染问题。所以F项符合语境。
