Nevertheless, soft-drink companies view bottled water as the next battle-ground for market share-this despite the fact that over 25 percent of bottled water comes from tap water: PepsiCo‘s Aquafina and Coca-Cola‘s Dasani are both purified tap water rather than spring water. (06.12 Passage 1)

　　分析主干：companies view bottled water as the next battle-ground...

　　破折号后的this 指代前面的内容：view... share(把瓶装水看做下一个市场份额的竞争场所)，despite 是介词，后接宾语the fact，表示让步：“尽管事实上......”。that 引导的从句作the fact 的同位语。冒号后的内容是对同位语从句内容的进一步解释说明。

　　译文：尽管如此，软饮料公司把瓶装水看做是争夺市场占有率的下一个战场—虽然事实是超过25%的瓶装水都来自自来水：百事可乐的Aquafina 和可口可乐的Dasani都是经过净化的自来水，而不是矿泉水。
