以下是在线为同学们整理的英语难句解析，供各位考生参考。

　　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: PepsiCos Aquafina and Coca-Colas Dasani are both purified tap water rather than spring water.

　　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，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。
