　　文章大意：很多人都偏愛瓶裝水。其實(shí)瓶裝水有衛(wèi)生安全、造成全球變暖危害以及產(chǎn)生固體廢物垃圾等很多問題。

　　1.B　考查上下文邏輯關(guān)系。前面講人們偏愛瓶裝水，后面講的是瓶裝水的危害。所以表示前后轉(zhuǎn)折的B項(xiàng)符合語境。

　　2.C　前面講的是瓶裝水大多數(shù)是用塑料裝的，后面講的是塑料制品生產(chǎn)過程中產(chǎn)生的危害。所以C項(xiàng)承上啟下，符合語境。

　　3.E　空后講的是瓶裝水的儲(chǔ)藏可能帶來細(xì)菌的大量滋生。所以E項(xiàng)“健康問題源于不合適的儲(chǔ)藏”符合語境。

　　4.G　此句作為瓶裝水有安全問題的總結(jié)發(fā)言，因?yàn)橄乱欢尉褪前踩珕栴}之外的缺點(diǎn)了。所以G項(xiàng)總結(jié)上文，與第一空照應(yīng)。
