【題目】關(guān)于節(jié)約用水的敘述，不正確的是（）

A.推廣噴灌、滴管技術(shù)B.工業(yè)用水重復(fù)使用，循環(huán)使用

C.利用流水解凍食物D.生活用水一水多用

【答案】C

【解析】

中國水資源的狀況不容樂觀。水資源的時空分布也不夠理想，加之一部分水資源受到污染和破壞，能夠有效利用的水資源就更少。有些地區(qū)因地下水過度開采，造成地下水位下降，進而加劇了用水的困難程度。中國大部分城市存在著供水不足的問題，有100多個城市嚴重缺水。

節(jié)約用水，合理用水，保護水資源，防治水污染，提高水資源的利用效率，是緩解缺水問題的有效途徑。比如，在農(nóng)業(yè)生產(chǎn)中更多地采用滴灌等節(jié)水灌溉模式，工業(yè)用水重復(fù)使用，循環(huán)使用，生活用水一水多用等等；ABD正確；C錯誤，用水解凍食物，會浪費水資源。故選：C。
