【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(jìn)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(yán)重缺水。

節(jié)約用水,合理用水,保護(hù)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(fèi)水資源。故選:C。
