APer capital water usage has been on an upward trend for many years 多年以來，人均用水量呈現上升趨勢。(per capital usage 人均用量，has been on an upward trend 上升趨勢，這兩個說法可以很好地用在小作文關于水資源用量的句子里，還有大作文報告類問題類論述背景或者問題里). As countries industrialize and their citizens become more prosperous, their individual water usage increases rapidly. 由于國家工業化發展和居民生活更加富裕，個人用水量快速增加(prosperous 繁榮興旺的，詞根是prosper vi/vt.使…昌盛，同義詞有 well-off ,thriving )

　　In the 21st century, the world’s limited supply of renewable fresh water is having to meet demands of both larger total population and increased per capital consumption. 21世紀，世界可再生淡水資源的限制供應就是為了滿足更多人口數量和日益增長的人均消耗需要。(renewable 可再生的，renewable energy sources 可再生能源，能源話題高頻詞匯;fresh water 是淡水資源不是新鮮的水，salt water 指海水或咸水;meet demand of 滿足需要，consumption 消耗，energy consumption, power consumption 高頻用詞). The only practicable ways to resolve this problem in the longer term are economic pricing in conjunction with conservation measures. 從長遠來看，唯一切實可行的解決方法是上調用水價格連同保護措施。(the +adj way to do sth在大作文報告類里說明解決方法是一個很好的句型，practicable 切實可行的，近義詞 feasible, workable ; in the longer term 從長遠來看，長期內; in conjunction with 結合，與…協力;conservation 對自然資源的保護或保持，近義詞 preservation , 動詞形式也比較好用)。

　　BAgriculture consumes about 70% of the world’s fresh water，so improvements in irrigation can make the greatest impact. 農業用水消耗全世界淡水資源的70%，因此灌溉改善將能夠產生最重大的影響。(make the great impact on 對…有重大的影響)。Simple changes could improve the rate substantially, though it is unrealistic to expect very high levels of water-use efficiency in many developing countries, faced as they are with a chronic lack of capital and a largely untrained rural workforce. 雖然期望發展中國家有很高水平的水資源利用率是非常不現實的，因為這些國家長期面臨資金短缺和大量未經培訓的農村勞動力問題，但是簡單的改變都能夠很大程度上改善用水比率。(substantially 很大程度上，從實質上;chronic 長期的，慢性的;a lack of 缺乏，缺少;workforce 勞動力;長句子練成法之一，多使用從句和分詞結構)。Paper production too is often very water-intensive. 造紙產業也是一個耗水產業。(water-intensive 水密集型的/耗水量大的，intensive 加強的，集中的，例如intensive training, 反義詞extensive 粗放的，extensive management ).

　　CIn rich countries, water consumption has gradually been slowed down by price increases and the use of modern technology and recycling. 發達國家已經通過使用調升價格和當代科技與循環逐步減少了水資源消耗( gradually 逐步地，slow down 減慢，減少)。However, industrial water consumption is continuing to increase sharply in developing countries. With domestic and agricultural demands also increasing the capacity of water supply systems is under growing strain. 然而，在發展中國家，工業耗水量正在持續快速增加。同樣地，家庭和農業用水需求量也給水供應系統帶來日益緊張的壓力。(capacity 容量，產量;be under growing strain 面臨越來越大的壓力，使日益緊張，報告類作文描述問題嚴重性非常好用)

　　以上三段分析了水資源使用現狀和主要問題，和大家分享了關于環境資源類話題的部分高級詞匯短語，希望可以為你所用，豐富知識。下次將會為大家繼續關注水危機最佳解決方案，耐心等待哦。順便說一下，水危機是全球性的，而且我們大中華水危機現象特別嚴重，因此Mina呼吁各位同學跟上全球腳步，從身邊做起，關注水危機。
