阅读下面两则材料，完成1—3题。

【材料一】

 南水北调工程，是缓解我国北方水资源严重短缺局面的战略性基础设施，分东、中、西三条线路。东线、中线一期工程已分别于2013年和2014年通水，以南方充盈之水 ① （滋润  滋养）北方干渴大地的梦想已经实现。南水北调工程将发挥显著的社会效益、生态效益和经济效益。以中线一期工程为例，输送的距离长，流经的范围广，沿线经过多个大中城市，每年可输送的调水量达95亿立方米，相当于黄河水量的1/6，直接受益人口达6000万。根据需要，后期将进一步扩大调水规模，减少地下水开采，使水生态恶化的趋势得以缓解。随着受水区水资源生态的改善，影响北方经济发展的“瓶颈”将逐步消除，从而为这些地区经济结构调整创造机会和空间。

【材料二】

    2014年12月27日，北京市南水北调工程正式通水。南水北调工程年均为北京送水12.4亿立方米，供水范围达6000平方公里，成为北京的主力水源，城市供水保证率将由75%提高到95%。此外，南水北调工程通水后，不仅减少北京重要水源地密云水库的出水量，还可以将富余来水调入密云水库存蓄，大大加强北京水资源战略储备。南水北调工程通水后，北京将逐步关闭大部分自备井，通过天然和人工②  （回填  回补），有效遏制地下水位的大幅下降。同时，部分来水还可向首都的河湖补充清水，增强水体的稀释自净能力，改善河湖水质。
