(2020·惠州调研)By 2025, water shortage will be a big problem for about 1.8 billion people. In a world where water resource is increasingly short, nations cannot afford to waste it.__16__ After we use water in our homes and businesses, it is washed away, and takes many valuable resources with it.
Waste water is rich in carbon and nutrients.__17__ A number of nations and major cities have already built waste water treatment plants.They can effectively recover nutrients and bioenergy, and produce “new water” that can be reused.But more than 80% of all waste water still currently flows into natural ecosystems, polluting the environment and taking valuable nutrients and other recoverable materials with it.
__18__ This is still better than the situation in smaller cities.In Latin American countries, those living in small and medium-sized cities at most treat it in the form of septic tanks (化粪池) that lack regular and proper maintenance.
Imagine that outside one of these small cities lies a lovely piece of land: on the surface it is pleasingly built and provides habitats for local wildlife. Beneath the surface is a wetland that treats waste water and produces energy.The energy produced saves families from having to use firewood collected in the wild.This is not a dream project.__19__ A team of scientists have been looking into the potential of constructed wetland environments.Having analyzed 800 examples of biomass in more than 20 countries, they found that, depending on climate and the type of plant used in the construction of this type of wetland, up to 45 hectares of land could be irrigated with waste water.__20__
A．But that is exactly what we do.
B．This can provide easy access to clean water.
C．There is no longer any good reason to waste any type of water. D．A constructed wetland environment is already in practice on a small scale.
E．This would reduce the need for fresh water for irrigation and energy for pumping.
F．If collected and treated properly, it could provide “new water”， fertilizer, and energy.
G．Although waste water systems in large cities are effective, the whole procedure usually costs much.
语篇解读：本文是一篇说明文，主要介绍了当前世界水资源的现状以及有效利用水资源的方法。 16．解析：选A 上文说在水资源短缺的大环境下，很多国家不能承担浪费(的后果)，下文说我们用完水后，就直接把水冲走。根据上下文可知，A项“但是那正是我们所做的”与此处匹配，起承上启下作用，故选A。
17．解析：选F 上文说废水富含碳元素和养分，而F项说如果收集和处理得当，它就能提供“新的水”、肥料和能量，前后形成语义上的衔接，故选F。
18．解析：选G 下文讲述的是拉丁美洲的中小城市的废水处理系统缺乏常规和合适的维护，而G项提到大城市的废水处理系统有效但成本高，与本段内容吻合，故选G。
19．解析：选D 上文提到在这些小城市建造湿地环境的设想，下文提到已经有科学家在研究建造的湿地环境的潜力了，由此可知，D项“建造的湿地环境已经在小范围的实践中了”符合语境。
20．解析：选E 上文讲述的是这种解决方案的另一种好处是人们可以用废水灌溉农田，而E项说这可以减少用淡水灌溉的需求及抽水所需的能量，前后语义衔接，故选E。
