问题     下面你将听到一段有关“废水利用”的内容。//
    As freshwater becomes increasingly scarce due to population growth, urbanization, the use of wastewater in agriculture, aquaculture and in other areas will increase.  //
    In some cases, wastewater is the only water resource available to poor, subsistence-level farming communities. Although there are benefits to using wastewater in agriculture uncontrolled use of wastewater frequently is associated with significant negative human health impacts. These health impacts can be minimized when good management practices are implemented. // Guidelines for the safe use of wastewater in agriculture need to find the right balance between maximizing public health benefits and still allowing for the beneficial use of scarce resources. Guidelines need to be adaptable to the local social, economic and environmental conditions and should be co-implemented with other health interventions such as provision of adequate drinking water and sanitation.  //

选项

答案   人口增长和城市化进程使得淡水变得日益匮乏,因此,在农业、水产以及其他领域使用废水的做法将会增多。
    在一些情况下,废水则是贫穷、只有最低生活水平的农业性社会唯一可用的水资源。虽然农业使用废水具备好处,然而未加控制的利用废水常常和造成严重负面性的健康问题有关。如果实施良好的管理措施,这些对健康造成的影响可以减到最小。在制定关于农业安全使用废水的条例时,需要找到公共卫生最大受惠和仍旧允许合理使用稀有资源之间的正确平衡点。指导方针需要适应当地的社会,经济以及环境的情况而且应当与其他卫生干预措施一起实施,例如提供充足的饮用水和卫生设施。
