SWT一直都是PTE考试的重中之重，由于PTE的交叉打分机制，SWT一定程度上也决定着阅读分数的高低。但因为机经命中率比较高，考生往往忽略了练习的重要性，背一遍机经就去考试了。考试的时候如果纯靠回忆，很容易在高度紧张的时候忘记，而且一旦题目稍有变化将会不知所措，大大影响作文成绩。所以在备考阶段，对每篇SWT真题进行透彻的学习和分析，才是正确的复习方法。

Water is at the core of sustainable development. Water resources, and the range of services they provide, underpin poverty reduction, economic growth and environmental sustainability. From food and energy security to human and environmental health, water contributes to improvements in social well- being and inclusive growth, affecting the livelihoods of billions.
In a sustainable world that is achievable in the near future, water and related resources are managed in support of human well-being and ecosystem integrity in a robust economy. Sufficient and safe water is made available to meet every person’s basic needs, with healthy lifestyles and behaviours easily upheld through reliable and affordable water supply and sanitation services, in turn supported by equitably extended and efficiently managed infrastructure. Water resources management, infrastructure and service delivery are sustainably financed. Water is duly valued in all its forms, with wastewater treated as a resource that avails energy, nutrients and freshwater for reuse. Human settlements develop in harmony with the natural water cycle and the ecosystems that support it, with measures in place that reduce vulnerability and improve resilience to water-related disasters. Integrated approaches to water resources development, management and use − and to human rights − are the norm. Water is governed in a participatory way that draws on the full potential of women and men as professionals and citizens, guided by a number of able and knowledgeable organizations, within a just and transparent institutional framework.

手动分段之后我们会发现，从这里开始文章讲了一些非常具象的东西，但它们都在同一个整体范围内，即为如何让人人能够享受到affordable的water resources。
因此，水资源的管理，基础设施以及服务建设等等的相关的finance便十分重要了起来。
那么在治理废水这方面，我们也同样需要做到保持可循环、可持续发展这样的特性，以保证现在已经较为脆弱的生态系统能够正常的运转。
文章的最后，作者呼吁我们要保护整个水循环系统，并且提出了一个framework的概念。
读过文章之后我们大概可以分析出，文章遵循一个总分的机构。
开头先总得讲述了水的重要性及其作用，然后再分别描述了在各个方面我们应该保持可持续发展的重点性以及必要性：如在经济方面或者在循环再利用方面。
最后呢，作者号召大家，既然保护水资源这么重要，应该动用大家的知识和智慧来一起建立一个framework去保护水资源。
最后附上参考答案：
As the core of sustainable development,water should be managed appropriately to achieve improvements in socialwell-being both environmentally and economically; moreover, the financing ofwater resource management, infrastructure and service delivery are important aswater should be made affordable to every single person, with the protection ofa transparent institutional framework.
