问题     Preserving Water Sources
    Recently we held a successful daylong workshop that was attended by local primary and secondary school teachers as well as several university students representing the environmental groups on their campuses. The workshop was unique: To convey how critical water is to the survival of society, we showed to what an extent our bodies are water and how the natural environment also revolves around it. We depicted the intimate connection between the functions of the human body and water, and further showed how human systems have parallels in nature. Our participants were amazed that, when shown on the same scale, the human cardiovascular system of veins and arteries and an aerial view of a river system were so much alike as to be indistinguishable. We also showed them the similarities between a human bone and a tree. Nerves, when a person experiences pleasure, look relaxed and have many curves, like a healthy river that also has numerous bends and curves. We contrasted these with a picture of a nerve straight and stiff as it feels pain; alongside it we placed a picture of a river that has been manipulated by human engineering and rendered straight, unhealthy and lifeless.
    Once our participants had gained a new appreciation for water, the urgent need to protect this precious resource became plain to them. We followed up by spending some time thinking about concrete projects that they could undertake with their students or green groups.
    Many great project ideas were voiced that day and some are already getting underway. A secondary school in Tianjin is beginning a campus greening project and wants to include greywater treatment as well as rainwater collection in their plan. Students from a local university are campaigning to reduce the water usage in their bathhouses. Currently, students pay one price for a shower of unlimited length, which invariably leads to waste. Their approach to cutting waste includes changing the pricing scheme and replacing the showerheads in their bathhouses with a water-saving type.

答案 保护水资源 最近,我们成功地举办了为期一天的研讨会。参加者是当地的中小学老师,还有一些大学生,他们代表自己大学的环保小组。研讨会别具一格:为了说明水对社会延续有多么重要,我们演示了人体内水占多少比例,自然界又如何离不开水。我们描述了人体各项功能与水的密切关系,并进一步演示了人体各系统如何与自然界相类似。当把人体静脉和动脉组成的心血管系统与河流体系的航空鸟瞰图以同一比例尺寸相比时,二者相似之极,简直难以区分,这使与会者大为惊奇。我们还向他们展示了人的骨骼与一棵树的相似之处。而神经呢,当一个人愉快时,就松弛下来,有许多曲线,就像一条正常的河流有许多弯弯曲曲一样。与此对照的一幅画是,神经在受痛苦时变得僵直;而旁边放着一张河流的照片,该河流由于人类工程改道而变得笔直、反常、死气沉沉。 与会者一旦对水有了新的了解,那么保护这一珍贵资源乃当务之急也就不言而喻了。接着,我们又花了一些时间探讨与会者同自己的学生或绿色组织能够承担的具体项目。 那天会上提出了许多很好的项目创意,有的已在进行之中。天津一中学已启动一项绿化校园计划;他们打算把污水处理与雨水收集包括在计划内。当地一所大学的学生们正发起一场在浴室中减少用水的宣传活动。目前,学生们付一次费可以洗多长时间不受限制,这难免引起浪费。他们制止浪费的方法包括改变收费办法,并给浴室换上节水型喷头。
