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.

漓江是数千年来无数文人志士获得灵感的地方。两岸是连绵的山峰，平静的河水倒映出魔幻般的美景，宛如童话一般。山峰在薄雾笼罩下时隐时现，令人陶醉。泛舟漓江，每个转弯处都能找到新奇，或见懒洋洋的水牛拉着大车，或见渔民在狭窄的竹筏上悠然自得。

解决13亿人的问题，不能靠别人，只能靠自己。中华人民共和国成立以来，我们的建设取得了很大成就，同时也走了一些弯路，失去了一些机遇。从1978年开始改革开放，我们终于找到了一条发展自己的正确道路。这就是：中国人民独立自主地建设中国特色的社会主义。 这条道路的精髓，就是调动一切积极因素，解放和发展生产力，尊重和保障中国人民追求幸福的自由。中国的改革开放，从农村到城市，从经济领域到政治、文化、社会领域。它的每一步深入，说到底，都是为了放手让一切劳动、知识、技术、管理和资本的活力竞相进发，让一切创造社会财富的源泉充分涌流。

In bringing up children, every parent watches eagerly the child's acquisition(学会)of each new skill—the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself. Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are severe over times of coming home at night or punctuality for meals. In general, the controls imposed represent the needs of the parents and the values of the community as much as the child's own happiness. As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality(道德). Also, parents should realize that "example is better than precept". If they are not sincere and do not practice what they preach(说教), their children may grow confused, and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled. A sudden awareness of a marked difference between their parents' principles and their morals can be a dangerous disappointment.
