水资源短缺的原因是什么?并且提出一些方案来解决这个问题。
Since the beginning of time, water has been shaping the face of the earth. Water sustains human life,our environment and our cultures. But the global demand for water is increasing and the destruction of water-dependent ecosystems has accelerated.
From my point of view, the main reason of scarcity of water resource is the rapid population growth,especially in developing countries. In order to meet the great demand for water, people exploit water resource in various ways. Water supply sources are being stretched to their limits. And surface and groundwater pollution is increasing rapidly. Research indicates that over 1 billion people still do not have access to safe water supplies and over 1.7 billion do not have access to adequate sanitation facilities.
Another reason is the development of industry and agriculture. In some developing countries, some private factories make use of water resource low-efficiently and make much pollution. Irrigated agriculture also contributes to water scarcity. Despite the high yield, irrigation is extremely water intensive. It takes about 1,000 tons of water to grow one ton of grain and 2,000 tons to grow one ton of rice.
Finding solutions of the problem involves the increase of worldwide awareness and international cooperation. Every individual should realize water crisis and save water. As to the government, some effective measures should be taken, including erecting modern irrigation systems and increasing the number of sewage water recycling plants. Building more dams can also be an effective solution. Dams play an important role in detaining the surface rain water flowing from the mountains and would prevent the loss of rainwater straight into the sea.

资深老师解析：解释型题目，使用的是一边倒的结构。
有史以来，水一直在塑造着地球的表面。水支撑着人类的生命、我们的环境和我们的文化。但是全球水资源的需求量在不断增长，对依赖水资源的生态系统的破坏不断加剧。
在我看来，水资源缺乏的主要原因是人口的迅速增长，尤其是在发展中国家。为了满足对水的大量需求，人们以各种方式开采水资源。水源将近枯竭。同时，地表水和地下水的污染在加剧。研究表明，超过10亿人仍然未能使用上安全的供水系统，超过17亿人没有足够的卫生设施。
另一个原因就是工农业的迅速发展。在一些发展中国家，一些私人工厂低效率地使用水资源并且产生了大量的污染。农业灌溉也导致水资源的缺乏。尽管灌溉可以高产，但它要用很多水。种植一吨的谷物大约需要1 000吨的水，种植一吨的稻米大约需要2 000吨的水。
寻找解决这个问题的办法需要全世界人对这个问题的关注和国际合作。每个人都应该意识到水资源的紧缺并节约用水。至于政府，则应采取一些有效的措施，包括建立现代灌溉体系，增加污水循环利用的工厂。建造更多的大坝也是一个有效的解决办法。大坝在截流从山脉流下的地表水方面起着重要作用，它将防止雨水直接流到海里造成流失。

Sample Answer：
Water, a natural resource, has become a much sought-after economic good the management of which is likely to become a major global problem. Increasingly, there is an imbalance between the geographical and seasonal demand for and availability of water. This imbalance leads to over-use and exhaustion of reserves, even conflicts between competing users-if not between States. Even where water is in abundant supply, it is the subject of pollution and waste.
Pollution from industrial, agricultural and domestic sources has constantly reduced water quality in the world. In spite of a reduction in the use of pro ticides and fertilizers in agriculture, they are still present in the same concentrations in groundwater because of the often very long lime taken by pollutants to infiltrate into groundwater.
Waste water from industrial or urban sources also contributes to significant damages and serious environmental imbalances. In spite of a number of Directives which have led to a reduction in such pollution, their level is still too high in many areas.
The crucial challenge is the sustainable management of water resources, requiring a major scientific and technological effort which could not he achieved without international and multidisciplinary cooperation between researchers. To overcome these problems, Crossborder researches could cover the following: development of more efficient methods of irrigation in farming; the recycling of water and its substitution as a refrigerant, solvent or precipitation medium in various industrial sectors and the improved methods and technologies for water treatment and the restoration of polluted sites as well.

1.Fresh water has always been a limited resource in some parts of the world. Today, however, growing worldwide demand has made this a global problem.
What are the causes of the increased demand and what measure could governments and individuals take to respond to this problem?
2.Water is a natural resource that should always be free. Governments should ban the sale of bottled water.
To what extent do yoagree or disagree?
