Directions: For this part, you are allowed 30 minutes to write a composition on the topic Global Shortage of Fresh Water. You should write at least 100 words and you should base your composition on the outline (given in Chinese) below:

1.人们以为淡水是取之不尽的(提示：雨水、河水、井水……);

2.实际上淡水是非常紧缺的(提示：人口增长、工业用水增加、污染……); 3.我们应该怎么办。

根据提纲要求，可以进行如下构思：

第一段应解释为什么人们认为淡水是取之不尽的。根据提示，我们可以从降雨丰富、河水和井水等水资源充足方面进行解释。

第二段应重点解释导致淡水紧缺的原因，这些原因主要有：人为的浪费、人口增加、工业用水增加、水资源被污染等等。

第三段是本文的重点。阐述如何解决淡水紧缺问题时，切忌只简单地写出“We should take measures to solve the problem.”这样空洞的、表态性的句子，而不提出具体的解决方法。只有提出具体的解决方法，才能使文章显得充实，有说服力。

根据上面的构思，可以列出下列提纲： Topic: Global Shortage of Fresh Water

Question: What has caused the global shortage of fresh water and how can we solve the problem? Outline:

I. It is widely assumed that fresh water is inexhaustible. 1. Plenty of rainfall 2. Numerous wells

3. Countless rivers, falls and springs

II. There are three causes for a global shortage of fresh water. 1. Population growth

2. Development of industry & agriculture 3. Water pollution

III. Measures should be taken to solve the problem. 1. Protect water resources from being polluted 2. Save water

3. Recycle water & convert sea water into drinkable water. 范文：

At present,many people take it for granted that fresh water is inexhaustible because it can found not only from the rain,but also in the rivers,lakes and wells.Consequently,it is not necessary to worry about global shortage of fresh water .However,the fact is that such a belief is unfortunately wrong and possibly dangerous.

Despite the fact that seventy percent of the earth’s surface is covered with water,only a little part of it is fresh.Yet the demand for fresh water in our daily life and in industry increases sharply as the results of the expansion of the population and the development of industry .It is estimated that if such trend continues,the fresh water on earth will be used up very soon.What is

worse ,more and more water resources are being polluted,making the water unfit to use.

To improve the severe situation,immediate actions should be taken to protect fresh water resources.The government should promote the awareness of the conservation of water resources so that everyone consciously economizes on water.Moreover,laws should be made to control the wastes produced by factories so as to ensure that water is not further polluted.Furthermore,the efficiency of water usage must be increased by such methods as water recycling and purification of sea water .In short,the global shortage of fresh water can be solved if effective measures are taken right away.
