Global Shortage of Fresh Water

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

【范文】

At present, many people take it for granted that fresh water will never be used up because we can find it not only from the rain, but also in the rivers, lakes and wells. Consequently, it is not necessary for us to worry about global shortage of fresh water.

In fact, the situation has become so serious that everyone should be aware of it and take immediate actions. With the world population increasing rapidly year after year, water resources are being consumed at an appalling speed. What's more, with the development of science and technology, modern industry needs much more water than before. Thirdly, pollution is also a worrying problem—water in rivers and wells becomes undrinkable because of industrial wastes.

We should take urgent measures to protect fresh water resources. The government should increase the efficiency of water usage by such methods as water recycling and purification of sea water. The people, on the other hand, should form the habit of cherishing every drop of water.  Last but not least, pollution must be effectively controlled, if we ever want to improve the quality of life.

【点评】
  本篇范文的最大特色是将批驳类与办法类结合,首段指出一些人的错误认识;第二段从三方面进行批驳;第三段指出我们的做法。
  范文首先指出,一些人认为淡水是取之不尽的,然后在第二段中进行批驳。首先,水资源正在被以惊人的速度消费。其次,现代工业需要更多的水资源。另外,因为工业污染,有些水已经不适宜饮用了。第三段阐述正确做法,即政府提高水资源的利用率、人人养成节约用水的习惯以及有效地控制水污染。    
  第一段第一句中的take it for granted表示“想当然”,be used up表示“用完,耗尽”。第三段第一点中的efficiency,recycling和purification分别指“效率”、“再循环”和“净化”。
