范文

The world is not only hungry, it is also thirsty. This may sound strange, since nearly seventy percent of the earth's surface is covered with water. But about ninety percent of this is sea water. Man and most of the animals can only drink and use the remaining percent of water—fresh water.

世界不仅饥饿，而且口渴。这听起来可能很奇怪，因为地球表面近70%被水覆盖。但其中约90%是海水。人类和大多数动物只能饮用和使用剩下的那部分水——淡水。

The need for water is increasing day by day. Only steps are taken to deal with this problem immediately can we avoid a severe world-wide water shortage later on. One of the first steps is to develop ways to reuse it.

对水的需求每天都在增加。只有立即采取措施解决这个问题，我们才能避免将来出现严重的全球性水资源短缺。第一步之一就是开发再利用水的方法。

Experiments have already been carried out in this field. The used water has been pumped to a water-purifying plant. There, it can be separated from waste matter and treated with chemicals so that it can be used again, just as if it were fresh water from a spring.

在这个领域已经进行了实验。用过的水被泵送到一个净水厂。在那里，它可以从废物中分离出来，并用化学物质处理，以便再次使用，就像它是来自泉水的淡水一样。
