The world is not hungry, but it is thirsty. It seems strange that nearly 3/4 of the earth is covered with water while we say we are short of water. Why? Because about 97% of water on the earth is sea water which we can't drink or use for watering plants directly. Man can only drink and use the 3%-the water that comes from rivers and lakes. And we can't even use all of that, because some of it has been polluted.
Now more water is needed. The problem is: can we avoid(避免) a serious water shortage later on? First, we should all learn how to save water. Secondly, we should find out ways to reuse it. Today, in most large cities water is used only once and then runs to the sea or rivers. But it can be used again. However, even if every large city reused its water, there still would not be enough. What could people turn to next?
The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to remove the salt from the s

这个世界并不饿,但它是很渴。很奇怪,近四分之三的地球被水覆盖着当我们说我们所缺少的是水。为什么?因为97%的水对地球的海水,我们不能喝或使用浇水。人只能喝的水,用3%-the来自于河流和湖泊。我们甚至不能使用所有这一切,因为其中一些已经被污染了。
现在需要更多的水。问题是:我们可以避免(避免)严重缺水后来呢?首先,我们都应该学习如何节约用水。其次,我们必须找出方法来的重用。今天,在大多数大城市的水是仅使用一次,然后跑去海边或河流。但它可重复使用。然而,即使每个大城市都使用再生水,但仍然还是不够的。什么人转向了吗?
海似乎有最好的答案。有许多水在海里。所有需要做的一切就是移去盐海水的。这是昂贵的,但是它已经发生在世界上许多地方。科学家们正试图找到一个便宜的方式消除它。所以你看,如果我们能找到出路,我们将在没有危险。
