【题目】A

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(短缺) water. Why? Because about 97% of water on the earth is sea water which we cant 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 cant even use all of that, because some of it has been polluted.

Now more water is needed. The problem is: Can we avoid a serious water shortage (短缺) later on?

First we should all learn how to save water. Secondly, we should find out the ways to reuse it. Scientists have always been making studies in the field. Today, in most large cities water is used only once and then runs to the sea or rivers. But it can be used again. Even if every large city reused its water, still there 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 get the salt out of the sea water. This is expensive, but its already used in many parts of the world. Scientists are trying to find a cheaper way of doing it. So you see, if we can find a way out, well be in no danger of drying up.
