Question

阅读下面短文，将文中画线句子翻译成中文或英文。

        The world is not only hungry,but it is also thirsty for water. This may seem strange to you.

        31. As we all know,nearly 70  percent of the earth's surface is covered with water. But about 97  percent of this huge amount is sea water,or salt water. Man can only drink and use the other 3 percent. And we cannot even use all of that,because some of it is in the form of icebergs (冰川) .32. What's worse,some of the fresh water has been polluted.

Human beings should realize how serious the problem is. 33. 至少，我们得停止浪费水了。Of course,we ought to think about various ways to reuse our water. 34. 如今在大多数大城市里，水只会被用一次。

        Then it is sent out into a sewer system (下水道）From there it returns to the sea or runs into underground storage tanks. But it is possible to pipe used water to a purifying (净化) factory. There it can be treated with chemicals so that it can be used again.

        But even if every large city purified and reused its water,we still would not have enough. 35.Probably we ought to make use of the sea water on the earth. We can remove the salt to get fresh water. If we take these steps,we may be in no danger of drying up.
