     The world is not only hungry, but it is also thirsty for water. This may seem strange to you, since nearly
70% of the earth's surface is covered with water. But about 97% of that is sea water, or salt water. Man can
only drink and use the other 3%-fresh water from rivers, lakes, underground, and other sources (资源).
But we cannot even use all of that.
      However, our need for water is becoming larger almost day by day. We should take steps (措施) to deal
with (对付; 处理) this problem now and in this way we can avoid (避免) a serious worldwide water shortage
later on.
      We all have to learn how to stop wasting our valuable water. One of the first steps is to develop (开发;
发展) ways of reusing it. Today in most large cities, water is used only once and then sent out into a sewer
system (下水道). From there it returns to the sea or runs into underground places.
      But even if (即使) every large city reused its water, we still would not have enough.
     All we have to do, to make use of (利用) sea water in the world, is to remove (去除) the salt. But it is not
an easy thing.
