八、阅读回答问题

The world is not only hungry, but 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 this huge amount is sea water, or salt water. Man can only drink and use the other 3%—the fresh water that comes from rivers, lakes, underground and other sources (来源), and we cannot even use all of that. Even worse, some of it has been polluted.

However, as things stand today(以目前的情况来看), this small amount of fresh water is still enough for us. But our need for water is increasing quickly—almost day by day. We should take steps to deal with this problem now and in this way we can get away from a serious world—wide water shortage (短缺) later on.

We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Today in most large cities, water is used only once and then sent out into a sewer (污水管) system. From there it returns to 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’d have to do to make use of sea water in the world is to take away the salt. If we take these steps, we'll be in no danger of drying up.

49．Where does the fresh water come from?

______________________________________________________________

50．Is our need for water becoming larger and larger or smaller and smaller?

______________________________________________________________

51．Our world isn’t thirsty for water, is it?

______________________________________________________________

52．Why should we take steps to deal with this problem?

______________________________________________________________

53．What happens to water in most large cities today?

______________________________________________________________

54．Can we stop wasting our precious water? Which step can we take to deal with the problem?

______________________________________________________________
