A Thirsty World
Three-fourths of the earth’s surface is covered by water, some of which is frozen and most of which is salty. In fact, less than one percent left for all the living things.
Now fresh water is becoming scare, but more and more is needed because of the increasing number of people. Some industries also use amounts of fresh water in the production of things such as steel, paper, and rubber. These factories have polluted water flow into rivers without making it clean. What’s more, people in the city have much dirtied water piped into ditches after cooking every day.
Scientists estimate that the need for fresh water will have doubled by the year 2003. This means that we must find new ways of saving it or producing it. Some nations have worked on the problem and are already sharing their information with others. They are trying to keep their rivers from being polluted. Deep wells are also being dug, and rainwater is being collected in huge artificial lakes. In one way or another, they hope to provide enough water to satisfy the needs of their people. For example, one important wayof producing water is to distill(用蒸馏法提取) it from sea water. After the salt has been removed, sea water can be used not only for drinking but also for industry and irrigation. However, the equipment for distillation process is very expensive. Distilled water might be as dear as gold if pollution goes on.

The world is not only hungry, it is also thirsty for water. This may seemstrange to you, since nearly 75％of the earth's surface is covered with water. But about 97％ of this huge amount is seawater, or salt water. Man can only drink and use the other 3％--the fresh water that comes from rivers, lakes, underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.
However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall is still enough for us. But our need for water is increasing rapidly almost everyday. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small example of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91000 litres of water?
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. Experiments have already been done in this field, but only on small scale. The systems that have been worked out are similar to those used in spacecraft.
(1) “The world...is also thirsty for water.” this means that ________.
[ ]
A．the world has not enough fresh water to meet our future needs
B．people all over the world are thirsty for water now
C．we are now facing a serious problem of world-wide water shortage
D．we cannot make use of all the fresh water on earth
(2) According to the passage, only about ________ of the earth's surface is covered with fresh water that can be used.
[ ]
(3) We may face a severe worldwide water shortage in the future because ________.
[ ]
A．the small amount of fresh water is constantly being replaced by rainfall
B．some of it has been polluted
C．some of it is in the form of icebergs and glaciers
D．our need for fresh water is increasing rapidly
(4) According to the passage, one of the first problems is ________.
[ ]
A．to deal with water problem now
B．to have lectures on the water subject
C．to develop ways of reusing water
D．to work out systems that resemble those used in spacecraft
(5) This passage is mainly about ________.
[ ]
The world is not only hungry, but it is also thirsty for water．This may seem strange to you，since 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-the fresh water from rivers，lakes，underground，and other sources．And we cannot even use all of that，because some of it is in the form of icebergs and glacier．Even worse，some of it has been polluted．
However，as things stand today, this small amount of fresh water is still enough for us．But our need for water is increasing rapidly-almost day by day．Only if we take steps to deal with this problem now can we avoid a severe 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 ways of reusing it．
Today in most large cities，water is used only once and then sent out into a sewer system．From there it returns to the sea or runs into underground storage tanks．But it is possible to pipe used water to a purifying plant．There it can be treated with chemicals so that it can be used again，just as if it were fresh from a spring．
But even if every large city purified and reused its water，we still would not have enough．All we'd have to do make use of the vast reserves of sea water in the world is to remove the salt．
If we take these steps we'll be in no danger of drying up．
56．The world is thirsty for water because we can only use percent of the water covering the surface of the earth．
A．3 B．more than 3 C．less than 3 D．97
57．Which of the following statements is NOT TRUE?
A．As things remain unchanging，this small amount of fresh water is still enough for us．
B．Our need for water is becoming larger and larger．
C．There will be no water shortage in the future．
D．We should take steps to deal with the water shortage problem．
58．To reuse water, we should ．
A．treat it with chemicals B．use it only once
C．send it out into a sewer system D．make it flow into underground tanks
59．In order to have enough water．we should also make use of ．
A．icebergs and glaciers B．sea water
C．rivers and lakes D．underground water
