　　A new study warns that about thirty percent of the world's people may not have enough water by the year 2025.

　　A private American organization called Population Action International did the new study. It says more than three－hundred－thirty－five－million people lack enough water now. The people live in twenty－eight countries. Most of the countries are in Africa or the Middle East.

　　P－A－I researcher Robert Engelman says by the year 2025, about three－thousand－million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on Earth stays the same.

　　Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.

　　The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking waters not safe. Mr. Engelman says there are problems all over the world because of diseases, such as cholera, which are carried in water. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning.

　　The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.

　　The report also says long－term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.

1．According to the author's opinion, the first serious problem caused by lack of water is ________.

[　　]

4．Which of the following is not the way to solve the water problem?

[　　]

A．To control population growth.

B．To teach people not to waste water.

C．To find ways to use water for only one purpose.

D．To use less water of agriculture.

5．Which of the following is the main idea of the passage?

[　　]

A．How to get more water in the future.

B．Problems caused by water.

C．World water shortage.

D．A new study on water.

　　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.

[　　]

A．to deal with water problem now

B．to have lectures on the water subject

C．to develop ways of reusing water
