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 are 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.

           are expected to have severe water problems by the year 2025.

A. 18 countries                             B. No countries

    C. 46 countries                            D. 28 countries

All the following are true except            .

    A. New industries need a lot of water

    B. There are solutions to the water problem

    C. Egypt now has enough fresh water

    D. Lack of water may cause conflict between countries

It can be learned that           .

  A. The ability of developing has nothing to do with lack of water.

    B. . It is not known whether diseases have something to do with lack of water

    C. Lack of water may also result from international conflict

    D There is connection between providing clean water and slowing population growth

The best title of the passage would be          .

  A. World Water Shortage                       B. Population and Water

    C. World Conflict                           D. Diseases and Water

A lady and her husband stepped off the train in Boston. They walked without an appointment（预约）into the outer  31_ of Harvard’s president(哈佛大学校长). But they were  32  by his secretary and kept waiting. For hours, the secretary took no notice of them,  33  that the couple would finally become  34  and go away. But they didn’t. The secretary finally decided to disturb the president, though  35  .

A few minutes later, the president walked towards the couple with a  36  face. The lady told him, “We had a son that  37_ Harvard for one year. He loved Harvard. He was  38  here. But about a year ago, he was accidentally killed. My husband and I would like to  39  a memorial（纪念物）to him, somewhere on campus.”

The president wasn’t  40 . Instead, he was shocked. “Madam,” he said, “we can’t put up a statue for every person who studied at Harvard and died. If we did, this   41_  would look like a cemetery（墓地）,” “Oh, no,” the lady  42  quickly. “We don’t want to put up a statue. We would like to give a  43  to Harvard.” The president rolled his eyes and  44  at the couple and then exclaimed（惊叫）, “ A building! Do you have any  45_  how much a building costs? We have spent over ＄7,500,000 on the campus building at Harvard.” For a moment the lady was silent. The president was  46  , because he could get rid of them now. Then the lady turned to her husband and said quietly, “Is that all it costs to start a  47  ? Why don’t we just start our own?” Her husband nodded.  48_ their offer was turned down, Mr. and Mrs. Stanford traveled to California where they founded the University that bears their  49  , a memorial to a son that Harvard no longer  50  about.
