A new study warns that about thirty percent of the world 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 and 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.

　　PAI researchers Robert Engel says by the year 2025,about three thousand million people lack water. At least 18 more countries are, expected to have serious water problems. The demand for water keeps increasing. Yet the amount of water on the earth stays the same.

　　Mr. Engel 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 increase.

　　The report says lack of water in the future may result in several problems. It may increase health problem. Lack of water often means drinking water is not safe. Mr. Engel says there are problems all over the world be cause of diseases such as cholera（霍乱）that is carried in water.

　　Lack of water also results in more international conflict（冲突）. Countries may have to fight for water in the future. Some countries now get sixty percent of their 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 to improve their economics. This is because new in dustries often need large amounts of water when they are beginning.

　　The Population Action International study gives several solutions（解决方法）to the 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 is to use less water for agriculture.

　　The report also says long-term solution to the water problem must in clued controls on population growth.

　　On May 21, 2000, some American scientists were working at the computers to look for information they needed . Suddenly they saw a lot of very bright red spots crossing the computers’ screens. At the same time the computers were working much slower. To find out what was happening they stopped their work to check some parts of the computers. To their horror, they found out that most of their stored information was got rid of by computer viruses (病毒). Obviously all these computers had been infected by computer viruses.

It is said that the computer viruses were made by two or three Philippine young men fond of playing tricks. They all had excellent education. They created the viruses just to show their intelligence. The kind of computer virus is named I Love You Virus. This virus can hide in computers for long. When the time comes they will attack the computers by lowering the important functions, damaging their normal programs or even getting rid of a great deal of information which operators of the computers often use or store, what’s worse, it still can reproduce itself in great quantities within a short time.

We come to know that “I Love You” Virus often attacks computers on Mondays and that it is spreading to many computers in the world. Among the countries that suffered computer viruses last year are Britain, Australia, Switzerland and the USA. Those who made the computer muses have been found out slowly and carefully. But till now, how to get rid of the terrible viruses remains a problem.

1.When the viruses attack the computers, the computers will work _______.

　　A. normally　B. abnormally　C. faster　D. well

2 .Two or three Philippine young men created the computer viruses to _______.

　　A. damage the computers

　　B. test their ability quickly

　　C. tell the world that they were intelligent

　　D. play a trick in operators of the computers

3. According to the passage, computer viruses seem to________.

　　A. have been in nature for years

　　B. exist in any computers

　　C. be able to be got rid of in the near future

　　D. be difficult to get rid of at present

4.The most serious damage caused by the viruses is that_______.

　　A. the computer’s funtions are lowered

　　B. the normal programs are damaged

　　C. all the information stored in the computers is gone

　　D. the computers infected by the viruses can no longer be used

5. According to the passage, which of the following is true?

　　A. Scientists are trying to find a way to get rid of the viruses.

　　B. The viruses will come to the new computer after staying in the old one for some time.

　　C. Last year four countries found their computers were infected by 　　viruses.

　　D. The “I Love You” Virus is a great harm to human health.

Humanity uses a little less than half the water available worldwide. Yet occurrences of shortages and droughts (干旱) are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the world’s population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis.
　 But that doesn’t have to be the outcome. Water shortages do not have to trouble the world---if we start valuing water more than we did in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want.
　 Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs.
　 Governments should also protect this resource by providing water in more economically and environmentally sound (健康的) ways. For example, often the cheapest way to provide irrigation water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions (凹地) and pumping it to nearby cropland.
　 No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate (调整) water policy.
