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.

1.What is the real cause of the potentials water crisis.

　　A. Only half of the world's water can be used.

　　B. The world population is increasing faster and faster.

　　C. Half of the world's water resources have been seriously polluted.

　　D. Humanity has not placed enough value on water resources.

2.As is indicated in the passage, the water problem _________ .

A. is already serious in certain parts of the world.

B. has been exaggerated by some experts in the field

　　C. poses a challenge to the technology of building reservoirs(水库)

　　D. is underestimated by government organizations at different levels

3. According to the author, the water price should _______ .

　　A. be reduced to the minimum        B. stimulate domestic demand

　　C. go with its real value             D. take into account the occurrences of droughts

4.In order to raise the efficiency of the water supply, measures should be taken to ______ .

　　B. centralize the management of water resources

　　C. increase the sense of responsibility of agencies at all levels

第二部分：阅读理解（共两节，满分50分）

第一节（共20小题，每小题2分，满分40分）阅读下列短文，从每题所给的四个选项A、B、C、D中选出最佳选项。

Judging from recent surveys, most experts in sleep behaviour agree that there is virtually an epidemic （流行病）of sleepiness in the nation. “I can’t think of a single study that hasn’t found Americans getting less sleep than they ought to,” says Dr. David. Even people who think they are sleeping enough would probably be better off with more rest.

The beginning of our sleep-deficit crises can be traced back to the invention of the light bulb a century ago. From diary entries and our personal accounts from the 18th and 19th centuries, sleep scientists have reached the conclusion that the average person used to sleep about 9. 5 hours a night. “The best sleep habits once were forced on us, when we had nothing to do in the evening down on the farm, and it was dark.” By the 1950s and 1960s, the sleep schedule had been reduced dramatically, to between 7. 5 and 8 hours, and most people had to wake to an alarm clock. “People cheat in their sleep, and they don’t even realize they’re doing it,” says Dr. David. “They think they’re okey because they can get by on 6. 5 hours, when they really need 7. 5, 8 or even more to feel ideally energetic. ”

Perhaps the most merciless robber of sleep, researches say, is the complexity of the day. Whenever pressures from work, family, friends and community increase, many people consider sleep the least expensive item on their programme. “In our society, you’re considered dynamic if you say you need only 5. 5 hours’ sleep. If you’ve got to get 8. 5 hours, people think you lack drive and ambition. ”

To determine the consequences of sleep-deficit, researchers have put subjects through a set of psychological and performance tests requiting them, for instance, to add columns of numbers or recall a passage read to them only minutes earlier. “We’ve found that if you’re in sleep deficit, performance suffers,” says Dr. David. “Short-term memory is weakened, as are abilities to make decisions and to concentrate. ”

41. What is the main topic of the passage?

A. Research on the causes and consequences of sleep-deficit.

B. The epidemic of sleepiness in the modern times.

C. The history of people’s sleeping patterns.

D. The minimum of our sleeping hours.

42. Which of the following is Dr. David’s opinion?

A. People who think they are sleeping enough are better off than those who don't.

B. Some people can remain energetic with only 6. 5 hours’ sleep a night.

C. If they get 8. 5 hours’ sleep, people will be full of drive and ambition.

D. People’s metal power suffers if they are lacking in sleep.

43. People in the 18th and 19th centuries slept about 9. 5 hours a night because _______.

A. they were forced by their parents to do so

B. they knew what was best for their health

C. they had no electricity

D. they were not so dynamic and ambitious as modern people are

44. What does the word “subjects” in paragraph 4 mean?

A. Persons or things being discussed or described.

B. Branches of knowledge studied in a school.

C. Persons or things being treated in a certain way or being experimented on.

D. Any member of a state apart from the the supreme ruler.
