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 (調(diào)整) water policy.

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.

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(水庫)

  D. is underestimated by government organizations at different levels

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

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

  A. guarantee full protection of the environment

  B. centralize the management of water resources

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

D. encourage local and regional water resources

THIS was the year the Earth struck back.

Earthquakes, heat waves, floods, volcanoes, super typhoons, snow storms, landslides and droughts killed at least a quarter of a million people in 2010 – the deadliest year in more than a generation. More people were killed worldwide by natural disasters this year than have been killed in terrorism attacks in the past 40 years combined.

"It just seemed like it was back-to-back and it came in waves," said Craig Fugate, who heads the U.S. Federal Emergency Management Agency. It handled a record number of disasters in 2010.

And we have ourselves to blame most of the time, scientists and disaster experts say.

Even though many catastrophes have the ring of random chance, the hand of man made this a particularly deadly, costly, extreme and weird(古怪的) year for everything from wild weather to earthquakes.

Poor construction and development practices conspire to make earthquakes more deadly than they need be. More people live in poverty in vulnerable(脆弱的) buildings in crowded cities. That means that when the ground shakes, the river breaches, or the tropical cyclone hits, more people die.

Disasters from the Earth, such as earthquakes and volcanoes "are pretty much constant," said Andreas Schraft, vice president of catastrophic perils for the Geneva-based insurance giant Swiss Re. "All the change that's made is man-made."

The January earthquake that killed well more than 220,000 people in Haiti is a perfect example. Port-au-Prince has nearly three times as many people - many of them living in poverty - and more poorly built shanties than it did 25 years ago. So had the same quake hit in 1985 instead of 2010, total deaths would have probably been in the 80,000 range, said Richard Olson, director of disaster risk reduction at Florida International University.

In February, an earthquake that was more than 500 times stronger than the one that struck Haiti hit an area of Chile that was less populated, better constructed, and not as poor. Chile's bigger quake caused fewer than 1,000 deaths.

Climate scientists say Earth's climate also is changing, bringing extreme weather, such as heat waves and flooding.

In the summer, one weather system caused oppressive heat in Russia, while farther south it caused flooding in Pakistan that inundated 161,200 square kilometers, about the size of Wisconsin. That single heat-and-storm system killed almost 17,000 people, more people than all the worldwide airplane crashes in the past 15 years.

Scientists have calculated that the killer Russian heat wave—setting a national record of 43.9℃—would happen once every 100,000 years without global warming.

What is responsible for the most human deaths in 2010?

A.Natrual disasters.       B.Terrorist attacks.

    C.Poor buildings.      D.Too rapid developrnent.

According to Andreas Schraft,             .

A.earthquakes are happening more often because of human beings

B.earthquakes are causing more damage because of human beings

C.stronger houses should be built to limit storm damage

D.Port—au—Prince is now overpopulated

The main point of the article is to           

A.list the natural disasters that occurred in 2010

B.give the details of some natural disasters of 2010

C.warn that more natural disasters are to strike

D.blame humanity for not helping those affected by the disasters

Aimlessness has hardly been typical of the postwar Japan whose productivity and social harmony are the envy of the United States and Europe. But increasingly the Japanese are seeing a decline of the traditional work-moral values. Ten years ago young people were hardworking and saw their jobs as their primary reason for being, but now Japan has largely fulfilled its economic needs, and young people don't know where they should go next.
The coming of age of the postwar baby boom and an entry of women into the male-dominated job market have limited the opportunities of teenagers who are already questioning the heavy personal sacrifices involved in climbing Japans rigid social ladder to good schools and jobs. In a recent survey, it was found that only 24.5 percent of Japanese students were fully satisfied with school life, compared with 67.2 percent of students in the United States. In addition, far more Japanese workers expressed dissatisfaction with their jobs than their counterparts did in the ten other countries surveyed.
While often praised by foreigners for its emphasis on the basics, Japanese education tends to stress test taking and mechanical learning over creativity and self-expression." Those things that do not show up in the test scores, personality, ability, courage or humanity are completely ignored," says Toshiki Kaifu, chairman of the ruling Liberal Democratic Party's education committee." Frustration against this kind of thing leads kids to drop out and run wild." Last year Japan experienced 2,125 incidents of school violence, including 929 assaults on teachers. Amid the outcry, many conservative leaders are seeking a return to the prewar emphasis on moral education. Last year Mitsuo Setoyama, who was then education minister, raised eyebrows when he argued that liberal reforms introduced by the American occupation authorities after World WarⅡ had weakened the "Japanese morality of respect for parents."
But that may have more to do with Japanese life-styles." In Japan," says educator Yoko Muro, "it’s never a question of whether you enjoy your job and your life, but only how much you can endure." With economic growth becoming centralization, fully 76 percent of Japans, 119 million citizens live in cities where community and the extended family have been abandoned in favor of isolated, two generation households. Urban Japanese have long endured lengthy commutes (travels to and from work) and crowded living conditions, but as the old group and family values weaken, the discomfort is beginning to tell. In the past decade, the Japanese divorce rate, while still well below that of the United States, has increased by more than 50 percent, and suicides have increased by nearly one-quarter.
【小題1】 In the Westerners eyes, the postwar Japan was_____ .

A.under aimless developmentB.a(chǎn) positive example
C.a(chǎn) rival to the WestD.on the decline
【小題2】According to the author, what may chiefly be responsible for the moral decline of Japanese society?
A.Women's participation in social activities is limited.
B.More workers are dissatisfied with their jobs.
C.Excessive emphasis has been placed on the basics.
D.The life-style has been influenced by Western values.
【小題3】Which of the following is true according to the author?
A.Japanese education is praised for helping the young climb the social ladder.
B.Japanese education is characterized by mechanical learning as well as creativity.    
C.More stress should be placed on the cultivation of creativity.
D.Dropping out leads to frustration against test taking.
【小題4】The change in Japanese life-style is revealed in the fact that____.
A.the young are less tolerant of discomforts
B.the divorce rate in Japan exceeds that in the U.S.
C.the Japanese endure more than ever before
D.the Japanese appreciate their present life
