Passage

　　Humanity uses a little less than half the water available worlide.Yet occurrences of shortages and droughts(干旱) are causing famine and distress in some areas,and industrial and agriculturalbyproducts 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 don't have to trouble the world—if we start valuing water more than we have 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 aswe 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 ways.For example,often the cheapest way to provide irrigation(灌溉) water in the dry tropics is through smallscale projects,such as gathering rainfall in depressions(洼地) and pumping it to nearby crop land。

　　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 water supply.

　　1.What is the real cause of the potential 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 sufficient value on water resources.

　　2.As 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

　　D.is understated by government organiations at different level

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

　　A.be reduced to the minimumB.stimulate domestic demand

　　C.correspond to its real valueD.take into account the occurrences ofdroughts

　　4.The author says that in some hot and dry areas it is advisable to ——.

　　A.build big lakes to store water

　　B.construct big pumping stations

　　C.build small and cheap irrigation systems

　　D.channel water from nearby rivers to cropland

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

　　A.guarantee full protection of the environment

　　B.centralie the management of water resources

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

　　D.encourage local and regional control of water resources

　　Passage

　　People in Shanghai can quench their thirst(解渴) with high quality water if the Shanghai Water Authority (SWA) is able to make good on its word.It has vowed(发誓) to make the city's water match its status as a worldclass city。

　　“The current tap water quality meets national standards,but,compared with that of the European Union and the United States,it still needs to be improved,”said the SWA's director general,hang Jiayi.

　　The Shanghai Special Water Supply Layout calls for residents to be able to drinkthe tap water without boiling it,in less than a decade.

　　In other developed countries,water fountains can be found almost everywhere—people do not bother with bottled drinking water.

　　By 2020,the water of the Huangpu River will be treated to reduce the amount of organic(有机物的) waste in it.This initiative(倡议) is to be completed in the first half of this year,hang said.

　　Major water works that draw water from the Huangpu will need more treatment facilities to improve the color,texture(结构),ammonia(氨)and nitrogen(氮) content before 2010.

　　These treatment facilities are expected to cost 4 billion yuan,something that could affect the price of water,according to Chen Yin,SWA's deputy director general.

　　Chen said that replacing water pipes was also a key project.The city's aged pipes are mostly to blame for the bad water quality.

　　The SWA has started the water facilities renovation(整修) work,including the more than 14,000 kilometers of indoor piping,107,000 tanks on top of the buildings,and more than 6,000 underground facilities.

　　World Water Day came on March 22,and this year's theme is“water for the future”.Beijing is also drawing up plans during China's Water Week,which runs until March 28.

　　By 2008,the water for the Olympic Games is to above World Health Organiation standards.And,the people of Beijing will be able to drink their tap water as well.

　　参考答案：

　　Passage

　　1.细节题。潜在的水危机的真正原因是什么?四个选项分别是：选项A世界上的水只有一半可以利用;选项D世界人口增长越来越快;选项C世界水源的一半已被污染;选项人类对水源还没有足够的重视。相关信息在第一段最后一句：因世界人口在未来的50年里翻一番，所以许多专家认为我们正处于大范围水危机的边缘。接着，第二段前两句语气一转说：但是结果未必如此。如果我们现在开始珍视水，水短缺也许不会令世界不安。就像20世纪70年代石油危机后开始珍视石油一样，今天我们必须以一种新的经济视角来看待水。根上面的陈述，答案为D。

　　2.推断题。正如文章所述，水问题：选项A在世界的某些地方已是严重的问题;选项B被这个领域的一些专家夸大;选项C对建造水库的技术提出了质疑;选项D被不同级别的政府部门低估。根据文章首段第一句和第二句：虽然人类用水量还不到世界现有水的一半，但是一些地区的饥荒和困境却是缺水和干旱造成的。既然饥荒和困境因缺水和干旱而起，显然水问题已是一个不容忽视的问题。答案为A。

　　3.由第三段第1句可知，答案为C。
