Practice 5 Water is essential for life. Yet many millions of people around the world face water shortages. Many millions of children die every year from water-borne diseases. And drought regularly afflicts some of the world’s poorest countries. The world needs to respond much better. We need to increase water efficiency, especially in agriculture. We need to free women and girls from the daily chore of hauling water. We must involve leaders of countries in decision-making on water management. We need to make sanitation a priority. This is where progress is lagging most. And we must show that water resources need not be a source of conflict. Instead, they can be a catalyst for cooperation. Significant gains have been made. But a major effort is still required. Our goal is to meet the internationally agreed targets for water and sanitation by 2015, and to build the foundation for further progress in the years beyond. This is an urgent matter of human development, and human dignity. Together, we can provide safe, clean water to the entire world’s people. The world’s water resources are our lifeline for survival, and [or sustainable development in the 21st century. Together, we must manage them better.

EThe need to feed a growing population is putting much pressure on the world’s supply of water. With 97% of the world’s water too salty to be drunk or used in agriculture, the worldwide supply of water needs careful management, especially in agriculture. Although the idea of a water shortage（短缺）seems strange to someone fortunate enough to live in a high rainfull country, many of the world’s agricultural industries experience constant water shortages.Although dams can be built to store water for agricultural use in dry areas and dry seaons, the costs of water redistribution(重新分配)are very high. Notonly is there the cost of the engineering itself, but there is also an environmental cost to be considered. Where valleys(山谷)are flooded to create dams, houses are lost and wildlife homes destroyed. Besides, water many flow easily through pipes to fields,but it cannot be transported from one side of the world to the other. Each country must therefore rely on the management of its own water to supply its farming requirements.This is particularly troubling ro countries with agricultural industries in areas dependent on irrigation（灌溉）. In Texas, farmers’ overuse of irrigation water be resulted in a 25% redcution of the water stores. In the Central Valley area of south eastern USA, a huge water engineering project provided water for farming in dry vallege, but much of the water use has been poorly managed.Saudi Arabia’s attempts to grow wheat in desert areas have been the pumping of huge quantities of irrigation water from underground reserves. Because there is no rainfall in these areas, such reserves can only decrease, and it is believed that fifty years of pumping will see them run dry.72. From the first two paragraphs we learnt that _______.A.much of the world’s water is available for useB.people in high rainfll countries feel luckyC.the costs of water redistribution should be consideredD.water can be easily carried through pipes across the world

BThe world is not only hungry，it is also thirsty for water． this may seem strange to you，since nearly 75% of the earth is covered with water． But about 97% of this water is sea water．Man can only drink and use the other 3% fresh water that comes from rivers，lakes，under-ground and other places． And we cannot even use all of that，because some of this fresh water has been made dirty．At the moment，this small amount(数量) of fresh water is still enough for us． However，our need for water is getting greater and greater． Only if we take steps to solve this problem now，we can get away from a serious world water shortage later on． The people of the world cannot have an enjoyable life without enough clean water．On one hand we should stop wasting this little water of ours，on the other hand we should find ways to reuse it，but this has not been done widely．Today，in most large cities，water is used only once and it then returns to the sea or runs into underground places．lf we can make it clean again，it can be used once more just as if it were fresh from a spring．But even if large cities reuse its water，we still would not have enough in the future． Where．could we turn to next for water? To the ocean! How can we do to make use of this great a-mount of sea water? We can take the salt from the water to make it fresh．So if we take all these steps，we'll be in no danger of drying up!( )26． Why does the writer say that the world is thirsty for water?A． The amount of fresh water is really very small．B． The people of the world waste too much water．C． The people of the world have to drink a lot of water every day．D． There are too many people in the world needing water．

Passage ThreeQuestions 31 to 35 are based on the following passage.One of the most exciting races ever run is now in progress between doctors fighting malaria(疟疾)and mosquitoes. According to the most recent counts 225 million people a year suffer attacks of malaria and more than two million die. Public health workers around the world are doing all t11ev can to destroy malaria before the mosquitoes that pass on the disease become resistant to the poisons now used against them. It's a race against time and against difficulties，with millions of lives in danger and the chances of winning not in man's favour.Malaria，it is true，has been practically wiped out in thirteen countries. including the United States，and is under attack in many others. But it is equally true that in some parts of the world certain types of malaria-carrying mosquitoes have already learned to resist some of the sprays that formerly killed them. Other types of mosquitoes are not killed as quickly by present sprays as they once were.The World Health Organization is helping national governments to get rid of malaria before resistance among the mosquito population becomes so great that new poisons will have to be found to replace those in use at present. Most of the countries in the world have started，or are planning，campaigns against mosquitoes. If the race against resistance is won by man，it is possible that ten years from now dais old evil will have disappeared completely from the America，perhaps from the world.Malaria has been successfully got. rid of in______.A. all countriesB. some countriesC. no countriesD. most countries

Water一the Issue of This CenturyThe world is running short of freshwater. Populations are growing bigger and thirstier （渴的）,with the result that freshwater is becoming increasingly scarce（缺乏）.Half the world's wetlands have disappeared during the last century,while estimates suggest that wa- ter use will rise by 50% in the next 30 years.The World Bank report estimates that as much as half of the world's population,concentrated in Africa,the Middle East and south Asia,will face“severe water shortages”by 2025.Local water conflicts and the loss of freshwater ecosystems appear large in some re- gions.A similar picture emerges from the globe's salt water regions. Three-quarters of the world's people may live within 100km of the sea in 2025,putting even more pressure on stretched coastal ecosystems. Two thirds of fisheries（渔业）are exploited at or beyond their sustainable limits, and half the world's coral reefs（珊瑚礁）may perish in 100 years. Almost 60% of coral reefs and 34% of fish species are at risk from human activities,the Bank says.The report concludes that there is ample evidence to justify immediate and coordinated action to safeguard supplies and use water more efficiently.Fresh water consumption is rising quickly,and the availability of water in some regions is likely to become one of the most pressing issues of the 21st century.A third of the world's popu1ation一around two billion people一live in countries that are experiencing moderate to high water shortages.That proportion could rise to half or more in the next 30 years unless institutions（制度）change to ensure better conservation and alloca- tion of water.China is one country where the portents（征兆）are gloomy. The most waterstressed country in East Asia,China is exploiting 44%of its usable water,a figure projected to rise to6O%by 2020.Primary withdrawal of water of more than 60%is widely considered by water experts to exceed the environmental carrying capacity of a river basin system. AlthoughChina's total use appears still to be reasonable,it has several basins that are severely stressed environmentally.Withdrawals exceed environmental limits in Afghanistan and Pakistan,and will exceed them in India by 2020.In the Middle East and North Africa,only Morocco has unexploited water resources.The rest have exceeded environmental limits and many are mining aquifers （蓄水层）一bodies of water-bearing rock一the report says.Most of the world's population may live within 100km of the sea in 2025.A: RightB: WrongC: Not mentioned

问答题Practice 5 Never has there been a language quite like English. A bold statement, yet nevertheless true. Consider a few statistics. Today, one out of every seven people in the world use English in some way. More than half the world’s books are written in English; the majority of international telephone calls are made in English; 60% of the world’s radio programs are broadcast in English. English is even the working language of international air travel. For the first time in history, a single language has become dominant across a wide range of human activity, ranging from music, film and fine arts to the fields of business, diplomacy, science and technology.

问答题Practice 10 The momentum is building ahead of next month’s G8 summit in Scotland where the leaders of the world’s richest nations will debate what they can do to help some of the world’s poorest. Africa is the priority and the politicians will discuss reducing the debt burden, ending trade regulations which put the continent’s economy at a disadvantage, and giving more aid. Mark Doyle, who’s reported from Africa for many years, looks at why aid is necessary, and why much of what’s been donated in the past has not worked. All around the edge of Africa-along the coastline, near the continents’ ports—are monuments to exploitation. On the island of Goree, for example, just off the coast of Senegal, there’s: the Slave House. This was the last place many Africans saw before being shipped off to a lifetime of slavery in American or, just as often, to death on the high seas. There are many more places like this dating from the three hundred and fifty years or so of the African slave trade. When people wonder why Africa is so poor, they need look no further for the start of an explanation.

问答题Practice 4 The line of demarcation between the adult and the child world is drawn in many ways. For instance, many American parents may be totally divorced from the church, or entertain grave doubts about the existence of God, but they send their children to Sunday school and help them to pray. American parents struggle in a competitive world where sheer cunning and falsehood are often rewarded and respected, but they feed their children with nursery tales in which the morally good is pitted against the bad, and in the end the good inevitably is successful and the bad inevitably punished. When American parents are in serious domestic trouble, they maintain a front of sweetness and light before their children. Even if American parents suffer a major business or personal catastrophe, they feel obliged to turn to their children and say, “Honey, everything is going to be all right.” This American desire to keep the children’ s world separate from that of the adult is exemplified also by the practice of delaying transmission of the news to children when their parents have been killed in an accident. Thus, in summary, American parents face a world of reality while many of their children live in a near-ideal unreal realm where the rules of the parental world do not apply, are watered down, or are even reversed.

问答题Pollution is a problem because man, in an increasingly populated and industrialized world, is upsetting the environment in which he lives. Many scientists maintain that one of man’s greatest errors has been to equate growth with advancement. Now “growth” industries are being looked on with suspicion in case their side effects damage the environment and disrupt the relationship of different forms of life. The growing population makes increasing demands on the world’s fixed supply of air, water and land. This rise in population is accompanied by the desire of more and more people for a better standard of living. Thus still greater demands for electricity, water and goods result in an ever increasing amount of waste material to be disposed of.The problem has been causing increasing concern to living things and their environment. Many believe that man is not solving these problems quickly enough and that his selfish pursuit of possessions takes him past the point of no return before be fully appreciates the damage.
