解析：
录音中指出大约one third of the world’s population生活在有“水资源压力”的国家，在这些国家“consumption exceeds 10 per cent of total supply”，也就是说水资源供不应求，因此题干表述与录音内容相一致。fall short of达不到；缺乏。
【录音原文】
Global freshwater consumption rose sixfold between 1900 and 1995—more than twice the rate of population growth. About one third of the world’s population already lives in countries considered to be “water stressed”—that is, where consumption exceeds 10 per cent of total supply. If present trends continue, two out of every three people on Earth will live in that condition by 2025.

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

What is the 'biggest city in the world? That is, (21) city has the largest population? This seems like (22) question to answer, but actually it isn't.It's actually rather difficult to say which cities (23) the largest. There are two reasons for this difficulty. First of all, it isn't easy to determine a city's boundaries, that is, where a city ends. Nowadays, nearly all cities have a large (24) area around them. So when we talk about the population of a city, we often mean the population of the whole metropolitan area around the city. That means that it's difficult to determine what the population of a city is because it's difficult to define what a city is.The second reason that it is difficult to 25 the population of different cities is this: it is almost impossible to get (26) about the population of all cities for the same year. For example, we might get an estimate of New York's population in 1979 and an (27) of Mexico City's population in 1981. So we real ly can't compare the numbers because the information is for (28) different years. And the population of cities changes rather quickly, especially in some cases. For example, the population of Jakarta, Indonesia, may increase by 5% each year, so the population figure will change rather quickly.So we can say that these are our two (29) for comparing the populations of cities: one, it's difficult to determine the (30) of a city, and two, it is difficult to get accurate information.21.

Australia is the world's smallest continent and largest island, a relatively young nation established in an ancient land. Its development represents a triumph(胜利)over remoteness and a harsh landscape.It is generally accepted that Australia's original inhabitants, the aboriginal(土著的)people, have lived on the continent for 40,000 to 60,000 years. They were also its sole(唯一的)human inhabitants until two centuries ago. Indonesian traders probably visited Australia's northwest but it was unknown to the rest of the world until the 1600s. A huge south land appeared on maps before 200 AD but its existence was not confirmed until the 17th century when Portuguese, Spanish and Dutch merchants ventured into Asia.The first European settlement of the continent--by the British--began in 1788, on the site now occupied by Sydney, Australia's largest city. There were then about 1500 Europeans and an estimated 300,000 aboriginal people in Australia. The population has reached 2.25 million by 1881, 5.41 million by 1921 and 7.4 million by the end of World War II(1945). It increased sharply, partly because of a large postwar immigration program, and reached more than 17 million in 1991, despite a decline that began in the 1970s in the natural increase and net immigration. The rate of population increase in the 40 years after world war II, about two percent, has halved.Australia is one of the most urbanized countries in the world, with about 70 percent of the population living in the 10 largest cities. Australians have a high standard of living by world standards. The flag of Australia is the only one to fly over a whole continent in the world. The small Union Jack represents the historical link with Britain, the largest star has six points for each of the states and one point for the territories, and the small stars form. the Southern Cross - a prominent of the southern hemisphere night sky.1. The passage is written to _____.A. present a general picture of AustraliaB. persuade people to travel in AustraliaC. tell people the history of AustraliaD. describe the characteristic of Australia2. The first sentence in paragraph 1 mainly suggests that _____.A. Australia is a strange countryB. it is not easy to find AustraliaC. Australia has contradictory(矛盾的)featuresD. Australia is a continent and a country as well3. Which statement about Australia's population can NOT be inferred? _____A. The population change is a gradual increase.B. The population increased rapidly for a time owing to the government's special policy.C. The rates of population increase in different periods varied.D. The rate of population increase before World War II was about one percent.4. The word urbanized means _____.A. of towns or citiesB. of emergencyC. of suburbsD. of the countryside5. Which of the following statements is NOT true? _____A. The large star on the flag of Australia has seven points.B. People were certain of Australia's existence before 200 AD because it had appeared on maps.C. Australia enjoy relatively high standard of living compared with people in other countries.D. The aboriginal people of Australia were its only human inhabitants before the 18th century.

Passage ThreeQuestions 31 to 35 are based on the following passage.An understanding of man's effect on the balance of nature is crucial (关键的) to being able to find the appropriate remedial action. It is a very common belief that the problems of the population explosion are caused mainly by poor people living in poor countries who do not know enough to limit their reproduction. This is not true. The actual number of people in an area is not as important as the effect they have on nature. Developing countries do have an effect on their environment, but it is the populations of richer countries that have a far greater impact on the earth as a whole.For example, tropical forests are known to be essential to the balance of nature, yet we are destroying them at a great rate. They are being cleared not to benefit the natives of that country, but to satisfy the needs of rich countries. Central American forests are being destroyed for grassland to make pet food in the United States cheaper; in Papua slew Guinea, forests are destroyed to supply cheaper cardboard packaging for Japanese electronic products; in Burma and Thailand, forests have been destroyed to produce more attractive furniture in Singapore and Hong Kong. Therefore, a rich person living thousands of miles away may cause more tropical forest destruction than a poor person living in the forest itself.In short, it is everybody's duty to safeguard the future of mankind—not only through population control, but by being more aware of the effect his actions have on nature. Nature is both fragile and powerful. It is very easily destroyed; on the other hand, it can easily destroy its most dangerous enemy—man.31.According to the first paragraph, people usually believe that .A.poor people in poor countries contribute to the imbalance of natureB. rich people know how to protect the environment by taking actionsC. people in poor areas know a lot about the birth controlD. rich people in rich countries have done a lot to balance nature

单选题Since 1960, the fast-growing town of Hotstone, Arizona, has drawn water from the Gray River, which feeds Lake Mudfish. If the town’s water use continues to grow at its present rate, in about 20 years the water level of Lake Mudfish will inevitably decrease to the point that it can no longer support its biologically fragile population of fish. The prediction above is based on which of the following assumptions?A
As the town’s water requirements grow, it will not be able to meet those requirements by drawing on water sources other than the Gray River.B
Since 1960, the lake’s population of fish has become more biologically fragile.C
The amount of water that the lake loses to evaporation each year will increase over the next two decades.D
There are multiple sources of water besides the Gray River that feed into Lake Mudfish.E
The town of Hotstone will be able to reverse its trend of increasing water use if it implements an aggressive water conservation program.

问答题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.

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.
