10、ored and smelly,you know the river has been polluted, and there are four main possible causes for it.First, fertilizer. If large amounts of fertilizer or farm waste drain into a river, the concentrations of nitrate and phosphate in the water increase considerably.Algae use these substances to grow r
11、apidly, turning the water green.This massive growth of algae leads to pollution. When the algae die, they are broken down by the action of the bacteria, which quickly multiply, using up all the oxygen in the water and therefore causing the death of fish.Second, industrial waste. Factories sometimes
12、discharge chemical waste into rivers. Examples of such pollutants include cyanide, lead, copper, and mercury. These substances may enter the water in such high concentrations that fish and other animals are killed immediately. Sometimes the pollutants enter the food chain and accumulate until they r
13、each toxic levels, eventually killing fish and other animals.Third, oil pollution. If oil enters a slow-moving river, it forms a rainbow-colored film over the entire surface, preventing oxygen from entering the water.Fourth, warm water. Industry often uses water for cooling processes, sometimes disc
14、harging large quantities of warm water back into rivers. A higher temperature of the water lowers the level of dissolved oxygen and upsets the balance of life in the water.Keys:1.D 2.A 3.B 4.C 5.DTask3: Curbing carbon emissionsScript:Although it is not an easy task, China is striving to fulfill the
15、promise to cut its carbon dioxide emissions per unit of GDP by 40 to 45 percent in the next 10 years.Zhang Guobao, Director of the National Energy Administration, said, “The government puts great emphasis on seeking harmonious development between cities and the environment, and is readjusting the en
16、ergy structure by giving priority to the development of clean and low-carbon energies, including hydroelectric, nuclear, wind, and solar power.“Government authorities have closed small, coal-fired plants with a total capacity of 60.06 million kilowatts in the past four years. This years target of cl
17、osing 10 million kilowatts of capacity will be achieved by August.“We have promised to the international community that 15 percent of our power will be generated from nonfossil sources by 2020,“ Director Zhang said. At present, non-fossil energy accounts for only 7.8 percent.China is making efforts
18、to increase the proportion of clean energy in its total energy consumption. Statistics show that China invested US$34.6 billion in clean energy last year, exceeding the United States which invested US$18.6 billion. Thus, China has become the world leader in generating clean energy. Five years earlie
19、r, Chinas investment in clean energy was only US$2.5 billion.However, Chinas carbon emission reduction target cannot be achieved easily. The shift to a low-carbon economy might be met at a cost to society. For instance, more than 400,000 people were laid off as a result of the shutdown of small coal
20、-fired power plants in the past four years. Many studies indicate that the effort to curb greenhouse gas emissions may delay Chinas development, affect peoples income, and lead to unemployment.Keys:1.D 2.D 3.A 4.B 5.CIV.

Two speakers hold a negative attitude toward the world climate confe
26、rence. Task 3:Lets group work!Developed countries should bear more responsibilities. First, they caused most of the world pollution in their industrialization process. Second, they are already economically advanced, with more funds to deal with pollution problems. On the other hand, developing count
27、ries caused less pollution in the past, and now they need rapid development. Therefore, an international agreement the Kyoto Protocol in 1997 stipulated common but differentiated responsibilities for developed and developing nations, which means that both should be responsible for environmental prot
28、ection and cut carbon dioxide emissions, but the former must take more responsibility. Recently, however, some wealthy countries have insisted that developing countries like China should shoulder more responsibilities. VI. Further Listening and SpeakingListening Task:Task1: The environment and the d
29、evelopment Script:Li:Hi, Professor Wang. Im Li Lin, a correspondent for the university newspaper. The staff and students here are getting more and more interested in the relationship between the environment and economic development. What do you think is the most serious environmental problem at pres
30、ent? What measures should we adopt to improve the environment and develop the economy at the same time? Wang: There are many environmental problems: air pollution, water pollution, desertification, overfishing, destruction of natural habitats, acid rain, overconsumption of wild animals and plants, e
31、tc. But lying at the center of all those problems, as I see it, is the contradiction between economic growth and the environment.Since the United Nations Earth Summit in 1992, growing number of people and governments have adopted the new idea of “sustainable development“. This means todays economic
32、growth should not wipe out the resources and options for future generations. Planning and development should ensure not only economic growth, but also social advancement and environmental health. In other words, some economic behavior must be restricted or controlled. Instilling principles of sustai
33、nable development into government planning, resource management and economic policy is the most important step China can take to solve its environmental problems.China has already taken some remarkable steps to reduce damage to the environment. For instance, following the huge floods of 1998, the go
34、vernment banned logging in the upper reaches of the Yangtze River in order to protect forests and reduce the risk of floods.Still, the basic contradiction between the environment and development persists. Much work is to be done before we can achieve the aim of a balance between economic growth and
35、the environment.

36、cloud of pollution covering southern Asia threatens the lives of millions of people. Scientists say the pollution could increase lung disease and cause early death. The cloud is also damaging agriculture and affecting rainfall levels. It has affected many countries in southern Asia. The pollution cl
37、oud is three kilometers high. Scientists say it can move halfway around the world in a week.The cloud is the result of forest fires, the burning of agricultural waste, and huge increases in the burning of fuels by vehicles, industries, and power stations.Pollution from millions of bad cooking stoves
38、 has made the problem worse. Many poor people burn fuels like wood and animal waste in such stoves.Scientists say the cloud of pollution appears to cool the land and oceans by blocking sunlight. They say it reduces the amount of sunlight reaching the Earths surface by as much as 15 percent.At the sa
39、me time, heat inside the cloud warms the lower parts of the atmosphere.Harmful chemicals from the cloud are mixing with rainfall. This acid rain damages crops and trees and threatens public health. Scientists are concerned that the pollution will intensify during the next 30 years as the population
40、of Asia increases to an estimated 5,000 million people. Keys:1.D 2.B 3.A 4.C 5.CTask3: Mountain regions face a number of dangersScriptMountain people around the world are in great danger of the negative effects of the worsening environment, according to a UN report.As global warming and deforestatio
41、n accelerate and technology makes wilder places more accessible, environmental and social pressures on the worlds remotest regions increase.The UN has found that many mountainous regionsinhabited by one out of five of the worlds peopleare barely recognizable when they are compared to what they were
42、like 60 years ago.This is mostly because forests were cut to make way for cattle grazing and agriculture.The authors of the UN study expect 98 percent of the mountain areas to experience severe climate change by 2055.Biological losses are expected to be heavy. The mountains of Europe, parts of Calif
43、ornia and the northwest Andes in South America are among the most threatened mountain areas in the world and should be given priority in conservation.The UN is anxious to raise awareness of the problems facing mountain areas because they are inhabited by some of the most vulnerable people. These peo
44、ple could lose their culture and their livelihood with even the smallest shifts in climate.At the same time, many mountain regions are losing people. Thousands of villages in Europe are deserted most of the year. In other areas like Nepal, people are drifting to the cities in search of work. Keys: (

46、most of the year Viewing and speaking:Task 1:Santas home town in dangerScriptWeather experts may have found a new problem caused by global warming, one which many people will pay attention to: There are signs that Santas home in the North may be in trouble because of warmer temperatures.The Finnish
47、town of Rovaniemi on the Arctic Circle, which many Europeans say is the home of Santa Claus, has had its warmest winter in 40 years.As a result, there has been much less snow than usualmeaning no snowmen, no snowballs, and possibly not enough snow for Santa to ride his sleigh on.More important for l
48、ocal residents, it may mean fewer tourists, as well. Santas wintry home town normally attracts thousands of visitors each year, and millions of dollars.Anne Pelttari-Bergman, the towns tourist director, worries that the town could be in trouble if snow levels do not return to normal. She explains: “
49、Snow is really important for us, of course, for Santa Claus, for Christmas tourism, and also for our winter tourism because winter is our best season. It is really important for us.“Weather experts and town residents are hoping this warm winter is an one-time thing. Few people can imagine a holiday when even Santa does not have a white Christmas.
