6、InTask 1: We should have proper respect for nature!ScriptMartha: Do you think most people in your culture respect nature?Ed: I think so. Um more now than before.Martha: What do you think is the most serious environment problem in the world today?Ed: TodayI think damage to the ozone layer is a big pr

7、oblem, and another problem is pollution in big cities and things like that.Martha: How do you learn about environmental problems?Ed: Um through school. A lot of clubs promote environmental safely, and some TV programs, too. They talk about environmental safely and stuff like that.Martha: Do you thin

8、k students should learn more about the environment at school?Ed: I think so. So, as they grow older, they can be more aware of all the problems that are going on, and prevent more problems from occurring. Martha: If you could create a new law to help the environment, what would it be?Ed: A new law f

9、or the environment? UmId probably say that when people throw away their cigarette butts, they have to throw them into the garbage bin, not just throw them everywhere because its just littering and I hate that. So they should be fined if they throw them on the floor on the ground.Martha: Thats a good

10、 idea. What do you personally do to help protect the environment?Ed: I m so against littering. I never litter. If I see somebody litter, I get really angry. So I always throw my trash into the garbage bin.玛莎：你认为在你的文化中人们尊重大自然？艾德：我是这么认为的。嗯现在比以前更多。玛莎：你认为什么是当今世界最严重的环境问题？艾德：今天我想破坏臭氧层，是一个大问题，一个问题是在大城市的污染等

11、等。玛莎：你怎么了解环境问题？艾德：嗯通过学校。很多俱乐部促进环境安全，和一些电视节目，太。他们谈论环境安全的东西。玛莎：你认为学生应该在学校学会更多关于环境的问题吗？艾德：我是这么认为的。所以，当他们长大后，他们可以更清楚地了解所有的问题，要，并防止更多的问题。玛莎：如果你能创造新的法律帮助环境，它会是什么？艾德：对环境的新法律？嗯我可能会说，当人们扔掉的烟头，他们不得不把它们扔到垃圾桶，不随便乱扔垃圾，我憎恨这种行为。所以他们应该罚款如果他们扔在地板上。玛莎：那是个好主意。那么个人的事怎么来帮助保护环境呢？艾德：我非常反对乱扔垃圾。我从不乱扔垃圾。如果我看到有人乱扔垃圾，我真的生气了。所以

12、我总是把我的垃圾扔进垃圾箱。Key:Nature environmental problem pollution promote aware offrom occurring law throw away fined trashTask 2: River pollutionScriptIf you see dead fish floating on the river or notice that the water is discolored and smelly, you know the river has been polluted, and there are four main p

13、ossible causes for it.First, fertilize. If large amount of fertilize or farm waste drain into a river, the concentrations of nitrate and phosphate in the water increase considerably. Algae use these substances to grow rapidly, turning the water green. This massive growth of algae leads to pollution.

14、 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 discharge chemical waste into rivers. Examples of such pollutants include cyanid

15、e, lead, copper, and mercury. These substances may enter the river in such high concentrations that fish and other animals are killed immediately. Sometimes the pollutions enter the food chain and accumulate until they reach toxic levels, eventually killing fish and other animals.Third, oil pollutio

16、n. 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 discharging large quantities of warm water back into rivers. A higher temperature of

17、 the water lowers the level of dissolved oxygen and upsets the balance of life in the water.如果你看到死鱼漂浮在河上或发现水变色发臭，你知道那条河被污染了，和有四个主要的它可能的原因。第一，施肥。如果大量施肥或农场废物排入河中的水，大大增加的硝酸盐和磷酸盐的浓度。藻类利用这些物质的快速增长，将水绿色。这种大规模的藻类生长导致污染。当藻类死亡，他们打破了细菌的行动，并迅速繁殖，耗尽水中的氧气，导致鱼类死亡。第二，工业废水。工厂排放的化学废料排入河流有时。等污染物的例子包括氰化物，铅，铜，汞。这些高浓度物质

18、进入河中可能立即杀死鱼类和其他动物。有时，污染物进入食物链积累到有毒水平，最终杀死鱼类和其他动物。第三，石油污染。如果油进入流动缓慢的河流，它形成了一个彩虹色膜的整个表面，防止氧进入水。第四，温水。行业经常采用水冷却的过程，有时排出大量的温水回到河流。较高的水的温度降低溶解氧水平，使生命的水平衡。Question and key:What is the passage mainly about?D) The causes of river pollution.2. Why does the river water turn green?A) Because nitrate and phosph

19、ate in the water increase.3. What harm does industrial waste cause?B) Poisoning.4. Which of the following is true of oil pollution?C) It prevents oxygen from entering the water.5. What harm can warm water in a river bring?D) Lack of oxygen.1。本文的主要内容是什么？d）河流造成污染。2。为什么河水会变绿？一）因为在水增加硝酸盐和磷酸盐。3。工业废水造成什么危

Further Listening and SpeakingTask1: The environment and the developmentScriptLi: Hi Professor Wang, Im Li Lin, a correspondent from the university newspaper. The staff and students here are getting more and more interested in the relati

21、onship between the environment and economic development. What do you think is the most serious environmental problem at present? 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 polluti

22、on, desertification, overfishing, destruction of natural habitats, acid rain, overconsumption of wild animals and plants, etc. 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, g

23、rowing number of people and governments have adopted the new idea of “sustainable development”. This means todays economic 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 env

24、ironment health. In other words, some economic behavior must be restricted or controlled. Instilling principles of sustainable 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

25、 taken some remarkable steps to reduce damage to the environment. For instance, following the huge floods of 1998, the government 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 environment and

26、development persists. Much work is to be done before we can achieve the aim of a balance between economic growth and the environment.李：你好，王教授，我是李林，从大学报的记者。工作人员和这里的学生越来越多，在环境与经济发展之间的关系更感兴趣。你认为什么是目前最严重的环境问题？我们应该采取什么措施来改善环境，在发展经济的同时？王：有很多环境问题：空气污染，水污染，沙漠化，过度捕捞，自然栖息地的破坏，酸雨，野生动植物的过度消费，而躺在这些问题中，我认为，是经济增长和

27、环境保护之间的矛盾。联合国1992地球峰会以来，越来越多的人和政府都采取了“可持续发展的新理念”。这意味着今天的经济增长不应消灭的资源和未来的选择。规划和发展应确保的不仅是经济增长，但同时社会进步和环境健康。换句话说，一些经济行为必须受到制约。将可持续发展原则逐步纳入政府规划，资源管理和经济政策是最重要的一步，中国可以解决环境问题。中国已采取了一些重大措施来减少对环境的破坏。例如，1998的大洪水后，政府禁止砍伐长江上游为了保护森林和减少洪水风险。然而，环境与发展之间的基本矛盾依然存在。大量的工作是要实现经济增长与环境之间的平衡的目的了。Key:water pollution overcons

29、 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 cloud is three kilometers high. Scientists say it can move halfway around the

30、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 has made the problem worse. Many poor people burn fuels like wood and animal

31、 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 same time, heat inside the cloud warms the lower parts of the atmosphere.Scien

32、tists say this combination could be changing winter rainfall levels in Asia. They say rainfall has increased over the eastern coast of Asia. But it has dropped sharply over parts of northwestern Asia. The report says the cloud could reduce rainfall over northwestern Pakistan, Afghanistan, and western China by up to 40 percent.Harmful chemicals from the cloud are mixing with rainfall. This acid rain damages crops and trees and thre
