ScriptM: Everyone is talking about environmental problem: acid rain, greenhouse effect, holes in the ozone layer. We should think positively. What can we do to improve things?W: I agree. We could do a lot more to harness the suns energy for heating and lighting in our homes. Millions of solar roofs are now emerging in Japan, the U.S., Italy, and Germany.Q: How do the man and the woman view the environment?D) Both the man and woman think positively about it.M：每個(gè)人都在談?wù)摥h(huán)境問題：酸雨，溫室效應(yīng)，臭氧層的洞。我們應(yīng)該積極地思考。我們能做什么來提高呢？W：我同意。我們可以做更多的事來利用太陽的能量加熱和在我們的家庭照明。太陽能屋頂計(jì)現(xiàn)在出現(xiàn)在日本，美國，意大利，德國。問：如何看待環(huán)境？d）男女積極思考它。3. ScriptW: We lived in Beijing some years ago. It was always difficult to keep the house clean with the wind from the north blowing sand from the desert.M: Thats why the Chinese government has been encouraging people to plant trees along the edges of the Gobi Desert. Now those trees act as wind barriers.Q: What have the Chinese people been encouraged to do?A) To grow trees.W：我們幾年前住在北京。它是從北方吹來的，沙子吹來保持屋子干凈很困難。男：這就是為什么中國政府一直在鼓勵人們植樹造林，在戈壁灘沙漠的邊緣。現(xiàn)在那些樹作為風(fēng)障。問：有什么中國人被鼓勵嗎？一）種樹。4.

ScriptM: Hey. Thats an aerosol spray youre using on your hair! Build a bomb or set fire to the apartment to kill us quickly instead of making holes in the ozone, so we die of cancer. W: Cool it. This spray doesnt contain CFCs. And youd better read a little more. Q: What does the man mean?C) The woman should not use an aerosol spray.男：嘿。這是一個(gè)噴霧你對你的頭發(fā)不好！等于建立一個(gè)炸彈，或充滿整個(gè)公寓快速殺死我們，不利于臭氧洞，而且我們可能死于癌癥。W：冷靜。這種噴霧不含氯氟烴。你最好多讀一點(diǎn)。問：這個(gè)男人是什么意思？c）女人不應(yīng)該使用噴霧。III. Listening 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 problem, 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 think 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 for 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 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.瑪莎：你認(rèn)為在你的文化中人們尊重大自然？艾德：我是這么認(rèn)為的。嗯現(xiàn)在比以前更多?，斏耗阏J(rèn)為什么是當(dāng)今世界最嚴(yán)重的環(huán)境問題？艾德：今天我想破壞臭氧層，是一個(gè)大問題，一個(gè)問題是在大城市的污染等等。瑪莎：你怎么了解環(huán)境問題？艾德：嗯通過學(xué)校。很多俱樂部促進(jìn)環(huán)境安全，和一些電視節(jié)目，太。他們談?wù)摥h(huán)境安全的東西?，斏耗阏J(rèn)為學(xué)生應(yīng)該在學(xué)校學(xué)會更多關(guān)于環(huán)境的問題嗎？艾德：我是這么認(rèn)為的。所以，當(dāng)他們長大后，他們可以更清楚地了解所有的問題，要，并防止更多的問題。瑪莎：如果你能創(chuàng)造新的法律幫助環(huán)境，它會是什么？艾德：對環(huán)境的新法律？嗯我可能會說，當(dāng)人們?nèi)拥舻臒燁^，他們不得不把它們?nèi)拥嚼埃浑S便亂扔垃圾，我憎恨這種行為。所以他們應(yīng)該罰款如果他們?nèi)釉诘匕迳稀，斏耗鞘莻€(gè)好主意。那么個(gè)人的事怎么來幫助保護(hù)環(huán)境呢？艾德：我非常反對亂扔垃圾。我從不亂扔垃圾。如果我看到有人亂扔垃圾，我真的生氣了。所以我總是把我的垃圾扔進(jìn)垃圾箱。Key:(1) 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 possible 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. 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 cyanide, 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 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 discharging 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.如果你看到死魚漂浮在河上或發(fā)現(xiàn)水變色發(fā)臭，你知道那條河被污染了，和有四個(gè)主要的它可能的原因。第一，施肥。如果大量施肥或農(nóng)場廢物排入河中的水，大大增加的硝酸鹽和磷酸鹽的濃度。藻類利用這些物質(zhì)的快速增長，將水綠色。這種大規(guī)模的藻類生長導(dǎo)致污染。當(dāng)藻類死亡，他們打破了細(xì)菌的行動，并迅速繁殖，耗盡水中的氧氣，導(dǎo)致魚類死亡。第二，工業(yè)廢水。工廠排放的化學(xué)廢料排入河流有時(shí)。等污染物的例子包括氰化物，鉛，銅，汞。這些高濃度物質(zhì)進(jìn)入河中可能立即殺死魚類和其他動物。有時(shí)，污染物進(jìn)入食物鏈積累到有毒水平，最終殺死魚類和其他動物。第三，石油污染。如果油進(jìn)入流動緩慢的河流，它形成了一個(gè)彩虹色膜的整個(gè)表面，防止氧進(jìn)入水。第四，溫水。行業(yè)經(jīng)常采用水冷卻的過程，有時(shí)排出大量的溫水回到河流。較高的水的溫度降低溶解氧水平，使生命的水平衡。Question and key:1.

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 relationship 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 pollution, 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, growing 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 environment 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 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 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，從大學(xué)報(bào)的記者。工作人員和這里的學(xué)生越來越多，在環(huán)境與經(jīng)濟(jì)發(fā)展之間的關(guān)系更感興趣。你認(rèn)為什么是目前最嚴(yán)重的環(huán)境問題？我們應(yīng)該采取什么措施來改善環(huán)境，在發(fā)展經(jīng)濟(jì)的同時(shí)？王：有很多環(huán)境問題：空氣污染，水污染，沙漠化，過度捕撈，自然棲息地的破壞，酸雨，野生動植物的過度消費(fèi)，而躺在這些問題中，我認(rèn)為，是經(jīng)濟(jì)增長和環(huán)境保護(hù)之間的矛盾。聯(lián)合國1992地球峰會以來，越來越多的人和政府都采取了“可持續(xù)發(fā)展的新理念”。這意味著今天的經(jīng)濟(jì)增長不應(yīng)消滅的資源和未來的選擇。規(guī)劃和發(fā)展應(yīng)確保的不僅是經(jīng)濟(jì)增長，但同時(shí)社會進(jìn)步和環(huán)境健康。換句話說，一些經(jīng)濟(jì)行為必須受到制約。將可持續(xù)發(fā)展原則逐步納入政府規(guī)劃，資源管理和經(jīng)濟(jì)政策是最重要的一步，中國可以解決環(huán)境問題。中國已采取了一些重大措施來減少對環(huán)境的破壞。例如，1998的大洪水后，政府禁止砍伐長江上游為了保護(hù)森林和減少洪水風(fēng)險(xiǎn)。然而，環(huán)境與發(fā)展之間的基本矛盾依然存在。大量的工作是要實(shí)現(xiàn)經(jīng)濟(jì)增長與環(huán)境之間的平衡的目的了。Key:(1) water pollution overconsumption economic growth resourcessocial advancement restricted government planning economic policyremarkable steps balance Task2: Thick cloud of pollution covering southern AsiaScriptA United Nations study says that a thick 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 cloud 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 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 same time, heat inside the cloud warms the lower parts of the atmosphere.Scientists 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 threatens publ
