B）连科学家们无法理解尼诺。

2. Script
M: 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 sun’s 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：每个人都在谈论环境问题 ：酸雨，温室效应，臭氧层的洞。我们应该积极地

太阳能屋顶计现在出现在 日本，美国，意大利，德国。

问：如何看待环境？

d）男女积极思考它。

3. Script


1

W: 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: That’s 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：我们几年前住在北京。它是从北方吹来的，沙子吹来保持屋子干净很困难。

男 ：这就是为什么中国政府一直在鼓励人们植树造林，在戈壁滩沙漠的边缘。现
在那些树作为风障。

问：有什么中国人被鼓励吗？

一）种树。
4. Script
M: Many old refrigerators and cars are environmental hazards because they contain
CFCs that destroy the ozone layer.
W: Yes, but government organizations are helping people to safely dispose of old
refrigerators or, in the case of cars, to upgrade their air conditioning.
Q: What are government organizations helping people to do?
A) To treat old electrical appliances safely.
M：许多旧冰箱和汽车的环境危害，因为它们含有氯氟烃破坏臭氧层。

女：是的，现在政府机构帮助人们安全地处置旧冰箱或，以汽车为例，来升级自
己的空调。

问：政府组织帮助人们做什么？

一）处理旧电器的安全。
5. Script
M: Hey. That’s an aerosol spray you’re 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 doesn’t contain CFCs. And you’d better read a little more.
Q: What does the man mean?
C) The woman should not use an aerosol spray.
男：嘿。这是一个喷雾你对你 的头发不好！等于建立一个炸弹，或充满整个公寓
快速杀死我们，不利于臭氧洞，而且我们可能死于癌症 。

W：冷静。这种喷雾不含氯氟烃。你最好多读一点。

问：这个男人是什么意思？

c）女人不应该使用喷雾。
III. Listening In
Task 1: We should have proper respect for nature!
Script
Martha: 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: Today…I 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? Um…I’d 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 it’s just littering and I hate
that. So they should be fined if they throw them on the floor on the ground.
Martha: That’s 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.

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。

3

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。所以我总是把我的垃圾扔进垃圾箱 。

Task 2: River pollution
Script

If 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:

1. What is the passage mainly about?
D) The causes of river pollution.
2. Why does the river water turn green?
A) Because nitrate and phosphate 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。

5

C）它阻止氧气进入水。

5。有什么可以温暖的河中的水带来什么？

D）缺乏氧气。
VI. Further Listening and Speaking
Task1: The environment and the development
Script
Li: Hi Professor Wang, I’m 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 today’s 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，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 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。
< br>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。

Task2: Thick cloud of pollution covering southern
Asia
Script
A 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 Earth’s 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 public health. Scientists are concerned that the pollution

will intensify during the next 30 years as the population of Asia increases to an
estimated 5,000 million people.
联合国的一项研究表示，厚厚的云层覆盖南亚的污染威 胁着上百万人的生命。科
学家说，污染可能会增加肺部疾病，导致过早死亡。云也会破坏农业和影响降雨
量。它已经影响了许多国家在亚洲南部。污染云高三公里。科学家们说，它可以
在一个星期半个 世界移动。

云是由于森林火灾，农业废弃物的燃烧，并在燃烧的燃料的车辆的大量增加，工
业和发电站。

从坏的炉具，数以百万计的污染会使问题变得更糟。许多穷人燃烧燃料如木材、
动物等炉废。

科学家说，污染云似乎冷静地阻挡阳光的海洋。他们说这可以减少多达百分之
15的 阳光到达地球表面的量。同时，云里面的热量温暖了低层的大气。

科学家说，这种组合可能 会改变亚洲冬天的降雨量。他们说的降雨量增加到东海
岸的亚洲。但它急剧下降在西北地区。报告说，这 些云可能减少在巴基斯坦西北
部，阿富汗的降雨，和高达百分之40的中国西部。

云中有害的化学物质混合与降雨。这个酸雨危害农作物、树木和威胁公众健康。
科学家担心污染将加强在 未来30年亚洲人口增长到约5000000000人。
