Pollution and Ecocrisis　　The problem of pollution is also of great social concern. Continued population increase, accompanied by a rise in the level of living standards, not only threatens to exhaust American resources but pollutes the environment to such an extent that production in the thickly settled area is impossible without damaging the health of the local residents.　　Smog, once an urban annoyance, is now recognized as a health risk, and the automobile has been pinpointed as the principal culprit. Heavy industries have been blamed for river, soil, air, noise and visual pollutions. DDT and other chemical remedies have been doing more ecological harm than the good that they may have brought along.　　Several decades ago, Americans dumped raw sewage into rivers and many industrial plants are now still dumping chemical pollutants into lakes, rivers and oceans. Oceans used to be and are still being considered to be a reserve of seafood. Today, after the oceans have become the home of all pollutants, this use of the oceans is being reduced at an alarming rate.　　The worst pollution threat is concentrated in and near large cities. There the people-made pollutants increasingly surpass the ability of air and water to dilute (冲淡；稀释) the contaminants (污染物) to safe levels. The natural ecological cycle depends on plants, which absorb some pollutants and release oxygen to the air. But near large cities, natural vegetation becomes scarce, and introduced trees, ornamental shrubs and gardens are far from adequate in absorbing motor vehicle and industrial air pollutants. Finally, some pollutants, most notably atomic waste, may continue to contaminate air, land, and water for thousands of years. Therefore, ecocrisis—ecocatastrophe or ecocide—has been for some time one of the major concerns of not only the ecoactivists and environmentalists, but of many scientists of other fields and the government authorities of many countries as well.　　Last but not least, there is the question of whether the people will eventually be able to solve all these problems. The American continent is a wealthy land inhabited by many able and well-　　educated people. There today, people have originated a life-style which is known to the world as being characteristic of a society of consumption—a life-style based on the prodigal (挥霍浪费的) use of material goods. They are using up many times their share of the earth’s resources at a rate unparalleled in history. And I am sorry to say that this life-style of American has been copied by the people of many developed countries, leading to the greatest problem of the modem world as a whole. So I must ask: Are the Americans apt enough to cooperate with other peoples to prevent over-population, resource exhaustion, the catastrophe of pollution and the wanton waste of wealth — problems which are basic to the solution of many outstanding economic, social and political problems? Only time will tell.
参考答案和解析
正确答案： 【参考译文】
污染和生态危机 污染问题也受到了社会的极大关注。生活水平在提高,人口在持续增长,这不仅预示着美国资源面临枯竭,而且污染环境到了极严重的地步:人口密集区的工业生产与当地居民的健康已成为不可调和的矛盾。
烟雾,原先不过是居民的一件烦恼事,现在被公认为危害健康的大敌。汽车已被指控为损害健康的罪魁祸首。重工业因污染河流、土壤、空气、产生噪音和妨碍人们的视觉而备受指责。DDT及其他化学药剂对生态的影响是弊大于利。
几十年前,美国人把未经处理的污水倒入河流,而许多工厂如今仍在把化学污染物倒入湖泊、江河和海洋。人们一向认为海洋是海产品的宝库。今天,海洋已成为一切污染物的集中地之后,海产品正以惊人速度缩减。
大城市及其周边是污染最严重的地方。在那里,人为污染物的扩散超过了空气和水将污染物分解稀释到安全水平的能力。自然界生态循环依赖于植物;植物吸收一些污染物,把氧气释放到空气中。但邻近大城市的地区,天然植被日见稀少,而移植的树木、观赏灌木及花园又远不足以吸收机动车辆和工业带来的空气污染物。最后,有些污染物,尤其是臭名昭彰的原子能废料,可能会继续污染空气、土地和水达几千年之久。因此,生态危机——也称为生态灾难或生态灭绝——一段时期以来不仅是生态活动家和环保主义者关注的主要问题,而且引起了其他领域许多科学家和许多国家的政府当局的重视。
最后,人们最终是否能解决所有这些问题? 美国大陆是一块富饶的土地,居住着许多能干的、受过良好教育的人。今天,在那里人们开创了一种以消费社会为特色而闻名全球的生活方式,即一种挥霍物质财富为基础的生活方式。美国人正以史无前例的速度耗费着超过他们份内不知多少倍的地球资源。我遗憾地说,美国人的这种生活方式,已被许多发达国家的人民所仿效,导致了当前整个世界的最严重的问题。
因此我不得不问:
美国人是否善于与别国人民合作来防止人口过剩、资源枯竭、污染灾难和恣意浪费人类财富的行为? 这一系列问题正是解决许多突出的经济、社会和政治问题的基础。我们将拭目以待。

Man has been using the earth’s 27 more and more rapidly over the years.Some of them are almost gone.Now many people believe that man’s greatest 28 is how to control the growth of this population.The materials in the world will not support the human population in time to come if the present rate of increase continues.29 there is over crowding in the cities and hunger in some countries.Can man’s rate of increase continue?

Preserve the Environment

Throughout history man has changed his physical environment in order to improve his way of life.
With the tools of technology he has altered many physical features of the earth.He has transformed
woodlands into farmland,and made lakes and reservoirs out of rivers for irrigation purposes or hydroelectric
power. Man has also modified the face of the earth by draining marshes and cutting through mountains to
build roads and railways.
However,man's changes to the physical environment have not always had beneficial results.Today,
pollution of the air and water is an increasing danger to the health of the planet.Each day thousands of tons
of gases come out of the exhausts of motor vehicles;smoke from factories pollutes the air of industrialized areas
and the surrounding areas of countryside.The air in cities is becoming increasingly unhealthy.
The pollution of water is equally harmful.In the sea,pollution from oil is increasing and is killing enor-
mous numbers of algae（水藻）,fish and birds.The whole ecological balance of the sea is being changed.
The same problem exists in rivers.Industrial wastes have already made many rivers lifeless.
Conservationists believe that it is now necessary for man to limit the growth of technology in order to sur-
vive on earth.

According to the passage,pollution of the air and water is caused by__________.
A:thousands of tons of gases coming out of the exhausts of motor vehicles
B:the changes of the environment that technology has brought to man
C:the increasing amount of oil that has been produced
D:industrial wastes discharged into rivers

第7题：

People all over the world today are beginning to hear and learn more and more about the problem of pollution.Pollution is caused either by man s release of completely new and often artificial substances into the environment, or by releasing greatly increased amounts of a natural substance, such as oil tankers into the sea

Whatever it' s underlying reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments would make more efforts In the home there is an obvious need to control litter and waste Food comes wrapped up three or four times in packages that all have to be disposed of: drinks are increa singly sold in bottles or tins which cannot be reused.This not only causes a litter problem, but also is a great waste of resources, in term of glass metals and paper.Advertising has helped this process by persuading many of us not only to buy things we neither want nor need, but also to throw away much of what we do buy Pollution and waste combine to be a problem everyone can help to solve by cutting out unnecessary buying, excess consumption and careless disposal of the products we use in our daily lives.

21.The main cause of pollution is

A the release of artificial or natural substances into the envIronment

B.the production of new industrial goods

C.increased amounts of a natural substance

22.Much of the pol lut ion could be controlled if only

A.people would pay more attention to the problem

B.governments would take effective measures

C.all sides concerned would make more efforts

23.Food packages, bottles and tins for drinks can cause

A.air and water pollution

Passage Three

The whole industrial process which makes many of the goods and machines we need

and use in our daily lives, is bound to create a number of waste products which

upset the environmental balance or the ecological(生态的)balance as it is known. Many of these waste products can be prevented or disposed(处理) of sensibly, but clearly while more and more new goods are produced and made complex, there will

be new, dangerous wastes to be disposed of, for example, the waste products from nuclear power

stations. Many people therefore see pollution as only part of a larger and more complex problem, that is,

the whole process of industrial production and consumption of goods. Others see the problem mainly in

connection with agriculture, where new methods are helping farmers grow more and more on their

land to feed our everincreasing population. However, the land itself is gradually

becoming worn out as it is being used, in some cases, too heavily, and artificial

fertilizers(人造肥料) cannot bring back the balance.

Whatever is underlying(潜在的)reasons, there is no doubt that much of the pollution caused could be controlled if only companies,

individuals and governments would make more efforts. In the home there is an obvious need to control litter(杂乱的废物)and waste. Food is wrapped up three or four times in packages that all have to be disposed of; drinks are

increasingly sold in bottles or tins which cannot be reused. This not only causes a litter problem, but also is

a great waste of resources, in terms of glass, metals and paper. Advertising has helped this process by

persuading many of us to buy things we don't want to buy. Pollution and waste continue to be a problem

everyone can help to solve by cutting out unnecessary buying, excess consumption and careless disposal of

the products we use in our daily lives.

44. The main cause of pollution is______.

A. the production of new industrial goods

B. increased amounts of unnatural substance

C. our ever-increasing population

D. the release of artificial substances into the environment
