Apparently, we are safe neither at home nor in the business office. We use water in both places, but the research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects. These chemicals can cause potential harm through drinking and in seemingly harmless activities as cleaning one’s house. They are released(set free)from water by daily actions like water running out of tap, spraying from garden pipes，or splashing in dishwashers and washing machines. As the water is moving, these chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health.

     Does this mean we should stop bathing? No, say the scientists, but we should put all pollution into perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic. New tugs, bedding, and even clothing give off that “new smell,” which is a sure sign of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate ventilation (通风), these chemicals can build up to become health problems. Their poisonous effects are only now being slowly recognized.
     These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical smell is a wise warning. Home and office windows should be opened during good weather. Even one’s car needs to be ventilated as well while in the garage.
     We need further research to understand better other potential health dangers, too. For example, the effects of overcrowding of schools (carbon dioxide build-up), the factory work environment (an endless list of potentially dangerous substances), and even home heating and cooling (the air conditioner may be our enemies, not our friends) have only recently started to come to light. Until we understand the effects of our new technological environment better, we can only hope that “there is no place like home.”

3 . In the United States alone,over 100 million cell-phones are thrown away each year.Cell-phones are part of a growing mountain of electronic waste like computers and personal digital assistants.The electronic waste stream is increasing three times taster than traditional garbage as a whole.

Electronic devices contain valuable metals such as gold and silver.A Swiss study reported that while the weight of electronic goods represented by precious metals was relatively small in comparison to total waste,the concentration（含量）of gold and other precious metals was higher in So-called e-waste than in naturally occurring minerals.

Electronic wastes also contain many poisonous metals.Even when the machines are recycled and the harmful metals removed,the recycling process often is carried out in poor countries,in practically uncontrolled ways which allow many poisonous substances to escape into the environment.

Creating products out of raw materials creates much more waste material,up to 100 times more,than the material contained in the finished products.Consider again the cell-phone,and imagine the mines that produced those metals,the factories needed to make the box and packaging（包装）it came in.Many wastes produced in the producing process are harmful as well.

The U.S Environmental Protection Agency notes that most waste is dangerous in that"the production, distribution,and use of products-as well as management of the resulting waste-all result in greenhouse gas release." Individuals can reduce their contribution by creating less waste at the start-for instance,buying reusable products and recycling.

In many countries the concept of extended producer responsibility is being considered or has been put in place as an incentive（动机）for reducing waste.If producers are required to take back packaging they use to sell their products,would they reduce the packaging in the first place?

Governments' incentive to require producers to take responsibility for the packaging they produce is usually based on money.Why,they ask,should cities or towns be responsible for paying to deal with the bubble wrap（气泡垫）that encased your television?

From the governments' point of view,a primary goal of laws requiring extended producer responsibility is to transfer both the costs and the physical responsibility of waste management from the government and tax-payers back to the producers.

1. By mentioning the Swiss study,the author intends to tell us that         .

A．the weight of e-goods is rather small

B．natural minerals contain more precious metals

C．E-waste deserves to be made good use of

D．the percentage of precious metals is heavy in e-waste

2. The responsibility of e-waste treatment should be extended          .

A．from producers to governments

B．from governments to producers

C．from individuals to distributors

D．from distributors to governments

3. What does the passage mainly talk about?

A．The increase in e-waste.	B．The creation of e-waste.
C．The seriousness of e-waste.	D．The management of e-waste.

4 . Humankind has tried to improve its standard of living since the very beginning of civilization. Back then, as well as today, providing food and security was the basic task for a person. However, nowadays the range of required goods has expanded significantly. People feel the need for not only some primary things, such as a piece of bread and a roof over their heads, but also for various facilities and luxuries. Providing humanity with these things is connected to the use of natural resources, which requires energy. In turn, the common sources of energy we use today cause pollution, so economic growth is almost unavoidably associated with environmental damage.
Economic growth is the increase in numbers of goods and services produced over time by an economy, and it is calculated in terms of real Gross Domestic Product (GDP). Before growth is calculated, inflation (通货膨胀)is adjusted in order to take into account its mis­leading effect on the price of goods and services. Economic growth can also be explained as the increase in expected output, which results from an increase in actual output, or total de­mand.
There are certain aspects of economic growth which affect the environment. The first of these is the fact that in order to produce more goods and products, at a faster rate, the construction of large industrial plants is required. These plants produce a lot of waste, leading to the pollution of water and the atmosphere, which may cause negative long term health effects to nearby populations of animals, or people.___They___also lead to global warming.
Industrial manufacturing leads to the constantly increasing energy consumption. The traditional energy sources, which are commonly used nowadays, are considered to be the greatest polluters to the environment. There also exist so-called eco-friendly sources of energy. They are sometimes preferred but replacing the traditional sources with them also requires time, during which people have to make some sacrifices to support these undertakings.
In order to produce economically practical energy, a sometimes significant transformation of the natural site is often inevitable. This is expensive and, has harmful effects on the environment. Application of wind energy would block airflows’ natural speed which is the reason for their decrease in strength, after crossing the windmill. Consequently, the pres­sure balance that is brought about by this current will be affected, and it is important to re­member that the environment and weather conditions are directly affected by atmospheric pressure.
For these reasons, bringing about economic growth without any resulting environmental damage, whatsoever, is impossible.

5 . With alarming regularity, we read about oil tankers having accidents near land and the terrible consequences of the oil spills(泄露) on people, nature, and the environment.
Millions of dollars have been used in developing special chemicals to help dismiss the spills and to clean up the animals, beaches, and land spoiled by the oil. Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea.
Of all of today’s environmental disasters, an oil spill may actually be one of the least serious. Although oil is poisonous, it is a natural material. In the end, it breaks down naturally. There are, of course, long-term effects, but it is usually more serious in the short term.
Nature by itself works better than chemical materials, but when there is a spill we demand that governments act immediately with as much hi-tech knowledge as possible. In 1967 the tanker Torrey Canyon sank off the Scilly Isles near the coast of England and spilled 120,000 tones of oil into the ocean. If you go there today, you will find it hard to see any sign that it ever happened.
Governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage. Interestingly, the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run!
We should be thinking more about reducing our dependency on oil. Governments should be encouraging research into new technologies, such as cars run by solar power(太阳能), electricity, hydrogen, and so on. Much of this research has, in the past, been held back by the oil, gas, and coal.
If the world’s millions of cars were 10% more efficient(高效的) — and the industry could easily produce cars at least twice as efficient — we would need many fewer tankers crossing the oceans each year. If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too.
