A promising approach     1     solving air pollution can be found in Beijing, after China declared a "war against pollution" in 2014. A seven-meter-high "Smog Free Tower" opened in Beijing's 751 D Park in September 2016. It is a huge, outdoor air purifier. Airborne particles (颗粒) are sucked into the tower     2     they receive a positive charge (正电荷). The particles are then caught by a negatively negative charged dust-removal plate and finally clean air     3     (blow) out of the other end.

As for what to do with the collected PM waste, The designer has currently set up a business to make jewelers out of the waste. If collected on a big scale, the designer believes     4     could even be used as a building material.

4 . The world itself is becoming much smaller by using modern traffic and modern communication means. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.

Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true.

Man is now slowly polluting the whole world. Air pollution is still the most serious. It’s bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.

Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air. Pollution by SO 2 is now the most dangerous kind of air pollution. It is caused by heavy traffic. We are sure that if there are fewer people driving, there will be less air pollution.

The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must take care of the rise in pollution at the same time.

5 . The idea of turning recycled plastic bottles into clothing is not new. During the last five years, a large number of clothing companies, businesses and environmental organizations have started turning plastics into fabric to deal with plastic pollution. But there’s a problem with this method. Research now shows that microfibers could be the biggest source of plastic in the sea.

Dr. Mark Browne in Santa Barbara, California, has been studying plastic pollution and microfibers for 10 years now. He explains that every time synthetic clothes go into a washing machine, a large number of plastic fibers fall off. Most washing machines can’t collect these microfibers. So every time the water gets out of a washing machine, microfibers are entering the sewers and finally end up in the sea.

In 2011, Browne wrote a paper stating that a single piece of synthetic(合成的) clothing can produce more than 1, 900 fibers per wash. Browne collected samples from seawater and freshwater sites around the world, and used a special way to examine each sample. He discovered that every single water sample contained microfibers.

This is bad news for a number of reasons. Plastic can cause harm to sea life when eaten. Studies have also shown that plastic can absorb other pollutants.

Based on this evidence, it may seem surprising that companies and organizations have chosen to turn plastic waste into clothing as an environmental “solution.” Even though the science has been around for a while, Browne explains that he's had a difficult time getting companies to listen. When he asked well-known clothing companies to support Benign by Design-his research project that seeks to get clothes that have a bad effect on humans and the environment out of the market, Browne didn’t get a satisfying answer. Only one women’s clothing company, Eileen Fisher, offered Browne funding.

6 . There are 5.25 trillion pieces of plastic trash in the world’s oceans, and each year, 8 million tons of plastic are added to the figure. Though the oceans seem vast enough to stomach a lot of plastic, the level of waste is starting to reach a crisis point: According to a new report by the Ocean Conservancy, by 2025, the ocean could contain one ton of plastic for every three tons of finfish.

All these floating bits of plastic not only disrupt marine ecosystems, but they also poison the global supply of seafood. “It’s reaching crisis proportions,” says Andreas Merkl, CEO of the Ocean Conservancy. “Plastic breaks down into small pieces that look like plankton and is eaten by everyone from plankton to whales.” Plastic acts as a pollution sponge in the ocean, so when wildlife swallow pieces, the plastic might as well be a poison pill.

The new report calls for a focus on improving waste management systems in a handful of developing countries that are most responsible for the plastic leakage into the ocean. China, Indonesia, the Philippines, Thailand and Vietnam contribute more than half of the oceans’ plastic since their waste facilities hasn’t kept up with rapid industrialization.

On average, only about 40% of waste in these countries is actually picked up for disposal. But it’s not just uncollected waste floating around-though that is three-fourths of the problem. The other quarter of the oceans’ plastic came from post-collection activities. Even when a waste management company picks up waste to landfill it, poorly equipped landfills or illegal dumping mean that trash still ends up in the ocean.

But how can countries stop the leakage of waste into the ocean? The Ocean Conservancy report suggests five “levers”: waste collection services, closing the leakage points within the collection system, gasification and burning of waste, and recycling facilities. The average waste ends up as litter. Just by expanding collection systems and plugging up their leakage points, the report says plastics leakage could by cut by 50% by 2020.

It’s not just an environmentalist’s daydream. Coca-Cola and Dow Chemical, along with some other multinational companies have joined forces with Ocean Conservancy to fight ocean pollution. “We’re committed to working toward a future of a plastic-free ocean. Companies don’t make plastic with the intent of it ending up in the ocean, and we acknowledge the strong role industry must play in order to help eliminate ocean plastic waste by 2035.” Says Dow Packaging and Speciality Plastics’ global sustainability director in a press release.

Merkl emphasized that the countries can’t recycle their way out of the problem. Only about 20% of the waste is valuable enough to be worth recycling: the rest, needs to be sent to sanitary landfills or waste-to-energy plants. “You have to concentrate on the fundamentals of waste management,” he says. And while building landfills and incinerators(焚化炉)across these developing countries might not be pretty, it’s far more environmentally friendly than letting waste slide into the world’s oceans.

7 . 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.

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.
