题目内容

Waste can be seen everywhere in the school. Some students ask for more food than they can eat and others often forget to turn off the lights when they leave the classroom. They say they can afford these things. But I don't agree with them.
　　Waste can bring a lot of problems. Although China is rich in some resources（资源）， we are short of（缺乏） others， for example， fresh water（淡水）。 It is reported that we will have no coal（煤） or oil to use in 100 years. So if we go on wasting our resources， what can we use in the future and where can we move？ Think about it.I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.
　　In our everyday life，we can do many things to prevent waste from happening，for example，turn off the water taps（水龙头） when we finish washing， turn off the lights when we leave the classroom，try not to order more food than we need，and so on. Little by little，everything will be changed. Waste can be stopped one day，if we do our best.
　26. From the passage we know that some students often _______ in the school.
　A. eat too much                B. don't work hard
　C. waste things                D. throw rubbish everywhere
　27. Which is not mentioned in this passage？
　A. Fresh water                 B. Forest.
　C. Oil.                        D. Coal.
　28. What may happen in 100 years？
　A. We may still have enough oil.        B. We may still have enough coal.
　C. We may have a little oil.            D. We may have no coal or oil to use.

Besides giving off gases and dusts into the air, humans produce waste that is poured on the environment. Often, this waste produced by major industries and people is harmful to both nature and human life.

One of the main causes of the large amount of dangerous waste is that people do not realize how large a problem it is. Because it can be simply removed and sent to a landfill（废渣填埋场）, the problem is often believed to end there. In addition, industries have often shown an unwillingness to find ways to deal with dangerous waste because of the related expenses. Many industries and governments build simple landfills to store waste, and often just pour waste chemicals into nearby bodies of water. Often, chemicals used for industrial production cause dangerous forms of waste. The amount of these chemicals has increased greatly in the past, but it is often difficult and expensive to get rid of these chemicals or to store them in a way safe to human life and the environment.

Every year, major health problems result from dangerous waste. Sadly, it is often only after someone has died or become seriously ill that governments will take measures to reduce levels of harmful waste.

Some governments have realized how serious the dangerous waste problem is and are now trying to settle this problem. They are also trying to limit the amount of waste industries are allowed to produce.

Not only governments but ordinary people as well must work together to solve the problem. They can choose not to buy those products which require the production of dangerous waste, and produce less harmful waste themselves. Many scientists think that waste production can be cut. The waste can be reduced by at least one third using existing technologies and methods.

American like to visit the national parks. In 1996, over 250,000,000 people visited areas run by the National Park Service. Experts predict that by 2010, 500,000,000 people per year will visit the parks. As a result, people are trying to think of ways to protect the parks from the crowds.

The crowding of the parks has caused several problems. One is that there is not enough space for all of the people who want to use the parks. To cope with this problem, national parks may require reservations months in advance for some spots. The Park Service may also raise entrance fees at these places.

Another problem caused by increased park use is pollution. Some garbage and waste can be cleaned up, and the cleanup can be paid for by increased entrance fees. To cut down on noise pollution and air pollution, officials may decrease the number of cars allowed in parks. If this happens, people may use buses to travel around the parks. Officials may also limit the use of jet-skis, snowmobiles (摩托雪橇), motorboats, and sightseeing helicopters and planes.

The parks are also threatened by development that is going on around them. For example, around Yellow Stone Park, many motels (汽车旅馆), golf courses, resorts, and other tourist attractions have been built. Some of these developments affect areas that are used by animals. People will have to learn to agree about ways to protect the parks. If they do not, there will soon be no reason to visit these national treasures.

By 2010, the number of visitors will rise by ______ per year.

A. 250 million B. 500 million C. 2.5 billion D. 5 billion

If you want to visit the national parks, you may have to _____ in the future.

A. pay less than before B. stay there for months

C. book the ticket before months D. fill in a form to apply for the ticket

Entrance fees may be increased _______.

A. just for the benefit of the National Park Service

B. either to limit the number of visitors or to pay for the cleaner

C. not only to protect the animals but to reduce the noise pollution

D. merely for the development of the national parks

What does the underlined sentence in the passage mean?

A. People are not supposed to visit the national parks for fear that they will harm the animals.

B. Only if more man-made tourist attractions are built will more people visit the parks.

C. It is reasonable to keep the balance between the development of the parks and the reserve.

D. People will not visit the national parks since there are no golf courses and resorts.

What can be inferred from the passage?

A. High fees may probably keep some people out of parks.

B. Helicopters and planes will not be used in parks any longer.

C. The bus will become the only toot in parks with the purpose of pollution reduction.

D. The National Park Service welcomes as many visitors as possible.

Waste to Energy—JUST BURN IT!

WHY BURN WASTE?

Waste-to-energy plants generate (产生) enough electricity to supply 2.4 million households in the US. But, providing electricity is not the major advantage of waste-to-energy plants. In fact, it costs more to generate electricity at a waste-to-energy plant than it does at a coal, nuclear, or hydropower plant.

The major advantage of burning waste is that it considerably reduces the amount of trash going to landfills. The average American produces more than 1,600 pounds of waste a year. If all this waste were landfilled, it would take more than two cubic yards of landfill space. That’s the volume of a box three feet long, three feet wide, and six feet high. If that waste were burned, the ashes would fit into a box three feet long, three feet wide, but only nine inches high!

Some communities in the Northeast may be running out of land for new landfills. And, since most people don’t want landfills in their backyards, it has become more difficult to obtain permits to build new landfills. Taking the country as a whole, the United States has plenty of open space, of course, but it is expensive to transport garbage a long distance to put it into a landfill.

TO BURN OR NOT TO BURN?

Some people are concerned that burning garbage may harm the environment. Like coal plants, waste-to-energy plants produce air pollution when the fuel is burned to produce steam or electricity. Burning garbage releases the chemicals and substances found in the waste. Some chemicals can be a threat to people, the environment, or both, if they are not properly controlled.

Some critics of waste-to-energy plants are afraid that burning waste will hamper (妨碍，阻碍) recycling programs. If everyone sends their trash to a waste-to-energy plant, they say, there will be little motive to recycle. Several states have considered or are considering banning waste-to-energy plants unless recycling programs are in place. Massachusetts, New Jersey, and New York City have delayed new waste-to-energy plants, hoping to increase the level of recycling first.

So, what’s the real story? Can recycling and burning waste coexist? At first glance, recycling and waste-to-energy seem to be at odds (不一致), but they can actually complement (弥补) each other. That’s because it makes good sense to recycle some materials, and better sense to burn others.

Let’s look at aluminum, for example. Aluminum mineral is so expensive to mine that recycling aluminum more than pays for itself. Burning it produces no energy. So clearly, aluminum is valuable to recycle and not useful to burn.

Paper, on the other hand, can either be burned or recycled—it all depends on the price the used paper will bring.

Plastics are another matter. Because plastics are made from petroleum and natural gas, they are excellent sources of energy for waste-to-energy plants. This is especially true since plastics are not as easy to recycle as steel, aluminum, or paper. Plastics almost always have to be hand sorted and making a product from recycled plastics may cost more than making it from new materials.

To burn or not to burn is not really the question. We should use both recycling and waste-to-energy as alternatives to landfilling.
