阅读下列三篇短文，从每题所给的四个选现（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。
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.
1. By 2010, the number of visitors will rise by ______ per year.
A. 250 million              B. 500 million              C. 2.5 billion         D. 5 billion
2. 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
3. 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
4. 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.
5. 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.

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.

A. do not produce harmful waste in their daily life

74.What troubles industries most in dealing with the dangerous waste problem?

A. How to get government support.

B. How to increase their production.

C. How to store harmful waste.

D. How to cut down the related costs.

75. What can be inferred from the passage?

A. The polluting industries are not allowed to sell their products.

B. Present technologies have settled the harmful waste problem.

C. Everyone should obey the government rules for the problem.

D. To solve the problem requires the efforts of the whole society.

How could we have thought so wrongly of as banana peel that it always hits the garbage? Utility of anything seems to be in the eyes of the beholder. The banana peel hasn't been an exception.
What most of us looked at as waste was converted to a thing of utility by Prithwis Mukhopadlyay, a 14-year-old prodigy. This Bengali boy, nourished in the US, Lake Junior High in Woodbury, Minnesota, has come up with an idea to convert banana peels to biogas.(生物气).
It's well known that almost any organic waste can be converted to biogas. But why biogas from banana peel has hit the news is because it produced five times as much biogas as manure(粪), a commonly used source for producing biogas, in the experiments Prithwis conducted.  
He filled two airtight containers, one with manure and the other with banana peels. Then he mixed each content with water and connected them to empty jars via pipes to collect the gas produced. He placed a heater next to each jar and measured the gas collected for 60 days. His studies proved that banana peels produced five times more biogas than manure.
This project titled 'Comparison analysis: Eco-friendly source of energy for the future,' earned him a spot in Discovery Channel Young Scientist Challenge. This weekend, the young whiz is to showcase his research work along with 40 other finalists at Washington. "Initially, I thought of doing a project that would reduce global warming. Things changed after I visited a biogas plant in a village in India during my summer vacations. It was an amazing experience," Prithwis says.
【小题1】Why could Prithwis's finding receive the attention of the media?
