San Francisco, a leader in urban recycling, is preparing to turn dog waste into energy.
Norcal Waste System Inc., the city’s largest garbage company, plans to test collection carts(回收车)and collection bags in a city-center park which is popular with dog walkers.
A city study found that almost 4 percent of all the garbage picked up at San Francisco homes was from animal waste, Norcal Waste spokesman Robert Reid said. San Francisco has about 120,000 dogs.
“The city asked us to start a program to recycle dog waste in order to cut back adding more waste in landfills(废渣埋填池) “,Reid said.
Dog waste will be poured into a methane digester(沼气池),and the methane it gives off will be collected and burned to make electricity or to heat homes.
“Dogs and cats in the United States produce about 10 million tons of waste a year,” Will Brinton, an environmental scientist said.
“As much as we love them, our pets leave a lot of fertilizer behind them in yards and on the street but that can be a major source of contamination of groundwater,” Brinton said.
European cities such as Zurich, Frankfurt, Munich and Vienna are starting biology programs to turn waste into gas ,he said.
San Francisco runs a great program to recycle bottles, cars, paper and other rubbish and now two-thirds of its garbage needn’t be carried to landfills .The city’s goal is a 75 percent drop by 2010 and zero new waste in landfills by 2020.
San Francisco will plan to use dog waste for making __________.
A. fertilizer B. gas C. electricity D. methane
What does the underlined word “ contamination” mean?
A. Increase B. Reduction C. Flow D. Pollution

阅读下面短文，掌握其大意，然后从文后所给各题的四个选项中，选出可以填入空白处的最佳选项。
Millions of people die of hunger in Southern Africa every year, but when Zambia was offered thousands of tons of free maize by the US, the government politely said no.
“We don’t know whether the food is safe,” said Zambia’s Commerce, Trade and Industry Minister Dipak Patel.
His worries are shared by countries around the world that are in two minds about America’s genetically modified (GM) crops. Just last week, EU member nations were discussing whether or not to import GM sweet corn from the US.
Ever since people started farming, they have tried to crossbreed (杂交) plants to make them stronger or better tasting. At one time, only related plants could be crossed with each other.
But when GM techniques were developed in the 1970s, scientists were able to put a single gene from a living creature into an unrelated creature.
This means they can make crops more productive and resistant to disease by adding genes from other species. They can also create food with special characteristics, such as “golden rice”, which is enriched with vitamin A. But many people believe GM foods are a health risk.
“If left to me, I would certainly not eat GM foods,” said Scottish scientist Arpad Pusztai. “We are putting new things into food which haven’t been eaten before. The effects on the immune system are not easy to predict.”
At the moment, the official argument is that GM foods “are not likely to present risks for human health”. But there are still many questions to be answered as the foods are produced in different ways.
Some experts believe the genetic material added to plants can transfer to humans and give damage to our bodies. Further harm could be caused by the genes from GM plants crossbreeding with naturally produced crops.
1. We learn from the passage __________.
A. people have discovered that GM foods will do harm to human health
B. millions of Zambia people die of eating too much GM foods
C. people are still not sure if GM foods will do harm to human health
D. genetic material added to plants will damage our bodies sooner or later
2. What does “in two minds” in the third paragraph mean?
A. Unsure. B. Worried. C. Likely. D. Careless.
3. Which of the following statements is NOT true about GM foods?
A. It is produced from plants added genes from other species.
B. GM foods can have special characteristics.
C. GM foods will affect people’s immune system.
D. GM foods have been produced since 1970s.
4. What’s the author’s attitude?
A. Supportive. B. Neutral. C. Doubtful. D. Critical.

第一节 阅读理解（共15小题，每小题2分，满分30分）
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.
41. By 2010, the number of visitors will rise by ______ per year.
A. 250 million B. 500 million C. 2.5 billion D. 5 billion
42. 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
43. 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
44. 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.
45. 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.
