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.

第三部分：阅读理解（共20小题；每小题2分，满分40分）
阅读下列短文，从每题所给的四个选项A、B、C、D中选出最佳选项。
The most frightening words in the English language are,“ Our computer is down.” You hear it more and more when you are on business. The other day I was at the airport waiting for a ticket to Washington and the girl in the ticket office said,” I’m sorry, I can’t sell you a ticket .Our computer is down.”
“If your computer is down, just write me out a ticket.”
“I can’t write you out a ticket. The computer is the only one allowed to do so.”
I looked down the counter(柜台)and every passenger was just standing there drinking coffee and staring at the blank screen. Then I asked her,” What do you do?”
“We give the computer the information about your trip, and then it tells us whether you can fly or not.”
“So when it goes down, you go down with it.”
“That ‘s right, sir.”
“How long will the computer be down?” I wanted to know.
“I have no idea .Sometimes it’s down for 10 minutes , sometimes for two hours. There is no way we can find out without asking the computer , and since it’s down, it won’t answer us.”
After the girl told me they had no spare computer ,I said, “ Let’s forget the computer. What about your planes? They’re still flying aren’t they?”
“I couldn’t tell without asking the computer.”
“Maybe I could just go to the gate and ask the pilot if he’s flying to Washington.” I suggested.
“I wouldn’t know what gate to send you to .Even if the pilot was going to Washington, he couldn’t take you if you didn’t have a ticket.”
“Is there any other airline flying to Washington within the next few hours?”
“I wouldn’t know,” she said, pointing at the dark screen.” Only ‘IT’ knows . ’IT’ can’t tell me.”
By this time there were quite a few people standing in lines .The words soon spread to other travelers that the computer was down Some people went, some people started to cry and still others kicked(踢) their luggage.

Some years ago industries had more freedom than they have now，and they did not need to be as careful as they must today. They did not need to worry a lot about the safety of the new products that they developed. They did not have to pay much attention to the health and safety of the people who worked for them. Often new products were dangerous for the people who used them; often conditions in the work place had very bad effects on the health of the workers.
Of course sometimes there were real disasters which attracted the attention of governments and which showed the need for changes. Also scientists who were doing research into the health of workers sometimes produced information which governments could not ignore. At such times, there were inquiries into the causes of the disasters or the problems. New safety rules were often introduced as a result of these inquiries; however, the new rules came too late to protect the people who died or who became seriously ill.
Today many governments have special departments which protect customers and workers. In the U.S., for example, there is a department which tests new airplanes and gives warnings about possible problems. It also makes the rules that aircraft producers must follow. Another department controls the foods and drugs that companies sell. A third department looks at the places where people work, and then reports any companies that are breaking the laws which protect the health and safety of workers. Of course, new government departments and new laws cannot prevent every accident or illness, but they are having some good results. Our work places are safer and cleaner than before. The planes and cars which we use for travel are better. Producers are thinking more about the safety and health of the people who buy and use their products.

A California family drives a car that could help protect the environment. When Jon and Sandy go to the store or to their daughters’ soccer games, they drive in high-tech style. They drive a $1 million, fuel-cell-powered car. It may be the world’s most expensive car and one of the most environmentally friendly cars. The FCX is the first fuel-cell-powered car to be used by a family anywhere in the world. The FCX uses hydrogen and oxygen for fuel. Car makers have been working to develop vehicles that are better for the environment. They are developing cars that use fuel other than gasoline. And then what is fuel cell technology? Fuel cell technology works by changing the chemicals hydrogen and oxygen into water. This process produces electricity, and water vapor which comes out of the exhaust pipe. Most cars release dangerous gases such as carbon monoxide and carbon dioxide. Many scientists say these gases are major contributors to global warming. “The FCX is driven just like any other vehicle on the road, but without the gases which pollute the environment,” scientists say. Fuel cell technology has been around since the 1800s, but scientists have yet been to perfect it. They say it may take years before the technology is ready for widespread use. Another earth-friendly car is already on the market. Hybrid cars use both gasoline and an electric motor. They are becoming more popular with customers because they cut pollution and improve fuel efficiency.
46. Which of the following about the FCX is not true?
A. It may be the most expensive car in the world.
B. It is one of the most environmentally friendly cars.
C. It releases dangerous gases to pollute the air.

47. According to the passage, what is the major cause for global warming?
A. Gases from FCX. B. Water vapor from cars.

48. From the passage, we know that fuel cell technology ______.
A. works by water B. has a history for over two hundred years
C. works by electricity D. has been widely used since the 1800s
49. We can infer from the passage that ______.
A. future cars will be environmentally friendly
B. there will be no gasoline for cars
C. people can’t afford to buy cars in the future
D. global warming has been stopped
50. Hybrid cars are popular because ______.
