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.
【语篇概述】本文是一篇科普说明文。主要介绍了使汽车更加环保的燃料电池技术。
1. Which of the following about the FCX is not true?
A. It lets out dangerous gases to pollute the air.
B. It may be the most expensive car in the world.
C. It is one of the most environmentally friendly cars.
D. It uses hydrogen and oxygen for fuel other than gasoline.
【解析】选A。推理判断题。根据第二段中的“The FCX is driven just like any other vehicle on the road, but without the gases which pollute the environment”可知, FCX和道路上的任何其他车辆一样, 但没有污染环境的气体。因此推断FCX不会排放有害气体污染空气, 故A项正确。
2. According to the passage, what is the major cause for global warming?
A. gases from FCX. B. gases from cars.
C. hydrogen and oxygen. D. water vapor from cars.
【解析】选B。细节理解题。根据第二段中的“Most cars release dangerous gases such as carbon monoxide and carbon dioxide. Many scientists say these gases are major contributors to global warming. ”可知, 科学家认为汽车所排放的比如一氧化碳和二氧化碳这样的气体是全球变暖的主要原因, 故B项正确。
3. From the passage, we know that fuel cell technology ________.
A. works by water
B. works by electricity
C. has been widely used since the 1800s
D. has a history for over two hundred years
【解析】选D。细节理解题。根据第二段中的“Fuel cell technology has been around since the 1800s, ”可知, 燃料电池技术从19世纪就开始了, 现在已经21世纪了, 至今已经有200多年的历史了, 故D项正确。
4. What can we infer from the passage?
A. There will be no gasoline for cars.
B. Global warming has been stopped.
C. People can’t afford to buy cars in the future.
D. Future cars will be environmentally friendly.
【解析】选D。推理判断题。根据第二段中的“They are becoming more popular with customers because they cut pollution and improve fuel efficiency. ”可知, 未来的汽车将是环保的, 故D项正确。
