Dan Buettner gets off the phone with people by saying, “live large”. It’s a motto he’s followed. A writer and adventurer, he has bicycled around the world, gone through several ventures to teach young people about different cultures and is now traveling to different countries with a team of doctors and demographers (人口学家), pinpointing (确定) the places where people live longest.

“I just became obsessed with finding out what it is that helps these people,” he said as he made plans for another trip. Buettner’s newest expedition is to the Nicoyan Peninsula, on the Pacific coast of Costa Rica.

For reasons doctors are striving to understand, men in Nicoya live to the age of 100 four times as often as men in the United States - even though their medical care costs only about 7 percent as much. Buettner labels Nicoya a “blue zone”, a place where many factors combine to allow people to live longer and better. Buettner has already profiled three other blue zones:

The mountainous Italian island of Sardinia, where farmers work hard in the fields, drink red wine, eat fruits and vegetables they grew themselves, and are taught to respect their elders.

In Okinawa, there is no word for “retirement” - but there is another word, Ikigai, which is translated roughly to “purpose” or “that which makes one’s life worth living”. Men there have one fifth as many cases of cancer as Americans, and a quarter as many cases of heart diseases there.

Loma Linda, Calif., about an hour’s drive east of Los Angeles. Why should one city stand out amid the sprawl (延伸处) of Southern California? Perhaps, said researchers, because the Seventh Day Adventist Church there gives people a powerful sense of community.

65. We can infer from the passage that ________.

A. future cars will become 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 stopped

64. According to the passage, what is the major cause for global warming?

63. 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 that pollute the air.

C

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 $1million and 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.

Carmakers have been working to develop vehicles that are better for the environment. They are developing cars that use fuel other than gasoline.

What is fuel cell technology?

Fuel cell technology works by changing 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 (一氧化碳) and carbon dioxide. Many scientists said these gases were 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 said.

Fuel cell technology has been around since the 1800s, but scientists have yet been to perfect it. They said it might take years before the technology is ready for widespread use.

Creating environmentally-friendly cars.

Another earth-friendly car has already been 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 (效率).
