SPIRIT LAKE, Iowa -- Towering more than 12 stories above a school playground, a pair of wind turbines(涡轮机) transform the usts blowing over the lakes and ridges sur-rounding this northern Iowa town into power that provides about half of the school district' s electrical needs.

     Students here can "look right out the back door" to see the giant turbines capture the wind and learn how they can produce power. More than 80 schools across the USA have installed some type of wind turbine, says Ian Baring - Could, senior engineer in a wind technology center at the National Renewable Energy Laboratory in Golden, Colo.

      Now, a program called Wind for Schools is aiming to bring smaller turbines to six states:Colorado, Idaho, Kansas, Montana, Nebraska and South Dakota. The program, sponsored by the U.S. Department of Energy' s Wind Powering America program at the National Renewable Energy Laboratory, is the first program to use smaller turbines with a mission of educating students and the cmmnunity about wind power.

      In Faith, S. D. , home to one of the schools hoping to build a small wind turbine in the next couple of years, a fierce wind blows across the plains most days. Angela King, who teaches science in grades 7 to 12 in Faith, believes a turbine wiI1 give students learning about wind energy the chance to "see it happening, rather than just reading it in a book. "

      Much of the first year of the three - year program has been spent identifying schools hoping to join the program. South Dakota, for instance, announced its eight school districts over the summer. About five schools in Kansas have the turbines, and schools in Montana, Idaho and South Dakota are now preparing sites and will have them installed during this school year.Now, the goal is to add wind turbines at about five schools per year in each state, for a total of about 30 per year overall, Baring - Gould says.

A spirit of adventure, curiosity about different cultures and the desire for a challenge can be found in young people everywhere. More and more students in China are backpacking around the country.
According to the China Youth Travel Service, Hainan, Dalian, Zhangjiajie and Qingdao were among the most popular spots for young Chinese backpackers last year. Backpacking allows the traveler a greater sense of independence.
“I can no longer put up with the instructions of a tourist guide,” said Huang Ye, a 19-year-old college student in Beijing. “They are always driving you to places that you do not want to go to and trying to make you buy local souvenirs（纪念品）.”
Huang likes to travel as a backpacker. She prefers an independent trip that she took with two friends to Jiuzhaigou in Sichuan Province. There, they chose some scenic spots to visit and avoided the masses of tourists.
Backpackers see the difficulties of such travel as a challenge. Living on bread and water for days on end, wearing the same clothes over and over again and carrying a heavy bag on their backs while climbing a mountain are all character-building experiences.
But perhaps the greatest challenge that a backpacker faces is not a physical one, but mental. They may face loneliness if they travel alone.
Chen Xuewei, 21, suffered when he took off around China last year. “I felt very lonely at the beginning of my journey. A walkman didn’t make me feel better, but rather heightened the sense of loneliness I felt. I even called up my friends to tell them that I wanted to give up and go back to Beijing,” he recalled. But he kept going. He started to make friends and appreciate the local customs. He took lots of photos to record his trip and now he is glad he stuck it out.
Backpackers generally find themselves to be mature（成熟）after their experiences. “Their travel logs（旅行日志）track their development as people.” “When I feel frustrated, I read my travel log again,” said Tang Weifeng, a postgraduate at Peking University. “By reading it, I get a sense that I am better off now than I was when I wrote those words by the light of a torch in a hot tent.”
63. Which of the following is NOT mentioned as one of the advantages of backpacking according to the story?
A. It builds up your character.
B. Through the experience, you learn to live in a tent.
C. Through the experience, you learn to rely on yourself.
D. Through the experience, you learn to deal with loneliness.
64. What does the underlined word “frustrated” in the last paragraph mean?
A. Disappointed.       B. Happy.       C. Tired.       D. Excited.
65. What is the story mainly about?
A. Some backpackers’ experiences.  
B. The advantages of backpacking.
C. Young people’s love of backpacking.
D. The increasing popularity of backpacking among Chinese students and its reasons.
