　　To find out whether mice put such sounds together in song-like

　　, the researchers recorded the sounds of 1 mice. Using computer

　　, they were able to separate the sounds into specific types of syllables(音節(jié)), and found the mice produced about 10 syllables per second.

　　The results showed that nearly all of the mice repeated sequences(順序) of syllables in different patterns. That’s enough to meet the definition of what scientists

　　The first time my eyes were opened to children's rights was when I was 15. A representative of Free the Children gave a speech at my school, sharing, this story I will never forget. Craig Kielburger was 12 when he came across an article about a boy of his age who escaped from child labor and was murdered for speaking about his experiences. Craig was upset and took the article to school. He asked who would help him and with a group, of friends, started Free the Children.

　　Craig traveled to countries where he saw child laborers and poverty firsthand. He also started giving speeches to people three times his age. He was even nominated(提名) for a Nobel Peace Prize and received the Nelson Mandela Human Rights Award. His organization has already helped over a million children.

　　I could not believe a kid three years younger than me had accomplished so much. His story motivated everyone who heard it to do something about the problems of the world.

　　That first burst of awareness faded, but a year later an organization at my school announced a meeting about social justice. Mare Kielburger, the elder brother of Free the Children's founder, came to my school to speak and for the second time I heard the story how Craig started the organization, but this time from a person who had been there since the beginning. Mare described his visits to underdeveloped countries and the influence on his life, telling us how we could make a difference. I was completely attracted.

　　Free the Children had set up campaigns that help children get education, medical care and food. When our advisor asked if we' would like to get involved, we responded with a unanimous yes.

　　Our group set to work realizing our goal of helping build a school by raising $6,000. It was a great challenge, but if other children had done it, so could we. I began to volunteer as a tutor at a grade school. It's tough sometimes when the children don't cooperate. But I think about all those children who can' t get an education and realize it's all worth it.

　　Every child should get an education and Free the Children has helped me understand that. Devoted to the rights of children, it has also helped me see that I can do something to help other children. I have the power to change the world and I'm going to use it. I think when the students at our school see what their money has done. They will realize they can make a difference, too.

　　Two hours from the tall buildings of Manhattan and Philadelphia live some of the world's largest black bears. They are in northern Pennsylvania's Pocono Mountains, a home they share with an abundance of other wildlife.

　　The streams, lakes, meadows(草地), mountain ridges and forests that make the Poconos an ideal place for black bears have also attracted more people to the region. Open spaces are threatened by plans for housing estates and important habitats(棲息地) are endangered by highway construction. To protect the Poconos' natural beauty from irresponsible development, the Nature Conservancy(大自然保護(hù)協(xié)會(huì)) named the area one of America's "Last Great Places" .

　　Operating out of a century-old schoolhouse in the village of Long Pond, Pennsylvania, the conservancy's Bud Cook is working with local people and business leaders to balance economic growth with environmental protection. By forging partnerships with people like Francis Altemose, the Conservancy has been able to protect more than 14,000 acres of environmentally important land in the area.

　　Altemose's family has fanned in the Pocono area for generations. Two years ago Francis worked with the Conservancy to include his farm in a county farmland protection program. As a result, his family's land can be protected from development and the Altemoses will be better able to provide a secure financial future for their 7-year-old grandson.

　　Cook attributes the Conservancy's success in the Poconos to having a local presence and a commitment to working with local residents. "The key to protecting these remarkable lands is connecting with the local community," Cook said. "The people who live there respect the land. They value quiet forests, clear streams and abundant wildlife. They are eager to help with conservation effort."

　　Some houses are designed to be smart. Others have smart designs. An example of the second type of house won an Award of Excellence from the American Institute of Architects.

　　Located on the shore of Sullivan's Island off the coast of South Carolina, the award-winning cube-shaped beach house was built to replace one smashed to pieces by Hurricane (颶風(fēng)) Hugo 10 years ago. In September 1989, Hugo struck South Carolina, killing 18 people and damaging or destroying 36,000 homes in the state.

　　Before Hugo, many new houses built along South Carolina's shoreline were poorly constructed, and enforcement of building codes wasn't strict, according to architect Ray Huff, who created. the cleverly-designed beach house. In Hugo's wake, all new shoreline houses are required to meet stricter, better—enforced codes. The new beach house on Sullivan's Island should be able to withstand a Category 3 hurricane with peak winds of 179 to 209 kilometers per hour.

　　At first sight, the house on Sullivan's Island looks anything but hurricane-proof. Its redwood shell makes it resemble "a large party lantern (燈籠)" at night, according to one observer. But looks can be deceiving. The house's wooden frame is reinforced with long steel rods to give it extra strength.

　　To further protect the house from hurricane damage. Huff raised it 2.7 meters off the ground on timber(7(木頭) pilings (屋基)—long, slender columns of wood anchored deep in the sand. Pilings might appear insecure, but they are strong enough to support the weight of the house. They also elevate the house above storm surges. The pilings allow the surges (波濤洶涌) to run under the house instead of running into it. "These swells of water come ashore at tremendous speeds and cause most of the damage done to beach-front buildings," said Huff.

　　Huff designed the timber pilings to be partially concealed(隱藏)by the house's ground-to-roof shell. "The shell masks the pilings so that the house doesn't look like it's standing with its pant legs pulled up," said Huff. In the event of a storm surge, the shell should break apart and let the waves rush under the house, the architect explained.

　　51. After the tragedy caused by. Hurricane Hugo, new houses built along South Carolina's shore line are required________.

　　A. to be easily reinforced

　　B. to look smarter in design

　　C. to meet stricter building standards

　　D. to be designed in the shape of cubes

　　52. The award-winning beach house is quite strong because_______.

　　A. it is strengthened by steel rods

　　B. it is made of redwood

　　C. it is in the shape of a shell

　　D. it is built with timber and concrete

　　53. Huff raised the house 2.7 meters off the ground on timber pilings in order to __________ .

　　A. withstand peak winds of about 200 km / hr

　　B. anchor stronger pilings deep in the sand

　　C. break huge sea waves into smaller ones

　　D. prevent water from rushing into the house.

　　54. The main function of the shell is ________.

　　A. to strengthen the pilings of the house

　　B. to give the house a better appearance

　　C. to protect the wooden frame of the house

　　D. to slow down the speed of the swelling water

　　55. It can be inferred from the passage that the shell should be _____.

　　A. fancy-looking

　　B. waterproof

　　C. easily breakable

　　D. extremely strong
