　　American scientists have developed the first material that repairs itself. The material is a form of plastic that has been engineered to fill breaks in its surface. Plastics are used today in everything from airplane wings to hundreds of object found in the home. Scientists wanted to find a way to make objects made of plastic last longer. The researchers hope their new discovery can be used to make objects that are difficult or impossible to replace. The surface of plastic objects breaks over time. Very small breaks develop every time a plastic object is used. The researchers wanted to find out how to stop plastic from developing small breaks that weaken and destroy it. They found the answer in the chemical structure(构造)of plastic itself. Plastic is made of monomers(单体). These monomers link together to form polymers(聚合物). Polymers give plastic its ability to be shaped and its strength. The research team found a way to make plastic that contains very small balloons filled with monomer liquid(液体). When the new plastic cracks(裂开), the monomer liquid is let out and flows into the crack. Thus the break is repaired. The repaired plastic has seventy – five percent of the strength of undamaged plastic. The new self – repairing plastic is not yet ready for production. But it has several possible uses. One could be in space vehicles where parts cannot be repaired or replaced. Another possible use might be in bridges. And it could be used in people, to replace bone joints that have become broken or damaged.

　　( B ) S. H. E. is going to sing at the CCTV annual Spring Festival Evening Party, is that true? cried out Peng Weiye, a Senior 2 girl in Shanghai and die – hard (铁杆的)S. H. E. fan. After checking it on the Internet, Peng quickly phoned friends to spread the news. For fans like her, S. H. E.‘s performance is perhaps the only part of the old fashioned evening to get excited about. The Taiwanese band is made up of Selina, Hebe and Ella. Their name comes from the first letter of each of the singers’ English names. Last week S. H. E. announced they will perform in Las Vegas, US, over Christmas and then in Guangzhou on January 15. At their Shanghai show on October 30, hundreds of parents waited outside the Hongkou Stadium. Inside, thousands of teenagers sang, cried and shouted as the band performed.“I love their music, healthy image and everything related to them. Thank God that, although my parents don‘t understand why I love them so much, they still bought me a ticket for that show,” said Peng about the Shanghai performance. It is not just on the mainland that the three girls have thrilled (make sb. excited) audiences. In the past year the band has passed through Taiwan, Hong Kong and even Singapore and Malaysia. When the three high school girls entered a singing contest in Taiwan in 2000, none of them ever dreamed of being a superstar. “We had never met before, and we didn’t talk at all at the beginning,” recalled Ella. When asked about the secret of their success, she said, “Our average looks and not-so-expensive clothes keep us close to our fans. We are happy to be the girl next door, your singing sisters.”

　　“It‘s really a magical journey, from day-dreaming high school girls to singers performing on the same stage as our idols. Nothing but magical,” she said.
