Question: Article: A senior United Nations Children's Fund (UNICEF) official on May 29 praised China for its remarkable achievements in children s welfare. A. H. M. Farook, UNICEF's operations area officer for China and Mongolia said that China "can be very satisfied to tell the whole world what can be done with limited resources to help its children to grow healthily and happily." China's child population makes up one-filth of the world's total. "The reason behind the tremendous achievement is China's long tradition of caring for children home at home and in society." he said. "What's more is that Chinese people have always given special attention to children who are in special need." The UN official made the remarks when addressing a group of 50 children and staff from the Beijing Children's Welfare Home at the Shangri-la Hotel, Beijing. The hotel invited the orphans to share snacks, sing, dance and play games at a park inside the hotel for a "Share the Sunshine" party, as a prelude to celebrations to mark the Children's Day. The Beijing children s Welfare Home, set up soon after New China, was founded in 1949, has at present more than 400 children. A leading official of the welfare institution said that the children live a happy life and that the agency spends about 400 yuan a month for an average orphan. An average Chinese worker earned 440 yuan a month during the first quarter this year. Gu Xiaojin, deputy secretary-general of the China Youth Development foundation (CYDF), said people from all walks of life had contributed to the welfare of the Chinese children. She said that CYDF set up the Project Hope in 1989, which calls on people across the country to donate money to help poor children to continue their schooling. By the end of last year, she said, CYDF had collected nearly 700 million yuan in donations, which has helped the establishment of 2, 074 Hope primary schools and enabled more than 1.25 million dropouts to return to school classrooms. Three "Hope Stars" also attended the party. They were model teenagers chosen among students who are economically supported by the Project Hope to further their nine-year compulsory studies in the poverty-stricken regions. They will be torchbearers for the Chinese Team for the upcoming Atlanta Olympic Games this year.

Question: Article: On Nov.18th, 1908, three men went up in a balloon. They started early in London. The headman was Augusta Gaudron, and the other two men were Tannar and Maitland. They had a big balloon and they were ready for a long way. Soon they heard the sea. They were carrying the usual rope, and it was hanging down from the basket of the balloon. At the end of the rope they had tied a metal box. This could hold water, or it could be empty. So they were able to change its weight. It was for use over the sea. They were also carrying some bags of sand. After the sun rose, the balloon went higher. It went up to 3,000 meters, and the air was very cold. The water in the balloon became ice. Snow fell past the men's basket, and they could see more snow on the ground. The men tried to throw out some more sand, but it was hard. They tried to break the icy sand with their knives, but it was not easy. The work was slow and they were still falling, so they had to drop some whole bags of sand. One of them fell on an icy lake and made a black hole in the ice. At last they pulled the box into the basket. It was still snowing; so they climbed up to get away from the snow. They rose to 5,100 meters! Everything became icy. They were so cold that they decided to land. They came down in Poland heavily but safely. They had travelled 1,797 kilometers from London!
