| 阅读理解 Ellen and Bill County are both teachers. They met in college and became good friends because of their shared love for children. Two years after the couple got married, Ellen saw a huge change in the life of one of her students, a 9-year-old girl. Three years ago both of the little girl's parents had died and there was no one to take care of her. She was taken away to live in a government office. But finally she was taken in and adopted by a family and became their daughter. Ellen said that she noticed the difference in the child's life after she was placed in a permanent home and thought that maybe she and her husband could help a child in a similar way. They decided to become temporary parents and to take a child into their home on the weekends when the real parents could not take care of him or her. The pair planned to have their own children in a few years, but decided that this would be a way to give to the community in the meantime. The couple quickly grew to love one of the children they looked after. When he became legally available, Billy became the first child they took in permanently. Six months after adopting Billy, Ellen was told by her doctor that she was unable to have children naturally. Ellen says she knew then that adoption was the way she was meant to have a family. Since adopting Billy, now 17, Ellen and Bill have adopted five more children --- Rose,16； Albert, 11; Joshua, 5 and in June 2003, they added biological brother and sister Tyler and Rylee to the County family. The County family has been recognized for their work on adoption, and have received many awards for their efforts. Last June, the family was even interviewed on the television show, "Adoption Stories". Ellen says she would like to encourage other families to adopt children. She adds that the best part of being a mother of six is: "Giving Josh a bath, putting a band-aid on a cut knee or just the everyday mom things, that makes motherhood such an honor and a privilege." 1.
