     David finished a college and began to work in a middle school when he was twenty-three. Two years later

he broke his left leg while he was playing football with his students. They took him to a hospital at once. A girl,

Linda, took good care of him there. And they loved each other. As soon as he came out of the hospital, they

married. Linda is a garrulous (饶舌的) woman. She likes telling her husband all she hears in her hospital. David
