阅读理解。 Ronald Reagan was the only actor to become president of the United States, but other movie stars have also been successful in public office. One of them was Shirley Temple, who is remembered throughout the world as a little girl. She danced and sang in many movies. Shirley began to make movies at the age of five, and she was only nine years old when she played the role of Heidi. In almost every part of the world where movies are seen on television, children and their parents still enjoy Heidi and the other movies of Shirley Temple. Although she has not appeared in a film for over thirty years, her name is still familiar to old and young alike. When Shirley Temple was twenty-one years old, she was already retired from her career as an actress. Twenty years later, many people still thought her as a little girl that Americans had always loved in the movies, but others knew her as an intelligent woman with knowledge of world problems. One of the people who recognized these important abilities was President Richard M. Nixon. In 1969, he appointed (委派) her as a representative (代表) to the United Nations, and this marked the beginning of a new career for the former child star of the movies. One of Shirley's most popular dancing and singing partners was George Murphy, who was twenty-six years older than Shirley. He stopped making movies at about the same time as his young partner. In 1969, he was elected United States senator (参议员) from California, and he served in this office for six years. 1.
