(B)
Martin Luther King, Jr., is well known for his work in civil rights and for his many famous speeches, among them his moving “I Have a Dream” speech. But few people know much about King’s childhood, Martin Luther as he was called was born in 1929, in Atlanta, Georgia, at the home of his maternal grandfather. Martin Luther’s grandfather, the Reverend A.D. Williams, purchased their home on Auburn Avenue in 1909, 28 years before Martin Luther was born. The Reverend A.D. Williams, an eloquent speaker, played an important role in the community because so many people’s lives centered around the church. He allowed his church and his home to be used as a meeting place for a number of organizations dedicated to the education and social advancement of blacks. Martin Luther grew up in this atmosphere, with his home being used as community gathering place, and was no doubt influenced by it.
Martin Luther’s childhood was not especially memorable. His father was a minister and his mother was a musician. He was the second of three children, and he attended all-black schools in a black neighbourhood. The neighbourhood was not poor, however, Auburn Avenue was the main artery through a prosperous neighbourhood that he had come to symbolize achievement for Atlanta’s black people. It was area of banks, insurance companies, builders, jewelers, tailors, doctors, lawyers and other black-owned or black-operated businesses and services. Even in the face of Atlanta’s segregation (种族隔离), district thrived. Dr. King never forgot the community spirit he had known as a child, nor did he forget the racial prejudice（歧视） that was a seemingly insurmountable barrier that kept black Atlantans from mingling with whites.
