听力原文： Bobby Moore was a famous English soccer player who led the England team to victory against West Germany in the 1966 World Cup Final. As a superb defender, Moore played 108 games for England's national team from 1962 to 1970 and was captain 90 times. His professional soccer career spans 19 years and 668 matches, a record with no match so far in England. Moore was born in Barking, East London, in 1941. His full name was Robert Frederick Moore. He began playing club soccer in the early 1960s. He was named England's Footballer of the Year from 1963 to 1964. Moore was known for his sportsmanship on the field. He was not inclined towards wild celebration of girls. In 1967, he was made a member of the Order of the British Empire. Moore retired from playing in 1977, and after spending brief periods managing professional soccer teams, he concentrated on developing a sports marketing company and doing media work. He was sports editor of Sunday Sport from 1986 to 1990 and a regular commentator for London's Capital Radio Station from 1990 to 1993.
