a port in Kent, south-east England, and the nearest English town to France. The part of the Channel between Dover and Calais (called the strait of Dover) is 21 miles/34 kilometres wide and is one of the busiest sea routes in the world. The high white cliffs of Dover, which can be seen from a distance, have a special meaning to British people returning home by this route. Dover has a long history. It was a town in Roman times, and its castle, which was the administrative centre of the Cinque Ports, was an important part of the country's defences. 多佛尔(英格兰东南部肯特郡的港口,距法国最近的英国城镇。英吉利海峡在多佛尔和加来之间的部分(称为多佛尔海峡)是世界上最繁忙的海上航线之一。多佛尔高耸的白色悬崖从远处便可以望见,对从这条海路回家的英国人有特殊的意义。多佛尔历史悠久,可追溯至罗马时代,其城堡曾是国防的重要组成部分)
