听力原文： Copenhagen has been the capital of Denmark for 600 years and is also the largest city in Scandinavia. Copenhagen means "merchants' harbor." It grew in size and importance because of its position, the body of water between Denmark and Sweden, guarding the entrance to the Baltic. From its humble beginnings, Copenhagen has become the largest city in Scandinavia. It's the seat of one of the oldest kingdoms in the world. Over the centuries Copenhagen has suffered more than its share of disasters. In the 17th century the Swedes repeatedly besieged it, and in the 18th century it endured the plague and two devastating fires. The British attacked twice during the Napoleonic wars in the early 1800s. Its last major disaster occurred in 1940 when the Nazis invaded Denmark and held it in their grip until 1945 when the British army moved in again, this time as liberators. Copenhagen still retains some of the characteristics of a village. If you forget the suburbs, you can cover most of the central belt on foot, making it a great place to visit.
