　　New York City consists of five boroughs: Manhattan, Brooklyn, Queens，the Bronx and Staten Island.The population is about 7.5 million living in Manhattan. Manhattan，the center of the city，is on an island between the Hudson River and the East River. Most of the famous buildings such as the Empire State and the United Nations and other skyscrapers are in Manhattan. Some of its districts are Broadway，which has many theaters and cinemas; Fifth Avenue, with stores and apartments; Greenwich Village，where many artists and writers have lived；and Central Park，with a small zoo and a skating rink. From Manhattan you have to cross to the other boroughs through a tunnel or over a bridge. The bridge from Brooklyn to Staten Island is the longest in the world.
