用英语介绍美国首都华盛顿，要三个部分

Washington, D.C. is the capital city of the United States of America. "D.C." is an abbreviation for the District of Columbia, the federal district coextensive with the city of Washington. The city is named after George Washington, military leader of the American Revolution and the first President of the United States. The District of Columbia and the city of Washington are coextensive and are governed by a single municipal government. For most practical purposes, they are considered to be the same entity, though this was not always the case. As late as 1871, when Georgetown ceased to be a separate city, there were multiple jurisdictions within the District. Although there is a municipal government and a mayor, Congress has the supreme authority over the city and district, which results in citizens having less self-governance than residents of the states. In addition to lacking full self-governance, the residents of the District also lack full congressional representation .译文：华盛顿,D.C.是美国政府的首都."D.C".是哥伦比亚特区的缩写,与华盛顿共同组成联邦政府所在地区.城市以纪念乔治.华盛顿而命名,他是美国独立战争的军事领袖和第一位美国总裁.哥伦比亚特区和华盛顿城市被e799bee5baa6e997aee7ad94e59b9ee7ad9431333332636334同一个市政府管理.最实际的目标是,将他们认为是同一个实体，虽然这并不总是事实.至1871,当乔治镇不再是一座独立城市的时候,该地区有多重司法.虽然有一个市政府和一个市长,国会对城市和地区用有绝对权利,其结果是比州其他地方相比，该地区居民更处于无政府管辖状态。除了缺乏完整统治政府,该地区的居民也缺乏最高立法机关的完善代表。还有这个，比较长，但没有译文~~O(∩_∩)OWashington, D.C. (pronounced /ˈwɒʃɪŋtən ˌdiːˈsiː/), formally the District of Columbia and commonly referred to as Washington, the District, or simply D.C., is the capital of the United States, founded on July 16, 1790. The City of Washington was originally a separate municipality within the Territory of Columbia until an act of Congress in 1871 effectively merged the City and the Territory into a single entity called the District of Columbia. It is for this reason that the city, while legally named the District of Columbia, is known as Washington, D.C. The city is located on the north bank of the Potomac River and is bordered by the states of Virginia to the southwest and Maryland to the other sides. The District has a resident population of 591,833; however, because of commuters from the surrounding suburbs, its population rises to over one million during the workweek. The Washington Metropolitan Area, of which the District is a part, has a population of 5.3 million, the ninth-largest metropolitan area in the country.Article One of the United States Constitution provides for a federal district, distinct from the states, to serve as the permanent national capital. The centers of all three branches of the federal government of the United States are located in the District, as are many of the nation's monuments and museums. Washington, D.C., hosts 174 foreign embassies as well as the headquarters of the World Bank, the International Monetary Fund (IMF), the Organization of American States (OAS), the Inter-American Development Bank, and the Pan American Health Organization (PAHO). The headquarters of other institutions such as trade unions, lobbying groups, and professional associations are also located in the District.The United States Congress has supreme authority over Washington, D.C.; residents of the city therefore have less self-governance than residents of the states. The District has a non-voting at-large Congressional delegate, but no senators. D.C. residents could not vote in presidential elections until the ratification of the Twenty-third Amendment to the United States Constitution in 1961.
