A Brief Introduction
The United Nations was founded in 1945 after World War II to replace the League of Nations, to stop wars between countries, and to provide a platform for dialogue. It contains multiple subsidiary organizations to carry out its missions. In 1945, the UN had 51 members. It now has 193, of which more than two-thirds are developing countries. Because of their numbers, developing countries are often able to determine the agenda of the Assembly ，the character of its debates, and the nature of its decisions. For many developing countries, the UN is the source of much of their diplomatic influence and the principal outlet for their foreign relations initiatives.
The Locations
Four of the five principal organs are located at the main United Nations Headquarters located on international territory in New York City. The International Court of Justice is located in The Hague（海牙）, while other major agencies are based in the UN offices at Geneva, （日内瓦）, Vienna（维也纳）, and Nairobi （内罗比，肯尼亚首都 ）.Other UN institutions are located throughout the world.

General Assembly
United Nations General Assembly hall
The General Assembly is the main deliberative assembly of the United Nations. Composed of all United Nations member states, the assembly meets in regular yearly sessions under a president elected from among the member states. Over a two-week period at the start of each session, all members have the opportunity to address the assembly. Traditionally, the Secretary-General makes the first statement, followed by the president of the assembly. It always takes three months.The first session was convened on 10 January 1946 in the Westminster Central Hall in London and included representatives of 51 nations.
Four of the official languages are the national languages of the permanent members of the Security Council (the United Kingdom and the United States share English as official language); Spanish and Arabic are the languages of the two largest blocs of official languages outside of the permanent members (Spanish being official in 20 countries, Arabic in 26). Five of the official languages were chosen when the UN was founded; Arabic was added later in 1973.
