英语翻译在NYtimes上看到一篇东东,貌似World expo和World'fair是有不同的,可中文翻译过来不都是世

两个是一样的 参考——Universal Exposition or Expo (short for "exposition",and also known as World Fair and World's Fair) is the name given to various large public exhibitions held since the mid-19th century。They are the third largest event in the world in terms of economic and cultural impact,after the FIFA World Cup and the Olympic Games。[citation needed] They have been organized for more than one and a half centuries — longer than both the (modern) Olympic Games and the World Cup。
