The United States is a federation formed by the combination of 48 states in the mainland and 2 states of Alaska and Hawaii. The 50 stars in the Star-Spangled Banner, the national flag of the United States, represent these 50 states. As the country is constituted by many races from all around the world with various cultures, the United States is often called the ‘Melting Pot,’ or the ‘Salad Bowl.’ The Immigration Museum located on Alice Island shows the country’s history of immigration. Next to Alice Island is Liberty Island, where the Statue of Liberty stands to symbolize the freedom and democracy of the United States. Today, the United States is the economic power boasting the greatest GDP in the world with more than 12 trillion USD (Source: the World Bank, 2007). The country has expanded its economic influence by entering Free Trade Agreements (FTA) with various countries including Australia and Singapore. Moreover, large enterprises of the United States, such as Coca Cola, Starbucks, McDonalds, and Pizza Hut are spread out to all around the world. Represented by Hollywood films, the popular culture of the United States also has great influence. Movie directors, George Lucas, who produced ‘Star Wars’ and ‘Indiana Johns,’ and Steven Spielberg, who produced ‘E.T.’ and ‘Jurassic Park’ are enjoying global fame.
