The fourth of July marks the anniversary of America’s Declaration of Independence from Britain. During the summer of 1776, American colonists were deeply divided. Almost one in three was loyal to Britain. Yet most were increasingly angry about what they considered unfair treatment by the British government. By June, fighting had already taken place between colonial forces and Britain. The idea of independence was spreading.

Delegates (代表) from the thirteen colonies gathered in Philadelphia, Pennsylvania. The Continental Congress decided that a document declaring separation from Britain should be declared. Thomas Jefferson led a committee chosen to write it.

On July 4th, 1776, the Continental Congress voted to approve the Declaration of Independence. It says that people have the right to change their government if it denies them their rights. It states that everyone has the right to life, liberty and the pursuit (追求) of happiness.

Today, the Fourth of July holiday is a time for friends and families to gather. They might play sports and eat hot dogs, hamburgers and other foods cooked outdoors. They might watch a parade in their community. At night, many people gather to watch fireworks bursting in the dark sky.

In Washington, D. C. this year (2011), thousands of people attended a concert with performances by musicians. There was also a huge fireworks show with more than two thousand five hundred shells exploding over the National Mall.

Another event that traditionally took place on the National Mall was the Smithsonian Folk life Festival. This year’s event celebrated the cultures of Mexico and Asian Pacific Americans. Visitors heard the music, eat the food and learn about the many traditions of these cultures.

The third subject of the festival was called “Smithsonian Inside Out”. Smithsonian experts had a chance to present their research and knowledge to the public.
