National day of America.

This Sunday, is the national day of the US. I went to the Charles River with my friends, there are so many people that stand in the side of river, we are all waiting for the same thing---fireworks. Last time which I saw the fireworks is the Spring Festival in China. On that day, people's enthusiasm affect me, we all felt cheerful atmosphere around whole city, it is really a happy night for us. On Friday, we went to the State House which government work in. It is a old and beautiful building that is filled with political air.
