Some historians believe that he is based on a real person, Samuel Wilson. During the War of 1812, Wilson sold meat to American troops. Wilson labeled the meat barrels (桶) US. This meant that it was for the army. At that time, US was not used to mean United States. An officer asked what the US on the barrels meant. A soldier replied, Uncle Sam, meaning Samuel Wilson. The Uncle Sam image (形象) today shows a man with a beard, a stars and stripes (星条旗) top hat, and a suit. Thomas Nast created this image in about 1838. It represented the government in Nasts political cartoons. Some people believe that Nast based his image on Dan Rice, a popular entertainer. Rice performed while wearing a top hat and suit. Others think it was James M. Flagg that drew the most famous image of Uncle Sam in 1917, during World War I. It shows a serious man pointing a finger at the viewer and says Uncle Sam wants you. Flagg drew this enduring image to encourage Americans to join the U.S. Army. It has been used for this purpose ever since.Today, Uncle Sam is a symbol of the United States that is recognized around the world.21.

He was such a life-changer to me that I left that class determined never to underachieve again. He not only taught me to perform better and achieve more success than expected, he, more importantly, taught me to think. He convinced me, as much by example as words that it was my moral obligation(义务) to do so and to serve others.Neither of us could know how our relationship would evolve over the years. When I came back to Bohunt to teach English, I worked for Dr. Whitworth, the department chair. My discussion with him was like graduate seminars in adolescent development, classroom management and school leadership.After several years, I was named department chair, and our relationship shifted again. I thought that it might be awkward chairing the department, since all of my former English teachers were still there, but Dr. Whitworth supported me throughout. As the former chair, he knew when to give me advice about curriculum, texts and personnel, and when to let me chart my own course.In 1997, I needed his opinion about leaving Bohunt to become principal at another school. If he had asked me to stay at Bohunt, I might have. Instead, he encouraged me to seize the opportunity.Five years ago, I became the principal of Bohunt.
