Ten-year-old Barack Obama (奥巴马)was one of the only three black students at his school in Hawaii, the US. He is different from most of the other students. White girls wanted to touch his hair. A white boy asked him if his father ate people.

‘I lied to them that my father was a Kenyan prince(肯尼亚王子). But I kept asking myself who I was.’ said Obama.

However, 37 years later, the boy became well-known. On November 4th, 2008, Obama became the first black president in US history with 297 electoral (选举的) votes.

Obama was born in 1961, to an African father and a white American woman from a small town in the US. He grew up in Indonesia and Hawaii. This unusual background made him wonder who he was. He once turned to alcohol（酒精）to help forget this question.

With the help of his friends, Obama finally turned his life around in the university. His hard work made him star at Harvard University. Later, he became the third black senator (参议员) in US history.

During his race to the highest post in the US, Obama talked about his background. He called for a United States of America, rather than a white America or a black America. ‘Obama’s success has made Martin Luther King’s dream come true. That is : A man should not be judged by the colour of his skin, but by the content of his character.’ he said at the speech in Chicago soon after he was elected.
