In 1961 Obama was born in Hawaii, US. His father is an African and his mother is a white American. He grew up in Indonesia and Hawaii.

When Obama was 10 years old, he was one of only three black students at his school in Hawaii. He felt very different from most other students. White girls wanted to touch his hair. A white boy even asked him what his father was.

“I lied to them that my father was a Kenyan prince(王子). But I kept asking myself who I am,” said Obama.

However, 37 years later, the boy made history. Obama became the first black president(总统) in US history.

This unusual background(背景) made him wonder who he was. He once turned to alcohol (酒) to help forget this question.

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