History has arrived
Nine-year-old Barack Obama was looking through magazine. But the African-America boy was shocked by
a series of photos. The pictures were of a black man who destroyed his skin with chemicals that promised to
make him white.
For the first time, the boy began to doubt who he was. "I stood in front of the mirror and wondered if
something was wrong with me," Obama said.
However, now the boy who used to struggle with his identity doesn't see it as a problem any more, but an
advantage for his career. Last week, Obama made history by being elected as the first black president of the
US. He defeated John MaCain in a landslide (压倒性的) victory.
Obama's story starts in opposite corners of the world. His white mother was born in the heartland of the
US. His black father grew up in a tiny village in Kenya. They met during in Hawaii, but his father left the family when Obama was just two years old and his mother moved to Indonesia.
At 10, Obama moved back to live with his white grandparents in Hawaii where his sense that he didn't
belong grew. At his class a white boy asked Obama if his father ate people. Out of embarrassment, Obama lied
to his classmates that his father was prince, "I kept asking who I am and I ended up trying drugs and
drinking," Obama recalled.
Things came to change after the young man made friends with those with a similar background at college.
Their experiences back in Africa helped Obama to finally face up to his African origin. He worked hard to
become a star at Harvard Law School and the third black senator (参议院) in US history.
At the beginning of his campaign for the White House, few people viewed Obama favorably (赞同地).
Many doubted his unusual background, which left him neither "black" enough nor white enough.
But Obama turned his pain of growing up into a tool to make Americans believe: "There is not a black
America, an Asian America. There's the United States of America."
Barack Obama's victory is "a historic victory that promised change and overcame centuries of prejudice
(偏见). His success fulfilled Martin Luther King's dream that a man he judged not by the color of his skin, but
by the content of his character," wrote ABC news.
