Twenty-three-year-old Michael Phelps has become a phenomenon (神话) in swimming.
At the 2008 Summer Olympic Games, he won eight gold medals. That was more than the whole Australian team could put together. He beat (打败) Mark Spitz’s 1972 record of seven wins in the pool at the one Olympics. Phelps has put his name next to seven world records.
Nine days, 17 games, morning and night he competed and won. He had to beat former (从前的) world record-holders and gold medalists. He had to turn their wins into old news.
Michael Phelps started to swim at the age of 5. Guess which stroke (动作) he first tried? The backstroke. It’s because he didn’t want to put his face in the water.
By the age of 7, he had taken part in a lot of swimming competitions. At 11, he met Bob Bowman who saw the kid’s great talent.
How did Phelps become so good? He was born with the body of a swimmer. He stands 1.87meters high and has a wide wingspan (臂展). He knows how to use his body to full advantage. His hands and feet are like paddles (踏板) in the water and he has a strong kick.
But that’s not all；he also has the heart and will to win. He thinks that anything is possible as long as you put your mind to it.
Swimming is Phelps’ life. Every day he spends five hours in the water, swimming about 11 kilometers. He never takes a day off. This is a young man who knows what he wants.
“If I didn’t swim my best, I’d think about it at school, at dinner, and with my friends. It would drive me crazy,” he said.
“There are no limits (限制). The more you dream, the further you get.”
