阅读理解。 Dolan began swimming at the age of 5,because his elder sister Kathleen was a swimmer.' Whatever she did, I wanted to beat her,' he says. While he says he was a' pool rat' as a child, he didn't aggressively pursue swimming until his freshman year in high school. Golf was his favourite sport then-he played for his high school team until his junior year. Dolan grew up in Arlington, Virginia, and his early development as a swimmer was under the guidance of Rick Curl. At the University of Michigan, he trained under head coach Jon Urabancheck, who helped mold Dolan into an Olympic champion. During breaks from school, Dolan would reunite with Curl, and in the lead-up to Sydney, he returned home full time. In April 2000, Dolan told the Detroit Free Press,' My whole career I had gone back and forth, but now I'm spending the whole year with Rick. But where I go and swim, I'll always be linked to Michigan and to Jon, just as I will to Rick.' Dolan was 18 when he entered the 1994 World Championships. He remembers being near all the big stars and noticing they were staring at him. He won the 400 IM title in world record time. He successfully defended his world title four years later in Perth, Australia. Dealing with asthma (哮喘) and poor air quality, Tom Dolan could hardly breathe at the 1996 Atlanta Games. But as the top world champion and world record holder in the 400-metre individual medley(混合泳),he was determined to win Olympic gold.' My legs were burning pretty bad, and I couldn't get any oxygen. I knew it was between me and Eric, and I just gave it everything I had coming into the wall,' says Dolan. He touched first, just ahead of fellow American Eric, who got the silver. 1.
