    Lisa Hawkins loves riding her BMX bike （极限单车）and her dream is to go to the Olympics. And Lisa first got interested in BMX racing at the age of ten. Once she hired a bike for a pound immediately  (fall) in love with the sport. "It was the best pound I ever spent," she says. Lisa is only 16 but she already  (have) lots of success, and got first prize in a world BMX competition last year. BMX racing is quite a dangerous sport. But this didn't stop her  (want) to do more competition. Lisa exercises every day. Like many sports people, she (believe) in luck as well as hard work.
