　     Ashia Hansen is the world indoor triple jump (三级跳)record holder. She has given up getting a place in the Great Britain team for next weekend's European Indoor Championships（锦标赛）. Hansen, whose injured leg almost brought her career（事业） to an end three years ago, won the third prize at the Union Jumps International last Wednesday. “I could look for another competition, but it's pretty pointless（无意义的）. I just have not got enough speed to jump what I want to, ” says Hansen. She still wants to take part in this year's World Championships in Osaka. She says, “I can actually smile now because I know I have not lost anything in jumping ability. It's just that the speed is not there. I've now got three months to find that before the summer season starts. ”
