每日一词学英语(84): make a hash of

英国15岁跳水少年终于修成正果，夺得10米跳台世界冠军。（From Times Online, July 21, 2009: Tom Daley wins stunning diving gold at World Championships）

他是战胜强劲对手后夺冠的。去年北京奥运他曾被寄予厚望，结果未获奖牌，这次世锦赛凭借对手失误夺冠。Daley, who had a disappointing Olympics last year despite the high hopes of him winning a medal, came into the last round in third place but both Qiu Bo, the pre-event favourite, and Matthew Mitcham of Australia, the Olympic champion, made a hash of their final dives to hand him the gold medal. 两名强手最后一跳没发挥好，结果将金牌拱手送给Tom Daley。
