work off

总奖金额为245万美金的网球大师系列赛辛辛那提站正选赛15日正式开赛，世界NO.1费德勒自温网之后将首次参赛，与他分在这一区的还有老对手萨芬和阿加西，不过两人将有望火拼争夺一个四强席位，而费德勒在晋级路上也有望遭遇基弗、柳比西奇等难缠对手。 外电报道说：Federer worked off the rust from a five-week layoff caused by a sore foot, and Roddick compensated for an undependable serve during their first-round wins Monday in the $2.45 million tournament. 句中的work off表示"消除；去除"的意思。例如：She works off stress by running for at least half an hour every day.（她每天最少跑步半个小时以减轻精神压力。）Do something to work off your frustration with the job or you'll become ill.（干点什么来减轻你工作上的挫折感，否则你会生病的。） （中国日报网站编）
