on a roll

美網大賽前的重要熱身賽--辛辛那提大師賽決賽結束，世界球王費德勒毫無懸念的連續第六次擊敗老對手羅迪克，摘得本賽季個人的第四個大師系列賽冠軍，同時將2005年的總戰績提升到64勝3負。本場決賽之前，費德勒在決賽中已經保持了21連勝，同樣對羅迪克也保持了五連勝。外電報道如下： When Roger Federer reaches a tournament final, he doesn't lose. Nobody knows that better than Andy Roddick. The unflappable Federer won his 22nd straight final on Sunday, beating the exasperated American 6-3, 7-5 for the Cincinnati Masters championship and his ninth overall title this season. Federer improved to 10-1 against Roddick, who tried every tactic but still came up short. Federer has won the last six times they've met, including the last two Wimbledon finals. The world's top-ranked player for the last 81 weeks, Federer heads into the U.S. Open fit, relaxed and on a roll. He took time off after winning his third straight Wimbledon, looking to recharge and rest a sore foot. 文中的on a roll表示"連連獲勝中；連續交好運中"。If someone is on a roll, they are successful or lucky for a short period of time. 例如：When he won one game after another, it was obvious he was on a roll.（當他贏得一場又一場比賽時，很明顯他正在連續交好運。） （中國日報網站編）
