2012年商务英语考试伦敦实战词汇（10）

Meaningful world records have only been achieved in a few Olympic sports. At the Beijing Games, world records were broken in 33 separate events: one in women's team archery, four in weightlifting, five in athletics (of which Usain Bolt set three), two in track cycling and the remainder in swimming.
考试用书Since 2009, wearing considerably slower suits, only Ryan Lochte in the men's 200m medley and China's Sun Yang in the men's 1500m freestyle have set new world records, both at last year's World Championships. No woman has broken a world record since the 2009 suits were banned.
