小组讨论并完成此次英译汉作业,每个小组提交一份译文。 How Did Eliud Kipchoge ( 埃鲁德•基普 ) Break the Marathon Record So Soon? That was fast. In a historic run through a Viennese park Saturday morning, Eliud Kipchoge of Kenya broke the two-hour barrier in the marathon, following through on his pre-race musings: “I don’t know where the limits are, but I would like to go there.” Mr. Kipchoge’s performance has echoes of breaking the 4-minute-mile barrier in the 1950s. It’s not that we didn’t think humans would get here — scientific barriers based on round figures are fundamentally arbitrary after all. It’s that we didn’t realize it would be so soon. As recently as last year, one expert predicted the two-hour mark wouldn’t be broken until 2028 or 2029. So what made it possible? It’s not so different from when Sir Edmund Hillary ( 埃德蒙 •希拉里爵士 ) and Tenzing Norgay ( 丹增 •诺尔盖 ) summited Everest for the first time in 1953, aided by supplementary oxygen. In both cases, the requirements were extraordinary determination, outstanding physical condition — and a heavy dose of science. When he finished, Mr. Kipchoge compared what he’d just accomplished to man walking on the moon. It’s an apt analogy. Rather than showing what humanity is naturally capable of, his performance indicates what we can achieve with a boost from technology.
