1 . Please translate the underlined sentences in the following passage into Chinese or English. 请将下面篇章中的划线句子译成汉语或英语。想象一下在太平洋的巨浪里游4公里是什么样子的。 ________________Do you think you’d feel tired? How about a 180-kilometer road race on a bicycle in the heat of Hawaii? Tired again? 82. Then what about running a marathon in the same conditions? ________________What? Still tired? Now think what it feels like to do the swim, the bike race, and the marathon “back to back”, with no breaks in between, against the toughest and fittest athletes in the world. 如果你想知道这样一个竞赛是否存在, 让我告诉你——它的确存在。 ________________In an event that lasts at least nine hours, 1,500 competitors compete for the title: Ironman. Ironman is a version of the new sport of triathlon (三项全能运动) —a combination of swimming, cycling, and running that is rapidly growing in popularity. 第一届铁人竞赛是由美国人约翰·柯林斯 (John Collins) 在1977年想出来的。 ____________________In a Hawaiian beach bar, a group of friends were debating which of the local sporting events was the toughest, the four-kilometer swim, the 180-kilometer bike race, or the 42-kilometer marathon? ________________They couldn’t reach an agreement and so to settle the argument Collins suggested the unbelievable: why not try to do them all, one after another, on the same day? And so the Hawaiian Ironman triathlon, as the new event was known, was born.
