麻烦各位帮我用英语复述一个故事！

In June 1985, two British mountaineers Joe Simpson and Simon Yates made the first-ever climb of the West Face of the 21,000 foot snow-covered Siula Grande mountain in Peru. It was an exceptionally tough assault - but nothing compared to what was to come. Early in the descent, Simpson fell and smashed his right knee. Yates could have abandoned him but managed to find a way of lowering him down the mountain in a series of difficult drops blinded by snow and cold. Then Simpson fell into a crevasse and Yates eventually had no choice but to cut the rope, utterly convinced that his friend was now dead.

In his subsequent book on the climb entitled "Touching The Void", Joe Simpson wrote:

"As I gazed at the distant moraines, I knew that I must at least try. I would probably die out there amid those boulders. The thought didn't alarm me. It seemed reasonable, matter-of-fact. That was how it was. I could aim for something. If I died, well, that wasn't so surprising, but I wouldn't have just waited for it to happen. The horror of dying no longer affected me as it had in the crevasse. I now had the chance to confront it and struggle against it. It wasn't a bleak dark terror any more, just fact, like my broken leg and frostbitten fingers, and I couldn't be afraid of things like that. My leg would hurt when I fell and when I couldn't get up I would die."

The survival of Yates himself was extraordinary. That Simpson somehow found a way of climbing out of the crevasse after 12 hours and then literally crawled and dragged himself six miles back to camp, going three days and nights without food or drink, losing three stone, and contracting ketoacidosis in the process, would be the stuff of heroic fiction if it was not so true. Indeed, six operations and two years later, he was even back climbing. All because, against all the odds, he tried ...

1985年，英国登山运动家耶茨（Simon Yates）和辛普森（Joe Simpson）前往南美秘鲁征服高达2万多英尺的安第斯山某峰。在成功登顶后下撤途中，Joe不慎跌下陡坡，摔断右腿。Simon用救生绳拉住他，在暴风雪中一起下降。但下降到3千英尺时，Joe不幸又坠空在一个冰崖动弹不得，无法将自己的重心转移开救生绳。经一段时间的努力，悬系两人生命的绳子不堪重负，随时都有同时跌下山谷的危险，温度已经降至-70℃，严寒已把两人冻僵。Simon已随绳索下降，不得以只好割断绳索，自己攀出陡壁，回到营地。Joe随着割断的绳索跌进深渊，但怀著坚强的生存意志，拖著折断的双腿爬出深渊，历经三天千辛万苦，就在Simon准备撤离时，Joe拖著伤腿出现在他的眼前……
　这是一个真实的故事。根据1988年辛普森的同名回忆录改编，采用真人采访与再现场面结合的手法，由登山亲历者Joe Simpson和Simon Yates讲述，并由演员重现当时情景。本片的情节是极其震撼人心的。这震撼不止是在耶茨割断绳索的那一刻，更在于辛普森绝地求生的毅力。这两位登山者在挑战自然极限的同时，也在挑战着自身的极限，不管是心理上还是生理上。人在绝境下究竟会爆发出多少能量？我想，这是个永远不可能被量化的东西。
1985年六月，两个英国登山者Joe Simpson和Simon Yates来到秘鲁，第一次攀登海拨21，000英尺白雪覆盖的Siula Grande山西坡。上山是一趟非常艰难的旅程，但比起后来遇到的困难就只是小儿科了。在下山途中，Simpson摔断了右腿。Yates本来可以扔下Simpson，可是他没有。风雪和寒冷使他们看不清前面的路，Yates想方设法把Simpson带下山去。他们轮流把对方往下放。后来Simpson掉进了一个裂缝里，Yates没有办法，只好割断了绳子。他相信他的朋友是九死一生了。Simpson在他的书《冰峰168小时》里写道：我看着那遥远的冰碛石，我知道我必须至少要试一试。我很可能会在那些巨石中丢了性命。但是这个念头没有让我惊慌，因为它看起来很有道理并切合实际。这就是事实。我可以计划一下，如果我死了，那不足为奇，但我不能在这里等待死亡降临。对死亡的恐惧对我的影响不像在裂缝里时那么大了。我现在能面对它并努力击倒它。死亡不再是无望的阴暗的恐惧，它只是一个事实，就像我的断腿、我冻僵的手指一样的事实。我不能害怕这样的事实。如果我摔倒，我的腿会断，但是如果我不站起来，我会死。Yates自己能活下来也令人难以置信。12个小时后Simpson不知怎么想办法爬出了裂缝，拖着他自己慢慢地爬了六公里回到营地。他爬了三天三夜，没有食物没有水，体重轻了42磅，途中还感染了酮症酸中毒。如果这不是事实的话，那就是英雄式虚构小说的情节了。事实上，经过六场手术，两年后Simpson甚至又开始爬山了。一切只因为，对于种种可能发生的事，他选择了去尝试。
