[解析]
(1)细节理解题。根据第一段Back in 2003,Ralston was climbing in the remote,mountainous area of Southwestern Utah,when the unthinkable happened:Aron got stuck in a crevice (裂缝) in the rocks and pinned by a big stone that weighed over 360 kilograms.(早在2003年,拉尔斯顿在犹他州西南部偏远的山区登山时,不可思议的事情发生了:阿伦被卡在岩石缝隙中,被一块重达360公斤的大石头压住。)可知阿伦被卡这件事是难以预料的。故选C。
(2)推理判断题。根据第一段Aron took photos of his bad situation (which was going to get a lot worse) as he waited for rescue teams (救援队) to come to remove the rock so that he could get out and home safe. (阿伦拍下了他糟糕的情况,情况会变得更糟,他等待救援队来移走岩石,这样他就可以安全回家了。)可推知,阿伦拍下自己的情况,发给了救援队,有助于他们来营救。故选A。
(3)词句猜测题。根据第二段Aron cut the lower part of his arm off,having to wrench (扭动) his forearm against the big stone to break the bones,and then got himself down to the bottom of the valley,where he would begin to walk and search for help.Luckily,help arrived in the form of a helicopter(直升机) that spotted him,covered in blood. (阿伦切掉了他手臂的下半部分,他不得不用前臂抵住大石头来折断骨头,然后自己走到山谷的底部,在那里他开始走路并寻找帮助。幸运的是,一架直升机来了,spotted 浑身是血的他。)可知,阿伦从出事地点下来,走到谷底寻求帮助,被直升机发现,spotted在此处为"发现",与Found意思相近。A.Greeted问候;B.Found发现;C.Encouraged鼓励;D.Caught抓住。故选B。
(4)推理判断题。根据第一段Aron took photos of his bad situation (which was going to get a lot worse) as he waited for rescue teams (救援队) to come to remove the rock so that he could get out and home safe. (阿伦拍下了他糟糕的情况,情况会变得更糟,他等待救援队来移走岩石,这样他就可以安全回家了。)以及第二段He made what must have been one of the most difficult decisions of his life:to cut his own arm in order to survive. (他做出了一生中最艰难的决定之一:为了生存,他割开了自己的手臂。)以及Aron had tied off the wound to keep himself from bleeding to death pretty successfully and would eventually make it out alive. (阿伦成功地把伤口绑了起来,使自己不至于失血过多而死,最终他活了出来)可推知:阿伦是一个冷静且果断的人,出了事故也能冷静自救,所以他能幸存下来。故选D。
