Mara had anticipated（预见）/æn'tisipeit/ rain on the southern（南方的）/ˈsəðərn/ path（小路）/pɑːθ/ of Ridge Nine, but the snowy（下雪的）/snoʊi/ mist（雾）/mist/ was more dramatic（猛烈的）/drә'mætik/ than expected. The mountain chain（山脉）/tʃein/ disappeared beneath cloud, and exposure（受寒）/ik'spәuʒә/ to cold began to threaten（恐吓）/'θretn/ the group. Fortunately（幸运地）/'fɒitʃәnitli/, their living（生活）/'liviŋ/ guide had marked every direction（说明）/dəˈrekʃnz/. A mild（温和的）/maild/ breeze became an intense wind, and frightened（受惊吓的）/'frait(ә)nd/ hikers could barely grasp（抓住）/græsp/ the rope around each pack.
The weather unit indicated（指）/ˈɪndəˌkeɪt/ a pressure gap（缝隙）/gæp/ near the peak（山峰）/pi:k/. To the northeast（东北）/.nɒ:θ'i:st/, sunlight（日光）/'sʌnlait/ faded（淡入）/feid/ behind a steep（浸渍）/sti:p/ wall; to the northwest（西北）/.nɒ:θ'west/, dark cloud surrounded the telescope（望远镜）/'teliskәup/ station. Mara used a rubber（橡胶的）/ˈrəbər/ cover to protect the screen and checked the extent of the storm. A collision（碰撞）/kә'liʒәn/ with loose rock had injured one hiker's breast（胸部）/brest/ and shoulder, though no bone appeared broken.
Luis examined the path toward the shelter（庇护所）/'ʃeltә/. 男“The southeast（东南）/sauθ'i:st/ route is horrible（可怕的）/'hɒrәbl/ but logical（合乎逻辑的）/'lɒdʒikәl/. The southwest（西南）/sauθ'west/ trail crosses the jungle（丛林）/'dʒʌŋgl/ and may trap us.” They chose the safer direction and tied a chain between the strongest walkers. Besides（此外）/ˌbiˈsaɪdz/ the first-aid sheet（床单）/ʃi:t/, each person carried warm clothing（衣服）/'klәuðiŋ/ and a signal light.
A strange mushroom（蘑菇形物）/'mʌʃrum/ stood beside the route, but nobody touched it. The group passed an old volcano（火山）/vɒl'keinәu/ rock and a rare（稀罕的）/rєә/ weather instrument that seemed to orbit（轨道）/'ɒ:bit/ in the wind. Mara mostly（大部份）/'mәustli/ focused on skin（皮肤）/skɪn/ colour, breathing, and signs of shock. One hiker began to struggle（斗争）/'strʌgl/, so they reduced speed. The rescue（援救）/'reskju:/ shelter finally emerged beyond an outer（外部的）/'autә/ ridge, small but splendidly solid.
Inside, they treated the injury and shared heat. A pregnant（怀孕的）/'pregnәnt/ hiker felt an ankle twist（一扭）/twist/ but could still move. Seven（七）/ˈsɛvən/ signals flashed from the eastern（东方的）/'i:stәn/ mount（乘骑用马）/maunt/ as a rainy（多雨的）/ˈreɪni/ dawn began to fade. A corrupt（使腐烂）/kә'rʌpt/ reading had exaggerated the temperature, yet the danger did exist（存在）/ɪgˈzɪst/. Mara could anticipate the northern（北方的）/ˈnɔrðərn/ rescue signal, and the display did indicate their location. Rescuers had to spit（唾液）/spit/ snow from their lips and used a small flame（焚烧）/fleim/ to reveal each organ（风琴）/'ɒ:gәn/'s response to cold. The shelter looked splendid（光亮的）/'spendid/ in the surrounding（环境）/sә'raundiŋ/ white. The adventure became a lesson in caution（小心）/'kɒ:ʃәn/: safety depends on current evidence, clear roles, and courage to turn back. At the station, Mara filed a route report and replaced the faulty sensor. The next group would receive the corrected warning before leaving the valley.
