Ⅲ．阅读理解(共4小题；每小题2.5分，满分10分) This past January，Captain Preet Chandi set foot on a historic，though decidedly icy trail by becoming the first woman of color to reach the South Pole alone，without assistance．While others might have been content to make history with this singular accomplishment，“Polar Preet” Chandi is not one to rest on her achievements．The journey to the South Pole was merely “phase one” of a larger and even more extraordinary goal for the adventurous British Army officer． 课时提升作业 Period 4　课时学案 单元语法讲练(Grammar and usage) 课时提升作业 For “phase two”，the 33-year-old has set her

14，Chandi departed from Hercules Inlet，an ice-filled bay at the southwestern section of the Filchner-Ronne Ice Shelf bordering the Weddell Sea in Antarctica．Her goal is to reach Reedy Glacier within 75 days，a coast-to-coast journey consisting of roughly 1，100 miles．And “roughly” is the key word here—she'll be pulling a sled (雪橇) with equipment，weighing about 264 pounds altogether，and she'll be doing so in temperatures that can sink to minus 58 degrees Fahrenheit，with wind speeds of up to 60 miles per hour． 课时提升作业 Period 4　课时学案 单元语法讲练(Grammar and usage) 课时提升作业 Her journey thus far required years of training．Prior to her 700-mile South Pole journey，she prepared by attending a polar survival course in Norway．She continued her training back home in the UK by dragging tires，the closest thing to pulling a sled，and a month-long practise run in Greenland．Ultimately，Chandi went on to finish her first South Pole expedition in 40 days，a full eight days ahead of schedule． 课时提升作业 Period 4　课时学案 单元语法讲练(Grammar and usage) 课时提升作业 When not otherwise setting records of human endurance in extreme conditions，Chandi tries to inspire others in her day-to-day work． Chandi will be posting interval (间隔) voice blog updates of her phase two progress on her website，polarpreet．com，where a live tracking map will also provide her current location at every point along her journey． “Nothing is impossible．I've always had this idea that I can achieve something great，something that allows me to be a role model，” Chandi shared on her blog． 课时提升作业 Period 4　课时学案 单元语法讲练(Grammar and usage) 课时提升作业
