(2025年真题·阅读理解A篇第33题) The 32-year-old woman was born into a family of farmers in a mountainous area of Africa. The family was so poor that they didn’t even have running water. As a kid, Molly never thought that the mountains around her village were within reach. In her culture, women are expected to follow the local tradition. But Molly decided early that this path wasn’t for her. She broke from tradition by moving to the capital city at the age of 16 to stay with her relatives. There, she graduated from middle school, took out a student loan, and went to college. She studied communications and later started her career as a reporter. Breaking from tradition was no easy task, but Molly took a step further. While reporting on a mountain-climbing event in Asia, she became seriously interested in this sport. Although she had good physical condition, she lacked experience in professional mountain climbing. After training with professionals for several years, she became a full-time climber. In the seven years since, she has reached the top of three 8,000-meter mountains. Which is the correct order of Molly's life experiences? ① going to college ② training with professionals ③ becoming a reporter ④ climbing 8000-meter mountains A. ①→③→④→② B. ①→③→②→④ C. ③→②→①→④ D. ③→①→④→② 【答案】B 【详解】考查序数概念在排序题中的应用。根据文章描述，Molly 先上中学、贷款上大学（①），毕业后成为记者（③），在报道登山活动时对登山产生兴趣，经过专业训练（②），最后成为全职登山者并登顶三座8000米高山（④）。正确顺序为①→③→②→④。 【命题思路剖析】 核心考点：利用时间顺序和序数逻辑进行事件排序。 命题逻辑：排序题本质是考查学生对事件发生先后顺序的理解，需要运用序数思维。 考情指向：阅读理解中常见的排序题，虽然没有直接出现first, second等词，但要求考生建立逻辑顺序。 4.
