Tan Yunxian (1461 — 1554) was a Chinese physician who learned her skills from her grandparents. Chinese women at the time could not serve apprenticeships (学徒期) with doctors. However, Tan passed the official exam. Tan treated women from all walks of life. In 1511, Tan wrote a book, Sayings of a Female Doctor, describing her life as a physician.

上面一段摘自2023年高考英语（老高考）全国卷1的阅读理解A。

我对最后一句中的describing her life as a physician 有疑问：her life 怎么会是 a physician 呢？“她的生活”应该是与“医生的生活”相比较吧！从逻辑上看，是不是应该改成：

describing her life as that of a physician

或：describing her as a physician

请教各位专家老师，谢谢！
