一个很难的英语句子的翻译-------------务必高手帮忙
Doctor are known to be terrible pilots. They don’t listen because they already know it all. I was lucky：【I became a pilot in 1970, almost ten years before I graduated from medical school】. I didn’t realize then, but becoming a pilot makes me a better surgeon. I loved flying. As I flew bigger, faster planes, and in worse weather. I learned about crew resource management（机组资源管理）, or CRM, a new idea to make flying safer. It means that crew members should listen and speak up for a good result, regardless of positions.
请解释【】里的句子,我记得：时间段+ before ,翻译为：多长时间以后,不知道是否正确?高手详解.并标准翻译,谢谢
翻译的都这么烂.

Answer 1

【I became a pilot in 1970, almost ten years before I graduated from medical school】.
1970【我成为了一名飞行员,几乎十年前我从医学院毕业】.
