In 1929, three years after his flight over the No

In 1929, three years after his flight over the North Pole, the American explorer, R. E. Byrd, successfully flew over the South Pole for the first time.我想问一下，这句话中的 his 是什么意思？

his代指的是这个句子之前的人的，意思是他的。In 1929， three years after his flight over the North Pole大意就是：在1929年，也就是他飞过北极的三年之后。

穿越北极的飞行

flight 飞行 over 在。。。上空 the north pole 北极

after是介词   his flight over the north pole是名词短语   而介词后面只能加短语成分 你的这个题目不完整 我个人觉得应该是时间状语成分 three year开始到pole。因为我没有看见你后面半句题目   暂时先分析到这
