Question

急求各位英语高手帮我解答下这几句英语

我现在正在学新概念第二册，43课有一句有一句不明白现在请教下大家。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这句话是说，美国探险家R.E.伯德在飞越北极3年之后，于1929年第一次飞越了南极。大家有没有发现这句话顺序有点颠倒啊！！！美国探险家R.E.伯德在飞越北极3年之后应该这样书才对啊！！！the American explorer, R.E. Byrd after his flight over the North Po three years 于1929年第一次飞越了南极 successfully flew over the South Pole for the first time In 1929才对啊！！！至少我认为应该是这样不知道书中这样写又怎么解释感觉顺序真的是颠倒啊！！！

Answer 1

three years after his flight over the North Pole 是插入语啊，修饰1929的

这里虽然强调的是1929年首次飞越南极的壮举，但也顺便提及了他1926年飞越北极的事迹

英语中很多插入语的，这是中文里不常见的

Answer 2

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.
句子的中心是In 1929，R.E. Byrd, successfully flew over the South Pole for the first time.
three years after his flight over the North Pole, the American explorer,为插入成分。
