1929 年，在飞越北极三年后，美国探险家 R.E. 伯德成功地首次飞越了南极。
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.
尽管起初伯德和他的队员们能够拍下下方山脉的大量照片，但他们很快就遇到了严重的麻烦。
Though, at first, Byrd and his men were able to take a great many photographs of the mountains that lay below, they soon ran into serious trouble.
在某一时刻，似乎可以肯定他们的飞机将要坠毁。
At one point, it seemed certain that their plane would crash.
只有飞到一万英尺的高度，飞机才能越过那些山脉。
It could only get over the mountains if it rose to 10,000 feet.
伯德立刻命令他的队员扔出两个沉重的食物袋。
Byrd at once ordered his men to throw out two heavy food sacks.
飞机随后得以爬升，并以400英尺的余量飞越了山峰。
The plane was then able to rise and it cleared the mountains by 400 feet.
伯德此时已经知道，他将能够到达南极点——那里距此还有300英里远——因为视野内再没有更多的山脉了。
Byrd now knew that he would be able to reach the South Pole which was 300 miles away, for there were no more mountains in sight.
飞机得以毫无困难地飞越那片无尽的白色平原。
The aircraft was able to fly over the endless white plains without difficulty.
