In 1929, three years after his flight over theNorth Pole, the American explorer, R.E. Byrd, successfully flew over the SouthPole for the first time. Though, at first, Byrd and his men were able to take agreat many photographs of the mountains that lay below, they soon ran intoserious trouble. At one point, it seemed certain that their plane would crash.It could only get over the mountains if it rose to 10,000 feet. Byrd at onceordered his men to throw out two heavy food sacks. The plane was then able torise and it cleared the mountains by 400 feet. Byrd now knew that he would beable to reach the South Pole which was 300 miles away, for there were no moremountains in sight. The aircraft was able to fly over the endless white plainswithout difficulty.

任务配置：L0+L4
笔记：
1.知识点
（1）for the first time 表示“第一次”，time在这里表示“次”、“回”，还可以说this time， last time， next time， another time， each time， for the last time等
（2）run into trouble的含义与 get into trouble相似，表示“陷入困境”
（3）At one point， it seemed certain that their plane would crash.在有个地方，飞机似乎肯定要坠毁了。
at one point在此处可以解释为“在有个地方”，但它通常的含义为“在某一时刻”，point指时间上的某一点：At one point， he made up his mind to become a painter. 他曾一度下决心要当个画家。
（4）… it cleared the mountains by 400 feet.……它在离山头400英尺的高度飞越了过去。
clear在这里表示“(不接触地)越过”：He cleared 2. 10 metres.他跳过了2.10米。
by表示“以……之差”：I missed the train by ten minutes. 我晚了10分钟，没赶上火车。
练习感悟：
本篇的长句比较多，第一遍听的时候没能完全听懂。类似at one point、clear的意思不懂，也导致理解有差异。自己也有点畏难情绪，因为本篇的内容不是常见的内容，所以一开始就觉得很难，觉得自己不会。
