二、重点句型
1. 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.
（1）句子的主句是 the American explorer flew over the South Pole.
（2）本句中有两对同位语，three years after... 是 1929 的同位语，插入性地补充说明他飞越北极的经历；R. E. Byrd 是 the American explorer 的同位语。
2. 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.
（1）连词 though 引导的是让步状语从句，意为 “虽然…”。从句里的时间状语 at first 是用逗号隔开的。
（2）were able to 是暗示这件事不仅能做而且做成了。
（3）that lay below 是定语从句，修饰山脉，lay 是 lie 的过去式。
Beauty lies in the eyes of the beholder. 情人眼里出西施。
The wonder of life lies in its colorfulness. 生活的美妙在于它的丰富多彩。
（4）take a photograph of 拍照
run into trouble 陷入困境
练习：在他离家之前，他给他的旧房子拍了张照片。
Before he left, he took a photograph of his old house.
练习：每次他遇到困难，他都向父母寻求帮助。
He always asks his parents for help when he runs into trouble.
3. At one point, it seemed certain that their plane would crash.
It seemed certain 意思是 “看起来似乎是确定的”。It 是形式主语，真正的主语是 that 引导的主语从句。
练习：他曾一度决定要当个画家。
It seemed certain that he decide to be an artist.
练习：现在似乎肯定会议将会被推迟。
Now it seems certain that the meeting will be put off.
4. It could only get over the mountains if it rose to 10, 000 feet.
非真实条件句，表提前的假设。
5. 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.
for 引导原因，表达了他们是由主观推测得出结论的。for 不可放句首，先有结果，再用 for 引出原因。
6. The aircraft was able to fly over the endless white plains without difficulty.
without difficulty 是介词短语作方式状语，意思是 “毫无困难地”，用来修饰动词 “飞越”。
