郑多燕小红帽反弹吗:新概念英语第二册-Lesson 43

第一部分 TEXT

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. 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. 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 once ordered his men to throw out two heavy food sacks. The plane was then able to rise and it cleared the mountains by 400 feet. 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. The aircraft was able to fly over the endless white plains without difficulty.

参考译文

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. 虽然开始时伯德和他的助手们拍下了飞机下面连绵群山的大量照片， 但他们很快就陷入了困境. 在有个地方， 飞机似乎肯定要坠毁了. 只有在飞至10，000英尺的高度时， 它才能飞过这些山头. 伯德马上命令他的助手们把两个沉重的食物袋扔掉， 于是飞机可以上升了， 它在离山头400英尺的高度飞越了过去. 伯德这时知道他能够顺利飞抵300英里以外的南极了， 因为前面再没有山了. 飞机可以毫无困难地飞过这片茫茫无际的白色原野!

第三部分 LANGUAGE POINTS

1、In 1929， the American explorer， R.E. Byrd， successfully flew over the South Pole for the first time.
for the first time:第1次

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.
Though:虽然，连词引导让步状语从句，注意该句式中，用了though，则主句不能用but开头
a great many:大量的，很多的
that lay below：定语从句修饰mountains
run into trouble:碰上麻烦

3、At one point， it seemed certain that their plane would crash.
at one point:在某一时刻
it seemed certain that：看起来肯定...
seem的常见用法：
① seem + as if
② seem + adj.
③ seem to be
④ seem that...
注意：
it为“先行主语”，真正的主语为that引导的从句。it作先行主语时经常与seem，appear，look等连用
4、It could only get over the mountains if it rose to 10，000 feet.
feet:英尺，是foot的复数形式
get over the mountains：飞越这些山
only...if...:只有...才...；不...除非...

5、The plane was then able to rise and it cleared the mountains by 400 feet.
比较：
over 越过
clear 越过， 跳过，没有接触面的飞跃
go over 飞跃

by:（表示数量、程度等）以...之差
