  新概念英语第二册第四十三课课文解析

  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.

  美国探险家 R・E・伯德在飞越北极3年之后,于1929年第1次飞越了南极。

  (1)这句话包含两个同位语。three years after… 为1929的同位语,作插入性的补充说明;R.E.Byrd 作 the American explorer 的同位语。

  (2)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:

  I remind you for the last time that if you don't hurry, you'll miss the train.

  我最后一次提醒你,如果不快点,你会误了火车的。

  Give him these photos next time you see him.

  下次你见到他时把这些相片给他。

  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.

  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。

  (1)连词though引导的是让步状语从句,其含义为“虽然……”、“尽管……”。这个从句中的时间状语at first被单独用逗号隔开了,它如果按正常的词序应放在从句的末尾,但有可能会引起误解。

  (2)at first与主句中的 soon形成时间上的照应,表示先后次序。

  (3)take a photograph of 表示“拍……的照片”:

  He took a photograph of his house before he left home.

  他离家前给他家的房子拍了一张照片。

  (4)that lay below为 the mountains的定语从句,that为从句的主语。

  (5)run into trouble的含义与 get into trouble相似,表示“陷入困境”:

  Each time he ran into trouble, he asked his parents for help.

  每当他陷入困境时,他都向他父母求助。

  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。

  (1)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。

  (2)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:

  It now looks certain that the meeting is going to be put off.

  现在似乎可以肯定会议将被推迟。

  4.rise to

  (飞机)上升至

  5.… 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。

  He is younger than me by two years.

  他比我小两岁。
