L16 The Search for the Earth's Minerals

The deepest holes of all are made for oil,and they go down to as much as 25,000 feet. But we do not need to send men down to get the oil out, as we must with other mineral deposits. The holes are only borings, less than a foot in diameter. My particular experience is largely in oil, and the search for oil has done more to improve deep drilling than any other mining activity. When it has been decided where we are going to drill, we put up at the surface an oil derrick. It has to be tall because it is like a giant block and tackle, and we have to lower into the ground and haul out of th. ground great lengths of drill pipe which are rotated by an engine at the top and are fitted with a cutting bit at the bottom.
The geologist needs to know what rocks the drill has reached, so every so often a sample is obtained with a coring bit. It cuts a clean cylinder of rock, from which can be seen he strata the drill has been cutting through. Once we get down to the oil,it usually flows to the surface because great pressure, either from gas or water,is pushing it. This pressure must be under control,and we control it by means of the mud which we circulate down the drill pipe. We endeavour to avoid the old, romantic idea of a gusher, which wastes oil and gas. We want it to stay down the hole until we can lead it off in a controlled manner.

 

新东方新概念英语第四册课堂笔记:第16课的延伸阅读——新概念学习方法手册

 

  1、先整体听一遍课文。看看自己到底能听懂多少。

  2、利用复读机复读功能,逐句播放,听一句,写一句,碰到不会的单词了就先空着。继续往下听写。整篇课文或者你拟定的几句话都听写完了,再结合上下文看看那些不会的单词能不能猜出来。

  3、逐句回放那些空着单词的句子,试一试能不能写出来。如果还不行,就打开书对照的看一下。在这里,我倒是不主张钻牛角尖,恨不能一个不会的单词憋好几年才写出来。因为,有些单词确实我们不会,那么直接看一下书,就知道了,下次也可能在其他课文中还会遇到,这就等于是复习了,不要太死板了。其实,这次看了,未必下次你真的就会写。

  4、把不会的单词,或者你认为含糊的单词去逐个的查词典,逐条的去看注解。

  5、每天多听这些听写过的录音,最起码你要在今天听写新内容之前要默写一遍昨天听写过的。

  6、看着中文注解写英文,联系中英互换。绝对有效。

  7、如果你想练就口语,就要大声的去模仿朗读,最好能背读。

  8、运用李阳的“一口气”训练你的伶牙俐齿,这个真是很管用,以后你会发现听任何英语都不会觉得语速快的。
