Lesson 13-1 The search for oil
The deepest holes of all made for oil, and they go down to as much as 25,0000 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 the 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.

练习感悟：
今天是课文前半部分，生词不多。熟词生义有：strikt作动词，有“发现（矿物，石油等）”意思。boring作名词，有“钻孔”的意思。lower还可以作动词，有“将……放下，降下”的意思。另外，要注意词组。先理解句子再读。
