解题思路: 石油的搜寻
解题过程:
钻井工是油田的老大。他是一个熟练技术工人。有时他得把钻头
超过地下一英里深。钻探过程中可能会突然碰上在巨大的压力天然气和石油, 如果他油气突然喷出来并着着火,油井便可能永远无法启用。这种危险是人人共知的,因此人们总是采取防护措施来防止这种事的发生。
在开采石油时有很好的运气。可能钻头正好错过了虽然它离它很近的石油; 另一方面,它可能穿过石油到更深的地方了。当钻头钻到下面, 它带上来了土壤。土壤是检查油痕迹的。钻探石油的人如果对这个地方失望了就会到另一个地方去。政府花了大量的钱, 例如,埃及的沙漠中,在石油的“搜索”上。有时候几乎就找不到。当我们为我们的汽车买些汽油, 我们付的不仅仅是汽油,但成本也的一部分费用也有寻找石油的花费上。
52. B drilling石油的搜寻
53. C 搜寻石油失败的费用也包含在汽油的的价格中,由买汽油的人支付
54.A 钻头带上来的泥土可以用来检测是否此处有石油
55. C钻探过程中可能会突然碰上在巨大的压力天然气和石油, 如果他油气突然喷出来并着着火,油井便可能永远无法启用。
最终答案:略
