问题     An important new industry, oil refining, grew after the Civil War. Crude oil, or petroleum a dark, thick ooze from the earth had been known for hundreds of years, but little use had ever been made of it. In the 1850’s Samud M. Kier, a manufacturer in western Pennsylvania, began collecting the oil from local scapages and refining it into kerosene. Refining, like smelting, is a process of removing impurities from a raw material.
    Kerosene was used to light lamps. It was a cheap substitute for whale oil, which was becoming harder to get. Soon there was a large demand for kerosene. People began to search for new supplies of petroleum.
    The first oil well was drilled by E.L. Drake. In 1859 he began drilling in Titusville, Pennsylvania. The whole venture seemed so impractical and foolish that onlookers called it "Drake’s Folly". But when he had drilled down about 70 feet (21) meters, Drake struck oil. His well began to yield 20 barrels of crude oil a day.
    News of Drake’s success brought oil prospectors to the scene. By the early 1860’s these wildcatters were drilling for "black gold" all over western Pennsylvania. The boom rivaled the California gold rush of 1848 in its excitement and Wild West atmosphere. And it brought far more wealth to the prospectors than any gold rush.
    Crude oil could be refined into many products.  For some years kerosene continued to be the principal one. It was sold in grocery stores and door-to-door. In the 1880’s and 1890’s refiners learned how to make other petroleum products such as waxes and lubricating oils. Petroleum was net then used to make gasoline or heating oil. [br] Why does the author mention the California gold rush?
选项 A、To explain the need for an increased supply of gold.
B、To indicate the extent of United States mineral wealth.
C、To describe the mood when oil was first discovered.
D、To argue that gold was more valuable than oil.
答案 C
解析 文章第四段中The boom rivaled the California gold rush of 1848 in its excitement and Wild West atmosphere．提到了“淘金热”。仔细阅读前后的句子，我们可以得出结论：这里是把“淘金热”和发现石油的狂热加以对比。而在四个选项中，只有c在意思和观点上与原文相一致。故本题的正确答案是C。
