[单项选择]Questions 49 to 52 are based on the following passage:
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 Samuel M. Kier, a manufacturer in western Pennsylvania, began collecting the oil from local seepage 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 Ei. Drake, a retired railroad conductor. 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.

C. To describe the mood when oil was first discovered

[单项选择]
I hear many parents complaining that their teenage children are rebelling. I wish it were so. At your age you ought to be growing away from your parents. You should be learning to stand on your own two feet. But take a good look at the present rebellion. It seems that teenagers are all taking the same way of showing that they disagree with their parents. Instead of striking out boldly on their own, most of them are clutching at (attempting to seize) one another’s hands for reassurance.
They claim they want to dress as they please. But they all wear the same clothes. They set off in new directions in music. But somehow they all end up crowded round listening to the same record. Their reason for thinking or acting in thus—and—such a way is that the crowd is doing it. They have come out of their cocoons(蚕茧) into a larger cocoon.
It has become harder and harder for a teenager to stand up against the popularity wave and to go his or her own way. Indus
A. convincing
B. instructive
C. influential
D. authoritative
