单选题{{B}}Text 2{{/B}} Drunken driving—sometimes called America's socially accepted form of murder—as become a national epidemic. Every hour of every day about three Americans on average are killed by drunken drivers, adding up to an incredible 250,000 over the past decade. A drunken driver is usually defined as one with a 0.10 blood alcohol content or roughly three beers, glasses of wine or several small glasses of whisky drunk within two hours. Heavy drinking used to be an acceptable part of the American manly image mid judges were not severe in most courts, but the deaths caused by drunken driving have recently caused so many well-publicized tragedies, especially involving young children, that public opinion is no longer so tolerant. Twenty states have raised the legal drinking age to 21, changing a trend in the 1960s to reduce it to 18. After New Jersey lowered it to 18,the number of people killed by 18-20 year-old drivers more than doubled, so the state recently upped it back to 21. Reformers, however, fear that raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop" responsible attitudes" about drinking and teach them to resist peer pressure to drink. Tough new laws have led to increased arrests and tests and, in many areas already, to a marked decline in number of death. Some states are also punishing bars for serving customers too many drinks. A bar or pub in Massachusetts was fined for serving six or more brandies to a customer who was" obviously drunk" and later drove off the road, killing a nine-year-old boy. As the deaths caused by accidents continue to occur daily in every state, some Americans are even beginning to speak well of the 13 years of national prohibition of alcohol that began in 1919, what President Hoover called the" noble experiment". They forget that legal prohibition didn't stop drinking, but encouraged political corruption and organized crime. As the drug trade is increasing generally, there is no easy solution.

单选题Flying over a desert area in an airplane, two scientists looked down with trained eyes at trees and bushes. After an hour"s flight, one of the scientists wrote in his book, "Look here for probable metal." Scientists in another airplane, flying over a mountain area, sent a message to other scientists on the ground, "Gold possible." Walking across hilly ground, four scientists reported, "This ground should be searched for metal." From an airplane over a hilly wasteland a scientist sent back by radio one word: "Uranium." None of the scientists had X-ray eyes: they had no magic power of looking down below the earth"s surface. They were merely putting to use one of the newest methods of locating minerals in the ground——trees and plants as signs that certain minerals may lie beneath the ground on which the trees and plants are growing. This newest method of searching for minerals is based on the fact that minerals deep in the earth may affect the kind of bushes and trees that grow in the surface. At Watson Bar Greek, a brook (小溪) six thousand feet high in the mountains of British Columbia, Canada, a mineral search group gathered bags of tree seeds. Boxes were filled with small branches from the trees. Roots were dug and put into boxes. Each bag and box was carefully marked. In a scientific laboratory, the parts of the forest trees were burned to ashes and tested. Each small part was examined to learn whether there were minerals in it. Study of the roots, branches, and seeds showed no silver. But there were small amounts of gold in the roots and a little less gold in the branches and seeds. The seeds growing nearest to the tree trunks had more gold than those growing on the ends of the branches.
