单选题{{B}}第二篇{{/B}} Oil and Economy Could the bad old days of economic decline be about to return? Since OPEC agreed to supply-cuts in March, the price of crude oil has jumped to almost $ 26 a barrel, up from less than $10 last December. This near-tripling of oil prices calls up scary memories of the 1973 oil shock, when prices quadrupled, and 1979-1980, when they also almost tripled. Both previous shocks resulted in double-digit inflation and global economic decline. So where are the headlines warning of gloom and doom this time? The oil price was given another push up this week when Iraq suspended oil exports. Strengthening economic growth, at the same time as winter grips the northern hemisphere ,' could push the price higher still in the short term. Yet there are good reasons to expect the economic consequences now to be less severe than in the 1970s. In most countries the cost of crude oil now accounts for a smaller share of the price of petrol than it did in the 1970s. In Europe, taxes account for up to four-fifths of the retail price, so even quite big changes in the price of crude have a more muted effect on pump prices than in the past. Rich economies are also less dependent on oil than they were, and so less sensitive to swings in the oil price. Energy conservation, a shift to other fuels and a decline in the importance of heavy, energy-intensive industries have reduced oil consumption. Software, consultancy and mobile telephones use far less oil than steel or car production. For each dollar of GDP (inconstant prices) rich economies now use nearly 50% less oil than in 1973．The OECD estimates in its latest Economic Outlook that, if oil prices averaged $ 22 a barrel for a full year, compared with $13 in 1998, this would increase the oil import bill in rich economies by only 0.25% - 0.5% of GDP. That is less than one-quarter of the income loss in 1974 or 1980．On the other hand, oil-importing emerging economies-to which heavy industry has shifted--have become more energy-intensive, and so could be more seriously squeezed. One more reason not to lose sleep over the rise in oil prices is that, unlike the rises in the 1970s, it has not occurred against the background of general commodity-price inflation and global excess demand. A sizable portion of the world is only just emerging from economic decline. The Economist's commodity price index is broadly unchanging from a year ago. In 1973 commodity prices jumped by 70% , and in 1979 by almost 30%.

单选题Hollywood and American Movie Industry When we think of Hollywood a term I use loosely to describe American movie production in general, not simply films made in Los Angeles we think of films aimed at amusing audiences and making money for producers. During the early years of the new century, as workers won their demands for higher wages and a shorter working week, leisure assumed an increasingly important role in everyday life. Amusement parks, professional baseball games, nickelodeons (五分钱戏院), and dance halls attracted wide array of men and women anxious to spend their hard earned dollars in the pursuit of fun and relaxation. Yet of all these new cultural endeavors, films were the most important and widely attended source of amusement. For a mere five or ten cents, even the poorest worker could afford to take himself and his family to the local nickelodeon or storefront theatre. "Every little town that has never been able to afford and maintain an opera house, "observed one journalist in 1908. "now boasts one or two' Bijou Dreams'. "By 1910 the appeal of films was so great that nearly one -third of the nation flocked to the cinema each week; ten years later, weekly attendance equaled 50 per cent of the nation's population. Early films were primarily aimed at entertaining audiences, but entertainment did not always come in the form of escapist fantasies. Many of the issues that dominated Progressive - era politics were also portrayed on the screen. "Between 1900 and 1917 ,"observes Kevin Brownlow, "literally thousands of films dealt with the most pressing problems of the day—white slavery, political corruption, gangsterism (犯罪) , loansharking (高利贷), slum landlords, racial prejudice, etc. "While most of these films were produced by studios and independent companies, a significant number were made by what we might call today" special interest groups". As films quickly emerged as the nation's most popular form of mass entertainment, they attracted the attention of a wide range of organizations that recognized the medium's enormous potential for disseminating propaganda to millions of viewers.

单选题第三篇　　　　　　　　　　　　 Too Late to Regret It When I was a junior, I met a second-year student in my department. He wasn't tall or good-looking, but he was very nice, attractive and athletic. He had something that I admired very much. He was natural, warm, and sincere. I disregarded (不顾) my parents' disapproval. We were very happy together. He picked me up from my dorm every morning, and after class we would sit alongside the stream that ran through campus, or sunbathe (晒太阳) on the lawn. At night he would walk me back to my dorm. He came from a poor family, but in order to make me happy, he borrowed money from his friend to buy presents and meals for me.

Then we had a quarrel last June. He was in great pain, and my cold words and bad moods started turning him away. Graduation time was drawing near, and hometown. He said that he couldn't put up with at him in despair. He said he wanted to go back to his me anymore. I was shocked and looked. True love happens only once, but I found it out too late.

单选题In the late 1960s and early 1970s, New York legislators faced a drug problem they feared was growing out of control. Federal statistics showed as many as 559,000 users nationwide and state police saw a 31 percent increase in drug arrests by 1972. In response Gov. Nelson Rockefeller created the Narcotic Addiction and Control Commission in 1967, aimed at helping addicts get clean. After the program proved too costly and ineffective. New York launched the Methadone(美沙酮) Maintenance Program, which similarly caused little reduction in drug use. But by 1973, calls for stricter penalties had grown too loud to ignore, prompting Albany to pass legislation that created required minimum sentences of 15 years to life for possession of four ounces of narcotics—about the same as a sentence for second -degree murder. What was troubling New York in late 1960s and early 1970s according to the passage?A. There were 559,000 drug users in the state.B. There was a 31% increase in drug use by 1972.C.
