单选题 Resistance to the 1954 United States Supreme Court decision terminating segregation placed the schools in the middle of a bitter and sometimes violent dispute. By 1965, when a measure of genuine integration had become a reality in many school districts, tile schools again found themselves in the eye of a stormy controversy. This time the question was not which children were going to what schools but what kind of education society should provide for the students. The goal of high academic performance, which had been revived by criticisms and reforms of the 1950s and early 1960s, began to be challenged by demands for more liberal and free schooling. Many university and some high-school students from all ethnic groups and classes had been growing more and more frustrated--some of them desperately so--over what they felt was a cruel and senseless war in Vietnam and a cruel, discriminatory, competitive, loveless society at home. They demanded curriculum reform, improved teaching methods, and greater stress and action on such problems as overpopulation, pollution, international strife, deadly weaponry, and discrimination. Pressure for reform came not only from students but also from many educators. While students and educators alike spoke of the greater need for what was taught, opinions as to what was relevant varied greatly. The blacks wanted new textbooks in which their people were recognized and fairly represented, and some of them wanted courses in black studies. They, and many white educators, also objected to culturally biased intelligence and aptitude tests and to academic college entrance standards and examinations. Such tests, they said, did not take into account the diverse backgrounds of students who belonged to ethnic minorities and whose culture was therefore different from that of the white middle-class student. Whites and blacks alike also wanted a curriculum that touched more closely on contemporary social problems and teaching methods that recognized their existence as individual human beings rather than as faceless robots competing for grades. Alarmed by the helplessness and hopelessness of the urban ghetto schools, educators began to insist on curricula and teaching methods flexible enough to provide for differences in students' social and ethnic backgrounds. Moreover, for educational reformers the urban ghetto school became a symbol of a general failure of American education to accomplish the goal of individual development. Also reminiscent of those decades were the child-centered schools that sprang up in the later 1960s as alternatives to and examples for tile traditional schools. The clash between the academically and the humanistically oriented schools of thought, therefore, was in many ways one more encounter in the continuing battle between conservative and liberals.

单选题{{B}}Passage 1{{/B}} "Dimpy," as her friends call her, heard about the hazards of smoking in health class. "They showed pictures of lungs of people who smoked. It was gross," says the petite 14-year-old. Yet, as she shops along the Third Street Promenade in Santa Monica, Calif. , the ninth grader points out all the places where she regularly buys cigarettes without hassle. "All my friends smoke," She shrugs, explaining the habit she developed in the sixth grade. "Once they pressure you, you start. And it's kind of hard to stop. " As the cigarette industry draws increasing fire, teen smokers like Dimpy are becoming the focus of concerned policy makers around the country. Supported by a University of Michigan study showing a dramatic rise in adolescent tobacco use, the White House is considering ways to curb the surge. Among the options: eliminating cigarette vending machines, restricting tobacco advertising, increasing the federal excise tax on cigarettes and launching a national media campaign directed at adolescents. A grand jury in New York has begun an investigation to determine whether Philip Moms Cos. concealed information linking nicotine levels and addictiveness. And the Justice Department is looking into whether tobacco company executives committed perjury in their April 1994 congressional testimony on how smoking affects health. Lack of credibility. But it's tough to get an antismoking message through to teens. The California Department of Health Service spends $12 million a year placing antismoking commercials on television, including popular MTV programs, but many teenagers aren't buying the message. Says Erica leona, who will enter eighth grade in the fail, "I don't think those ads work, because It's like a cartoon, it's too exaggerated. " In fact, teens seem skeptical about the potential effectiveness of any organized efforts to reduce smoking, like increasing taxes. While research shows that every time taxes go up, sales go down, including among teens, young people say the cost is relatively low in comparison with.other vices. "You want weed, it'll cost you," says Robert Caldwell, 14. "For cigarettes, you just go anywhere, put 12 quarters into one of those machines, take it and go. " Other teens maintain that eliminating vending machines won't make cigarettes any harder to buy. "You give a guy enough to buy you a pack and a beer, and he'll buy the pack," says Cameron Davis, 13. And advertising isn't really what entices adolescents to smoke. For the most part, they say, teens smoke because of peer pressure. "It's like sex. " says 13-year-old Frances, who started smoking at age 9. "You feel like, if you don't do it with your boyfriend, he won't like you. " In addition, messages that relate to health don't compute with adolescents, who often feel invincible. It doesn't help, says Roxanne Cannon, editorial director of Teen and Sassy magazines, that so many teen idols such as Ethan Hawke, Jason Priestley and Luke Perry are seen smoking. Teens say any message is more effective if it's communicated by Other kids. But eyen a White House appeal made by Chelsea Clinton might not get through to adolescents eager to smoke. "I don't listen to my morn when she tells me to stop," says Dimpy. "Why would I listen to anyone else."
