Nicotine (尼古丁) patches axe small, nicotine-containing adhesive (黏着性的) discs applied to the skin. The nicotine is slowly absorbed through the skin and enters the bloodstream. Over time, the nicotine dose is reduced and eventually the desire for nicotine is eased. Nicotine gum works in a similar manner, providing small doses of nicotine when chewed. The benefits of giving up smoking include the immediate reduction of harm to the health of the smoking and easily admission to social activities and institutions that ban smoking. In a 1988 report, the US Surgeon General declared cigarette smoking to be more harmful and expensive than the use of cocaine (可卡因), alcohol, or heroin. Recent evidence supports this claim. The United States government has collected a special tax on cigarettes for several decades. The rate rose from 8 cents per pack of 20 cigarettes in 1951 to 24 cents per pack in 1993. In other developed countries, the cigarette tax rate is much higher, ranging from 50 percent in Switzerland to 85 percent in Denmark. In the United States, the first direct action to check smoking was the regulation of a warming on cigarette packages by the Federal Trade Commission. This warning took effect in 1964 and was strengthened in 1969 to read: "Warning: The Surgeon General Has Determined That Cigarette Smoking Is Dangerous to Your Health." In 1971 all cigarette advertising was banned from radio and television, and cities and states passed laws requiring nonsmoking sections in public places and workplaces.

单选题Natural Medicine Since earliest days, humans have used some kinds of medicines. We know this because humans have survived. Ancient treatments for injury and disease were successful enough to keep humans from dying out completely. They were successful long before the time of modem medicine. Before the time of doctors with white coats and shiny (发亮的) instruments. Before the time of big hospitals with strange and wonderful equipment. Many parts of the world still do not have university-educated doctors. Nor do they have expensive hospitals. Yet injuries are treated. And diseases are often cured, how? By ancient methods. By medicines that might seem mysterious, even magical (有魔力的). Traditional medicines are neither mysterious nor magical, however. Through the centuries, tribal (部落的) medicine men experimented with plants. They found many useful chemicals in the plants. And scientists believe many of these traditional medicines may provide the cure for some of today"s most serious diseases. Experts say almost 80% of the people in the world use plants for health care. These natural medicines are used not just because people have no other form of treatment. They are used because people trust them. In developed areas, few people think about the source of the medicines they buy in a store. Yet many widely-used medicines are from ancient sources, especially plants. Some experts say more than 25 % of modern medicines come, in one way or another, from nature. Scientists have long known that nature is really a chemical factory. All living things contain chemicals that help them survive. So scientists" interest in traditional medicine is not new. But it has become an urgent concern. This is because the earth"s supply of natural medicines may be dropping rapidly.
