【正确答案】 C
【答案解析】[听力原文] It's no secret that any type of tobacco use is not healthy. But, for most people, it's hard to quit. That's because most of them started the habit as teenagers and because tobacco contains nicotine. 'Nicotine is a highly addictive, very powerful drug; teens are likely to use more than one form of tobacco. It could be cigarettes, small cigars, smokeless tobacco. And teens who smoke are likely to use electronic cigarettes, which also deliver nicotine. The more nicotine that you get, the more addicted you are, the more difficult it is for you to quit. ' said Dr. Kimberly Horn. There is no one technique for quitting that works for everyone. Some turn to e-cigarettes for help. Cici is hoping electronic cigarettes can help her kick the habit. She said, 'After many years of smoking. I really don't like the smell of smoke. I don't like the taste it leaves in my mouth. And I don't like the fact that other people are going to be bothered by the tobacco smoke. ' Studies show electronic devices can work for some people, but not for others. Behavioral therapy and medicine, gum and nicotine patches that reduce nicotine cravings might help. Dr. Nancy and other researchers designed a program to help smokers quit while they were in the hospital and stay smoke free after they were discharged. Patients were given a nicotine patch and advice in the hospital, with follow-up support after they left. 'We know that medication works and that advice works, but they both together work much better than either one alone, ' Nancy said. Seventy percent of smokers in that program were still smoke-free six months after leaving the hospital. The U. S. government and private organizations have been running anti-smoking campaigns since 1964. A study from the Yale School of Public Health found that those who quit during this time period had a 30-percent improvement in the expectation of life. What does Dr. Kimberly Horn think of smoking? 题干中的Dr. Kimberly Horn为听力关键词,听力原文中Dr. Kimberly Horn 说到The more nicotine that you get,the more addicted you are,the more difficult it is for you to quit. 可见,Kimberly Horn医生认为:吸入体内的尼古丁越多,烟瘾越大,就越难戒掉。故选项C为答案。其他选项均与Kimberly Horn所说内容不符,排除。
