问题     Millions of teenagers are in danger of putting their health at risk by getting hooked on e-cigarettes, experts warn. Leading health researchers say they are "very concerned" by the growing number of youngsters trying the devices as a major new study reveals one in five teenagers has accessed them.
    E-cigarettes have been marketed as a healthier alternative to smoking conventional cigarettes. But previous research shows e-cigarettes generate poisonous chemicals similar to those found in tobacco and may harm the lungs and immune system.
    Worryingly, researchers at Liverpool John Moores University discovered 16% of teenagers who have used e-cigarettes had never previously smoked. The experts also found e-cigarettes were " strongly related" to drinking among teenagers. Study author Prof. Mark Bellis warned that such " rapid penetration into teenage culture of what is essentially a new drug-use option is without precedent(先例). " He added: " Our research suggests that we should be very concerned about teenagers accessing e-cigarettes. While debate on e-cigarettes has focused largely on whether or not they act as a gateway to tobacco cigarette use, e-cigarettes themselves contain a highly addictive(上瘾的)drug that may have more serious and longer lasting impacts on children because their brains are still developing. "
    Researchers surveyed 16,000 students aged 14 to 17 in the North West of England and asked them about their alcohol and tobacco use. They found that one in five answered yes to the question: " Have you ever bought or tried electronic cigarettes?" More males than females said they had, and the figure increased with age and if they lived in a deprived poor area.
    Of the teenagers that had accessed e-cigarettes, 16% had never smoked, 23% had tried smoking but did not like it, 36% were regular smokers, 12% only smoked when drinking, and 14% were ex-smokers. The research, published in journal BMC Public Health, also found teenagers who drank alcohol were significantly more likely to have accessed e-cigarettes than non-drinkers.
    Among those who had never smoked, it was found that those who regularly have excessive drinking were four times more likely to access e-cigarettes than those who never drink. In all of those that drink, regardless of smoking status, e-cigarette access was associated with excessive drinking and involvement with violence after drinking. The researchers said their findings suggest that teenagers who use e-cigarettes are most susceptible(易受影响的)to other forms of substance use and risk-taking behaviour.
How have e-cigarettes been promoted in the market?

选项 A、As a device meeting the physical and mental needs of smokers.
B、As a product preventing smokers from using tobacco products.
C、As a much healthier substitute for traditional cigarettes.
D、As a new device promoted among youngsters.

答案C

解析 事实细节题。本题考查电子烟在市场上推广的信息。由定位句可知,电子烟已经被营销宣传为比传统香烟更健康的一种替代品。C)是对定位句的同义转述,故为答案。A)“作为满足吸烟者身体和精神需求的一种装置”和D)“作为一种在年轻人当中推广的新装置”,在原文均未提及,故排除;B)“作为防止吸烟者使用烟草制品的一种产品”是对本段首句的曲解,alternative意为“供替代的选择”,因此,B)与此不符,故排除。
