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.
According to Prof. Mark Bellis, ______.

选项 A、e-cigarettes contain something addictive which has a longstanding effect on kids
B、e-cigarettes may be harmful to the lungs and immune system
C、the use of e-cigarettes penetrates into youth culture as rapidly as other drug uses
D、e-cigarettes make teenagers who have never smoked before start smoking

答案A

解析 事实细节题。本题考查马克·贝里斯教授的观点。第三段末句提到,虽然关于电子烟的争论主要集中在其是否是一种通往使用烟草香烟的途径,但电子烟本身含有非常容易上瘾的药物,可能对孩子造成更严重、更持久的影响,因为他们的大脑还在发育。A)是对该段末句大意的概括,故为答案。B)“电子烟可能对肺部和免疫系统有害”是先前的研究结果,并不是马克·贝里斯教授的观点,故排除;C)“电子烟的使用渗透到青少年文化的速度和其他药物使用一样快”是对本段第三句的曲解。原文中without precedent意为“史无前例的”,并非“一样的”,故排除;D)“电子烟使得以前从不吸烟的青少年开始吸烟”是利物浦约翰摩尔斯大学的研究人员的发现,而非马克·贝里斯教授的观点,故排除。
