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.
What do we learn about e-cigarettes?
选项 A、They contain the chemical matters identical with tobacco.
B、They have strong ties with drinking among teenagers.
C、They act as an approach to tobacco cigarette use.
D、They are available in the grocery stores.
答案B
解析 事实细节题。本题考查对电子烟的了解。第三段第二句提到，专家们还发现电子烟与青少年饮酒“密切相关”。B)项中的have strong ties with是原文中were“strongly related”to的同义转述，故答案为B)。A)“电子烟含有与烟草相同的化学物质”是对第二段第二句的曲解，原文说的是电子烟产生的有毒化学物质与在烟草中发现的类似，而不是相同，故排除；C)“电子烟充当一种使用烟草香烟的途径”是针对第三段末句中whether or not they act as a gateway to tobacco cigarette use设置的干扰项，原文并没有如此肯定地表达，故排除；D)“电子烟能够在杂货店买到”，原文并未提及，故排除。
