Question

    In a national survey, just 1 in 3 students thought that smoking on some days, but not others, can cause a lot of harm. This smoking pattern is common. It is also dangerous. In fact, its health risks are about the same as smoking heavily, report Stephen Amrock and Michael Weitzman. Their new study’s findings show that most kids do not see risks in smoking the occasional (偶尔的) cigarette.

For their study, Amrock and Weitzman analyzed data from the 2012 National Youth Tobacco Survey. It had probed (探究) tobacco-related knowledge, attitudes and behaviors in 24,658 students. All were in grades 6 through 12 and lived throughout the 50 U. S. states and the district of Columbia.

Most teens knew that heavy smoking can be harmful. About 2 in every 3 students recognized that smoking even just a few cigarettes each day can be harmful (有危害的). Only 1 in3 students, however, recognized that occasional—non-daily—smoking is harmful. Among teens who smoke this way—intermittently—just 1 out of every 7 understood their habit was dangerous.

Occasional smoking is not safe, so “we really need to have a conversation” with whoever thinks otherwise, notes Dave Dobbins. He heads research and public education at Legacy, a group based in Washington, D. C. It encourages teens to reject tobacco. “Intermittent smoking carries lots of risks,” Dobbins explains. These include the chance that light use will progress to heavier smoking. “We explain to kids that light smoking is smoking,” says Dobbins, who was not connected with the study. And, he adds, his group points out that “the dangers begin right away”.

Adults who are light or intermittent smokers are those most willing and able to quit. Amrock and Weitzman note. Most smokers start by age 18. That’s why the NYU School of Medicine researchers suggest anti-smoking efforts should target youth who today are light or occasional smokers.

【解析】

这是一篇说明文。短文通过研究证明，轻度或偶尔吸烟对青少年的健康是有危害的，研究者呼吁多关注轻度或偶尔吸烟者。

1.主旨大意题。根据第一段In a national survey, just 1 in 3 students thought that smoking on some days, but not others, can cause a lot of harm. This smoking pattern is common. It is also dangerous. In fact, its health risks are about the same as smoking heavily可知，一项全国性的调查中，只有三分之一的学生认为偶尔吸烟会造成很大的危害。这种吸烟方式很常见但是也很危险。事实上，偶尔吸烟所带来的健康风险与大量吸烟所带来的健康风险差不多。接下来文章对此展开了讲述，所以文章主要讲的是偶尔吸烟。故选A项。

2.细节理解题。根据第三段About 2 in every 3 students recognized that smoking even just a few cigarettes each day can be harmful (有危害的). Only 1 in 3 students, however, recognized that occasional—non-daily—smoking is harmful.可知，大约三分之二的学生认识到每天只吸几支烟是有害的。然而，只有三分之一的学生认识到偶尔——非每日——吸烟有害健康。所以在第三段可以找到显示学生对不同吸烟模式看法的数据。故选B项。

3.词义猜测题。根据第三段 Only 1 in3 students, however, recognized that occasional—non-daily—smoking is harmful.可知，只有三分之一的学生认识到偶尔——非每日——吸烟有害健康。划线单词是对this way的解释，this way代指的是上一句的 occasional--non-daily--smoking。由此可知划线单词的意思是“偶尔地”。所以在偶尔吸烟的青少年中，只有1 / 7的人明白他们的习惯是危险的。所以通过上下文可以判断出，划线词的意思是“偶尔地”。故选C项。

4.推理判断题。根据第四段We explain to kids that light smoking is smoking,” says Dobbins, who was not connected with the study. And, he adds, his group points out that “the dangers begin right away”.可知，我们向孩子们解释，轻度吸烟就是吸烟”多宾斯说，他没有参与这项研究。他补充道，他的团队指出“轻度吸烟的危害很快会显现”。由此判断出戴夫·多宾斯同意儿童轻度吸烟的危害很快就会显现。故选A项。
