问题     Teenagers at risk of depression, anxiety and suicide often wear their troubles like a neon(霓虹灯)sign. Their risky behaviors—drinking too much alcohol, using illegal drugs, smoking cigarettes and skipping school—can alert parents and teachers that serious problems are brewing.
But a new study finds that there’s another group of adolescents who are in nearly as much danger of experiencing the same psychiatric symptoms: teens who use tons of media, don’t get enough sleep and have a sedentary(不爱活动的)lifestyle.
    Of course, that may sound like a description of every teenager on the planet. But the study warns that it is teenagers who engage in all three of these practices in the extreme who are truly in jeopardy. Because their behaviors are not usually seen as a red flag, these young people have been dubbed the "invisible risk" group by the study’s authors.
    "In some ways they’re at greater risk of falling through the cracks," says researcher Vladimir Carli. " While most parents, teachers and clinicians would react to an adolescent using drugs or getting drunk, they may easily overlook teenagers who are engaging in inconspicuous behaviors. "
    The study’s authors surveyed 12,395 students and analyzed nine risk behaviors, including excessive alcohol use, illegal drug use, heavy smoking, high media use and truancy(逃学). Their aim was to determine the relationship between these risk behaviors and mental health issues in teenagers.
    About 58% of the students demonstrated none or few of the risk behaviors. Some 13% scored high on all nine of the risk behaviors. And 29%, the " invisible risk" group, scored high on three in particular: They spent five hours a day or more on electronic devices. They slept six hours a night or less. And they neglected " other healthy activities. "
    The group that scored high on all nine of the risk behaviors was most likely to show symptoms of depression: in all, nearly 15% of this group reported being depressed, compared with just 4% of the low-risk group. But the invisible group wasn’t far behind the high-risk set, with more than 13% of them exhibiting depression.
    The findings caught Carli off guard. "We were very surprised," he says. "The high-risk group and low-risk group are obvious. But this third group was not only unexpected, it was so distinct and so large—nearly one third of our sample—that it became a key finding of the study. "
    Carli says that one of the most significant things about his study is that it provides new early-warning signs for parents, teachers and mental health-care providers. And early identification, support and treatment for mental health issues, he says, are the best ways to keep them from turning into fullblown disorders. [br] What does the author mean by saying "Teenagers at risk of depression, anxiety and suicide often wear their troubles like a neon sign"(Lines 1 -2, Para. 1)?
选项 A、Mental problems can now be found in large numbers of teenagers.
B、Teenagers’ mental problems are getting more and more attention.
C、Teenagers’ mental problems are often too conspicuous not to be observed.
D、Depression and anxiety are the most common symptoms of mental problems.
答案 C
解析 语义理解题。定位句说到，有精神健康问题的青少年常常将其问题表现得如同霓虹灯标识一样，而随后说到了具体的表现形式有酗酒、使用违禁药品、逃学等，并指出这些行为会引起家长和教师的警惕，可见文中说到这些青少年将问题表现得如霓虹灯标识一样是为了说明这些表现形式很明显，难以被忽视，故答案为C)。
