问题     Public service announcements donated by radio, print, television and Internet media will attempt to convince kids and their parents that leading a healthy lifestyle is important. We can’t get enough of this message about healthy lifestyle, because the news on obesity(the condition of being too fat), and especially childhood obesity, is grim. And it’s getting worse.
    The last few months have seen a lot of reports on obesity, all sending a clear message: obesity is overwhelming us. It’s damaging us physically, leading to increases in diabetes, arthritis, heart disease and other chronic conditions. And it’s breaking us financially, as our health care system crushes under the weight of the cost of treatments for these diseases.
    The journal Health Affairs published a study indicating that the cost of hospitalizing obese(too fat)children between 1999 and 2005 nearly doubled, with twice as many children requiring such care. The finding prompted the report’s lead researcher to say, " Obesity is the single biggest reason for the increase in health care costs. " In August, yet another study in the journal Academic Pediatrics showed the rate of severe obesity among U. S. children and teenagers aged 2 to 19 has more than tripled over the past three decades and risen more than 70 percent since 1994. Even here in Massachusetts, with universal health care, nearly one-third of our middle and high school students are overweight or obese.
    What’s frightening in these reports is what’s happening to our young people. Childhood obesity is particularly more harmful because the health effects of obesity at a young age can last a lifetime. If nothing changes, we’ll continue to see spending rise to higher and higher levels, and we may see an entire generation burdened with the long-term effects of a condition that might have been prevented.
    Adults recognize the issue. The University of Michigan C. S. Mott Children’s Hospital National Poll on Children’s Health again in 2009 ranked obesity as the top child health concern of adults, surpassing all other threats, including drug abuse, smoking, bullying, and Internet safety. The survey also found blacks and Hispanics rank obesity as the number one health issue for the first time.
    Promotions are all well and good; they call attention to the problem and keep it before the public. But the best solutions to the problem of childhood obesity likely rest with the notions of individual responsibility and parental supervision. Young people and their parents—because parental supervision and their roles in setting examples are critical to reversing the trend—must "take stock" of their exercise and eating habits.
In the first paragraph, public service announcements are mentioned to______.
选项 A、stress the importance of keeping a healthy lifestyle
B、explain why various media are booming today
C、highlight how our health care system works
D、introduce the topic of what has caused obesity
答案A
解析 例证题。根据题干提示定位至第一段。该段首先提到了由广播、新闻、电视和网络等多家媒体赞助的公益广告(public service announcements)。多家媒体参与其中是为了增加宣传力度，是为了让孩子和父母相信：健康的生活方式尤为重要。因此，第一段提及公益广告是为了强调保持健康生活方式的重要性，故[A]为正确答案。通过读第一段可知：在肥胖问题，尤其是儿童肥胖问题日益严重的今天，我们对健康的生活方式却知之甚少，因为我们无法获取更多的信息。显而易见，多家媒体赞助公益广告是为了向人们宣传远离肥胖、保持健康
