问题     Over the past 30 years, the childhood obesity rate in the United States has doubled for children and tripled for adolescents. Since 95 percent of young people are enrolled in schools, many experts believe innovative school programs can go a long way to helping fight childhood obesity.
    Calvary Preschool in Pittsford, Vermont, is even teaching the children how to enjoy playing outside. The idea of having to teach kids how to play outside leaves Anita Caldwell, a teacher there, dumbfounded. "You just kind of take for granted that kids want to go outside and play but then you recognize, when you talk to them, that they don’t," says Caldwell. "They spend their day with a large screen TV and some snacks."
    Fellow teacher, Laura Peterson, agrees. "When I was growing up—’shoo!’— out the door in the morning and you’d play outside until the streetlights came on at night." But it’s different today, she says. With many parents working, it’s often easier for them to have their kids play inside with a video game or watch TV
    Peterson says an early childhood education class got her thinking about ways to incorporate more activity into their school day. She began to research playground equipment and found many experts recommending the benefits of "back to nature" unstructured play. Kids today are more used to structured play, where they have to follow rules, listen to a coach, or play on specific equipment.
    So, she says, their first big challenge was getting the kids to freely explore the things along the trail.
    "When we started to go off the trail into the woods, the kids had no idea what to do. I said, ’Wow, look at all these trees, let’s play!’ And they kind of looked at me, ’What are you talking about?’ So we had to show them how to walk on trees and how to swing off them onto other branches and see the little holes underneath that you can play in."
    At a time when many schools have cut back on their physical education programs, Calvary’s weekly hike day is unique. One day a week outside probably isn’t enough, Peterson says. But as she watches her students run through the woods, she smiles, and says it’s a good start.
What is the opinion of many experts on childhood obesity?
选项 A、Schools are largely to blame for the problem.
B、Schools can actually do little about the problem.
C、Schools can play a big role in addressing the problem.
D、Schools are supposed to offer solutions to the problem.
答案C
解析 第一段介绍了美国儿童和青少年肥胖率不断攀升的问题。许多专家认为由于95％的青少年都在学校读书，因此学校的一些创新课程安排也许对解决儿童肥胖问题大有帮助。第一段并没有提到肥胖问题是谁造成的，也没有说学校应该为此负责，提供解决方案。因此正确答案是C。
