Friday 阅读理解 D

Nine out of ten U.S. high school students aren’t getting enough exercise, and their habits tend to continue even after their graduation. Kids who don’t get enough exercise often face serious health problems later in life, including obesity (肥胖) and heart disease.

Part of the reason kids are not getting enough exercise may be due to the fact that only 29 percent of U.S. high schools have daily gym classes. Other reasons may include the increased amount of homework as children reach middle school, and the fact that modern kids tend to spend too much time on their cell phones.

Whatever the reasons, our kids are becoming fatter and less healthy, and the resulting cost to society is great—the money used to treat obesity-related illness in the U.S. is said to be nearly $200 billion. So is there a way to deal with this problem?

Government departments and schools can offer more chances for students to take physical activity—not just with facilities (设施), but with programs to encourage students to use them, because students aren’t using those facilities enough. Something needs to be done to push them. But the real responsibility lies at home. Raising healthy kids is largely the responsibility of parents, but more and more, it seems that parents are too busy themselves simply trying to make ends meet to set a good example for their children and encourage them to have healthy, active lifestyles.

There are no easy methods, but everyone seems to agree that something must be done or else we will simply become a nation full of fat people.
