Physical Education Aims for Active Lives, Fewer Painful Memories (1/2)
[划词 ]
参考答案: Common sense would tell us that physically active children may be more likely to become active and healthy adults.
In the United States, elementary and middle schools are advised to give students two and a half hours of physical activity a week. That is what the Centers for Disease Control and Prevention and the American Heart Association recommend. They say high schools should provide about four hours of physical activity each week.
Yet many schools across the country have reduced their physical education programs. Criticism of the cuts has led in some places to efforts to give students more time for exercise, not less. The future health of Americans may depend on it.
Just this week, a study reported that life expectancy has fallen or is no longer increasing in some parts of the United States. The situation is worst among poor people in the southern states, and especially women. Public health researchers say it is largely the result of increases in obesity, smoking and high blood pressure. They also blame differences in health services around the country.
