Directions: Read the passage carefully. Then answer the questions or complete the statements in the fewest

possible words.

     Phys ed (physical education) is making a comeback as a part of the school core curriculum (核心课程),

but with a difference. While group sports are still part of the curriculum, the new way is to teach skills that

are useful beyond gym class. Instead of learning how to climb a rope, children are taught to lift weights,

balance their diets and build physical endurance. In this way,kids are given the tools and skills and experiences

so they can lead a physically active life the rest of their life.

     Considering that 15 percent of American children 6 to 18 are overweight, supporters say more money and

thought must be put into phys ed curriculum. In many cases, that may mean not just replacing the old gym-

class model with fitness programs but also starting up phys ed programs because school boards often "put

P.E. on the chopping block, cutting it entirely or decreasing its teachers or the days it is offered," says Alicia

Moag-Stahlberg, the executive director of Action for Health Kids. The difference in phys ed programs is partly

due to the lack of a national standard."Physical education needs to be part of the core curriculum," she added.

     The wisdom of the new approach has some scientific support. Researchers at the University of Wisconsin

have demonstrated how effective the fit-for-life model of gym class can be. They observed how 50 overweight

children lost more weight when they cycled and skied cross-country than when they played sports. The

researchers also found that teaching sports like football resulted in less overall movement, partly because

reluctant students were able to sit on the bench.

     Another problem with simply teaching group sports in gym class is that only a tiny percentage of students

continue playing them after graduating from high school. The new method teaches sells that translate to

adulthood.

(Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)
