One day, Tony Wang was crossing the road, when he was hit by a car. He fell and broke his arm. The policeman soon arrived and took Tony to a hospital. There a doctor operated on his arm. Then he put the arm in a cast（石膏）. Tony could not move it at all.“You must keep your arm in a cast for six weeks,”the doctor said.“That will give the broken arm a chance（机会）to get better.”At the end of six weeks, Tony went back to the hospital. The doctor used a large saw（锯）to cut the cast. Then he took arm out of the cast.“can you move your arm, Tony?”he asked. Tony tried to move his arm. At first it was difficult, but soon he could move it easily.“Yes, it's fine,”he said.“Thank you very much.”“In a few days it will be as good as new,”the doctor said,“Just exercise it a little.”“Will I be able to play the guitar（吉他）? Tony asked. The doctor smiled.“Of course you will.”he said.“You'll have no problems.”“That is good news.”Tony said.“Because I couldn't play it at all.”

The keys to reaching or staying at a healthy weight are regular exercise and good eating habits. Teens should get 60 minutes or more of physical activity a day. Note the word “activity”. As long as you’re getting your body moving, it doesn’t have to mean doing difficult exercise or going to the sports hall every day. All that matters is that each week you get the right balance of activity, including aerobics (有氧运动), strength building, and flexibility (柔韧) exercise. Make exercise a habit by arranging some time every day.
On days when you have soccer practice or an aerobics class, you may have no trouble exercising for an hour or more. But most of us are busy, and 60 minutes a day for exercise seems like a lot of time. The good news is that it’s OK to divide it into shorter exercise breaks throughout the day.
Just as you might have a healthy snack to stop yourself from getting hungry, exercise snacks can keep energy levels high. So get up 15 minutes early and do some stretching (伸展) activity. Walk fast or run slowly for 15 minutes after lunch. Do the same thing after school — or walk or bike home. Add to that taking the stairs, PE class, and walking between classes during the day, and you’ve probably reached your 60 minutes.
