Overweight (³¬ÖØ) is one of the biggest health problems now. Being overweight affects more than how you look. Too much fat can kill you. What's worse, overweight children turn into overweight adults

Get outside to exercise

Jim, a player on the school football team, had a weight problem not long time ago. He could never get anyone to play with him. So his father and he started playing football for a few minutes every night. Ten minutes turned into an hour or more. In just a few years, the heavy kid became healthy.

More TV means fat

Nearly every American kid watches TV for 2 hours and 56 minutes every day¡ªthat adds up to 44 days a year of sitting. More TV (or more Internet surfing, or more computer games) means more fat.

Eat an apple a day, walk around the house, play with your family... Do it today, and do it more tomorrow. It will help you a lot. ÊÔ×Å×öÒ»×ö

I am Wilson. My sister and I spent our summer holidays with our uncle this year. He was a geologist and loved to collect stones.

One day, he bought us two backpacks and asked us to go to the mountain with him. We walked the whole day. Every now and then he put stones in our backpacks. To our surprise, he also took some stones out from them. But we thought he had just found better stones.
