Do you ever wish you were as thin as a model（模特）or as strong as your favourite football player？Maybe you wish you were taller or just thinner a little.Those thoughts are a natural part of growing up.But learning what you can and can't change about your body is part of growing up too.It can be hard to do.But when people accept the way they look，they often feel happier.Some children worry that they're not growing and developing as fast as their friends.It's important to know that puberty（青春期）doesn't happen at the same time for every child.And there is no special medicine that can make it happen sooner!
   Eating healthy food and exercising more can make all children feel better.Why？Because they will help you feel energetic（精力充沛的）and keep your body working just the way it should be.Watching TV and playing computer games can be fun，but they don't do much for your body because you sit when you do them.But when you move your body by playing，dancing，taking part in sports，or even cleaning your room，you exercise your muscles（肌肉）.When you exercise the muscle，it gets stronger.And when you have strong muscles，you can do whatever you want to do!
