10.Height is just one of the thousands of features (特征) that your genes (基因) decide.In fact,because you have two parents,your genes provide you a height that usually lands somewhere between the height of each parent.If both your parents are tall,then maybe you will be tall,too.But if you have questions about how tall you're going to be,ask your doctor if he or she can help you find it out.
But genes don't decide everything.For example,eating an unhealthy diet can keep you from growing to your full potential (潛力).Getting plenty of sleep and enough exercise will help you grow to the expected height.
It's natural that you're wondering how fast you should grow.There's no perfect or right answer.Generally speaking,kids grow about 6centimeters a year between age 3and the time when they startpuberty.
Your doctor will know how your growth has been going over the years.2cm here and 3cm there make a little difference to the height you're at now.How have you been growing up to this height?What other changes may your body be going through?
Don't be amazed if you seem to have grown a lot in a very short time.Everyone has a very quick growth during puberty.The age for starting puberty is about 10for girls and about 11for boys.But it can be earlier or later-between 7and 13for girls,9and 15for boys.
You'll usually begin to notice that you're growing faster about a year after your body starts to show the first changes of puberty.
