Height is just one of the thousands of features your genes（基因）decide．In fact，because you have two parents，your genes（66）provide you a height that usually lands somewhere between the height of each parent．If both your parents are tall，then most probably you will be tall，too，（67）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 （68）everything．For example，eating an unhealthy diet can keep you from growing to your full potential（潜力）．Getting plenty of sleep and enough exercise will help you grow to the （69）expectedheight．
No doubt（怀疑）you're wondering how fast you should grow．It （70）depends．There's no perfect or right answer．Generally speaking，kids grow about 2inches （6centimeters） a year （71）between age 3and the time when they start puberty （when your body starts changing and becoming more grown up）．
Your doctor will know how your growth has been going over the years．Two centimeters here and 2inches there are not nearly as （72）importantas the height you're at now，how you've been growing up to this point，and what other（73）changesyour body may be going through．
Don't be scared if you seem to have grown a lot in a very short time．Everyone has a growth spurt（高峰） （74）during puberty．The age for starting puberty（生长发育期） is about 10for girls and about 11for boys．But it can be earlier or later--between 7and 13for girls and 9and 15for boys．
You'll usually begin to notice that you're growing （75）faster about a year or so after your body starts to show the first changes of puberty（青春期）．
