Question

翻译，英译中

Height is just one of the thousands of features 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 most probably 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 the expected height．But getting enough sleep and exercise will meet your need．
It s certain that you're wondering how fast you should grow．It depends．There's no perfect or right answer．Generally speaking，kids grow about 2 inches（6 cm）a year between age 3 and the time when they start adolescence．
Don't be scared if you seem to have grown a lot in a very short time．Everyone has a time to grow fastest during adolescence．The age for starting adolescence is about lo for girls and about 11 for boys．But it can be earlier or later--between 7 and 13 for girls and 9 and 15 for boys．
You'll usually begin to notice that you're growing faster about a year or so after your body starts to show the first changes of adolescence．

身高仅仅是基因决定的千万特征中的一个。事实上，因为你有父母，你的基因赋予了你的身高，这个身高通常达到你父母双亲的身高之间。如果你的父母都很高，你很可能也很高。但是如果你一直疑问你将长多高，问问你的医生看看他或者她是否能够帮你研究个明白。
但是基因也并不决定所有事。举个例子，不健康的饮食习惯让你不能达到预期的身高。但是足够的睡眠和锻炼可以满足你的要求。
你肯定想知道你应该长多快。这得看情况，没有一个完美正确的答案。通常来讲，孩子在3岁和青春期开始之间每年大约可以长2英寸（6厘米）。
如果你在很短的时间内长得很多，不要害怕。每个人在青春期期间都有一段时间长得很快。青春期的开始年龄对于女孩大约是10岁，对于男孩大约是11岁。但是也可能提前或推迟——女孩在7到13岁，男孩在9到15岁。
你通常会注意到，在你身体第一次显现出青春期的改变之后，你在这一年内长得很快。
