专题04 阅读理解之说明文
(2022秋·广西南宁·九年级校联考期中)①Height 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.
②But genes don’t decide everything. For example, eating an unhealthy diet can stop you from growing to your full potential(潜力). Getting plenty of sleep and enough exercise will help you grow to the expected height.
③No doubt(怀疑) you’re wondering how fast you should grow. It depends. There’s no perfect or right answer. Generally speaking, kids grow about 6 centimeters a year between age 3 and the time when they start puberty (青春期) (when your body starts changing and becoming more grown up).
④Your doctor can know your growth these years. Two centimeters here and 2 inches there are not as important as the height you’re at now, how you’ve been growing up to this point, and what other changes your body may be going through.
⑤Don’t be scared if you seem to have grown a lot in a very short time. Everyone has a growth spurt (高峰) during puberty. The age for starting puberty is about 10 years old for girls and about 11 years old 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 puberty.
