Have a healthy lifestyle

As we all know, health is important.

Height is just one of the 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 them out.

But genes don't decide 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 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 6 cm a year between age 3 and the time when they start puberty.

Your doctor will know how your growth has been going over the years. 2 cm here and 3 cm 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 growth spurt(高峰) during puberty. The age for starting puberty is about 10 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 after your body starts to show the first changes of puberty.

Li Chuang is a 15-year-old boy, but he has been a smoker for three years. His teeth and fingers have turned a bit yellow.

"I first tried smoking after watching TV. It makes me feel excited and I think it looks cool," he said. Not all students smoke as much as Li but there are lots of child smokers. A report says 32% of boys and 13% of girls in middle schools in China have smoked. Some are as young as 11 when they first try!

Doctors say smoking can make people get illnesses, like lung (肺) cancer.

Not only that smoking costs a lot of money, too! Stop smoking, children! It's bad for your health.
