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 (潜力). Getting enough sleep and enough exercise will help you grow to the right height.
No doubt you're wondering how fast you should grow. There's no perfect or right answer. Kids grow about 2 inches (5 centimetres) a year between age 3 and 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 centimetres here and 2 inches there are not nearly 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.
Don't be scared 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 10 for girls and about 11 for boys. But it can be earlier or later – between 7 and 13 for girls, 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.

      The world has many beautiful sounds. We can hear the songs of birds and the laugh of people. We can listen to cool music and news reports. And it's all because of our ears! They bring us a world of sounds.
      But some people can't hear any sound at all. Some are born deaf. Others can hear well in their childhood, nut too many loud sounds hurt their ears later on.
       Many people in China can't hear ordinary sounds clearly. Lots of them are children. Most of them are born with good hearing. But six children of every 1,000 have hearing problems when they are born. And if a children has hearing problems, he or she usually will also have some learning problems at school.
        A lot of things can cause fearing problems, like, too much earwax is not good for our hearing. And noise louder than 85 decibels (分贝) can hurt our ears and make us lose our hearing for a short time or even for ever.
Hearing is important for all of us. So we should do our best to give our ears special care. Don't forget to do the following:
◎ Try to stay away from places with too much noise. If you have to go, wear earplugs.
◎ When swimming, remember to put earplugs into your ears to stop water from getting in.
◎ Never put anything sharp into your ears. If you think you have too much earwax, ask your parents to help you clean it out.
     Keep these things in mind. Then you won't be saying “WHAT? WHAT?” when you are older.
