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.

A lift is wonderful. It is really only a small room. Rooms usually stay in one place. Lifts travel up and down all day long.
Sometimes a worker stands in the lift. He or she
operates(操作)it up and down. In modern lifts there is
no worker. The people walk in. They know which floor they want. They push a
button(按纽)and 
the
lift goes to the floor. It is very fast and easy.
Lifts are very important for us. Why? Think about a
tall building. May
be
it has twenty floors. Maybe it has fifty or more. Who can walk up all the
stairs? Perhaps people can climb them one time. Can someone climb
thirty floors to an office everyday? Can small children walk up to their rooms
on the twenty–forth floor？Can
their mother and their father carry food up all those stairs? Of course not.
We can have high buildings because we have lifts. We could not have all the beautiful tall buildings in the world without lifts. They are really wonderful.
