Height is just one of the thousands of features your genes 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 your full potential(潜力). Getting plenty of sleep and enough exercise will help you grow to the expected height.
No doubt 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 centimeters) 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 centimeters 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 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 or so after your body starts to show the first changes of puberty.

“ABC”and “Banana Persons”
You may know the English letters A, B and C. But do you know there are people called “ABC”? You may like eating bananas. But do you know there are people called “banana persons”? If you don’t know, I will tell you. They are Chinese people like you and me, but they aren’t in China.Why do people call them like that?
“ABC” means American-born Chinese. An “ABC” is a Chinese,
but was born in the United States. Sometimes, people also call them
“banana persons”. A banana is yellow outside and white inside. So when
a person is a banana, he or she is white (American) inside and yellow (Chinese)
outside.
They are born in America and they live in America for a long time. Even
their nationality(国籍) is American. So they think like Americans and do things
like Americans. But they still have Chinese blood(血). Their parents, grandparents
or even great-grandparents were from China.They all have black eyes and black hair.
So they look like us Chinese people. For example, we all know the famous scientist
C.N.Yang. He is an “ABC” and he is a “banana person”. We like him, although(虽然)
his nationality isn’t Chinese.
【小题1】What does “ABC” mean?

Imagine one day the water taps (水龙头) in your house stop running. You have to pay a lot of money to buy water from shops. And still there isn’t enough water for everyone. Your mother has to save the family’s shower water to use for washing clothes. Would you be able to stand that kind of life?
Probably not. But that is what kids in Yemen (也门) are experiencing (经历). According to a report, the capital, Sana, will run out of drinking water as early as 2025.
Because of the water shortage (短缺), the Yemen government often cuts the water supply (供应). Hannan, an 18-year-girl, tells the Teens, “In a good week we’ll have a water supply all week. But then the next week there will be water only for a day or two.”
Hannan says only rich people have enough water to use. They can buy water from the shops or from the water trucks. Private (私人的) companies own the trucks, They travel around the city every day to sell water--- at very high prices.
“ A lot of people can’t pay for it,” she says.
The government is thinking of making use of seawater. But it will cost a lot and it may not happen soon enough to help the people of Yemen.
