Sitting on a chair all day in school can make anyone want to move around. So, more and more teachers are letting students have a ball. By sitting on exercise balls instead of chairs, teachers find students' posture (姿势) and attention improve.

Dottie Pownall, a fifth-grade teacher in West Virginia, USA, has been using balls as chairs since December 2008. "The students love them", she says. Pownall took a survey of her students. She found that 80% of the students thought sitting on the balls helped them pay more attention to what they were learning.

The teacher, Pisa Witt, felt so strongly about the use of balls as chairs, she started Witt Fitt. This company encourages the use of the balls. And the company educates not only teachers but also students on how to use them. "Our products are used in 24 states, three provinces in Canada, Puerto Rico ('波多黎各) and Japan," says Witt. "Research shows that sitting on the balls makes them sit up straighter. You can slouch (低头垂肩地坐) on a ball," says Witt, "but it feels awful." Because the students are moving, their blood (血液) increases. That carries more oxygen (氧气 to the brain (大脑), so the kids have more energy and can focus longer.

"Furthermore, they're fun." says Pownali.

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.

A. 童年时期 B.婴幼儿时期 C.习惯养成期 D. 生长发育期

2. If you want to know how fast and how tall you should grow, _____.

A. you should have enough exercise B. you can ask doctors for help

A. how the genes work in your body B. when is the time you grow fast

C. why you look like your parents D. how you grow to a certain height

4. After reading this passage, we can explain 　　　　　　　　　.

A. how good it is to be a doctor B. how much sleep time we need

C. why genes can’t decide everything D. what healthy diet is

5. Which is NOT mentioned in the passage?

A. Your height most probably depends on how high your parents are.

B. Girls’ age for starting puberty is usually earlier than that for boys’.

C. The time showing the first changes of puberty is never noticed.

D. You may be scared sometimes when you grow too fast.

Mr. Brown was on his way home from the railway station. It was very late, and he was alone on the dark road. Suddenly he heard someone behind him. He began to walk faster. The man behind him walked faster, too. He walked more slowly, and the man moved more slowly, too. He began to run, and the man was following him and he was really scared.

There was a wall on one side of the road, and he quickly climbed up on it and jumped down on the other side. “If he passes and doesn’t stop,” Mr. Brown thought, “everything will be all right.” But the man didn’t pass. He climbed up on the wall and jumped down, too. Mr. Brown’s only thought was, “I’m in great danger!” He stood up and shouted, “What do you want? Why are you following me?”

Dear editors (编辑),

I’m a slow (慢的) student in my class. Most of my classmates are much better than me. So I get very stressed out. It’s difficult to keep on working hard and it’s really not fun. And I think although I spend much time studying for the tests, I can’t get good grades. My father gives me some help sometimes. He tells me not to worry about it. But what do you think I should do?
