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, Puert
o 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. What will happen if a student sits on a chair all day in school? The student will _________.
| A．pay more attention to his lessons | B．be fun |
| C．like to move around | D．sit up straighter |
How long has Dottie Pownall used the balls?
| A．About three years. | B．Only one year. |
| C．In 2008. | D．Since he was a fifth-grade teacher. |
In how many countries are the balls used as the students' chairs?
| A．Four. | B．Three. | C．Two. | D．One. |
Teachers choose balls instead of chairs because sitting on balls helps the kids___________.
| A．improve the students' posture and attention | B．slouch on the chairs |
| C．have fun | D．Both A and C are correct answers. |
Which is better for kids to study in class, sitting on a chair or sitting on a ball?
| A．Sitting on a chair. | B．Sitting on a ball. |

A predator(捕食性动物) kills and eats other animals as prey(猎物).Sometimes it also becomes food for other predators. Polar bears are the largest of all the land predators. They can run across snow and swim in icy water for hours without rest. Their favorite food is seal. Not all big animals live on small animals. Hippos have heavy bodies and huge mouths. But they don’t eat animals. They just eat grass.
Some predators use speed to catch their prey. Cheetahs are the fastest animals on land. They can run up to 70km an hour. Other predators use their senses to find their food. Sharks can see, smell, hear, feel and taste. They can also sense electrical currents(电流 )from other animals’ bodies. Some fish try to hide themselves, but with this sixth sense, sharks can always find them. Sharks have smooth bodies. This helps them swim without using lots of energy. They need to save their energy because they never really sleep and never stop hunting. Flying is a useful skill for many predators in the sky. The butcher bird is the most interesting predator. It has a special way of eating its prey. First it kills its prey. Then it hangs it on a fence or in a tree, just like a butcher hangs meat in his shop. Finally, it eats its prey.
Some people hunt and kill more animals than any other predator. They not only hunt for food. They also hunt for fun. They kill sharks for their fins, and tigers for skins. Those human hunters are the worst predators on Earth. The following statements are about “predators”, which one is true?

Dick often goes traveling when the summer holiday begins. But he was out of luck this summer.
He went to an old temple(庙)on a high mountain by himself. On his way there it suddenly began to rain heavily and he hurried to go down the mountain.

The next morning the rain stopped and he found the bridge was damaged. He saw the river was not too deep and tried to swim across it. In the middle of the river the water nearly washed him away. Luckily , two farmers saved him, but he lost his bag. They gave him some food and dry clothes. He thanked them and went to the nearest town to call up his parents.

“A room on the first floor is twenty dollars, on the second floor, fifteen dollars and on the third, ten dollars,” answered the owner.
