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' attention improve.

　　Peter, a fifth-grade teacher in West Virginia, the USA, has been using balls as chairs since December 2010. "The students love them", he says. Peter took a survey of his students. He found that 80% of the students thought sitting on the balls helped them pay more attention to what they were learning.

　　The manager(经理), Mary, felt so strongly about the use of balls as chairs, she encourages the use of the balls. She hopes not only teachers but also students know how to use them. "Our products(产品) are used in 24 states(州), three provinces(省) in Canada, Puerto Rico and Japan," says Mary. "Research(调查) shows that sitting on the balls makes them sit up straighter," says Mary, "but it feels not boring." Because the students are moving, so the kids have more energy and can keep longer.

　　"Besides, they're fun." says Peter.

　　In Britain, people usually begin their talks with weather. For example, they will say"It's a fine day, isn't it?""Do you think it will rain?"

　　Many people believe that they are able to tell what the weather will be like. But they never agree with each other. One man may say, "How cloudy (阴的) it is now! It's going to rain." Another man will say, "No, it's going to be fine later."

　　People always hope the weather they want. For example, when a farmer needs water, he looks for something to tell him it's going to rain. When a man wants to travel, he is sure the weather will be fine quickly.

　　Now almost everyone listens to the weather report. It doesn't always tell us the weather we want, it only tells us what the weather will be like. But sometimes it makes mistakes(错误).

　　Early to bed and early to rise makes a man healthy, wealthy and wise.

　　This is an old English saying (谚语). It means that we should go to bed early at night and get up early in the morning. If we do, we shall be healthy. We shall also be rich and clever.

　　Is this true? Perhaps it is. The body must have enough sleep. Children of your age need ten hours' sleep every night. If you go to bed late, you can't have enough sleep. Then you can't think carefully and your homework will be wrong. You will not be wise and you may not become wealthy!

　　Some people go to bed late at night and get up late in the morning. This is not good for them. We should sleep at night when it is dark. The dark helps us sleep well. When the daylight comes, we should get up. This is the time for exercise. If the body is not used, it will become weak. Exercise keeps it strong.

　　Exercise helps the blood (血液) to move around inside the body. Blood takes nutrition (营养) to all parts of our bodies. The brains (大脑) in our heads also need blood. We think with our brains. If we keep our bodies healthy, and take exercise, we can think better!

　　Our bodies also need air to breathe (呼吸). Without air we will die. Get up early in the morning and we can have plenty of clean, fresh air. That will keep us healthy and happy.
