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.
Teeth are important. Strong , healthy teeth help you chew(咀嚼) foods that help you grow. They help you speak clearly. And yes , they help you look best. Here are some tips for you to take care of your teeth:
⒈ Brush your teeth the right way.
Brush your teeth at least twice a day – after breakfast and before bedtime. If you can, brush after lunch or after sweet snacks, too. Brush all of your teeth, not just the front ones. Spend time brushing teeth along the sides and back of your mouth. Spend at least three minutes each time you brush. Play a song you like to help pass the time. Get a new toothbrush every three months. When you buy toothbrush, be sure it has soft bristles(鬃毛).
⒉ Learn how to floss(用牙线清洁牙齿) your teeth.
Flossing is a very important way to keep your teeth healthy. Food may hide between two teeth. Flossing can help get rid of it. You'll need to floss your teeth at least once a day.
⒊ Have good eating habits.
You need to be careful about what you eat and drink. Eating sugar is a major cause of tooth decay(蛀牙).Eat lots of fruits and vegetables and drink water instead of soda(苏打).
How do animals communicate (交流) with each other? They have special “languages”. In fact, they are using signals (信号). Different signals have different meanings.
For example, when a bee (蜜蜂) finds food somewhere, it flies home quickly. It can't speak, but it can tell others by dancing. Other bees will know where and how far the food is.
Some animals show their feelings by making sounds. For example, when a dog is angry, it barks (吠). At this time, you'd better stay away from it. Birds can make several sounds to show different meanings. Sometimes we humans show feelings by making sounds instead of by speaking. For example, when we feel painful (疼痛的), we cry“Oh!”or“Ouch!”.
We humans have languages and words. We can communicate face to face by speaking. We can write down what happened in order to remember clearly. We can also send (寄) messages to people far away. But animals can't.

What is your favorite color? Do you like yellow, orange and red? You do, you must be a person full of hopeful(充满希望的) happy feelings about life. Do you like gray and blue? Then maybe you are quiet, and you would rather go after than go before. And sometimes you feel unhappy. If you love green, you are strong-minded. 43You wish to do everything well and want other people to see you are successful. At least this is what psychologists (心理学者) tell us. They tell us that we don't choose our favorite color as we grow up. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly.
A yellow room makes us feel happier and more comfortable（舒适）than a dark green one; and a red dress brings warmth and gladness to the saddest winter day. ⑸Light and bright colors make people not only happier but more active. It is a fact that factory workers work better, harder, and have few accidents when their machines are painted (漆) orange rather than black or dark gray. Remember, then, that if you feel low, you can brighten your day or your life with a new shirt or new colorful things. Remember also that you will know your friends better when you find out what colors they like or dislike. And don't forget that anyone can guess a lot about your character (性格) when you choose something in different colors.
