Walk to school every day? That will work, but not if you like sleep in. If you like bad smells and crowding(擁擠), the bus might be your best Choice. But why not a bicycle? A bicycle will get you there faster than your feet and will save your money.
This is why you see more bicycles than any other kind of transportation in China, about 500 million of them. That’s close to one for every two people in the whole country. But if you survey your class at school, you may will find a higher rate(比率).
Bicycles became popular because they are fun for people and at the same time help develop a strong body. No vehicle is better than a bicycle for enjoying an autumn weekend outside the city with parents or friends. You can travel on small, quiet paths. You also can park your bicycle beside the path wherever you want to stop to admire the beauty.
Cycling every day helps people build with city healthier hearts and stronger muscles(肌肉). Scientists say a 30-minute ride every day can help you lose weight.
Today, bicycles also are popular with city planners. They see bicycles as a good way to reduce heavy traffic. Unlike buses, bicycles produce no exhaust(尾氣) and don’t burn energy. Many countries are encouraging more daily use of bicycles.

The world itself is becoming much smaller by using modern traffic and modern communication means(交流方式). Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in a place, men moved to another place. But this is no longer true. Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad to all living things in the world, but it is not only one kind of pollution. Water pollution kills fish and pollutes drinking water. Noise pollution makes us become angry more easily.
Many countries are making rules to fight against pollution. They stop the people from burning coal in houses and factories in the city, and from blowing dirty smoke into the air.
The pollution of SO2 is now the most dangerous problem of air pollution. It is mostly caused by heavy traffic. It is certain that if there are fewer people driving, there will be less air pollution.

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 (姿勢(shì)) 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 (低頭垂肩地坐) on a ball," says Witt, "but it feels awful." Because the students are moving, their blood (血液) increases. That carries more oxygen (氧氣 to the brain (大腦), so the kids have more energy and can focus longer.
"Furthermore, they're fun." says Pownali.
