______, the healthier you will be．

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.
