     More and more people like bicycling and it is no surprise. It is fun, healthy and good for the environment.

Maybe that's why there are 1.4 billion bicycles and only 400 million cars on roads worldwide today. Bikes can

take you almost anywhere, and there is no oil cost! 

     Get on a bicycle and ride around your neighbourhood. You may discover something new all around you.

Stopping and getting off a bike is easier than stopping and getting out of your car. You can bike to work and

benefit (受益) from the enjoyable exercise without polluting the environment. You don't even have to ride all the

way.

     Folding (折叠) bikes work well for people who ride the train. Just fold the bike and take it with you. You can

do the same on an airplane. A folding bike can be packed in a suitcase. You can also take a common bike with

you when you fly. But be sure to look for information by getting on airline websites. Not all airlines are

bicycle-friendly to travellers. 

     Health Benefits of Bicycling: 

    ● It helps to prevent heart diseases.

    ● Bicycling helps to control your weight. A 15-minute bike ride to and from work three times a week burns

off five kilos of fat in a year. 

    ● Bicycling can improve your mood (心情). Exercise like bicycling has been shown to make people feel

better, more relaxed and self-confident.

    ● Bicycling is healthier than driving.
