     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.

    You are made of seventy-three percent water. You have 206 bones. There are more sweat glands (汗腺) in
your feet than in any other part of your body. There are about sixty muscles in your face; you use twenty of
them to smile but forty to frown (皱眉). Your heart beats over 100,000 times each day. You are really amazing!
    The human body is a complex machine. From the day we are born our bodies grow and change because of
our environment, diet and habits. The body has many different organ (器官) systems and parts that work
together to allow us to breathe, move, see, talk, and eat food all at the same time. Most of the time we are
unaware (预兆) of what is happening in our bodies; usually it's only when we get sick or feel pain that we
notice. 
    Many people do not take enough care of their complex machines. Bad habits like smoking, drinking too much
alcohol (酒精), and eating junk food damage our bodies. Stress can also cause health problems. People who
worry a lot or have busy jobs often don't get enough sleep, or don't eat properly. We also damage our bodies by
playing sports or having accidents. In 1999, Americans made more than 102,000,000 visits to emergency rooms.
The two most common reasons were for injure (伤害) and poisoning. ER patients were also treated for many
other medical problems-from bad cuts and broken bones to serious illness that needed surgery (外科手术).
    As with any machine, the better you take care of it, the longer it will last. Of course, the best way to take
care of your amazing machine is to eat the right food, do regular exercise, and get enough sleep. Oh, and don't
forget to smile!
