    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!

     Many earthquakes (地震) happen without warning, so it is important to know what to do wherever you
are during an earthquake. Here are some top tips on how to stay safe in an earthquake. 
    ◆ Keep a cool head. Worry may make bad decisions. Think about what you should do. The first several
seconds are important. 
    ◆ If you are indoors during an earthquake, hide under a heavy desk and protect your head. Stay away from
windows and anything that could fall on you.
    ◆ If you are in a crowded hall away from the door, don't rush to the exit. You will find too many people
trying to get out at the same time. Instead, hide under a desk or a table. Do not get into a lift during an
earthquake!
    ◆Stay in a safe area until you are sure it's OK to leave. Some aftershocks (余震) may follow an earthquake.
These are as dangerous as the earthquake. 
    ◆If you are at home and you smell gas, open a window and leave the building quickly.
    ◆ If you are outdoors, find a clear place away from buildings, trees, street lights and power lines.
    ◆If you are buried in debris (埋在废墟), you may make noises by knocking at the rocks. Shouting will use

important for you.
