people can live and grow food. They are learning a lot about the deserts. But more and more of the earth is
becoming desert all the time. Scientists may not be able to change the desert in time.
Why is more and more land becoming desert? Scientists think that people make deserts. People are doing
bad things to the earth.
Some places on the earth don"t get very much rain. But they still don"t become deserts. This is because
some green plants are growing there. Small green plants and grass are very important to dry places. Plants
don"t let the hot sun make the earth even drier. Plants don"t let the wind blow the dirt (泥土) away. When a
little bit of rain falls, the plants hold the water. Without plants, the land can become a desert much more
easily. (from www.zkenglish.com )

way.

about 41,846 cases (病例) in 30 provinces and regions. The number is increasing. Eighteen Chinese children
have died of the disease so far this year.
What causes the disease and why is it dangerous?
Hand-foot-mouth disease is a common childhood illness. It mainly affects children under the age of 10. It
gets its name from the rash (疹子) that develops on the hands and feet. It can also cause blisters (水泡) in your
mouth.
A child who has the disease will usually have a fever, a runny nose and sore throat. He or she doesn"t want
to eat or drink because of pain in the mouth.
Hand-foot-mouth disease is mostly not serious. The fever and rash clear within a few days. But in some
cases, the virus (病毒) affects the heart, lungs or brain. This puts the child"s life in danger.
A virus causes hand-foot-mouth disease. The disease spreads easily where a lot of young children are
together, such as in a child-care center. Sometimes it can also affect teenagers and adults.

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!
