    What do you think is the most common illness? Do you get ill sometimes? We are lucky to live now, because there are lots of medicines to make people better.
    The most common illness in the world is the cold. It often begins with a sore throat. Then you sneeze and your nose runs. You usually have a headache too. Often you cough later. It’s not a very bad illness, but you can feel quite ill.
    There isn’t a cure (治愈) for a cold, but you can take medicines to make you feel better. For instance, aspirin (阿斯匹林) can stop your headache. It is good to rest, and to drink a lot of water too. A doctor once said to me, “With the proper medicine, a cold will continue for seven days. With no medicine, it will continue for a whole week!”
    Where does our medicine come from? A long time ago, people knew that some plants made them feel better. They ate the leaves, the roots, the fruit, or the seeds of plants. For instance, the juice of lemons makes a sore throat feel better.
    In modern times, scientists have looked at these plants, and found out which chemicals (化学物质) are in them. Many of our medicines today are made from those chemicals.
    There are some illnesses which we can’t cure yet. And nobody has found a cure for old age. But because of modern medicines, most people now live longer than their grandparents.

    In the sea there are many islands. In its warm waters there are some little ones. We call them coral(珊瑚) islands.
    A coral island is very nice to look at. It looks like a ring of land with trees, grass, and flowers on it. One part of the ring is open to the water. There is a little round lake inside the island.
    If you look into this lake, you will see beautiful coral. You may think they are flowers.
    If you look at a piece of coral, you will see many little holes in it. In each of these holes a very small sea animal has lived. These sea animals make the coral.
    They began to build under the water. Year after year, the coral grew higher and higher. At last it grew out of the water.
    Then the sea brought to it small trees and something else. After some years, these things changed into earth. Sometimes the wind brought seeds to this earth. Sometimes birds flew over it and brought seeds to the island. The little seeds grew. In a few years there were plants all over the island. In a few more years there were trees growing there.
    So you see, these islands were built little by little. The workers were very small. Don’t they teach us a lesson? Can you think what the lesson is?
