     Have you ever been ill? When you are ill, you must be unhappy because your body becomes hot, and there

are pains all over your body. You don't want to work and you have to stay in bed, and you will feel very sad.

     What make us ill? They are germs. Germs are everywhere. They are very small and you can't find them

with your eyes. But you can see them with a microscope (显微镜), we will see a lot of them in it. So your

father and mother will not let you drink dirty water.

     Germs are not only found in water. They are found in air and dust. If you get a cut in the finger, and if

some of the dust from the floor goes into the cut, germs will come into your finger. Your finger will become

big and red, and you will have much pain in it. Sometimes if the germs go into all of your body, you may have

pain in every part of the body.
