all over your body. You don't want to work , you stay in bed, feeling very sad.

     What makes us ill? It is germs(细菌). Germs are everywhere. They are very small and you can't find them with your

eyes, but you can see them with a microscope. They are very very small and there could be hundreds of them on a very
