Have you ever been ill? When you are ill，you feel unhappy because your body be comes hot，and there are pains all over your body．You don’t want to work, you stay in bed and feel very sad．

    What makes us ill? It is germs（細(xì)菌）．Germs are everywhere．They are too small and you can’t find them with your eyes，but you can see them with a microscope（顯微鏡）．They are very small and there could be hundreds of them on a very small thing．
