问题 Germs (细菌)
Have you ever been ill? When there is illness, there can be no happiness. When you are ill, you are unhappy, for your body becomes hot, and there are pains all over your body. You don’t want to work. You stay in bed, and are very sad.
What makes us ill?
Germs are everywhere. They are very small. You can’t see them with your eyes but you can see them with a microscope (显微镜). They are like the seeds of plants, but they are much smaller. They are very, very small and there could be hundreds of them on a very small thing.
Germs aren’t found only in water. They are found in air and dust (灰尘), too. If you cut your finger, and if some of the dust from the floor goes into the cut, some of the germs will go into your finger. Your finger will become big and red, and you will have much pain in it. Sometimes the germs can go all over your body, and you will have pain everywhere.
