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 stay in bed, feeling very sad.
What makes us ill? It is germs(細菌). Germs are everywhere. They are very small and you can’t find them with your eyes, but you can see them with a microscope(顯微鏡). They are very very small and there could be hundreds of them on a very small thing.
Germs are always found in dirty water. When we look at dirty water under the microscope, we shall see them in it. So your father and mother will not let you drink dirty water.
Germs can be found not only in water but also in air and dust(灰塵). If you cut your finger, if some of the dust from the floor goes into the cut(割開處), some of the germs would go into your finger. Your finger would become big and red, and you will have much pain in it. Sometimes the germs would go into all of your body, and you would have pain everywhere.

When we have small cuts in the skin(皮膚), something strange may happen. The cuts are able to heal(痊愈) themselves in a couple of days. How does this happen? Read on, and you will find out the secret.
Every living thing on the earth is made up of cells(細胞). Cells grow and make new cells. Most cells are very small and we can't see them with our eyes. Different cells have different uses. Our skin cells are special ones. The cells on the outside of our skin are old dead cells. New skin cells are right under the outside. These are the living skin cells. They work for our bodies. They help protect our bodies and heal cuts.
Our bodies make skin cells all the time. As the old cells fall off, new cells grow in the same place. Each person makes about 18 kg of skin cells during his or her life. Outside skin cells fit together closely with no gaps between them. When you cut yourself, you can harm your skin cells. A small cut will not be harmful. Your skin will quickly heal itself by making new skin cells. How do skin cells work? First, the cells near the cut get bigger and move into the gap. Next, these bigger cells meet in the middle. They form a new layer(層) of skin cells. Finally, new cells will grow until the gap disappears. In this way, your skin can grow and get well itself. How amazing the small cells are! Next time you have a cut, don't worry about it. Maybe in a few days, you will be surprised to find it healed.

| A．突起 | B．條紋 | C．縫隙 | D．代溝 |
