閱讀短文,完成表格,每空一詞。

Every living thing on the earth is made up of cells (細(xì)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 surface (表面) 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 ( 復(fù)原,治愈) 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 18kg of skin cells during his or her life. Surface skin cells fit together closely with no gaps between them. When you cut or burn yourself, you can harm ( 傷 害 ) your skin cells. A small cut will not do much harm. Your skin will quickly heal itself by making new skin cells in just some days. 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 completely. In this way, your skin can grow and get well itself.

How amazing the tiny cells are! Next time you have a cut, don’t worry about it. Maybe in a few days, you will find it healed.
