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 _ 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.

It said that there would be a race and the winner would win many prizes. The race started from the bear's house. From there, the runners had to cross the river.

Shiny got down from Smily's back and Smily climbed on Shiny's back again. Shiny ran fast. They reached the finish line first. "Both of them are the winners."
