A frog (青蛙) is born in a small river. When he is young, the river is his home. He doesn't know his
parents, but he has hundreds of brothers and sisters. He swims about and plays with them all the time. At
that time, he doesn't look like his parents. He has no legs and he has a big tail (尾巴). So he looks like a fish.

now. Then he's going to eat a lot of bad insects (害虫).
