There once was a frog. He lived in a well (井). He ▲ got out of the well, so he thought the sky was as big as the mouth of the well.
One day, a crow came to the well. He saw the frog and said, “Frog, let’s have a talk.” Then the frog asked, “What do you do?” “I fly in the sky,” the crow said. The frog felt surprised (吃惊的) and said, “The sky is only as big as the mouth of the well. How do you fly in the sky?” The crow said, “The sky is very big. You always stay in the well, so you don’t know the world is big.” The frog said, “I don’t believe.” But the crow said, “You can come out and have a look by yourself (你自己).”
So the frog came out of the well. He was very surprised at how big the world was!
