Once upon a time, there was a frog. He lived in a well(井) and he never went out. He thought the sky was just as big as the mouth of the well.
One day, a bird was thirsty. She flew to this well and wanted to drink some water. The frog saw her and asked where she was from and how she came here. The bird said she was from the forest, and it was very far from here. It took her a long time to fly to this well. The frog couldn’t believe that. “What’s the forest? Besides, the sky is so small, and how can you fly for a long time?” The bird answered, “No, the sky is very big. And the world is also very very big. You should come out to see this. ”
The frog tried his best and finally he came out of the well. He was very surprised (吃惊的) and found that the world was really very big and he himself was very small.
