One day, the animal school was quietly taking exams.
Suddenly, the seven-star ladybug called out: "Teacher, the little dragonfly peeked at my test paper."
The teacher said: "Don't blame the little dragonfly, you see, he is not paying attention. Do you want to answer the question?"
"No, it peeked at me too!" said the little snail.
"Actually," said the little dragonfly, "I can see your papers, but I will never peek."
"What?" Everyone was even more surprised. .
This time the teacher solved the mystery. He said: "Some of our animals have many eyes, called compound eyes. Just like a small dragonfly, it has more than 18,000 small eyes in total! Although I can't move, I can see the things around me."
"So thats it." Everyone concentrated on answering the questions again.
