聪明的猴子
Jennifer was a scientist. She made many tests with different animals. Monkey was the cleverest of all the animals.
One day Jennifer put a monkey in a room. She also put some small boxes in the room. There was some food in only one box. “How long will it take the monkey to find the food?” Jennifer said to herself. Then she left the room and waited outside. Three minutes later, she put her eye to the keyhole. What did she see? She saw the eye of the monkey. The monkey was on the other side of the door and looked at Jennifer through the keyhole.
