I recently heard a story about a famous scientist. Because of his great achievements, he was thought to be more creative than a common person. When he was asked why he was able(do) this, he gave the answer. It all came from an experience with his mother when he was about three years old. "I triedget a bottle of milk from the fridge but it fell, spilling(溢出）the milk all over the floor— a sea of milk! I was frightened and I didn't know what to do!" he said.

    His mother heard the noise and got into the kitchen. "I(consider) how to explain this to you, Mum, "he said. Instead of(punish) him, she said, "Robert, what a great mess you have made! I haven't seena sea of milk before! Well, since the milk has already been spilled, would you like(play) in the milk for a while? We will clean itafter that. "Then, he did so. After a few minutes, his mother said, "You know, Robert, whenever you (make) a mess like this, finally you have to do it by yourself. "He used a sponge（海绵）and together they cleaned up the spilled milk.

    His mother then said, " You know, we failed to successfully carry a big milk bottle with two tiny hands just. Let's go out in the yard and fill the bottle with water to see if you can discover a way to carry it. "Then the little boy learned that if he grasped(抓紧）the bottle at the top with both hands, he could carry it without(drop) it.

    What a wonderful lesson!
