I recently heard a story about a famous scientist. Because of his great achievements, he was thought to be more creative than the common person. When he _______(ask) why he was able to do this, he gave the answer. It all came from an experience with his mother when he was about three years old. “I______(try) to get a bottle of milk from the fridge when I lost the bottle and 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 all this to you, mom.” he said. Instead of_____(punish) him, she said, “Robert, what a great mess you have made! I__ (not see) such a huge sea of milk before! Well, since the milk has already been spilled, would you like____ (play) in the milk for a while? We ______(clean) it up after 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 clean it up.” He used a sponge （海绵）and together they cleaned up the spilled milk.
His mother then said, “You know, we _____(fail) in how to successfully carry a big milk bottle with two tiny hands just now. Let’s go out in the yard and fill the bottle with water to see if you _______(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 dropping it.
What a wonderful lesson!
