　　I recently heard a story about a famous scientist．Because of his great achievement , he was thought to be more creative than the average person．When he was ask w　　1　　 he was able to do this ,he gave the answer．It all came from an e　　2　　 with his mother when he was about two years old．"I was trying to get a bottle of milk from the fridge when I lost the bottle and it fell, spilling the milk all over the floor a sea of milk ! I was f　　3　　 and I didn't know what to do ! " he said．

　　His mother heard the noise and got into the kitchen．" I was c　　4　　 how to explain all this to you ,mom．" he said．Instead of punishing(惩罚)him, she said "Robert ,what a great mess you have made! I have never seen such a huge sea of milk before!　well, since the milk has a　　5　　 been spilled ,would you like to play in the milk for a while ? We can it up after that．"

　　Indeed , 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 failed 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 can f　　6　　 a new way to carry it．"Then the little boy learned that if he grasped the bottle at the top near the lip with both hands , he could carry it w　　7　　 dropping it．

　　What a wonderful lesson!
