　　I recently heard a story about a famous scientist．Because of his great achievements，he was thought to be more creative than the ordinary person．When he （42）___（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 two years old．"I tried 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 （43）___ （consider）how to explain all this to you，mom．"He said．Instead of （44）___ （punish） him，she said，"Robert，what a great mess（杂乱） you have made!I （45）___ （not see） such a huge sea of milk before!Well，since the milk has already been spilled，would you like to play in the milk for a while？We （46）___ （clean） 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，you （47）___（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 can find a way to carry it．"Then the little boy learned that if he grasped （抓紧） the bottle at the top near the lip with both hands，he could carry it without dropping it．What a wonderful lesson!
