I recently heard a story about a famous scientist who had made several very important medical breakthroughs(突破). He was being interviewed by a reporter who asked him he thought he was able to be so much more than the average person.

He responded that it all came from a(n) with his mother that occurred when he was about 2. He had been trying to milk from the fridge when he the slippery(光滑的) bottle, its contents running all over the kitchen floor.

When his mother came in, shouting at him or giving him a lecture, she said, “Robert, what a great and wonderful you have made! I have seen such a huge pool of milk. Well, the damage has already been . Would you like to get down and in the milk for a few minutes before we clean it up?”

Indeed, he did. After a few minutes, his mother said, “Robert, whenever you make a mess like this, eventually you have to restore everything to its proper order. So, how would you like to do that? We could use a sponge(海绵), a towel or a mop. Which do you prefer?” He chose the sponge.

His mother then said, “ You know, what we have here is a experiment in how to effectively carry a big milk bottle with two hands. Let’s go out in the back yard and fill the bottle with water and see if you can .” The little boy learned that if he the bottle at the top near the lip with both hands, he could carry it without dropping it. What a wonderful !

This scientist then said that it was at that moment that he knew he didn’t need to be to make mistakes. Instead, he learned that mistakes were just for learning something new, which is, , what scientific experiments are all about. Even if the experiment “doesn't ,” we usually learn something from it.
