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    1   he thought he was able to be so much more    2   than the average person.

He responded that it all came from a(n)   3   with his mother that happened when he was about two. He had been trying to    4   milk from the fridge when he    5   the slippery (光滑的) bottle, its contents running all over the kitchen floor.

When his mother came in,   6   shouting at him or giving him a lecture, she said, ＂Robert, what a great and wonderful    7   you have made! I have    8   seen such a huge pool of milk. Well, the damage has already been    9   . Would you like to get down and    10   in the milk for a few minutes before we clean it up?＂

His mother said, ＂You know, what we have here is a    11   experiment in how to carry a big milk bottle with two    12   hands. Let’s fill the bottle with water and see if you can    13   it.＂ The little boy learned that if he    14   the bottle at the top near the lip with both hands, he could carry it without dropping it. What a wonderful    15   !

This scientist then said that it was at that moment that he knew he didn’t need to be    16   to make mistakes. Instead, he learned that mistakes were just    17   for learning something new, which is,   18   , what scientific experiments are all about. Even if the experiment ＂doesn’t    19   ＂, we usually learn something    20   from it.
