When his mother came in, 41 shouting at him or giving him a lecture, she said, "Robert, what a great and wonderful 42 you have made! I have 43 seen such a huge pool of milk. Well, the damage has already been 44. Would you like to get down and 45 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 46 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 47 experiment in how to effectively carry a big milk bottle with two 48 hands. Let's go out in the back yard and fill the bottle with water and see if you can make it." The little boy learned that if he 49 the bottle at the top near the lip with both hands, he could carry it without dropping it. What a wonderful 50!
This scientist then remarked that it was at that moment that he knew he didn't need to be 51to make mistakes. Instead, he learned that mistakes were just 52 for learning something new, which is, 53, what scientific experiments are all about. Even if the experiment "doesn't54," we usually learn something 55 from it.
