完形填空

      A famous scientist was asked why he was able to be so much more creative than the average person. What set him so far1from others?

  He 2that it all resulted from a (n) 3that occurred when he was three. He was tryingto4a bottle of milk from the refrigerator when he lost hold of the bottle, spilling its 5all over the kitchen floor.

      Instead of 6at him,his mother said,“Robert, what awonderful 7you have made!Ihave 8seen such a huge puddle of milk.Since the9is done,would you like to get down and play in the milk for a while 10cleaning it up?”

        Indeed, he did.“Robert,11you make a mess like this,12you have to clean it up and restore everything to its13order.”And then together they cleaned up the spilled milk.His mother then said,“Robert,that is a 14experiment in how to 15carry a big milk bottle.Let's go out in the yard and fill the bottle with water and see if youcan 16a way to carry a bottle of water without dropping it.”

       The scientist remarked he learned from that moment that mistakes were just 17for learning something new, which is18scientific experiments are all about.Even if the experiment “doesn't work”,we usually learn something19from it.

Wouldn't it be great if all 20would respond like Robert's mother?
