       One afternoon, I went to pick up my mother from work.I got there a little early, so I   1   my car by a
small park, and   2   for her.
       As I looked outside the car window, I saw a little boy, around two years old, running   3   on the grass as his mother   4   from a short distance. The boy had a big smile on his face as if he had just been   5    free from some sort of prison .  The boy would then fall to the grass ,     6   up ,   without looking back at his
mother , run as   7   as he could ,again , still with a smile on his face ,as if nothing had happened .
       At that moment, I thought to myself , "why aren't most adults this way ?" Most adults, when they fall
down, make a big deal out of it and don't even   8   a second attempt. They would be so   9   that they
would not try again if someone saw them fall .Or , because they fall , they would find a good   10   for
themselves that they're not fit for it . They would end up too afraid to attempt again for fear of failure.
       However, with kids, when they fall down, they don't consider their falling down as a failure, instead,
they treat it as a   11   experience. They try again and again until they   12   .The answer must be that they
have not connected"falling down" with the word "failure". As a   13  , they are not discouraged in any way .
Besides, they   14   think to themselves that it's quite okay to fall down and that it's not wrong to do so. In
other words ,they allow themselves to make   15   , so they remain energetic.
I was deeply impressed by the boy's persistence (坚持不懈) and the manner in which he did.
