Each of us fails from time to time. If we are wise, we accept these failures as a   36 part of
the learning process. But all too often as parents and teachers we disallow this 37 right to our
children.
When I see a child 38 to this kind of pressure, I think of Donnie.
Donnie was my youngest third grader. His   39 of failure kept him from classroom games
that other children enjoyed. He   40 answered questions—he might be wrong.
I tried my best to build his    41   .But nothing changed until midterm , when Mary Anne , a student teacher , was assigned（安排） to our classroom .
She was young and pretty , and she loved children . My pupils , Donnie included , all   42    her.
One morning , we were working on math problems at the chalkboard . Donnie had    43   the problems with pains-taking tidiness . Pleased with his progress , I     44 the children with Mary Anne and went for art materials . When I returned , Donnie was in    45   . He’d missed the third problem .
My student teacher looked at me in despair . Suddenly her face   46    . From the desk we shared , she got a container filled with pencils .
“Look , Donnie,” she said, kneeling beside him and gently   47    the tear-stained face from his arms . “I’ve got something to    48   you.” She removed the pencils , one at a time , and placed them on his desk .
“See these   49    , Donnie,” she continued . “They belong to Mrs . Lindstrom and me . See how the erasers are    50   ? That’s because we make mistakes too . But we erase the mistakes and try again . That’s what you    51   learn to do , too.”
She kissed him and stood up . “Here”, she said , I’ll leave one of these pencils on 52     desk so you’ll remember that everybody makes mistakes,   53   teachers.” Donnie looked up with love in his eyes and a smile .
The pencil became Donnie’s   54 possession . That, together with Mary Anne’s frequent encouragement, gradually    55   him that it’s all right to make mistakes—as long as you erase them and try again .
