It was the night before the composition was due. As I looked at the list of topics (题目) , "The Art of Eating Spaghetti (意大利面条)" caught my eye. The word" spaghetti" brought back the  36   of an evening at Uncle Allen's in Belleville   37   all of us were seated around the table and Aunt Pat   38 spaghetti for supper. Spaghetti was an exotic (外来的) treat in   39    days. Never had I eaten spaghetti, and  40   of the grown-ups had enough experience to be   41   it. What laughing  42  we had about the  43  respectable method for moving spaghetti from plate to mouth.   44    , I wanted to write about that, but I wanted to   45   it down simply for my own   46   , not for Mr. Fleagle, my composition teacher.  47   , I would write something else.

When I finished it the night was half gone and there was no   48   left to write a proper com position for Mr. Fleagle. There was no choice next morning but to   49    my work. Two days pas­sed before Mr. Fleagle returned the  50    papers. He said, "Now, class, I want to read you a composition, 'The Art of Eating Spaghetti’. "

My words! He was reading my words out   51  to the whole class.  52  laughed, then the whole class was laughing with open-hearted enjoyment. I did my best not to show   53   , but what I was feeling was pure happiness,   54  my words had the power to make people  __55  .
