     It was the night before the composition was due. As I looked at the list of topics, "The Art of Eating
Spaghetti (意大利面条)" caught my eye. The word "spaghetti" brought back the    1    of an evening at
Uncle Alien's in Belleville    2    all of us were seated around the table and Aunt Pat    3    spaghetti for
supper. Spaghetti was an exotic (外来的) treat in    4    days. Never had I eaten spaghetti, and    5    of
the grown-ups had enough experience to be    6    it. What laughing    7    we had about the    8   
respectable method for moving spaghetti from plate to mouth.    9   , I wanted to write about that, but
I wanted to   10   it down simply for my own   11   not for Mr. Fleagle, my composition teacher.   12  ,
I would write something else.
     When I finished it the night was half gone and there was no   13   left to write a proper composition
for Mr. Fleagle. There was no choice next morning but to   14   my work. Two days passed before Mr.
Fleagle returned the   15   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   16   to the whole class.   17   laughed, then the whole
class was laughing with open-hearted enjoyment. I did my best not to show   18  , but what I was feeling
was pure happiness,   19   my words had the power to make people   20  .
