     I came to study in the US last fall. My life had been    1    since I arrived at Andover. Although I had several
outside-class activities, I hadn't taken any official leadership position.
     This    2    changed when I received an e-mail from Ms Griffith, my cluster (一组, 一群) dean (主任),    3    
that a new female DC Rep was needed. DC Rep    4    Discipline Committee Representative.    5    boarding
school (寄宿学校) students break serious rules, like using    6   , getting drunk or cheating in their studies. The
punishments given to such students are    7    by a DC Rep, a house adviser, two student representatives, the
cluster president and the cluster dean. I was interested in becoming a DC Rep for my cluster, Pine Knoll,    8    
so were other students. We had to hold an election and Ms Griffith asked us to write    9    to be sent to
everyone in Pine Knoll.
     I thought hard about what to write. I didn't want to make any   10  , because they are difficult to keep. So I
started my speech by explaining   11   I wanted to become a DC Rep. "I want to serve Pine Knoll and also learn
how American boarding schools carry out discipline," I wrote   12  .
     I made three   13   that said, "Vote For Teresa" and put them on every exit of my dorm (宿舍) so that people
would   14   my name when they went to vote.
     Although I tried hard, I didn't win the election. I was   15  , but my positive (乐观的) nature did not allow me
to   16   for very long. I actually   17   when my friends tried to   18   me, "Teresa, I am sorry."
     "Don't be sorry for me. I'm very happy to have taken part in the election," I said.
     It is true that the process is much more important than the   19  . I am surprised and happy to   20   my
hidden courage.
