By the third year of teaching I’d begun to expect Christmas break more for the school holiday and less for the excitement of the children. I was teaching fourth grade and my students had made me   36  . I just had to get through one of the hardest days of the school year.
  The morning bell rang. I walked   37  through the cold into the overly heated school building. Twenty-two smiling faces   38  me at the school bus stop. I forced myself to   39  their smiles. Back into the classroom, they   40 , comparing plans for the   41  . I had to remove one student from each arm   42  I could take a seat at my desk for my morning duties. Before I could find my roll book(点名册) my desk was covered with   43  and gifts followed by a   44  of “Merry Christmas” wishes.
 “Oh, thank you,” I must have   45  a million times. Each gift was truly special to me, except my   46  mood(情绪). It was kind of them to   47  me. After a while, I heard a small nervous   48  say my name. I looked up to see Brandon standing   49  by my desk, holding a small, round gift. “This is for you.”
  “Thank you, Sweetheart.” I laid it on my desk with the others.
 “Um, could you   50  it now?”
 I gently tore at the paper and tape. “  51  ,” he said, “it’s breakable.” Slowly I opened a small, green Christmas tree ornament(装饰物), complete with a hook already   52 . It dawned on me what he had done. Then a nearby student said that he just pulled that off his own tree. I tried to keep my   53  back.
 Later that day, I sat   54  the ornament in my hands. Was I really so important to this child that he had searched for something to give me? Now every year as I   55  pull a green Christmas ball from my ornament box, I remember the deep influence my students have on me.
