Even though it was only October, my students were already whispering about Christmas plans. With each passing day everyone became more  36  , waiting for the final school bell. Upon its  37  everyone would run for their coats and go home, everyone except David.
David was a small boy in ragged (破旧的) clothes. I had often  38  what kind of home life David had, and what kind of mother could send her son to school dressed so  39  for the cold winter months, without a coat, boots, or gloves. But something made David  40 . I can still remember he was always  41  a smile and willing to help. He always  42  after school to straighten chairs and mop the floor. We never talked much. He  43  just simply smile and ask what else he could do, then thank me for letting him stay and slowly  44  home.
Weeks passed and the  45  over the coming Christmas grew into restlessness until the last day of  46  before the holiday break. I smiled in  47  as the last of them hurried out of the door. Turning around I saw David  48  standing by my desk.
“I have something for you,” he said and  49  from behind his back a small box.  50  it to me, he said anxiously, “Open it.” I took the box from him, thanked him and slowly unwrapped it. I lifted the lid and to my  51  I saw nothing. I looked at David‘s smiling face and back into the box and said, “The box is nice, David, but it’s  52 .”
“Oh no, it isn’t,” said David. “It’s full of love. My mum told me before she died that love was something you couldn’t see or touch unless you know it’s there.”
Tears filled my eyes  53  I looked at the proud dirty face that I had rarely given  54  to. After that Christmas, David and I became good friends and I never forgot the meaning  55  the little empty box set on my desk.
