David was a small boy in ragged clothes. I had often wondered what kind of home life David had, and what kind of mother could send her son to school     (dress) so inappropriately for the cold winter months. But something made David special. He always stayed after school     （straighten） chairs and mop the floor. He would just simply smile and ask what else he could do, then thank me for  (let ) him stay and slowly head for home.
On the last day of school before Christmas holiday break, I saw David    (quiet) standing by my desk.“I have something for you.” he said and (pull )from behind his back a small box. Handing it to me, he said anxiously, “  it.” I took the box from him, thanked him and slowly unwrapped it. I lifted the lid and to my surprise saw    . I looked at David’s smiling face and said, “The box is nice, David,     it’s empty.”“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 as I looked at the proud dirty face that I       (rarely give) attention to. After that Christmas, David and I became good friends and I never forgot     meaning behind the little empty box set on my desk.
