Most of the class considered turkey and other traditional goodies of the season. These, the teacher thought, would be the 2 of most of her students' art. And they were. But in her class there was a different kind of boy, Douglas. He was always unhappy. When other children played together, he was likely to stand close by the teacher's side. The boy drew a hand in his picture. 3 else. Just an empty hand.
Whose hand 4 it be? His abstract (抽象的) picture made classmates really 5. One child guessed it was the hand of the6, because they raise turkeys. Another suggested police officers, because the police 7 and care for people. Still others guessed it was the hand of God, for God feeds us. And so the discussion went — 8 the teacher almost forgot the young artist himself.
When the children went on to other projects, she 9 at Douglas' desk, bent down, and asked him 10 hand it was. The little boy looked away and said in a low voice, "It's 11, teacher."

Or, "Let me 13 you how to hold your pencil." Or, "Let's do this together." Douglas was most thankful for his teacher's hand.
