The teacher is giving her students a written examination.
She wants them to write a composition.
The title is “My Dog.” No less than 150 word.
Little Tom thinks for a moment, and then he begins to write: “I have a dog. I call him Bobby. I like my dog. He is all black, only the nose is white...”
Tom stops writing, counts the words: 21. He scratches his head, thinking for a few moments and continues: “Every day I take Bobby out for a bath. He likes having a bath , and I like giving him ...We both like it.”
He counts the words again: 67.
Tom scratches his head again, looks out of the window, looks at the blackboard, but finds nothing there.
He has to continue: “Bobby likes sugar, so I often give him some sugar. But sometimes we do not have any sugar in the house, and then I do not give him any...”
He stops for a long time.
Suddenly a thought strikes Tom.
He smiles happily and writes quickly: “When I want Bobby to come, I call ‘Bobby’. If he does not come, I call again, ‘Bobby! Bobby! Bobby!’...”
Tom counts the words : 149. He adds one more “Bobby” , …writes down his name at the bottom of the paper and hands it in to the teacher.
