     The teacher is giving his students a written examination. He wants them to write a composition (作文).

The title is My Dog, no less than 150 words. Little Tom thinks for a moment, 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

for a moment and continues, "Every day I take Bobby out for a walk. He likes having a walk, and I like

giving him...We both like it." He counts (数) the words: 67. Tom scratches (抓) his head, looks out of

the window, looks at the blackboard and continues, "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 (敲,打) him. He smiles happily and writes quickly, "When I want Bobby to

come, I call 'Bobby'. If he doesn't come, I call again, 'Bobby!' 'Bobby!' If he still doesn't come, I just call

'Bobby! Bobby! Bobby!'" Tom counts the words: 149. He adds one more"Bobby" and writes his name at

the bottom of the paper and hands it in to the teacher.
