A farmer had some puppies (小狗) he needed to sell.  He painted a sign advertising the pups and
set about nailing it to a post on the edge of his yard.  As he was driving the last nail into the post,he felt a
tug(用力拉) on his clothes.
He looked down into the eyes of a little boy.
        "Mister," he said,"I want to buy one of your puppies." "Well,"said the farmer."these puppies come
from fine parents and cost a good deal of money. "
     The boy dropped his head for a moment. Then reaching deep into his pocket,he pulled out a handful
of change and held it up to the farmer. "I've got 39 cents. Is that enough to take a look?"
        "Sure,"  said the farmer.  And with that he let out a whistle (口哨) ," Here,Dolly! "  he called.
        Out from the doghouse and down the ramp (斜坡)ran Dolly followed by four little balls of fur.  The
little boy pressed his face against the chain link fence (铁丝网).  His eyes danced with delight.
       As the dogs made their way to the fence,the little boy noticed something else moving inside the doghouse. Slowly another little ball appeared; this one clearly smaller.Down the ramp it slid (滑倒).  Then in a
somewhat awkward manner the little pup began hobbling(跛行)  toward the others,doing its best to catch up…
      "I want that one," the little boy said,pointing to the little puppy.
      The farmer said: "Son,you don't want that puppy.  He will never be able to run and play with you like
these other dogs would. "
      The little boy stepped back from the fence,reached down,and began rolling up one leg of his trousers.  He showed a steel brace (钢支架) running down both sides of his leg attaching (绑) itself to a specially made shoe.  Looking back up at the farmer,he said: "You see sir,I don't run too well myself,and he will
need someone who understands. "The world is full of people who need someone who understands.
