A farmer had some puppies（小狗）to 36 . He painted a sign advertising the puppies and 37__ nailing （钉）it to a post on the edge of his yard. As he was driving the last nail into the post, a little boy came to him. “Mister,” he said, “I want to buy one of your puppies.” “Well,” said the farmer, as he 38 the sweat off his face, “these puppies come from fine parents and cost 39 money. Do you have enough money?” The boy 40 his head for a moment. Then reaching into his pocket, he pulled out a handful of 41 and held it up to the farmer. “I’ve got thirty-nine cents. Is that enough to take a look?” “Sure,” said the farmer. And with that he 42  a whistle ( 口哨声), “Here, Dolly!” he called. 43 from the doghouse and down the ramp ran Dolly 44 by four little balls of fur. The little boy’ eyes danced with delight. As the dogs made their 45 to the fence, the little boy noticed something else stirring inside the doghouse. 46 another little ball appeared; this one noticeably smaller.  Then in a somewhat 47 manner the little pup began hobbling（蹒跚） toward the others, doing its best to 48 . “I want that one,” the little boy said, 49 to the smallest one. The farmer said, “Son, you don’t want that puppy. He will never be able to run and play with you 50 these other dogs would.” With that the little boy 51 back from the fence, and began 52 up one leg of his trousers. In doing so he exposed a steel support running down both sides of his leg 53 itself to a specially made 54 . Looking back up at the farmer, he said, “You see sir, I don't 55 too well myself, and he will need someone who understands.” 小题1: A．sell B．buy C．raise D．drive 小题2: A．set off B．set out C．set about D．set up 小题3: A．wiped B．removed C．settled D．drove 小题4: A．a number of B．quite a few C．a great deal of D．only a little 小题5: A．raised B．buried C．dropped D．shook 小题6: A．change B．price C．treasure D．wallet 小题7: A．made out B．put away C．gave away D．let out 小题8: A．In B．Away C．Out D．Up 小题9: A．equipped B．protected C．attacked D．followed 小题10: A．way B．direction C．path D．struggle 小题11: A．Rapidly B．Slowly C．Suddenly D．Simply 小题12: A．curious B．foolish C．ordinary D．active 小题13: A．catch up B．keep up C．put up D．make up 小题14: A．staring B．pointing C．greeting D．devoting 小题15: A．while B．as C．that D．what 小题16: A．stepped B．escaped C．went D．kept 小题17: A．pushing B．forcing C．rolling D．tearing 小题18: A．attaching B．attached C．being attached D．to attach 小题19: A．leg B．stick C．shoe D．foot 小题20: A．walk B．run C．live D．go
