阅读理解。 The Americans and Russians, at the height of the arms race, realized that if they continued in the usual manner they were going to blow up the whole world. One day, they sat down and decided to settle the whole argument with one dog fight. They'd spent five years training the best fighting dog in the world and whichever side's dog won would have the right to control the world. The losing side would have to lay down its arms. The Russians found the biggest, meanest, Doberman and Rottweiler in the world and trained them with the biggest meanest Siberian wolves. They selected only the biggest and strongest young dogs from each litter (窝), killed his brothers or sisters, and gave him all the milk. They used steroids (类固醇) and trainers and after five years came up with the biggest meanest dog the world had ever seen. Its cage needed steel bars that were three inches and nobody could get near it. When the day came for the fight, the Americans showed up with a strange animal. It was a nine-foot long Dachshund. Everyone felt sorry for the Americans because they knew there was no way that this dog could possibly last ten seconds with the Russian dog. When the cages were opened up, the Dachshund came out and wrapped itself around the outside of the ring. It had the Russian dog almost surrounded. When the Russian dog leaned over to bite the Dachshund's neck, the Dachshund reached out and consumed the Russian dog in one bite. There was nothing left at the entire Russian dog. The Russians came up to the Americans, shaking their hands in doubt. 'We don't understand how this could have happened. We had our best people working for five years with the meanest Doberman and Rottweiler in the world and the biggest, meanest Siberian wolves.' 'That is nothing,' an American replied. 'We had our best plastic surgeons (外形整容医生) working for five years to make a crocodile look like a Dachshund.' 1.
