阅读理解。 Brodie's unusual story began in 1984 when she lost her right front leg in a hunting accident. Just two years old at the time, Brodie recovered quickly and had no trouble getting around on three legs.'Most people meeting her for the first time didn't know that she had only three legs because she was so quick,' says Mrs. Willey, Brodie's owner. Bad luck struck Brodie again at the end of 1989 when she developed bone cancer in her right hind (后面的) leg. To stop the cancer from spreading to the rest of her body, the leg had to be amputated (截肢). Mrs. Willey and her family considered putting Brodie to sleep , as owners often do. But Mrs. Willey believed that Brodie was brave enough to succeed at walking on two legs.' I knew that if any dog could make this situation work, it was Brodie, and if any owner could, it was me.' Soon after Brodie was brought home from the pet hospital, Mrs. Willey began walking the dog by tying a towel under her body and holding it like a sling (吊带). Brodie's left front leg was already strong to keep the front of her body balanced. Mrs. Willey said it was only a matter of time until Brodie was strong enough in her left hind leg and we let go of the sling. It has now been a year since her operation, and Brodie gets around like any four-legged dog. Mrs. Willey says,' It just proves that you can't give up anyone or any dog.' 1.
