"You'll never be able to move your arm again."These are the words that were spoken to my grandpa over thirty years ago in 1984.It's a tragic (悲惨的) story，but the ending isn't so tragic.

　　It was a normal day at the DANA Corp.plant in Lima，Ohio.That day my grandpa was working on one of the factory's transformers (变压器)．He was told to replace the transformer in one of the machines.Normally，this is a two­man job; however，one workmate had a day off，and my grandpa had to remove the huge transformer on his own. As a result，an accident happened.The 682­pound transformer tipped (倾斜) and fell on his left shoulder，pinning (使不能动弹) him against the transformer and the machine.

　　My grandpa told me that he could see his left arm on the right side and he knew it was bad but he never panicked because if he had panicked he could have been injured far worse. He pushed the transformer back onto the platform and rushed to the hospital by himself.The doctors took a picture of it.The doctors said his shoulder was torn up. Muscles were torn around his rotator cuff (肩袖)，and the doctors operated on it immediately.After surgery the doctor told my grandpa，"You won't be able to move your arm again."

　　My grandpa said，"I can't work with one arm，"so he went to physical therapy (疗法)．He would go to therapy every day and try to move his arm.At home he would lie on the floor and pull on his fingers to move his arm.He spent all his time on his physical therapy. After two months' therapy his situation was improved，but the doctors said he wouldn't be able to lift ten pounds over his head，but after thirty­two years，my grandpa has never had a problem with his left shoulder since.Now he only has a four­inch scar on his shoulder.
