Mr. Jenkins is a farmer. One day he drove his truck to town and on the way his truck knocked down a boy and hurt him. He took the boy to a hospital and he paid a lot of money for that, but the boy’s parents wanted to get more money from him, so they said their son couldn’t lift（举起） his right arm above his head.

Mr. Jenkins’ lawyer came and asked the boy some questions. “Now, my boy,” he said, “Mr. Jenkins’ truck knocked you down in the street.”“Yes, sir,” he said. “And you can’t lift your right arm now?”“Yes, sir,” he said. “Could you show me how high you can lift your right arm?” Slowly the boy lifted his right arm before his nose. “Poor boy,” said the lawyer, “And how high could you lift before the accident?”“Oh, I could lift it very high.” Said the boy, and the right hand went up high above his head.
