There was a farmer who fell and broke his hip while he was plowing（耕地） ,
and his horse immediately galloped（疾驰，飞奔） five miles to the nearest town and returned,
carrying a doctor on his back.
"That’s a pretty smart horse," the farmer’s friend later observed.
"Well, he’s not really so smart,"
the farmer said. "The doctor he brought back was a veterinarian!"
