A man was driving in the country when his motor（马达）stopped.He got out of the car to try to find the trouble."It's the distributor（配电盘）."said a voice near him.
Surprised to hear the voice，the man looked around.He saw an old horse."Did you say something？"he asked.The horse was still noding.
The man rushed to the nearest house.Excitedly he told what had happened."Was it an old horse with one flop（击拍）ear？"Asked the armer."Yes，that's the one."
"Well，don't pay any attention to him."the farmer laughed，"Perhaps something is wrong with his car.He doesn't know anything about cars.”
