A policeman was sitting in his car on the side of Highway 25, hoping to catch  speeders．After a while，a car full of elderly women slowly rolled by. The policeman  realized that the slow—moving car was a danger to other drivers on the highway, so he decided to ask them to pulled up．After the car had stopped on the side of road, the policeman got out and came to the car to speak to the drive. He said, “The speed  limit(限制)on this highway is fifty-five miles per hour．Why are you driving so slowly?” “Well，officer，I’ve seen a lot of signs on this highway that say‘ twenty- five’ not‘fifty—five'，”the old woman politely replied．

“Ma'am．”the officer told the driver．“those aren’t speed mean that you are driving on Highway 25．”

 “Oh，silly me．I didn't know．I'm sorry，officer．I'll be more carefully in the future .”she replied．

Then the police officer looked in the backseat of the car．He noticed that the elderly passengers looked frightened and were shaking with fear. The officer asked the driver，“What，s wrong with them? They 1ook like they ’ve been frightened to death by something.”
