单选题 As a traffic policeman, I have often heard all kinds of excuses told by drivers whose driving speed is too fast. On a cold winter evening, I was carrying out my work in a car when a completely new Blue Bird passed by me at an astonishing speed. I managed to catch up with it, and then got in the way. A young man got out of this car, saying that someone in his car was seriously ill and that he was taking the patient to the hospital. I let the man go, but decided to follow the driver to the hospital, for I had been cheated by some other drivers quite a few times. At the parking lot (停车场) in front of the hospital, I was really feeling foolish about not trusting the driver when the young man took great trouble to get an elderly lady off his car. I was about to give the young man a hand when I overheard the struggling woman say in an angry voice, "Leave me alone. You told the policeman someone was sick, so you should be the patient."
