Mr. King works in a shop and drives a car for the manager.  He drives carefully and can keep calm in time of danger.  And he escaped from several accidents.  The manager pays him more and the traffic policemen often speak highly of him.   Mr. Baker， one of his friends， works in a factory outside the city.  It's far from his house and he has to go to work by bus.  As the traffic is crowded in the morning， sometimes he's late for the work.  His manager warns the young man that he will be  sent away unless he gets to his office on time.  He hopes to  buy a car， but he hasn't enough money.  He decides to buy an  oldd one.    He went to the flea （跳蚤） market and at last he chose a beautiful but cheap car.  He said he wanted to have a trial （试验） drive， the seller agreed.  He called Mr.  King  and asked him to help him.  Mr.  King examined the car at first and then drove it away.  It was five in the morning and there were few cars in the street.  At first he drove slowly and it worked well.  Then he drove fast.  And when he reached a crossing， the lights turned red.  He tried to stop it， but he failed and nearly hit an old woman who was crossing the street.  A policeman told him to stop， but the car went on until it hit a big tree by the road.  "Didn't you hear me？" the policeman asked angrily.   "Yes， I did， sir，" said Mr.  King， "Since it doesn't listen to me，can it obey you？"
