第6题

Mrs. Grey lived in the country, but she worked in London. She drove to the railway station in her car every morning, and left it in the station car park until she arrived back on the train in the evening. She was a careful driver, but one morning she was rather late, so she was going faster than usual when she had an accident in a narrow road not far from her home.

What happened was that another car was coming in the opposite direction, and either that one or Mrs. Grey's car was too far in the middle of the road, or perhaps both of them were. They ran into each other and were both damaged, although not enough to stop them from driving.

Both Mrs. Grey and the other driver, who was a young man whom she had seen in the district but had not met, got out of their cars, and Mrs. Grey said, "I'm afraid I haven't got time to waste on an accident this morning, as I have a very important appointment in town at nine, and I suppose you're a busy man too." .

"Yes, I am," the young man said, "but we'll have to c. all the police for insurance purposes, won't we? They won't pay for the damage unless we have reported the accident to the police and they have come and seen what happened."

"Yes, certainly," Mrs. Grey answered, "but I have something to suggest. We won't be committing a crime if we go away now in our cars, and then come back to the scene of the accident, say, at six this evening, and put them in exactly the same positions as they are in now. Then we can call the police. They won't know what time the accident happened, and the insurance companies won't care either as long as we can send them a police report of the accident. " " What a good idea !" the young man said happily. "So I'll be waiting here at six o'clock this evening. I won't be late!" "Nor will I," Mrs. Grey answered. She and the young man exchanged visiting cards, and then each drove off to their work.

When Mrs. Grey arrived at the station from London at a quarter to six that evening, she got into her car, drove to the place where the accident had happened, and found the young man waiting there in his car. They put both cars in exactly the same positions as they had been in after the accident, and then Mrs. Grey called the police, using the telephone in her car, as if the accident had just happened.

The most suitable title for this passage is______.

A．A Late Car Accident

B．A Funny Car Accident

C．A Bad Car Accident

D．A Lucky Car Accident
