A man was driving at 70 miles in a 40-mile-zone, when a police car came behind him with the flashers(警灯) on. As he pulled over and stopped, he could see a policeman getting out of his car. Right away the man started thinking of excuses to give, as this was not the first time, he had been in similar situations many times before.

As the policeman came to him, he said, “Hi, officer, I guess you caught me a little bit over the limit. I was in a rush to get home, to be with my wife and kids, you know my younger son wasn’t feeling too well, when I left home this morning.”

The policeman said, “Well, I guess so,” and started scribbling(速写) in his notebook. As minutes went by, he could see from the side view mirror, the policeman was still scribbling. The man was wondering why he hadn’t asked for his driver’s license so far.  A few moments later, the policeman came to his window and handed him a folded paper, and returned back to his car without saying a single word. The man started to wonder, how much this ticket is going to be as he began to unfold the paper. He was surprised it was not a ticket as he began to read:

“I had a daughter who was killed by a speeding car at the age of six, by a speeding driver like you. He got a fine (惩罚), a few months in prison, and was free, free to hug his two other daughters. I only had one, and now I have to wait until I get to heaven before I can hug her again. I have tried to forgive that man a thousand times, and I thought I had. Maybe I really did forgive him, but I have to do it again, even right now. So pray(为……祈祷) for me, and be careful when you drive again, my son is all I have left.”

The man was completely dumbfounded(目瞪口呆的) and could not move for the next few minutes. When finally he did, he drove slowly, even a few miles under the speed limit, praying for forgiveness.

A. Because the man drove after drinking.

B. Because the man drove at a speed of 40 miles an hour.

C. Because the man drove over the speed limit

B. he recognized the man who had driven the speeding car who killed his daughter

C. the man who had killed the policeman’s daughter was free to do anything in prison

D. the man who had killed the policeman’s daughter hugged his own daughters in prison

55. Why did the man at last drive slowly?

B. Because he heard his son was feeling well.

C. Because he was driving in a 40-mile-zone.
