听力题 Some people do not like anything to be out of place; they are never late for work; they return their books to the library on time; they remember people’s birthdays; and they pay their bills as soon as they arrive. Mr. Dodd is such a person. Mr. Dodd works in a bank and lives on his own. The only family he has is in the next town: his sister lives there with her husband, and their son, Mark. Mr. Dodd seldom visits his sister, but he sends them Christmas cards, and he has not forgotten one of Mark’s seventeen birthdays. Last week Mr. Dodd had quite a surprise. He drove home from the bank at the usual time, driving neither too slowly nor too fast; he parked his car where he always parked it, out of the way of other cars, and he went inside to make his evening meal. Right away, there was a knock at the door. Mr. Dodd opened the door and, to his surprise he found a policeman standing on the doorstep. “What have I done wrong?” Mr. Dodd asked himself, “Have I driven on the wrong side of the road? Has there been some trouble at the bank? Have I forgotten to pay an important bill?” “Hello, Uncle!” said the policeman. “My name’s Mark.”
