Passage Five
One evening Mr. Green was driving home along a lonely country road. He had ￡1,000 in his pocket. At the loneliest part of the road, a man asked for a lift(搭车). Mr. Green told him to get into the car and continued his driving. When he talked to the man and learned that the man had been in prison for robbery and had broken out of prison two days before, Mr. Green was very worried.
Suddenly he saw a police-car and had a bright idea. He just reached a small town where the speed limit was 30 miles an hour. But he drove the car as fast as it could go. He looked back and saw that the police-car had begun to chase him. After a mile or so the police-car overtook(赶上)him and ordered him to stop. A policeman got out and came to Mr. Green’ s car. Mr. Green hoped that he could tell the policeman about the escaped robber, but he felt the man had put a gun against his back. The policeman took out his notebook and pencil, saying he wanted Mr. Green’ s name and ad dress. Mr. Green asked to be taken to the police station, but the policeman said," No, you will have to appear at the police station later." Mr. Green had to do as the policeman told him. The policeman wrote his name and address down, put his notebook and pencil back in his pocket and gave Mr. Green a talk about dangerous driving. Then Mr. Green started up his car again and drove on.
Just as he reached the suburb of London, the passenger said, "I want to get off here. "Mr. Green stopped the car, the man got out and said, "Thanks for the lift. You’ ye been good to me. This is the least I can do in return. "And he handed Mr. Green the policeman’s notebook, which he stole while the policeman was talking to Mr. Green.

After reading the story, you can probably tell which of the following is NOT true.（）

A:Mr. Green didn' t go to the police station until the man got off his car and ran away. B:Mr. Green would go to the police station as soon as possible. C:The robber got out of Mr. Green' s car at the outskirts of London safely. D:Mr. Green might not go to the police station unless he was wante

When you think about math, you probably don’t think about breaking the law, solving mysteries or finding criminals. But a mathematician in Maryland does, and he has come up with mathematical tools to help police find criminals.
People who solve crimes look for patterns that might reveal the identity of the criminal. It’s long been believed, for example, that criminals will break the law closer to where they live. simply because it’s easier to get around in one’s own neighborhood. If police see a pattern of robberies in a certain area, they may look for a suspect who lives near the crime scenes. So, the farther away from the area a crime takes place, the less likely it is that the same criminal did it.
But Mike O’Leary, a mathematician at Towson University in Maryland, says that this kind of approach may be too simple. He says that police may get better clues to the location of an offender’s home base by combining these patterns with a city’s layout and historical crime records.
The records of past crimes contain geographical information and can reveal easy targets--that is, the kind of stores that might be less difficult to rob. Because these stores are along roads, the locations of past crimes contain information about where major streets and intersections(十字路口) are. O’Leary is writing a new computer program that will quickly provide this kind of information for a given city. His program also includes information about the people who live in the city, and information about how a criminal’s patterns change with age. (It’s been shown, for example, that the younger the criminal, the closer to home the crime. )
Other computer programmers have worked on similar software, but O’Leary’s uses more math. The mathematician plans to make his computer program available, free of charge, to police departments around the country.
The program is just one way to use math to fight crime. O’Leary says that criminology--the study of crime and criminals contains a lot of good math problems. "I feel like I’m in a gold mine and I’m the only one. who knows what gold looks like." he says. "It’s a lot of fun. /
O’Leary includes all the following information in writing his program EXCEPT

A:the records of past crimes. B:the locations of police bureaus. C:the people living in the city. D:the change of a criminal’s patterns with ag

In many ways, though, definition of such skills is quite unnecessary for an analysis of policing. It is really most unlikely that the average police officer will ever in his career perform or even witness those detective skills that he has enjoyed in countless TV products. The reason for this is simply that the vast majority of crimes are usually either very likely to be solved by routine investigation or they are very unlikely to be solved at all. Fortunately, the clear - up rate for serious crimes tends to be very high. Zander( 1979 )has shown why. In his study of Old bailey cases ,the identity of the defendant(被告) seems to have been reasonably clear in 87% of cases. Morgan (1980 and ongoing)has shown that well over 92% of crimes known to the police are discovered by the public who provide the majority of decisive information. In Morgan’s study, crimes that were" solved" contained in their crime files over twice the amount of qualitative information as crimes that were not" solved". The various bits of information in value in terms of probability of detection, "solving" of the crime. In this, where information was provided by the public during a police interview, the information was believed to the police" since it was felt that in an interview genuine police skills are involved in the collection of information. "Evidently this method can be justified thus, but will necessarily overestimate the police role. Nevertheless, in this analysis of crime files it was shown that in cases where crimes were solves, the public still provided nearly twice the amount of information as the police.
It can be learned from this passage that

A:excellent detective skills are highly necessary for the police to solve crimes. B:police officer’s experience in detection forms the basis for detective series on TV. C:actual solving of a crime case is more demanding than the TV series show us. D:the average police in practice rarely demonstrate or need the sophisticated detective skill shown on TV.
