问题                        Calculating Crime
    When you think about maths, 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 (揭示) 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 their 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 a criminal’s home base by combining these patterns with a city’s layout (布局) 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 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 maths. 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 maths 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. "
People tend to believe there is a relationship between______.

选项 A、mathematician and criminologist
B、the location of a crime and the residence of the criminal
C、computer program and profits
D、a census and criminal’s pattern

答案B

解析 本题是细节考查题。题目是:人们倾向于相信______之间有联系。选B的依据是:第二段最后一句:“So,the farther away from the area a crime takes place,the less likely it is that the same criminal did it.”所以,离犯罪现场越远,同一罪犯犯罪的可能性就越低。选项B.犯罪地点和罪犯的住处,与原文意思相符,所以选B。选项A.数学和犯罪学;选项C.计算机程序和利益;选项D.人口普查和犯罪模式。三项都不符合题意,因此应选B。
