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. "
O’Leary’s program is different from other similar software in that______.

选项 A、it aids the police in solving criminal cases more quickly and easily
B、it carries out a census to get detailed information about a given city
C、it can really combines research with pleasure
D、it uses more maths

答案D

解析 本题是细节考查题。题目是:奥利里的程序和其他近似软件的区别在于______。选D的依据是:第五段第一句:“Other computer programmers have worked on similar software,but O’Leary’s uses more math.”其他计算机程序员也致力于编写相似的软件,但是奥利里的软件应用更多数学知识。选项D.应用更多的数学知识,符合原文意思,所以D是正确答案。选项A.它能帮助警察更快、更容易地破案;选项B.它进行人口普查以获得某一城市的详细信息;选项C.它能将研究和快乐真正地结合在一起,这些都不是奥利里的软件和其他相似软件的区别,因此只能选D。
