    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. "
It can be inferred from the last paragraph that O’Leary______.

选项 A、will further use math in studying crimes and criminals
B、will find out criminal’s patterns change over time
C、will analyze the connection between math and criminology
D、let people know how likely it is that they will become victims of crime

答案A

解析 本题是细节推理题。题目是:从最后一段,我们可以推理出奥利里______。选A的依据是:最后一段:“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.”说明奥利里认为用数学研究犯罪学很有趣,像一座金矿,并且他很享受其中的乐趣。选项A.他要进一步将数学应用于研究犯罪和罪犯,符合题意,所以A是正确答案。选项B.会发现犯罪模式随时间改变;选项C.会分析犯罪学和数学之间的联系;选项D.让人们知道他们成为犯罪事件受害者的可能性有多大,都不符合原文意思,因此只能选A。
