    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. "
Which of the following about maths is correct?
选项 A、Few people would link math with crime.
B、It’s difficult for the police to find criminal with maths.
C、The criminal would use maths to break the law.
D、It took a long time to find a solution with math.
答案A
解析 本题是细节考查题。题目是：下面有关数学的描述，哪个是正确的?选A的依据是：第一段第一、二句：“当你想到数学，你可能不会想到违法、破案和寻找罪犯。但马里兰州的数学家想到了……”，我们可以推理出，很少有人会因数学联想到犯罪这个话题，选项A．几乎没人会将数学和犯罪联想到一起，符合题意，是正确答案。而选项B．警察很难用数学找到罪犯；选项C．罪犯会使用数学违法；选项D．用数学找到解决方法要花很长时间，三个选项在原文中都没有提到，因此只能选A。
