　　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 (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 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’m the only one who knows what gold looks like,” he says. “It’s a lot of fun.”

　　49. To find criminals, police usually _________.

　　A. check who are on the crime scene

　　B. seek help from local people

　　C. depend on new mathematical tools

　　D. focus on where crimes take place

　　50. O’Leary is writing a computer program that _________.

　　A. uses math to increase the speed of calculation

　　B. tells the identity of a criminal in a certain area

　　C. provides the crime records of a given city

　　D. shows changes in criminals’ patterns

　　51. By “I’m the only one who knows what gold looks like”, O’Leary means that he _________.

　　A. is better at finding gold than others

　　B. is the only one who uses math to make money

　　C. knows best how to use math to help solve crimes

　　D. has more knowledge of gold than other mathematicians

　　52. What is the main idea of the text?

　　A. Math could help police find criminals.

　　B. Criminals live near where crimes occur.

　　C. Crime records could be used to fight crime.

　　D. Computer software works in preventing crimes.
