　　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.”

After stepping into the classroom, I glanced round all the students and began my following words. “Thank you” are my    words, which I would like to use to express my deepest    to all of you.

Thinking back to the past 3 years, a lot of things    remain fresh in my memory. I cannot forget your   smile the first time I met you. I cannot forget that you were to    for your being late for class,     when I asked why you were late, you tried to    the fact of buying me a lovely teddy bear for Teacher's Day. I cannot forget your humorous words of breaking     when I was angry about your bad performance. I cannot forget that we share the happiness of success after making great   .

With time going by, I come to    that you are the mirror of my life. The mirror can reflect my past and    my future. Looking through the mirror, I'm more aware of my     and weaknesses.

It is you who made me believe love can be   . It is you who made me realize sometimes in the   of pursuing our dreams, we may    some difficulties and setbacks（挫折）, but if we set up our mind to do it,     is impossible to a willing heart.

So standing in a higher position, I will help you to     the dreams confidently and firmly,     suffering the mistakes I made when I was your age.

, I pray that kind of friendship can stand the test of    and last forever. I pray that you can get good performance in the entrance examination and make your dreams come true.
