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(嫌疑犯) 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 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.”

To find criminals, police usually ______.

A. focus on where crimes take place            B. seek help from local people

C. depend on new mathematical tools          D. check who are on the crime scene

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. shows changes in criminals’ patterns

D. provides the crime records of a given city

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 more criminals than other mathematicians

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

What is the main idea of the text?

A. Criminals live near where crimes occur.

B. Math could help police find criminals.

C. Crime records could be used to fight crime.

D. Computer software works in preventing crimes.

L          in nursing homes, as they say, old people                    77.               

can enjoy more benefits             staying at home.                    78.                  

For one aspect, they can have more opportunities to

British English and American English are almost the same. But there are slight differences between British and American English in vocabulary, pronunciation, spelling and grammar.
The first difference between British and American English is in vocabulary. Almost all of the words used in British English and American English are exactly the same. Only a very small number of words are used disparately. For example, Americans would say “apartment”, but the British would say “flat” to talk about the place where they live. In addition to some common words, many idiomatic（惯用的）expressions are different. In England people might say “I’ll ring you up tonight”, but in the US, people might say “I’ll call you up tonight”.
The second difference between British and American English is in Pronunciation. The main difference in pronunciation concerns the vowels（元音）. Some American dialects and some British dialects use vowels in different ways. Sometimes, Americans and the British don’t understand each other’s pronunciation. But most of the time, the British and Americans do understand each other’s pronunciation because most of the sounds of the two dialects are the same.
The third difference is very small. This is the difference in spelling. A few types of words are spelled differently in British and American English. The most common example is in a word like “center”. In British English, this word would be spelled C-E-N-T-R-E, while in American English the same word would be spelled C-E-N-T-E-R. Another example is “or” vs “our”. The word “color”is spelled C-O-L-O-U-R in Britain but C-O-L-O-R in the US.
There are a few differences in grammar, too. The British may say “Have you got..?” while Americans prefer “Do you have..?” An American might say “my friend just arrived”, but a British would say “my friend has just arrived”. Sometimes function words are used differently: the British may say “at the weekend”, but Americans would say “on the weekend”.
