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.”

1.

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

2.

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

3.

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

4.

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.

高二英语短对话简单题查看答案及解析

Many people think of the brain as a mystery. They don't know much about intelligence and how it works. When they do think about what intelligence is, many people believe that a person is born smart, average, or dumb — and stays that way in the whole life. But new research shows that the brain is more like a muscle — it changes and gets stronger when you use it. And scientists have been able to show just how the brain grows and gets stronger when you learn.

Everyone knows that when you lift weights, your muscles get bigger and you get stronger. A person who can't lift 20 pounds when he/she starts exercising can get strong enough to lift 100 pounds after working out for a long time. That's because the muscles become larger and stronger with exercise. And when you stop exercising, the muscles shrink and you get weaker. That's why people say “Use it or lose it！”

But most people don't know that when they practice and learn new things, parts of their brain change and get larger a lot like muscles do when they exercise. Inside the cortex (皮层) of the brain are billions of tiny nerve cells, called neurons. The nerve cells have branches connecting them to other cells in a complicated network. Communication between these brain cells is what allows us to think and solve problems. When you learn new things, these tiny connections in the brain actually multiply and get stronger. The more you challenge your mind to learn, the more your brain cells grow. Then, things that you once found very hard or even impossible to do — like speaking a foreign language or doing algebra (代数) — seem to become easy after learning them for a period of time. The result is a stronger, smarter brain.

Scientists started thinking that the human brain could develop and change when they studied animals' brains. They found out that animals that lived in a challenging environment were more “perspicacious” — they were better at solving problems and learning new things.

1.According to the first paragraph，________.

A. the function of our brain is like that of the muscle

B. until now it's impossible to explain the brain's mystery

C. many people believe one's intelligence is naturally determined

D. one's brain grows stronger as the age increases

2.Training muscles is compared to ________.

A. using the brain

B. connecting things in your brain

C. lifting weights

D. doing research about the brain

3.What is Paragraph 3 mainly about_________?

The complex structure of the brain.

B. How changes in the muscles affect the brain.

C. The importance of the brain.

D. How the brain becomes stronger by learning new things.

4.What does the underlined word “perspicacious” in the last paragraph probably mean_________?

A. Strong.　　　B. Smart.　　         C. Popular.　         D. Active.

5.The paragraph that follows the passage will most probably talk about _______.

A. the differences between animals’ brains and humans’ brains

B. the relation between human brains and muscles

C. scientists’ findings about animals’ brains

D. how to make your brain smarter through self-development

高二英语单项填空中等难度题查看答案及解析

The world was mysterious (神秘的) when I was a child, so miracles (奇迹) were welcome wonders. Now, there doesn’t seem to be space for them in this world I so intelligently understand.

Perhaps it’s from years of working around sick and often dying children, watching time and time again as a child slips away from the arms of a begging mother. I have stopped hoping as the parents around me hope.

I recently cared for a patient near the end of his life. Medically speaking, his situation was hopeless, which made me feel helpless and defeated.

His mother came in to see him. I had prepared myself to support her, imagining she would crumble (崩溃) into a pile of tears.

“Our God is faithful,” she said, with a smile on her face and the sunshine of hope in her eyes.

“Cancer is faithful,” I muttered (嘀咕) in my mind.

“We still believe he can heal him,” she continued, as if she had heard what I was thinking.

I provided updates on his body. In a laundry list of updates, perhaps two things were positive. She thanked me for the information, repeating back the minor positive notes I had given.

I brcame kind of angry. And I wanted to sak, “Do you really not understand the gravity (严重性) of this illness?”

And then, yet again, as if she had heard me, she replied with this: A positive attitude gives us power over our circumstances, rather than allowing our circumstances to have power over us.

I was shocked. Here I was, judging her positive attitude as a fault. I completely disregarded the choice to believe in something more powerful than me, more healing than the doctors on our team. It wasn’t blind faith. It was strength and devotion.

When I came out of the room, tears welling in my eyes, I sat at my computer and looked

down at a small plate of candies she must have left for me on her way into the room. A hand

written note was laid above them: Kate, your devotion is so appreciated, S.

S, it is your devotion that I am appreciating today. Because of you, I am begging again to

believe in miracles.
