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.

When we donate blood, a small amount is usually taken in advance for at least ABO and Ph systems typing. If you are O+, the O is your ABO type and the + is your Rh type. It is possible to be A, B, AB, or O as well as Rh + or Rh-.
The ABO system was discovered by Karl Landsteiner in the early 1900s. He was awarded the Nobel Prize for his achievements. There are four basic types of blood in the ABO system: A, B, AB and O. Everybody is born with one of these four types of blood. We get blood type, just like hair color and height from parents. Because of the substances(物質(zhì)) contained in each type, the four groups must be transfused carefully, If two different blood types are mixed together, it may put a person into an extremely dangerous situation. Basically, A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. In an emergency, type O blood can be given because it is most likely to be accepted by all blood types, so it is often called the universal donor. However, there is still a risk. For the opposite reason, AB is sometimes called the universal receiver. However, because there can be so many reactions in the blood bank of the hospital.
There is a relationship between your blood type and your nationality. Among the Europeans, about 45 percent have type O while 42 percent have type A. The rarest is type AB. Other races have different percentage. For example, some American Indian groups have nearly 100 percent type O out of 100 donors in the world…
84 donors are Rh+ |
16 donors are Rh- |
38 are O+ |
7 are O- |
34 are A+ |
6 are A- |
9 are B+ |
2 are B- |
3 are AB+ |
1 is AB- |
1. Which of the following shown the correct relationships in blood transfusions?
A B A B A B A B
AB O AB O AB O AB O
A B C D
2. The underlined word “transfuse” most probably means ________.
A. to put the blood into a container
B. to move the blood from one place to another K^S*5U.C#O
C. to put the blood of one person into the body of another
D. to give power to another person
3. The writer suggests that the third most common blood type among the Europeans is ______.
A. B B. A C. AB D. O
4 The text mainly tells us ______.
A. about the basic types of human blood
B. what kind of blood is the most common
C. about Karl Landsteiner who won the Nobel Prize
D. the relationship between blood type and nationality

Eat to Excel
How fit are you? Do you look after yourself? Do you eat healthily or do you eat anything you like? Premier League football club Aston Villa are encouraging their players and local children to eat healthy food. They know that what you eat is the key to success.
How fit is a footballer?
Could you run ten kilometers in 90 minutes? A professional footballer can. Footballers have to be strong, quick, skillful and creative in their moves. Every Premier League club makes sure it has a good coaching scheme and a well-planned fitness program. They also ensure that players have the practice and training that will prepare them for matches. What else do you think clubs pay special attention to? A good stadium? Anything else? What about the food they eat?
Eating the right thing
A good diet is a fundamental part of sport these days. Aston Villa manager Martin O’Neill’s sport and health experts have chosen a secret weapon --- organic food (food grown without chemicals). Fitness manager Jim Henry eats with his players and said: “I chose to switch to organic food for Aston Villa because I’ve read studies showing that organic food has higher levels of vitamins, minerals and antioxidants.” He believes that the best way to get these is to eat the very best fresh food.
What to eat after the match
Head chef at Aston Villa, lan Edge, feeds players with the best food as soon as they finish an away match. He says: “Food is very important to sports stars and particularly after a game. There is an hour of opportunity when they need to eat to get the best muscle strength, so I hand out meals on the coach on the way home. If we can make one per cent difference to the players by using organic food, then it is worth it.”
Teaching healthy eating
Everyone at Aston Villa enjoys organic food at their training ground. But the club is also worried about the unhealthy diet among local children who prefer sweets and unhealthy fast food. As part of their work in the community, Aston Villa has opened up their kitchen and invited children from local schools to come and learn how to cook with the help of the Villa head chef. Villa midfielder, Nigel ReoCoker, visited the children on the opening day. “The kitchen promotes healthy eating and a healthy lifestyle.” he said.
A final word from the kitchen
Head chef Ian says: “Footballers know how important food is to their profession and nine times out of ten, they go for the healthiest option.” Do you watch your diet? If you do and you keep yourself fit, you can be a winner!
