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 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.”

Friends play a very important part in everyone’s life. Friendship usually develops during childhood. New friends are made when you progress through school. Those friends that you make as a student can usually last long. Friends influence your development, maturity (成熟) and sense of responsibility. A familiar expression is “you can tell a lot about a person by knowing who his friends are.” Friendship is based on common interests. If you like sports, most of your friends are likely to be athletic. If you enjoy reading and shopping, most of your friends do the same.
Some people call you their friends for the wrong reason. These people are not really friends. They are only “friends” on the outside, not the inside where it counts. They only want to be your friends if it is to their advantage. True friends are there whether you are rich or poor. It is easy to have many so-called “friends” if you are rich. By this time you should be able to separate your friends into the real or the “false”.
True friends are most special. They are also difficult to find. You can consider yourself very lucky if you have one true friend. This friend is eager to help you whenever necessary. He or she knows you would do the same for them. A true friend is someone you can talk to about any subject or problem. You and your true friend have good understanding of each other. True friends support you, take your side, and build up your confidence. “So-called” friends refer to .
| A．fair-weather friends |

Which of the following is NOT true?
| A．You should tell true friends from false ones. |
| B．True friendship is too difficult to find. |
| C．You can share your joys and sorrows with a true friend. |

Introduction
A lot of crime is against bicycles. About 150,000 bicycles are stolen every year and most are never found. You can prevent this happening by following a few careful steps.

A couple had a son eleven years after they married. They were a loving couple and the boy was the apple of their eye. When the boy was around four years old, one day the father was very tired after work so he asked his wife to pick up their son. The mother, who was very busy in the kitchen, totally forgot about it.
Later the boy lost his way on the street. When the son was found missing, the mother hurried to look for him, but she didn’t find him. The mother felt very sad and didn’t know how to face her husband.
When the father went to the police station after hearing that the son was missing, he looked at his wife and said just four words. What do you think the four words were? The husband just said "I love you, darling."
The son was missing. If she had picked him up earlier, this would not have happened. There is no point in blaming (责备) anyone. His wife had also lost her only child. What his wife needed at that moment was comfort and understanding from her husband. That is what the husband gave his wife. Several weeks later, with the help of the police, the couple finally found their lost son. The family’s relationship became stronger over that time.
Sometimes we spend lots of time asking who is to blame. We miss many chances to give each other support and let each other feel the warmth of human relationships. Get rid of all your unwillingness to forgive, selfishness, and fears and you will find the world is much more wonderful. What is the meaning of the underlined phrase “the apple of their eye”
| A．A person who always has a sweet smile in their opinion. |
| B．A person who is as pretty as an apple in their opinion. |

Bright red post boxes, the Queen and queuing—what do they all have in common? They are all important parts of British life. At least I thought so.
However, the ability to queue for long periods of time, once believed to be a traditional characteristic of the British, is no longer tolerated by people in the UK, according to a survey done for British bank Barclays.
Once upon a time, queuing was seen as normal. During World WarⅡ, everyone had to queue up to receive their daily supply of foods. In fact, if you didn't stand up and wait in line with all the others, it was seen as uncivilized.
The famous English double-decker buses, with only one entrance, might also help explain why queuing was seen as a part of British life. Almost always, there is queue to get on.
But perhaps the British are tired of being pushed past by the Spanish, the Italians or the French as they queue up to get a table at a restaurant. The people of these other European countries have more than one entrance to their buses, which explains their more relaxed attitude to the queue.
Two minutes is now the longest time most British people are prepared to stand and wait. But could it be that the Internet, which allows us to carry out tasks quickly, is the main reason why British people are no longer prepared to queue?
"Used to buying without delay, customers are even giving up purchases rather than wait their turn," says Stuart Neal of Barclaycard. "Shoppers are also less likely to queue for long if the item they are buying is of low value."
Perhaps I will have to replace "queuing" with "impatience" in my list of things I relate to the British. What can we learn about the tradition of queuing in Britain?
| A．It was considered a symbol of a civilized behavior. |
| B．It was a long time tradition as old as the Queen. |
| C．It was a product of the slow pace of life. |
| D．It has made the Britain different from other Europeans. |
According to the passage, the British gradually stopped queuing because ______.
| A．they prefer shopping online |
| B．the Internet has changed their way of life |
| C．what they are buying is of low value |
| D．they follow the example of foreigners |
It can be learned from the text that ______.
| A．the British used to buy without delay |
| B．the British have to queue to receive food |
| C．the British get impatient with queuing for long |
| D．the British prefer to take double-decker buses |
The author's main purpose of writing the passage is _______.
| A．to tell us the influence of the Internet on the British ways of life |
| B．to compare the cultural difference between Britain and other countries |
| C．to report his research on the British ways of life |
| D．to talk about the changes in the attitude to queuing in Britain |
