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 locati
on 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 geographic
al 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 si
milar 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. |

To find out how the name Canada came about, we must go back to the 16th century. At that time, the French dreamed of discovering and controlling more land across the world. In 1535 Francois I, King of France, ordered a navigator (航海家) named Jacques Cartier to explore the New world and search for a passage to India.
Cartier first arrived at the Gulf of the St. Lawrence, which he wanted to explore. He did not know
what to expect but he hoped that this Gulf was just an arm of the ocean between two islands. If it
was, he would soon be on his way to the Far East. So he sailed upwards along the St. Lawrence
River. However, instead of reaching Asia he arrived at Quebec or Stadacona, as the Indians called
it. It was at this point that the term “Canada” entered the country’s history. Clearly the word
“Canada” came from an Indian word “Kanata”, which means village. Cartier first used it when he
referred to Stadacona or Quebec. What a huge “village” Canada is!
57. What was Cartier ordered to do?
A. To build a new country
B. To find the New World
C. To get in touch with the American Indians
D. To know more about America and find a new way to Asia
58. When Cartier reached the Gulf of St. Lawrence he hoped ________.
A. he had got to the Far East B. it was a water way to the New World
C. it was a water way to the Far East D. he had sailed into the Pacific
59. Which of the following is TRUE according to the passage?
A. Quebec and Stadacona were tow islands.
B. The Indian language for village is Stadacona.
C. Quebec and Stadacona were two villages in Canada.
D. Stadacona was what the Indians called Quebec.
60. Canada was first used to refer to __________.
A. Asia B. the New World C. a village D. Quebec

Do you want to improve the way you study? Do you feel nervous before a test? Many students say that a lack of concentration (注意力) is their biggest problem. It seriously affects their ability to study, so do their test results.
If so, use these tips to help you.
Study Techniques
You should always study in the same place. You shouldn’t sit in a position that you use for
another purpose. For example, when you sit on a sofa to study, your brain will think it is time to relax. Don’t watch TV while you are studying. Experts warn that your concentration may be reduced by 50 percent if you attempt to study in this way. Always try to have a white wall in front of you, so there is nothing to distract (make less concentrated) you. Before sitting down to study, gather together all the equipment you need. Apart from your textbooks, pens, pencils and knives, make sure you have a dictionary. If your study desk or table is needed when you are not studying, store all your equipment in a box beside it .
Your eyes will become tired if you try to read a text which is on a flat surface. Position your
book at an angle of 30 degrees.
Be realistic and don’t try to complete too much in one study period. Finish one thing before
beginning another. If you need a break, get up and walk around for a few minutes, but try not to telephone a friend or have something to eat.
Test-taking Skills
All your hard work will be for nothing if you are too nervous to take your test. Getting plenty
of rest is very important. This means do not study all night before your test! It is a better idea to have a long-term study plan. Try to make a timetable for your study which lasts for a few months.
Exercise is a great way to reduce pressure. Doing some form of exercise every day will also
improve your concentration. Eat healthy food too.
When you arrive in the examination room, find your seat and sit down. Breathe slowly and
deeply. Check the time on the clock during the test, but not too often. Above all, take no notice of everyone else and give the test paper your undivided attention.
54. Which of the following statements is true according to the passage?
A. You should study in a different place every day, so you don’t get bored.
B. Your concentration will improve if you study and watch TV at the same time.
C. Check the time during the exam at a certain time.
D. Staying up all night and studying is tiring, but you will learn a lot using this method.
55. What does the underlined word “it” refer to in the 3rd paragraph?
A. Your study desk or table. B. Your textbook.
C. Your dictionary. D. The equipment you need.
56. What can be inferred from the passage?
A. You shouldn’t look at everyone else during the test.
B. You will have enough energy to deal with your study and exams by eating healthy diet.
C. You’ll concentrate more if there is nothing to distract you.
D. If you feel tired during study, you can walk around for a few minutes.

People in the United States honor their parents with two special days: Mother’s Day, on the second Sunday in May, and Father’s Day, on the third Sunday in June. These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible(有责任感的) citizens. They give love and care. These two days make us think about the changing roles of mothers and fathers. More mothers now work outside the home. More fathers must help with child care.
These two special days are celebrated in many different ways. On Mother’s Day people wear carnations. A red one symbolizes a living mother. A white one shows that the mother is dead. Many people attend religious services to honor parents. It is also a day when people whose parents are dead visit the cemetery(墓地). On these days families get together at home, as well as in restaurants. They often have outdoor barbecues for Father’s Day. These are days of fun and good feelings and memories.
Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are valued more than the ones bought in stores. It is not the value of the gift that is important, but it is “the thought that counts”. Greeting card stores, florists, candy makers, bakeries, telephone companies, and other stores do a lot of business during these holidays.

In New York, there is now a school with no daily lessons, no class teachers, not even a school building. The “school” is a project. It is called “City-as-School” and the name means just that, the city itself is the place where 350 students, between the age of 15 and 18, learn their lessons.
Students choose areas of work which interest them and then they help to do that work. For instance, one girl spends her week in the offices of a Congresswoman — an elected official — helping the public with problems such as pensions(养老金),housing, etc. Then she goes to help in a theatre for a day and she spends one day a week taking first-year courses at college.
City-as-School is 30 years old. The education system in New York accepts it now, as an alternative to final years at school. But can it replace ordinary lessons? Well, students have to pass maths and science exams before they enter the “school”. These subjects are not easy to provide for in “ City-as-School”. Teachers monitor the progress of the students. 80 to 85% of the students go to college (or university, as it is called in Britain) after their time at “City-as-School”. The success rate is high. And the students are enthusiastic about their “school”. They like the responsibility of their work, and the sense of purpose it gives them.
When the students leave “City-as-School”, they don’t have a normal academic education; but they do know a lot about different kinds of work in the city!
53. “City-as-School” is special because it is ________.
A. in New York, one of the most famous cities in the world
B. not a common school we usually see and know
C. a school having special students
D. free of charge for the citizens
54. What do the teachers at “City-as-School” do?
A. To monitor the progress of the students.
B. To give lessons to the students.
C. To evaluate the students’ performance.
D. To protect the students.
55. What is the author’s attitude to “City-as-School”?
