　　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’m the only one who knows what gold looks like,” he says. “It’s a lot of fun.”
　　49. To find criminals, police usually _________.
　　A. check who are on the crime scene
　　B. seek help from local people
　　C. depend on new mathematical tools
　　D. focus on where crimes take place
　　50. 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. provides the crime records of a given city
　　D. shows changes in criminals’ patterns
　　51. 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 best how to use math to help solve crimes
　　D. has more knowledge of gold than other mathematicians
　　52. What is the main idea of the text?
　　A. Math could help police find criminals.
　　B. Criminals live near where crimes occur.
　　C. Crime records could be used to fight crime.
　　D. Computer software works in preventing crimes.

　　45. What does the phrase “green shoots” mean in “Green shoots have begun to appear in different markets”?

　　A. shooting the breeze B. shooting yourself in the foot
　　C. shooting your mouth off D. shooting questions at somebody
　　48. Choose a word to complete the sentence “The ________, which killed a policeman and wounded a passer-by, was reported to have lasted only 13 seconds.”
　　A. shooter B. shoot C. shooting D. shot

A child-like robot, Wakamaru, developed by Mitsubishi Heavy Industries of Japan and combining the roles of nurse, companion and security guard, will soon be in the market to look after the growing number of old people with no one to look after them.
Cameras implanted under the “ eyebrows” of the robot enable it to “see’’ as it moves around in a house. The images can be sent to the latest mobile telephones, which can show the pictures. Wakamaru speaks with either the voice of a boy or a girl. It is also designed to provide companionship, greeting its “ papa”, when he comes home. Based on a vocabulary of around 10 000 words, it is the first household robot which is able to hold simple conversations. It can not only speak, but also understand answers and react accordingly. It will ask“ Are you all right?” if its owner does not move for some time. If the answer is no, or there is no answer, it will telephone preset numbers, send images and work as a speakerphone. It can recognize up to 10 faces. It can be set to remind forgetful people when it is time to take medicine, eat and sleep.
However, like most robots, it cannot climb stairs. Mitsubishi developed Wakamaru from robots which have already been made to go around nuclear power facilities(设施). “ Looking at the ageing of society and the falling birth rate we decided that this could work as a business. We want to offer it as a product that helps society,’’ said the project chief. The developers plan to sell the robot from April next year at between 5,000 and 6,000 pound.
The life expectancy of Japanese women has shot up to almost 85, the highest in the world. At the same time, extended families are being replaced by nuclear families. This has left many Japanese anxious about their elderly parents. Therefore, the technology has gained nation-wide publicity in Japan.
Which of the following is TRUE about Wakamaru?

A．It is used in some nuclear power facilities.

B．It can speak but cannot understand answers.

C．It can go up and down the stairs easily.

D．It can recognize as many as 10 people.

The passage is written with the purpose to ______.
A. introduce a new product
B solve the aging problems.
C. tell people how to use the robot
D show the rapid development of technology
What can be inferred from the passage ?

A．The robot can dial proper numbers for help

B．The robot is likely to have a promising market.

C．The robot enables the Japanese to live longer

D．Many elderly Japanese are anxious about their future

People from East Asia tend to have more difficulty than those from Europe in distinguishing facial expressions--and a new report published online in Current Biology explains why.
Rachael Jack, University of Glasgow researcher, said that rather than scanning evenly
(均匀的) across a face as Westerners do, Easterners fix their attention on the eyes.
"We show that Easterners and Westerners look at different face features to read facial expressions," Jack said. "Westerners look at the eyes and the mouth in equal measure, whereas Easterners favor the eyes and neglect (忽略) the mouth."
According to Jack and her colleagues, the discovery shows that human communication of emotion is more complex than previously believed. As a result, facial expressions that had been considered universally recognizable cannot be used to reliably convey emotion in cross-cultural situations.
The researchers studied cultural differences in the recognition of facial expressions by recording the eye movements of 13 Western Caucasian and 13 East Asian people while they observed pictures of. expressive faces and put them into categories: happy, sad, surprised, fearful, disgusted, angry, or neutral. They compared how accurately participants read those facial expressions using their particular eye movement strategies.
It turned out that Easterners focused much greater attention on the eyes and made significantly more errors than did Westerners. "The cultural difference in eye movements that they show is probably a reflection of cultural difference in facial expressions," Jack said. "Our data suggest that whereas Westerners use the whole face to convey emotion, Easterners use the eyes more and mouth less."
In short, the data show that facial expressions are not universal signals of human emotion. From here on, examining how cultural factors have diversified these basic social skills will help our understanding of human emotion. Otherwise, when it comes to communicating emotions across cultures, Easterners and Westerners will find themselves lost in translation.
The discovery shows that Westerners __

A．pay equal attention to the eyes and the mouth

B．consider facial expressions universally reliable

C．observe the eyes and the mouth in different ways

D．have more difficulty in recognizing facial expressions
