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.”

举一反三
David Kelly, founder of the Design School Stanford, said, “In the classroom of the future, education will be custom-made for each student. Every child will have a laptop programmed for his or her learning style and speed. At the same time, more students will go out into the community to learn from business owners. And you’ll see more retirees in the schools as teachers.”
A New Way to Pay
Turn your cell phone into a “mobile wallet” and speed through the checkout line. With a smart phone that uses the same technology as “tap and go” cards, you’ll be able to access your financial data fast. You can select a credit or debit card（借记卡）from the screen, and then tap the phone on the checkout console（操纵台；控制台）.
High-Tech Guitar
A 26-year-old Australian designer has inve
nted a brand-new way to be a rock star. The Misa Digital Guitar’s fret board looks like a traditional six-string’s but with no strings attached. There’s a touch pad （垫）where the sound hole 
normally is, and instead of plucking strings,（弹弦） you tap, drag, or brush the pad to “play” the instrument electronically.The Future of Phones
Jason Chen, editor of the website gizmodo.com, makes his prediction. “Data connections will get even faster, and you’ll be linked to your environment by cell phone. Fcr example, wh
en you go on vacation, you can point your phone at a monument（纪念碑） and it will give you information about what you’re looking at.’Needle-Free Vaccines（无针接种）
Boston University researchers are working on a new method of inoculation（接种）—no injection necessary. A mild electrical charge from a small device, shaped like a gun, is used to drive the particles（粒子） into the body. The new idea beats the old needle method.

Showing how much better than other people we are is only one reason we like jokes. Someone may also use a joke to express their anger or their cruelty （残酷）or any other kind of action that is not acceptable to us. We feel free to laugh when we hear about someone sliding on a banana skin. The joke lets us express those attitudes which are usually unacceptable to society. This is probably the reason why some of the jokes，especially those involving cruelty，are so popular with certain people.
Besides，all jokes depend on our enjoyment of laughing at something that is strange and out of place because it’s different from things which are happening around it. The same situation can be either sad or pleasant，depending entirely on how strange and out of place it is. If a girl in a bathing suit falls into a swimming pool，we don’t laugh because nothing unusual has happened. But if a man in a smart suit falls in，the situation is at once unusual in a pleasant way and we laugh. A good joke-teller will always try to build up a situation in which one thing is expected until something unexpected suddenly happens，and so we laugh.
小题1:The underlined word “inferiority” (in Paragraph 1) means ______.
| A．someone that is better than someone else |
| B．something that is better than something else |
| C．someone that is as good as someone else |
| D．something that is not as good as something else |
stotle, all jokes depend mainly on ______. | A．resulting in a sense of success |
| B．showing inferiority in another person or group |
| C．having a good opinion of other people |
| D．making people laugh unexpectedly |
| A．To express those attitudes usually unacceptable to society is one of the reasons we like jokes. |
| B．When people are angry, they would like to hear jokes. |
| C．People who like jokes are usually cruel. |
| D．Showing we are better than other people is the only one reason we like jokes. |
| A．Make an unexpected thing happen in an expected situation |
| B．Make different things happen at the same time. |
| C．Make a sad situation into a pleasant one. |
| D．Make people laugh at something unusual and out of place. |
Doris Leuthard, the Swiss energy minister, said Switzerland would put off plans to build nuclear plants. She said no new ones would be permitted until experts had reviewed safety standards.
Germany will put off “the recently decided extension of the running time of German nuclear plants,” Chancellor Angela Merkel told reporters. “This moratorium（延缓）will run for three months and it will allow for a thorough examination of the safety standards of the county’s 17 nuclear power plants.
The European Union called for a meeting on Tuesday of nuclear safety authorities to assess Europe’s preparedness.
Germany’s foreign minister, Guido Westerwelle, called for a new risk analysis of the country’s nuclear plants, particularly regarding their cooling systems. He is the leader of the Free Democratic Party, which strongly supports nuclear power.
A previous government, led by the Social Democrats, passed a law in 2001 to close all the country’s nuclear plants by 2021. But Mrs. Merkel’s government changed that decision last year to extend the lives of the plants by an average of 12 years.
In Switzerland, Doris Leuthard said she had already asked to analyze the exact cause of the problems in Japan and draw up new or tougher safety standards “particularly in terms of seismic(地震的，与地震相关的) safety and cooling.”
In Russia, the Prime Minister said his government would “draw conclusions from what’s going on in Japan.”
小题1: Where can you most likely read this passage?
| A．In a newspaper. | B．In a magazine. | C．In a science report. | D．In a diary. |
| A．Germany will close all the country’s nuclear plants. |
| B．Germany will hold a meeting of nuclear safety authorities. |
| C．Germany will change the decision made last year. |
| D．Germany will delay the extension of nuclear plants running time. |
| A．The moratorium in Germany will give time to examine the nuclear plants safety standards. |
| B．Switzerland will not build new nuclear plants unless they meet the experts’ safety standards. |
| C．The Social Democrats in Germany shares the same view with the Free Democratic Party. |
| D．Russia will try to learn something from the nuclear power crisis in Japan. |
| A．Watch Out for the Danger of Nuclear Power |
| B．Europe Is against Building Nuclear Plants |
| C．Nuclear Plants in Europe Are Delayed |
| D．Opinions on Nuclear Power Are Opposite |
Edward Norton’s character in the movies Fight Club faces the struggle of jet-lag-induced sleeplessness due to his constant traveling. Sleeplessness is just one of the effects of jet lag, and it can lead to other problems, such as tiredness, memory loss and confusion. That’s not something you should have to fight on a business trip and it certainly won’t make your vacation very enjoyable, either.
Sleeplessness is the biggest problem for travelers that suffer from jet lag. Don’t worry. You can do something to prevent it.
Modify(改变)Your Body Clock
To prevent the effects on your body’s timing that come with crossing time zones, you need to change your body clock sooner, rather than later. You can do this by putting yourself on the same time as your destination time zone before you fly. If you know that you will be traveling to London from the eastern United States, you’ll have a five-hour time difference to deal with. Plan for it.
Avoid Heavy Food and Alcohol(酒精)
Part of the pleasure of flying commercially, especially if you fly business or first class, is taking advantages of the food and drinks. If you want to avoid jet lag, though, you should think twice. Eating heavy food will only make the jet lag worse. It isn’t good to drink alcohol during a flight, either, because it may make you drowsy. Wait until your body adjusts(调整) before you decide to have heavy food or drink alcohol.
小题1:

Tiger
s are an endangered species(物种). Half of the world’s tiger 41 live in India. For years, tigers have been disappearing from India’s national parks, but Sariska may be the last straw. And the government has to react.On Thursday, Singh held the first meeting of 42 officials, wildlife experts, and related leaders, aiming to count the nation’s remaining tigers, and to come up with a plan to keep them safe.
It is not hard to guess why the tigers are disappearing. Poachers (偷猎者) can 43 the big cats for $50,000 each. Tiger skin and bones are popular in Chinese 44 . A single tiger tooth can fetch $120. Recently, a group of poachers admitted killing ten tigers in Sariska and were 45 .
“Indian tiger poaching is probably the biggest conservation problem in modern times.” said Belinda Wright, the head of the Wildlife Protection Society of India.
However, poaching isn’t the only 46 . Many poachers use advanced technologies, like night glasses and long–range binoculars. Forest security officers are paid so 47 th
at few of them bother to track down the poachers. Even if a security guard were to find a poacher, many carry only a stick to make him obey the law.Tiger fans hope that Singh’s plans mean end for the poachers and 48 for the endangered species.
