Where did all the tigers go? That’s what Indian Prime Minister Manmohan Singh wants to know. India’s Sariska Project Tiger Reserve, once home to 26 tigers, is now home to none. Singh has ordered a police investigation into the   39 ，and created a new taskforce to save the   40  animals.
Tigers are an endangered species(物種). 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 (偷獵者) 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  that 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.

Against the supposition（假設(shè)）that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.
This finding suggests that taking steps to prevent northern forest to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.
This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.
Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧）levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.
“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.
小題1:According to the new findings, taking steps to prevent northern forest fires may _______.
   
A．result in a warming climate
B．cause the forest fires to occur more frequently
C．lead to a longer fire season
D．protect the forests and the environment there
小題2: The following are all the immediate effects after a forest fire EXCEPT _________.
A．large amounts of greenhouse gases enter the atmosphere
B．the levels of ozone which is a type of oxygen increase
C．snow on the ground mirrors more sunlight back into space
D．a(chǎn)shes from the fire fall on the ice surface and take in more radiation from the sun
小題3:Earlier studies about northern forest fires _________.
A．a(chǎn)nalyze all aspects of how northern fires influence climate
B．indicate that forest fires will pollute the atmosphere
C．suggest that people should take measures to protect environment
D．suggest that the fires will speed up climate warming
小題4:The underlined part “soaked up” in the last paragraph most probably means ________.
A．releasedB．a(chǎn)bsorbedC．createdD．distributed
小題5:From the passage we can draw a conclusion that forest fires in Alaska, Canada and Siberia may __________.
A．warm the climate as the supposition goes
B．a(chǎn)llow more snow to reflect more sunlight into space and thus cool the climate
C．destroy large areas of forests and pollute the far-off sea ice
D．help to gain more energy rather than release more energy

In the 1960s, medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful events. They appreciated the tricky point that any major change can be stressful. Bad events like “serious illness of a family member” were high on the list, but so were some helpful life changing events like marriage.
When you take the Holmes Rahe you must remember that the score does not show how you deal with stress -- it only shows how much you have to deal with. And we now know that the way you deal with these events dramatically affects your chances of staying healthy. By the early 1970s, hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow the research got boiled down to a memorable message. Women’s magazines ran titles like “Stress causes illness.”
If you want to stay physically and mentally healthy, the articles said, avoid stressful events. But such simplistic advice is impossible to follow. Even if stressful events are dangerous, many -- like the death of loved one--are impossible to avoid. Moreover, any warning to avoid all stressful events is a prescription for staying away from chances as well as trouble. Since any change can be stressful, a person who wanted to be completely free of stress would never marry, have a child, take a new job or move. The idea that all stress makes you sick also takes no notice of a lot of what we know about people. It supposes we're all vulnerable and not active in the face of the difficult situation. But what about human ability and creativity? Many come through periods of stress with more physical and mental strength than they had before. We also know that a long time without change or challenge can lead to boredom and physical and mental pressure.
小題1:.
The score of the Holmes Rahe test shows ____ .
A．how you can deal with life changing events
B．how helpful events can change your life
C．how stressful a major event can be
D．how much pressure you are under
小題2:.
. Which of the following expressions has the meaning most close to the underlined phrase “got boiled down to” in paragraph two ?
A．was argued aboutB．made clear
C．was concentrated onD．put an end to
小題3:.
. The studies on stress in the early 1970s led to ____ .
A．popular avoidance of stressful jobs
B．great fear over the mental disorder
C．a(chǎn) careful research into stress related illnesses
D．widespread worry about its harmful effects
小題4:.
Why is “such simplistic advice ”(Line 2, Para.3) impossible to follow?
A．No one can stay on the same job for long.
B．More effective ways have been found to get rid of stressful events.
C．People have to get married some day.
D．You could be missing chances as well.
小題5:.

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.”
小題1:
To find criminals, police usually ______.
A．focus on where crimes take placeB．seek help from local people
C．depend on new mathematical toolsD．check who are on the crime scene
小題2:
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
小題3:
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
小題4:
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.

Compared to people with bad attitudes，people who are cheerful and relaxed are less likely to suffer from colds，according to a new study.“It’s possible that being upbeat helps the body fight illnesses，” says Sheldon Cohen，the study’s lead researcher from Carnegie Mellon University (CMU) in Pittsburgh.
In a previous（先前的） study，Cohen and his colleagues put cold­causing viruses into the noses of 334 healthy adults. People who tended to be cheerful and lively were least likely to develop sniffles，coughs，and other cold symptoms. People who showed positive feelings were also less likely to mention symptoms to their doctors，even when medical tests detected those symptoms.
Those findings were interesting，but they didn’t prove that a person’s attitude affects whether he or she gets sick. Instead，it was still possible that a person’s underlying personality is what matters. Evidence suggests，for instance，that certain people are naturally more likely to be outgoing and optimistic，with high self­esteem and a sense of control over life. This would mean that who we are，not how we feel，ultimately decides our chances of catching colds.
To figure out which mattered more (personality or emotions)，the CMU team interviewed 193 healthy adults. The researchers talked to each person over the phone every evening for 2 weeks. At the end of the interviewing period，people got nose drops that contained either cold or flu viruses. Then，each person stayed in an isolated room for 5 or 6 days. The results showed that everyone in the study was equally likely to get infected. Their symptoms，however，differed depending on the types of emotions that they had reported over the previous 2 weeks. Among those who reported good moods and had been infected with the flu virus，for example,28 percent developed coughs and stuffy noses. On the other hand，those symptoms struck 41 percent of people who had been less upbeat.
小題1:
What would be the best title for the passage?
A．Smiles Turn away Colds
B．An Interesting Way to Beat Colds
C．Be Outgoing and Optimistic to Fight Colds
D．What Matters More，Personality or Emotions?
小題2:
In the previous study，people who showed positive feelings______.
A．didn’t catch colds as often
B．developed cold symptoms more slowly
C．were less likely to have cold symptoms detected
D．were less likely to feel cold symptoms
小題3:
What mainly decides our chances of catching colds according to the new study?
A．Personality.B．Self­esteem（自尊）.C．Emotions.D．Attitudes.
小題4:
The underlined word “symptoms” probably means________.
A．something that causes cold
B．something that results in cold
C．signs that something exists，especially something bad
D．changes in your body or mind that show that you are not healthy

When Gretchen Baxter gets home from work as a New York City book editor, she checks her Blackberry (黑莓手機) at the door. ‘I think we are attached to these devices in a way that is not always positive,’ says Baxter，who’d rather focus at home on her husband and 12-year-old daughter. ‘It’s there and it beckons (召喚). That’s human nature (but)…we kind of get crazy sometimes and we don’t know where it should stop.’
Americans are connected at unprecedented (前所未有的) levels一93% now use cell phones or wireless devices；one third of those are ‘smart phones’ that allow users to browse the Web and check e-mail，among other things. The benefits are obvious: checking messages on the road，staying in touch with friends and family，efficiently using time once spent waiting around. The downside：often，we’re effectively disconnecting from those in the same room.
That's why，despite all the technology that makes communicating easier than ever，2010 was the Year We Stopped Talking to One Another. From texting at dinner to posting on Facebook from work or checking e-mail while on a date，the connectivity revolution is creating a lot of divided attention，not to mention social anxiety. Many analysts say it's time to step back and reassess.
‘What we’re going to see in the future is new opportunities for people to be plugged in and connected like never before,’ says Scott Campbell. ‘It can be a good thing，but I also see new ways the traditional social fabric (社會結(jié)構(gòu)) is getting somewhat torn apart.’
Our days are filled with beeps and pings·----many of which pull us away from tasks at hand or face-to-face conversations. We may feel that the distractions are too much，but we can’t seem to stop posting，texting or surfing.
‘We're going through a period of adjustment and rebalancing,’ says Sherry Turkle and she wants to remind people that technology can be turned off.
‘Our human purposes are to really have connections with people,’ she says. ‘We have to reclaim it. It’s not going to take place by itself.’
小題1:What can be the best title for the passage?
A．2010: The year technology developed quickly.
B．2010: The year technology sped up our life pace.
C．2010: The year technology replaced talking.
D．2010: The year technology made communicating easier.
小題2:According to Paragraph l，Gretchen Baxter thinks_________.
A．the new technology always influences people’s life in a positive way
B．the new technology is so tempting that she could even put her daughter and husband behind
C．it is encouraging to see progress on the new technology every year
D．people are too dependent on the new technology to let go
小題3:Which of the following is TRUE according to the passage?
A．The wide use of mobile devices has nothing to do with the ‘traditional social fabric’.
B．Mobile devices play a less important part in American life.
C．Mobile devices create a lot of divided attention and social anxiety.
D．Many analysts speak highly of the wide popularity of mobile devices.
小題4:What can be inferred from the last paragraph?
A．Something must be done to get connection with people in reality again·
B．Using mobile services can help people get connection with each other.
C．Mobile services have a strong impact on people’s life.
D．The connection with people can happen naturally.
