Black Box
You never see them, but they're with you every time you fly. They record where you're going,how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to resist almost any disaster makes them seem like something out of a comic (漫畫) book.They're known as the black box.
When planes fall from the sky, as a Yemeni airliner did on its way to the Comoros Islands in the Indian Ocean on June 30, 2009, the black box is the best method for identifying what went wrong. So when a French submarine(潛水艇) discovered its homing signal five days later, it marked a huge step toward determining the cause of the disaster in which 152 passengers were killed.
In 1958. Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first model for a black box, which became a requirement on all US commercial flights by 1960. Early models often failed to resist crashes, however, so in 1965 it was completely redesigned. That same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to be easier to see.
Modem airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help experts reconstruct the aircraft's final moments. The boxes can resist powerful force and temperatures up t0 2,OOOoF. They're also able to send out signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447 , which crashed near Brazil on June 1 , 2009 , are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.

Getting kids to share their toys is a never-ending battle, and forcing them to do so never seems to help. New research suggests that allowing children to make a choice to sacrifice their own toys in order to share with someone else makes them share more in the future. The new findings are published in Psychological Science.
These experiments were conducted by psychological scientists, Nadia Chernyak and Tamar Kushnir of Cornell University. They found that sharing things with others when they are given a difficult choice leads children to think of themselves as people who like to share. It also makes them more likely to act in a pro-social （親社會的）manner in the future.
Previous research has explained why rewarding children for sharing can backfire. Children come to think of themselves as people who don't like to share since they had to be rewarded for doing so. Because they don't view themselves as "sharers", they are less likely to share in the future.
Chernyak and Kushnir were interested in finding out whether freely chosen sacrifice might have the opposite effect on kids' willingness to share. To test this, the researchers introduced five-year-old children to Doggie, a sad puppet. Some of the children were given a difficult choice: Share a precious sticker（貼紙） with Doggie, or keep it for themselves. Other children were given an easy choice between sharing and putting the sticker away, while children in a third group were required by the researcher to share.
Later on, all the children were introduced to Ellie, another sad puppet. They were given the option of how many stickers to share (up to three). The kids who earlier made the difficult choice to help Doggie shared more stickers with Ellie. The children who were initially faced with an easy choice or who were required to give their sticker to Doggie, on the other hand, shared fewer stickers with Ellie. Therefore, children did not benefit from simply giving something up, but rather from willingly choosing to give something up of value.
“You might imagine that making difficult, costly choices is demanding for young children or even that once children share, they don’t feel the need to do so again,” Chernyak says. “But this wasn't the case: once children made a difficult decision to give up something for someone else, they were more generous, not less, later on.” Chernyak concludes.
【小題1】_______ helps children to share more in the future.
| A．Rewarding children for sharing |
| B．Forcing children to share |
| C．Allowing children to share precious things willingly |
| D．Allowing children to share what they don’t need |
| A．have an opposite effect | B．serve as a push |
| C．cause anger | D．a(chǎn)void taking things back |
| A．they regret what they did | B．it’s not their own choice |
| C．Ellie is not as sad as Doggie | D．they like to share with a real person |
| A．parents will never find a way to get children to share toys |
| B．a(chǎn) gift should be given to make up for children’s sacrifice |
| C．children pretend to be generous when they are being observed |
| D．making difficult choices may influence sharing behavior |

Koala bears as pets might be appealing to many of us. However, there are quite a few points to consider even before thinking of adopting one.
Koala bears are one of the most lovely Australian animals. In certain cases where the koala has been raised by hand, they have turned out to be quite affectionate pets. These people tied a piece of fur to a pillow and placed it beside a joey (a baby kola) as a substitute (替代物) for the mother koala. This trick seemed to work well with the baby koala. However, it is a known fact that human handling causes stress to koalas. In my personal opinion, this aspect clouds the fact that koala bears can be tamed (馴服).
In Australia the koala is a priority animal as far as conservation status assessment is concerned. It was hunted to near extinction (滅絕) for its fur. In fact the koala had been wiped out from South Australia in the 1920s. However, rehabilitation efforts have brought the animal back in the state. As for the Australia government, the koala is not a threatened animal, but the US government does list the koala as one.
Although they may live in 40 to 60 kinds of eucalyptus trees, they prefer only 10 to 14 specific kinds. Koalas sleep for most part of the day, which is about 16 to 18 hours, and for most of their waking hours all they do is eat. Koala bears eat the leaves of eucalyptus trees. A full-grown koala can eat almost 2 to 3 pounds of leaves in a day. Despite their slow movements and sweet look, koala bears can be vicious when hungry. Other than this, there are the stress caused to koalas due to human handling and the fights that start in koalas.
Almost everyone finds koalas lovely in the zoo. However, as far as having koala bears as pets is concerned, there are legal issues to consider. Other than that, being able to provide for its diet and habitat is another point that needs some attention before any law legalizing their adoption as pets is passed.
【小題1】What’s the author’s attitude towards people raising the koala?
| A．Optimistic. | B．Grateful. | C．Cautious. | D．Enthusiastic. |
| A．To get its fur. | B．To eat its meat. | C．To wipe it out. | D．To have it for fun. |
| A．fierce and dangerous | B．patient and friendly |
| C．a(chǎn)fraid and defensive | D．lovely and interesting |
| A．koala bears tend to live in groups |
| B．koala bear care can be very demanding |
| C．koala bears are not particular about their food |
| D．koala bears are the No. 1 threatened animal in the US |

Electrical devices（儀器）could soon use power make by human energy. Scientists say they have developed an experimental device that produces electricity from the physical movement of a person walking . British scientist Max Donelan and other scientists in Canada and the United States developed the device.
The device connects to a person’s knee. As the person walks, the device captures energy each time the person slows down. To do this , the device helps with the slowing sown movement of the leg. The movements of the walking person push parts of a small machine that produces electricity. Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute. Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.
There are several possible uses for the device . Developers say it could help people who work in areas without electricity to operate small computers. The device could also be used in hospitals to operate heart pacemakers（起博器）. It could even be used to assist in the movement of robotic arms and legs.
The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy. But the researchers hope to make a lighter, less costly version. An improved version should be ready in one year.
The developers hope the device will one day help developing countries. Nearly twenty five percent of people around the world live without electric power.
A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania. He created a bag carried on a person’s back that also produces power from walking. The knee device does not produce as much electricity as the bag . But the bag requires the walker to carry a load of twenty to thirty kilograms.
【小題1】The second paragraph mainly talks about .
| A．who developed the device |
| B．how the device works |
| C．several possible uses for the devices |
| D．how much electricity the device can produce |
| A．It is too heavy for the walker to bear |
| B．It is too complex for people to use |
| C．It is too expensive for most people to afford |
| D．It will slow down one’s walking speed. |
| A．produces power without adding more loads to the walker |
| B．can produce more power in a much shorter time |
| C．needs to be equipped with a battery |
| D．can help the walker walk faster |
| A．help housewives operate the washing machine |
| B．make it much easier for us to go online |
| C．produce more electricity than that invented by Larry Rome |
| D．be applied to operate heart pacemakers |
| A．First device powered by walking will soon be on the market |
| B．Advanced technology brings in a new way to operate heart pacemakers |
| C．Device gives new meaning to the idea of power walking |
| D．Human energy will become a main source of electricity |

A regular drop in the sun’s radiation(輻射) can cause unusually cold winters in parts of North America and Europe, scientists say, a finding that could improve long-range forecasts and help countries prepare for snowstorms.
Scientists have known for a long time that the sun has an 11-year cycle during which radiation measured by sunspots on the surface reaches a peak then falls. But explaining a clear connection to weather is harder.
“Our research confirms the observed connection between solar change and regional winter climate,” lead author Sarah Ineson of the UK Met Office told the reporters in an email. The study was published in the magazine Nature Geoscience on Monday.
The researchers found that the reducing of ultraviolet(UV，紫外線) radiation from the sun can affect high-altitude wind patterns in the Northern Hemisphere(半球), causing cold winters.
“While UV levels won’t tell us what the day-to-day weather will do, they show us the bright future of improved forecasts for winter conditions for months and even years ahead. These forecasts play an important role in long-term possibility planning,” Ineson, a climate scientist, said.
Ineson and colleagues from Imperial College London and the University of Oxford used satellite data that more accurately(精確的) measures UV radiation from the sun and found a much greater change than previously thought.
They found that in years of low activity, unusually cold air forms high in the atmosphere over the tropics. This causes a redistribution(重新分配) of heat in the atmosphere, making easterly winds that bring freezing weather and snowstorms to northern Europe and the United States and milder weather to Canada and the Mediterranean.
When solar UV radiation is stronger, the opposite occurs.
More study was needed, though. A key uncertainty in the experiment lay in the satellite data used, because it covers only a few years. “So questions remain concerning both accuracy(精確) and also applicability to other solar cycles,” she said.
【小題1】The new finding claims cold winters in the North Hemisphere can be caused by ______.
| A．a(chǎn) sharp rise in the amount of sunspots |
| B．a(chǎn) drop in the sun’s UV radiation |
| C．a(chǎn) complex computer model simulation |
| D．a(chǎn) clear link between the sun and the earth |
| A．UV radiation can affect high-altitude wind patterns |
| B．there’s a clear connection between the sun’s activity and weather |
| C．the sun’s radiation reaches a peak every eleven years |
| D．they can predict day-to-day weather conditions from UV levels |
| A．Canada and the Mediterranean will have milder weather. |
| B．The whole Northern Hemisphere will suffer from extreme winter days. |
| C．Freezing cold weather will appear in northern Europe. |
| D．Burning hot weather will appear in the United States. |
| A．researchers have analyzed the data collected in eleven years |
| B．long-term weather conditions can be accurately predicted depending on UV levels |
| C．the research doesn’t seem correct and true enough due to limited satellite data used |
| D．climate scientists have just begun their research in severe weather forecast |

Researchers found that people become happier and experience less worry after they reach the age of fifty. In fact, they say by the age of eighty-five, people are happier with their life than they were when they were eighteen years old.
Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of twenty-two and twenty-five. The findings showed that stress levels dropped sharply after people reached their fifties. Happiness was highest among the youngest adults and those in their early seventies. The people least likely to report feeling negative emotions were those in their seventies and eighties.
The findings appeared in the Proceedings of the National Academy of Sciences. Researchers say they do not know why happiness increases as people get older. One theory is that, as people grow older, they grow more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.
The researchers considered possible influences like having young children, being unemployed or being single. But they found that influences like these did not affect the levels of happiness and well-being related to age.
The study also showed that men and women have similar emotional patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men.
【小題1】What is the best title of the passage?
| A．The older a person is, the more stressed he feels. |
| B．The more lighthearted a person is, the happier he is. |
| C．The older a person is, the more clever he grows. |
| D．The older a person is, the happier he grows. |
| A．only when people get older, will they feel happier |
| B．older people usually have no worries in their life |
| C．stress levels among the youngest are the highest of all |
| D．older people are more likely to be thankful in life |
| A．When people get older, they can’t remember bad experiences. |
| B．When people get older, they have no young children to care about. |
| C．When people get older, they learn to adjust their feelings. |
| D．When people get older, they don’t care about their feelings. |
| A．A Gallup organization. |
| B．A popular science magazine. |
| C．A university in New York. |
| D．A research institution |
| A．Advice to the young people on how to keep happy. |
| B．Advice to the old people on how to live longer. |
| C．Why women at all ages are more sad, stressed and worried. |
| D．Why people will grow happier with their ages. |

Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings. The noise that affect sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.
Decibels（分貝）measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect.
Some scientists have proposed setting a noise limit of one hundred and twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales.
A team of American and Canadian scientists discovered that loud noises can seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales’ ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected.
Many researchers whose work depends on ocean sounds object to a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research.
Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.
【小題1】According to the passage, which of the following is increasingly dangerous to sea creatures?
| A．The man-made noises. |
| B．The noises made by themselves. |
| C．The sound of earthquakes. |
| D．The sound of the ice-breaking. |
| A．They are deaf to noises. |
| B．Noises at a certain level may hurt them. |
| C．They are easily confused by noises. |
| D．Noises will limit their ability to reproduce. |
| A．prevent them from doing their research work |
| B．benefit them a lot in their research work |
| C．do good to their health |
| D．increase the industrial output |
| A．They will try their best to decrease noise. |
| B．They will work hard to cut down noise pollution. |
| C．They will study the effect of different noises. |
| D．They will protect animals from harmful noises. |

Man, a land animal. But he is also closely tied to the sea. Throughout history the sea has served the needs of man. The sea has provided man with food and a convenient way to travel to many parts of the world. Today, nearly two-thirds of the world’s population live within 80 kilometers of the sea coast.
In the modern technological world, the sea offers many resources to help mankind survive. Resources on land are beginning to be used up. The sea, however, still can be hoped to supply many of man’s needs.
The list of riches of the sea yet to be developed by man’s technology is big. Oil and gas explorations have been carried out for nearly 30 years. Valuable amounts of minerals exist on the ocean floor ready to be mined.
Fish farming promises to be a good way to produce large quantities of food. The culture of fish and shellfish (貝類動物) is an ancient skill practised in the past mainly by Oriental people, including people in China.
Besides oil and gas, the sea may offer new sources of energy. Experts believe that the warm temperature of the ocean can be used in a way similar to the steam in a steamship. Ocean currents and waves offer possible use as a source of energy.
Technology is enabling man to explore ever more deeply under the sea. The development of strong, new materials has made this possible.
The technology to harvest the sea continues to improve. Experts believe that by the year 2020 the problems that prevent us from exploiting（開發(fā)） fully the food, minerals, and energy sources of the sea will be largely solved.
【小題1】Valuable amounts of minerals are ______.
| A．in the ocean water | B．in the warm ocean water |
| C．on the sea coast | D．on the ocean floor |
| A．the sea resources have largely been used up |
| B．the sea, in the broad sense, has not yet been developed |
| C．the problems that prevent us from using the food, minerals, and energy sources of the sea have already been solved. |
| D．by the year 2020 , the technology will be good enough to exploit all the sea resources |
| A．the people in Asia | B．African people |
| C．European people | D．American people |
| A．Sea Harvest | B．Sea Food |
| C．Technology for Exploiting the Sea | D．Man and the Sea |

About ten men in every hundred suffer from color blindness in some way. Women are luckier, only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!
There are different forms of color blindness. In some cases a man can not see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green - a strange world indeed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods” but these are used for seeing when it is nearly dark. They show us shape but no color.
Some insects have favorite colors. Mosquitoes (蚊子) like blue but do not like yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible (看不見的) colors around.
【小題1】Why do some people say it is safer to be driven by women?
| A．Women are more careful. |
| B．There are few color-blind women. |
| C．Women are fonder of driving than men. |
| D．Women are weaker but quicker in thinking |
| A．color and its surprising effects |
| B．women being luckier than men |
| C．danger caused by color blindness |
| D．color blindness |
| A．tell orange from yellow |
| B．see in weak light |
| C．kill mosquitoes |
| D．tell different shapes |
