It is very unusual to find anything more than the hard evidence of history—normally, the bacteria in the air eat away at soft materials, like bodies, clothes and things made of wood. Occasionally, things are different.
In 1984, two men made an amazing discovery while working in a bog called Lindow Moss, in the north of England. A bog is a very wet area of earth, with a lot of plants growing in it. It can be like a very big and very thick vegetable soup—walk in the wrong place and you can sink and disappear forever. The men were working when one of them saw something sticking out—a human foot! Naturally, the men called the police, who then found the rest of the body. Was it a case of murder? Possibly—but it was a death nearly two thousand years old. The two men had found a body from the time of the Roman invasion of Britain. Despite being so old, this body had skin, muscles, hair and internal organs—the scientists who examined him were able to look inside the man"s stomach and find the food that he had eaten for his last meal!
Why was this man so well preserved? It was because he was in a very watery environment, safe from the bacteria that need oxygen to live. Also, the water in the bog was very acidic. The acid preserved the man"s skin in the way that animal skin is preserved for leather coats and shoes.
How did he die? Understandably, archaeologists and other scientists wanted to know more about the person that they called “Lindow Man”. His hands and fingernails suggested that he hadn"t done heavy manual work in his life—he could have been a rich man. They found that he hadn"t died by accident. The archaeologists believe that he was sacrificed to three different gods.

When a bird flaps(振翅) its wings, it stirs the air around it and causes it to move indifferent directions. Scientist found in the study that the air creates an upward-moving wave at the tips of the wings, which means that if a bird flies around the wingtips of another bird, it can get a boost(抬高) from the rising air and therefore use less energy to stay in the air.
Apart form the "free ride" strategy, scientists were also surprised to observe that migrating birds timed their wing beats and adjusted their positions in a very precise way to maximize the lifting effect while avoiding areas where the air move downward.
"They"re able to sense what"s going on from the bird in front, where this "good air" is coming from and now how to position themselves perfectly in it," lead researcher Steven Portugal told BBC.
In fact, the "V" formation has long thought to help birds fly more efficiently(效率搞地). A previous study showed that birds" heart rates went down when they were flying together in a "V" formation. Jet fighters were also found to be able reduce their energy use by up to 18% by staying near the wingtips of other jet fighters. Both of these findings led scientists to suspect that the "V" formation had an efficiency purpose, but until now they still lack proof.
"For scientists, the new study provides an insight into an interesting natural phenomenon. But it could mean even more for aircraft companies — helping them understand how they can imitate that with their plane formations to save fuel, said Portugal."

Controlled burns are often employed by government authorities to reduce fuel buildup,and clean up the fallen leaves,and thus,prevent the spread of forest fires to a vast area.Regular controlled burns can also help maintain biodiversity(生物多样性),as the smoke and heat produced in the process can facilitate(促进)the growth of seeds of certain plant species.Apart from these,responsible human behavior can help reduce the number of forest fires to a great extent.In fact,we can reduce the number of wildfires dramatically by not leaving behind any source of fire in the forest.
Forest fires can affect climate and weather to a great extent,besides causing severe damage to valuable trees.Wildfires can increase the level of greenhouse gases(water vapor, carbon dioxide,etc),and therefore increase pollution and global warming.However, they are also an important part of the ecosystem,and many plants depend on the heat and smoke generated by wildfires for their growth and reproduction.But large wildfires can cause extensive damage to the ecosystem,which again highlights the importance of effective control and prevention of forest fires·

According to the US Food and Drug Administration, nearly 90 percent of people worldwide consume about 200 milligrams of caffeine each day. That" s equivalent to about one strong cup of coffee a day. Writing in " Nature Neuroscience" , Johns Hopkins University researchers say their findings show that caffeine strengthens certain memories for up t0 24 hours after being taken in.
" We"ve always known that caffeine has cognitive-enhancing effects (促智效果) , but its ,particular effects on strengthening memories and making them resistant to forgetting has never been examined in detail in humans, " said senior author of the paper Michael Yassa. " We re- port for the first time a specific effect of caffeine on reducing forgetting over 24 hours. " Conducting a double-blind trial, the researchers worked with a test group of people who didn"t regularly consume caffeinated products. Five minutes after studying a series of images, the test subjects were given either a placebo(无效对照剂) or a 200-milligram caffeine tablet.
To check the caffeine levels of their test subjects, the research team took saliva samples (唾液样品) from them before they took their tablets and again one, three and 24 hours after- wards.
Both groups of test participants ( those who took the placebo and those who took the caffeine tablet) were tested the following day to see if they could recognize the images they" d seen the previous day.
The test included showing the test subjects another series of images that included some new images , those that were shown the previous day, as well as other images that were similar, but not the same as those they had viewed earlier.
The researchers found that more members of the group who were given the caffeine tablets were able to correctly identify some of the new images as " similar" to previously viewed images rather than incorrectly identifying them as the same.
"We also know that caffeine is associated with health and longevity(长寿) and may havesome protective effects from cognitive decline like Alzheimer" s disease (阿尔茨海默症). " said Yassa.

Most of the technology is available now, but convincing more people that they don"t need to read a newspaper is the next step. But resistance to computer newspapers may be stronger from within journalism. Since it is such a cultural change, it may be that the present generation of journalists and publishers will have to die off before the next generation realizes that the newspaper industry is no longer a newspaper industry. Technology is making the end of " traditional newspapers unavoidable.
Despite technological advances, it could take decades to replace newsprint with computer screens. It might take 30 t0 40 years to complete the changeover because people need to buy computers and because newspapers have established financial interests in the paper industry.

A.They are cheaper than traditional newspapers. |
B.They are more convenient to read. |
C.You can choose the kind of voice you want to hear. |

Groundhog Day(土拔鼠节),falls on the 2nd of February every year.It is observed in the United States and Canada.While this day may be a public holiday and a bank holiday,it is not a compulsory holiday declared by the government.But this is not so for all the states.State-wise holidays may vary.
Ever heard of Punxsutawney Phil? Groundhog Day is observed because of this groundhog.The day is indeed about a groundhog.Punxsutawney is the name of an apparently weather forecasting groundhog.He lives in his burrow(洞穴)on Gobler’s Knob,Punxsutawney in Pennsylvania,for a short period before the 2nd of February every year.On the 2nd of February,Phil comes out from his burrow and looks for his shadow.If he sees his shadow and goes back into the burrow,then America will have an extended winter of six weeks,But if he cannot see his shadow,and he remains outside.It means winter will soon end and spring will arrive very shortly .Phil has been‘predicting’the length of winter in this manner for almost a century and they have always been almost 100% accurate.
Groundhog Day is celebrated in some parts of the USA and Canada.The largest celebration is held at Punxsutawney,Pennsylvania.People come in scores to visit Punxsutawney Phil.They wait eagerly, camping days in advance,to see the small groundhog appear from his burrow,check for his shadow and either go back in or stay out.People cheer when they hear it is time for winter to end and celebrate by eating sweets and singing and dancing.Today.the Groundhog Day is a widespread tradition and an exciting event.
