While dog keepers realize their dogs can read their moods accurately,scientists have always been a little doubtful.Now thanks to some researchers at the University of Veterinary Medicine in Vienna,Austria,we finally have some convincing evidence.

    For their study,biologist Corson Miller and his team exposed eleven selected dogs to digital images of women that were either angry or happy.Half the dogs were rewarded for touching the screen when shown a happy face,while the other half got their treat for selecting those that appeared angry.

    Interestingly,the dogs were not provided with the entire face.Some dogs were shown only upper halves while the others observed lower halves.That's because the scientists believe humans show their emotions on their entire face.

    After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions,the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face.The researchers concluded the dogs were smart enough to read human emotions.

    They also found those being trained to read angry expressions took a longer time to learn.They guess it may be because dogs find angry faces disgusting,causing them to withdraw quickly.However,once the smart dogs realized they were getting rewarded,the trepidation seemed to disappear.In fact,the dogs had such a good time playing the computer "game" that scientists had a hard time keeping them away from the touch screens after the study was completed.

    The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctl. Since the touchscreen models were all females, this confirmed what has been observed in previous studies-dogs are more efficient at reading facial expressions of people that are the same gender as their owner.

    Thanksgiving Day is a special holiday in the United States and Canada. Families and friends gather to eat and give thanks for their blessing.

    Thanksgiving Day is really a harvest festival. This is why it is celebrated in late fall, after the crops are in. But one of the first thanksgivings in America had nothing to do with a good harvest. On December 4,1619, the Pilgrims from England landed near what is now Charles City, Virginia. They knelt down and thanked God for their safe journey across the Atlantic.

    The first New England Thanksgiving did celebrate a rich harvest. The Pilgrims landed at what is now Plymouth, Massachusetts, in 1620.They had a difficult time and the first winter was cruel. Many of the Pilgrims died. But the next year, they had a good harvest. So Governor Bradford declared a three­day feast (盛宴).The Pilgrims invited Indian friends to join them for their special feast. Everyone brought food.

    In time, other colonies (殖民地) began to celebrate a day of thanksgiving. But it took years before there was a national Thanksgiving Day. During the Civil War, Sarah Josepha Hale persuaded Abraham Lincoln to do something about it. He proclaimed (宣布) the last Thursday of November 1863 as a day of thanksgiving.

    Today, Americans celebrate this happy harvest festival on the fourth Thursday in November. Canadians celebrate Thanksgiving Day in much the same way as their American neighbours. But the Canadian Thanks­giving Day falls on the second Monday in October.

    It took place at the Biltmore Hotel. My grandmother, my mother, and I were having lunch after a morning spent shopping. I gladly ordered a Salisbury steak. When brought to the table, it was accompanied by a plate of peas. I do not like peas now. I did not like peas then. I have always hated peas.

    “Eat your peas,” my grandmother said.

    “Mother,” said my mother in her warning voice. “He doesn't like peas. Leave him alone.”

    My grandmother did not reply, but leaned in my direction, looked me in the eye, and spoke out the fateful words that changed my life, “I'll pay you five dollars if you eat those peas.”

    I only knew that five dollars was a huge, nearly unimaginable amount of money, and awful as peas were, only one plate of them stood between me and the possession of that five dollars. I began to force them down my throat.

    My mother looked livid (铁青色的). My grandmother had a self-satisfied look and said, “I can do what I want, Ellen, and you can't stop me.” My mother glared at her mother. She glared at me. No one can glare like my mother. If there were a glaring Olympics, she would undoubtedly win the gold medal.

    I, of course, kept shoving peas down my throat, and every single pea made me want to throw up, but the magical image of the five dollars floated before me, and I finally swallowed every last one of them. My grandmother handed me the five dollars with satisfaction. My mother continued to glare in silence.

    That night, at dinner, my mother served two of my all-time favorite foods, meatloaf and mashed potatoes. Along with them came a big, steaming bowl of peas. She offered me some peas, and of course I declined. My mother fixed me with a cold eye as she heaped（堆积) a huge pile of peas onto my plate. Then came the words that were to haunt (萦绕) me for years. “You ate them for money,” she said, “You can eat them for love.”

    Generally speaking, government regulations normally ban anything from smoking in public places to parking in certain zones. But officials in the Brazilian town of Biritiba Mirim, 70km (45miles) east of Sao Paulo, have gone far beyond that. They plan to prohibit residents from dying early because the local cemetery(墓地) has reached full capacity.

    There's no more room to bury the dead, they can't be cremated(火化) and laws forbid a new cemetery. So the mayor has proposed a strange solution: outlaw death. Mayor Roberto Pereira says the bill is meant as a protest against federal regulations that prohibit new or expanded cemeteries in preservation areas. "They have not taken local demands into consideration", he claims.

    A 2003 decree(法令) by Brazil's National Environment Council forbids burial grounds in protected areas. Mr. Pereira wants to build a new cemetery, but the project has been stopped because 98% of Biritiba Mirim is considered as a preservation area.

    Biritiba Mirim, a town of 28,000 inhabitants, not only wants to prohibit residents from passing away. The bill also calls on people to take care of their health in order to avoid death. "I haven't got a job, nor am I healthy. And now they say I can't die. That's ridiculous," Amarido do Prado, an unemployed resident said.

    The city council is expected to vote on the regulation next week. "Of course the bill is laughable, illegal, and will never be approved," said Gilson Soares de Campos, an assistant of the mayor. "But can you think of a better resolution to persuade the government to change the environmental decree that is prohibiting us from building a new cemetery?" The bill states that "offenders will be held responsible for their acts." However, it does not say what the punishment will be.

    Although English is not as old as Chinese, it is spoken by many people around the world every day. English speakers are always creating (创造) new words, and we are often able to know where most words come from.

    Sometimes no one may really know where a word comes from. Did you ever think about why hamburgers are called hamburgers, especially when they are not made with ham? About a hundred years ago, some men went to America from Europe. They came from a big city in Germany called Hamburg. They didn't speak good English, but they ate good food. When some Americans saw them eating a round piece of beef, they asked the Germans what is was. The Germans didn't understand the question and answered, “We come from Hamburg.” One of these Americans owned a restaurant. He had an idea. He cooked some round pieces of bread and started selling them. Such bread came to be called “hamburgers”. Today, “hamburgers” are sold in many countries around the world.

    Whether this story is true or not, it certainly is interesting. Knowing why any word has a certain meaning is interesting, too. This reason, for most English words, can be found in any large English dictionary.

The Stanford marshmallow (棉花糖) test was originally conducted by psychologist Walter Mischel in the late 1960s. Children aged four to six at a nursery school were placed in a room. A single sugary treat, selected by the child, was placed on a table. Each child was told if they waited for 15 minutes before eating the treat, they would be given a second treat. Then they were left alone in the room. Follow-up studies with the children later in life showed a connect ion between an ability to wait long enough to obtain a second treat and various forms of success.

As adults, we face a version(版本) of the marshmallow test every day. We're not tempted (诱惑) by sugary treats, but by our computers, phones, and tablets — all the devices that connect us to the global delivery system for various types of information that do to us what marshmallows do to preschoolers.

We are tempted by sugary treats because our ancestors lived in a calorie-poor world, and our brains developed a response mechanism(机制) to these treats that reflected their value — a feeling of reward and satisfaction. But as we've reshaped the world around us, dramatically reducing the cost and effort involved in obtaining (获取) calories, we still have the same brains we had thousands of years ago, and this mismatch(不匹配) is at the heart of why so many of us struggle to resist (抵抗) tempting foods that we know we shouldn't eat.

A similar process is at work in our response to information. Our formative (有重大影响的) environment as a species was information-poor, so our brains developed a mechanism that prized (高度重视) new information. But global connectivity has greatly changed our information environment. We are now endlessly bombarded (轰炸) with new information. Therefore, just as we need to be more thoughtful (深思熟虑的) about our caloric consumption (热量消耗), we also need to be more thoughtful about our information consumption, resisting the temptation of the mental "junk food" in order to manage our time most effectively.
