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.

    One day, I received a call from a colleague. He was about to give a student a zero for his answer to a physical problem， while the student claimed a perfect score. I was elected as their arbiter. I read the examination problem: “Show how it is possible to determine the height of a tall building with the aid of a barometer(气压计).” The student had answered: “Take the barometer to the top of the building，attach a long rope to it，lower it to the street， and then bring it up, measuring the length of the rope. The length of it is the height of the building. ”

    The student had really answered the question completely, but the answer didn't confirm his competence in physics. I suggested the student try again. I gave him six minutes to answer the question, warning that the answer should show some knowledge of physics. Five minutes later, he said he had many answers and clashed off one, which read： “Take the barometer to the top of the building and lean over the edge of the roof. Drop the barometer, timing its fall with a stopwatch. Then, use the physical formula (公式）to calculate the height of the building. ”

    At this point, my colleague had to accept it, and then the student made almost full marks. I couldn't help asking the student what the other answers were. He listed many others ，and then added “Probably the best is to take the barometer to the administrator and said to him，' Sir, here is a fine barometer. If you tell me the height of the building, I will give it to you.，”

    Then, I asked the student if he really did not know the conventional answer to this question. He admitted that he did, but said that he was fed up with high school and college instructors trying to teach him how to think.

    The name of the student was Bohr who later was famous all over the world. He won the Nobel Prize for Physics in 1922.

    Grown-ups are often surprised by how well they remember something they learned as children but have never practiced ever since. A man who has not had a chance to go swimming for years can still swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the words for years can teach her daughter the poem that begins “Twinkle, twinkle, little star” or remember the story of Cinderella or Goldilocks and the Three Bears.

    One explanation is the law of overlearning, which can be stated as follows: Once we have learned something, additional learning experiences increase the length of time we will remember it.

    In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as “Twinkle, twinkle, little star” and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn.

    The multiplication tables (乘法口诀表) are an exception to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood.

    The law of overlearning explains why cramming (突击学习) for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one's future development.

    Does your older brother think he's cleverer than you? Well, he's probably right. According to a new research published in the journal Intelligence, the oldest children in families are likely to have the highest IQs and the youngest the lowest.

    A number of studies have suggested that IQ scores decline with birth order. In the most recent study, at Vrije University, Amsterdam, researchers looked at men and women whose IQ had been tested at the ages of 5, 12, and 18.

    The results, which show a trend for the oldest to score better than the youngest in each test, involved about 200,000 people. That showed that first-borns had a three-point IQ advantage over the second-born, who was a point ahead of the next in line.

    The order of birth can also affect personality, achievement, and career, with first-borns being more academically successful and more likely to win Nobel prizes. However, eldest children are less likely to be radical(不同凡响的) and pioneering. Charles Darwin, for example, was the fifth child of six.

    Exactly why there should be such differences is not clear, and there are a number of theories on environmental influences on the child.

    The so-called dilution(稀释法) theory suggests that as family resources, both emotional and physical, as well as economic, are limited, it follows that, as a result , as more children come along, the levels of parental attention and encouragement will drop. Another theory is that the intellectual environment in the family favors the first-born who has, at least for some time, the benefit of individual care and help.

    The theory which enjoys the most support is that the extra time and patience that the earlier-borned get from their parents, compared with those arriving later, gives them an advantage.

Europe is famous for big cities and world-class art museums. It's easy not to notice the small, beautiful villages in Europe. However, if you're after relaxation, peaceful country walks, beautiful buildings, and chances for different cultures on your next trip, consider cutting down some of your city time and head out to a village instead. Here are three of the most beautiful villages in Europe, along with our top picks for places to stay in each.

Bibury in Gloucestershire, England

Often praised as the most beautiful village of the Cotsworlds, Bibury is also one of the most popular places for visitors to stay in the area, and attracts a lot of tourists from around the world. It's set among the green hills that the area is known for and is composed of light-beige(浅米色) stone houses, including the famous Arlington Row, a line of houses dating back to 1380.

Cong in County Mayo, Ireland

Set on a small sea-facing island on the western coast of Ireland, Cong is a quiet village that's famous for its grey stone ruins and many outdoor activities. One of the biggest reasons for its fame is that the 1952 film The Quiet Man was made there, but the biggest draw for most visitors is the chance to visit (or stay in) Ashford Castle, which is now run as a great expensive hotel.

Montepulciano in Tuscany, Italy

Spread over a hilltop nearly 2, 000 meters above sea level, the Tuscan village of Montepulciano offers beautiful buildings from the Middle Ages, as well as many chances to visit wineries(酿酒厂) and taste the locally produced Vino Nobel di Montepulciano. With fortifications(防御工事) dating back to the 14th century, the village has churches and public squares, which are truly fascinating.
