A study published in Child Development,the top－ranked educational psychology journal,provides some of the strongest evidence yet that gesturing may have a unique effect on learning.Teachers in the United States tend to use gestures less than teachers in other countries.

     "Gesturing can be a very beneficial tool that is completely free and easily employed in classrooms," said Kimberly Fenn,study co－author and assistant professor of psychology at Michigan State University."And I think it can have long－lasting effects."

    Fenn and Ryan Duffy of MSU and Susan Cook of the University of Iowa conducted an experiment with 184 second－,third－ and fourth－graders in Michigan elementary classrooms.

    Half of the students were shown videos of an instructor teaching math problems using only speech.The others were shown videos of the instructor teaching the same problems using both speech and gestures.In the speech－only videos,the instructor simply explains the problem.In the other videos,the instructor uses two hand gestures while speaking,using different hands to refer to the two sides of the equation.Students who learned from the gesture videos performed better on a test given immediately afterward than those who learned from the speech－only video.

    Another test was given 24 hours later,and the gesture students actually showed improvement in their performance while the speech－only students did not.

    While previous research has shown the benefits of gestures in a one－on－one tutoring－style environment,the new study is the first to test the role of gestures in equivalence learning in a regular classroom.

    The study also is the first to show that gestures can help students transfer learning to new contexts—such as transferring the knowledge learned in an addition－based equation to a multiplication－based equation.

    Fenn noted that U.S.students lag behind those in many other Western countries in math and have a particularly hard time mastering equivalence problems in early grades."So if we can help them grasp this foundational knowledge earlier," she said,"it will help them as they learn algebra and higher levels of mathematics."

    New Year's resolutions(决心)have been around long enough that we all scent to stick to the same ones--hit the gym, lay off the candy, read more books, call your mother-regardless of whether we follow through with our intentions.

    While January 1st seems like the perfect time to have a new start again, exactly when people developed that mindset(思维模式)isn't common knowledge. It turns out that the modern belief of' a New Year's resolution isn't as old as you thought. According to many historians, the ancient Babylonians were the first group of people to make New Year's resolutions. However, instead of making a commitment to self improvement, they made a commitment to the gods to pay their debts and return any objects they had borrowed.

    An ancient Roman tradition from 46 B. C, bears even more likeness to modern resolutions. Emperor Julius Caesar declared January the month of Janus. Romans believed Janus looked backwards into the previous year and ahead into the future. In his honor, they made sacrifices to the god and promises of good behavior for the coining year.

    But the modern New Year's resolution didn't fully form until centuries later. The practice was common enough by the early 1800s. An article in 1802 states, "Statesmen have sworn to have no other objet in view than the good of their country. the physicians have determined to advise the use of medicine no more than is necessary, and to the very reasonable in their fees.”

    The first time “New Year's resolution" appeared as a phrase was in the January 1st issue of a Boston newspaper in 1813. “I believe there are a lot of people," the article goes, “with a serious determination of beginning the New Year with new resolutions and new behavior, and with the full belief that they shall accept punishment for all their former faults and wipe them away.

    So as you make (and possibly fail at) your New year's resolutions, know that you're in good company.

    Meeting people from another culture can be difficult. From the beginning, people may send the wrong signal. Or they may pay no attention to signals from another person who is trying to develop a relationship.

    Different cultures emphasize (强调) the importance of relationship building to a greater or lesser degree. For example, business in some countries is not possible until there is a relationship of trust. Even with people at work, it is necessary to spend a lot of time in "small talk", usually over a glass of tea, before they do any job. In many European countries -- like the UK or France -- people find it easier to build up a lasting working relationship at restaurants or cafes rather than at the office.

    Talk and silence may also be different in some cultures. I once made a speech in Thailand. I had expected my speech to be a success and start a lively discussion; instead there was an uncomfortable silence. The people present just stared at me and smiled. After getting to know their ways better, I realized that they thought I was talking too much. In my own culture, we express meaning mainly through words, but people there sometimes feel too many words are unnecessary.

    Even within Northern Europe, cultural differences can cause serious problems. Certainly, English and German cultures share similar values; however, Germans prefer to get down to business more quickly. We think that they are rude. In fact, this is just because one culture starts discussions and makes decisions more quickly.

    People from different parts of the world have different values, and sometimes these values are quite against each other. However, if we can understand them better, a multicultural environment will offer a wonderful chance for us to learn from each other.

When I lived in Spain, some Spanish friends of mine decided to visit England by car. Before they left, they asked me for advice about how to find accommodation. I suggested that they should stay at "bed and breakfast" houses, because this kind of accommodation gives a foreign visitor a good chance to speak English with the family. My friends listened to my advice, but they came back with some funny stories.

"We didn't stay at bed and breakfast houses," they said, "because we found that most families were on holiday." I thought this was strange. Finally I understood what had happened. My friends spoke little English, and they thought "VACANCIES" meant "holidays", because the Spanish word for "holidays" is said "vacaciones". So they did not go to the house where the sign outside said "VACANCIES", which in English means there are free rooms. Then my friends went to the houses where the sign said "NO VACANCIES", because they thought this meant people who owned the house were not away on holiday. But they found that these houses were all full. As a result, they stayed at hotels.

We laughed about this and about mistakes my friends made in reading other signs. In Spanish, the word "DIVERSION" means "fun". In English, it means that workmen are repairing the road, and that you must take a different road. When my friends saw the word "DIVERSION" on a road sign, they thought they were going to have fun. Instead, the road ended in a large hole.

English people have problems too when they learn foreign languages. Once in Paris when someone offered me some more coffee, I said "Thank you" in French, I meant that I would like some more, however to my surprise the coffee pot was taken away! Later I found out that "Thank you" in French means "No, Thank you".

    Standing in line for the latest iPhone at the Apple store  queuing for tickets to the match or even just waiting at the post office might just have got a lot easier.

Japanese car-maker Nissan announces that it has just the thing to relieve the painful legs of tired queuers.

    The new system of self-driving chairs is designed to detect when someone at the front of the queue is called, and automatically move everyone else one step forward in line.

    The new invention is shown in a company video, which shows a busy restaurant with customers waiting outside. In the video, diners are sitting in a row of chairs, but will not have to stand when the next hungry diner is called to a table. Instead, the chairs, equipped with autonomous technology that detects the seat ahead, move along a path toward the front of the line. When the person at the front of the queue is called, the empty chair at the front can sense it is empty and so moves out of line. Cameras on the remaining chairs then sense the movement and follow automatically.

    “The system, which is similar to the kind used in Nissan's autonomous vehicle technology, will be tested at select restaurants in Japan this year," Nissan said. "It appeals to anyone who has queued for hours outside a crowded restaurant: it rids the boredom and physical pain of standing in line,” Nissan added.

    Although Tokyo has some 160,000 restaurants, long queues are not uncommon. Chosen restaurants that meet the criteria will be able to show the chairs outside their restaurants next year. Nissan also released a short video showing the chairs being used in an art gallery, moving slowly in front of the various paintings to let viewers appreciate the art without the need to stand up.
