Even while in a deep sleep, people can still learn brand new information. Sleepers soak in new associations between smells and sounds, knowledge that lingers(逗留) into the next waking day, researchers report online August 26 in Nature Neuroscience.
The new study is the first to show that entirely new information can get into the sleeping mind, says Anat Arzi of the Weizmann Institute of Science in Israel. “The brain is not passive while you sleep. It’s quite active. You can do quite a lot of things while you are asleep.”
But the results don’t mean that Spanish vocabulary tapes now have a place on the nightstand. Researchers have tried but largely failed to find evidence that complicated information, such as new pairs of words, can make its way into the brain during sleep.
Instead of trying to teach people something complicated like a new language, Arzi and her colleagues relied on the sense of smell and hearing. As anyone who has walked by a dumpster(垃圾车) in July knows, smells can elicit a nose-jerk reaction. Catching a bad smell automatically makes people inhale(吸气)less, reducing the size of the inhale. But a scent of fresh bread causes a long, deep inhale. Arzi and her team took advantage of this reaction for their experiment.
As people slept in the laboratory, the researchers delivered pleasant scent, such as shampoo. As this nice smell got into the sleepers’ noses, the researchers played a particular music. Later, a disgusting smell, such as rotten fish or carrion(腐肉), was paired with a different music. Neither the smell nor the sound woke people up. After just four exposures to the smell-music pair during a single night, the sleepers started to automatically respond to the tones without the accompanying smells, taking in bigger breaths when the shampoo-associated tone played and smaller breaths when played the sound linked to the rotten fish smell.
This new learned association lingered into the next waking day, too. Even though the sleepers had no idea they had been exposed to smells or sounds, their behavior proved that their brain had actually learned something during sleep. As before, the shampoo sound stimulated a long, deep inhale, while the rotten fish tone caused more shallow breaths.

查看习题详情和答案>>If you ask people to name the one person who had the greatest effect on the English language,you will get answers like “Shakespeare”,“Samuel Johnson”and“Webster”,but none of these men had any effect at all compared to a man who didn't even speak English—William the Conqueror.
Before 1066,in the land we now call Great Britain lived peoples belonging to two major language groups.In the west?central region lived the Welsh,who spoke a Celtic language,and in the north lived the Scots,whose language,though not the same as Welsh, was also Celtic.In the rest of the country lived the Saxons,actually a mixture of Anglos,Saxons,and other Germanic and Nordic peoples,who spoke what we now call Anglo?Saxon(or Old English),a Germanic language.If this state of affairs had lasted,English today would be close to German.
But this state of affairs did not last.In 1066 the Normans led by William defeated the Saxons and began their rule over England.For about a century,French became the official language of England while Old English became the language of peasants. As a result,English words of politics and the law come from French rather than German.In some cases,modern English even shows a distinction (区别) between upper class French and lower?class Anglo?Saxon in its words. We even have different words for some foods,meat in particular,depending on whether it is still out in the fields or at home ready to be cooked,which shows the fact that the Saxon peasants were doing the farming,while the upper?class Normans were doing most of the eating.
When Americans visit Europe for the first time,they usually find Germany more“foreign” than France because the German they see on signs and advertisements seems much more different from English than French does. Few realize that the English language is actually Germanic in its beginning and that the French influences are all the result of one man's ambition.
1.The two major languages spoken in what is now called Great Britain before 1066 were_________.

2.Which of the following groups of words are,by inference,rooted in French?
A.president,lawyer,beef B.president,bread,water
C.bread,field,sheep D.folk,field,cow
3.Why does France appear less foreign than Germany to Americans on their first visit to Europe?
A.Most advertisements in France appear in English.

查看习题详情和答案>>A German taxi-driver, Franz Bussman, recently found his brother who was thought to have been killed twenty years before.
While on a walking tour with his wife, he stopped to talk to a workman. After they had gone on, Mrs Bussman said that the workman was closely like her husband and even suggested that he might be his brother. Franz laughed at the idea, pointing out that his brother had been killed in action during the war. Though Mrs Bussman knew this story quite well, she thought that there was a chance in a million that she might be right.
A few days later, she sent a boy to the wokman to ask him if his name was Hans Bussman. Needless to say, the man’s name was Hans Bussman. And he really was Franz’s long-lost brother. When the brothers were reunited, Hans explained how it was that he was still alive.
After having been wounded towards the end of the war, he had been sent to hospital and was separated from his unit. The hospital had been bombed and Hans had made his way back into Western Germany on foot. Meanwhile, his unit was lost and all records of him had been destroyed.

查看习题详情和答案>>A lot of management training each year for Circle K Corporation, a national chain of convenience stores. Among the topics we address in our course is the retention(保护力) of quality employees-a real challenge to managers when you consider the pay scale(标准)in the service industry. During these discussions, I ask the participants(参加者), “What has caused you to stay long enough to become a manager?” Some time back a new manager took the question and slowly, with her voice almost breaking, said, “It was a $19 baseball glove.”
Cynthia told the group that she originally took a Circle K clerk job as an interim(临时的) position while she looked for something better. On her second or third day behind the counter, she received a phone call from her nine-year-old son, Jessie. He needed a baseball glove for Little League. She explained that as a single mother, money was very tight, and her first check would have to go for paying bills. Perhaps she could buy his baseball glove with her second or third check. When Cynthia arrived for work the next morning, Patricia, the store manager, asked her to come to the small room in the back of the store that served as an office. Cynthia wondered if she had done something wrong or left some part of her job incomplete from the day before. She was concerned and confused.
Patricia handed her a box. “I overheard you talking to your son yesterday,” she said, “and I know that it is hard to explain things to kids. This is a baseball glove for Jessie because he may not understand how important he is, even though you have to pay bills before you can buy gloves. You know we can’t pay good people like you as much as we would like to; but we do care, and I want you to know you are important to us.”
The thoughtfulness, empathy and love of this convenience store manager demonstrates vividly that people remember more how much an employer cares than how much the employer pays. An important lesson for the price of a Little League baseball glove.
