You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passagethrough carefully before making your choices. Each choice in the bank is identified by a letter.Please mark the corresponding letter for each item on Answer Sheet 2 with a single linethrough the centre. You may not use any of the words in the bank more than once. Questions 26 to 35 are based on the following passage.Let’s all stop judging people who talk to themselves. New research says that those who can’t seem to keep their inner monologues( 独白) in are actually more likely to stay on task, remain 26 better and show improved perception capabilities. Not bad, really, for some extra muttering.According to a series of experiments published in the Quarterly Journal of Experimental Psychology by professors Gary Lupyan and Daniel Swignley, the act of using verbal clues to 27 mental pictures helps people function quicker.In one experiment, they showed pictures of various objects to twenty 28 and asked them to find just one of those, a banana. Half were 29 to repeat out loud what they were looking for and the other half kept their lips 30 . Those who talked to themselves found the banana slightly faster than those whodidn’t,the researchers say. In other experiments, Lupyan and Swignley found that 31 the name of acommon product when on the hunt for it helped quicken someone’s pace, but talking about uncommon items showed no advantage and slowed you down.Common research has long held that talking themselves through a task helps children learn, although doing so when you’ve 32 matured is not a great sign of 33 . The two professors hope to refute that idea, 34 that just as when kids walk themselves through a process, adults can benefit from using language not just to communic ate, but also to help “augment thinking”.Of course, you are still encouraged to keep the talking at library tones and, whatever you do, keep the information you share simple, like a grocery list. At any 35 , there’s still such a thing as too much information.Section BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph fromwhich the information is derived. You may choose a paragraph more than once.Eachparagraph is marked with a letter. Answer the questions by marking the correspondingletter on Answer Sheet 2.Rich Children and Poor Ones Are Raised Very Differently[A]The lives of children from rich and poor American families look more different than ever before.[B]Well-off families are ruled by calendars, with children enrolled in ballet, soccer and after-school programs, according to a new Pew Research Center survey. There are usually two parents, who spend a lotof time reading to children and worrying about their anxiety levels and hectic schedules.[C]In poor families, meanwhile, children tend to spend their time at home or with extended family. They are more likely to grow up in neighborhoods that their parents say aren’t great for raising children, and their parents worry about them getting shot, beaten up or in trouble with the law.[D]The class differences in child rearing are growing — a symptom of widening inequality withfar-reaching consequences. Different upbringings set children on different paths and can deepen socioeconomic divisions, especially because education is strongly linked to earnings. Children grow uplearning the skills to succeed in their socioeconomic stratum (阶层), but not necessarily others.[E]“Early childhood experiences can be very consequential for children’s long-term social, emotional and cognitive development,” said Sean Reardon, professor of poverty and inequality in education at Stanford Universi ty. “And because those influence educational success and later earnings, early childhood experiences cast a lifelong shadow.” The cycle continues: Poorer parents have less time and fewer resources to invest in their children, which can leave children less prepared for school and work, which leads to lower earnings.[F]American parents want similar things for their children, the Pew report and past research have found: for them to be healthy and happy, honest and ethical, caring and compassionate. There is no best parenting style or philosophy, researchers say, and across income groups, 92% of parents say they are doing a good job at raising their children. Yet they are doing it quite differently. Middle-class and higher- income parents see their children as projects in need of careful cultivation, says Annette Lareau, whose groundbreaking research on the topic was published in her book Unequal Childhoods: Class, Race and Family Life. They try to develop their skills through close supervision and organized activities, and teach children to question authority figures and navigate elite i nstitutions.[G]Working-class parents, meanwhile, believe their children will naturally thrive, and give them far greater independence and time for free play. They are taught to be compliant and respectful to adults. There are benefits to both approaches. Working-class children are happier, more independent, complain less and are closer with family members, Ms. Lareau found. Higher-income children are more likely to declare boredom and expect their parents to solve their problems. Yet later on, the more affluent children end up in college and on the way to the middle class, while working-class children tend to struggle. Children from higher-income families are likely to have the skills to navigate bureaucracies and succeed in schools and workplaces, Ms. Lareau said.[H]“Do all parents want the most success for their children? Absolutely,” she said. “Do some strategies give children more advantages than others in institutions? Probably they do. Will parents be damaging children if they have one fewer organized activity? No, I really doubt i t.”[I]Social scientists say the differences arise in part because low-income parents have less money to spend on music class or preschool, and less flexible schedules to take children to museums or attend school events. Extracurricular activities reflect the differences in child rearing in the Pew survey, which was of a nationally representative sample of 1,807 parents. Of families earning more than $75,000 a year, 84% say their children have participated in organized sports over the past year, 64% have done volunteer work and 62% have taken lessons in music, dance or art. Of families earning less than $30,000, 59% of children have done sports, 37% have volunteered and 41% have taken arts classes.[J]Especially in affluent families, children start young. Nearly half of high-earning, college-graduate parents enrolled their children in arts classes before they were 5, compared with one-fifth of low-income, less- educated parents. Nonetheless, 20% of well-off parents say their children’s schedules are too hectic, compared with 8% of poorer parents.[K]Another example is reading aloud, which studies have shown gives children bigger vocabularies and better reading comprehension in school. 71% of parents with a college degree say they do it every day, compared with 33% of those with a high school diploma or less. White parents are more likely than others to read to their children daily, as are married parents. Most affluent parents enroll their children in preschool or day care, while low-income parents are more likely to depend on family members. Discipline techniques vary by education level: 8% of those with a postgraduate degree say they often beat their children, compared with 22% of those with a high school degree or less.[L]The survey also probed attitudes and anxieties. Interestingly, parents’ attitudes toward education do not seem to reflect their own educational background as much as a belief in the importance of education for upward mobility. Most American parents say they are not concerned about their children’s grades as long as they work hard. But 50% of poor parents say it is extremely important to them that their children earn a college degree, compared with 39% of wealthier parents.[M]Less-educated parents, and poorer and black and Latino parents are more likely to believe that there is no such thing as too much involvement in a child’s education. Parents who are white, wealthy or college- educated say too much involvement can be bad. Parental anxieties reflect their circumstances. High- earning parents are much more likely to say they live in a good neighborhood for raising children. While bullying is parents’ greatest concern over all, nearly half of low-income parents worry their child will get shot, compared with one-fifth of high-income parents. They are more worried about their children being depressed or anxious.[N]In the Pew survey, middle-class families earning between $30,000 and $75,000 a year fell right between working-class and high-earning parents on issues like the quality of their neighborhood for raising children, participation in extracurricular activities and involvement in their children’ s education.[O]Children were not always raised so differently. The achievement gap between children from high- and low-income families is 30-40% larger among children born in 2001 than those born 25 years earlier, according to Mr. Reardon’ s research. People used to live near people of different income levels; neighborhoods are now more segregated by income. More than a quarter of children live in single-parent households — a historic high, according to Pew 一and these children are three times as likely to live in poverty as those who live with married parents. Meanwhile, growing income inequality has coincided with the increasing importance of a college degree for earning a middle-class w age.[P]Yet there are recent signs that the gap could be starting to shrink. In the past decade, even as income inequality has grown, some of the socioeconomic differences in parenting, like reading to children and going to libraries, have narrowed.[Q]Public policies aimed at young children have helped, including public preschool programs and reading initiatives. Addressing differences in the earliest years, it seems, could reduce inequality in the next generation.36.Working-class parents teach their children to be obedient and show respect to adults.37.American parents, whether rich or poor, have similar expectations of their children despite different ways of parenting.38.While rich parents are more concerned with their children’s psychological well-being, poor parents are more worried about their children’s safety.39.The increasing differences in child rearing between rich and poor families reflect growing social inequality.40.Parenting approaches of working-class and affluent families both have a dvantages.41.Higher-income families and working-class families now tend to live in different neighborhoods.42.Physical punishment is used much less by well-educated parents.43.Ms. Lareau doesn’t believe participating in fewer after-class activities will negatively affect children’s development.44.Wealthy parents are concerned about their children’s mental health and busy schedules.45.Some socioeconomic differences in child rearing have shrunk in the p ast ten years.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Youshould decide on the best choice and mark the corresponding letter on Answer Sheet 2 with asingle line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Tennessee’s technical and community colleges will not outsource(外包) management of their facilities to a private company, a decision one leader said was bolstered by an analysis of spending at each campus.In an email sent Monday to college presidents in the Tennessee Board of Regents system, outgoing Chancellor John Morgan said an internal analysis showed that each campus’ spending on facilities management fell well below the industry standards identified by the state. Morgan said those findings —which included data from the system’s 13 community colleges, 27 technical colleges and six universities —were part of the decision not to move forward with Governor Bill Haslam’s proposal to privatize management of state buildings in an effort to save money.“While these numbers are still being validated by the state, we feel any adjustments they might suggest will be immaterial,” Morgan wrote to the presidents. “System institutions are operating very efficiently based on this analysis, raising the question of the value of pursuing a broad scale outsourcing initiative.”Worker’s advocates have criticized Haslam’s plan, saying it would mean some campus workers would lose their jobs or benefits. Haslam has said colleges would be free to opt in or out of the out souring plan, which has not been finalized.Morgan notified the Haslam administration of his decision to opt out in a letter sent last week. That letter, which includes several concerns Morgan has with the plan, was originally obtained by The Commercial Appeal in Memphis.In an email statement from the state’s Office of Customer Focused Government, which is examining the possibility of outsourcing, spokeswoman Michelle R. Martin said officials were still working to analyze the data from the Board of Regents. Data on management expenses at the college system and in other state departments will be part of a “business justification” the state will use as officials deliberate the specifics of an outsourcing plan.“The state’s facilities management project team is still in the process of developing its business justification and expects to have that completed and available to the public at the end of February,” Martin said. “At this time there is nothing to take action on since the analysis has yet to be completed.”Morgan’s comments on outsourcing mark the second time this month that he has come out against one of Haslam’s plans for higher education in Tennessee. Morgan said last week that he would retire at the end of January because of the governor’s proposal to split off six universities of the Board of Regents system and create separate governing boards for each of them. In his resignation letter, Morgan called the reorganization “unworkable”.46.What do we learn about the decision of technical and community colleges in Tennessee?A)It is backed by a campus spending analysis.B)It has been flatly rejected by the governor.C)It has neglected their faculty’s demands.D )It will improve their financial situation.47.What does the campus spending analysis reveal?A)Private companies play a big role in campus management.B)Facilities management by colleges is more c ost-effective.C)Facilities management has greatly improved in recent years.D)Colleges exercise foil control over their own financial a ffairs.48.Workers’ supporters argue that Bill Haslam’s proposal would .A)deprive colleges of the right to manage their facilitiesB)make workers less motivated in performing dutiesC)render a number of campus workers joblessD)lead to the privatization of campus facilities49.What do we learn from the state spokeswoman’s response to John Morgan’s d ecision?A)The outsourcing plan is not yet finalized.B)The outsourcing plan will be implemented.C)The state officials are confident about the outsourcing plan.D)The college spending analysis justifies the outsourcing plan.50.Why did John Morgan decide to resign?A)He had lost confidence in the Tennessee state government.B)He disagreed with the governor on higher education policies.C)He thought the state’s outsourcing proposal was simply unworkable.D)He opposed the governor’s plan to reconstruct the college board system.Passage TwoQuestions 51 to 55 are based on the following passage.Beginning in the late sixteenth century, it became fashionable for young aristocrats to visit Paris,Venice, Florence, and above all, Rome, as the culmination(终极) of their classical education. Thus wasborn the idea of the Grand Tour, a practice which introduced Englishmen, Germans, Scandinavians, and also Americans to the art and culture of France and Italy for the next 300 years. Travel was arduous and costly throughout the period, possible only for a privileged class—the same that produced gentlemen scientists, authors, antique experts, and patrons of the arts.The Grand Tourist was typically a young man with a thorough grounding in Greek and Latin literature as well as some leisure time, some means, and some interest in art. The German traveler Johann Winckelmann pioneered the field of art history with his comprehensive study of Greek and Roman sculpture; he was portrayed by his friend Anton Raphael Mengs at the beginning of his long residence in Rome. Most Grand Tourists, however, stayed for briefer periods and set out with less scholarly intentions, accompanied by a teacher or guardian, and expected to return home with souvenirs of their travels as well as an understanding of art and architecture formed by exposure to great masterpieces.London was a frequent starting point for Grand Tourists, and Paris a compulsory destination; many traveled to the Netherlands, some to Switzerland and Germany, and a very few adventurers to Spain, Greece, or Turkey. The essential place to visit, however, was Italy. The British traveler Charles Thompsonspoke for many Grand Tourists when in 1744 he described himself as “being impatiently desirous of viewing a country so famous in history, a country which once gave laws to the world, and which is at present the greatest school of music and painting, contains the noblest productions of sculpture and architecture, and is filled with cabinets of rarities, and collections of all kinds of historical relics”. Within Italy, the great focus was Rome, whose ancient ruins and more recent achievements were shown to every Grand Tourist. Panini’s Ancient Rome a nd Modem Rome represent the sights most prized, including celebrated Greco-Roman statues and views of famous ruins, fountains, and churches. Since there were few museums anywhere in Europe before the close of the eighteenth century, Grand Tourists often saw paintings and sculptures by gaining admission to private collections, and many were eager to acquire examples of Greco-Roman and Italian art for their own collections. In England, where architecture was increasingly seen as an aristocratic pursuit, noblemen often applied what they learned from the villas of Palladio in the Veneto and the evocative ( 唤起回忆的) ruins of Rome to their own country houses and gardens.51.What is said about the Grand Tour?A)It was fashionable among young people of the time.B)It was unaffordable for ordinary people.C)It produced some famous European artists.D)It made a compulsory part of college education.52.What did Grand Tourists have in common?A)They had much geographic knowledge.B)They were courageous and venturesome.C)They were versed in literature and interested in art.D)They had enough travel and outdoor-life experience.53.How did Grand Tourists benefit from their travel?A)They found inspiration in the world’s greatest masterpieces.B)They got a better understanding of early human civilization.C)They developed an interest in the origin of modem art forms.D)They gained some knowledge of classical art and architecture.54.Why did many Grand Tourists visit the private collections?A)They could buy unique souvenirs there to take back home.B)Europe hardly had any museums before the 19th century.C)They found the antiques there more valuable.D)Private collections were of greater variety.55.How did the Grand Tour influence the architecture in England?A)There appeared more and more Roman-style buildings.B)Many aristocrats began to move into Roman-style villas.C)Aristocrats,country houses all had Roman-style gardens.D) Italian architects were hired to design houses and gardens.Part IV Translation (30 minutes) Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese intoEnglish.

考研英语(阅读)-试卷7(总分60,考试时间90分钟)2. Reading ComprehensionSection II Reading ComprehensionPart ADirections: Read the following four texts. Answer the questions below each text by choosing A, B, C or D.John Stuart Mill argued in the 19th century that an individual should be free to do as he pleased, so long as he did not harm anyone else. The ban on smoking in pubs, bars **pany cars—in effect, in all enclosed public spaces—that came into effect in England in 2007 was informed by such thinking. Brought in to protect the health of non-smokers who worked in or frequented such places, it seems to have worked. Research published on June 9th this year shows that, since the ban, fewer people have been admitted to hospital with symptoms of a heart attack. Second-hand smoke from a burning cigarette is far more noxious than the nicotine-infused fumes inhaled by the smoker. In the minutes after a neighbor has lit a cigarette, a passive smoker"s chances of suffering an immediate heart attack rise rapidly as toxins in the fug make his blood stickier. His long-term risk also rises, as narrowing arteries threaten him with heart disease and his chances of developing lung cancer and numerous other nasties also increase. Anna Gilmore of the University of Bath and her colleagues looked at how many people were admitted to hospital with a heart attack in England between 2002 and 2008. About 110,000 people are struck down each year; almost a fifth of them die before they reach hospital, and a further tenth within a month of going into one. Ms Gilmore and her team found that, in the 12 months after the smoking ban came into force, some 1,200 fewer people were admitted to hospital with heart attacks than even the prevailing downward trend had suggested was likely. That drop of 2.4% saved £8.4m in emergency hospital care. When the ban took effect, England was the largest jurisdiction to forbid smoking in enclosed public spaces. Studying a large population tends to give a more accurate result than studies of smaller places such as Scotland, parts of Italy and New York state, where more impressive reductions have been claimed. When the town of Helena, in Montana, banned smoking for six months, for example, hospital admissions for heart attacks almost halved from seven to less than four a month. Ms Gilmore reckons her figure, which covers far more people, is more robust. Because heart disease is the **mon cause of death in wealthy countries, even a relatively small reduction in heart attacks is good news for a great many people. In Britain, the freedom to smoke remains, but not at the expense of others.1. Which of the following behaviors would John Stuart Mill most probably approve?A. Indulging in candy and ice-cream.B. Snoring during a conference.C. Keeping a stray child to one"s own.D. Enjoying oneself drunk driving.2. According to Paragraph 1, the ban on smoking in EnglandA. is applicable to all public places.B. was proposed by John Stuart Mill.C. aims to protect the smokers" health.D. has achieved some good results.3. Second-hand smoke from a burning cigaretteA. consists of nicotine-infused fumes.B. won"t be inhaled by passive smokers.C. increases its inhaler"s disease risk.D. produces toxins in the inhaler"s blood.4. It"s indicated in Paragraph 3 that the smoking banA. was brought into force in 2008.B. reduces 1200 heart attacks per year.C. drops heart attacks by 2.4% in 2008.D. fulfills its purpose beyond expectation.5. Anna Gilmore regard their research as more convincing in that itA. is authorized by the largest jurisdiction.B. has a broader coverage of study subjects.C. is believed by many to be more accurate.D. is conducted in more specific places.Is athlete prowess attained or innate? Those who have suffered the scolding of a tyrannical games master at school might be forgiven for doubting the idea that anyone and everyone is capable of great sporting achievement, if only they would put enough effort into it. Practice may make perfect, but not all are built in ways that make it worth bothering in the first place. The latest evidence of this truth has been gathered by Sabrina Lee of Simon Fraser University in Vancouver and Stephen Piazza at Pennsylvania State University. They have looked at the anatomy of sprinters and found that their feet are built differently from those of couch potatoes. They looked at seven university splinters who specialize in the 100-metre dash and five 200-metre specialists, **pared them with 12 non-athletic university students of the same height. In particular, they looked at the sizes of bones of the toes and heel. They also used ultrasonic scanning to measure the sliding motion of the Achilles tendons(the tendon inside the back of your leg just above your heel)of their volunteers as their feet moved up and down. This allowed them to study the length of the lever created by the tendon as it pulls on the back of the heel to make the foot bend and push off the ground. Dr Lee and Dr Piazza found that the toes of their sprinters averaged 8.2cm in length, while those of non-sprinters averaged 7.3cm. The length of the lever of bone that the Achilles tendon pulls on also differed, being a quarter shorter in sprinters. These findings suggest sprinters get better contact with the ground by having longer toes. That makes sense, as it creates a firmer platform to push against. In a sprint race, acceleration off the block is everything. The reason for the difference in the Achilles tendons, though, is less immediately obvious. At first sight, sprinters might be expected to have more Achilles leverage than average, not less. First sight, however, is wrong. When muscles have to contract a long way, they usually do so quickly and with little force. When contracting short distances, though, they move more slowly and generate more force. Having a short Achilles lever allows the muscles that pull on the tendon to generate asmuch as 40% more force than the same muscles in a non-sprinter would be able to manage. It is possible—just—that these anatomical differences are the result of long and rigorous training., But it is unlikely. Far more probable is that the old saying of coaches, that great sprinters are born not made, is true. Everyone else, games masters included, should just get used to the idea.6. According to Paragraph 1, the idea that practice makes perfectA. is suspected by all the athletes.B. owes success to efforts rather than gifts.C. explains the brilliant skills of most athletes.D. isn"t accepted by tyrannical games masters.7. Dr Lee and Dr Piazza found that the feet of the sprinters are different from those ofA. unskilled coaches.B. clumsy athletes.C. exerciseless non-athletes.D. specialists from other fields.8. Longer toes of a sprinter are helpful in that they enable him toA. touch the ground more safely.B. contract muscles more quickly.C. have a better starting speed.D. generate more force in the feet.9. We can learn from this text that the advantages of a **e fromA. his longer toes and shorter lever of bone.B. his special feet as a result of years of practice.C. his stronger muscles and better endurance.D. his professional training and inborn gifts.10.

Excellent athletes are born rather than made.It may not be obvious, but hearing two languages regularly during pregnancy puts infants on the road to bilingualism by birth. According to new findings in Psychological Science, a journal of the Association for Psychological Science, infants born to bilingual mothers exhibit different language preferences than infants born to mothers speaking only one language. Psychological scientists Krista Byers-Heinlein and Janet F. Werker from the University of British Columbia along with Tracey Burns of the Organization for Economic Co-operation and Development in France wanted to investigate language preference and discrimination in newborns. Two groups of newborns were tested in these experiments: English monolinguals(whose mothers spoke only English during pregnancy)and Tagalog-English bilinguals(whose mothers spoke both Tagalog, a language spoken in the Philippines, and English regularly during pregnancy). The researchers employed a method known as "high-amplitude sucking-preference procedure" to study the infants" language preferences. This method capitalizes on the newborns" sucking reflex—increased sucking indicates interest in a stimulus. In the first experiment, infants heard 10 minutes of speech, with every minute alternating between English and Tagalog. Results showed that English monolingual infants were more interested in English than Tagalog—they exhibited increasedsucking behavior when they heard English than when they heard Tagalog being spoken. However, bilingual infants had an equal preference for both English and Tagalog. These results suggest that prenatal bilingual exposure may affect infants" language preferences, preparing bilingual infants to listen to and learn about both of their native languages. To learn two languages, bilingual newborns must also be able to keep their languages apart. To test if bilingual infants are able to discriminate between their two languages, infants listened to sentences being spoken in one of the languages until they lost interest. Then, they either heard sentences in the other language or heard sentences in the same language, but spoken by a different person. Infants exhibited increased sucking when they heard the other language being spoken. Their sucking did not increase if they heard additional sentences in the same language. These results suggest that bilingual infants, along with monolingual infants, are able to discriminate between the two languages, providing a mechanism from the first moments of life that helps ensure bilingual infants do not confuse their two languages. The researchers observe that, "Monolingual newborns" preference for their single native language directs listening attention to that language" and that, "Bilingual newborns" interest in both languages helps ensure attention to, and hence further learning about, each of their languages." Discrimination of the two languages helps prevent confusion. The results of these studies demonstrate that the roots of bilingualism run deeper than previously imagined, extending even to the prenatal period.11. The purpose of the experiments in Paragraph 2 is to find outA. infants" sucking reactions to language stimulus.B. language likings and discerning ability of infants.C. children"s ability to alternate between two languages.D. infants" sucking preference between different languages.12. In the "high-amplitude sucking-preference procedure", stronger language preference is shown byA. more sucking behaviors.B. greater speech attentiveness.C. more exposure to that language.D. longer sucking time.13. According to Paragraph 3, language learning of an infantA. begins before it comes into the world.B. is decided by its mother"s language preference.C. is influenced by its lingual environment before birth.D. depends on its language preference before birth.14. Which of the following is true of bilingual newborns?A. They have a preference between the two languages.B. They only notice a new language.C. They have more advantage than monolingual newborns.D. They can distinguish between the two languages.15. Bilingual newborns" interest in both languages is helpful because it enables them toA. focus on and better study both languages.B. keep the two languages apart.C. obtain longer listening attention.D. find out the roots of bilingualism.If you"re like most people, you"re way too smart for advertising. You flip right past newspaper ads and never click on ads online. That, at least, is what we tell ourselves. But what we tell ourselves is nonsense. Advertising works, which is why, even in hard economic times, Madison Avenue is a $34 billion-a-year business. And if Martin Lindstrom, author of the best seller Buyology and a marketing consultant, is correct, trying to tune this stuff out is about to get a whole lot harder. Lindstrom is a practitioner of neuro-marketing research, in which consumers are exposed to ads while hooked up to machines that monitor brain activity, pupil dilation, sweat responses and flickers in facial muscles, all of which are markers of emotion. According to his studies, 83% of all forms of advertising principally engage only one of our senses: sight. Hearing, however, can be just as powerful, though advertisers have taken only limited advantage of it. Historically, ads have relied on jingles and slogans to catch our ear, largely ignoring everyday sounds. Weave this stuff into an ad campaign, and we may be powerless to resist it. To figure out what most appeals to our ear, Lindstrom wired up his volunteers, then played them recordings of dozens of familiar sounds, from McDonald"s ubiquitous "I"m Lovin" It" jingle to birds chirping and cigarettes being lit. The sound that blew the doors off all the rest—both in terms of interest and positive feelings—was a baby giggling. The other high-ranking sounds, such as the hum of a vibrating cell phone, an ATM dispensing cash, and etc, were less primal but still powerful. In all of these cases, it didn"t take a Mad Man to invent the sounds, infuse them with meaning and then play them over and over until the subjects internalized them. Rather, the sounds already had meaning and thus triggered a cascade of reactions: hunger, thirst, happy anticipation. "Cultural messages that get into your nervous system are **mon and make you behave certain ways," says neuroscientist Read Montague of Baylor College of Medicine. Advertisers who fail to understand that pay a price. Lindstrom admits to being mystified by TV ads that give viewers close-up food-porn shots of meat on a grill but accompany that with generic jangly guitar music. One of his earlier brain studies showed that numerous regions, jump into action when such discordance occurs, trying to make sense of it. TV advertisers aren"t the only ones who may start putting sound to greater use, retailers are also catching on. Lindstrom is consulting with clients about employinga similar strategy in European supermarkets.16. According to Paragraph 1, advertisingA. is mainly seen in newspapers or online.B. has little effect on most people.C. is affected by economic situation.D. has an impact hard to ignore.17. Lindstrom"s studies imply thatA. only sight is needed for understanding advertising.B. advertisers regard hearing as powerful as sight.C. jingles and slogans can be very powerful in advertising.D. combining sight with hearing can make ads more powerful.18. Which of the following sounds is the most powerful?A. McDonald"s "I"m Lovin" It" jingle.B. The sound of blowing open a door.C. The giggling sound of a baby.D. The hum of a vibrating cell phone.19. To take advantage of sounds in advertising, it"s best toA. invent meaningful sounds.B. use sounds already with associations.C. bestow sounds with meaning.D. play them repeatedly to gain meaning.20. The last paragraph indicates the meaning of a sound originates fromA. cultural influences.B. advertisers" reinforcement.C. our nervous system.D. the sound itself.。

神经语气词心理分析1简单介绍在日常对话中,我们会下意识地对一个人说话的方式进行评价,我们有时会喜欢或讨厌一个人的腔调。
这时候,我们是在讨论韵律(prosody)。
韵律包括了音高和响度的变化,以及音节、单词和短语的长度变化等。
这些参数能够帮助我们表达各种情绪和态度,这些韵律被称为情感韵律。
除此之外,韵律还蕴含着语言学的信息,例如句末升调可以表示询问,重音参与了很多种语言的词汇加工(例如英语),音调参与了很多音调语言(例如中文)的加工等等,这些韵律被称为语言韵律。
早期对于失语症患者的研究发现,就算是左侧大面积损伤的患者在进行无意义表达时,依然可以通过韵律来表达信息,因此研究者认为右半球韵律加工中起到重要作用。
之后一系列的偏侧化研究发现,长时声调变化的加工往往向右偏侧化,短时的则向左偏侧化,这和之前言语感知中双通道理论早期加工的时间不对称性质一致。
这篇笔记从情感韵律和语言韵律两个角度讨论语言中的韵律加工。
需要注意的是,这一部分并没有像言语生成和理解那样有一些完善的框架,只有一些单一的理论,所以整体的逻辑并没有很严密。
2情感韵律2.1情感韵律的知觉情感韵律感知常常被认为与情商相关。
当我们听到一句话时,即使使用了陌生的语言,我们也可以了解到说话者的内心是平静还是兴奋、积极还是消极。
但大脑是怎么加工情感韵律的呢?目前已发现有五个主要脑区参与了加工,它们分别是:右侧STG中部和前部、杏仁核、右侧额顶皮层腹侧、基底节与双侧眶额皮层、额下皮层。
右侧STG中部和前部:听觉整合首先,Beaucousin发现,当被试听到有情感的语句时,STG中部和前部以及STS位置右半球的激活比左半球更大[1]。
该实验采用情绪分类的范式,让被试将机器生成的语音和演员说的有情感的语音进行情绪分类。
另一研究指出,这个区域从早期加工中接受到信息后,其对于情绪语音的反应程度与整体的声音参数显著相关,但是不能被某个声音参数单独解释,说明其主要通过整合不同的声音参数来理解情绪。

Or that you ' d give anything for a whole day to catch up with yourself? Well, here are some ideas that work for me.First of all, make a to-do list every day and set clear priorities. The trick here isn ' t making the list; that' s the easy part. The trick is making the priorities. I look at my list and put a star next to anything that is really urge nt. Then I put the nu mber “ 2” n ext to anything that will just take a couple of minu tes. I actually do these quick tasks before I get on with the urge nt on es; it ' s a bit like clearing off the top of your desk before sitting down to write that important letter.Second, know whe n is the most productive time of day for you and do your work or study then. One of the shock ing discoveries I made about myself is that if I get up at 5 a.m., I can do a day' s work and even fit breakfast in before half past nine. Of course, if you are an early bird, it can be difficult to accomplish tasks that involve phoning “ night owls ” , but that ' s what email' s for!Fin ally, do no t let your in box run your life. I just realized recen tly how freque ntly Iin terrupted my real work to check my in box and resp ond to the most trivial of emails. So, now I only ope n it whe n absolutely n ecessary and this saves me hours. If your work depe nds on you being constantly accessible by email, then you can ' t do this; but be honest and ask yourself,“Am I an email addict? ”With these simple, practical tech niq ues, you will become more efficie nt, less stressed and be able to win some “ me-time ” for yourself.1Q: What tasks docs the speaker tend to do first every day?A The quick tasks.2Q: How to work more efficiently according to the speaker?C Make ug巳of your most productive time of day.3Q: How does the speaker deal with emails now0D TTc opens his inbox only when it's necessary;4Q: What is the purpose of the talk?C To give some tips on how to manage time.Short con versatio nsCon versatio n 1W: So this is your last year in college. Have you ever thought about what you ' d like to do after graduati on?M: Well, I really don ' t know. The job market seems to be improving, so I may look for a job somewhere. But I am also in terested in appl ying for graduate school.Q: What are the two speakers talk ing about?Con versatio n 2M: Do you remember Linda we met a while ago at Susan ' s birthday party?W: Lin da? Do you mean the lady who you said was a nurse in the com mun ity hospital before her retireme nt? Yeah, I remember. She looks very young for her age.Q: What does the woma n think of Lin da?Con versatio n 3M: I wish I could retire tomorrow. Then I would not need to worry about work.W: I don ' t look forward to retirement. I ' m afraid of getting old —my body will slow down, and my childre n will be away. I dread los ing in depe ndence and liv ing in Ion eli ness.Q: What makes the woma n afraid of gett ing old?Con versatio n 4W: I con sider my early 20s to be the prime time of my life.

The best thing is that you have a wealth of opport un ities to explore.Q: What does the man like best about being in his early 20s?Con versatio n 5W: Hi, John. You are taking Law 201 this semester, right? How do you like it?M: Yeah, it' s a great class. We' ve looked at several cases of age discrim in ati on at work.

OK! I want a high-pay ing job, a husba nd with a perfect face and body, and abig house ... with a swim ming pool!M: Wow, Nancy! Those are your three wishes?W: Of course! If I have those three things, I ' II be happy!M: Now, Nancy. Let me tell you my story, and you may see things differently.W: “ See things differently? ” What do you mean, Uncle Charlie?M: Here is what I once experieneed in life. When I married, 32 years ago, we had a happy marriage, a beautiful house, two expensive cars, and $200,000 in the bank!W: See, just like now!M: Wait! I would suggest three differe nt wishes!W: Well ... What would you wish for? You ' re older and wiser!M: What happens if you lose your job, lose your house, and your husband becomes sick? I suggest these three wishes: patie nee, courage and love!W: Patie nee, courage and love?M: Yes! If you have patie nee and courage, you and your husba nd will have good jobs and a nice house. And if you have true love, you and your husband will be beautiful to each other no matter how old you become together.W: This is good.M: With in six years of our marriage, we had three beautiful childre n, but we lost our jobs, our house, all our money, and then I got really sick for nine years. But we didn ' t lose anything truly valuable, because we always said: “Wherever the five of us are together, we are at home! ” An d, little by little things did improve, and I fin ally got well.

Its members are a group of Christia ns known as the Seven th-day Adve ntists. The Adve ntists enjoy a much higher life expecta ncy tha n average Califor nians. Adve ntist men can expect to live about seve n years Ion ger tha n other California n men. Adve ntist wome n are likely to live around four years Ion ger tha n other California n wome n. The Adve ntists also act much youn ger tha n they are and see doctors much less tha n ordinary people.So what' s the secret of the Adventists ' Iongevity? It is not all in their genes. Nor is their good health a mere accide nt. The Adve ntists live Ion ger partly because they have a vegetable-based diet.Around 35 perce nt of them are vegetaria n, and around one half eat meat only rarely. Tobacco and alcohol consumptions are discouraged. So are rich or spicy foods, meat, and drinks containing caffe ine. The Adve ntist diet is high in fruit and vegetables. It also in cludes ple nty of whole gra ins, nu ts, seeds and bea ns, and water is the drink of choice.The Iongevity of the Adventists is also related to their lifestyle and natural environment. They believe in having regular exercise, helping others, and maintaining strong social and familial ties. They live in a mild climate with warm summers and cool winters. Interestingly, the air quality of Loma Lin da, however, is not as good as in other Ion gevity hot spots. This should give us all hope, as it suggests that we don ' t have to have every single factor in place in order to achieve excellent health. Despite this, the Adventists ' good health certainly provides strong evidenee that diet and lifestyle choices have a great impact on health and Ion gevity.1Q: In what way are the Adventists different from ordinary people?B They live their whole lives in a mountain,2Q: How much longer do Adventist women expect to live than other Californian women?C About three years.3Q: What is characteristic ofthc Adventists7 diet?D It is high in fruit, vegetables and whole grains.4Q: What is the main idea of the passage?A Diet and lifestyle are crucial to good health.W: I really need a holiday, so I' m going camping with some friends. What are you doing over the semester break?M: I have n ' t got any pla ns yet. I don ' t really have eno ugh money to fly home.

But you have to hurry if you want to see the exhibits and find out about being lazy because the exhibiti onlasts only for one week. The unu sual show displays a whole range of things such as sofas, beds and anything that makes you feel like tak ing a rest. There are also ple nty of televisi ons for those visiting couch potatoes to watch as they move around relaxingly in the museum.It is no coincidence but rather an intentional decision for the museum to have opened right after the holiday seas on. The idea is for people to think about laz in ess, and perhaps cha nge their behavior and lifestyle throughout the rest of the year. It offers a practical experience to make us think about laz in ess in our high-speed, fast-paced societies.The museum' s foun der Marcela Arrieta said she wan ted people to rethink about laz in ess and decide whether it really is a bad thing. She told the media that people today always think about lazin ess as an en emy of work. For example, they may feel guilty if they sleep late, or they may feel they are wasting time after taking a nap or having a holiday.Ms. Arrieta may not be propos ing that we should have a shorter work ing week, but she could have a point in that we do n eed more leisure time tha n our jobs allow us, and cha nge our lifestyle to a type that is more relax ing. Besides, accord ing to scie ntists, avoidi ng the pressure and stress ofwork can make us healthier and live Ion ger. So, why not try out Ms. Arrieta ' s advice for yourself, slow dow n, and think about being lazy?1Q: Why should visitors be hurried if they want to see the exhibits in (he new museum in Colombia^ capital?B Because the exhibition will last for no more than a week,・2Q: What are exhibited in the new museum?C Beds and sofas that you can try out.3Q: What is the purpose of the exhibition?A It provides a practical experience for us to think about laziness.4Q: What did the museum^ founder advise us to do?C Sit down, relax and be la2y for a while.M: I think the government could provide some money for homeless people to build their own homes. Homeless people would find it easier to get jobs if they had an address.W: It' s not a bad idea. But I wonder where the money will come from.Q: What does the man think the gover nment could do?Con versatio n 2W: You see, some colleagues are not as active and efficie nt as usual and few have made any progress in their bus in ess recen tly.M: Why don ' t we organize some social activities, such as a baseball match? Our colleagues canlearn to help and cooperate with one ano ther.Q: What does the man suggest to cha nge the situati on?Con versatio n 3W: I n eed to go across tow n, but the traffic is so heavy at this time of day.M: When you take the subway, you don ' t have to deal with traffic.

It is based on a survey of 5,000 US households. It showsa drop in satisfaction in many aspects of an employee ' s work life, including interest in the job, dealing with co-workers and bosses, commuting and job security. As a group, neither young people who are just en teri ng the workforce nor employees who are about to retire, Franco says, arehappy with what they do.Only about 36 percent of workers under the age of 25 say they are currently satisfied withtheir jobs. And it' s not much better among baby boomers. Twenty years ago, more than 50 perce nt of baby boomers were satisfied. Today, that ' s down to 46 percent.The most satisfied group of workers in the survey was those aged 25 to 34. Franco suggeststhat they may see some opport un ities for upward mobility as baby boomers retire.The Conference Board survey also asked about the reas ons beh ind job dissatisfact ion. There are econo mic reas ons such as wages, promotio n policy and bonus policy that are sort of addi ng tothis level of dissatisfacti on. In additi on, workers are also dissatisfied with the ben efits: vacati on policy, family-related leave time, work schedule flexibility, and a variety of other factors as well.IQ: Whin negative effect can be caused by workers' discontent?

Left or right?An overview of some research into liberalization: the dominance of one side of the body over the otherACreatures across the animal kingdom have a preference for one foot, eye or even antenna. The cause of this trait, called liberalization, is fairly simple: one side of the brain, which generally controls the opposite side of the body, is more dominant than the other when processing certain tasks. This does, on some occasions, let the animal down: such as when a toad fails to escape from a snake approaching from the right, just because its right eye is worse at spotting danger than its left. So why would animals evolve a characteristic that seems to endanger them?BFor many years it was assumed that liberalization was a uniquely human trait, but this notion rapidly fell apart as researchers started uncovering evidence of liberalization in all sorts of animals. For example, in the 1970s, Lesley Rogers, now at the University of New England in Australia, was studying memory and learning in chicks. She had been injecting a chemical into chicks brains to stop them learning how to spot grains of food among distracting pebbles, and was surprised to observe that the chemical only worked when applied to the left hemisphere of the brain. That strongly suggested that the right side of the chicks brain played little or no role in the learning of such behaviours. Similar evidence appeared in songbirds and rats around the same time, and since then, researchers have built up an impressive catalogue of animal liberalization.CIn some animals, liberalization is simply a preference for a single paw or foot, while in others it appears in more general patterns of behaviour. The left side of most vertebrate brains, for example, seems to process and control feeding. Since the left hemisphere processes input from the right side of the body, that means animals as diverse as fish, toads and birds are more likely to attack prey or food items viewed with their right eye. Even humpback whales prefer to use the right side of their jaws to scrape sand eels from the ocean floor.DGenetics plays a part in determining liberalization, but environmental factors have an impact too. Rogers found that a chick's liberalization depends on whether it is exposed to light before hatching from its egg - if it is kept in the dark during this period, neither hemisphere becomes dominant. In 2004, Rogers used this observation to test the advantages of brain bias in chicks faced with the challenge of multitasking. She hatched chicks with either strong or weak liberalization, then presented the two groups with food hidden among small pebbles and the threatening shape of a fake predator flying overhead. As predicted, the birds incubated in the light looked for foodmainly with their right eye, while using the other to check out the predator. The weakly-lateralized chicks, meanwhile, had difficulty performing these two activities simultaneously.ESimilar results probably hold true for many other animals. In 2006, Angelo Bisazza at the University of Padua set out to observe the differences in feeding behaviour between strongly-lateralized and weakly-lateralized fish. He found that strongly-lateralized individuals were able to feed twice as fast as weakly-lateralized ones when there was a threat of a predator looming above them. Assigning different jobs to different brain halves may be especially advantageous for animals such as birds or fish, whose eyes are placed on the sides of their heads. This enables them to process input from each side separately, with different tasks in mind.FAnd what of those animals who favour a specific side for almost all tasks? In 2009, Maria Magat and Culum Brown at Macquarie University in Australia wanted to see if there was general cognitive advantage in liberalization. To investigate, they turned to parrots, which can be either strongly right- or left-footed, or ambidextrous (without dominance). The parrots were given the intellectually demanding task of pulling a snack on a string up to their beaks, using a co-ordinated combination of claws and beak. The results showed that the parrots with the strongest foot preferences worked out the puzzle far more quickly than their ambidextrous peers.GA further puzzle is why are there always a few exceptions, like left-handed humans, who are wired differently from the majority of the population? Giorgio Vallortigara and Stefano Ghirlanda of Stockholm University seem to have found the answer via mathematical models. These have shown that a group of fish is likely to survive a shark attack with the fewest casualties if the majority turn together in one direction while a very small proportion of the group escape in the direction that the predator is not expecting.HThis imbalance of liberalization within populations may also have advantages for individuals. Whereas most co-operative interactions require participants to react similarly, there are some situations - such as aggressive interactions - where it can benefit an individual to launch an attack from an unexpected quarter. Perhaps this can partly explain the existence of left-handers in human societies. It has been suggested that when it comes tohand-to-hand fighting, left-handers may have the advantage over the right-handed majority. Where survival depends on the element of surprise, it may indeed pay to be different.Questions 27-30Complete each sentence with the correct ending, A-F, below.Write the correct letter, A-F, in boxes 27-30 on your answer sheet.27 In the 1970s, Lesley Rogers discovered that28 Angelo Bisazza’s experiments revealed that29 Magat and Brown’s studies show that30 Vallortigara and Ghirlanda’s research findings suggest thatA liberalization is more common in some species than in others.B it benefits a population if some members have a different liberalization than the majority.C liberalization helps animals do two things at the same time.D liberalization is not confined to human beings.E the greater an animal’s liberalization, the better it is at problem-solving.F strong liberalization may sometimes put groups of animals in danger.Questions 31-35 Complete the summary below.Choose ONE WORD ONLY from the passage for each answer.Write your answers in boxes 31-35 on your answer sheet.Lesley Rogers’ 2004 Experimentliberalization is determined by both genetic and 31__________ influences.

Right rolandic activation during speech perception in stutterers:a MEG studyKatja Biermann-Ruben,a,*Riitta Salmelin,b and Alfons Schnitzler aa Department of Neurology,MEG Laboratory,University of Duesseldorf,GermanybBrain Research Unit,Low Temperature Laboratory,Helsinki University of Technology,FinlandReceived 17May 2004;revised 9August 2004;accepted 19November 2004Available online 10February 2005The focus of our magnetoencephalographic (MEG)study was to obtain further insight into the neuronal organization of language processing in stutterers.We recorded neuronal activity of 10male developmental stutterers and 10male controls,while they listened to pure tones,to words in order to repeat them,and to sentences in order to either repeat or transform them into passive form.Stimulation with pure tones resulted in similar activation patterns in the two groups,but differences emerged in the more complex auditory language tasks.In the stutterers,the left inferior frontal cortex was activated for a short while from 95to 145ms after sentence onset,which was not evident in the controls nor in either group during the word task.In both subject groups,the left rolandic area was activated when listening to the speech stimuli,but in the stutterers,there was an additional activation of the right rolandic area from 315ms onwards,which was more pronounced in the sentence than word task.Activation of areas typically associated with language production was thus observed also during speech perception both in controls and in stutterers.Previous research on speech production in stutterers has found abnormalities in both the amount and timing of activation in these areas.The present data suggest that activation in the left inferior frontal and right rolandic areas in stutterers differs from that in controls also during speech perception.D 2004Elsevier Inc.All rights reserved.Keywords:Stutterer;Speech;Rolandic activationIntroductionStuttering is primarily a motor speech disorder that affects about 1%of the population,with men being affected three to four times more often than women (Starkweather,1987).Many techniques that may improve speech performance of stutterers have been known for decades—such as external timing of speechflow (Brady,1969),suppression or alteration of acoustic feedback of speech (Cherry et al.,1955;Natke,2000;Neelley,1961)or chorus reading (Johnson and Rosen,1937)but the neural mechanisms underlying language processing in stutterers have only been investigated with modern imaging techniques (PET,MRI,MEG)during the past 10years.According to two PET studies,brain metabolism during rest does not differ between stutterers and controls (Braun et al.,1997;Ingham et al.,1996).During stuttering,neuronal activity is stronger in speech-motor-related brain areas than during fluent speech,particularly in the right hemisphere (Braun et al.,1997;Fox et al.,1996,2000).Furthermore,in fronto-temporal and temporo-parietal areas of the left hemisphere there is less activation during stuttering than during induced fluency and,in general,less activation in stutterers than in fluent speakers (Braun et al.,1997;Fox et al.,1996,2000;Wu et al.,1995).Finally,just prior to overt reading of single words,stutterers show an unusual time course of activation in the left inferior frontal speech planning area and left rolandic motor executive areas as compared with fluent speakers:fluent speakers first activate the inferior frontal area and thereafter rolandic areas,but in stutterers,the order is reversed (Salmelin et al.,2000).A recent MRI study using diffusion tensor imaging revealed that stutterers show structural differences in the left rolandic operculum in terms of less fiber coherence within this region,which may contribute to the observed differences in timing (Sommer et al.,2002).The aim of the present study was to provide further information about the time course of activation during auditory language processing and speech preparation in stutterers and fluent speakers.On the basis of neuroimaging results described above we expected to detect differences between stutterers and controls in the timing or strength of activation of the left-hemisphere language-related areas and the rolandic areas.Such differences in activation were also assumed to be task dependent:we hypothesized that activation in stutterers increases when the task becomes more complex and requires more articulatory planning.Altered auditory feedback is known to enhance fluency in stutterers,suggesting that the auditory system has a modulating effect on stuttering (e.g.Cherry et al.,1955;Natke,2000;Neelley,1961).Therefore,it is likely that1053-8119/$-see front matter D

speakers and stutterers could be evident already during the reception phase when subjects listen to speech,at least when they know that they have to speak subsequently.We are not aware of any neuroimaging data addressing this question.In the present study,we used whole-head MEG providing high spatial and temporal resolution to non-invasively monitor cortical dynamics during a simple word repetition task and a more complex sentence repetition/transformation task.Materials and methodsSubjectsTen male developmental stutterers(age26–40years,mean30 years)and10fluently speaking male subjects(age26–42years, mean31years)participated in our study.The control subjects had no language or speech disorders,nor did they have a family history of such disorders for at least two generations.None of the control subjects showed signs of stuttering during the entire measurement procedure.All stuttering subjects had participated in at least one therapy,but no subject was in therapy during the year immediately preceding this MEG study.Therapies varied with respect to onset (early childhood to late thirties),duration(2weeks to4years),and therapists(speech therapists,psychologists,physicians,other). Most subjects reported that they had difficulties transferring the therapeutical contents into their daily life and positive results therefore only persisted for a short while.Stuttering severity was classified as mild to moderate in three subjects,moderate to severe in three subjects and severe to very severe in four subjects according to Riley(1972).None of the subjects suffered from any other neurological or otological disease and the mother tongue was monolingually German for all.Handedness of all subjects was tested right dominant with no statistically significant difference between subject groups(Hand–Dominanz Test(Steingru¨ber,1976) Mann–Whitney U test;P=0.597,handedness questionnaire (Annett,1970)U test;P=0.823).Subjects were contacted via newspaper article and were paid for participation.They signed an informed consent.ParadigmsAuditory cortical responses to simple nonspeech tones were determined using alternating stimulation of the left and right ear with1kHz pure tones of50ms duration and15ms rise and fall times.Loudness was individually adjusted for each ear to70dB above hearing threshold.The interstimulus interval(ISI)was randomized between800and1200ms.Auditory stimulation was performed twice,before each of the two language paradigms described below.Each ear was stimulated about150times per measurement.The simple nonspeech tones were used to evaluate basic auditory cortical processing in fluent speakers and stutterers.Two paradigms using acoustically presented language stimuli were performed.The first was a b word-paradigm Q while the second was a more complex b sentence-paradigm Q.In the word-paradigm,subjects heard a binaurally presented single German noun spoken by a female German speaker and digitized at44.1kHz(STIM Audio System,NEUROSCAN,INC). All of the245presented words derived from a stimulus list used in 2000).The words had two(128words),three(107),or four(10) syllables,and had a concrete(48%)or abstract(42%)meaning,or both(10%).Durations ranged from613to1132ms(mean849ms). Five hundred milliseconds after word offset,subjects heard a tone (1kHz,50ms)indicating that they now should repeat the word. The next noun was presented at a constant ISI of4.1s after tone offset.In the sentence-paradigm,subjects heard binaurally presented sentences that consisted of three words(subject–verb–object,e.g., b doctors heal wounds Q).Sentences were spoken and digitized in the same way as words.All of the400presented sentences were different.Sentence duration ranged from1221to2595ms(mean 1854ms).The set of sentences was divided into comparable halves taking into account the distribution of sentence lengths and regularity/irregularity of verbs.Five hundred milliseconds after sentence offset subjects heard either b[we:]Q or b[pe:]Q.Those simuli prompted subjects to repeat the sentence(b[we:]Q for b wiederholen Q,i.e.,repeat)or to transform the sentence into the German passive form(b[pe:]Q for b passiv Q,i.e.,passive,for example b wounds are healed by doctors Q,which is more common in German language than in English).b[we:]Q and b[pe:]Q had a duration of450ms each and differed in sound only by the onset consonant.Both subject groups were randomly divided into halves, one half performing sentence set1with b[we:]Q and2with b[pe:]Q and vice versa.Stimulus onset asynchrony(SOA)between sentence onsets was adjusted to individual speech performance during the measurement,that is,the next sentence was presented only when the subject had completely finished repeating or transforming the previous sentence.Mean SOA was7.8s F 1.7SD for controls(range4.5–30.2s)and9.0s F4.0SD for stutterers(range5.3–103.9s).Data acquisition and data processingA122-channel whole-head neuromagnetometer device was used for this study(Neuromag-122k;Ahonen et al.,1993).MEG signals are associated with synchronous postsynaptic activation in tens of thousands of parallel apical dendrites of pyramidal cells (Ha¨ma¨la¨inen et al.,1993).MEG is most sensitive to electric currents flowing parallel to the skull,that is,fissural activation. Magnetic signals were digitized at397to513Hz depending on the paradigm,filtered between0.03and130Hz and continuously recorded for offline analysis.Eye movements and blinks were recorded with horizontal and vertical electrooculography(EOG) for offline artifact rejection(individually adjusted thresholds, range50to250A V).Mouth movement was measured with lip-electromyography(lip-EMG)for data analysis of the speech production phase(not reported here).Furthermore,two micro-phone signals were recorded,with one directly fed into the AD-converter and stored in the same file with the MEG signals and the other stored on a digital audio tape(TASCAM,TEAC CORPO-RATION).Continuous data was high-pass filtered at0.2Hz offline and averaged to stimulus onset(pure tones,words, sentences).Anatomical MR images were obtained for19subjects. Coordinate systems of MRI and MEG space were aligned using a3D-digitizer(Polhemus Isotrak R)to mark anatomical landmarks that can be easily detected in anatomical MR images(nasion,right and left preauricular points)and small Head Position Indicator (HPI)coils attached to the subject’s head.The HPI coil positionsK.Biermann-Ruben et al./NeuroImage25(2005)793–801 794The averaged data was analyzed using the equivalent current dipole source modeling technique(Ha¨ma¨la¨inen et al.,1993),as previously applied in several studies of language function(e.g., Helenius et al.,1998;Salmelin et al.,2000).Magnetic fields to pure tone stimulation were modeled by sources in each hemisphere about100ms after stimulus onset.For this purpose,20sensors covering each temporal cortex were selected and one equivalent current dipole(ECD)per hemisphere was selected that explained the field best.The source locations were kept fixed while their amplitudes were allowed to vary over time to best account for the field pattern recorded by all122sensors.Euclidean distances between the sources within each hemisphere(1st vs.2nd measure-ment)were calculated to estimate replicability of localization. Differences between groups and hemispheres were tested using a two-way ANOV A with factors group(2)and hemisphere(2).One source was then selected per hemisphere to represent the auditory cortical activation,according to goodness of fit of the source modeling procedure(N85%;mean F SEM96F0.5%).The localization of the sources on the subject’s anatomical MRI was used as an additional criterion to discard sources that were located unreasonably superficial or deep in the brain.Then,these selected source locations in the left and right auditory cortex were kept fixed,while source strengths[nAm,nanoampere-metre]were calculated over time,separately for both measurements.Peak amplitudes of the prominent N100m were taken and correlated between the two measurements to estimate replicability of activation strengths within subjects.Peak amplitudes furthermore were compared between groups for both measurements and hemispheres(ANOV A,between group factor b group Q(2),within group factors b measurement Q(2)and b hemisphere Q(2)).For the two language paradigms,magnetic fields were averaged fromÀ100to1000ms with respect to word onset and sentence onset.Because stuttering did not occur in a sufficient number of trials to obtain a good signal-to-noise ratio for evoked responses, only epochs with subsequent fluent speech were taken into account.The resulting fields were modeled with equivalent current dipoles individually for each subject and task.The process of source modeling consists of a continuous interplay between visual inspection of local signal variations in the measured magnetic response(122sensors),search for dipolar field patterns and an evaluation of how well the model explains the measured field (goodness-of-fit).Neuromagnetic activity is modeled at the times when each dipolar pattern is clearest;for the estimation of a dipole, only those sensors are selected that cover the active area(usually 12to20sensors).A dipole’s location and orientation represent the center of gravity of the active cortical patch and the direction of current flow within this area,respectively.The amplitude of a dipole[nAm]represents the magnitude of cortical activity.The current dipoles were identified one by one in a time interval from0 to1000ms.The goodness-of-fit value ranged between73%and 99%across subjects and analysis intervals.The complete set of sources was brought into a multi-dipole model where the dipole locations and orientations were kept fixed while the amplitudes were allowed to vary to best explain the measured MEG signals.To be evaluated as active and to be included in the further analysis,a dipole’s maximum amplitude had to exceed three standard deviations of its prestimulus base level activation(À100to0ms with respect to word/sentence onset), which corresponds to a probability of approximately99.8%.The resulting sources for word reception and sentence reception subject to make the tasks comparable with respect to source strengths and latencies.When a specific source area(dipole location and orientation)was found to be active in both tasks,we opted for the dipole that was appropriate for both conditions.Guiding criteria were again goodness of fit(%)and resulting interaction with other sources of the model.Interaction was measured as the angle between any pair of dipoles and was not smaller than308.In case a source was calculated only for one language task,we selected it for the combined model.This final receptive model was then applied to both the word and sentence data to determine the time courses of activation in the different source areas.The sources of the receptive model were displayed on the individual subjects’brains.According to anatomical landmarks, that is,sylvian fissure,central sulcus,and bordering gyri,sources of all subjects were then transferred to one representative brain.Regions of interest(ROIs)Sources were clustered interindividually according to anatom-ical criteria as well as source orientation and time course of activation to represent comparable activation in different subjects.A cluster was only used for further analysis if it contained sources from at least five stutterers or five controls.If a subject did not have a source in a defined cluster,the activation was set equal to zero nAm,representing the assumption that the activation was too small to be detected.If one subject had two sources within one cluster,the time courses of these activations were added together. For each cluster,activations were averaged separately for fluent speakers and stutterers for word reception and sentence reception. Time windows of interest(TOIs)Because activations evolved rather slowly,we did not calculate peak amplitudes for statistical comparisons between conditions and groups,but defined time windows of interest(TOIs;Salmelin et al., 2000).Time-locked responses are typically quite sharp within the first few hundred ms after stimulus onset and become temporally more widespread or sustained at longer latencies.Therefore,in each ROI,we searched for time windows where the mean source strengths plus/minus the standard errors of mean(SEM)in stutterers and fluent speakers did not overlap for at least50ms up to latencies of400ms,or for at least100ms at latencies beyond 400ms.This comparison was done separately for the word and sentence tasks.If one TOI was found for only one task,it was also applied for the other task.Within a defined TOI,mean amplitudes were calculated for each subject and task.Statistical evaluationMean amplitudes within certain ROI/TOIs were compared between groups for each ROI/TOI using two-way ANOV A with group(controls,stutterers)as between group factor and task(word, sentence)as within group factor.ResultsPure tone stimulationAuditory responses to simple1kHz tones were obtained in nineK.Biermann-Ruben et al./NeuroImage25(2005)793–801795sources of activation were located in the superior temporal cortex within Heschl’s gyrus or Planum temporale.The source areas were very similar in the two recordings:in the control group,the Euclidean distance between the corresponding sources was 4.5F 0.8mm (mean F SEM)in the right hemisphere and 6.2F 0.7mm in the left hemisphere.For the stutterers,the distance was 7.8F 2.2mm in the right hemisphere and 5.8F 1.8mm in the left hemisphere.There were no significant differences by hemisphere or subject group.Peak amplitudes of the activations to contralateral stimulation did not differ between the two recordings as indicated by a high correlation of 0.96for the right hemisphere sources and 0.95for the left hemisphere sources.Peak amplitudes of stutterers and controls (Table 1)did not differ by group or recording session.Auditory processing up to 100ms as probed by tonal stimulation should thus be comparable in the two subject groups.Auditory word and sentence presentationStutterers performed both tasks almost fluently.Only three subjects stuttered occasionally in the word task (1,12,and 90times).Six subjects stuttered in the sentence task (1to 127times depending on the condition);stuttering occurred more frequently in sentence transformation than repetition (cumulative sum of stuttered trials 266versus 102).Because of insufficient number of stutter events,only fluent epochs were included in the further analysis.Fig.1shows whole-head MEG recordings during word and sentence perception (overlaid)in one representative control subject.The signals are strongest over the temporal areas,with a sharp peak of activation at about 100ms,followed by more sustained activity.MEG data averaged with respect to the onset of word and sentence presentation was analyzed using source modeling procedure as described in Materials and methods.One b reception-model Q was obtained for each subject (5–8sources per subject,mean 6.6).Regions of interest (ROIs)The sources were transferred to one representative brain and they clustered in four main areas in each hemisphere (Fig.2).According to location,direction of current flow,and time course of the sources,we defined a superior-temporal cluster (I,II),a temporo-parietal cluster (III,IV),an inferior-frontal cluster (V ,VI),and a rolandic cluster (VII,VIII).The superior-temporal cluster mainly covers Heschl’s gyrus and Planum temporale,with current flow in the superior-to-inferior direction.The temporo-parietal areawas defined as the area surrounding the posterior part of the Sylvian fissure containing gyrus supramarginalis,gyrus angularis,and gyrus temporalis superior pars posterior.Here,current flow was typically in the posterior-to-anterior direction.The inferior-frontal area was limited by the central sulcus,the inferior frontal sulcus and the anterior ascending part of the Sylvian fissure.The rolandic area mainly contains the precentral but also to some extent the postcentral gyrus,being laterally bordered by the inferior frontal gyrus.Sometimes dipolar sources exceeded the structural borders defining a cluster but had a typical direction of current flow of the sources within that cluster.Direction of current flow was therefore taken as a functional criterion supplementing anatomical criteria for the definition of a cluster.The number of controls and stutterers who had sources in the defined clusters is given in Fig.2.We also found other sources,located outside of these clear clusters,in total 10sources in the left hemisphere and eight sources in the right hemisphere (nine sources from the control group,nine sources from the stutterers).These sources were scattered over various brain areas in a rather unsystematic manner and they were not included in the further analysis.Group mean activation strengths of clustered sources are overlaid for both groups for word and sentence task and separately for all ROIs in Fig.3.There was a transient bilateral activation of the superior-temporal area at about 100ms that was followed by a sustained activation,predominantly in the left hemisphere,which reached the maximum between 400and 600ms.At 200–400ms,bilateral temporo-parietal and inferior-frontal activity was detected in 8–14subjects depending on cluster and hemisphere (details concerning the number of subjects are given in Fig.2).In controls,rolandic activity peaked at about 200ms bilaterally followed by a sustained signal in the left hemisphere up to 1000ms and a rapid decrease in the right hemisphere.In stutterers,left rolandic activity was delayed (word task)with respect to that in controls by about 100ms (see below for evaluation of time windows of interest,TOIs).Furthermore,the right rolandic area showed a persistent activation up to 800ms in the word task and up to 1000ms in the sentence task.The pattern of activation was comparable for word and sentence processing.Time windows of interest (TOIs)We identified five time ranges (in five ROIs)where activation patterns potentially differed between the stutterer and control groups (arrowheads in Fig.3).Three of these time windows of interest (TOIs)stem from comparisons of activation in the sentence task,two result from comparisons within the word task.The TOIs,ROIs,group means,and P values revealed by analyses of variance are given in Table 2,and the results are illustrated in Fig.4.Significant group differences emerged in the left inferior frontal area at 95–145ms and in the right rolandic area at 315–1000ms.In these ROI/TOIs,stutterers had stronger activations than control subjects.Activation of the left inferior frontal ROI at 95–145ms also showed a significant task effect,with clear activation in the sentence task but essentially no signal in the word task.This effect is predominantly caused by the stutterers,as confirmed by post hoc tests of simple effects (planned comparisons;controls:sentence N word,P N 0.50;stutterers:sentence N word,P b 0.01).Furthermore,analysis revealed significant group-by-task interac-tions in the right temporo-parietal ROI at 330–390ms and the left rolandic ROI at 235–330ms.Both interactions resulted from Table 1N100m amplitudes to tone stimulation Measurement Left hemisphere mean (SD)Right hemisphere mean (SD)Controls 1st

source in the cluster is given in K.Biermann-Ruben et al./NeuroImage 25(2005)793–801797with the word task,while in stutterers,the activations increased from word to sentence task.Post hoc planned comparisons revealed no significant differences between groups when each task was tested separately,either in the right temporo-parietal or in the left rolandic area.These results therefore will not be discussed in detail.DiscussionAuditory processing up to 100ms was probed by tonal stimulation,which was performed before both the word and the sentence task.The locations of activated areas and activationstrengths were indistinguishable between the two recordings.No group differences were found between the fluent speakers and stutterers.Differences in the language tasks therefore cannot be directly attributed to basic auditory processing per se.For the language tasks sources of both subject groups mainly clustered in four areas typically referred to as areas of auditory processing (superior-temporal area),language reception (temporo-parietal area),speech preparation (inferior-frontal area),and sensorimotor processing (rolandic area)(for a review of the neuroimaging literature,see Cabeza and Nyberg,2000).For the auditory word task,we used the same words that were used previously in an overt word reading task comparing stutterers and controls (Salmelin et al.,2000).Interestingly,many oftheFig.3.Mean activation strengths [nAm]of clustered sources of stutterers (grey)and controls (black)overlayed for word (left columns)and sentence task (right
