Mark your answers on ANSWER SHEET 1. (40 points)Text1Habits are a funny thing. We reach for them mindlessly, setting our brains on auto-pilot and relaxing into the unconscious comfort of familiar routine. ―Not choice, but habit rules the unreflecting herd,‖ William Wordsworth said in the 19th century. In the ever-changing 21st century, even the word ―habit‖ carries a ne gative connotation.So it seems antithetical to talk about habits in the same context as creativity and innovation. But brain researchers have discovered that when we consciously develop new habits, we create parallel synaptic paths, and even entirely new brain cells, that can jump our trains of thought onto new, innovative tracks.But don‘t bother trying to kill off old habits; once those ruts of procedure are worn into the hippocampus, they‘re there to stay. Instead, the new habits we deliberately ingrain into ourselves create parallel pathways that can bypass those old roads.―The first thing needed for innovation is a fascination with wonder,‖ says Dawna Markova, author of ―The Open Mind‖ and an executive change consultant for Professional Thinking Part ners. ―But we are taught instead to ‗decide,‘ just as our president calls himself ‗the Decider.‘‖ She adds, however, that ―to decide is to kill off all possibilities but one. A good innovational thinker is always exploring the many other possibilities.‖A ll of us work through problems in ways of which we‘re unaware, she says. Researchers in the late 1960 covered that humans are born with the capacity to2approach challenges in four primary ways: analytically, procedurally, relationally (or collaboratively) and innovatively. At puberty, however, the brain shuts down half of that capacity, preserving only those modes of thought that have seemed most valuable during the first decade or so of life.The current emphasis on standardized testing highlights analysis and procedure, meaning that few of us inherently use our innovative and collaborative modes of thought. ―This breaks the major rule in the American belief system — that anyone can do anything,‖ explains M. J. Ryan, author of the 2006 book ―This Year I Will...‖ and Ms. Markova‘s business partner. ―That‘s a lie that we have perpetuated, and it fosters commonness. Knowing what you‘re good at and doing even more of it creates excellence.‖ This is where developing new habits comes in.21. The view of Wordsworth habit is claimed by beingA. casualB. familiarC. mechanicalD. changeable.22. The researchers have discovered that the formation of habit can beA. predictedB. regulatedC. tracedD. guided23.‖ ruts‖(in li ne one, paragraph 3) has closest meaning toA. tracksB. seriesC. characteristicsD. connections24. Ms. Markova‘s comments suggest that the practice of standard testing ? A, prevents new habits form being formedB, no longer emphasizes commonnessC, maintains the inherent American thinking modelD, complies with the American belief system25. Ryan most probably agree thatA. ideas are born of a relaxing mindB. innovativeness could be taughtC. decisiveness derives from fantastic ideasD. curiosity activates creative mindsText 2It is a wise father that knows his own child, but today a man can boost his paternal (fatherly) wisdom –or at least confirm that he‘s the kid‘s dad. All he needs to do is shell our $30 for paternity testing kit (PTK) at his local drugstore – and another $120 to get the results.More than 60,000 people have purchased the PTKs since they first become available without prescriptions last years, according to Doug Fog, chief operating officer of Identigene, which makes the over-the-counter kits. More than two dozen companies sell DNA tests Directly to the public , ranging in price from a few hundred dollars to more than $2500.3Among the most popular : paternity and kinship testing , which adopted children can use to find their biological relatives and latest rage a many passionate genealogists-and supports businesses that offer to search for a family‘s geographic roots .Most tests require collecting cells by webbing saliva in the mouth and sending it to the company for testing. All tests require a potential candidate with whom to compare DNA.But some observers are skeptical, ―There is a kind of false precision being hawked by people claiming they are doing ancestry testing,‖ says Trey Duster, a New York University sociologist. He notes that each individual has many ancestors-numbering in the hundreds just a few centuries back. Yet most ancestry testing only considers a single lineage, either the Y chromosome inherited through men in a father‘s line or mito chondrial DNA, which a passed down only from mothers. This DNA can reveal genetic information about only one or two ancestors, even though, for example, just three generations back people also have six other great-grandparents or, four generations back, 14 other great-great-grandparents.Critics also argue that commercial genetic testing is only as good as the reference collections to which a sample is compared. Databases used by some companies don‘t rely on data collected systematically but rather lump together information from different research projects. This means that a DNA database may differ depending on the company that processes the results. In addition, the computer programs a company uses to estimate relationships may be patented and not subject to peer review or outside evaluation.26.In paragraphs 1 and 2 , the text shows PTK‘s ___________.[A]easy availability[B]flexibility in pricing[C] successful promotion[D] popularity with households27. PTK is used to __________.[A]locate one‘s b irth place[B]promote genetic research[C] identify parent-child kinship[D] choose children for adoption28. Skeptical observers believe that ancestry testing fails to__________.[A]trace distant ancestors[B] rebuild reliable bloodlines[C] fully use genetic information[D] achieve the claimed accuracy29. In the last paragraph ,a problem commercial genetic testing faces is __________.4[A]disorganized data collection[B] overlapping database building30. An appropriate title for the text is most likely to be__________.[A]Fors and Againsts of DNA testing[B] DNA testing and It‘s problems[C]DNA testing outside the lab[D] lies behind DNA testingText 3The relationship between formal education and economic growth in poor countries is widely misunderstood by economists and politicians alike progress in both area is undoubtedly necessary for the social, political and intellectual development of these and all other societies; however, the conventional view that education should be one of the very highest priorities for promoting rapid economic development in poor countries is wrong. We are fortunate that is it, because new educational systems there and putting enough people through them to improve economic performance would require two or three generations. The findings of a research institution have consistently shown that workers in all countries can be trained on the job to achieve radical higher productivity and, as a result, radically higher standards of living.Ironically, the first evidence for this idea appeared in the United States. Not long ago, with the country entering a recessing and Japan at its pre-bubble peak. The U.S. workforce was derided as poorly educated and one of primary cause of the poor U.S. economic performance. Japan was, and remains, the global leader in automotive-assembly productivity. Yet the research revealed that the U.S. factories of Honda Nissan, and Toyota achieved about 95 percent of the productivity of their Japanese countere pants a result of the training that U.S. workers received on the job.More recently, while examing housing construction, the researchers discovered that illiterate, non-English- speaking Mexican workers in Houston, Texas, consistently met best-practice labor productivity standards despite the complexity of the building industry‘s work.What is the real relationship between education and economic development? We have to suspect that continuing economic growth promotes the development of education even when governments don‘t force it. After all, that‘s how education got started. When our ancestors were hunters and gatherers 10,000 years ago, they didn‘t have time to wonder much about anything besides finding food. Only when humanity began to get its food in a more productive way was there time for other things.As education improved, humanity‘s productivity potential, they could in turn afford more education. This increasingly high level of education is probably a necessary, but not a sufficient, condition for the complex political systems required by advanced5economic performance. Thus poor countries might not be able to escape their poverty traps without political changes that may be possible only with broader formal education. A lack of formal education, however, doesn‘t const rain the ability of the developing world‘s workforce to substantially improve productivity for the forested future. On the contrary, constraints on improving productivity explain why education isn‘t developing more quickly there than it is.31. The author holds in paragraph 1 that the important of education in poor countries ___________.[A] is subject groundless doubts[B] has fallen victim of bias[C] is conventional downgraded[D] has been overestimated32. It is stated in paragraph 1 that construction of a new education system __________.[A]challenges economists and politicians[B]takes efforts of generations[C] demands priority from the government[D] requires sufficient labor force33.A major difference between the Japanese and U.S workforces is that __________.[A] the Japanese workforce is better disciplined[B] the Japanese workforce is more productive[C]the U.S workforce has a better education[D] ]the U.S workforce is more organize34. The author quotes the example of our ancestors to show that education emerged __________.[A] when people had enough time[B] prior to better ways of finding food[C] when people on longer went hung[D] as a result of pressure on government35. According to the last paragraph , development of education __________.[A] results directly from competitive environments[B] does not depend on economic performance[C] follows improved productivity[D] cannot afford political changesText 4The most thoroughly studied in the history of the new world are the ministers and political leaders of seventeenth-century New England. According to the standard history of American philosophy, nowhere else in colonial America was ―So much6important attached to intellectual pursuits ‖ Accord ing to many books and articles, New England‘s leaders established the basic themes and preoccupations of an unfolding, dominant Puritan tradition in American intellectual life.To take this approach to the New Englanders normally mean to start with the Puritans‘ theological innovations and their distinctive ideas about the church-important subjects that we may not neglect. But in keeping with our examination of southern intellectual life, we may consider the original Puritans as carriers of European culture adjusting to New world circumstances. The New England colonies were the scenes of important episodes in the pursuit of widely understood ideals of civility and virtuosity.The early settlers of Massachusetts Bay included men of impressive education and influence in England. `Besides the ninety or so learned ministers who came to Massachusetts church in the decade after 1629,There were political leaders like John Winthrop, an educated gentleman, lawyer, and official of the Crown before he journeyed to Boston. There men wrote and published extensively, reaching both New World and Old World audiences, and giving New England an atmosphere of intellectual earnestness.We should not forget , however, that most New Englanders were less well educated. While few crafts men or farmers, let alone dependents and servants, left literary compositions to be analyzed, The in thinking often had a traditional superstitions quality. A tailor named John Dane, who emigrated in the late 1630s, left an account of his reasons for leaving England that is filled with signs. sexual confusion, economic frustrations , and religious hope-all name together in a decisive moment when he opened the Bible, told his father the first line he saw would settle his fate, and read th e magical words: ―come out from among them, touch no unclean thing , and I will be your God and you shall be my people.‖ One wonders what Dane thought of the careful sermons explaining the Bible that he heard in puritan churched.Mean while , many se ttles had slighter religious commitments than Dane‘s, as one clergyman learned in confronting folk along the coast who mocked that they had not come to the New world for religion . ―Our main end was to catch fish. ‖36. The author notes that in the seventeenth-century New England___________.[A] Puritan tradition dominated political life.[B] intellectual interests were encouraged.[C] Politics benefited much from intellectual endeavors.[D] intellectual pursuits enjoyed a liberal environment.37. It is suggested in paragraph 2 that New Englanders__________.[A] experienced a comparatively peaceful early history.[B] brought with them the culture of the Old World[C] paid little attention to southern intellectual life[D] were obsessed with religious innovations738. The early ministers and political leaders in Massachusetts Bay__________.[A] were famous in the New World for their writings[B] gained increasing importance in religious affairs[C] abandoned high positions before coming to the New World[D] created a new intellectual atmosphere in New England39. The story of John Dane shows that less well-educated New Englanders were often __________.[A] influenced by superstitions[B] troubled with religious beliefs[C] puzzled by church sermons[D] frustrated with family earnings40. The text suggests that early settlers in New England__________.[A] were mostly engaged in political activities[B] were motivated by an illusory prospect[C] came from different backgrounds.[D] left few formal records for later referencePart BDirections:Directions: In the following text, some sentences have been removed.

(10 points)Coinciding with the groundbreaking theory of biological evolution proposed by British naturalist Charles Darwin in the 1860s, British social philosopher Herbert Spencer put forward his own theory of biological and cultural evolution. Spencer argued that all worldly phenomena, including human societies, changed over time, advancing toward perfection. 41.____________.American social scientist Lewis Henry Morgan introduced another theory of cultural evolution in the late 1800s. Morgan, along with Tylor, was one of the founders of modern anthropology. In his work, he attempted to show how all aspects of culture changed together in the evolution of societies.42._____________.In the early 1900s in North America, German-born American anthropologist Franz Boas developed a new theory of culture known as historical particularism. Historical particularism, which emphasized the uniqueness of all cultures, gave new direction to anthropology. 43._____________ .8Boas felt that the culture of any society must be understood as the result of a unique history and not as one of many cultures belonging to a broader evolutionary stage or type of culture. 44._______________.Historical particularism became a dominant approach to the study of culture in American anthropology, largely through the influence of many students of Boas. But a number of anthropologists in the early 1900s also rejected the particularist theory of culture in favor of diffusionism. Some attributed virtually every important cultural achievement to the inventions of a few, especially gifted peoples that, according to diffusionists, then spread to other cultures. 45.________________.Also in the early 1900s, French sociologist Émile Durkheim developed a theory of culture that would greatly influence anthropology. Durkheim proposed that religious beliefs functioned to reinforce social solidarity. An interest in the relationship between the function of society and culture—known as functionalism—became a major theme in European, and especially British, anthropology.[A] Other anthropologists believed that cultural innovations, such as inventions, had a single origin and passed from society to society. This theory was known as diffusionism.[B] In order to study particular cultures as completely as possible, Boas became skilled in linguistics, the study of languages, and in physical anthropology, the study of human biology and anatomy.[C] He argued that human evolution was characterized by a struggle he called the ―survival of the fittest,‖ in which weaker races and societies must eventu ally be replaced by stronger, more advanced races and societies.[D] They also focused on important rituals that appeared to preserve a people‘s social structure, such as initiation ceremonies that formally signify children‘s entrance into adulthood.[E] Thus, in his view, diverse aspects of culture, such as the structure of families, forms of marriage, categories of kinship, ownership of property, forms of government, technology, and systems of food production, all changed as societies evolved.[F]Supporters of the theory viewed as a collection of integrated parts that work together to keep a society functioning.[G] For example, British anthropologists Grafton Elliot Smith and W. J. Perry incorrectly suggested, on the basis of inadequate information, that farming, pottery9making, and metallurgy all originated in ancient Egypt and diffused throughout the world. In fact, all of these cultural developments occurred separately at different times in many parts of the world.Part CDirections:Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written carefully on ANSWER SHEET 2. (10 points)There is a marked difference between the education which every one gets from living with others, and the deliberate educating of the young. In the former case the education is incidental; it is natural and important, but it is not the express reason of the association.46It may be said that the measure of the worth of any social institution is its effect in enlarging and improving experience; but this effect is not a part of its original motive. Religious associations began, for example, in the desire to secure the favor of overruling powers and to ward off evil influences; family life in the desire to gratify appetites and secure family perpetuity; systematic labor, for the most part, because of enslavement to others, etc. 47Only gradually was the by-product of the institution noted, and only more gradually still was this effect considered as a directive factor in the conduct of the institution. Even today, in our industrial life, apart from certain values of industriousness and thrift, the intellectual and emotional reaction of the forms of human association under which the world's work is carried on receives little attention as compared with physical output.But in dealing with the young, the fact of association itself as an immediate human fact, gains in importance.48 While it is easy to ignore in our contact with them the effect of our acts upon their disposition, it is not so easy as in dealing with adults. The need of training is too evident; the pressure to accomplish a change in their attitude and habits is too urgent to leave these consequences wholly out of account. 49Since our chief business with them is to enable them to share in a common life we cannot help considering whether or no we are forming the powers which will secure this ability.If humanity has made some headway in realizing that the ultimate value of every institution is its distinctively human effect we may well believe that this lesson has been learned largely through dealings with the young.50 We are thus led to distinguish, within the broad educational process which we have been so far considering, a more formal kind of education -- that of direct tuition or schooling. In undeveloped social groups, we find very little formal teaching and training. These groups mainly rely for instilling needed dispositions into the young upon the same sort of association which keeps the adults loyal to their group.Section & Writing10Part A51.

考研真题答题黄金攻略名师点评:认为只要专业课重点背会了,就能拿高分,是广大考生普遍存在的误区。

而学会答题方法才是专业课取得高分的关键。

(一)名词解释答题方法【考研名师答题方法点拨】名词解释最简单,最容易得分。

在复习的时候要把参考书中的核心概念和重点概念夯实。

近5-10年的真题是复习名词解释的必备资料,通过研磨真题你可以知道哪些名词是出题老师经常考察的,并且每年很多高校的名词解释还有一定的重复。

专业课辅导名师解析:名词解释答题方法上要按照核心意思+特征/内涵/构成/案例,来作答。

①回答出名词本身的核心含义,力求尊重课本。

这是最主要的。

以下就是针对考研专业课的一些十分重要的复习方法和技巧。

一、专业课考试的方法论对于报考本专业的考生来说,由于已经有了本科阶段的专业基础和知识储备,相对会比较容易进入状态。

但是,这类考生最容易产生轻敌的心理,因此也需要对该学科能有一个清楚的认识,做到知己知彼。

跨专业考研或者对考研所考科目较为陌生的同学,则应该快速建立起对这一学科的认知构架,第一轮下来能够把握该学科的宏观层面与整体构成,这对接下来具体而丰富地掌握各个部分、各个层面的知识具有全局和方向性的意义。

做到这一点的好处是节约时间,尽快进入一个陌生领域并找到状态。

很多初入陌生学科的同学会经常把注意力放在细枝末节上,往往是浪费了很多时间还未找到该学科的核心,同时缺乏对该学科的整体认识。

其实考研不一定要天天都埋头苦干或者从早到晚一直看书,关键的是复习效率。

要在持之以恒的基础上有张有弛。

具体复习时间则因人而异。

一般来说,考生应该做到平均一周有一天的放松时间。

四门课中,专业课(数学也属于专业课)占了300分,是考生考入名校的关键,这300分最能拉开层次。

例如,专业课考试中,分值最低的一道名词解释一般也有4分或者更多,而其他专业课大题更是动辄十几分,甚至几十分,所以在时间分配上自然也应该适当地向专业课倾斜。

根据我们的经验,专业课的复习应该以四轮复习为最佳,所以考生在备考的时候有必要结合下面的内容合理地安排自己的时间:第一轮复习:每年的2月—8月底这段时间是整个专业复习的黄金时间,因为在复习过程遇到不懂的难题可以尽早地寻求帮助得到解决。

2004年,从广西大学毕业的邓荣志放弃了选调百色的机会和北海卜锋饲料有限公司科技示范员的优厚工作待遇,毅然回乡创业,引来一片哗然。

芦狄村村民张崇兴好意提醒他:“没经过实践,理论高是没有用的。

”还有人嘲笑他:“是在外面混不下去了才跑回来的吧?”靠山吃山,靠水吃水。

“我的家乡适合水产养殖,我学的又是这个专业,所以回来了。

”邓荣志回乡了,更重要的是,他要改变家乡人养对虾靠运气的局面。

对虾养殖风险很大,对环境要求非常高。

以往这里的对虾成活率只有45%,今年,经过冰冻灾害,土地田村的对虾成活率仍然保持在70%以上。

邓荣志一手拉起的协会内部的对虾成活率达到了80%~90%。

今年7月,团中央书记处第一书记陆昊到土地田村调研时,对邓荣志的工作充分肯定。

陆昊在广西农村共青团工作座谈会上表示,西部地区共青团要吸引和凝聚农村青年,就是要以农村青年不甘于贫困的现状为根本动力,以想办法带领青年致富为载体。

邓荣志从小家境不好,是“咬牙”上的高中。

刚刚回乡创业,最难的时候,连饲料和生活费都没有,靠贷款为继。

“中国农村有8亿人口,农村不发展,整个国家的发展就不可能,中国的农村有很大的潜力。

2010试题解析

2010试题解析

一、名词解释(每题6分,共30分)1、观察研究法第一个名词解释便是方法的,纵观试卷也足见方法在专业一里的重要性。

09的方法的题占到很大部分甚至是喧宾夺主,以至于让我认为今年的方法不会考答题,结果还是考了一个简答一个论述,足见其重要性,横观近几年真题也证明北大出题的基本趋于稳定,每年的方法占50分以上,一到两个名词解释,一个简答一个论述。

该题出处,许静《传播学概论》244页。

(说句题外话,我上面说到了没做过笔记,只是考前做了几个专题,方法的我重点做了好几页,也带了这些东西去考试。

观察研究法这个我也做了,杯具的是我的这个笔记本在考试第一天被我忘在了超市的自助存包处。

第二天考前去拿,那会超市还没开门。

以至于我考前没能看一眼,这个答的不是很好。

许书上的五种观察行为我做了笔记但是没记住也没答,估计答上会加分的)。

2、编码/解码理论我说有几个名词解释让我发虚,这就是其中一个,因为这个名解我疏忽了,之前总感觉这个考过了(事实上也考过了,01年),所以没有动手去写一写规范下答案,所以答的不是很好。

北大的确是爱考这种相对的概念,列举一下比如信度/效度、编码/解码、隐喻/转喻、能指/所指、冷媒介/热媒介、丰裕媒介/匮乏媒介。

复习时自己灵活点,多横向总结。

至于出处,不用说了。

3、公共领域这个名词解释也让我发虚,原因同上,考前没动手去完善下答案,以为公共领域这种被提烂了的东西不会再考,毕竟06刚考过。

第3、4这两个名词解释,对应06年的第2、3个,连顺序都没变,足见真题的重要性了吧,北大出题尤其是名解这东西不回避往年考过的,并且启示我们真题并不只是用来看看,同样需要动手写一写,之前的人都说专业课真题同英语不同只需看看不必去做的,我看是有必要了。

公共性、公共领域以及场域理论这方面的东西,广言到批判学派,北大老师是很喜欢的,多看看,推荐武大石义彬那本《单向度超真实内爆》。

4、“两级传播”模式这个不用多说的,郭书上讲的很全了,答出谁提出的,在何种背景下,具体怎么回事就哦了。

2009年考研心理学心理学导论真题试卷_真题(含答案与解析)-交互

2009年考研心理学心理学导论真题试卷_真题(含答案与解析)-交互

2009年考研心理学(心理学导论)真题试卷(总分300, 做题时间180分钟)单选题1.某次抽样调查研究显示,学生每天看电视的时间越多,他们学习成绩越差。

该研究属于( )SSS_SINGLE_SELA因果研究B相关研究C个案研究D纵向研究该题您未回答:х该问题分值: 11.6答案:B在心理学的研究中,因果研究即实验研究,指人为安排两种或多种在某一维度上的不同情境,并把被试随机分配到这些情境中,然后测量其行为,并探寻自变量与因变量之间关系的方法。

相关研究是指判断两个变量、特质或者属性关联到什么程度的研究。

“学生每天看电视的时间”和“他们的学习成绩”之间在发展变化的方向与大小方面存在一定的关系,但该调查不能说明因果关系,这就是一种相关研究。

个案研究是指不使用大样本被试,而只是用个案研究的方法对个体进行各种测量。

纵向研究又称追踪研究,指在比较长的时间内,对被试的心理发展进行系统定期的研究。

故本题选B。

2.机能主义心理学的创始人是( )SSS_SINGLE_SELA詹姆斯B斯金纳C华生D韦特海默该题您未回答:х该问题分值: 11.6答案:A机能主义心理学的创始人是詹姆斯,主张心理学应该研究个体适应环境时的心理或意识的功能,而不应该像构造主义那样,分析意识的元素。

斯金纳和华生均为行为主义的代表人物,韦特海默是格式塔流派的奠基人。

故本题选A。

3.神经元结构中具有信息整合功能的部位是( )SSS_SINGLE_SELA树突B胞体C突触D轴突该题您未回答:х该问题分值: 11.6答案:B神经元的基本作用是接受和传送信息。

它是具有细长突起的细胞,由胞体、树突和轴突三部分组成。

其中,树突的作用类似于电视的接收天线,负责接受刺激,将神经冲动传向胞体。

突触是指一个神经元与另一个神经元彼此接触的部位,它具有特殊的细微结构,这种结构保证了神经冲动借助于神经递质,从一个神经元传递到与它相邻的另一个神经元。

轴突的作用是将神经冲动从胞体传出,到达与它联系的各种细胞。

答案
一、 简答题(每小题 6 分,3 小题共 18 分) 1.(1)基本思想:用假想的简单电荷(像电荷)分布来代替导体(或介质)表面上的感应 电荷(或极化电荷)分布,同时将导体(或介质)去掉,并代之以待求场区的介质;这样做 之后,只要能保持在原导体(或介质)表面所在的位置维持它本来的边界值不变,这时不在 直接求解泊松方程,在无边界的情况下,求解实电荷与像电荷共同产生的场。 (2 分) 理论依据:唯一性定理和叠加原理(2 分) (2)镜像法不可以放置在所求解的区域之内,因为这样引入镜像将使所求区域内的场源分 布发生变化, 进而位函数所满足的微分方程也发生变化, 所求的解不是原问题的解。 (2 分) 2. 引力场基本方程的积分形式
