地位与财富的英文名词解释
地位与财富的英文名词解释地位和财富是每个人都向往的东西。
这两个词汇在英语中分别被称为"status"和"wealth"。
本文将对这两个词进行详细解释，探讨其含义、重要性以及他们如何相互影响。
首先，让我们来探究地位这个概念。
地位是一个人在社会中的位置或身份地位，它可以基于多个因素，如财富、职业、教育程度、社交地位以及对他人的影响力等。
地位对于一个人的自尊心和认同感至关重要，它反映了个体在社会层级中的地位和尊严。
地位的高低通常与权力、荣誉和特权相关。
有时候，地位可以通过财富来衡量。
财富是指一个人拥有的金钱、财产和资源的总和。
它可以作为评估一个人经济实力和财务状况的指标。
财富的积累可以提供更多的机会和选择，例如购买奢侈品、享受高品质的生活和为自己和家人提供更好的教育和医疗条件。
然而，财富并非仅仅是数字上的增长，它还与一个人对自己的财务管理能力、投资能力和理财规划有关。
地位和财富之间存在一定的相互关系。
通常来说，财富可以为个体提供更高的社会地位。
财富的积累可以帮助一个人在社会中获得更高的声誉和更多的权力。
然而，地位并不仅仅取决于财富，还受到其他因素的影响，如教育、职业成就、社交关系和个人魅力等。
地位和财富之间并非完全重叠，但它们通常是相互关联的。
地位和财富的重要性是因人而异的。
对于一些人来说，地位可能比财富更重要。
他们更关注自己在社会中的身份认同和对他人的影响力。
这种追求可能会激励个人不断努力，追求更高的职位和社会地位。
而对于另一些人来说，财富可能是衡量成功的主要标准。
他们将财富视为实现自己梦想和目标的工具，追求经济独立和物质享受。
然而，地位和财富并不是人生的唯一目标。
世界上有许多其他方面也值得我们的关注，如家庭、友情、爱情、健康和个人成长等。
人们应该努力在这些方面寻找平衡，以过上富足和满意的生活。
总而言之，地位和财富是人们追求的两个重要概念。
地位是人们在社会中的位置和身份地位，与权力、尊严和影响力相关。

英文当中的集体名词解释
英文当中的集体名词解释英语当中的集体名词解释英语是一门复杂的语言，常常使人感到困惑。
其中一个令人困惑的方面就是集体名词。
集体名词指的是用于表示一组人、动物或物体的词语。
在英语中，我们经常使用一些特殊的名词来描述这些集合。
在这篇文章中，我将探讨一些常见的集体名词以及它们的用法和含义。
首先我们来看一些用于描述人类集合的集体名词。
在英语中，我们使用"team"（团队）来表示一群人共同协作完成任务的情况，比如“a basketball team”（篮球队）或“a project team”（项目组）。
而“crew”（船员）一词则用来表示一群人在一艘船上工作，比如“a film crew”（电影摄制组）或“a cabin crew”（机舱乘务员）。
除了描述人的集合，集体名词也可用于描述动物的集合。
例如，“herd”（兽群）通常用来表示一群生活在一起的动物，比如“a herd of cows”（一群牛）或“a herd of elephants”（一群大象）。
而“flock”（鸟群）用于描述一群飞禽，比如“a flock of birds”（一群鸟）或“a flock of sheep”（一群羊）。
另外，集体名词也可以用来描述物体的集合。
其中，我们非常熟悉的是“pair”（双）这个词，它表示两个物体配对在一起，比如“a pair of shoes”（一双鞋）或“a pair of glasses”（一副眼镜）。
而“set”（套、组）一词则更常用于描述几个物体组合在一起形成一个整体，比如“a set of dishes”（一套碟子）或“a set of tools”（一套工具）。
除了以上提到的常见集体名词，还有一些用于描述特定集合的词汇。
例如，“school”（鱼群）通常用于描述一群鱼，在这个词中我们可以看出这个集体名词与动物的行为特征相关。
同样地，“swarm”（蜂群）用于描述一群蜜蜂，这个词也非常贴切，因为蜜蜂总是以群体的方式工作和生活。
人类学重要名词解释(英文版)
1. Define anthropology. What are the 4 traditional approaches to study anthropology?Anthropology can be defined as the study of human nature, human society, and human history. It is a scholarly discipline that aims to describe what it means to be human. Anything having to do with human beings is of concern to anthropologists.Physical anthropologists see human beings first and foremost as biological organisms.Prehistoric Archaeology involves the excavation and study of the remains of extinct human societies.Anthropological linguistics subdivides language into four specialties: Phonology, the study of the sounds of language; Morphology, the study of the structure of words; Syntax, the study of sentence structure; Semantics, the study of meaning.Cultural anthropology explores the cultural and social world of modern man by means of holism, comparativism and relativism. It tries to find out the special features and similarities between different cultures, and how their religion and customs are related.2. Define ethnography. Give a short description to a minority nationality in China that you know.Following fieldwork, cultural anthropologists usually write about what they have learned in scholarly articles or in books called ethnography. An ethnography is a description of a single culture. Cultural anthropologists are also called ethnographers.Dai nationality has a population of more than 840,000, and live mainly in Xishuangbanna, known as "Land of Peacocks" and Dehong Prefectures in which people believe in Hinayana of Buddhism. They have been long well- known for their peacock dance. To the Dais the peacock is a symbol of good luck, happiness, beauty and honesty. Most of Dai villages are built along rivers with thatch bamboo houses.The Water Splashing Festival, held by the Dai Nationality in the sixth month of the Dai calendar (in the middle of April), is the grandest ceremonial occasion for the Dai. It is also known as the festival for bathing Buddha. The festival is related to the Buddhist legend of dragon sprinkling fragrant showers on Lord Buddha at his birth. The Buddhist legend has gradually been mingled with the customs of the Dai people since their conversion to Buddhism. Currently, the festival is a combination of the Flower Collecting Festival and the Water Splashing Fair.3.Define culture. What is unique of human culture, and why?Culture can be defined as sets of learned behavior and ideas that human beings us both to pursue their interest and to identify the interests they ought to pursue.The human condition is distinguished from that of other living species by culture. Humans have a brain capable of open symbolic thought, and organs such as hands capable of manipulating matters powerfully or delicately, the interaction between human beings and the wider world is deeper than that of any other species and its world. The characteristic human relationship with the wider world makes cultural creation not only possible but necessary for our very survival. (P. 26)Human beings are social by nature. Apart from sucking, grasping, and crying, humans have no instincts or innate responses that would ensure their survival without their learning the culture of the group into which they are born.Culture is learned. We begin learning as infants, from other members of the group towhich we belong. Human beings do not reinvent culture for themselves each generation. They acquire massive chunks of it from the previous generation and on that basis add to what they have received.4. Define Ethnocentrism. Give a short description to any nation or state in the human history you know as an example.Ethnocentrism is the term anthropologists use to describe the opinion that one’s own way of life is natural or correct, indeed, the only true way of being fully human. (a form of reductionism) The degree of ethnocentrism, which is showed by Americans, is higher than any other western country.One of the ethnocentrism examples would be the Nazism. During the Second World War, Germany led by Nazis conquered many countries in Europe and killed millions of people especially Jews, which was a typical example of ethnocentrism5. Define fieldwork. What preparations are involved in the fieldwork?Fieldwork is the classical method of anthropological research in which all anthropological knowledge is grounded. It is the final phase of formal anthropological training . It is also the experience that characterizes and defines the discipline and that anthropologists expect to repeat frequently throughout their careers.The preparations are involved in the fieldwork.1. The anthropologists have to make their final decisions about where they will do their research and on what topic.2. They should prepare for their research by learning all they can about the place and the people they intend to visit, including reading history, government documents, and ethnographies.3.The anthropologists must obtain funding for their research.4.They also must get permission to carry out research in the geographical region chosen.5. Finally, the anthropologists should adapt themselves to the local living conditions and conventions.6. Define illusion. What are the four types of visual illusion? Book-P95For the American anthropologist Gregory, perceptions are symbolic representations of reality, not direct samples of reality. Perceivers must often work very hard to make sense of the visual signals they receive. When they are wrong, they are subject to illusion.Four important types of visual illusion:1. distortion: what you see appears lager or smaller, longer or shorter, etc., than it really is.2 .ambiguity: this visual illusion occurs when the set of visual signals is contrast but the perceiver’s awareness of it flips from one image to another.3. paradox: a contradiction in terms, or at least an image that appears to be visually contradictory.4. fiction: seeing things that are not there.7. Who is Piaget? Say something about him and his achievements. Book-P113Piaget is one of the three major theorists that have a significant influence on anthropological approaches to cognitive development.Piaget placed primary emphasis on the development of reasoning rather than emotion and proposed four stages of development in children’s reasoning powers:The Sensorimotor stage, Preoperational stage, Concrete operation, Formal operation and he contributes his whole life to the achievement—explaining human beings by the viewpoint of biology.8. Define play. What are the main functions of play? Book-P123/Play is a characteristic behavior of mankind at all ages of life that arises from a genetically inherited stimulus or proclivity and is distinguished by the combination of traits of being voluntary, somehow pleasurable, distinct temporally from other behavior, and distinctive in having a make-believe or psychically transcendental quality. There are several main functions of play:⏹source of creativitySince play is about ―what can be‖ not what should be, it cuts both ways. It can be a force for positive creativity or a force for the negative.⏹commentary on the real worldIn the process of playing, children learn that behavior is ―contexted”, that contexts influence the authority structure of relationships, and that these relationships can be commented on.⏹preparation for lifePl ay serves to prepare a person for life and is therefore less serious than ―real life‖ .9. Define deep play. What is the purpose of deep play in primitive and modern culture? List some examples. P128/P130Deep play is play in which the stakes are so high that it is irrational for anyone to engage in it at all.Equally at stake in ―deep‖ matches are esteem, honor, dignity, and respect, which the money represents. These are at stake playfully. The cockfight is a Balinese reflection on violence and those aspects of Balinese culture that are affiliated with it: ―animal savagery, male narcissism‖Deep play is also known in American society. It is suggested that sexual activity without the use of available contraceptives among college students is deep play.10. Define art. What are encompassed in Western culture? What are its functions? P131/P130/P132Alenxander Alland (1977:39) defines art as ―play with form producing some aesthetically successful transformation-representation.‖Art encompasses sculpture, drawing, painting, dance. Theatre, music, and literature as well as processes and products that bear a family resemblance to them such as film, photography, mime, oral narrative, festivals, and national celebrations.Its function includes:1:Reflecting social structure The social structure is the expression of aesthetic principles. 2:Shaping attitudes Art shapes the values, attitudes and emotions of audience and actors outside the theater, who begin to feel, act and think differently in everyday life.3:Commentary on society Art is a transforming commentary on public occasions and on hierarchy to avoid persecution.4:Mediating oppositions Art has the potential to move participants and viewers in the direction of unification of mind, emotion, and body, and to bring about a correction to understanding in the direction of wisdom.5:Communicating Art generates pleasure, reaffirms social bonds, and assists in dissipating tension.11. Define myth. What are the functions of myth? P139/P140Myths are generally defined as sanctified or sacred narratives about past events or aboutevents in the future. In Western society, myths were long thought to be flawed attempts at science or history or were considered delusions.Myth as Charter for Social ActionMyths serve as ―charters‖ or ―justifications‖ for present day social arrangements, i.e. a given myth reinforces some aspect or social life that needs sanctificationMyth as Conceptual ToolMyths are tools for overcoming logical contradictions that cannot otherwise be overcome in a society or indeed in human life.12. Define ritual/rites of passage. How many stages does it contain? And what are they? P141Ritual may be defined as a social practice composed of a particular sequential ordering of symbols in several different modalities, including dance, singing, speech, bodily actions, the manipulation of certain objects, and so on.Rites of Passage were rituals associated with the movement, or passage, of people from one position in the social structure to another: births, initiations, confirmations, wedddings, funerals, and the like.There are three stages in it. The first stage is separation; the second one is transition; the third one is reaggregation. P14113.What does summarizing symbol mean?（归纳符号）Give some examples. Summarizing symbols sum up, express, represent for the participants ―in an emotionally powerful…way what the system means to them.‖For example, to many people the American flag stands for patriotism, democracy, free enterprise, freedom, national superiority, hard work and progress. (To other people, the same flag sums up such things as imperialism, racism, opposition to the legitimate struggle of Third World people, and support for right-wing dictatorships.)14. What does elaborating symbol mean? Please illustrate.Elaborating symbols allow people to sort out complex and undifferentiated feelings and ideas so that they become comprehensible, communicable, and translatable into action.For example, for the Dinka, a cattle-herding people of East Africa. Cattle provide the key to understanding their lives. One of the principal ethnographers of the Dinka points out that cattle provide most of the categories for thinking about and responding to experience. These ranges from perceptions of color, light and shade, which are connected to the colors the Dinka see in cattle. To the structure of their own society which to them is put together as a bull is put together.15. According to the textbook, what does societal metaphor refer to? What have been introduced in the book? What examples have been given?Societal metaphors can be defined as the structure of the universe is the same as the structure of a society. For example: assembly line，parental investment，survival of the fittest Organic metaphors apply the image of the body to social structures and institutions. For example, it is believed that rocks and trees have spirits, or that soda pop machines have a personality that is both malevolent and greedy---greedy pop machinesmen-eating societyfoot of the mountainWeb of life-networkTechnological metaphors include those that employ man-made objects as metaphorical predicates. For example: The eyes are the mirror of the soul.The mind is a great mirror.biological clockComputer metaphors are technological metaphors.For example, brain is the hardware, and culture is the software.16. Define lineage. What are the characteristics of lineage, and how long does it last? Lineage血缘refers to the nature of the social group formed, which are composed of people who believe that they can specify the parent-child links that unite them.The most important feature of lineages is that they are corporate in organization---that is, a lineage has a single legal ―personality‖.In addition, lineages are the primary political associations in the societies.Lineages can endure over time and in a sense have an independent existence. As long as people can remember from whom they are descended, lineages can endure. Most lineages have a time depth of about five generations: grandparental, parental, Ego’s, children’s and grandchild’s generations.17. What is patrilineage? And what further lineages can it be divided?A patrilineage consists of all those people (male and female) who believe themselves to be related to each other because they are related to a common male ancestor by links through men. These lineages are important for political purposes.It can be further divided into: minimal lineage, which is the most basic stage of lineage segmentation; minor lineage; major lineage; maximal lineage.18. Anthropologists have identified two major types of prescriptive marriage patterns in unilineal societies: direct exchange and asymmetrical exchange. Explain the two terms and their differences.(1) Direct exchange. In patrilineal societies, father’s sister’s daughter marriage sets up a pattern of direct exchange, in which a line that has received a wife from another line in one generation provides one back in the next generation.(2) Asymmetrical exchange. Unlike direct exchange systems, this marriage pattern does not balance out—one line always gets wives from the same line and gives wives to a different line. Put another way, women always marry into the line that their father’s sisters m arried into, and men always find wives in the line their mothers came from.19. Explain woman marriage and the Berdache.Among the Nuer and in some other parts of Africa as well, a woman frequently marries another woman and becomes the ―father‖ of the children the wife bears. The female husband must have some cattle of her own to use for bride wealth payments to the lineage of the wife and is there-fore married to her, just as a man would be. The female husband then gets a male kinsman or a friend or neighbor to impregnate the wife and to help with certain tasks around the homestead which the Nuer believe can be done only by men. The Nuer label such a woman as a near man. Indeed, in social life, she is a socially defined man.Among certain Indians of the Plains in the United States, what has been termed a ―flamboyant masculinity‖ was required of men. But not all men were capable of this, or interested in it. Those who were interested in quieter and more peaceful activities became ―men-wome n‖, or berdache. They dressed in women’s clothing, learned women’s activities,and were even able to marry men, usually as a second wife. As with Nuer woman marriage, there was no suggestion that the berdaches’ relationships with their husbands were necess arily sexual, although they might be.20. What is ghost marriage? What is the function of it? P210The Nuer believe that a man who dies without male heirs leaves an unhappy and angry spirit who may trouble his living kin. The spirit is angry because a basic obligation of Nuer kinship is for a man to be remembered through and by his sons: his name must be continued in his lineage. Therefore, a kinsman of the dead man (a brother, a brother’s son) will often marry a woman ―to his name’. Bridewealth cattle are paid in the name of the dead man to the patrilineage of a woman. She is then married to the ghost, but resides with his living kinsman. In the marriage ceremonies and afterward, this kinsman acts as though he were the true husband, and the children produced by the union are referred to as though they were the kinsman’s, but they are not; his children are considered children of the ghost husband.Biological paternity is divorced from legitimacy, and legitimacy is a characteristic of marriage. The essential feature of the ghost marriage is the provision of children to the ghost husband’s lineage, and the formal union between the ghost and the woman takes precedence over the sexual relationships between the ghost’s surrogate and the woman.Function: Ghost marriage serves to establish a continuation of social patterns.21. Define post-marital residence. List all the different patterns you know, and explain the meaning.Once married, a couple must live somewhere.1. Neolocal（新婚夫妇）residence involves the new couple setting up an independent household at a place of their own choosing. Eskimo2. Patrilocal（夫族居地）residence means that when the married couple go to live with (or near) the husband’s father’s family. herding and farm ing societies3. Matrilocal （妻族居地）residence refers to the married couple going to live with (or near) the family in which the wife was raised. (matrilineal) horticultural groups4. Avunculocal residence means that the married couple go to live with the hus band’s mother’s brother. (rare)There are other, even less common patterns of residence:5. ambiocal .the couple alternately resides with the families of both spouses, or chooe which of the families they will live with.6.duolocal(走婚) In which the linage membeiship is so important that husbands and wives to live with their own lineages even after they are married.22.Explain the following terms respectively, and point out where they mostly happen:Monogamy P212（一夫一妻）A form of marriage which allows a person only one spouse. It is the spousal pattern characteristic of the United States and most industrialized nations)Polygyny P212（一夫多妻）In Polygynous societies, there are variations in the number of wives a man may have. In Islam countries, a man is permitted to have no more than four wives.Polyandry P212（一夫多妻）In polyandrous societies, a woman may marry several brothers; or she may marry men who are not related to each other. There are three major regions: Tibet and Nepal, South India and SriLanka, northern Nigeria and northern Cameroon.Polygynandry P213（多夫多妻）Associated polyandrous marriage, in which a woman may marry two, but rarely more than two men, begins monogamously. The second husband is brought into the union later. The woman and her husbands reside together, and work together, although economic resources are held independently. The two men are considered husbands, and fathers to any children produced by the wife.Two husbands and the wife may decide to take another woman into the marriage – often the sister of the wife –which means that the system becomes simultaneously polygynous and polyandrous (polygynandry).This kind of marriage is in the system of the Sinhalese of Sri Lanka. And it is an acceptable marriage variant in parts of the Pacific, among some North and South American Indian groups, and among the Eskimos.23. What are the 4 forms of families? Explain them respectively.(1).Nuclear family --- which is made up of two generations: parents and unmarried children.(2)the polygynous families---- each wife has a relationship with her co-wives as individuals and as a group, and they in turn, individually and collectively, interact with the husband.(3)extended family----In certain societies, three generations are expected to live together –parents, married children, and grandchildren .(4)Joint family ---- which refers to the horizontal extension: brothers and their wives (or sisters and their husbands) live together.。
