小径分岔的花园集 理解

小径分岔的花园集理解英文回答:The garden of the forked paths is a short story written by Argentine writer Jorge Luis Borges. It was first published in 1941 and is considered one of Borges' most famous and influential works. The story revolves around a Chinese spy named Ts'ui Pên wh o creates a labyrinthine garden with multiple paths that branch off in different directions.The garden is described as a complex and intricate place, with paths that twist and turn, leading to various destinations. Each path represents a different possible outcome or future, creating a sense of uncertainty and ambiguity. The concept of the garden serves as a metaphor for the choices and decisions we make in life, and the idea that every choice we make leads us down a different path.The protagonist of the story, Yu Tsun, is a descendantof Ts'ui Pên and is tasked with delivering a secret message to his German handlers during World War I. As he navigates the garden, he realizes that the paths are not just physical but also symbolic, representing the different possibilities and outcomes of his mission. He comes to understand that the garden is a manifestation of Ts'uiPên's philosophy, which emphasizes the interconnectedness of all things and the idea that time is not linear but rather a network of possibilities.Ultimately, the story explores themes of determinism, free will, and the nature of time. It raises questions about the choices we make and the paths we take in life, and whether or not we have control over our own destinies. It challenges traditional notions of cause and effect, suggesting that multiple outcomes can exist simultaneously and that our actions can have far-reaching consequences.In conclusion, the garden of the forked paths is a rich and thought-provoking story that delves into philosophical and metaphysical concepts. It invites readers to contemplate the nature of choice, time, and theinterconnectedness of all things.中文回答:《分岔的花园》是阿根廷作家豪尔赫·路易斯·博尔赫斯创作的一篇短篇小说。

Ramsey模型的基本思想:国民收入()Y F K AL=。
所以经济增长决定于资本存量K、人,口L和劳动有效性A的增长。
在Solow和Ramsey增长模型中,人口L和劳动有效性A的增长率外生给定。
因此,必须研究经济增长与资本存量增长之间的关系。
资本存量的变化源于投资,投资形成于储蓄,所以,储蓄率影响资本存量的变化并进而影响经济增长。
在Solow模型中,储蓄率为外生变量。
但是在Ramsey模型中为内生变量,我们必须分析决定储蓄率的机制。
国民产出(收入)分为消费和储蓄两部分。
所以,分析储蓄必须分析消费。

Happiness is far more than a strong body, a magnificent villa or an around-the-world tour; it is something we need from our heart. However, we can investigate happiness through scientific methods.AWhen we are asked the question Where can we find happiness , it is a puzzle difficult to answer accurately. We can find happiness right in our own home, in our workplace, in school, in the company of our friends, etc. It is up to us to find the ways and means to achieve that happiness each of us seek and long for. However, it is essential to recognize that there is no one absolute way to achieve happiness. People may have different ideaswith regard to the ways of achieving happiness. The following five classifications are perceived by many people as sources of happiness: family and friends, wealth, position, educational achievement and fame.BTo give it a comprehensive definition, happiness is a mental state of well-being characterized by positive or pleasant emotions ranging from contentment to intense joy. A variety of biological, psychological, religious, and philosophical approaches have striven to define happiness and identify its sources. Various research groups, including Positive Psychology, endeavor to apply the scientific method to answer questions about what happiness is, and how we might attain it. While philosophers and religious thinkers often define happiness in terms of living a good life, or flourishing, rather than simply as an emotion. Happiness in this sense was used to translate the Greek Eudaimonia, and is still used in virtue ethics.CWhile the level of physical healthiness is the biggest determinant of happiness, comparison of financial success with others of the same age group is the second largest source of happiness and unhappiness. Financially richer people tend to be happier than poorer people, according to sociological researcher Glenn Firebaugh of Pennsylvania State University. Their research is focused on whether the income effect on happiness results largely from the things money can buy (absolute income effect) or from comparing one s income to the income of others (relative income effect). They present their research in a session paper, tided Relative Income and Happiness: Arc Americans on a Hedonk Treadmill? Firebaugh argues that, in evaluating their own incomes, individuals compare themselves to their peers of the same age. Therefore, a persons reported level of happiness dependson how his or her income compares to others in the same age group. Using comparison groups on the basis of age, the researchers find evidence of both relative and absolute effects, but relative income is more important than absolute income in determining the happiness of individuals in the United States. This may result in a self-indulgent treadmill, because incomes in the United States rise over most of the adult lifespan. They always dissatisfy with the salary. For e_ample, the survey indicates that the students studied in Harvard University e_pect to earn much more money than their classmates rather than care about the e_act amount of the salary.DWe have long been aware that elements from various perspectives of We could contribute to realizing happiness. The Minnesota Study of Twins Reared Apart (MISTRA) has recently conducted a research project, choosing _0 pairs of reared-apart twins as subjects to test their perception of happiness. In an early report of results it was found that, on most measurable psychological traits, the level of welfare between the twins in a set felt is varied instead of being the same or similar. Thus environmental factors may not be the only factor that affects the feeling of happiness significantly. In another investigation, among persons of European ancestry, for psychological features that can be measured, heritability range from about 25 percent to 80 percent. Or, to put it more concretely, from one-fourth to four-fifths of the variation from person to person in such features as IQ, creativity and happiness, is associated with genetic differences between those persons. That indicates that genetic difference may also affect the happiness. Furthermore, neurobiological evidence shows that left and right frontal lobes play different roles in the emotion (MC) (M). Happiness is a type of emotion, a positive one. From the e_periments, happiness and the left prefrontal lobe are combinedtogether. The more active it is, the more positive emotion you sense.EAt the outset of new millennium, a global research had a result that the people living in the modern world were even unhappier. With crises being on the rise these days, finding happiness can be a bit challenging. Despite of all the stresses associated with life, we still do our best to be happy — because being happy is the only way to keep us afloat. Happiness is considered a very important therapy, both physically and mentally. With it, we are inspired to accomplish whatever goals we want to achieve. It s a strong drive that keeps us going and helps us live our life every single day.FThere are many ways to be happy. Spend time with individuals who are dear to you. There is nothing more joyful than to be with the people you love. During the weekends, try to schedule a fun trip for you and your partner, or one for your whole family. Just go somewhere else for a change and enjoy the change of scenery. Do something nice for others. Helping others is a very honorable way to find happiness. If your schedule is too tight for volunteer work, you can just donate a small sum of money or some old clothes or toys to charity. When you eat out, try to be a good tipper to the waiters or the valet who safely parked your car. All these simple things will not only make you happy, but other people as well. Start and end your day with a smile. Smiling is a very powerful gesture. There s no need for words to describe how pleasant it is. If you have a lousy day, smile your way out of the office. When people smile back at you, it will uplift your mood and make you feel better. Spending some time with your friends. A close circle of friends is one of the most important sources of happiness.Questions 1-5The reading Passage has si_ paragraphs A-FChoose the correct heading for paragraphs A-E from the list of headings below.Write the appropriate number, i-i_. in bo_es 1-5 on your answer sheet.

Summary (总结题)正向的选择:Lascaux Cave PaintingsIn Southwest France in the 1940’s, playing children discovered Lascaux Grotto, a series of narrow cave chambers that contain huge prehistoric paintings of animals. Many of these beasts are as large as 16 feet (almost 5 meters). Some follow each other in solemn parades, but others swirl about, sideways and upside down. The animals are bulls, wild horses, reindeer, bison, and mammoths outlined with charcoal and painted mostly in reds, yellow, and browns. Scientific analysis reveals that the colors were derived from ocher and other iron oxides ground into a fine powder. Methods of applying color varied: some colors were brushed or smeared on rock surfaces and others were blown or sprayed. It is possible that tubes made from animal bones were used for spraying because hollow bones, some stained with pigment, have been found nearby.One of the most puzzling aspects of the paintings is their location. Other rock paintings—for example, those of Bushmen in South Africa—are either located near cave entrances or completely in the open. Cave paintings in France and Spain, however, are in recesses and caverns far removed from original cave entrances. This means that artists were forced to work in cramped spaces and without sources of natural light. It also implies that whoever made them did not want them to be easily found. Since cave dwellers normally lived close to entrances, there must have been some reason why so many generations of Lascaux cave dwellers hid their art.Scholars offer three related but different opinions about the mysterious origin and significance of these paintings. One opinion is that the paintings were a record of seasonal migrations made by herds. Because some paintings were made directly over others, obliterating them, it is probable that a painting’s value ended with the migration it pictured. Unfortunately, this explanation fails to explain the hidden locations, unless the migrations were celebrated with secret ceremonies.Another opinion is that the paintings were directly related to hunting and were an essential part of a special preparation ceremony. This opinion holds that the pictures and whatever ceremony they accompanied were an ancient method of psychologically motivating hunters. It is conceivable that before going hunting the hunters would draw or study pictures of animals and imagine a successful hunt. Considerable support exists for this opinion because several animals in the pictures are wounded by arrows and spears. This opinion als o attempts to solve the overpainting by explaining that an animal’s picture had no further use after the hunt.A third opinion takes psychological motivation much further into the realm of tribal ceremonies and mystery: the belief that certain animals assumed mythical significance as ancient ancestors or protectors of a given tribe or clan. Two types of images substantiate this theory: the strange, indecipherable geometric shapes that appear near some animals, and the few drawings of men. Wherever men appear they are crudely drawn and their bodies are elongated and rigid. Some men are in a prone position and some have bird or animal heads.Advocates for this opinion point to reports from people who have experienced a trance state, a highly suggestive state of low consciousness between waking and sleeping. Uniformly, these people experienced weightlessness and the sensation that their bodies were being stretched lengthwise. Advocates also point to people who believe that the forces of nature are inhabited by spirits, particularly shamans* who believe that an animal’s spirit and energy is transferred to them while in a trance. One Lascaux narrative picture, which shows a man with a birdlike head and a wounded animal, would seem to lend credence to this third opinion, but there is still much that remains unexplained. For example, where is the proof that the man in the picture is a shaman? He could as easily be a hunter wearing a headmask. Many tribal hunters, including some Native Americans, camouflaged themselves by wearing animal heads and hides.Perhaps so much time has passed that there will never be satisfactory answers to the cave images, but their mystique only adds to their importance. Certainly a great art exists, and by its existence reveals that ancient human beings were not without intelligence, skill, and sensitivity.13.

金字塔的数学名词解释英文

金字塔的数学名词解释英文The Explanation of Mathematical Terms in English Regarding the PyramidIntroductionThe pyramid, with its majestic and iconic structure, has captured the fascination of humankind for centuries. Not only is it a symbol of ancient civilizations, but it also embodies a sophisticated understanding of mathematics. In this article, we will explore and decode various mathematical terms related to the pyramid in English.The BaseThe base of a pyramid refers to the bottom polygon upon which the whole structure rests. In mathematical terms, it is often referred to as the "base polygon." The base can take different shapes depending on the type of pyramid. For example, a square pyramid has a base in the shape of a square, while a triangular pyramid has a base in the shape of a triangle.The ApexThe apex of a pyramid is the pointy top where all the edges converge. In mathematical terms, it is sometimes referred to as the "vertex" or "tip" of the pyramid. The apex is a critical point because it determines the height of the pyramid.HeightThe height of a pyramid is the perpendicular distance from the apex to the base. In mathematical terms, it can also be called the "altitude." The height can be calculated using various methods, depending on the type of pyramid. For example, in a triangular pyramid, the height can be found by extending a perpendicular line from the apex to the base.Slant HeightThe slant height of a pyramid is the distance from any point on the base to a point on an inclined face, following the surface of the pyramid. In mathematical terms, it is also known as the "generatrix." The slant height is a crucial measurement in determining the lateral area and surface area of the pyramid.Lateral AreaThe lateral area of a pyramid represents the total surface area excluding the base. In mathematical terms, it is the sum of the areas of all the faces, excluding the base. Calculating the lateral area involves finding the area of each face and summing them up. The lateral area is an important value when studying the geometry and volume of the pyramid.Surface AreaThe surface area of a pyramid includes both the base and the lateral area. It represents the total area taken up by the pyramid's faces. In mathematical terms, it is the sum of the lateral area and the area of the base.VolumeThe volume of a pyramid refers to the amount of space enclosed by the pyramid. In mathematical terms, it is calculated by multiplying the area of the base with the height and dividing the result by 3. The volume of a pyramid is often expressed in cubic units and is used to estimate the amount of material needed to construct or fill a pyramid.SimilaritySimilarity is a mathematical concept used to describe the relationship between two objects that have the same shape but possibly different sizes. In the case of pyramids, if the corresponding angles and proportions of the faces are equal, the pyramids are considered similar. Similarity plays a crucial role in various geometric calculations and theories associated with pyramids.ConclusionThe mathematical understanding of the pyramid goes beyond its awe-inspiring structure and ancient symbolism. By exploring and decoding the various mathematical terms related to the pyramid in English, we gain a deeper appreciation for the intricate calculations and measurements involved in studying pyramids. From the base and apex to the height and volume, these terms provide the framework for understanding the mathematical complexities behind these magnificent structures.。

FranciosCusset unfolds his writing in the Academic Enclave in a way that tries to draw a trajectory of American higher education. This trajectory ultimately points to the intrinsic ambiguity that lies at the heart of American university system, the confusion of the real characteristic of American education: whether it is isolated from or closely tied to society?As any other discussions raised by social discourses, this question of American education has its dual character. Although Cusset does not live in America, he is critical enough to notice this duality, as revealed by what he points out “although [American university] is separated from civil society, the university nonetheless maintains a closer link with American political society”(38). With this thought-provoking insight from Cusset, I’m going to analyze the legitimacy of Cusset’s duality from a historical point of view.As it is already mentioned, Cusset points out that there is a duality in the role American university plays in the society. It seems that Cusset reveals the American university from the perspective of both “civil society” and “political society.” In order for us to understand the insight of Cusset, we have to mine into the concept of “political society” and “civil society.” The use of these two terms can be traced back to the political philosopher John Locke, who uses them synonymously. A political society, according to Locke, is a system that men voluntarily entered because of consent on social contract. Because of this consent by all, political society, to some extent, can be seen as the aggregate of all sectors in our society, such as government, business, etc. On the other hand, civil society is often understood as family and private sphere, which is considered the third sector and separated from businessand government. From this respect, it is appropriate to consider civil society as a subset of political society. If this is true, it seems that when Cusset concludes that American university is separated from the society, whi le being the “dramatic relay point” of political society, he has made a logical mistake. However, in order to understand correctly Cusset’s argument, we have to consider the historical background and Cusset’s quotation of Bill Readings.“Bill Readings notes in summarizing the arrival of this ‘posthistorical university’ without any referent-since here excellence itself is, in this logic, a notion with no content”(45). Cusset quotes this phrase by Bill Readings to demonstrate the utilitarian character of “posthistorical university,” which is referred to by Cusset as American university under “corporate culture”. Cusset points out, with Readings word, that American university has become the university of excellence. This university of excellence is so good at absorbing and integrating even what would have threatened its values that it has become nothing more than a machine operated by the market. In other words, university in general has transformed from a site to foster unified national culture into the industry of corporations. According to Cusset, this transformation can be summarized by “learn to earn.” This transformation is embedded in the historical background. The space race that has been given birth by the cold war with USSR, the federal funds for research between 1942 and 1945 all reinforce this transformation. Amongst all of these historical factors, the establishment of what Clyde Barrow calls “military-academic complex” is the one which brings the “civil society” into “political society.” Despite the fundsprovided to university by big corporations, which tends to extract American university out from the civil society and the goal of fostering an unified national culture, Roosevelt’s New Deal forces professors to declare loyalty to government. After WW2, the emphasis on nuclear physics has made the monopolistic role of government on technology increasingly imperative. Under this historical and social background, the political society has gradually breaks away from the civil society, integrating with the government and corporate culture. It seems that the Americna university’s involvement in the 19th century Big Projects such as gene pool mapping has build a close connection with the society, but by no means is this a connection to the formation of a public intellectual field represented by civil society. American university has been incorporated into the corporate culture to serve the interest of political society specifically. As a result, it isn’t unexpected for Cusset to conclude that “the social isol ation of the university was paradoxically reinforced, whereas the new economic and professional realism might have led one to expect the opposite. “Instead of logical contradiction, it is critical for Cusset to consider the American higher education system is both isolated and closely tied to society.。
