细胞自噬机制--2016年诺贝尔生理或医学奖

Scientific Background Discoveries of Mechanisms for AutophagyThe 2016 Nobel Prize in Physiology or Medicine is awarded to Yoshinori Ohsumi for his discoveries of mechanisms for autophagy. Macroautophagy (“self-eating”, hereafter referred to as autophagy) isan evolutionarily conserved process whereby the eukaryotic cell can recycle part of its own contentby sequestering a portion of the cytoplasm in a double-membrane vesicle that is delivered to the lysosome for digestion. Unlike other cellular degradation machineries, autophagy removes long-lived proteins, large macro-molecular complexes and organelles that have become obsolete or damaged. Autophagy mediates the digestion and recycling of non-essential parts of the cell during starvation and participates in a varietyof physiological processes where cellular components must be removed to leave space for new ones. In addition, autophagy is a key cellular process capable of clearing invading microorganisms and toxic protein aggregates, and therefore plays an important role during infection,in ageing and in the pathogenesis of many human diseases. Although autophagy was recognized already in the 1960’s, the mechanism and physiological relevance remained poorly understood for decades. The work of Yoshinori Ohsumi dramatically transformed the understanding of this vital cellular process. In 1993, Ohsumi published his seminal discovery of 15 genes of key importance for autophagy in budding yeast. In a series of elegant subsequent studies, he cloned several of these genes in yeast and mammalian cells and elucidated the function of the encoded proteins. Based on Yoshinori Ohsumi’s seminal discoveries, the importance of autophagyin human physiology and disease is now appreciated.The mystery of autophagyIn the early 1950’s, Christian de Duve was interested in the action of insulin and studied the intracellular localization of glucose-6-phosphatase using cell fractionation methods developed by Albert Claude. In a control experiment, he also followed the distribution of acid phosphatase, but failed to detect any enzymatic activity in freshly isolated liver fractions. Remarkably, the enzymatic activity reappeared if the fractions were stored for five days in a refrigerator1. It soon became clear that proteolytic enzymes were sequestered within a previously unknown membrane structure that de Duve named the lysosome1,2. Comparative electron microscopy of purified lysosome-rich liver fractions and sectioned liver identified the lysosome as a distinct cellular organelle3. Christian de Duve and Albert Claude, together with George Palade, were awarded the 1974 Nobel Prize in Physiology or Medicine for their discoveries concerning the structure and functional organization of the cell.Soon after the discovery of the lysosome, researchers found that portions of the cytoplasm are sequestered into membranous structures during normal kidney development in the mouse4. Similar structures containing a small amount of cytoplasm and mitochondria were observed in the proximal tubule cells of rat kidney during hydronephrosis5. The vacuoles were found to co-localize with acid-phosphatase-containing granules during the early stages of degeneration and the structures were shown to increase as degeneration progressed5. Membrane structures containing degenerating cytoplasm were also present in normal rat liver cells and their abundance increased dramatically following glucagon perfusion6 or exposure to toxic agents7. Recognizing that the structures had the capacity to digest parts of the intracellular content, Christian de Duve coined the term autophagy in 1963, and extensively discussed this concept in a review article published a few years later8. At that time, a compelling case for the existence of autophagy in mammalian cells was made based on results from electron microscopy studies8. Autophagy was known to occur at a low basal level, and to increase during differentiation and remodeling in a variety of tissues, including brain, intestine, kidney, lung, liver, prostate, skin and thyroid gland4,7-13. It was speculated that autophagy might be a mechanism for coping with metabolic stress in response to starvation6and that it might have roles in the pathogenesis of disease5. Furthermore, autophagy was shown to occur in a wide range of single cell eukaryotes and metazoa, e.g. amoeba, Euglena gracilis, Tetrahymena, insects and frogs8,14, pointing to a function conserved throughout evolution.During the following decades, advances in the field were limited. Nutrients and hormones were reported to influence autophagy; amino acid deprivation induced15, and insulin-stimulation suppressed16 autophagy in mammalian tissues. A small molecule, 3-methyladenine, was shown to inhibit autophagy17. One study using a combination of cell fractionation, autoradiography and electron microscopy provided evidence that the early stage of autophagy included the formation of a double-membrane structure, the phagophore,that extended around a portion of the cytoplasm and closed into a vesicle lacking hydrolytic enzymes, the autophagosome18 (Figure 1).Despite many indications that autophagy could be an important cellular process, its mechanism and regulation were not understood. Only a handful of laboratories were working on the problem, mainly using correlative or descriptive approaches and focusing on the late stages of autophagy, i.e. the steps just before or after fusion with the lysosome. We now know that the autophagosome is transient and only exists for ~10-20 minutes before fusing with the lysosome, making morphological and biochemical studies very difficult.Figure 1. Formation of the autophagosome. The phagophore extends to form a double-membrane autophagosome that engulfs cytoplasmic material. The autophagosome fuses with the lysosome, where the content is degraded.In the early 1990’s, almost 30 years after de Duve coined the term autophagy, the process remained a biological enigma. Molecular markers were not available and components of the autophagy machinery were elusive. Many fundamental questions remained unanswered: How was the autophagy process initiated? How was the autophagosome formed? How important was autophagy for cellular and organismal survival? Did autophagy have any role in human disease? Discovery of the autophagy machineryIn the early 1990’s Yoshinori Ohsumi, then an Assistant Professor at Tokyo University, decided to study autophagy using the budding yeast Saccharomyces cerevisae as a model system. The first question he addressed was whether autophagy exists in this unicellular organism. The yeast vacuole is the functional equivalent of the mammalian lysosome. Ohsumi reasoned that, if autophagy existed in yeast, inhibition of vacuolar enzymes would result in the accumulation of engulfed cytoplasmic components in the vacuole. To test this hypothesis, he developed yeast strains that lacked the vacuolar proteases proteinase A, proteinase B and carboxy-peptidase19. He found that autophagic bodies accumulated in the vacuole when the engineered yeast were grown in nutrient-deprived medium19, producing an abnormal vacuole that was visible under a light microscope. He had now identified a unique phenotype that could be used to discover genes that control the induction of autophagy. By inducing random mutations in yeast cells lacking vacuolar proteases, Ohsumi identified the first mutant that could not accumulate autophagic bodies in the vacuole20; he named this gene autophagy 1 (APG1). He then found that the APG1 mutant lost viability much quicker than wild-type yeast cells in nitrogen-deprived medium. As a second screen he used this more convenient phenotype and additional characterization to identify 75 recessive mutants that could be categorized into different complementation groups. In an article published in FEBS Letters in 1993, Ohsumi reported his discovery of as many as 15 genes that are essential for the activation of autophagy in eukaryotic cells20. He named the genes APG1-15. As new autophagy genes were identified in yeast and other species, a unified system of gene nomenclature using the ATG abbreviation was adopted21. This nomenclature will be used henceforth in the text.During the following years, Ohsumi cloned several ATG genes22-24and characterized the function of their protein products. Cloning of the ATG1gene revealed that it encodes a serine/threonine kinase, demonstrating a role for protein phosphorylation in autophagy24. Additional studies showed that Atg1 forms a complex with the product of the ATG13 gene, and that this interaction is regulated by the target of rapamycin (TOR) kinase23,25. TOR is active in cells grown under nutrient-rich conditions and hyper-phosphorylates Atg13, which prevents the formation of the Atg13:Atg1 complex. Conversely, when TOR is inactivated by starvation, dephosphorylated Atg13 binds Atg1 and autophagy is activated25. Subsequently, the active kinase was shown to be a pentameric complex26 that includes, in addition to Atg1 and Atg13, Atg17, Atg29 and Atg31. The assembly of this complex is a first step in a cascade of events needed for formation of the autophagosome.Figure 2. Regulation of autophagosome formation. Ohsumi studied the function of the proteins encoded by key autophagy genes. He delineated how stress signals initiate autophagy and the mechanism by which protein complexes promote distinct stages of autophagosome formation.The formation of the autophagosome involves the integral membrane protein Atg9, as well as a phosphatidylinositol-3 kinase (PI3K) complex26 composed of vacuolar protein sorting-associated protein 34 (Vps34), Vps15, Atg6, and Atg14. This complex generates phosphatidylinositol-3 phosphate and additional Atg proteins are recruitedto the membrane of the phagophore. Extension of the phagophore to form the mature autophagosome involves two ubiquitin-like protein conjugation cascades (Figure 2).Studies on the localization of Atg8 showed that, while the protein was evenly distributed throughout the cytoplasm of growing yeast cells, in starved cells, Atg8 formed large aggregates that co-localized with autophagosomes and autophagic bodies27. Ohsumi made the surprising discovery that the membrane localization of Atg8 is dependent on two ubiquitin-like conjugation systems that act sequentially to promote the covalent binding of Atg8 to the membrane lipid phosphatidylethanolamine. The two systems share the same activating enzyme, Atg7. In the first conjugation event, Atg12 is activated by forming a thioester bond with a cysteine residue of Atg7, and then transferred to the conjugating enzyme Atg10 that catalyzes its covalent binding to the Atg5 protein26,28,29. Further work showed that the Atg12:Atg5 conjugate recruits Atg16 to form a tri-molecular complex that plays an essential role in autophagy by acting as the ligase of the second ubiquitin-like conjugation system30. In this second unique reaction, the C-terminal arginine of Atg8 is removed by Atg4, and mature Atg8 is subsequently activated by Atg7 for transfer to the Atg3 conjugating enzyme31. Finally, the two conjugation systems converge as the Atg12:Atg5:Atg16 ligase promotes the conjugation of Atg8 to phosphatidylethanolamine26,32.Lipidated Atg8 is a key driver of autophagosome elongation and fusion33,34. The two conjugation systems are highly conserved between yeast and mammals. A fluorescently tagged version of the mammalian homologue of yeast Atg8, called light chain 3 (LC3), is extensively used as a marker of autophagosome formation in mammalian systems35, 36.Ohsumi and colleagues were the first to identify mammalian homologues of the yeast ATG genes, which allowed studies on the function of autophagyin higher eukaryotes. Soon after, genetic studies revealed that mice lacking the Atg5gene are apparently normal at birth, but die during the first day of life due to inability to cope with the starvation that precedes feeding37. Studies of knockout mouse models lacking different components of the autophagy machinery have confirmed the importance of the process in a variety of mammalian tissues26,38.The pioneering studies by Ohsumi generated an enormous interest in autophagy. The field has become one of the most intensely studied areas of biomedical research, with a remarkable increase in the number of publications since the early 2000’s.Different types of autophagyFollowing the seminal discoveries of Ohsumi, different subtypes of autophagy can now be distinguished depending on the cargo that is degraded. The most extensively studied form of autophagy, macroautophagy, degrades large portions of the cytoplasm and cellular organelles. Non-selective autophagy occurs continuously, andis efficiently induced in response to stress, e.g.starvation. In addition, the selective autophagy of specific classes of substrates - protein aggregates, cytoplasmic organelles or invading viruses and bacteria - involves specific adaptors that recognize the cargo and targets it to Atg8/LC3 on the autophagosomal membrane39. Other forms of autophagy include microautophagy40, which involves the direct engulfment of cytoplasmic material via inward folding of the lysosomal membrane, and chaperone-mediated autophagy (CMA). In CMA, proteins with specific recognition signals are directly translocated into the lysosome via binding to a chaperone complex41.Autophagy in health and diseaseInsights provided by the molecular characterizationof autophagy have been instrumental in advancing the understanding of this process and its involvement in cell physiology and a variety of pathological states (Figure 3). Autophagy was initially recognized as a cellular response to stress, but we now know that the system operates continuously at basal levels. Unlike the ubiquitin-proteasome system that preferentially degrades short-lived proteins, autophagy removes long-lived proteins and is the only process capable of destroying whole organelles, such as mitochondria, peroxisomes and the endoplasmic reticulum. Thus, autophagy plays an essential rolein the maintenance of cellular homeostasis. Moreover, autophagy participates in a variety of physiological processes, such as cell differentiation and embryogenesis that require the disposal of large portions of the cytoplasm. The rapid inductionof autophagy in response to different types of stress underlies its cytoprotective function and the capacity to counteract cell injury and many diseases associated with ageing.Because the deregulation of the autophagic flux is directly or indirectly involved in a broad spectrum of human diseases, autophagy is a particularly interesting target for therapeutic intervention. An important first insight into the role of autophagy in disease came from the observation that Beclin-1, the product of the BECN1gene, is mutated in a large proportion of human breast and ovarian cancers. BECN1 is a homolog of yeast ATG6 that regulates steps in the initiation of autophagy42. This finding generated substantial interest in the role of autophagy in cancer43.Misfolded proteins tend to form insoluble aggregates that are toxic to cells. To cope with this problem the cell depends on autophagy44. In fly and mouse models of neurodegenerative diseases, the activation of autophagy by inhibition of TOR kinase reduces the toxicity of protein aggregates45. Moreover, loss of autophagy in the mouse brain by the tissue-specific disruption of Atg5and Atg7 causes neurodegeneration46,47. Several autosomal recessive human diseases with impaired autophagy are characterized by brain malformations, developmental delay, intellectual disability, epilepsy, movement disorders and neurodegeneration48.Figure 3. Autophagy in health and disease. Autophagy is linked to physiological processes including embryogenesis and cell differentiation, adaptation to starvation and other types of stress, as well as pathological conditions including neurodegenerative diseases, cancer and infections.The capacity of autophagy to eliminate invading microorganisms, a phenomenon called xenophagy, underlies its key role in the activationof immune responses and the control of infectious diseases49,50. Viruses and intracellular bacteria have developed sophisticated strategies to circumvent this cellular defense. Additionally, microorganisms can exploit autophagy to sustain their own growth.ConclusionThe discovery of autophagy genes, and the elucidation of the molecular machinery for autophagy by Yoshinori Ohsumi have led to a new paradigm in the understanding of how the cell recycles its contents. Because of his pioneering work, autophagy is recognized as a fundamental process in cell physiology with major implicationsfor human health and disease.Nils-Göran Larsson and Maria G.

换句话说,凡写出来供宣讲或宣扬的书面材料都叫讲话稿,又称“发言稿”。

一起来看看学校三分钟演讲稿英语作文,欢迎查阅!学校三分钟演讲稿英语作文1Dear teachers and studentsgood morning!My dear students, when you arrive at the school gate every morning, is the bell ringing? Nervous? The answer must be yes! The reason is that everyone will say with one voice: "traffic jam"!The congestion phenomenon is not only felt by us, but also understood by the school! In order to effectively solve the congestion at the school gate during the rush hours of school and school, ensure the students' safe travel, cultivate students' good awareness of abiding by rules and the ability of self-care and self-improvement, maintain the safety of students and create a safe campus, the school proposes that parents pick up and send them to the designated place and queue up to enter the school.Let's tell our parents, send their children to school, do not enter the school gate, this is conducive to the cultivation of children's happy mentality and self-care ability. Don't gather around the school gate to block the passage. It's better to pull over 10 meters away from the school gate and let the children walk into the campus. Do not park at the school gate, so as not to affect the smooth road, hinder traffic, and cause potential safety hazards.When picking up the children, the e_it of the student team should not be blocked, so as not to affect the order and safetymaintenance of the student road team. Please make an appointment with your child in the school's designated pick-up area. Let the children consciously and punctually go to the designated place to find their parents. This can reduce the burden of parents looking for their children.In order to let us grow up safely, healthily, civilly and happily, the school encourages parents to cultivate their children's ability of self-reliance and self-care. On the premise of safety guarantee, parents will pick up their children to designated places and queue up for school.学校三分钟演讲稿英语作文2The man I admire is a white haired grandfather.Speaking of him, I have no deep impression on him. In my eyes, he is just an old man over 60 years old. He never talks. I don't know his name yet. Every time I go to school and school, he cleans the street near my intersection, whether it's windy or rainy.It is this ordinary grandfather who tells the e_traordinary truth. I still remember that day, the grandfather was still sweeping the street. I was walking on the road after school and saw my grandfather sweeping the street. Suddenly, my grandfather coughed. I hesitated for a moment and decided to help him, but he stood up by himself. I was afraid that my grandfather would fall ill, so I asked, "grandfather, why do you sweep the streets every day? Are you a sanitation worker?" he laughed and walked away. The ne_t day, I asked him the same question. "I'm not a sanitation worker," he said solemnly. "I sweep the streets because I want to contribute to society. The reason why I don't leave a name is that no one will remember what you did - e_cept yourself! "I was silent, and I was proud to know such an old man. But forthe ne_t ten days, I didn't see my grandfather. After that, I knew he was dead.Now, selfless dedication has become a "rare species.". We should learn from grandfather's quality - selfless dedication!学校三分钟演讲稿英语作文3School begins, I changed from the fourth grade to the fifth grade now. In the eyes of young students, I'm already a big brother, and I'm also a good e_ample for junior students. I want to give full play to my advantages and leave them a good impression. First of all, I have to change my characters. Although my handwriting is OK, it's a little bit "lopsided". I must change it when it's not serious.I also need to learn how to save. Although the covers we use for wrapping books are getting old, they can be recycled. However, there are still some people who have enough old book covers at home and urge their mother to buy a new one. There are also some people in order to save newspapers or already useless posters wrapped in the cover, and then write __ books. I advocate this practice, which saves parents' or their own money and is durable. There are also stationery, some people clearly have pens at home, but also go outside to buy some back. You know, it's a lot cheaper to use the old one than to buy the new one. Although I am the same, but I will try my best to correct it, because I know that the money of my parents is hard won, and the money is earned by their sweat and labor. Usually we ask our parents for money when we are free, so 1 yuan, 2 yuan, 5 yuan. As time goes by, don't our parents spend all the money they earn from their hard work? Isn't the money parents have made over the years in vain? We should try to spend less of our parents' money.From now on, I will do a little bit of things around me, students have difficulties to help him as much as possible, strive to be the three good students of this semester.学校三分钟演讲稿英语作文4Knowledge collaboration and all-round educationLadies and gentlemen,We engineering students take it for granted that technology is changing incredibly fast. We are thinking nervously and seriously whether our colleges are failing to provide a foundation in the skills currently needed in industry. Take my major telecommunications for e_ample. Scientists say that 21st century is a biomedical time, not an electrical time. But without the help of electronic data processing and transformation, biomedical technology alone cannot go too far. Funny enough, the word biomedical itself is just a combination of two disciplines. So the interdisciplinary e_ploitation serves as the critical part for our electric and electronics world as well as any other fields to find new way of being.But the power of knowledge collaboration is certainly not restricted to science and engineering; it is in the full community of learning. Walking around campus I absorbed a reality that there is a seamless web between students from different professional backgrounds. The engineering students are discussing animatedly in a philosophy lecture, speaking passionately in the public speaking club, and looking for sparkling ideas from learning history and arts. How wonderful that is! That, ladies and gentleman, is just a significant step forward to be well-rounded because once we jump out of the circle we can see the bigger picture.My friends, I hope that you have already got what universityis all about.

用英语介绍诺贝尔和诺贝尔奖小作文全文共6篇示例,供读者参考篇1The Nobel Prize: Celebrating the Brightest MindsHave you ever heard of the Nobel Prize? It's one of the most famous and prestigious awards in the whole world! Let me tell you all about it.The Nobel Prize was started by a very rich scientist named Alfred Nobel way back in 1895. Mr. Nobel was Swedish, and he invented dynamite – that's a powerful explosive that's used in mining and construction. When he died, he left behind most of his money to start a special prize that would be given out every year to people who did amazing things to help make the world better.There are actually five different Nobel Prizes given out each year. One is for Physics, one is for Chemistry, one is for Physiology or Medicine, one is for Literature, and one is for Peace. Wow, that's a lot of different areas!The Physics Prize is awarded to scientists who made incredible discoveries or inventions related to the laws of nature and the physical world around us. Things like gravity, energy, light, and the building blocks of matter like atoms and molecules. It's mindblowing stuff!The Chemistry Prize goes to the chemists whose work advanced our understanding of the materials that make up everything on Earth and in the universe. They study how different elements and compounds behave and react with each other. Their work helps create new medicines, materials, and technologies.The Nobel Prize in Physiology or Medicine is for the doctors and scientists who made groundbreaking achievements in studying the human body and finding ways to fight diseases. Their research has saved countless lives by leading to new treatments and cures.Next up is the Nobel Prize for Literature, which celebrates the brilliant writers and poets from around the globe. The winners composed amazing novels, short stories, plays, and poems that enlightened our minds and touched our hearts with their creativity and mastery of language.Finally, there's the Nobel Peace Prize. This extremely important award goes to people and organizations that worked tirelessly to promote peace, democracy, human rights, and social justice in the world. Some truly heroic individuals have won this prize for their courage and dedication to making our planet a more peaceful and equitable place.Each Nobel Prize includes a shiny gold medal, a diploma explaining why the winner earned the award, and a whole lot of money – several million dollars! It's kind of like winning the lottery, except you have to hugely impact humanity through your accomplishments.The winners are selected by special committees of experts in each field in Sweden and Norway. Thousands of people get nominated every year from all over the world, but only the most brilliant and influential ones are chosen as Nobel laureates. Just being nominated is considered a great honor.The exciting Nobel Prize announcements happen in October, and a lavish awards ceremony takes place in Stockholm, Sweden in December where the new Nobel laureates give speeches and officially receive their prizes. It's a very glamorous event attended by kings, queens, presidents and prime ministers. The Peace Prize is presented separately in Oslo, Norway.Many Nobel Prize winners have changed the course of human history through their groundbreaking work. For example, Marie Curie's pioneering research on radioactivity led to effective treatments for cancer. Dr. Martin Luther King Jr. bravely led the Civil Rights Movement and promoted racial equality through non-violence. Author Gabriel Garcia Marquez enchanted the world with his magical realism novels like One Hundred Years of Solitude.So as you can see, the Nobel Prize honors the very best of human intelligence, creativity, perseverance and achievement. The winners demonstrate that with hard work, passion and a vision for a better tomorrow, one person truly can make an incredible positive impact on our world. Maybe one day you'll even win a Nobel Prize yourself through your own amazing contributions to society! You'd better start thinking big.篇2The Nobel Prize: Honoring the World's Brightest MindsHave you ever heard of the Nobel Prize? It's one of the most prestigious awards in the world, given to people who have made incredible contributions to fields like science, literature, and peace. Every year, some of the smartest and most accomplishedpeople on the planet are honored with this special award. And let me tell you, winning a Nobel Prize is a really big deal!But where did the Nobel Prize come from, and what's the story behind it? Well, it all started with a man named Alfred Nobel. He was a Swedish chemist who lived in the 1800s, and he's best known for inventing dynamite. Yes, that's right – the same stuff that's used in explosives! Now, you might be thinking, "Whoa, how did someone who invented an explosive end up creating a prize for peace and science?"Well, it's a pretty interesting篇3The Remarkable Nobel PrizeDo you know what the Nobel Prize is? It's one of the most prestigious awards in the world, and it's given to people who have made incredible contributions to humanity. Let me tell you all about it!The Nobel Prize was established by a remarkable man named Alfred Nobel. He was born in Sweden in 1833 and grew up to become a successful inventor, engineer, and businessman. Alfred was really smart and loved science, especially chemistry.He invented something called dynamite, which is a powerful explosive. At first, dynamite was used for mining and construction, but it was also used for warfare, which made Alfred very sad.Alfred Nobel never married or had children, so when he died in 1896, he left most of his fortune to establish a very special prize. In his will, he said that the money should be used to award people whose work has been "most beneficial to humankind." That's how the Nobel Prize was born!Every year, the Nobel Prize is given out in six different categories:PhysicsChemistryPhysiology or MedicineLiteraturePeaceEconomic SciencesLet's learn a bit more about each of these categories.The Nobel Prize in Physics is awarded to scientists who have made groundbreaking discoveries or inventions in the field of physics. Physics is the study of matter, energy, and how they interact. Some famous winners include Albert Einstein, Marie Curie, and Stephen Hawking.The Nobel Prize in Chemistry is given to chemists who have made significant contributions to the field of chemistry. Chemistry is the study of matter and the changes it undergoes. Some notable winners include Marie Curie (again!), Linus Pauling, and Ahmed Zewail.The Nobel Prize in Physiology or Medicine is awarded to scientists who have made important discoveries or advancements in the field of medicine or biology. This includes things like finding cures for diseases, developing new treatments, or understanding how the human body works. Some famous winners are Alexander Fleming (who discovered penicillin), Tu Youyou (for her work on malaria treatment), and James Watson and Francis Crick (for discovering the structure of DNA).The Nobel Prize in Literature is given to authors who have produced outstanding literary works. It recognizes writers who have created novels, poems, plays, or other forms of literature that have had a significant impact on the world. Somewell-known winners are Toni Morrison, Gabriel García Márquez, and Kazuo Ishiguro.The Nobel Peace Prize is awarded to individuals or organizations that have worked tirelessly to promote peace and resolve conflicts around the world. Some inspiring winners include Martin Luther King Jr., Mother Teresa, and Malala Yousafzai.Finally, the Nobel Memorial Prize in Economic Sciences is awarded to economists who have made important contributions to the field of economics. This prize was established a bit later than the others, in 1968. Some notable winners are Milton Friedman, Amartya Sen, and Esther Duflo.The Nobel Prize award ceremony is held every year on December 10th in Stockholm, Sweden (except for the Peace Prize, which is awarded in Oslo, Norway). During the ceremony, the winners receive three things: a Nobel diploma, a Nobel medal, and a cash prize. The cash prize is quite substantial, usually around one million US dollars!Winning a Nobel Prize is considered one of the highest honors in the world. It recognizes individuals whose work has truly made a difference and advanced human knowledge and understanding. Many Nobel laureates (the fancy name forwinners) have made discoveries or inventions that have changed the world we live in.So, the next time you hear about the Nobel Prize, remember that it's a very special award that celebrates the incredible achievements of brilliant minds. Who knows, maybe one day you'll even win a Nobel Prize for your own groundbreaking work!篇4The Nobel Prize: Honoring the World's Brightest MindsHave you ever wondered how some of the most amazing discoveries and inventions came to be? Things like the X-ray, radioactivity, the structure of DNA, and so many other incredible advancements that have made our world better? Well, behind all these breakthroughs are brilliant scientists and trailblazers whose hard work and dedication is celebrated through the Nobel Prize.The Nobel Prize is a very prestigious award given out every year to people who have done something truly remarkable and beneficial for humanity. It's kind of like getting a gold star from your teacher, but a million times more important! Let me tell you all about this special prize and the man behind it.Alfred Nobel and His LegacyAlfred Nobel was a Swedish scientist who lived in the 1800s. He came from a family of engineers and inventors and went on to study explosives and invent things like dynamite. While explosives might seem scary, Nobel's inventions were actually used for good purposes like construction and mining.Despite being behind the invention of dynamite, Nobel didn't want to be remembered as a "merchant of death." Instead, he wanted his legacy to have a positive impact on the world. So in his will, he set aside most of his wealth to start the Nobel Prizes!According to Nobel's wishes, the Nobel Prize would be awarded annually to those who "conferred the greatest benefit to humankind" in the areas of physics, chemistry, medicine, literature, and peace. A few years after his death in 1896, the first Nobel Prizes were handed out in 1901. Pretty neat, right?The Nobel Prize CategoriesSo what exactly are these different prize categories all about? Let me break it down for you:Physics Nobel PrizeThis award celebrates groundbreaking discoveries and research in the field of physics. Things like discovering new particles, explaining natural phenomena, or developing important theories can be recognized with the physics Nobel. Famous recipients include Albert Einstein, Marie Curie, and Stephen Hawking.Chemistry Nobel PrizeThe chemistry Nobel honors chemists who have made pioneering contributions to their field through new discoveries or inventions. Creating new materials, understanding chemical processes, and developing useful products can all earn someone this prestigious prize. Some well-known chemistry Nobelists are Linus Pauling, Dorothy Crowfoot Hodgkin, and Tu Youyou.Medicine Nobel PrizePeople whose research and work have led to significant advancements in medicine and improving human health are awarded the medicine Nobel Prize. This could be for discovering a life-saving drug, developing an innovative treatment, or unraveling the mysteries of diseases. Notable laureates include Alexander Fleming (discoverer of penicillin), Frederick Banting and John Macleod (for insulin), and Barry Marshall and Robin Warren (for bacteria causing stomach ulcers).Literature Nobel PrizeThe literature Nobel is a bit different – it recognizes an author's entire body of written work and their contribution to literature rather than a single accomplishment. Novelists, playwrights, poets, and other literary greats whose writing has had a major cultural impact can receive this honor. Famous recipients include Toni Morrison, Gabriel García Márquez, and Rabindranath Tagore.Peace Nobel PrizeLast but certainly not least, the peace Nobel Prize celebrates those who have made outstanding efforts to promote peace and resolve conflicts in the world. This could include negotiating peace treaties, fighting for human rights, or working to end violence and oppression globally. Some inspiring peace laureates are Martin Luther King Jr., Malala Yousafzai, and the United Nations.What an Amazing HonorImagine working your entire life towards making the world a little bit better, and then being internationally recognized for your hard work! Winning a Nobel Prize is such an incredibledistinction - like getting the highest score in the whole school on your toughest exam.Not only is there great prestige and honor associated with a Nobel, but winners also receive a gold medal, a diploma from the King of Sweden, and a cash prize worth millions! The money comes from the fortune that Alfred Nobel left behind, so in a way, his legacy lives on through each year's new laureates.But more importantly than the medal or money, a Nobel Prize immortalizes a person's groundbreaking accomplishments forever. Their name goes down in history books as one of the greatest minds of all time. How cool is that?While most kids probably won't become a Nobel laureate when they grow up, the Nobel Prizes can still inspire us all to work hard, dream big, and never stop learning and exploring the world around us. After all, the next big scientific breakthrough or earth-changing invention could be just around the corner!In my opinion, the Nobel Prize is one of the greatest honors our world has to celebrate the limitless potential of human knowledge, perseverance, and passion to do good. Someday, if I become a scientist or writer or someone who helps make peace between people, I'll be sure to tell the Nobel Committee, "A prize? For me? Aw, shucks!"篇5The Nobel Prize: Honoring the Greatest MindsHi there! My name is Sam, and I'm a 5th grader who loves learning about amazing people who have made the world a better place. Today, I want to tell you all about a very special award called the Nobel Prize. It's given to some of the smartest and most accomplished people on the planet for their incredible work in different fields.But first, who was Nobel? Alfred Nobel was a Swedish scientist who lived from 1833 to 1896. He was really into chemistry and invented a lot of cool things, like dynamite! Yes, the very same stuff used in explosives. At first, dynamite scared people because it was so powerful. But Nobel knew it could be used for good purposes too, like building roads, digging tunnels, and mining.Nobel was a pretty quirky guy. He never married or had kids, and he moved around a lot between different European countries. But he did have a soft side - Nobel loved literature and poetry. He could speak multiple languages fluently and wrote his own novels and plays, although none of them became super famous.When Nobel's brother died in 1888, a newspaper accidentally printed Alfred's obituary instead, calling him the "Merchant of Death" because of his invention of dynamite. This must have been a huge shock to Nobel. He didn't want to be remembered as someone who created things to hurt people. So in his last will, Nobel decided to use his massive fortune to create annual prizes honoring people whose work benefited humanity.The very first Nobel Prizes were awarded in 1901, five years after Nobel's death. They are given out every year on December 10th, the anniversary of when Nobel passed away. Let me tell you about the different prize categories:The Nobel Prize in Physics is probably the coolest one in my opinion! It recognizes outstanding achievements in understanding how the universe works through physical laws and phenomena. Some past winners made groundbreaking discoveries about things like radioactivity, nuclear fission, lasers, and even the Big Bang theory. How awesome is that?The Nobel Prize in Chemistry honors chemists who have done amazing things like discovering new elements, creating life-saving medicines, or figuring out processes to make useful materials. Chemistry seems complicated to me, but it's incrediblehow these scientists unlock the mysteries of atoms and molecules.I find the Nobel Prize in Physiology or Medicine so fascinating. The scientists who receive this award have dedicated their lives to understanding the human body and curing terrible diseases. Just think about how many lives have been saved thanks to their hard work! From developing vaccines to pioneering organ transplants, these achievements aremind-blowing.The Nobel Prize in Literature is awarded to an author who has created incredible novels, poetry, short stories or plays. These writers use beautiful language to express the human experience in creative and thought-provoking ways. Can you imagine being considered one of the best writers in the whole world? That's got to be the biggest honor for a novelist or poet.Lastly, there's the Nobel Peace Prize which is prettyself-explanatory - it celebrates people and organizations that have made outstanding efforts to promote peace and resolve conflicts around the globe. Examples include fighting against racism, protecting human rights, negotiating peace treaties and advocating for nuclear disarmament. Building peace takesimmense courage, so these recipients deserve all the recognition.Aside from receiving a really cool medal, Nobel Prize laureates also get a ton of prize money - can you guess how much? It's a whopping 10 million Swedish kronor, which is over 1 million US dollars! Not too shabby, right? The awards ceremony is held every year on December 10th in Stockholm, Sweden, except for the Peace Prize which is presented in Oslo, Norway. I'd love to attend one day and see the winners give their inspirational speeches.But being a Nobel laureate isn't just about the glitzy prize ceremony. These distinguished individuals have dedicated their entire lives to pursuing knowledge, upholding truth, and serving humanity through their chosen fields. Just imagining their passion, brilliance and perseverance makes me feel motivated to work really hard in school!Whether it's cracking the mysteries of the universe, curing devastating illnesses, creating transcendent art or building lasting peace, Nobel Prize winners show us what's possible when we commit ourselves to understanding our world and making it a better place. They represent the very best of human potential and achievement.I hope learning about the Nobel Prize inspires you as much as it inspires me. While most of us likely won't becomeworld-changing scientists or authors, we can still strive for excellence and use our talents to have a positive impact, no matter how small. Who knows, maybe one of you reading this will even become a Nobel laureate yourself one day! A kid can dream, right? But for now, I'll just keep studying hard, feeding my curiosity, and doing my best to make the world a little bit better in my own way.篇6The Nobel Prize: Celebrating the Greatest MindsHave you ever wondered how some of the most brilliant people in the world get recognized for their incredible achievements? Well, let me tell you about the Nobel Prize – it's like the ultimate award for those who have made groundbreaking contributions to our world!The story behind the Nobel Prize is quite fascinating. It all began with a man named Alfred Nobel, who lived in Sweden a long time ago. Alfred was a scientist, inventor, and businessman who became incredibly wealthy from his inventions, particularly dynamite. Now, you might think dynamite is a strange thing forsomeone to invent, but back then, it was a major breakthrough in the field of explosives.As Alfred grew older, he started thinking about his legacy and how he wanted to be remembered. He didn't want to be known solely as the "dynamite man" but rather as someone who had a positive impact on humanity. So, in his last will and testament, he set aside a large portion of his wealth to establish an annual prize that would honor those who had made outstanding contributions in various fields.And that's how the Nobel Prize was born!Every year, brilliant minds from all around the world are considered for this prestigious award in six different categories: Physics, Chemistry, Physiology or Medicine, Literature, Peace, and Economic Sciences. Let me give you a quick overview of each one:Physics: This prize is awarded to scientists who have made groundbreaking discoveries or advancements in the field of physics, which deals with the study of matter, energy, and the fundamental laws of the universe.Chemistry: Chemists who have made significant contributions to our understanding of the composition, structure,and properties of different substances are honored with this award.Physiology or Medicine: This prize recognizes scientists whose research and discoveries have helped improve our understanding of the human body, diseases, and treatments.Literature: Authors who have produced literary works of outstanding quality and significance are celebrated with the Nobel Prize in Literature.Peace: This award is given to individuals or organizations that have made exceptional efforts to promote peace and resolve conflicts in the world.Economic Sciences: Economists who have developed innovative theories or made important contributions to the field of economics are honored with this prize.Now, let me tell you about some of the amazing people who have received the Nobel Prize over the years!In the field of Physics, one of the most famous recipients is Albert Einstein. You've probably heard of him before – he's the genius who came up with the theory of relativity, which completely changed our understanding of space, time, and gravity.For Chemistry, Marie Curie is a true pioneer. Not only was she the first woman to win a Nobel Prize, but she also won it twice – once for her discoveries in the field of radioactivity, and again for her work on the discovery of two new elements, radium and polonium.In the category of Physiology or Medicine, you might have heard of Alexander Fleming, the scientist who discovered penicillin – the first widely used antibiotic that has saved millions of lives.For Literature, one of the most celebrated authors is Toni Morrison, an American novelist known for her powerful and poetic explorations of the African American experience.The Nobel Peace Prize has been awarded to remarkable individuals like Nelson Mandela, who fought tirelessly against apartheid in South Africa, and Malala Yousafzai, a young Pakistani activist who advocated for girls' education and survived an assassination attempt by the Taliban.And in the field of Economic Sciences, you might be familiar with Milton Friedman, an influential economist who made significant contributions to our understanding of free-market economics and monetary policy.These are just a few examples of the countless brilliant minds who have been honored with the Nobel Prize over the years.Receiving this award is considered one of the highest honors in the world, and it's not just about the fancy medal or the significant cash prize that comes with it (although those are pretty cool too!). The true value of the Nobel Prize lies in the recognition it bestows upon those who have dedicated their lives to advancing human knowledge, improving our world, and pushing the boundaries of what we thought was possible.So, the next time you hear about someone winning a Nobel Prize, remember that it's not just an award – it's a celebration of the incredible achievements of the human mind and spirit. Who knows, maybe one day, you'll be the one making groundbreaking discoveries or creating something that changes the world for the better!。

As time goes on, we become senior high school students. No one is willing to raise his hand to answer teachers’ questions. What a shame! We are afraid of making mistakes or being laughed at.

Dear Sir, Hello! I’m Li Ming, a student from Mingqi High School of Shanghai. As I’ve always been interested in charity, I’m writing to you in the hope that I could be given the 2,000-yuan fund to carry out my project to help children in poverty-stricken areas. My poverty-relief program is divided into three parts. In the initial stage, I’ll try to purchase textbooks for subjects such as English and Maths. Given that new books are usually expensive, I’ll be on the look-out for good-quality second-hand books. The second stage of my program is to recruit high school students who have a strong desire to help pupils in poor areas. Surely they should be armed with relative knowledge to be qualified teachers. Lastly, we will set out for primary schools, which are selected and contacted in advance, to carry out our program. As to how to allocate the money, I’d like to use 1,000 for textbooks, and the rest to pay for the travelling fee of volunteers. I am looking forward to your reply, thanks! Yours, LiHua

Alfred Nobel was cold to material gains and honor, and extremely honest. Once he stated why he was able to won so many honors in a letter: his medals did not come from his invention of dynamite. For example, Swedish government awarded his medal because of his talents in cooking; French government gave his medal because of his good relationship with one French minister; Brazil presented his medal because of becoming a friend of a Brazilian VIP by accident. He also gave us a story in his autobiography in humorous words:Alfred Nobel, his poor life was nearly ended in the hand of a kind-hearted doctor when he came to the earth.Major merits: always keep his hand nail clean and nice-looking by own and never by others.Major shortcomings: no family, low spirit, poor digestion.Only wish: never being buried aliveMost evil: never worship Plutus.Life achievements: noneThis is Alfred Nobel, a person who boasted himself "no achievements" and always kept his nail clean and nice-looking, had created mass material and spiritual property and left us lofty ideology of hardworking, looking down up material gains and honors.。

Influence
Prior to the speech, R. Sandler, Member of the Royal Academy of Sciences, commented, «Mr. John Steinbeck - In your writings, crowned with popular success in many countries, you have been a bold observer of human behaviour in both tragic and comic situations. This you have described to the reading public of the entire world with vigour and realism. Your Travels with Charley is not only a search for but also a revelation of America, as you yourself say: ‹This monster of a land, this mightiest of nations, this spawn of the future turns out to be the macrocosm of microcosm me.› Thanks to your instinct for what is genuinely American you stand out as a true representative of American life.»

Nobel Prize Acceptance Speech

Nobel Prize Acceptance Speech

Nobel Prize Acceptance SpeechMartin Luther King - Nobel Prize Speech on the occasion of the award of the Nobel Peace Peace Prize in Oslo, December 10, 1964Y our Majesty, Y our Royal Highness, Mr. President, Excellencies, Ladies and Gentlemen:I accept the Nobel Prize for Peace at a moment when 22 million Negroes of the United States of America are engaged in a creative battle to end the long night of racial injustice. I accept this award on behalf of a civil rights movement which is moving with determination and a majestic scorn for risk and danger to establish a reign of freedom and a rule of justice. I am mindf ul that only yesterday in Birmingham, Alabama, our children, crying out for brotherhood, were answered with fire hoses, snarling dogs and even death. I am mindful that only yesterday in Philadelphia, Mississippi, young people seeking to secure the right to vote were brutalized and murdered. And only yesterday more than 40 houses of worship in the State of Mississippi alone were bombed or burned because they offered a sanctuary to those who would not accept segregation. I am mindful that debilitating and grinding poverty afflicts my people and chains them to the lowest rung of the economic ladder.Therefore, I must ask why this prize is awarded to a movement which is beleagured and committed to unrelenting struggle; to a movement which has not won the very peace and brotherhood which is the essence of the Nobel Prize.After contemplation, I conclude that this award which I receive on behalf of that movement is a profound recognition that nonviolence is the answer to the crucial political and moral question of our time - - the need for man to overcome oppression and violence without resorting to violence and oppression. Civilization and violence are antithetical concepts. Negroes of the Un ited States, following the people of India, have demonstrated that nonviolence is not sterile passivity, but a powerful moral force which makes for social transformation. Sooner or later all the people of the world will have to discover a way to live together in peace, and thereby transform this pending cosmic elegy into a creative psalm of brotherhood, If this is to be achieved, man must evolve for all human conflict a method which rejects revenge, aggression and retaliation. The foundation of such a method is love.The tortuous road which has led from Montgomery, Alabama, to Oslo bears witness to this truth. This is a road over which millions of Negroes are travelling to find a new sense of dignity. This same road has opened for all Americans a new era of progress and hope. It has led to a new Civil Rights Bill, and it will, I am convinced, be widened and lengthened into a super highway of justice as Negro and white men in increasing numbers create alliances to overcome their common problems.I accept this award today with an abiding faith in America and an audacious faith in the future of mankind. I refuse to accept despair as the final response to the ambiguities of history. I refuse to accept the idea that the "isness" of man's present nature makes him morally incapable of reaching up for the eternal "oughtness" that forever confronts him. I refuse to accept the idea that man is mere flotsom and jetsom in the river of life unable to influence the unfolding events which surround him. I refuse to accept the view that mankind is so tragically bound to the starless midnight of racism and war that the bright daybreak of peace and brotherhood can never become a reality.I refuse to accept the cynical notion that nation after nation must spiral down a militaristic stairway into the hell of thermonuclear destruction. I believe that unarmed truth and unconditional love will have the final word in reality. This is w hy right temporarily defeated is stronger than evil triumphant. I believe that even amid today's motor bursts and whining bullets, there is still hope for a brighter tomorrow. I believe that wounded justice, lying prostrate on the blood-flowing streets of our nations, can be lifted from this dust of shame to reign supreme among the children of men. I have the audacity to believe that peoples everywhere can have three meals a day for their bodies, education and culture for their minds, and dignity, equality and freedom for their spirits. I believe that what self-centered men have torn down men other-centered can build up. I still believe that one day mankind will bow before the altars of God and be crowned triumphant over war and bloodshed, and nonviolent redemptive good will proclaimed the rule of the land. "And the lion and the lamb shall lie down together and every man s hall sit under his own vine and fig tree and none shall be afraid." I still believe that We Shall overcome!This faith can give us courage to face the uncertainties of the future. It will give our tired feet new strength as we continue our forward stride toward the city of freedom. When our days become dreary with low-hovering clouds and our nights become darker than a thousand midnights, we will know that we are living in the creative turmoil of a genuine civilization struggling to be born.Today I come to Oslo as a trustee, inspired and with renewed dedication to humanity. I accept this prize on behalf of all men who love peace and brotherhood. I say I come as a trustee, for in the depths of my hear! I am aware that this prize is much more than an honor to me personally.Every time I take a flight, I am always mindful of the many people who make a successful journey possible - the known pilots and the unknown ground crew.So you honor the dedicated pilots of our struggle who have sat at the controls as the freedom movement soared into orbit. Y ou honor, once again, Chief Lutuli of South Africa, whose struggles with and for his people, are still met with the most brutal expression of man's inhumanity to man. Y ou honor the ground crew without whose labor and sacrifices the jet flights to freedom could never have left the earth. Most of these people will never make the headline and their names will not appear in Who's Who. Y et when years have rolled past and when the blazing light of truth is focused on this marvelous age in which we live - men and women will know and children will be taught that we have a finer land, a better people, a more noble civilization - because these humble children of God were willing to suffer for righteousness sake.I think Alfred Nobel would know what I mean when I say that I accept this award in the spirit of a curator of some precious heirloom which he holds in trust for its true owners - all those to whom beauty is truth and truth beauty - and in whose eyes the beauty of genuine brotherhood and peace is more precious than diamonds or silver or gold。

Morrison, Nobel Prize Lecture

Morrison, Nobel Prize Lecture

Nobel LectureNobel Lecture December 7, 1993"Once upon a time there was an old woman. Blind but wise." Or was it an old man? A guru, perhaps. Or a griot soothing restless children. I have heard this story, or one exactly like it, in the lore of several cultures."Once upon a time there was an old woman. Blind. Wise."In the version I know the woman is the daughter of slaves, black, American, and lives alone in a small house outside of town. Her reputation for wisdom is without peer and without question. Among her people she is both the law and its transgression. The honor she is paid and the awe in which she is held reach beyond her neighborhood to places far away; to the city where the intelligenceof rural prophets is the source of much amusement.One day the woman is visited by some young people who seem to be bent on disproving her clairvoyance and showing her up for the fraud they believe she is. Their plan is simple: they enter her house and ask the one question the answer to which rides solely on her difference from them, a difference they regard as a profound disability: her blindness. They stand before her, and one of them says, "Old woman, I hold in my hand a bird. Tell me whether it is living or dead."She does not answer, and the question is repeated. "Is the bird I am holding living or dead?"Still she doesn't answer. She is blind and cannot see her visitors, let alone what is in their hands. She does not know their color, gender or homeland. She only knows their motive.The old woman's silence is so long, the young people have trouble holding their laughter.Finally she speaks and her voice is soft but stern. "I don't know", she says. "I don't know whether the bird you are holding is dead or alive, but what I do know is that it is in your hands. It is in your hands."Her answer can be taken to mean: if it is dead, you have either found it that way or you have killed it. If it is alive, you can still kill it. Whether it is to stayalive, it is your decision. Whatever the case, it is your responsibility.For parading their power and her helplessness, the young visitors are reprimanded, told they are responsible not only for the act of mockery but also for the small bundle of life sacrificed to achieve its aims. The blind woman shifts attention away from assertions of power to the instrument through which that power is exercised.Speculation on what (other than its own frail body) that bird-in-the-hand might signify has always been attractive to me, but especially so now thinking, as I have been, about the work I do that has brought me to this company. So I choose to read the bird as language and the woman as a practiced writer. She is worried about how the language she dreams in, given to her at birth, ishandled, put into service, even withheld from her for certain nefarious purposes. Being a writer she thinks of language partly as a system, partly as a living thing over which one has control, but mostly as agency - as an act with consequences. So the question the children put to her: "Is it living or dead?" is not unreal because she thinks of language as susceptible to death, erasure; certainly imperiled and salvageable only by an effort of the will. She believes that if the bird in the hands of her visitors is dead the custodians are responsible for the corpse. For her a dead language is not only one no longer spoken or written, it is unyielding language content to admire its own paralysis. Like statist language, censored and censoring. Ruthless in its policing duties, it has no desire or purpose other than maintaining the free range of its own narcotic narcissism, its own exclusivity and dominance. However moribund, it is not without effect for it actively thwarts the intellect, stalls conscience,suppresses human potential. Unreceptive to interrogation, it cannot form or tolerate new ideas, shape other thoughts, tell another story, fill baffling silences. Official language smitheryed to sanction ignorance and preserve privilege is a suit of armor polished to shocking glitter, a husk from which the knight departed long ago. Yet there it is: dumb, predatory, sentimental. Exciting reverence in schoolchildren, providing shelter for despots, summoning false memories of stability, harmony among the public.She is convinced that when language dies, out of carelessness, disuse, indifference and absence of esteem, or killed by fiat, not only she herself, but all users and makers are accountable for its demise. In her country children have bitten their tongues off and use bullets instead to iterate the voice of speechlessness, of disabled and disabling language, of language adults haveabandoned altogether as a device for grappling with meaning, providing guidance, or expressing love. But she knows tongue-suicide is not only the choice of children. It is common among the infantile heads of state and power merchants whose evacuated language leaves them with no access to what is left of their human instincts for they speak only to those who obey, or in order to force obedience.The systematic looting of language can be recognized by the tendency of its users to forgo its nuanced, complex, mid-wifery properties for menace and subjugation. Oppressive language does more than represent violence; it is violence; does more than represent the limits of knowledge; it limits knowledge. Whether it is obscuring state language or the faux-language of mindless media; whether it is the proud but calcified language of the academyor the commodity driven language of science; whether it is the malign language of law-without-ethics, or language designed for the estrangement of minorities, hiding its racist plunder in its literary cheek - it must be rejected, altered and exposed. It is the language that drinks blood, laps vulnerabilities, tucks its fascist boots under crinolines of respectability and patriotism as it moves relentlessly toward the bottom line and the bottomed-out mind. Sexist language, racist language, theistic language - all are typical of the policing languages of mastery, and cannot, do not permit new knowledge or encourage the mutual exchange of ideas.The old woman is keenly aware that no intellectual mercenary, nor insatiable dictator, no paid-for politician or demagogue; no counterfeit journalist would be persuaded by her thoughts. There is and will be rousing language to keepcitizens armed and arming; slaughtered and slaughtering in the malls, courthouses, post offices, playgrounds, bedrooms and boulevards; stirring, memorializing language to mask the pity and waste of needless death. There will be more diplomatic language to countenance rape, torture, assassination. There is and will be more seductive, mutant language designed to throttle women, to pack their throats like paté-producing geese with their own unsayable, transgressive words; there will be more of the language of surveillance disguised as research; of politics and history calculated to render the suffering of millions mute; language glamorized to thrill the dissatisfied and bereft into assaulting their neighbors; arrogant pseudo-empirical language crafted to lock creative people into cages of inferiority and hopelessness.Underneath the eloquence, the glamor, the scholarly associations, however stirring or seductive, the heart of such language is languishing, or perhaps not beating at all - if the bird is already dead.She has thought about what could have been the intellectual history of any discipline if it had not insisted upon, or been forced into, the waste of time and life that rationalizations for and representations of dominance required - lethal discourses of exclusion blocking access to cognition for both the excluder and the excluded.The conventional wisdom of the Tower of Babel story is that the collapse was a misfortune. That it was the distraction, or the weight of many languages that precipitated the tower's failed architecture. That one monolithic languagewould have expedited the building and heaven would have been reached. Whose heaven, she wonders? And what kind? Perhaps the achievement of Paradise was premature, a little hasty if no one could take the time to understand other languages, other views, other narratives period. Had they, the heaven they imagined might have been found at their feet. Complicated, demanding, yes, but a view of heaven as life; not heaven as post-life.She would not want to leave her young visitors with the impression that language should be forced to stay alive merely to be. The vitality of language lies in its ability to limn the actual, imagined and possible lives of its speakers, readers, writers. Although its poise is sometimes in displacing experience it is not a substitute for it. It arcs toward the place where meaning may lie. When a President of the United States thought about the graveyard his country hadbecome, and said, "The world will little note nor long remember what we say here. But it will never forget what they did here," his simple words are exhilarating in their life-sustaining properties because they refused to encapsulate the reality of 600, 000 dead men in a cataclysmic race war. Refusing to monumentalize, disdaining the "final word", the precise "summing up", acknowledging their "poor power to add or detract", his words signal deference to the uncapturability of the life it mourns. It is the deference that moves her, that recognition that language can never live up to life once and for all. Nor should it. Language can never "pin down" slavery, genocide, war. Nor should it yearn for the arrogance to be able to do so. Its force, its felicity is in its reach toward the ineffable.Be it grand or slender, burrowing, blasting, or refusing to sanctify; whether itlaughs out loud or is a cry without an alphabet, the choice word, the chosen silence, unmolested language surges toward knowledge, not its destruction. But who does not know of literature banned because it is interrogative; discredited because it is critical; erased because alternate? And how many are outraged by the thought of a self-ravaged tongue?Word-work is sublime, she thinks, because it is generative; it makes meaning that secures our difference, our human difference - the way in which we are like no other life.We die. That may be the meaning of life. But we do language. That may be the measure of our lives."Once upon a time, ..." visitors ask an old woman a question. Who are they, these children? What did they make of that encounter? What did they hear in those final words: "The bird is in your hands"? A sentence that gestures towards possibility or one that drops a latch? Perhaps what the children heard was "It's not my problem. I am old, female, black, blind. What wisdom I have now is in knowing I cannot help you. The future of language is yours."They stand there. Suppose nothing was in their hands? Suppose the visit was only a ruse, a trick to get to be spoken to, taken seriously as they have not been before? A chance to interrupt, to violate the adult world, its miasma of discourse about them, for them, but never to them? Urgent questions are at stake, including the one they have asked: "Is the bird we hold living or dead?" Perhaps the question meant: "Could someone tell us what is life? What isdeath?" No trick at all; no silliness. A straightforward question worthy of the attention of a wise one. An old one. And if the old and wise who have lived life and faced death cannot describe either, who can?But she does not; she keeps her secret; her good opinion of herself; her gnomic pronouncements; her art without commitment. She keeps her distance, enforces it and retreats into the singularity of isolation, in sophisticated, privileged space.Nothing, no word follows her declaration of transfer. That silence is deep, deeper than the meaning available in the words she has spoken. It shivers, this silence, and the children, annoyed, fill it with language invented on the spot."Is there no speech," they ask her, "no words you can give us that helps us break through your dossier of failures? Through the education you have just given us that is no education at all because we are paying close attention to what you have done as well as to what you have said? To the barrier you have erected between generosity and wisdom?"We have no bird in our hands, living or dead. We have only you and our important question. Is the nothing in our hands something you could not bear to contemplate, to even guess? Don't you remember being young when language was magic without meaning? When what you could say, could not mean? When the invisible was what imagination strove to see? When questions and demands for answers burned so brightly you trembled with furyat not knowing?"Do we have to begin consciousness with a battle heroines and heroes like you have already fought and lost leaving us with nothing in our hands except what you have imagined is there? Your answer is artful, but its artfulness embarrasses us and ought to embarrass you. Your answer is indecent in its self-congratulation. A made-for-television script that makes no sense if there is nothing in our hands."Why didn't you reach out, touch us with your soft fingers, delay the sound bite, the lesson, until you knew who we were? Did you so despise our trick, our modus operandi you could not see that we were baffled about how to get your attention? We are young. Unripe. We have heard all our short lives that wehave to be responsible. What could that possibly mean in the catastrophe this world has become; where, as a poet said, "nothing needs to be exposed since it is already barefaced." Our inheritance is an affront. You want us to have your old, blank eyes and see only cruelty and mediocrity. Do you think we are stupid enough to perjure ourselves again and again with the fiction of nationhood? How dare you talk to us of duty when we stand waist deep in the toxin of your past?"You trivialize us and trivialize the bird that is not in our hands. Is there no context for our lives? No song, no literature, no poem full of vitamins, no history connected to experience that you can pass along to help us start strong? You are an adult. The old one, the wise one. Stop thinking about saving your face. Think of our lives and tell us your particularized world. Make up a story.Narrative is radical, creating us at the very moment it is being created. We will not blame you if your reach exceeds your grasp; if love so ignites your words they go down in flames and nothing is left but their scald. Or if, with the reticence of a surgeon's hands, your words suture only the places where blood might flow. We know you can never do it properly - once and for all. Passion is never enough; neither is skill. But try. For our sake and yours forget your name in the street; tell us what the world has been to you in the dark places and in the light. Don't tell us what to believe, what to fear. Show us belief s wide skirt and the stitch that unravels fear's caul. You, old woman, blessed with blindness, can speak the language that tells us what only language can: how to see without pictures. Language alone protects us from the scariness of things with no names. Language alone is meditation."Tell us what it is to be a woman so that we may know what it is to be a man. What moves at the margin. What it is to have no home in this place. To be set adrift from the one you knew. What it is to live at the edge of towns that cannot bear your company."Tell us about ships turned away from shorelines at Easter, placenta in a field. Tell us about a wagonload of slaves, how they sang so softly their breath was indistinguishable from the falling snow. How they knew from the hunch of the nearest shoulder that the next stop would be their last. How, with hands prayered in their sex, they thought of heat, then sun. Lifting their faces as though is was there for the taking. Turning as though there for the taking. They stop at an inn. The driver and his mate go in with the lamp leaving them humming in the dark. The horse's void steams into the snow beneath itshooves and its hiss and melt are the envy of the freezing slaves."The inn door opens: a girl and a boy step away from its light. They climb into the wagon bed. The boy will have a gun in three years, but now he carries a lamp and a jug of warm cider. They pass it from mouth to mouth. The girl offers bread, pieces of meat and something more: a glance into the eyes of the one she serves. One helping for each man, two for each woman. And a look. They look back. The next stop will be their last. But not this one. This one is warmed."It's quiet again when the children finish speaking, until the woman breaks into the silence."Finally", she says, "I trust you now. I trust you with the bird that is not in your hands because you have truly caught it. Look. How lovely it is, this thing we have done - together."From Nobel Lectures, Literature 1991-1995, Editor Sture Allén, World Scientific Publishing Co., Singapore, 1997。

举办读书活动英语作文篇1As is well known,books teach us to learn life,truth,science and many other useful things.They increase our knowledge,broaden our minds and strengthen our character.In other words,they are our good teachers and wise friends.This is the reason why our parents always encourage us to read more books.Reading is a good thing,but we must pay great attention to the choice of books.It is true that we can derive benefits from good books.However,bad books will do us more harm than good.举办读书活动英语作文篇2The great writer gorky once said: "books are the ladder of human progress." "He spoke such a truth: actually the human to hard climbing, climbing a ladder of books. The books are made of ladder above, is a resplendent and magnificent palace of knowledge, therefore, we must try to climb, to learn from.Human knowledge to create wealth, as the vast ocean, extensive and profound. People often think of elementary school, middle school and university studies described as the "everybody" on climbing, in the "university" swim in. So, we should read more books and books to purify the mind, in thebook knowledge to enrich themselves.In our life, if always too passively reading, tend to be less than the pleasure of reading. With a scholarly paper, open a little tenderness, and then quietly looked at the text as time moves slip from your eyes... At this time, you will feel that reading is a matter of how to make people happy! Reading is a kind of mood, the elegant comfortable is the best psychological reagent. Go to the reading, you will have more found.Read more books, read good books.

Read to make us happy! Reading let us have more laughter!Among them, I most like to watch "Madame Curie". Madame Curie is like us, since the childhood like intimate contact with nature, Copernicus was her model. Selfless great simplicity, humility, her character, persistent, hard work, perseverance, indomitable spirit, she found two elements, polonium and radium, she won two Nobel prizes. Who can imagine, she is the "mother", radium gave great contribution to the wealth to the world, he even do research, could not afford to 1 gram of radium. As a great woman, she won the sympathy of the people of theworld, support and respect.Read the "Madame Curie", I think I should learn from her, learning her not to difficultly lowers the head, she determined the indomitable spirit of hard. I'm going to study hard, grow up to do a scientist like her.Let us together, can read, read good books, good books!举办读书活动英语作文篇4This afternoon, during the composition class, the teacher showed some diary of our classmates, and then accumulated some materials, so we began to read the secret garden.The teacher first designated the content to read, and clearly required: after we are familiar with the content, the role read in the group. Find partners and determine the task of everyone.After the teacher was finished, we quickly looked through the content we wanted to read, and we began to find our partners. I chose to set up with Liu Yuxi, because I think Liu Yu would be able to cooperate with me. Then we split the role —— I played the Marie group, and Liu Yuxi acted as master Colin. The beginning, found no narration, I call the teacher: “ we have no narrator ah, or we just read it. ” the teacher said, "“ let Teng Wenxi read it. You can read it easily." ” Teng Wenxi agreed, too. That's the way we're three.After we carefully practiced it several times, Wang Xinfei's group raised his hands to show it. The teacher asked us to be a civilized audience. We appreciate the Wang Xinfei group after the show, then the Qin Jiaqi group exhibition. At this time, the teacher asked us to summarize the two groups of performances. We speak very enthusiastically, the students do not talk much of the place, the teacher has affirmed their advantages.举办读书活动英语作文篇5April 23rd is the world reading day. There are more than 100 countries and regions all over the world to participate in this activity, and reading day has become a major concern of the world. Every year in April 23rd, every country's Reading Festival has become a joyous festival of reading and propaganda activities.On the day of reading, I also saw a number of media reports. At the same time, I also saw a group of surprising data, in China, 80% of the people do not know about the reading day, which makes me very feeling."Reading should be the most beautiful gesture." I was impressed by a classic quote by aunt Huang Beijia when he came to the school to open a lecture. Reading provides us with a vast expanse of heaven and earth. We can learn about history, life and nature in the course of reading. Reading can enrich our life, purify our minds, and promote our growth and maturity.A famous American scholar Tuchman's discussion about reading very vivid and incisive, he said: "the book is the transmission of civilization, no book, history will silence, literature became mute, science became a cripple, thought and exploration will come to a halt." Yes, books record the history of the development of human civilization. Human civilization has already passed through books, from generation to generation to today. China has been a great advocate of reading since ancient times. As we all know, Wuxi has a famous Donglin Academy antithetical couplet, on the "wind rain reading sound ear"; Anhui Hongcun Chengzhi hall also has a pair of antithetical couplet, couplet is "the first thing is to read."It is hoped that the whole society can enhance the consciousness of reading and make reading a need for everyonefrom the heart.举办读书活动英语作文篇6There is no denying that people can get a lot benefits from reading classics. On the one hand, it is a good way for readers to broaden their horizon and increase their knowledge in many aspects. For instance, they can learn the society characters by reading classic literature novels about history or culture. On the other hand, it also provides a chance for them to enhance their aesthetic taste in that most of classics has a very beautiful or unique language style and arts, which gives readers more enjoyment and interest.However, nowadays a large number of people, especially the young, are unwilling to or cannot spend their times in reading classics. There are some reasons accounting for the phenomenon and I would like to state two of them. For one thing, people are distracted by other things increasingly, which can give their more joy and fun and have no requirement in thinking, such as all kinds of entertainment activities. For another, some people think that it is no use of reading classics because these classics are outdated and useless to our society and lives.In my opinion, it is wrong to consider classics as an outdated matter because it still has many important functions and influence on our society and our lives. Classics are a kind of treasure in a nation. Therefore, we should give enough attention to them. And I advocate that all of us should try our best to read some of them.举办读书活动英语作文篇7Is now a knowledge society, if you want to get rich knowledge, the first is reading a book.Reading is the foundation of all kinds of learning. Ineverything we do, most can free our minds, so we should form the good habit of reading.I like to read books. As the saying goes: "read volumes, such as writing god." If we form the habit of reading, don't worry for not write a good composition.I like to read books. I gained a lot of knowledge, by reading, enlighten the wisdom, at the same time, can also open to the outside world, towards the future, to the Windows of the unknown world, made me know the famous ancient and modern, Chinese and foreign scientists, their story has been encouraged me to strive forward, made me even more motivated to learn.I like to read books. When reading a good book, like talking with a mentor, as if listening to their teacher.April 23 is world reading day. More and more countries joined celebrate this holiday, the day into joy reading festival. China's revitalization and strong, is start from reading. The classmates, let us now begin to form the good habit of reading! 举办读书活动英语作文篇8"Reading break rolls, such as writing, reading books, travelling"... When I was little, I vaguely remember my father told me that a lot of such things. Slowly grow up, I didn't know about the wisdom of reading whatever has a lot of ancient and modern, Chinese and foreign, and let's accumulated knowledge through books, find a lot of fun.Read the five thousand years I know briefly the development course of our country for thousands of years, know the origin of some of China's ancient legend; Know the yan emperor, the yellow emperor; Know why we call ourselves Chinese people... Read the "water margin", I know that treacherous court official in power, corrupt officials of the northern song dynasty, onehundred and eight men successively JuYi beam mountain, pull up the banner of "for good" Robin Hood, often hurt loyalist scenes such as living social and historical picture.When I finished reading "there is a feeling called heartache, I deeply realize the own-his umbilical affection is the family in the world, the world needs to give up a lot of things, the parents for their children, the children to the parents' love is forever is unable to give up.Gorky once said: "books are the ladder of human progress" we can get a lot of information and knowledge from the book, many of the letters are like that. We can see many in the past or in the book of modern mystery, in order to solve these mysteries, we will study hard, hard, after be brought up to dig these secrets; By reading the newspaper, we can see now the latest things, also can see what is a good man, what's bad, it's good for our judgement. If we look at many reference books, then we will have a lot of knowledge and the accumulation of vocabulary, this can let us become a Renaissance man in the future.This book is the only thing the undead is hill said, if we study, it is no good.

I have read many extra-curricular books from childhood to the present, a "Yang Hongying fairy tale"? "The first grade smallmelon"? And ultimately Sun Youjun's grandfather got up "and" pig grunt adventures "small cloth etc..Sob snoring is a pig famous Chinese children's literature history, it is not a ordinary pig, you don't see it, it has undergone many things. For example, the little pig asked his mother to celebrate her birthday. She wanted to earn some money for her mother to buy her birthday gift on her own efforts. Unfortunately, the fox's shopkeeper didn't speak well, and clearly said that he had given him a big cake and turned into a big egg.Also, sob snoring was the wolf away, it thought it was in the play on the swing, the wolf wanted to sob in three snoring his stomach, then got up snoring without fear, but with their own wisdom, the wolf away, cleverly escaped the wolf the palm of the hand. Later sob snore do not remember hatred, three children risked his life to save the wolf, the wolf was snoring to sob the doings touched, never do bad things, and finally as a teacher in the countryside. From this story, I understand that we would like to sob the snoring learning, to be a filial helpful child?.举办读书活动英语作文篇10We've done this part of the &mdash very seriously; — Marie and Colin quarreled. The teacher also summed up: “ do you think the third groups perform best? ” although some of the students were dissatisfied with us, we were still happy, so we went on and practised several times. At this time, the teacher let the students stop, named to me and Liu Yu Xi to show up, the cancellation of the narration, direct dialogue, so the atmosphere will be more strong.Liu Yuxi and I started “ the quarrel ” When I read Mari e's temper, I was as loud as a real quarrel, trying to feel Marie's mood and imitating the tone of the quarrel. Liu Yuxi also read Colin fromangry to injustice. Both of us were in special play.After the performance, the teacher said I had a large group of performances. Liu Yuxi also had Colin's pain when he was sick. We expressed the feelings of the characters in the book very well by understanding the content. We are very happy to hear the teacher's praise.I wish I could have a chance to take part in this kind of reading.举办读书活动英语作文篇11A lot of people praise the benefits of reading. When I was growing up, enjoy reading, is the greatest happiness.Listen to mama said, when I was only a few months old, whenever I cry, the mother is telling a story to me, I immediately quiet down. Two birthday that day, my mother gave me the first book, the Oriental youth ". When I use puerile hand opened the book and the first page and will be attracted by colorful illustrations in the book. Every day I was turned over and over again, never tireless.Gradually go to school, I know the pinyin, getting to know some words, so the mother doing the housework is always let me read a small story to her, also said that if I don't read, she haven't the strength to do things, so I believe her words. Read a story, if don't know the words and do not understand the word, I would have to ask my mom, mom will answer for me. Through the process of "reading" and "q", not only did I know a lot of words, grow a lot of knowledge, also increasingly feel the pleasure of reading. In this way, gradually, I fell in love with reading. Mother use special methods to me into the realm of words, the world of books.There are a lot of species I like reading books, never confinedto a particular category. In reading, I also know a lot of sense. In "if give me three days light", Helen Keller lost sight and hearing in her stubborn will tell us, physical disability and have no what, really terrible is the heart of disability.A person, even if his body is disabled, as long as he has a heart healthy, optimistic, or full of hope in the future. It's like Helen Keller said: "although my body is not free, but my heart is free. So as long as we have fortitude character, can overcome the setbacks in life."举办读书活动英语作文篇12People often say that gold and silver are the most valuable things in the world.ButI don't think so. In my opinion, to read books is more valuable than anything else.The old saying "To open a book is always helpful" clearly tells us how good it is to read a book.Books are our friends. They introduce us different kinds of knowledge. They lead us down the road to success.Books are our teachers. They teach us troth, science, literature, and philosophy of life. Besides, they increase our knowledge, enlarge our experience,strengthen our character and do many other things which we can not do without them.Books tell us what is good and what is evil. And only books can tell the good from the bad.Therefore to read more books is the best policy for our young students.。

Nobel LectureToni Morrison(December7,1933)"Once upon a time there was an old woman. Blind but wise." Or was it an old man? A guru, perhaps. Or a griot soothing restless children. I have heard this story, or one exactly like it, in the lore of several cultures."Once upon a time there was an old woman. Blind. Wise."In the version I know the woman is the daughter of slaves, black, American, and lives alone in a small house outside of town. Her reputation for wisdom is without peer and without question.Among her people she is both the law and its transgression. The honor she is paid and the awe in which she is held reach beyond her neighborhood to places far away; to the city where the intelligence of rural prophets is the source of much amusement.One day the woman is visited by some young people who seem to be bent on disproving her clairvoyance and showing her up for the fraud they believe she is. Their plan is simple: they enter her house and ask the one question the answer to which rides solely on her difference from them, a difference they regard as a profound disability: her blindness. They stand before her, and one of them says,"Old woman, I hold in my hand a bird. Tell me whether it is living or dead."She does not answer, and the question is repeated. "Is the bird I am holding living or dead?"Still she does not answer. She is blind and cannot see her visitors, let alone what is in their hands. She does not know their color, gender or homeland. She only knows their motive.The old woman's silence is so long, the young people have trouble holding their laughter.Finally she speaks, and her voice is soft but stern. "I don't know," she says. "I don't know whether the bird you are holding is dead or alive, but what I do know is that it is in your hands. It is in your hands."Her answer can be taken to mean: if it is dead, you have either found it that way or you have killed it. If it is alive, you can still kill it. Whether it is to stay alive,it is your decision. Whatever the case, it is your responsibility.For parading their power and her helplessness, the young visitors are reprimanded, told they are responsible not only for the act of mockery but also for the small bundleof life sacrificed to achieve its aims. The blind woman shifts attention away from assertions of power to the instrument through which that power is exercised.Speculation on what (other than its own frail body) that bird-in-the-hand might signify has always been attractive to me, but especially so now thinking, as I have been, about the work I do that has brought me to this company. So I choose to read the bird as language and the woman as a practiced writer.She is worried about how the language she dreams in, given to her at birth, is handled, put into service, even withheld from her for certain nefarious purposes. Being a writer, she thinks of language partly as a system, partly as a living thing over which one has control, but mostly as agency—as an act with consequences. So the question the children put to her, "Is it living or dead?," is not unreal because she thinks of language as susceptible to death, erasure; certainly imperiled and salvageable only by an effort of the will. She believes that if the bird in the hands of her visitors is dead, the custodians are responsible for the corpse. For her a dead language is not only one no longer spoken or written, it is unyielding language content to admire its own paralysis. Like statist language, censored and censoring. Ruthless in its policing duties, it has no desire or purpose other than maintaining the free range of its own narcotic narcissism, its own exclusivity and dominance. However moribund, it is not without effect, for it actively thwarts the intellect, stalls conscience, suppresses human potential. Unreceptive to interrogation, it cannot form or tolerate new ideas, shape other thoughts, tell another story, fill baffling silences. Official language smitheryed to sanction ignorance and preserve privilege is a suit of armor polished to shocking glitter, a husk from which the knight departed long ago. Yet there it is; dumb, predatory, sentimental. Exciting reverence in schoolchildren, providing shelter for despots, summoning false memories of stability, harmony among the public.She is convinced that when language dies, out of carelessness, disuse, indifference and absence of esteem, or killed by fiat, not only she herself, but all users and makers are accountable for its demise. In her country children have bitten their tongues off and use bullets instead to iterate the voice of speechlessness, of disabled and disabling language, of language adults have abandoned altogether as a device for grappling with meaning, providing guidance, or expressing love. But she knows tongue-suicide is not only the choice of children. It is common among the infantile heads of state and power merchants whose evacuated language leaves them with no access to what is left of their human instincts for they speak only to those who obey, or in order to force obedience.The systematic looting of language can be recognized by the tendency of its users to forgo its nuanced, complex, mid-wifery properties for menace and subjugation. Oppressive language does more than represent violence; it is violence; does more than represent the limits of knowledge; it limits knowledge. Whether it is obscuring state language or the faux-language of mindless media; whether it is the proud hut calcified language of the academy or the commodity driven language of science; whether it isthe malign language of law-without-ethics,or language designed for the estrangement of minorities, hiding its racist plunder in its literary cheek –it must be rejected, altered and exposed. It is the language that drinks blood, laps vulnerabilities, tucks its fascist boots under crinolines of respectability and patriotism as it moves relentlessly toward the bottom line and the bottomed-out mind. Sexist language, racist language, theistic language – all are typical of the policing languages of mastery, and cannot, do not permit new knowledge or encourage the mutual exchange of ideas.The old woman is keenly aware that no intellectual mercenary, nor insatiable dictator, no paid-for politician or demagogue, no counterfeit journalist would be persuaded by her thoughts. There is and will be rousing language to keep citizens armed and arming; slaughtered and slaughtering in the malls, courthouses, post offices, playgrounds, bedrooms and boulevards; stirring, memorializing language to mask the pity and waste of needless death. There will be more diplomatic language to countenance rape, torture, assassination. There is and will be more seductive, mutant language designed to throttle women, to pack their throats like pâté-producing geese with their own unsayable, transgressive words; there will be more of the language of surveillance disguised as research; of politics and history calculated to render the suffering of millions mute; language glamorized to thrill the dissatisfied and bereft into assaulting their neighbors; arrogant pseudo-empirical language crafted to lock creative people into cages of inferiority and hopelessness.Underneath the eloquence, the glamor, the scholarly associations, however stirring or seductive, the heart of such language is languishing, or perhaps not beating at all – if the bird is already dead.She has thought about what could have been the intellectual history of any discipline if it had not insisted upon, or been forced into, the waste of time and life that rationalizations for and representations of dominance required – lethal discourses of exclusion blocking access to cognition for both the excluder and the excluded.The conventional wisdom of the Tower of Babel story is that the collapse was a misfortune. That it was the distraction, or the weight of many languages that precipitated the tower's failed architecture. That one monolithic language would have expedited the building and heaven would have been reached. Whose heaven, she wonders? And what kind? Perhaps the achievement of Paradise was premature, a little hasty if no one could take the time to understand other languages, other views, other narratives period. Had they, the heaven they imagined might have been found at their feet. Complicated, demanding, yes, but a view of heaven as life; not heaven as post-life. She would not want to leave her young visitors with the impression that language should be forced to stay alive merely to be. The vitality of language lies in its ability to limn the actual, imagined and possible lives of its speakers, readers, writers. Although its poise is sometimes in displacing experience it is not a substitute for it. It arcs toward the place where meaning may lie. When a President of the UnitedStates thought about the graveyard his country had become, and said, "The world will little note nor long remember what we say here. But it will never forget what they did here," his simple words were exhilarating in their life-sustaining properties because they refused to encapsulate the reality of 600,000 dead men in a cataclysmic race war. Refusing to monumentalize, disdaining the "final word," the precise "summing up," acknowledging their "poor power to add or detract," his words signal deference to the uncapturability of the life it mourns. It is the deference that moves her, that recognition that language can never live up to life once and for all. Nor should it. Language can never "pin down" slavery, genocide, war. Nor should it yearn for the arrogance to be able to do so. Its force, its felicity is in its reach toward the ineffable.Be it grand or slender, burrowing, blasting or refusing to sanctify; whether it laughs out loud or is a cry without an alphabet, the choice word, the chosen silence, unmolested language surges toward knowledge, not its destruction. But who does not know of literature banned because it is interrogative; discredited because it is critical; erased because alternate? And how many are outraged by the thought of a self-ravaged tongue?Word-work is sublime, she thinks, because it is generative; it makes meaning that secures our difference, our human difference – the way in which we are like no other life.We die. That may be the meaning of life. But we do language. That may be the measure of our lives."Once upon a time . . ." Visitors ask an old woman a question. Who are they, these children? What did they make of that encounter? What did they hear in those final words: "The bird is in your hands"? A sentence that gestures toward possibility or one that drops a latch? Perhaps what the children heard was, "It is not my problem. I am old, female, black, blind. What wisdom I have now is in knowing I cannot help you. The future of language is yours."They stand there. Suppose nothing was in their hands? Suppose the visit was only a ruse, a trick to get to be spoken to, taken seriously as they have not been before? A chance to interrupt, to violate the adult world, its miasma of discourse about them.for them,but never to them? Urgent questions are at stake, including the one they have asked: "Is the bird we hold living or dead?" Perhaps the question meant: "Could someone tell us what is life? What is death?" No trick at all; no silliness. A straightforward question worthy of the attention of a wise one. An old one. And if the old and wise who have lived life and faced death cannot describe either, who can? But she does not; she keeps her secret; her good opinion of herself; her gnomic pronouncements; her art without commitment. She keeps her distance, enforces it andretreats into the singularity of isolation, in sophisticated, privileged space.Nothing, no word follows her declaration of transfer. That silence is deep, deeper than the meaning available in the words she has spoken. It shivers, this silence, and the children annoyed, fill it with language invented on the spot."Is there no speech," they ask her, "no words you can give us that helps us break through your dossier of failures? Through the education you have just given us that is no education at all because we are paying close attention to what you have done as well as to what you have said?To the barrier you have erected between generosity and wisdom?"We have no bird in our hands, living or dead. We have only you and our important question. Is the nothing in our hands something you could not bear to contemplate, to even guess? Don't you remember being young when language was magic without meaning? When what you could say, could not mean? When the invisible was what imagination strove to see? When questions and demands for answers burned so brightly you trembled with fury at not knowing?"Do we have to begin consciousness with a battle heroines and heroes like you have already fought and lost leaving us with nothing in our hands except what you have imagined is there? Your answer is artful, but its artfulness embarrasses us and ought to embarrass you. Your answer is indecent in its self-congratulation. A made-for-television script that makes no sense if there is nothing in our hands. "Why didn't you reach out, touch us with your soft fingers, delay the sound bite, the lesson, until you knew who we were? Did you so despise our trick, our modus operandi you could not see that we were baffled about how to get your attention? We are young. Unripe. We have heard all our short lives that we have to be responsible. What could that possibly mean in the catastrophe this world has become; where, as a poet said, "nothing needs to be exposed since it is already barefaced"? Our inheritance is an affront. You want us to have your old, blank eyes and see only cruelty and mediocrity. Do you think we are stupid enough to perjure ourselves again and again with the fiction of nationhood? How dare you talk to us of duty when we stand waist deep in the toxin of your past?"You trivialize us and trivialize the bird that is not in our hands. Is there no context for our lives? No song, no literature, no poem full of vitamins, no history connected to experience that you can pass along to help us start strong? You are an adult. The old one, the wise one. Stop thinking about saving your face. Think of our lives and tell us your particularized world. Make up a story. Narrative is radical, creating us at the very moment it is being created. We will not blame you if your reach exceeds your grasp; if love so ignites your words they go down in flames and nothing is left but their scald. Or if, with the reticence of a surgeon's hands, your words suture only the places whereblood might flow. We know you can never do it properly – once and for all. Passion is never enough; neither is skill. But try. For our sake and yours forget your name in the street; tell us what the world has been to you in the dark places and in the light. Don't tell us what to believe, what to fear. Show us belief's wide skirt and the stitch that unravels fear's caul. You, old woman, blessed with blindness, can speak the language that tells us what only language can: how to see without pictures. Language alone protects us from the scariness of things with no names. Language alone is meditation."Tell us what it is to be a woman so that we may know what it is to be a man. What moves at the margin. What it is to have no home in this place. To be set adrift from the one you knew. What it is to live at the edge of towns that cannot bear your company."Tell us about ships turned away from shorelines at Easter, placenta in a field. Tell us about a wagonload of slaves, how they sang so softly their breath was indistinguishable from the falling snow. How they knew from the hunch of the nearest shoulder that the next stop would be their last. How, with hands prayered in their sex, they thought of heat, then sun. Lifting their faces as though it was there for the taking. Turning as though there for the taking. They stop at an inn. The driver and his mate go in with the lamp leaving them humming in the dark. The horse's void steams into the snow beneath its hooves and its hiss and melt are the envy of the freezing slaves. "The inn door opens: a girl and a boy step away from its light. They climb into the wagon bed. The boy will have a gun in three years, but now he carries a lamp and a jug of warm cider. They pass it from mouth to mouth. The girl offers bread, pieces of meat and something more: a glance into the eyes of the one she serves. One helping for each man, two for each woman. And a look. They look back. The next stop will be their last. But not this one. This one is warmed."It's quiet again when the children finish speaking, until the woman breaks into the silence."Finally," she says. "I trust you now. I trust you with the bird that is not in your hands because you have truly caught it. Look. How lovely it is, this thing we have done –together."。
