旋转式水稻钵苗移栽机构的毕业设计
摘要水稻钵苗移栽是一种利用钵盘育秧的水稻移栽技术，是水稻种植过程中的重要环节。
水稻的钵盘育秧充分保留了秧苗生长的营养土质，植伤轻、返苗快，使作物提早成熟，且增产增收；移栽充分利用了光热资源，对水稻秧苗有气候的补偿作用，同时有使作物生育提早的综合效益，因此水稻的钵苗移栽可以产生非常可观的经济效益和社会效益。
但与其他国家和地区相比，我国水稻种植机械化程度较低，与国内水稻生产的其它环节相比，机械化程度也是最低的。
因此研究一种新的水稻钵苗移载机构，对水稻的机械化种植与高产高收具有非常重要的意义。
本文通过对国内外的水稻钵苗移栽机构进行对比分析，提出了一种高效率的水稻钵苗移栽机构为旋转式水稻钵苗移栽机构。
该水稻钵苗移栽机构由驱动部分与移栽臂两部分构成，其中驱动部分由非匀速间歇传动机构与非匀速传动机构串联组成，移栽臂用于完成机构的取秧、推秧。
本文的研究内容如下：1.根据水稻钵苗移栽的农艺特性与工作轨迹的要求，确定了以椭圆－不完全非圆齿轮行星轮系为传动机构的设计方案，该旋转式传动机构平稳性好、效率高。
2.分析了该水稻钵苗移栽机构的工作原理，并对机构进行运动学建模与传动特性分析。
3通过水稻钵苗移栽机构的辅助分析与优化软件，对该机构进行参数优化，最后得到一组较优的结构参数：a=23.069mm，k=0.994，α=291°，λ=6°，δ=29°，φ0=-39°，S=152mm.4.根据机构优化后的结构参数，在CAD2008软件中对水稻钵苗移栽机构进行整体的结构设计与各零部件的二维设计。
5.在ug8.0三维实体建模软件中完成各零部件的建模与机构的装配。
关键词：水稻钵苗移栽；行星系移栽机构；椭圆－不完全非圆齿轮；参数优化；设计；Parameter Optimization and Design of Rotary Rice Bowl Seedling Transplanting MechanismAbstractRice bowl seedling transplanting is a transplanting technology with bowl seedling ，which plays an important part in the process of rice cultivation. The nutrient soil is fully reserved with rice seedling through bowl seedling technology ，so it barely hurts seedlings and makes them grow and mature faster，furthermore，it increases rice production;Transplanting takes full advantage of the light and heat resources，which makes climate compensation to rice seedlings and shifts crop fertility to an earlier date，Therefore the rice bowl seedling transplanting can produce substantial economic and social benefits. However，compared with other countries and regions，the mechanization level of rice cultivation in China is relatively low，and the degree of mechanization is also the lowest compared to other domestic rice production processes.Therefore the study of a new rice bowl seedling transplanting mechanism has a very important significance in mechanized cultivation and high-yielding of rice .Through comparative analysis of rice bowl seedling transplanting mechanisms at home and abroad，this paper comes up with a new type of rice bowl seedling transplanting mechanism with which the transplanter can achieve high efficient transplanting—rice bowl seedling transplanting mechanism of planetary gear train with ellipse gears and incomplete non-circular gear. The rice bowl seedling transplanting mechanism includes two parts : drive part and transplanting arms ，the drive part consists of non-uniform intermittent transmission and non-uniform transmission mechanism，and the transplanting arms are used for the completion of fetching and pushing seedlings.This transplanting mechanism has applied for inventive patent (application number : 201210344077.1)and utility model pantent (patent number: ZL201220474441.1) is authorized.The main content of this paper is listed as bellow:1.According to the requirements of the agronomic characteristics and work trajectory of rice bowl seedling transplanting，invent the rice bowl seedlingtransplanting mechanism of planetary gear train with ellipse gears and incomplete non-circular gear，The rotary drive mechanism has a good stability and high efficiency.2.Analyze the work principle of the rice bowl seedling transplanting mechanism ，build kinematics model and analyze transmission characteristics of this mechanism.3.Through the software of aided analysis and optimization of rice bowl seedling transplanting mechanism，search a group of structure parameters: a = 23.069mm，k = 0.994，α = 291°，λ = 6 °，δ = 29 °，φ0 = -39 °，S = 152mm.4.According to the optimized structure parameters of the mechanism，design the overall structure and complete two-dimensional drawings of all parts in CAD2008.5.Establish the three-dimensional model of all parts of this rice bowl seedling transplanting mechanism and complete the assembly in ug8.0。

The slope is 0.5A/us. The frequency is 100Hz. Output overshoot is lower than ±5%.Protection requirementShort circuit protection: when outputting short circuit, the input power will lower and will not have any affect. After ending the short circuit, the system will recover automatically.Overcurrent protectionOCSET: within 110%-180% of maximum load (with rated voltage), when outputting overcurrent, the output will go to hiccup mode. After ending the overcurrent, the system will recover automatically.Configure RPLIDAR A3 Scan FrequencyThe motor speed control signal MOTOCTL can be configured directly via the USB adapter of RPLIDAR A3. Therefore, the RPLIDAR A3’s scan frequency can be modified by invoking the related functions in the SDK to configure the motor speed.Without the USB adapter, users can also control the speed by setting the PWM duty cycle of MOTOCTL. Please note that the PWM frequency is 20kHz. For more detailed parameter and index, please refer to the datasheet.Please refer to the RPLIDAR protocol and application note for more information and the SDK for the sample code on RPLIDAR scan frequency.SDK UsageSLAMTEC provides RPLIDAR SDK support on both Windows and Linux platform. And users can embed the SDK source code to other operational system or embedded system quickly. Please refer to the SDK document for more information.Pre-Heating for Best PerformanceThe scan core will be heating when start working. We recommend pre-heating RPLIDAR (Start the scan mode and the scan motor is rotating) for more than 2 minutes to get the best measurement accuracy.Ambient TemperatureRPLIDAR’s measurement resolution is sensitive to the ambient temperature. Improper use may even damage the sensor. Please avoid using RPLIDAR in extreme high temperature (>40 degree) and too low temperature (<-10 degree).Ambient LightCompared with RPLIDAR A2 series, RPLIDAR A3 performs better to resist ambient light interference, which supports it to work properly in outdoor environment.RPLIDAR A3 can work in two modes: enhanced mode and outdoor mode.Enhanced mode is designed for indoor environment. Typical indoor light (including situations without light) will not affect the performance of RPLIDAR. Strong light (such as high power laser) will harm the optical system of LIDAR, which should be avoided.During outdoor mode, RPLIDAR A3 can work normally to detect objects under direct ambient light. However, the ranging distance might be shorter under strong direct sunlight and it is still necessary to protect the optical system from direct sunlight.Image and Table IndexF IGURE 1-1I TEMS IN THE RPLIDAR D EVELOPMENT K IT (3)F IGURE 1-2T HE RPLIDAR (4)F IGURE 1-3RPLIDAR A DAPTER (4)F IGURE 2-1C ONNECT RPLIDAR A3 AND USB A DAPTER (5)F IGURE 2-2C ONNECT THE USB A DAPTER TO PC VIA M ICRO-USB C ABLE (5)F IGURE 2-3C HOOSE USB A DAPTER D RIVER FOR I NSTALLATION (6)F IGURE 2-4S TART P AGE OF USB A DAPTER D RIVER I NSTALLATION (6)F IGURE 2-5R ECOGNIZED S ERIAL P ORT N AME M ATCHED WITH THE USB A DAPTER (6)F IGURE 2-6R OBO S TUDIO L OGIN P AGE (7)F IGURE 2-7T HE L IDAR P LUGIN IN R OBO S TUDIO (8)F IGURE 2-8T HE S UPPORTED C OMMANDS OF RPLIDAR IN R OBO S TUDIO (8)F IGURE 2-9T HE S CAN O UTLINE BY RPLIDAR IN R OBO S TUDIO (9)F IGURE 2-10T HE M OTOR S PEED A DJUSTMENT D IALOGUE OF RPLIDAR IN R OBO S TUDIO (10)F IGURE 3-1RPLIDAR A3P INS (11)F IGURE 3-2RPLIDAR P IN D EFINITION AND S PECIFICATION (11)F IGURE 3-3RPLIDAR A3P INS R EFERENCE D ESIGN (12)F IGURE 3-4RPLIDAR P OWER A DAPTER I NPUT S PECIFICATION (12)F IGURE 3-5RPLIDAR P OWER A DAPTER O UTPUT S PECIFICATION (13)F IGURE 3-6RPLIDAR P OWER A DAPTER L INE/L OAD R EGULATION (13)。

Then, as you listen to the tape the first time, circle the words you hear.prime minister author painter politician World War I romantic fearless serious passionate World War IISecond ListeningRead the following questions first to prepare yourself to answer them to the best of your ability.2. What was the argument about? Which side do you believe?3. What do you know about Winston Churchill as British prime minister? What about his personality—do you have any impressions of him as a human being?Winston Churchill—His Other LifeMary SoamesMy father, Winston Churchill, began his love affair with painting in his 40s, amid disastrous circumstances. As First Lord of the Admiralty in 1915, he had been deeply involved in a campaign in the Dardanelles that could have shortened the course of a bloody world war. But when the mission failed, with great loss of life, Churchill paid the price, both publicly andprivately: He was removed from the Admiralty and lost his position of political influence.Overwhelmed by the disaster — "I thought he would die of grief," said his wife, Clementine — he retired with his family to Hoe Farm, a country retreat in Surrey. There, as Churchill later recalled, "The muse of painting came to my rescue!"One day when he was wandering in the garden, he chanced upon his sister-in-law sketching with watercolours. He watched her for a few minutes, then borrowed her brush and tried his hand — and the muse worked her magic. From that day forward, Winston was in love with painting.Delighted with anything that distracted Winston from the dark thoughts that overwhelmed him, Clementine rushed off to buy whatever paints and materials she could find. Watercolours, oil paints, paper, canvas —Hoe Farm was soon filled with everything a painter could want or need.Painting in oils turned out to be Winston's great love — but the first steps were strangely difficult. He contemplated the blank whiteness of his first canvas with unaccustomed nervousness. He later recalled:"Very hesitantly I selected a tube of blue paint, and with infinite precaution made a mark about as big as a bean on the snow-white field. At that moment I heard the sound of a motorcar in the drive and threw down my brush in a panic. I was even more alarmed when I saw who stepped from the car: the wife of Sir John Lavery, the celebrated painter who lived nearby."'Painting!' she declared. 'What fun. But what are you waiting for? Let me have the brush — the big one.' She plunged into the paints and before I knew it, she had swept several fierce strokes and slashes of blue on the absolutely terrified canvas. Anyonecould see it could not hit back. I hesitated no more. I seized the largest brush and fell upon my wretched victim with wild fury. I have never felt any fear of a canvas since."Lavery, who later tutored Churchill in his art, said of his unusual pupil's artistic abilities: "Had he chosen painting instead of politics, he would have been a great master with the brush."In painting, Churchill had discovered a companion with whom he was to walk for the greater part of his life. Painting would be his comfort when, in 1921, the death of his mother was followed two months later by the loss of his and Clementine's beloved three-year-old daughter, Marigold. Overcome by grief, Winston took refuge at the home of friends in Scotland — and in his painting. He wrote to Clementine: "I went out and painted a beautiful river in the afternoon light with red and golden hills in the background. Many loving thoughts.... Alas, I keep feeling the hurt of Marigold."Life and love and hope slowly revived. In September 1922 another child was born to Clementine and Winston: myself. In the same year, Winston bought Chartwell, the beloved home he was to paint in all its different aspects for the next 40 years.My father must have felt a glow of satisfaction when in the mid-1920s he won first prize in a prestigious amateur art exhibition held in London. Entries were anonymous, and some of the judges insisted that Winston's picture — one of his first of Chartwell — was the work of a professional, not an amateur, and should be disqualified. But in the end, they agreed to rely on the artist's honesty and were delighted when they learned that the picture had been painted by Churchill.Historians have called the decade after 1929, when Winston again fell from office, his barren years. Politically barren they mayhave been, as his lonely voice struggled to awaken Britain to the menace of Hitler, but artistically those years bore abundant fruit: of the 500-odd Churchill canvases in existence, roughly half date from 1930 to 1939.Painting remained a joy to Churchill to the end of his life. "Happy are the painters," he had written in his book Painting as a Pastime, "for they shall not be lonely. Light and colour, peace and hope, will keep them company to the end of the day." And so it was for my father.New Wordsamidprep.in the middle of, among 在…之中* disastrousa. extremely bad; terrible 灾难性的，糟透的lordn.

As a result, elective courses are available not only for excellent academic performers but also for students about the average level.Certainly, students have different reasons to choose their own electives. For some, practical skills are the essence of college education, and therefore, courses on computer science, marketing, and finance are highly preferred. However, others may hold the idea of liberal education and electives concerning literature, history, and philosophy are the most welcome.Take me as an example: being a disciple of free education, I stand for the notion that university is not a place for survival skills, but a palace of knowledge and critical reasoning. Although my major is chemistry, the electives I attend most frequently are English literature, an Introduction to Classic Music, and Different Schools of Western Painting. They really widen my horizon.

(20%)The Fantastic Spurt in TechnologyTo most people the term technology conjures up images of smoky steel mills or noisy machines. Perhaps the classic representation of technology is still the assembly line created by Henry Ford a century ago and made into social symbol by Charlie Chaplin in Modern Times. This symbol, however, has always been inadequate and misleading, for technology has always been more than factories and machines. The invention of the horse collar in the middle ages led to major changes in agricultural methods and was as much a technological advance as the invention of the Bessemer furnace centuries later. Moreover, technology includes techniques, or ways to do things, as well as the machines that may or may not be necessary to apply them. It includes ways to make chemical reactions occur, ways to breed fish, plant forests, light theaters, count votes or teach history.The old symbols of technology are even more misleading today, when the most advanced technological processes are carried out far from assembly lines or blast furnaces. Indeed, in electronics, in space technology, in most of the new industries, quiet and clean surroundings are characteristic --- even sometimes essential. And the assembly line --- the organization of large numbers of men to carry out simple repetitive functions --- is outdated. It is time for our symbols of technology to change --- to catch up with the quickening changes in technology itself.This acceleration is frequently dramatized by a brief account of the progress in transportation. It has been pointed out, for example, that in (6000 BC the fastest transportation available to man over long distances was the camel caravan, averaging eight miles per hour (mph). It was not until about 1600 BC when the chariot was invented that the maximum speed was raised to roughly twenty miles per hour.So impressive was this invention, so difficult was it to exceed this speed limit, that nearly 3,500 years later, when the first mail coach began operating in England in 1784, it averaged a mere ten mph. The first steam locomotive, introduced in 1825, could have a top speed of only thirteen mph and the great sailing ships of the time labored along at less than half that speed. It was probably not until the 1880’s that man, with the help of a more advanced stream locomotive, managed to reach a speed of one hundred mph. It took the human race millions of years to attain that record.It took only fifty-eight years, however, to go four times that fast, so that by1938 men in airplanes were traveling at better than 400 mph. It took a mere twenty-year flick of the time to double the limit again. And by the 1960’s rocket planes approached speeds of 4,000 mph. And men in space capsules were circling the earth at 18,000 mph.Whether we examine distances traveled, altitudes reached, or mineral mined, the same accelerative trend is obvious. The pattern, here and in a thousand other statistical series, is absolutely clear and unmistakable. Thousands of years go by, and then, in our own times, a sudden bursting of the limits, a fantastic spurt forward.The reason for this is that technology feeds on itself. Technology makes moretechnology possible, as we can see if we look for a moment at the process of innovation. Technological innovation consists of three stages, linked together into a self-reinforcing cycle. First, there is a creative, feasible idea. Second, its practical application. Third, its diffusion through society.The process is completed, the loop closed, when the diffusion of technology embodying the new idea, in turn, helps generate new creative ideas. Today there is evidence that the time between each of the steps in this cycle has been shortened.Thus it is not merely true, as frequently noted, that 90 percent of all the scientists who ever lived are now alive, and that new scientific discoveries are being made every day. These new ideas are put to work much more quickly than ever before. The time between the first and the second stage of the cycle --- between idea and application --- has be radically reduced. This is a striking difference between ourselves and our ancestors. It is not that we are more eager or less lazy than our ancestors, but we have, with passage of time, invented all sorts of social devices to hasten the process.But if it takes less time to bring a new idea to the marketplace, it also takes less time for it to sweep through the society. For example, the refrigerator was introduce in the United States before 1920, yet its peak production did not come until more than thirty years later. However, by 1950 --- in only a few years --- television had grown from a laboratory novelty to the biggest part of show business. So the internal between the second and third stages of the cycle --- between application and diffusion --- has likewise been cut, and the pace of diffusion is rising with astonishing speed.The stepped-up pace of invention, application and diffusion, in turn, accelerate the whole cycle still further. For new machines or techniques are not merely a product, but a source, of fresh creative ideas.Direction:Answer the following questions according to the information in the text.1.According to the text what images does technology conjure up tomost people?To most people the term technology conjures up images of smokysteel mills or noisy machines.2.What is the classic symbol of technology?the assembly line3.According to the author, what does technology mean?technology includes inventions, techniques, or ways to do things, aswell as the machines that may or may not be necessary to apply them.our symbols of technology --- to catch up with the quickeningchanges in technology itself.4.What are the three stages of technological innovation?Technological innovation consists of three stages, linked together intoa self-reinforcing cycle. First, there is a creative, feasible idea.Second, its practical application. Third, its diffusion through society.5.What is the striking difference between ourselves and our ancestors?The time between the first and the second stage of the cycle ---between idea and application --- has be radically reduced. This is astriking difference between ourselves and our ancestors.Part III: Translation (30%)Directions: Translate the following two passages from the text into Chinese.The reason for this is that technology feeds on itself.

得知自己考了第一名欣喜若狂的英语作文500字
全文分为作者个人简介和正文两个部分：作者个人简介：Hello everyone, I am an author dedicated to creating and sharing high-quality document templates. In this era of information overload, accurate and efficient communication has become especially important. I firmly believe that good communication can build bridges between people, playing an indispensable role in academia, career, and daily life. Therefore, I decided to invest my knowledge and skills into creating valuable documents to help people find inspiration and direction when needed.正文：得知自己考了第一名欣喜若狂的英语作文500字全文共3篇示例，供读者参考篇1I Couldn't Believe My Eyes When I Saw My Name at the Top!You know that feeling when you've been working so hard for something, putting in countless hours of effort and sacrifice, and it all comes down to one pivotal moment? That's exactly how Ifelt as I anxiously awaited the results of the annual academic decathlon. My heart was pounding, my palms were sweaty, and I could hardly breathe as the announcer took the stage."And now, the moment you've all been waiting for," he bellowed into the microphone. "The individual overall highest scorer is..."I squeezed my eyes shut, mentally preparing myself for disappointment. After all, there were so many brilliant students competing this year. What were the chances it could be me?"Jane Doe!"Wait, what? I must have misheard. There's no way...But then I saw it with my own eyes - my name proudly displayed at the top of the winners' list. I had placed first overall in the entire academic decathlon! Shock and disbelief quickly gave way to pure, unrestrained joy."Oh my gosh, oh my gosh!" I shrieked, jumping up and down unable to contain my excitement. My friends rushed over to congratulate me with hugs and high-fives. I could barely process what was happening - this was legitimately a dream come true.You see, ever since I was a little kid, academics have always been my biggest passion. I was that annoying kid who actuallyenjoyed homework and would beg my parents for extra workbooks and practice tests for fun. My friends would make fun of me for being such a nerd, but I took pride in it. Getting good grades and acing exams wasn't just about achieving success for me - it was about pushing myself and discovering how far my abilities could take me.So when I learned about the academic decathlon in middle school, I knew it was made for someone like me. Ten different events testing every subject from mathematics to literature to economics? Sign me up! I started training immediately, devouring thick tomes of information and drilling practice questions for hours on end. Some people made fun of my intense dedication, saying I needed a life outside of academics. But they didn't understand - this WAS my life, and I loved every second of it.Over the years, I became known among my peers as "the smart kid" who was gunning for decathlon glory. With each passing year, I became more driven, more focused, and frankly more obsessed with finally taking home that top prize. Third place last year just wasn't good enough for my lofty ambitions.Which is why actually accomplishing that lifelong dream of being named the overall highest scorer felt so indescribablyamazing. All those late nights of studying, all those sacrificed weekends, all those moments of self-doubt where I questioned if I was really good enough...they had all led up to this sublime moment of triumph where I had cemented myself as the best of the best. Nothing could steal my joy.As I clutched that hard-earned first place trophy, I knew that the happiness and sense of achievement I felt went beyond just winning a competition. This represented the culmination of years of effort and the ultimate validation of the importance I placed on academics. It was proof that with enough passion and perseverance, even your loftiest goals are achievable.That day, I learned that the true prize wasn't just the trophy itself, but the incredible journey of self-discovery andself-actualization that led me to that stage. The skills I honed, the knowledge I gained, the resilience I built - those were gifts that would stick with me for life no matter what future challenges awaited. And knowing that I had the strength and determination to tackle something as monumental as the academic decathlon meant that I was capable of conquering anything I set my mind to.So yeah, I'd say this has to be one of the most euphoric, gratifying, happiest moments of my life so far. Did I work myselfto the bone to get here? Absolutely. Was it worth every second of blood, sweat, and tears? You'd better believe it. I have never felt so proud, so accomplished, or so genuinely elated. And you can bet I'll be savoring this hard-earned victory for a long, long time!篇2The Ecstatic Euphoria of Academic ExcellenceOh my days, you guys! I can scarcely believe the words that are about to leave my lips – no, I can't even call them mere words. These are the sweetest syllables, the most mellifluous melodies, the undisputed anthems of my academic triumph! I, your friendly neighborhood bookworm, your perpetually pencil-gnawing pal, have managed to secure the coveted first rank in our batch!Wow, just letting those words roll off my tongue gives me a high that no substance could ever match. It's like my brain is frolicking through fields of unrestrained jubilation, doing cartwheels amid the daffodils of delight. Forgive me if I come across a tad overzealous, but you must permit me to revel in this moment. After all, how often does one get to experience the stratospheric elation of outshining every other student in their academic cohort?The journey, as you can imagine, was arduous – an unrelenting gauntlet beset with obstacles that would make even the most diligent scholar quail. Endless nights devoured by the lurid glow of the desk lamp, sustaining myself on little more than a noxious slurry of lukewarm coffee and rapidly congealing takeout. Accommodations that essentially amounted to a fortressed study-cave, hermetically sealed off from all potential distractions and sources of frivolous merriment.My exploits became the stuff of legend, inspiring awe and no small amount of concern from my less formidable peers. Subterranean excursions into the labyrinthine stacks of the university library, hunting for those last elusive morsels of knowledge that would propel me to unprecedented scholastic heights. Arguments with tutors that raged long into the witching hour, vociferously contesting even the most minute points of academic doctrine.In truth, there were moments when I sorely questioned the sanity of my pursuits. When the mounds of crumpled drafts threatened to bury me alive, and the pitiless crimson slashes of editing pens disfigured my work into wretched, unrecognizable shades of their former selves. Tears were shed, existential crises weathered – but still, I persevered.For you see, my friends, I had a dream – nay, an unshakable conviction – that one day, my name would be called to receive the greatest academic laurels our institution could bestow. That all the sleepless nights, all the monastic self-denial, all the Faustian pacts with my studies would amount to something transcendent, something... glorious!And now, I have the ultimate validation, the loftiest vindication that my efforts were not in vain. When that envelope bearing my academic destiny slid into my clammy, trembling hands, it was as if the heavens themselves parted to bathe me in hallowed rays of success. The name emblazoned upon that cursive script in a shall henceforth be spoken in reverential tones, for it belongs to none other than your esteemed batch topper!I could scarcely restrain my glee as I hurried home, letter crumpled in my sweat-slick grasp, eyes glistening with crazed exhilaration. Let it be known that upon receiving this news, I embarked upon a jubilant anatticcapade the likes of which my bemused neighbors have scarcely witnessed! I whirled, I pirouetted, I executed a frenetic jig that united the raw energy of a break-dancer with the elegant poise of a prima ballerina.My family watched on with expressions vacillating between profound bewilderment and reluctant amusement as Iproclaimed my triumph to the unamused neighborhood cats. Serenading our battered garden gnome with spirited renditions of my favorite pop-punk ballads, I capped off the night by plunging headfirst into our ornamental koi pond, preserving for posterity the perfect crystalline imprint of my radiant victor's smile!So here I stand, garbed in the ceremonial graduation robes of champions, a laurel wreath haphazardly askew upon my brow. The boundless gratification of academic conquest courses through my veins, threatening to make my heart burst forth from my chest in a prismatic supernova of pride. For on this day, this exalted zenith of illustrious scholastic performance, I have transcended the ranks of ordinary students.Henceforth, I shall be elevated into the immortal pantheon of hallowed educational deities! Statues shall be carved in my likeness, reverentially placed amid the ivied hushes of venerable learning halls. Wide-eyed acolytes will crowd my lectures, feverishly scribbling down every scintilla of erudite wisdom that escapeth these sanctified lips. Centuries from now, mighty rulers shall still bear the whispered counsels of my teachings to their attentive posterity.So drink deep of this triumph with me, my friends! Let the sweet amnion of success wash over you, buoying you aloft unto realms of intellectual paradise. For though the path was treacherous, though the costs immeasurable, I can at last declare, with every fiber of my being, that it was all unutterably, inexorably... worth it.篇3The Euphoric Triumph of Topping the ClassWords can scarcely capture the tidal wave of unbridled euphoria that washed over me when I learned that I had secured the highest marks in the entire grade. The moment Mrs. Roberts announced my name, my heart leapt into my throat, and a kaleidoscope of emotion detonated within me. Disbelief intermingled with sheer ecstasy, setting off a dizzying spiral of elation that left me lightheaded and weak in the knees.In that transient yet eternal instant, a myriad of memories came flooding back to me – the grueling all-nighters spent poring over textbooks, the innumerable sacrifices of leisure and social engagements, the relentless pursuit of academic excellence that had consumed my every waking moment. Each recollection served as a poignant reminder of the blood, sweat,and tears I had invested in this quest, rendering the present triumph all the more sweet and hard-earned.As I tentatively made my way to the front of the auditorium, a deafening roar of applause and cheers erupted from my peers, their joyous acclamations a resounding affirmation of my accomplishment. With each step, the gravity of the situation intensified, and an overwhelming sense of pride and gratitude threatened to bring me to my knees. I had not only proven my academic mettle but had also earned the respect and admiration of my classmates – a feat that filled me with an indescribable sense of fulfillment.Upon receiving the gleaming trophy that symbolized my hard-won victory, I found myself momentarily rendered speechless, my emotions too raw and visceral to articulate. As I gazed upon the engraved emblem, a physical embodiment of my dedication and perseverance, tears of joy welled up in my eyes, a release valve for the torrent of feelings that threatened to overwhelm me.In that moment, I was acutely aware of the sacrifices my parents had made to ensure my success, the unwavering support they had provided, and the faith they had placed in me. Their beaming smiles, radiating with pride and love, served as apoignant reminder of the profound impact this achievement would have on their lives, a tangible manifestation of their unwavering belief in my abilities.As I clutched the trophy to my chest, a profound sense of gratitude washed over me, directed not only towards my parents but also towards my teachers, whose tireless efforts and unwavering guidance had illuminated my path to success. Their dedication, patience, and belief in my potential had been the bedrock upon which this triumph was built, and I vowed to honor their invaluable contributions by continuing to strive for excellence in all my future endeavors.In the days and weeks that followed, the euphoria of my achievement remained a constant companion, a warm glow that suffused my every waking moment. Each time I gazed upon the trophy, I was transported back to that magical instant, reliving the exhilaration and pride that had coursed through my veins. It served as a potent reminder of the heights to which hard work, dedication, and an unwavering belief in oneself can propel an individual.Yet, amidst the jubilation, I remained grounded, keenly aware that this triumph was but a stepping stone on a journey that stretched out before me, replete with challenges andopportunities alike. I knew that the true test lay not in basking in the glory of this singular achievement but in maintaining the discipline, focus, and hunger that had propelled me to this pinnacle.As I embarked upon the next phase of my academic journey, I carried with me the lessons learned from this experience – the importance of perseverance, the value of hard work, and the unshakable belief that no dream is too ambitious, no goal too lofty, for those willing to pay the price in sweat and determination.This triumph, I realized, was not merely a personal victory but a testament to the transformative power of education, a living embodiment of the adage that knowledge is the greatest equalizer. It was a resounding affirmation that, in the realm of academia, the playing field is level, and those who are willing to invest the effort and make the sacrifices can scale the loftiest of heights, regardless of their circumstances or background.As I look back upon that unforgettable day, the euphoria remains undiminished, a cherished memory etched indelibly into the fabric of my being. It was a moment that redefined my perception of my own capabilities, shattering self-imposedlimitations and igniting within me a burning desire to continue pushing boundaries and defying expectations.In the years to come, I know that I will face numerous challenges and obstacles, moments of doubt and adversity that will test the very limits of my resolve. Yet, whenever those moments arise, I need only conjure the memory of that euphoric triumph, that all-consuming sense of joy and accomplishment, to find the strength and determination to forge ahead, undaunted and unyielding.For in that moment, I learned a lesson more profound than any textbook could impart – that the greatest victories in life are not measured by the spoils of triumph but by the journey undertaken, the obstacles overcome, and the indomitable spirit forged in the crucible of perseverance. And it is this spirit, this unwavering resolve, that will propel me forward, ever onward, towards new heights and horizons yet unexplored.。

Guided practice (exercises, oral practice and group work)ⅥT eaching Process1. Pre-reading activities1) W arm-up questionsWhere did we come from?How did the universe come into being?Are we alone in the universe? Is there any other life out there?What is the future of the human race?2) Introduce Stephen Hawking’s family, education, marriage, disease, contribution3) Let students discuss what contributes to Stephen Hawking’s success2. Text organizationThe text can be divided into 4 parts:Part I (para1-2)Stephen Hawking is known to millions, far and wide, for one of his science book and two questions about his achievements and his disabilitity.Part II (para3-5) Hawking was born to intellectual, eccentric parents, and he was also greatly influenced by famous scientist Galileo.Part III (para6-10) Hawking showed his intelligence and gift at school.Part IV (para11-14) Hawking gained success in science in spite of his disability.3. Background informationGuinness Book of W orld Records.In 1955, Norris and his twin brother Ross edited the first Guinness Book of World Records. The book was first designed to record the then extremes in, on and beyond the Earth —notably in human performance and of the natural world. The name “Guinness” derives fromthe Guinness Brewery in Dublin, which was Ireland’s largest company. It is in London now. The book is now published worldwide in 23 different languages.The Sunday TimesThe Sunday Times is an influential Sunday newspaper published in London, England. It is known around the world for the quality of its reporting and editing and for its coverage of British politics and the arts. Founded in 1822 as a nationally circulated paper with an independent editorial policy, The Sunday Times reflects the dignified, carefully written, and well-edited character of its daily counterpart The Times.4. Skill learning in writing and readingA) Writing Skill: Coming up with examples to support the general statement.When writing, we usually put forward some general statements, then we list several examples to illustrate the general statementsNow, analyze the following sample paragraph:No one is smart at everything or smart all the time. Einstein, for instance, failed many classes in grammar school because of his terrible spelling. And he was well known among his colleagues for being forgetful. He was always losing his keys, and one famous day he came to work with a clothes hanger still inside his jacket.General statement: No one is smart at everything or smart all the time.Example1:Einstein, for instance, failed many classes in grammar school because of his terrible spelling.Example2: And he was well-known among his colleagues for being forgetful. He was always losing his keys, and one famous day he came to work with a clothes hanger still insid e his jacket.B) Reading Skill: Understanding the figurative languageAuthors often use figures of speech, or figurative language, to make their writing lively and memorable. Like idiomatic expressions, figures of speech can be confusing if you try to understand them literally—but for effective readers, who know how to recognize and interpret them, figures of speech can help you understand the author’s meaning more deeply and think about ideas in new ways.Comparisons, personification and symbolism etc. are all figurative languages.5.

The family car was a second-hand car bought for ￡50 from a London taxi company.The description of Hawking's parents' house suggests their "eccentric “behaviors in other people's eyes and, on the other hand, their thrift in life: they would rather buy themselves in a roomful of books than have any comforts in their house.peel:vi.

Among the courses listed bellow, I have a preference for sports, literature and cooking. As is known to all, it’s more important to have good health than wealth. Nothing can we do if we only do little exercise and become unhealthy. Our mind should also be trained. It’s high time that we should get close to literature so as to enrich our knowledge.
What’s more, as we will get into society and should depend on ourselves some day, cooking won’t be a useless skill for us to learn. There is no doubt that it will cost a great deal of money if we go to restaurant for meals every day.
Great as optional courses are, we can choose the ones we really like, which will surely develop our passion to learn and
increase our studies. Besides, it can also decorate our rough life so that it will become a more colourful one.
One possible version:
It is really exciting that our school will offer many optional courses, from which we can choose four. The courses can be listed as follows: sports, music, science, business, literature,
drawing, cooking, clothing design, architecture, and film directing.
To my excitement, the courses include my favorites. I’m eager to learn clothing design, film directing, business, and music. As a girl, I have great passion for beautiful clothes, hoping to be a clothing designer. And the reason why I would like to choose film directing is that I think
making a film is amazing . When it comes to business, I believe knowing something about business is a must for our future life . Above all, music is my best love. Music can bring me calmness and relaxation.
From my perspective, optional courses can build a bridge , leading us to touch the real world. Not only can we develop our interests, but also put the knowledge
into practice. Only in this way can we gain wholesome development.。
