一起来看看科学家的演讲稿不少于600字五篇,欢迎查阅!科学家的演讲稿不少于600字1谈到最尊敬的科学家,肯定每人都有不同的看法,而我最尊敬的科学家是斯蒂芬.威廉.霍金,他是一个让我深深震撼的人!他在1942年生于牛津,在他21岁时被确诊患有肌萎缩性侧索硬化症,之后被禁锢在轮椅上长达40年之久,只剩下右手一个大拇指会操纵,全身仅三个手指能动!几年下来他克服了种.种困难!不顾艰辛的编写伦理宇宙,伦理黑洞,伦理大爆炸!的书籍,但是我们值得一注意的是,他全身只有一根手指可以来动,他的秘书曾私下对别人讲,他写一篇1小时的演讲稿需要3天的时间,打一段话需要近乎一个小时!但是令人惊讶的霍金坚持下来了!在他不懈的努力下一册册的书籍出现在我们世人的眼前。
要知道这是他一个人,坐在一个40年都没有离开的轮椅上,用仅可以动的一只手指在一个小小的鼠标上来编写出来的!霍金一生贡献於理论物理学的研究,被誉为当今最杰出的科学家之一。
他的著作包括《时间简史》及《黑洞与婴儿宇宙以及相关文章》。
虽然大家都觉得他非常不幸,但他在科学上的成就却是在他在病发后获得的。
他凭著坚毅不屈的意志,战胜了疾病,创造了一个奇迹,也证明了残疾并非成功的障碍。
他对生命的热爱和对科学研究的热诚,是值得年轻一代学习的。
霍金的魅力不仅在于他是一个充满传奇色彩的物理天才,也因为他是一个令人折服的生活强者。
他不断求索的科学精神和勇敢顽强的人格力量深深地吸引了每一个知道他的人。
我尊敬他!我崇拜他!但是尊敬崇拜之后,我们是否也应该静下来想一想,如果连一个全身瘫痪,只有一根手指可以动的残疾人都可以成为世界著名的物理学家,那我们这些正常人是否可以做的更出色?我们有健壮的双腿、这可以为我们节约许多生活上自理因自理而浪费的时间,我们有灵活的双手、可以为我们节约许多因为打字所浪费的时间,我们还有许许多多的东西比霍金在身体方面上强。
中小学生关于我敬佩的科学家演讲稿

中小学生关于我敬佩的科学家演讲稿中小学生关于我敬佩的科学家演讲稿篇1 大家好:老师、同学们,大家知道伽利略是谁吗?他是一位着名的科学家,他提出了两个铁球同时着地的新定论,从而改变了人们陈旧的思想。
所以,他是我最敬佩的科学家。
下面,我们来听一个他的故事吧。
在以前,人们都听从古希腊科学家亚里士多德的定论。
但伽利略并不认为两个不一样重的铁球,重的先落地。
这条定论是对的。
于是,他反复试验证明了他是正确的。
之后,又到埃菲尔铁塔上做公开实验,证明了两个铁球同时着地。
他让我敬佩的原因有三点:第一是因为他对科学、对工作都十分严谨认真。
因为他在想到这个定论有可能不正确时,并没有盲目下结论,而是反复进行试验,才下了结论。
而我们时常都不这样认真,只是匆忙下结论,从而造成了很大的失误。
第二是因为他有坚持真理的精神。
因为他在进行公开实验前,遭到他人唾弃,但他始终坚信真理,而使他成功。
但在我们之中,有人经常做墙头草,始终依靠强势力,从而让真理渐渐消失。
第三是因为他有创新精神。
因为他在亚里士多德的定论下,有自己的思想从而改变了世人的观点。
创新这种精神,往往很重要。
因为如果人们总沉浸在陈旧的思想中,就会形成错误的观念。
而往往有一些人,提出新的观点,改变了人们的错误,使人们慢慢地进步。
我认为,我们要学习伽利略的认真、坚持真理和创新精神!谢谢大家!我的演讲完毕!中小学生关于我敬佩的科学家演讲稿篇 2 我们现在便利的生活,丰富的知识,都是从古至今许许多多的科学家和发明家总结和制造出来的,而在这许许多多的科学家中,我最敬佩的是著名的物理学家牛顿。
一六四二年,牛顿出生在英国东南部伍尔斯沙浦村的一个农民家庭。
在他还很小的时候,父亲就因病去世了。
又因生活所迫,母亲改嫁。
年幼的小牛顿只好和外祖母一起生活,尽管家境贫寒,但外祖母还是想法设法让牛顿上学,牛顿他非常喜欢数学,对劳技课也非常感兴趣,牛顿的第一件手工作品是水钟,是计算时间用的,这件作品受到了老师的表扬,从此,牛顿对手工更有兴趣了。
关于科学家的英语作文金句

关于科学家的英语作文金句In a world where labels and definitions often dictate our paths, it is refreshing to consider the concept of None. This intriguing idea invites us to explore the vast expanse of possibility that exists beyond the confines of predetermined categories and societal expectations. By embracing the notion of None, we open ourselves to a realm of limitless potential where the boundaries of our identity and purpose are not predetermined but rather shaped by our own unique journeys.At the heart of None lies the notion of freedom – freedom from the constraints of societal norms, from the expectations of others, and from the limitations we often impose upon ourselves. It is a state of being that transcends the traditional constructs of identity, allowing us to shed the layers of preconceived notions and truly discover who we are, unencumbered by the weight of external influences. In a society that thrives on categorization, the concept of None challenges us to redefine our understanding of self. It invites us to explore the vast expanse of our inner landscapes, to delve into the depths of our passions, aspirations, and values, and to carve out a path that is uniquely our own. By embracing None, we embark on a journey of self-discovery where the answers we seek are not found inthe labels and definitions imposed upon us, but rather in the uncharted territories of our own being.One of the most profound aspects of None is its ability to liberate us from the fear of the unknown. In a world that often prizes certainty and predictability, the concept of None challenges us to embrace the uncertainty of the future, to let go of the need for control, and to surrender to the infinite possibilities that lie before us. This shift in perspective can be profoundly empowering as it allows us to approach life with a sense of curiosity, wonder, and openness to the unexpected. As we navigate the complexities of our lives, the concept of None can serve as a guiding light, reminding us to trust in the unfolding of our own stories. It encourages us to let go of the need to conform to societal expectations and to instead focus on cultivating a deep understanding of our authentic selves. By embracing None, we can tap into our innate creativity, our resilience, and our ability to adapt and grow in the face of life's challenges.Moreover, the concept of None holds the potential to foster a more inclusive and compassionate society. By recognizing that we are not defined by the labels and categories that often divide us, we can cultivate a deeper sense of empathy and understanding for those who may not fit neatly into societal norms. This shift in perspective can lead to the dismantling of prejudices, the breaking down of barriers, and the creation of a world where diversity is celebrated andeveryone is afforded the freedom to be their authentic selves.In a world where we are constantly bombarded with messages about who we should be and how we should live, the concept of None offers a refreshing alternative. It invites us to step back from the noise of societal expectations and to reconnect with the essence of our being. By embracing None, we can reclaim our power to define our own paths, to explore the depths of our passions and aspirations, and to cultivate a profound sense of purpose and fulfillment.One of the key benefits of embracing the concept of None is the opportunity it presents for personal growth and transformation. When we let go of the constraints of predetermined identities, we open ourselves up to a world of possibilities. We can experiment with new ways of being, try on different roles and perspectives, and ultimately uncover the unique tapestry of our authentic selves. This process of self-discovery can be both exhilarating and challenging, as we confront the fears and doubts that may have held us back in the past. However, by embracing the uncertainty and vulnerability inherent in the concept of None, we can emerge with a deeper understanding of who we are and a renewed sense of purpose.Moreover, the concept of None can also have profound implications for our relationships and social interactions. When we let go of the need to fit into predetermined categories, we can approach otherswith a greater sense of openness and curiosity. We can move beyond the superficial labels and assumptions that often divide us, and instead, seek to understand the unique stories and experiences that shape each individual. This shift in perspective can foster more meaningful connections, deeper empathy, and a greater appreciation for the diversity of the human experience.In a world that often prioritizes conformity and homogeneity, the concept of None offers a powerful counterpoint. It reminds us that our true worth and value lie not in the labels and definitions imposed upon us, but in the rich tapestry of our own unique experiences, passions, and aspirations. By embracing None, we can cultivate a sense of self-acceptance and self-love that transcends the limitations of societal expectations, and instead, focus on the boundless potential that exists within each of us.Ultimately, the concept of None is not about the absence of identity or purpose, but rather, the freedom to define those things for ourselves. It is a radical invitation to step outside the confines of the familiar and to explore the vast expanse of our own being. By embracing None, we can discover the true essence of who we are, unencumbered by the weight of external influences and the constraints of societal norms. In doing so, we can not only transform our own lives but also contribute to the creation of a more inclusive, compassionate, and vibrant world.。
科学家的故事演讲稿300字

科学家的故事演讲稿300字篇一尊敬的老师、亲爱的同学们:大家好!我演讲的题目是:我最敬佩的一位科学家。
我最敬佩的一位科学家是牛顿。
我之所以敬佩他,是因为他有着做事专心、勤学勤思、坚持不懈执着追求、刻苦钻研的精神。
牛顿做事很专心。
有一次,牛顿在实验室里做实验,忘记了吃饭时间。
助手拿了几个鸡蛋让牛顿自己煮。
牛顿随手拿了小锅,把鸡蛋放在锅里,开好炉子又开始做实验。
做完了实验,他才想起锅里的鸡蛋。
打开锅盖一看,里有没有蛋,只有一个怀表。
原来牛顿过于专心做实验,把怀表当成鸡蛋煮了。
牛顿很善于思考。
有一次,牛顿坐在乡间的一棵苹果树下沉思。
忽然一个苹果掉在地上。
于是,他开始了研究。
他发现所有东西一旦失去支撑必然会坠下,继而他发现任何两物体之间都存在着吸引力,而这引力更与距离的平方成反比,从而总结出万有引力定律。
牛顿也非常执着追求。
在他小时候,当时封建社会的"英国等级制度很严重,中小学里学习好的学生还经常歧视学习差的同学。
有一次课间游戏,大家玩得兴高采烈的时候,一个学习好的同学借故踢了牛顿一脚,并骂他笨蛋。
牛顿的心灵受到刺激,愤怒极了。
他想,我俩都是学生,我为什么受他的欺侮?我一定要超过他!从此牛顿下定决心,发奋读书,他早起晚睡,争分夺秒,刻苦学习。
经过努力,牛顿的学习成绩不断提高,不久就超过那个曾欺侮过他的同学,名列班级前茅,为自己挽回了荣誉。
正是牛顿拥有了这些良好的品质,最终成就了一位伟大的科学家。
我们要学习牛顿这些刻苦钻研坚持不懈,一丝不苟的精神,做一个品学兼优的好学生。

著名的英文励志演讲稿

Ladies and Gentlemen,Good morning/afternoon/evening. It is my great honor to stand before you today and share my thoughts on a subject that has shaped my life and has the potential to change yours: the power of determination. As we navigate through the complexities of life, it is often determinationthat separates the ordinary from the extraordinary, the successful from the unsuccessful.Let us begin with a story. There once was a young man named Thomas Edison who, at the age of 10, set a goal to become an inventor. His journey was fraught with challenges, and he often faced criticism and setbacks. But Thomas never gave up. He believed in the power of determination, and he knew that success was within his grasp. Years later, he achieved his goal and became one of the most influential inventors in history, with over 1,000 patents to his name. ThomasEdison's story teaches us that determination is the key to overcoming adversity and achieving greatness.Now, let us delve deeper into the essence of determination. Determination is not just about having a goal; it is about the unwavering commitment to achieving that goal, despite the obstacles that stand in our way. It is the inner strength that propels us forward, even when the path ahead seems uncertain and daunting.The first step in harnessing the power of determination is to set clear, achievable goals. Goals give us direction and purpose, and they provide us with a roadmap for success. However, it is important to set realistic goals that we can work towards, rather than aiming for the stars and becoming discouraged when we fall short. Remember, even the smallest steps forward are progress.Once we have set our goals, we must develop a plan to achieve them. This plan should outline the specific actions we need to take, the resources we require, and the timeline for completion. A well-thought-out planwill not only keep us focused but also help us to stay on track, even when faced with unexpected challenges.The next crucial element in harnessing the power of determination is resilience. Resilience is the ability to bounce back from failure and setbacks. It is the mental toughness that allows us to rise above adversity and continue moving forward. Resilience is not something we are born with; it is a skill that can be developed through practice and experience.One of the most significant lessons I have learned in life is that failure is not the opposite of success, but rather a stepping stone to it. Every failure teaches us something valuable, and every setback is an opportunity to grow stronger. When we face failure, we must embrace it as a learning experience, analyze what went wrong, and use that knowledge to improve our approach.Another vital aspect of determination is persistence. Persistence is the relentless pursuit of our goals, even when we feel like giving up. It is the refusal to accept defeat, the willingness to keep pushing forward, and the unwavering belief in our own abilities. Persistence is what separates the successful from the unsuccessful, the dreamers from the doers.To illustrate the power of persistence, let me share another story. There was once a woman named Helen Keller who, at the age of 19 months, became deaf and blind due to an illness. Despite her disabilities, Helen never gave up on her dreams of education and communication. With the help of her teacher, Anne Sullivan, Helen learned to read, write, and speak. She went on to become one of the most influential deaf and blind individuals in history, an author, a lecturer, and a peace activist. Helen Keller's story demonstrates that with determination and persistence, anything is possible.As we strive to harness the power of determination, we must also remember the importance of self-belief. Self-belief is the foundation upon which determination is built. It is the inner voice that tells us we can do it, that we are capable of achieving greatness. When we believe in ourselves, we are more likely to overcome obstacles and persist in the face of adversity.In conclusion, determination is the key to overcoming adversity and achieving greatness. It is the unwavering commitment to our goals, the resilience to bounce back from failure, and the persistence to keep pushing forward. By setting clear goals, developing a plan, embracing failure as a learning experience, and believing in ourselves, we can tap into the power of determination and achieve our dreams.Ladies and gentlemen, let us not underestimate the power of determination. Let us be inspired by the stories of individuals who have overcome insurmountable odds to achieve greatness. Let us remember that determination is within us all, waiting to be unleashed. With determination, we can conquer the world and achieve the greatness that lies within us.Thank you.。
星球介绍英文演讲稿三分钟(3篇)
第1篇Good day! Today, I stand before you to introduce you to a remarkable world that lies beyond our solar system—a world that has piqued the curiosity of scientists and dreamers alike. Welcome to the planet of Zephyria.Zephyria is a gas giant, similar in size to Jupiter, but with a unique set of characteristics that make it an extraordinary place. It islocated in the constellation of Andromeda, approximately 12 light-years away from Earth. Our journey to Zephyria has been a collaborative effort between human astronauts and advanced artificial intelligence, and I am honored to share with you the wonders of this distant world.Firstly, let's talk about the atmosphere. Zephyria is shrouded in athick layer of ammonia hydrosulfide clouds, which give it a distinctblue-green hue. These clouds are so dense that they form a complex weather system, complete with swirling vortexes and towering storms that can last for days. Unlike Earth, the winds on Zephyria are not driven by heat from the sun but by the planet's internal heat, creating a dynamic and ever-changing landscape.Moving on to the planet's interior, Zephyria has a solid core made of rock and ice, surrounded by several layers of metallic hydrogen. This unique composition allows Zephyria to generate a powerful magnetic field, which protects the planet from harmful solar radiation and helpsmaintain its stable atmosphere. The magnetic field also plays a crucial role in creating the stunning auroras that can be seen from space, asight that has left our astronauts in awe.Now, let's delve into the life forms that call Zephyria home. Despite being a gas giant, Zephyria harbors a diverse ecosystem that thrives in the extreme conditions. Microscopic organisms have been discoveredliving in the ammonia clouds, feeding on the chemicals released by the planet's storms. These tiny creatures have adapted to the frigid temperatures and high pressure, and they play a vital role inmaintaining the planet's atmospheric balance.One of the most fascinating aspects of Zephyria's ecosystem is the presence of floating islands. These islands are composed of a spongy material called zephyrite, which is found in abundance beneath the clouds. The islands are home to a variety of plant and animal species, some of which have evolved to use the planet's powerful magnetic field for navigation and communication. This unique adaptation has led to the development of an intricate web of social structures and complex mating rituals, which our scientists have been studying closely.The surface of Zephyria is, however, not visible to us. Our robotic probes have captured images of vast oceans of liquid methane and ethane, which cover the planet's surface. These oceans are home to colossal creatures, such as the zephyriaphage, a colossal predator that has a symbiotic relationship with the floating islands. The zephyriaphage feeds on the organisms that inhabit the islands, while providing protection from other predators.In addition to its biological wonders, Zephyria has geological features that are unparalleled in our solar system. The planet is dotted with volcanic islands, which erupt with a variety of gases and minerals. These eruptions are not only fascinating to observe but also have the potential to impact the planet's atmosphere and climate. Our scientists are particularly interested in studying these volcanic activities, as they could provide insights into the early formation of gas giants and the potential for life in other solar systems.As we continue to explore Zephyria, we have also discovered that the planet has a moon, Zephyria Luna, which is of significant scientific interest. The moon is a small rocky body that orbits Zephyria at a distance of about 50,000 kilometers. It is believed to have been formed from the debris left over from the planet's formation. Zephyria Luna has a thin atmosphere and a surface that is home to a variety of extremophile organisms, which have adapted to the harsh conditions of space.In conclusion, Zephyria is a world of endless fascination and discovery. Its unique atmosphere, powerful magnetic field, diverse ecosystem, and geological wonders make it a paradise for scientists and dreamers alike.As we continue to explore this distant world, we are not only expanding our knowledge of the universe but also gaining a deeper understanding of life's potential to thrive in extreme environments.Thank you for joining me on this journey to Zephyria. May our exploration inspire future generations to continue the quest for knowledge and understanding of the cosmos.第2篇Good morning/afternoon/evening. Today, I am honored to stand before you to introduce a fascinating planet that has intrigued scientists and dreamers alike for centuries.

It is the third-largest planet in its solar system, trailing only the sun and the gas giant, Zephyria. Xylaria's diameter is roughly 1.2 times that of Jupiter, making it a colossal presence in the cosmos.The planet's atmosphere is a mesmerizing blend of nitrogen, oxygen, and methane, with traces of other gases. The dominant color of the sky is a deep azure blue, reminiscent of Earth's own atmosphere. However, the most captivating feature of Xylaria's atmosphere is the presence of bioluminescent clouds. These clouds emit a soft, ethereal glow that dances across the sky, creating a mesmerizing spectacle for any observer.Xylaria's surface is a vast ocean, covering approximately 85% of the planet's total area. The ocean is characterized by its vibrant blue and green hues, with periodic bursts of bioluminescent waves. The ocean's depths are home to a plethora of life forms, many of which have never been seen on Earth. These organisms have adapted to the extreme conditions of Xylaria's ocean, displaying a remarkable diversity of forms and behaviors.One of the most intriguing features of Xylaria's surface is the presence of floating islands. These islands are made of a gelatinous substance that allows them to float on the ocean's surface. The islands vary insize and shape, some resembling intricate patterns, while others are more abstract. The floating islands are home to various species of plants and animals, each uniquely adapted to their floating environment.Xylaria's climate is both extreme and diverse. The planet experiences intense storms, with lightning strikes and tornadoes that dwarf anything we have ever witnessed on Earth. However, the planet also boasts some of the most serene weather patterns, with gentle breezes and soft rain. The temperature on Xylaria varies greatly, with some regions experiencing frigid temperatures and others enjoying a tropical climate.The planet's moons are also of great interest. Xylaria has four moons, each with its unique characteristics. The largest moon, Helia, is a rocky body that orbits Xylaria closely. Helia's surface is marked by craters and mountains, creating a rugged and picturesque landscape. The other three moons are smaller and composed of ice, making them ideal candidates for future exploration.The inhabitants of Xylaria are a curious and intelligent species known as the Xylarians.

Today, I stand before you to introduce a world that is shrouded in mystery and wonder—a world that lies beyond the stars we see in the night sky. Welcome to the planet Xylara, a celestial gem that promises to unveil secrets of the universe like no other.Xylara is located in the Andromeda Galaxy, a mere 2.5 million light-years away from our solar system. It orbits a G-type star, much like our Sun, but with a few key differences that make it a unique habitat for life as we know it.The diameter of Xylara is approximately 1.2 times that of Earth, which means it has a larger gravitational pull but still maintains a stable atmosphere. The planet's rotation period is about 24.6 Earth days, resulting in a day that is almost identical to ours. This synchronization allows for the presence of a single moon, Xylarion, which orbits the planet every 27.3 Earth days, creating a beautifultidal locking effect that ensures a consistent day and night cycle on Xylara.The atmosphere of Xylara is a blend of nitrogen, oxygen, and carbon dioxide, with trace amounts of other gases such as methane and ammonia. This composition is similar to Earth's, which suggests that the planet could have supported life at some point in its history. The presence of liquid water is a testament to the planet's favorable conditions. Xylara has two oceans, the Pacifica and the Atlanticus, which cover about 75% of the planet's surface, providing ample resources for any potential inhabitants.The surface of Xylara is characterized by diverse landscapes. The continents are marked by lush green forests, vast savannas, and towering mountains. The planet's poles are capped with ice caps, which have been stable for millions of years. The temperature is regulated by acombination of factors, including the tilt of the planet's axis, which allows for a mild climate year-round.The most fascinating feature of Xylara is its geothermal activity. The planet has a network of geysers and volcanoes that emit steam, hot springs, and mineral-rich water. These geysers are not only a source of energy but also provide a unique ecosystem where extremophiles thrive. These organisms have adapted to survive in high temperatures and pressure, suggesting that life on Xylara could be more resilient than on Earth.In the skies above Xylara, the celestial phenomena are breathtaking. The planet orbits its star at a distance that allows for four seasons, each with its own unique characteristics. The colors of the sky change with the seasons, ranging from a deep blue during the summer to a vibrant green during the winter. The moon, Xylarion, is visible in the sky, often casting a soft glow over the planet's surface.In terms of flora and fauna, Xylara is a paradise. The planet is home to a variety of species, including intelligent life forms that have evolved to utilize the geothermal energy and abundant water resources. These beings have developed a sophisticated society, with cities and civilizations that reflect their harmonious relationship with nature.The language spoken on Xylara is a melodic dialect that echoes the planet's beauty. The music and art forms are inspired by the natural wonders of the world, and the people are known for their creativity and compassion.In conclusion, Xylara is a planet that captivates the imagination and challenges our understanding of life in the universe. Its unique combination of geothermal activity, stable climate, and richbiodiversity make it a prime candidate for exploration and potential colonization. As we continue to explore the cosmos, we must rememberthat each planet we discover is a piece of a vast puzzle that tells the story of life's possibilities.Thank you for joining me on this journey to Xylara.

在我们平凡的日常里,演讲稿与我们的生活息息相关,相信很多朋友都对写演讲稿感到非常苦恼吧,以下是小编为大家收集的科学家的演讲稿,欢迎大家分享。
科学家的演讲稿1李四光,我国著名地质学家,地质力学的创始人。
在上世纪20年代,他首先发现了我国存在的第四纪冰川遗迹,提出了地质力学的构造理论。
曾任中华人民共和国地质部部长,中国科学技术协会主席。
李四光出生在一个贫困的家庭里,全家人只靠父亲做私塾老师的一点点收人生活,有时候父亲收的学生不多,家里就可能断炊,生活非常困苦,俗话说:“穷人家的孩子早当家.”在这样的环境下,李四光从小就非常懂事,总是抢着做一些力所能及的家务,如放羊、砍柴、挑水、打扫房子等力所能及的家务。
6岁的时候,李四光开始到父亲的私塾念书。
他非常喜爱学习,每天除了上课,做家务,一有闲暇,就忙着背课文,练书法,写作文,忙个不停。
李四光十分富有同情心,因为自己家里贫困,特别能理解其他穷人。
一次,一个小偷悄悄钻进私塾,想趁大家不注意的时候,偷走住宿同学盖在被子上的棉衣。
不料却被同学发现,马上大喊:“小偷,抓小偷啊!”大家一拥而上把小偷打倒在地,然后用绳子吊在院里的树上。
同学里只有李四光没有动手。
看着面黄肌瘦的小偷,李四光知道小偷也是穷人家的孩子,逼急了才偷东西。
等大伙散去后,李四光拿来一条凳子放在小偷脚下,免得他被吊得难受;一面劝他不要再偷东西,人穷,要穷得有志气。
李四光在艰苦的环境里任然刻苦的学习,后来成了我国著名的地质学家了。
科学家的演讲稿2今天我想跟大家谈一谈科学,我觉得大家应该很喜欢科学吧,那么也就一定有一个自己最喜欢而且很崇拜的科学家,他是谁呢?我想来跟大家谈谈我最喜欢也很崇拜的科学家——伽利略。

关于伽利略的英文演讲稿 篇一:贝佐斯XX年在普林斯顿的演讲稿中英文 贝佐斯XX年在普林斯顿的演讲稿中英文,贝佐斯作为亚马逊的创始人,获得的成功令众人羡慕不已,他曾在普林斯顿大学求学,在学士毕业典礼上的演讲中也被称之为人生一定要听的十大演讲,不妨看一看吧,献给毕业季的你·~~本篇文章首先作者讲述自己的孩童经历,来证明自己的观点,选择比天赋更重要,全文都围绕着你对自己的选择,追随自己的内心去抉择。 贝佐斯XX年在普林斯顿的演讲稿中英文 we are what we choose as a kid, i spent my summers with my grandparents on their ranch in texas. i helped fix windmills, vaccinate cattle, and do other chores. we also watched soap operas everyafternoon, especially days of our lives. my grandparents belonged to a caravan club, a group of airstream trailer owners who travel together around the and canada. and every few summers, wed join the caravan. wed hitch up the airstream trailer to mygrandfathers car, and off wed go, in a line with 300 other airstream adventurers. i loved and worshipped my grandparents and i really looked forward to these trips. on one particular trip, i was about 10 years old. i was rolling around in the big bench seat in the back of the car. my grandfather was driving. and my grandmother had the passenger seat. she smoked throughout these trips, and i hated the smell. i have a vivid memory of what happened, and it was not what i expected. i expected to be applauded for my cleverness and arithmetic skills. jeff, youre so smart. you had to have made some tricky estimates, figure out the number of minutes in a year and do some division. thats not what happened. instead, my grandmother burst into tears. i sat in the backseat and did not know what to do. while my grandmother sat crying, my grandfather, who had been driving in silence, pulled over onto the shoulder of the highway. he got out of the car and came around and opened my door and waited for me to follow. was i in trouble my grandfather was a highly intelligent, quiet man. he had never said a harsh word to me, and maybe this was to be the first time or maybe he would ask that i get back in the car and apologize to my grandmother. i had no experience in this realm with my grandparents and no way to gauge what the consequences might be. we stopped beside the trailer. my grandfather looked at me, and after a bit of silence, he gently and calmly said, jeff, one day youll understand that its harder to be kind than clever. 在我还是一个孩子的时候,我的夏天总是在德州祖父母的农场中度过。我帮忙修理风车,为牛接种疫苗,也做其它家务。每天下午,我们都会看肥皂剧,尤其是《我们的岁月》。我的祖父母参加了一个房车俱乐部,那是一群驾驶airstream拖挂型房车的人们,他们结伴遍游美国和加拿大。每隔几个夏天,我也会加入他们。我们把房车挂在祖父的小汽车后面,然后加入300余名airstream探险者们组成的浩荡队伍。 我爱我的祖父母,我崇敬他们,也真心期盼这些旅程。那是一次我大概十岁时的旅行,我照例坐在后座的长椅上,祖父开着车,祖母坐在他旁边,吸着烟。我讨厌烟味。 在那样的年纪,我会找任何借口做些估测或者小算术。我会计算油耗还有杂货花销等鸡毛蒜皮的小事。我听过一个有关吸烟的广告。我记不得细节了,但是广告大意是说,每吸一口香烟会减少几分钟的寿命,大概是两分钟。无论如何,我决定为祖母做个算术。我估测了祖母每天要吸几支香烟,每支香烟要吸几口等等,然后心满意足地得出了一个合理的数字。接着,我捅了捅坐在前面的祖母的头,又拍了拍她的肩膀,然后骄傲地宣称,每天吸两分钟的烟,你就少活九年! 我清晰地记得接下来发生了什么,而那是我意料之外的。我本期待着小聪明和算术技巧能赢得掌声,但那并没有发生。相反,我的祖母哭泣起来。我的祖父之前一直在默默开车,把车停在了路边,走下车来,打开了我的车门,等着我跟他下车。我惹麻烦了吗我的祖父是一个智慧而安静的人。他从来没有对我说过严厉的话,难道这会是第一次还是他会让我回到车上跟祖母道歉我以前从未遇到过这种状况,因而也无从知晓会有什么后果发生。我们在房车旁停下来。祖父注视着我,沉默片刻,然后轻轻地、平静地说:杰夫,有一天你会明白,善良比聪明更难。 what i want to talk to you about today is the difference between gifts and choices. cleverness is a gift, kindness is a choice. gifts are easy -- theyre given after all. choices can be hard. you can seduce yourself with your gifts if youre not careful, and if you do, itll probably be to the detriment of your choices. 今天我想对你们说的是,天赋和选择不同。 聪明是一种天赋,而善良是一种选择。天赋得来很容易毕竟它们与生俱来。而选择则颇为不易。如果一不小心,你可能被天赋所诱惑,这可能会损害到你做出的选择。 在座各位都拥有许多天赋。我确信你们的天赋之一就是拥有精明能干的头脑。之所以如 此确信,是因为入学竞争十分激烈,如果你们不能表现出聪明智慧,便没有资格进入这所学校。 你们的聪明才智必定会派上用场,因为你们将在一片充满奇迹的土地上行进。我们人类,尽管跬步前行,却终将令自己大吃一惊。我们能够想方设法制造清洁能源,也能够一个原子一个原子地组装微型机械,使之穿过细胞壁,然后修复细胞。这个月,有一个异常而不可避免的事情发生了人类终于合成了生命。在未来几年,我们不仅会合成生命,还会按说明书驱动它们。我相信你们甚至会看到我们理解人类的大脑,儒勒·凡尔纳,马克·吐温,伽利略,牛顿所有那些充满好奇之心的人都希望能够活到现在。作为文明人,我们会拥有如此之多的天赋,就像是坐在我面前的你们,每一个生命个体都拥有许多独特的天赋。 how will you use these gifts 追随自己内心的热情 listened carefully to me, and finally said, that sounds like a really good idea, but it would be an even better idea for someone who didnt already have a good job. that logic made some sense to me, and he convinced me to think about it for 48 hours before making a final
