In that part of test, we are asked to write a short essay according to a given picture. In the picture, a pair of parents are facing with a computer on the first floor in an apartment. On the screen is a sentence of irony, ‘Dear son, How is your life going on the second floor? We miss you so much. ’Obviously, the picture reflects the common problem in our daily life. Technology has made us and close relatives and friends more distant.We can’t deny that the great benefits brought about by the progress on science and technology is hided in every corner of the world. Modern communication tools such asmobiles and QQ make it possible to send message in a handy way. The Internet enables a pupil to accomplish a university graduation thesis. Powerful networking information storage makes incalculable social activity in an orderly way. Sophisticated scientific techniques even help human to explore other planets. Anyway,the finding of the second earth may give human a newaccomadation after the earth is destroyed. That sounds not bad. As we can see, the rapid development of science and technology has brought great changes to our life. However, some of the influence it takes is not so optimistic. Just like the example I reffered at the beginning. Communicating through social networking web site is becoming a threaten to people’s real life. Against to it’s original willing, we gradually fade out in the crowd. Despite this, children lack essentialinterpersonal skills. Those who indulge in I pad or I phone often isolated and being cut off from the outside world. They tend to be more introverted, self-centered and withdrawn. From another point of view, the technique makes using tools on a large scale become a consequent tendency. You must hear of the industrial revolution which caused two job cuts over the whole world. Nowadays, the bad influence may even worse. The mature assembly line work is controlled by automatic machine.Thereupon, a large amount of workers get unemployed. It is not benefit to stabilize society. Some of scientific inventions have also done great harms or disasters to mankind. And advanced technology can be easily manipulated by irresponsible persons or countriees.It is just easy to think of something, but difficult to give down-to-earth execution. We should avoid the negative effects while enjoying the great convenience. I believe that, once we try, we are bond to keep the balance of advantages and disadvantages.关于科技的英语演讲稿范文4The development of science and technology makes our life more comfortable and convenient.However, scientists have created many problems, which are not easy to be resolved,such as air pollution, the deterioration of environment and the scarcity of natural resources, to which we must some solutions. Modern science and technology render people many advantages. Modern telecommunication shortens the distance between people and makes communication much easier. Internet is widely used now not only for collection of abundant information but also for correspondence. Email, the most effective communication device now, is becoming very popular. Besides, telephone and mobile phone make contact more convenient than before. Modern transportation, such as airplanes and high-speed trains make our journey smooth and fast. With the help of modern transportation, people can go everywhere they prefer to. The journey to outer space and other planets is not a dream any more. Rocketsand space shuttles can help us realize the dream of space travel. Modern medicine prolongs peoples life and relieves patients of sufferings from many diseases. Cancer and AIDS are fatal to peoples health. Thanks to the endeavors scientists have made, these diseases become treatable. However, the process of scientific development also arouses many sever problems to our human beings. Internet, though widely used in modern communication, is easy to be destroyed by computer virus. Outer space exploration has produced much waste in the space. A tiny metal, a screw, for example can destroy a flying man-madesatellite.Industrialization is making natural resources become scarce. Confronted with these problems, scientists are seeking prompt and feasible solutions. The development of science and technology bring about both positive and negative effects to us. We must eliminate the positive effects to the least extent.关于科技的英语演讲稿范文5Science and art are the obverse and reverse of Nature's medal; the one expressing the eternal order of things, in terms of feeling, the other in terms of thought.Science has long had an uneasy relationship with other aspects of culture. Think of Galileo’s 17th-century trial for his rebelling belief before the Catholic church or poet William Blake’s harsh remarks against the mechanistic worldview of Isaac Newton. The schism between science and the humanities has, if anything, deepened in this century.Until recently the scientific community was so powerful that it could afford to ignore its critics--but no longer. As funding for science has declined, scientists have attacked “anti-science” in several books, notably Higher Superstition, by Paul R. Gross, a biologist at the University of Virginia, and Norman Levitt, a mathematician at Rutgers University; and The Demon-Haunted World, by Carl Sagan of Cornell University.Defenders of science have also voiced their concerns at meetings such as “The Flight from Science and Reason,” held in New York City in 1995, and “Science in the Age of (Mis) information,” which assembled last June near Buffalo.Anti-science clearly means different things to different people. Gross and Levitt find fault primari ly with sociologists, philosophers and other academics who have questioned science’s objectivity. Sagan is more concerned with those who believe in ghosts, creationism and other phenomena that contradict the scientific worldview.关于科技的英语演讲稿范文6You might never fail on the scale I did, but some failure in life is inevitable. It is impossible to live without failing at something, unless you live so cautiously that you might as well not have lived at all – in which case, you fail by default.Failure gave me an inner security that I had never attained by passing examinations. Failure taught me things about myself that I could have learned no other way. I discovered that I had a strong will, and more discipline than I had suspected; I also found out that I had friends whose value was truly above the price of rubies.The knowledge that you have emerged wiser and stronger from setbacks means that you are, ever after, secure in your ability to survive. You will never truly know yourself, or the strength of your relationships, until both have been tested by adversity. Such knowledge is a true gift, for all that it is painfully won, and it has been worth more than any qualification I ever earned.关于科技的英语演讲稿范文7I was given the job of escorting him back to the Underground Station afterwards, and this man whose life had been shattered by cruelty took my hand with exquisite courtesy, and wished me future happiness.And as long as I live I shall remember walking along an empty corridor and suddenly hearing, from behind a closed door, a scream of pain and horror such as I have never heard since. The door opened, and the researcher poked out her head and told me to run and make a hot drink for the young man sitting with her. She had just had to give him the news that in retaliati on for his own outspokenness against his country’s regime, his mother had been seized and executed.Every day of my working week in my early 20s I was reminded how incredibly fortunate I was, to live in a country with a democratically elected government, where legal representation and a public trial were the rights of everyone.Every day, I saw more evidence about the evils humankind will inflict on their fellow humans, to gain or maintain power. I began to have nightmares, literal nightmares, about some of the things I saw, heard, and read.And yet I also learned more about human goodness at Amnesty International than I had ever known before.关于科技的英语演讲稿范文8Now, I am not going to stand here and tell you that failure is fun. That period of my life was a dark one, and I had no idea that there was going to be what the press has since represented as a kind of fairy tale resolution. I had no idea then how far the tunnel extended, and for a long time, any light at the end of it was a hope rather than a reality.So why do I talk about the benefits of failure? Simply because failure meant a stripping away of the inessential. I stopped pretending to myself that I was anything other than what I was, and began to direct all my energy into finishing the only work that mattered to me. Had I really succeeded at anything else, I might never have found the determination to succeed in the one arena I believed I truly belonged. I was set free, because my greatest fear had been realised, and I was still alive, and I still had a daughter whom I adored, and I had an old typewriter and a big idea. And so rock bottom became the solid foundation on which I rebuilt my life.关于科技的英语演讲稿范文9Amnesty mobilises thousands of people who have never been tortured or imprisoned for their beliefs to act on behalf of those who have. The power of human empathy, leading to collective action, saves lives, and frees prisoners. Ordinary people, whose personal well-being and security are assured, join together in huge numbers to save people they do not know, and will never meet. My small participation in that process was one of the most humbling and inspiring experiences of my life.Unlike any other creature on this planet, humans can learn and understand, without having experienced. They can think themselv es into other people’s places.Of course, this is a power, like my brand of fictional magic, that is morally neutral. One might use such an ability to manipulate, or control, just as much as to understand or sympathise.And many prefer not to exercise their imaginations at all. They choose to remain comfortably within the bounds of their own experience, never troubling to wonder how it would feel to have been born other than they are. They can refuse to hear screams or to peer inside cages; they can close their minds and hearts to any suffering that does not touch them personally; they can refuse to know.I might be tempted to envy people who can live that way, except that I do not think they have any fewer nightmares than I do. Choosing to live in narrow spaces leads to a form of mental agoraphobia, and that brings its own terrors. I think the wilfully unimaginative see more monsters. They are often more afraid.What is more, those who choose not to empathise enable real monsters. For without ever committing an act of outright evil ourselves, we collude with it, through our own apathy.One of the many things I learned at the end of that Classics corridor down which I ventured at the age of 18, in search of something I could not then define, was this, written by the Greek author Plutarch: What we achieve inwardly will change outer reality.关于科技的英语演讲稿范文10So given a Time Turner, I would tell my 21-year-old self that personal happiness lies in knowing that life is not a check-list of acquisition or achievement. Your qualifications, your CV, are not your life, though you will meet many people of my age and older who confuse the two. Life is difficult, and complicated, and beyond anyone’s total control, and the humility to know that will enable you to survive its vicissitudes.Now you might think that I chose my second theme, the importance of imagination, because of the part it played in rebuilding my life, but that is not wholly so. Though I personally will defend the value of bedtime stories to my last gasp, I have learned to value imagination in a much broader sense. Imagination is not only the uniquely human capacity to envision that which is not, and therefore the fount of all invention and innovation. In its arguably most transformative and revelatory capacity, it is the power that enables us to empathise with humans whose experiences we have never shared.One of the greatest formative experiences of my life preceded Harry Potter, though it informed much of what I subsequently wrote in those books. This revelation came in the form of one of my earliest day jobs. Though I was sloping off to write stories during my lunch hours, I paid the rent in my early 20s by working at the African research department at Amnesty International’s headquarters in London.There in my little office I read hastily scribbled letters smuggled out of totalitarian regimes by men and women who were risking imprisonment to inform the outside world of what was happening to them. I saw photographs of those who had disappeared without trace, sent to Amnesty by their desperate families and friends. I read the testimony of torture victims and saw pictures of their injuries. I opened handwritten, eye-witness accounts of summary trials and executions, of kidnappings and rapes.Many of my co-workers were ex-political prisoners, people who had been displaced from their homes, or fled into exile, because they had the temerity to speak against their governments. Visitors to our offices included those who had come to give information, or to try and find out what had happened to those they had left behind.I shall never forget the African torture victim, a young man no older than I was at the time, who had become mentally ill after all he had endured in his homeland. He trembled uncontrollably as he spoke into a video camera about the brutality inflicted upon him. He was a foot taller than I was, and seemed as fragile as a child.关于科技的英语演讲稿范文。

关于科学的英语演讲稿 [篇2]Good morning, my dear teacher and classmates, my name is ****, from***** I am here today to talk about the topic: ‘Strong Spin-Orbit Splitting on Bi Surf-aces’. Before the topic ,I would like to introduce that ***** is located in Chinese economic and financial center of Shanghai, being one of the most prestigious universities in China and having two beautiful campuses. Welcome to visit our school.Now I will use the following four parts to introduce my topic: Firstly, TheBackground of Rashba Effect , secondly, Surf-ace Geometric Structure of Bismuth, then ,Surf-ace States on Low-index Surf-aces of Bismuth, finally, we will have the Conclusion.Rashba effect is a momentum-dependent splitting of spin bands in two-dimensional condensed matter systems similar to the splitting of particles and anti-particles in the Dirac Hamiltonian. The splitting is a combined effect of atomic spin-orbit coupling andasymmetry of the potential in the direction perpendicular to the two-dimensional plane. The possible use of this effect is for spintronics applications, spin-filter devices and quantum computing.Bi is a striking example of the possible difference between surf-ace and bulk material properties. Most importantly, the surf-aces are much better metals than the bulk due to the existence of electronic surf-ace states crossing the Fermi level. Here the Bi surf-aces were simulated by a 22 layer film embedded in vacuum., being confirmed byangleresolved photoemission (ARPES) investigations and first-principles calculations.Here we explain the Bi(111) surf-ace in figure shows surf-ace states of Bi(111) calculated without and with spin-orbit splitting included. The shaded areas show the projection of the bulk bands obtained without and with SOC and theirsuperposition. In the case without SOC, a parabolic surf-ace state is located around Γ in the non-relativistic energy gap. This surf-ace state bandgives rise to a hexagonal electron-like Fermi surf-ace element. When the SOC term is included in thecalculation it results in a spin-splitting of the surf-ace state in all directions and leaves it degenerate only at Γ and at M. Very close to Γ the relativistic surf-ace state bands are degenerate with bulk states and show less clear surf-ace character.A comparison to the experimental dispersion can therefore immediately reveal if the spin–orbit splitting picture is correct. Such a comparison is shown in Fig. 5. The figure shows the calculated and measured electronic structure in the vicinity of two high symmetry points on surf-aces of Bi(111), which is in good agreenment. We can see that the intensity of both surf-ace states strongly decreases close to Γ. This is most likely due to the overlap with the projected bulk band structure. The surf-ace states are no longer genuine surf-ace states but surf-ace resonances, which penetrate much more deeply into the crystal and give a lower photoemission intensity. Having inversion symmetry, this calculation yields two spin-degenerate bands near the Fermi energythat do not cross at Γ.In this picture, we can also see that both calculations of Bi(110) and Bi(100) surf-aces show the very steep dispersion of the bands close to the symmetry point which is characteristic for the strong SOC.In conclusion, strong Spin-Orbit Splitting on Bi Surf-aces is studied by first-principles calculations. The SOC term leads to a strong and anisotropic splitting of the surf-ace-state bands that profoundly modifies the dispersion of the surf-ace states and the surf-ace FS.Thank you for listening!关于科学的英语演讲稿 [篇3]the presence of students, ladies and teachers, everyone! i was prepared intervals of cloud today, in honor here entitled “technology and future” speech, i am very proud of both, but some unease. in recent years, we have seen our great motherland, the cause of the rapid development of technology, which allow me to a chinese i feel very proud. remember that long ago, cell phone use almost the only one, which is called, but a few years ago, cell phones has undergone great changes,not only look more beautiful, but also use more, you can use the phones to take pictures, meetings, internet, text messages, etc. a series of things that i their life more convenient, so i am more aware of the strength of the technology, but i am just a fledglings students, “technology” as the word also aware of the limited, i am unable to use some very difficult theory to elaborate technology xuanji, no right to work on their elders i can promise of the technology blueprint. but i am willing to use a student’s perspective to the imagine technology and the future.from genetic engineering “is a live princes” dream, nano-technology “- not washing your clothing,” promises; from artificial intelligence “will give you a cute robot dog” warm, transgenic technology “let people grow mouse ears” wonders. the new technology in the birth of a new technology that will let people wild with joy, because these new technologies is gradually improving our lives, let us learn more about ourselves. in the near term, china completed its first sars virus genome sequencing, sars is now the world’s largest recognized the dangers ofthe disease, but why not other countries completed first, and we just completed the countries? very si-mp-le, this illustrates that our country backward than others, worse than others, we look at the past, had just started a country’s reform and opening up to the current level of science and technology has lead a large country, our motherland experienced a number of ups and downs, how many difficulties and bumpy however, we still back all of the motherland, the motherland because we firmly believe that - not only technological change destiny, can change the future. for our generation, the general feeling of the community is a strong sense of competition, learning a foot down. science knowledge is the focus of our attention, albert einstein, and stephen hawking, bill gates is the star we have in mind, computer science, physics and chemistry of modern dynamic is constantly affect us. we have to understand the importance of technology, know that the technology universal.although technology to create a new life prospects soliciting thoughts, inspiring. however, the final analysis is that we rely on our common efforts to精品文档realize. , as the future construction of the backbone of our generation of young people shoulders the burden is not light, new opportunities are always accompanied risks and challenges, but we will not give up that easily, we use our youth to predecessors vowed: never live up to their predecessors of our hope.looking back at the history of civilization, anderson is the history of mankind against the darkness of ignorance, is the scientific lit a fire in the raging human soul of hope; technology support civilization, science and technology to create the future, but the future is in our hands. let us become knowledge explorers, let us unknown roaming on the road, let me use our creativity to the world we live a better place.11/ 11。
