1、关于科技的英文演讲稿关于科技的英文演讲稿篇一：科技与未来英语演讲The development of science and technology makes our life more comfortable and , 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 som

2、e 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 effect

3、ive 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

4、 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

5、 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 p

6、roduced much waste in the space. A tiny metal, a screw, for example can destroy a flying man-made 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 n

7、egative effects to us. We must eliminate the positive effects to the least extent.篇二：英语演讲稿科技关于科技的英语演讲稿technology and future the presence of students, ladies and teachers, everyone! i was prepared intervalsof cloud today, in honor here entitled technology and future speech, i am very proudof both, bu

12、nd bumpyhowever, we still back all of the motherland, the motherland because we firmly believethat - not only technological change destiny, can change the , but we will not give up that easily, we use our youth to predecessorsvowed: never live up to their predecessors of our hope. looking back at th

13、e historyof civilization, anderson is the history of mankind against the darkness of ignorance,is the参考翻译：在场的学生们，女士们，老师，大家好！我准备间隔云今天，为了纪念在这里题为“科技与未来”的讲话，我感到非常自豪的两个，但有些不安。近年来，我们已经看到我们伟大的祖国，事业的迅速发展，技术，请允许我向中国我感到非常自豪。请记住，很久以前，手机应用几乎只有一个，这是所谓的，但在几年前，手机发生了很大变化，不仅看起来更漂亮，而且还更多地使用，您可以使用手机拍照，会议上，互联，短信等一系列的事情

14、，我的生活更方便，所以我更多地了解的力量，技术，但我只是一个幼鸟学生， “技术”作为也知道这个词的有限，我无法使用一些非常困难的理论阐述技术xuanji ，没有权利对他们的长辈的工作我可以保证的技术蓝图。但我愿意利用学生的观点，以创新技术和未来。从基因工程“是一个生活王子”的梦想，纳米技术“不洗你的衣服， ”承诺，从人工智能“会给你一个可爱的机器狗”热情，转基因技术“让人们增长鼠标耳朵”奇观。这项新技术的诞生，一种新技术，将让人们欣喜若狂，因为这些新技术正在逐步改善我们的生活，让我们更多地了解自己。在近期内，中国完成了其第一个sars病毒基因组测序， sars是目前世界上最大的承认危险的疾病，

15、但我们为什么不把其他国家完成第一次，我们刚刚完成的国家？很简单，这说明我们的国家比其他国家落后，不如别人，我们回顾过去，刚刚开始了一个国家的改革开放和当前的科技水平已经导致一个大国，我们的祖国经历了一些的跌宕起伏，有多少困难和坎坷，但我们仍然回到所有的祖国，祖国，因为我们坚信， -不仅是技术变革的命运，可以改变未来。我们这代人，一般感情的社会是一个强烈的竞争，学习一英尺下降。科学知识是我们关注的焦点，爱因斯坦，和斯蒂芬霍金，比尔盖茨是明星我们想到，计算机科学，物理学和化学的现代活力正在不断影响着我们。我们必须理解技术的重要性，知道该技术具有普遍性。虽然技术创建一个新的生活前景征求思想，鼓舞人心

16、的。然而，归根结底是要靠我们共同的努力，以实现。作为未来建设的骨干，我们这一代年轻人肩上的负担并不轻，新的机遇总是伴随的风险和挑战，但我们不会轻易放弃，我们用我们的青年前任誓言：决不辜负他们的前辈，我们的希望。回首文明史上，安德森是人类历史上的黑暗的无知，是科学点燃了大火在肆虐人类灵魂的希望；技术支持文明，科学和技术，创造未来，但未来在我们的手中。让我们成为知识的探索者，让我们未知的道路上漫游，让我用我们的创造力，我们生活的世界变得更美好。of cloud today, in honor here entitled technology and future speech, i am very

20、c: firstly, the background of rashba effect , secondly, surface geometric structure of bismuth,then ,surface states on low-index surfaces of bismuth, finally, we will have theconclusion.bi is a striking example of the possible difference between surface and bulkmaterial properties. most importantly,

21、 the surfaces are much better metals than thebulk due to the existence of electronic surface states crossing the fermi level. herethe bi surfaces were simulated by a 22 layer film embedded in vacuum., being confirmedbyangleresolved photoemission (arpes) investigations and first-principlescalculation

22、s.here we explain the bi(111) surface in figure shows surface statesof bi(111) calculated without and with spin-orbit splitting included. the shadedareas show the projection of the bulk bands obtained without and with soc and theirsuperposition. in the case without soc, a parabolic surface state is

23、locatedaround in the non-relativistic energy gap. this surface state band gives rise toa hexagonal electron-like fermi surface element. when the soc term is included inthecalculation it results in a spin-splitting of the surface state in all directionsand leaves it degenerate only at and at m. very

24、close to the relativisticsurface state bands are degenerate with bulk states and show less clear surfacecharacter. that do not cross at . in this picture, we can also see that both calculations of bi(110) and bi(100)surfaces show the very steep dispersion of the bands close to the symmetry point whi

25、chis characteristic for the strong soc. in conclusion, strong spin-orbit splitting on bi surfaces is studied byfirst-principles soc term leads to a strong and anisotropic splitting of the surface-statebands that profoundly modifies the dispersion of the surface states and the surfacefs.thank you for

26、 listening!篇四：英文演讲稿i have been in university for about one year. during my stay here, i came to realizethat university life is like drinking coke. we experience all tastes of life here,sour, sweet, bitter and hot. lucky for me, life in university is rich and colorful. with more free time,wecan do ma

27、ny more things besides study, such as joining societies clubs, and takingpart-time jobs. such activities not only make our life more colorful, but also helpus improve all kinds of skills. the university is a society miniature, what we learnhere will benefit our future life. university life is like d

28、rinking coke. im experiencing it. and i know, i enjoyit! 我一直在大学呆了一年多。我在这儿时,我才意识到大学生活就像喝可乐。我们的生活经历各种口味、酸、甜、苦、辣。 我从省,离这儿很远。我常常想念妈妈的亲戚、朋友,在我的家乡。然而,我不能经常见到他们。那么孤独总是会陪伴我。我很难过,我无法和他们在一起。 幸运的是,我在大学生活是丰富多彩的。有更多的闲暇时间,我们可以做更多的事情除了学习,如加入社团俱乐部,打工。这样的活动,不仅使我们的生活更加丰富多彩,而且还能帮助我们改进各种各样的技能。大学是一个社会,我们在这里学到的微缩有利于我们今后的

29、生活。我们的人生之路不会一帆风顺。挫折是无法避免的。失败的一个重要的考试,跟男孩还是女孩的朋友,或者拒绝由一个有前途的公司,这样可能会让我们的挫折。有时候,我们觉得很沮丧,我们甚至大哭起来。 喝可乐是美妙的,尽管undesirble随之打嗝。这是苦的,酸和暴躁,而且甜。你甚至可以感觉到激动下一杯。全身后,一个大学的经验是成长的一部分。我们哭泣,微笑着,坠入爱河,受伤,离开,学习,然后我们做一个更好的人。 大学生活就像喝可乐。我的感受。我知道,我喜欢它!youthyouth is not a time of life; it is a state of mind; it is not a mat

30、ter of rosycheeks, red lips and supple knees; it is a matter of the will, a quality of theimagination, a vigor of the emotions; it is the freshness of the deep springs of means a temperamental predominance of courage over timidity of the appetite,for adventure over the love of ease. this often exist

31、s in a man of sixty more thana body of twenty. nobody grows old merely by a number of years. we grow old bydeserting our ideals. years may wrinkle the skin, but to give up enthusiasm wrinkles the soul. worry,fear, self-distrust bows the heart and turns the spirit back to dust. whether sixty or sixteen, there is in every human beings heart the lure of wonder,the unfailing child-like appetite of whats next, and the joy of the game of living.in the center of your heart and my heart there is a wireless station; so long as it
