发明不仅要提供前所未有的东西，而且要提供比以往技术更为先进的东西，即在原理、结构特别是功能效益上优于现有技术。发明总是既有继承又有创造，在一般情况下大都有先进性。一起来看看关于发明的英语演讲五篇，欢迎查阅!

i've al ways been rooted mybelief intelligence can make betterplace30年前，我和朋友保罗艾伦创办微软时，我们幻想实现“在 每个家庭、在每张办公桌上都有一台计算机”，这在大多数的计算机体积如同冰箱的尺寸的年代，听起来有点异想天开。但是我们相 信个人电脑将改变世界。今天看来果真如此。30 年后，我仍然象上七年级的时候那样为计算机而狂热着迷。
alwaysbee suppose mybelief intelligence can ma ke betterpl ace.我相信计算机是我们用来满足好奇心及发明创造的最神奇的.工具——有了它们的帮助，甚至是最聪明的人凭自身力量无法应对的难题都将迎刃而解。计算机已经改变了我们的学习方式，为全球各 地的孩子们开启了一扇通向大千世界知识的窗户。它可以帮我们围绕我们关注的事物建立“群”，让我们和那些对自己重要的人保持 密切联系，不管他们身处何方。
i've al ways been rooted mybelief intelligence can make betterplace就像我的朋友沃伦布非一样，我为每天都能做自己热爱的事情而感到无比幸运。他称之为“踢踏舞工作”。我在微软的工作永远充满挑战，但使我一直坚持“踢踏舞工作”的是我们向人们展示 某些新成果的那些时刻，当他们看到计算机能辨认笔迹、语音或者能存储值得保留一辈子的照片时就会赞不绝口：“我不敢相信个人 电脑竟如此万能”。但是，除了能用电脑做出很酷的事情之外，我们还能通过许多别的方式在工作中发挥自己的创造力和聪明才智， 以改善我们的世界。全球仍有许许多多的人连最基本的生存需求都未能解决。举例来说，每年仍有数以万计的人死于那些在发达国家 易于预防和治疗的疾病。
i've al ways been rooted mybel ief creativity canmake heworld etterplace.canre member, 我认为，我所拥有的大量财富也使我负有回馈社会的责任。我的妻子梅林达和我致力于为尽可能多的人改善健康和教育.

i've always been optimist mybelief power creativity intelligence cacanremember, 我为医药、教育，当然还有技术发展的诸多前景而欢欣鼓舞。我相信，凭借人类与生俱来的发明创造能力和不畏艰难、坚忍不拔的品格，在我的有生之年里我们将在所有这些领域都创造出可喜的成就

in modern life we have many inventions.thesemachines are very useful.theycan make things better and faster than people.a washing machine can help us washclothes.we have more time to do that we want to doduring this time.a printingmachine prints a lot of books,newspapers and other thingsqiickly.buses,bikes,cars,trains,planes and shipshelr us travel faster thanbefore.the compter is wonderful machine.it is one of the most importantinventions.today it is used in many ways.it can store innformations and work outmath problems millions of times faster than a person can.in a few years,thecomputer may touch the lives of everyone.even people in faraway villages.
I think the most important modern invention is the Internet. With theInternet, we can do many things. For example, we can shop, learn knowledge,listen to music, and watch movies online. The Internet makes the world smaller.We can meet and talk to friends and relatives far away without spending a lot ofmoney. We can also post our blogs online so our friends can know what we aredoing by visiting our websites like zuowendidai(Joozone). Internet makes ourlife more exciting and easier.
Hello,everybody !it is my great honor to be here to share my idea with you.Today,I will talk something about DREAM——A word that has changed the world.
“What do you think is the word that has really changed our world ”
When I was asked about this question for the first time ,without thinkingit too much ,a word flash into my mind ——DREAM ,D-R-E-A-M.People more or lessdream about different things ,to be a teacher ,a doctor ,a scientist ,abusinessman and so on .All these people who have dreams should be respected,because Dreams make the world go around .We grow great by our dreams.All bigmen are great dreamers in their youth.Everyone has a dream ,and everythingstarts as one’s daydream.
Martin Luther king had a dream.He desired for a future where blacks andwhites would coexist harmoniously as equals.By speaking the way he did,heeducated,he inspired,he informed not just the people there,but people throughoutAmerica and unborn generations.He pushed forward the pace of American blacksociety towards the racial equality .
Thomas Edison had a dream.He dreamed of a lamp that could be operated byelectricity,began where he stood to put his dream into action,and despite morethan ten thousand failures,he stood by that dream until he made it a physicalreality!And today,his dream lights up the world at night.
Walt Disney had a dream.This,in itself,wasn't unusual -- he was alwaysdreaming.He dreamed of making the first animated feature film,and of building anamusement park that parents could enjoy right along with their kids.Walt Disneyempowered his dream and today,Disneyland,Disney world and Disney theme parksattract around the world thrill millions of visitors each and every year.
John F.kennedy had a dream.He wanted to land a man on the moon and returnhim safely to earth so as to restore faith in the American way of life.JohnF.kennedy empowered his dream and 8 years later Neil Armstrong stepped on theface of the moon.The moon landing certainly gave Americans new foundconfidence.
Dream --- A word that has changed the world Yes ,I would say so ,wouldn’tyou
Youth is a special life relay station ,the growth with the worry ,the lifefeeling become aware happily with the dream ,collected a unique youth melody inhere .
We decide.We choose.And as we decide and choose,so are our lives formed.Inthe end,forming our own destiny is what ambition is about.And most importantly,You are the one you choose to be.
It is easy to waste our lives ,our days ,our minutes .It is easy to existthan living .So hold fast to your dreams,For if dreams die,life is abroken-winged bird,That cannot fly.Hold fast to your dreams,For when dreamsgo,life is a barren field,Frozen with snow.
Dear teachers and students：
Good morning / afternoon / evening! My name is Liu zi yuan. The title of myspeech is the relationship between creativity and imagination.
尊敬的老师、同学们大家早上/下午/晚上好!我叫刘子源。我演讲的题目是创造力和想象力之间的关系。
There is no creativity without imagination. With the development of thesociety, creativity becomes more and more important. People could not satisfywith ordinary life. So we need creativity to meet their requirements. We can seesignificance of the creativity from an example. The smart phone—iphone spreadall over the world. That was the creativity of The Apple Inc. It is obvious thatit will produce a bigger profit than common manufacturing. But, hao can weacquire creativity?
没有想象力就没有创造力。随着社会的发展，创造力变得越来越重要。人们已经不能满足于日常生活。所以我们需要不断的创新来满足他们的需求。通过一个例子我们可以知道创造力的意义。苹果智能手机的使用遍及全世界。这就是苹果公司的创新。很显然，这项创新产生了巨大的利润比起普通的制造业。但是我们怎样才能获得创造力?
I think the creativity roots in imagination. Albert Einstein said thatimagination is important than knowledge. Because we should creative a thing thatis never appeared, we need to image. Use all the things and information aroundus to think and then go to achieve it. Without the imagination of the Wrightbrothers , human could not complete the flying dreams. Without the imaginationof the Alexander Graham Bell, we could not hear the voice from a distance. Ifthe creativity can make the human progress, imagination will be the road tosuccess. Where the imagination come from? Knowledge ? Experience ? practice? Iconsider that all of them are indispensable. It is often said that knowledge ispower. So we should empower ourselves with knowledge. After that we need toobtain experience form. practice. These are the basis, and we must strengthenthem to extend our imagination.
我认为创造力扎根于想象力。爱因斯坦曾经说过，想象力远远比知识更重要。因为我们要创造一个事物，以前从没有出现过的，因此我们需要想象。利用我们周围所有的事物以及信息去想象，然后去完成它。没有莱特兄弟的想象力，人类就不能实现飞天的梦想;没有贝尔的想象力，我们就不能听到来自远方的声音。如果说创造力可以使人进步，那么想象力就是通向成功的道路。想象力来自哪里?知识?经验?还是实践?我觉得所有这些都是必不可少的。俗语有云：知识就是力量。所以我们首先应该用知识武装自己，然后我们需要从实践中获得经验。这些都是基础，我们必须用它们来扩展我们的思维。
As contemporary college students, we must shoulder the responsibility ofthe future of our motherland. What we need is not only the knowledge of thepast, but also is the innovation of a new field. Our thought can not be bound bythe old things. We should understand that an excellent nation is always full ofcreativity. So we must promote our imagination. There is no creativity withoutimagination. That’s all, thank you!
作为一个当代的大学生，我们需要肩负起祖国的未来。我不仅需要旧的知识，而且更要创新新的知识领域。我们的思想不能被旧知识所束缚。我们应该知道，一个优秀的民族永远是一个具有创新性的名族，所以我们必须提升我们的想象力。因为没有想象力就没有创造力。演讲完毕，谢谢大家!
