求一篇关于人工智能的演讲，不需要太长，作为课前演讲
人工智能的定义可以分为两部分，即“人工”和“智能”。
“人工”比较好理解，争议性也不大。
有时我们会要考虑什么是人力所能及制造的，或者人自身的智能程度有没有高到可以创造人工智能的地步，等等。
但总的来说，“人工系统”就是通常意义下的人工系统。
人工智能是包括十分广泛的科学，它由不同的领域组成，如机器学习，计算机视觉等等，总的说来，人工智能研究的一个主要目标是使机器能够胜任一些通常需要人类智能才能完成的复杂工作。
但不同的时代、不同的人对这种“复杂工作”的理解是不同的。

希望对您有帮助，有用请采纳，谢谢~Our common destiny “ We are made wise not by the recollections of the past but by our responsibility for the future” ----George Bernard Shaw China is faced with some enormous challenges as it enters the 21st century. In order to ensure the prosperity of our nation and its future generations we must confront and ultimately solve these challenges. Some of the more pressing issues facing China are universal. These include environmental degradation, over population and the effects of globalization. To overcome some of the things we need to implement include: Enhancing our scientific and industrial technologies in such areas as IT, Bio- tech, AI and Cybernetics. Further develop public infrastructure in under developed regions. Promote education reform at all levels. Introduce sustainable development initiatives. The implementation of free trade agreement between China and ASEAN. The benefit to China in introducing these initiatives will be significant and far-reaching. It is important to realize that these initiatives need to filter down through all elements of the society in China. For instance, cutting edge technologies and intellectual properties; the development of e-commerce based economy; an education system that encourages innovation and creativity; increased foreign investment; higher living standards; more efficient use of natural resources. It is important for us to realize these reforms are both essential and necessary. These will help China to fulfill its vast and unrealized potential on the world stage. It will also contribute more to a globalized world of the new century. As for the future our task is not to foresee but to enable. 我们的共同命运 “我们并不是靠回忆过去而变得睿智，我们之所以明智是由于我们有对未来的责任感”。
中国在迈向二十一世纪的同时，也面临着一些巨大的挑战，为了确保我国的繁荣及为子孙后代着想，我们必须面对挑战并最终从根本上解决它们。
一些中国即将面临的挑战迫切的问题是全球普遍存在的。
这些问题包括环境恶化，人口过剩及全球化的影响。
为了解决这些问题，我们需要实施以下措施： （1）提高并增强我们的科学及产业技术，如在信息技术产业，生物技术领域，人工智能以及神经机械学领域； （2）加快推动欠发达地区的公共设施建设； （3）促进不同层次的教育改革； （4）使可持续发展的观念深入人心； （5）推行中国与东南亚联盟的自由贸易协定。
中国将受益于积极主动的采取具有重要深远意义的措施。
认识到这些措施需要实施到中国社会的各个层面是重要的，从而带来广泛且深远的各种改善，如：边缘科技及知识产权；发展以电子商务为基础的经济； 一种鼓励发明与创造的教育体制；更多的外国投资； 更高的生活水平；更加有效的利用自然资源。
我们要意识到各项改革措施是根本的也是有必要的。
这些将会促进中国在世界舞台上实现其巨大且尚未实现的潜力。
这也将会对全球化的新世纪做出贡献。
至于未来，我们的任务不是去预知未来，而是努力去使其成为现实。

这一次，我想谈谈英语。
我的话题是我爱英语。
正如每个人所知，英语在今天十分重要。
它已经被应用到世界的各个角落。
它已经成为商业上最为通用的一门语言并广泛的用于国际贸易。
如果我们能说好英语，我们就有更多的机会成功。
因为越来越多的人注意到这一点，学英语的人数正在已很高的速度增长。
但是对我而言，我学英语不仅仅因为它的重要性以及它的实用性，更是因为我喜爱英语。
当我学英语时，我可以体会到一种不同的思维方式，它可以给我更多接触世界的空间。
当我读英语小说时，我能感受到不同于阅读翻译文的快乐。
当我说英语时，我可以感到自信。
当我写英语时，我能够感到不同于汉语的那种美……我爱英语，它给了我一个色彩斑斓的梦。
我希望有朝一日我可以畅游世界，用我流利的英语，我可以和世界各地的人交友。
我能看到许多的名胜。
我希望我能够到伦敦去，因为那里是英语的故乡。
我也希望用我流利的英语来将我们的名胜介绍给说英语的朋友，我希望他们可以像我们一样的爱我们的国家。
我知道，罗马不是一天筑成的。
（成功需要日积月累。
）我相信在持续不断的努力学习下，总有一天我可以拥有一口流利的英语。
如果你想被爱，你就应该学着去爱他人。
所以我相信我对英语的爱定将换来它对我的爱。
我相信总有一天我会实现我的梦
谢谢
caring for nature--overpopulation(关爱大自然)what is nature? its everything that exists in the world independently of people, such as pants and animals, earth and rocks, and the weather.now more and more people are focusing on the nature. it is no doubt that the nature is important to every human being. no nature, no life. because of the supplies of the nature, we have lived happily for a long time. and we started to gain every thing available from the nature. and this lasted so long a time. today, people have discovered that the nature around is getting worse and worse.what is threatening the nature? air and water pollution, overharvesting of plant and animal species, overpopulation and so on. overpopulation is the biggest source of pollution. lets take overpopulation as an example.what does overpopulation feel like? when we move slowly through the city in a tazi. when we enter a crowded slum district. when the temperature is high and when the air is thick with dust and smoke. the streets are crowded with people. the streets seem alive with people. people eating. people washing. people talking. people sleeping. people visiting each other, arguing and screaming. people relieving themselves. people pushing their hands through the taxi windows, begging. people leading animals. people, people, people, people. as we drive slowly through the crowd, sounding the taxis horn, the dust, heat, noise and cooking fires made it like a scene from hell! i admit, frightening.to the nature, overpopulation is a big problem. more people, more pollution. and the big population is threatening the nature every second.the rapid rise in world population is not creating problems only for the developing countries. the whole world faces the problem that raw materials are being used up at an increasing rate and food production can not keep up with the population increase. people in rich countries make the heaviest demands on the worlds resources, its food, fuel and land, and cause the most pollution. a baby born in the united states will use in his lifetime 30 times more of the worlds resources than a baby born in india. unless all the countries of the world take united action to deal with the population explosion there will be more and more people fighting for a share of less and less land, food and fuel, and the future will bring poverty, misery and war to us all.for most of the developing countries, it is a good idea to control the population growth. for example, china has carried out birth control for years. and this plan has a great effect on the world population.if the population continues to increase, if the air and water continue to be polluted, if we dont do something to protect wild-plant and wildlife species will be declining. species and biological communities have difficulty adapting to change. economic opportunities and the quality of life of future generations are also put at risk. by protecting nature, we protect ourselves.lets unite together, hand in hand we stand all across the land. we can make this world in which to live. hand in hand. control the population growth. take good care of our nature中学生英语演讲稿 Friendship 友谊Friendship Every one of us, rich or poor, should at least have one or two good friends. My friends will listen to me when I want to speak, will wipe my eyes when I cry, will take care of me when I am sick, and my friends will go together with me side by side through this journey of life. As students, we could share more time with our friends. The friendship in our young hearts is pure, fresh and simple. I often feel very lucky to have a lot of good friends. Especially when I had Justin as one of my best friends. Justin was my English teacher from the USA. I met him in 1996 when I was a student who could only speak very little English. Justin was a vivid young man with a bright smile on his face, and he always had his special way to make the class active and attractive. He taught us English by telling stories, playing games, singing songs, and even dancing. I could still remember very clearly that one afternoon when we fin-ished our class, we went to some other classes to sing songs for them, just like what people do in the states on Christmas Eve. It was so interesting and unforgettable. Justin was an excellent teacher, because he taught us not only how to study English well, but also the way to find out the beauty of the world and the way to be angels to others' lives. I know there was friendship and pure love in our hearts. Facing this valuable emotion neither nationality nor age was important, the real importance lay in faith, under-standing, and care. Justin is the best friend I have ever had, and I know I will cherish those days of staying together with him as the best part of my memory. Friendship is a kind of treasure in our lives. It is actually like a bottle of wine, the longer it is kept, the sweeter it will be. It is also like a cup of tea. When we are thirsty, it will be our best choice, but when we have enough time to enjoy ourselves, it is also the most fragrant drink. However, in this fast-developing modern society, the reality is not that. More and more people forget to enjoy the beauty of life and -the beauty of friendship. They work hard in order to gain a higher position, in the society and to earn more money for their work. Of course, we don't deny that it is important to find a bet-ter place in our lives, but we wish more and more people could pay a little more attention to themselves and their friends. All of us have to spare some time for personal lives. We have to find the chance to express our emotion and love. When staying with our friends, we can release ourselves completely. We can do whatever we want, we can laugh together, talk together, and even cry to-gether. I should say that being together with our best friends is the most wonderful moment of our lives. As we know, we would feel lonely if we didn't even have a friend. But it doesn't mean we could depend on our friends all the time. There is a famous motto saying that “A friend is like a quilt with cotton wadding, but the real thing that keeps you warm is your own temperature.” It is really true. We have to work hard together with our friends, encourage each other and help each other. When we receive love and friendship, we should repay as much as we can. Finally, let's pray together now that one day, all of us could find the person we want to find, and could enjoy a real beautiful friendship in our lives. Let's pray the flower of friendship be-tween our friends and us would always bloom brightly in our hearts
