hello, ladies and gentlemen. i’m angela zhang from class 4 grade 8. today, my topic is, “the shanghai world expo”.
first, i’ll say something about world expo history. as we know, the very first world expo, the great exhibition of 1851, took place in the crystal palace in london. uk. ever since then, the goals of world expos have been both high-minded as well as commercial. visitors are able to explore the world outside of their everyday experience—outside cultures, new scientific advancements, and new inventions. world expos have excited and inspired more and more people in the world.
on december3, xx, the bureau of international expositions (or call it bie) announced that shanghai will host expoxx. the bie had received bids from five cities to host expoxx. among the 5 nice cities, the bie chose shanghai at last! it’s really an exciting news for not only shanghainese, but also all of chinese people. here are some details about it.
look at this profile carefully. the title is “the xx world exposition ,shanghai, china ”. this is the logo.
and the theme is “better city., better life”.ok, let’s guess who is the image representative? yeah, you’re right, yao ming!
shanghai expo is the first comprehensive world expo held in a developing country. and it is also the first one that takes “the city” as its theme, hoping that it can push forward the city development and help bring about a better urban living environment, just like the theme: better city, better life.
i think, as a student in shanghai, we should learn to be a gentle person and keep good manners from now on. and try to practice english more in order to communicate with foreigners fluently in the near future. because, we’re a part of shanghai!

高科技无处不在
schoolmates:
when you look the lovable animated cartoon, plays is in a stew human's computer games, rides the fast train, is answering transoceanic telephone time, ......not only your might once realize the science the strength, the science changed this world, also changed our life, the science side us.
opens for the 20th century the grand chapters, not only we discovered the humanity to experience the blood and the fire baptism in these hundred years, has created the innumerable scientific miracles. 19th century france famous science fiction writer of fiction verne fictionalizing, at that time let the human be inconceivable, he fantasized moon landing travel, the airplane, the long-range gun and so on, all 11 became the reality in the 20th century. in the 21st century today, the high tech is ubiquitous.
as cross-century one generation, how posture should we adapt the new century by, the load get up the new century heavy burden? not only science and technology changing with each new day, causes the science to serve for the most advanced technique, also more and more many seeps to during ours daily life, this needs us who is in the young people time to deeply love the science, the study science. participation science and technology “five small” competition, reading science and technology books, caused me to understand many truths. the precise robot, does not use the fuel the automobile, the hypothesized soccer game, high tech information transmission and so on, each one vivid interesting phenomena, aroused me to explore the science the desire.
our each people all want to study the science, the dissemination civilization, while enjoys the new life, must create the new life, now, the technical product renewal speeds up unceasingly, the visible television, the computer surfer, the pacemaker, already did not calculate was fresh. vacuum cleaner invented which from 1901, to the artificial earth satellite, carried the human spaceship, the science and technology demonstrates the formidable strength in the different domain. electronic industry, communication technology daily popularization, nanotechnology, superconductivity material widespread application, soon one day, perhaps in yours dinner table, can appear likely bio-engineering foods and so on outer space green pepper, man-made beefsteak. studies the science and technology, is not merely in order to become the scientist, also is for can adapt the life, more has been able to become the new century the master, the load gets up the new century, is the national construction, makes the contribution for the human culture.
since new china had been established, our country's technical development progresses by leaps and bounds, the synthesized insulin, finishes a job plants, the hybrid rice again, explodes atomic bomb and hydrogen bomb, launch satellite and airship and so on, these technical achievement which focuses attention on the common people, reduced our country and the advanced countries science and technology disparity greatly, has poured into the vigor for our country's modernization. grandpa deng xiaoping said “the science and technology is the first productive forces”, indeed so, the science has inserted the wing for our motherland soaring. chairman mao zedong once said to the youth that, the world was you, also is we, but is your in the final analysis. this speech, has been full of the elders to our earnest expectation. if the elders have constructed the 20th century motherlands with the industrious work, that, we should by the knowledge, get up the new century heavy burden by the scientific load.
schoolmates, we are being at the growth developmental stage, the study science, lets us start since childhood. we must learn each kind of literacy class diligently, because this is all study foundation; at the same time, to each kind the popular science books, the publication which suits our elementary student to look, should better read some in the after school; also should begin to do each science small experiment, the small manufacture positively, writes the science small paper and so on, raises to the science interest. long this gets down, we can certainly deeply love the science, has the rich scientific knowledge. humanity's wisdom is infinite, regardless of is us's challenger number detonation, the whole world computer virus' promotion, always all cannot prevent humanity's advance in technology. “the knowledge is the strength”, bacon this sentence enjoys great popularity the maxim did not know had driven how many earnestly seeks the knowledge human. now, lets us also use it to encourage oneself, makes one to deeply love the science the new generation, the load gets up the new century heavy responsibility, for our motherland tomorrow, will compose a more magnificent poem!
thanks everybody.
同学们：
当你们看着可爱的动画片，玩着迷人的电脑游戏，坐上快速的列车，接听着越洋电话的时候，……你可曾意识到科学的力量，科学不仅改变了这个世界，也改变了我们的生活，科学就在我们身边。
翻开20世纪的壮丽篇章，我们发现人类在这百年中不仅经历了血与火的洗礼，更创造了无数科学奇迹。19世纪法国著名科幻小说家凡尔纳的虚构，当时让人不可思议，他所幻想的登月旅行、飞机、远射程炮等，在20世纪都一一成为现实。在21世纪的今天，高科技更是无处不在。
作为跨世纪的一代，我们又该以怎样的姿态去适应新世纪，担起新世纪的重担呢? 科学技术的日新月异，使得科学不只为尖端技术服务，也越来越多地渗透到我们的日常生活之中，这就需要正处于青少年时代的我们热爱科学，学习科学。参加科技“五小”比赛、阅读科技书籍，使我明白了许多道理。精密的机器人，不用燃料的汽车，虚拟的足球赛，高科技信息的传送等等，一个个生动有趣的现象，激起了我探索科学的愿望。
我们每个人都要学习科学，传播文明，在享受新生活的同时，更要创造新生活，如今，科技产品的更新换代不断加快，可视电视、电脑上网、心脏起搏器，已经不算新鲜了。从19xx年发明的真空吸尘器，到人造地球卫星、载人宇宙飞船，科技在不同领域里显示出了强大的力量。电子产业、通讯技术的日益普及，纳米技术、超导材料的广泛应用，不久的一天，也许就在你的餐桌上，会出现像太空青椒、人造牛排等生物工程食品。学习科学技术，不仅仅是为了成为科学家，也是为了能适应生活，更为了能成为新世纪的主人，担起新世纪，为国家建设，为人类文明做出贡献。
新中国成立以来，我国的科技发展突飞猛进，人工合成胰岛素、断手再植、杂交水稻、爆炸原子弹和氢弹、发射人造卫星和飞船等等，这些令世人瞩目的科技成就，大大缩短了我国和先进国家的科学技术的差距，为我国的现代化建设注入了活力。邓小平爷爷说“科学技术是第一生产力”，的确如此，科学为我们祖国的腾飞插上了翅膀。毛泽东主席曾对青年说，世界是你们的，也是我们的，但归根结底是你们的。这句话，饱含了长辈们对我们的殷切期望。如果说长辈们用辛勤的劳动建设了20世纪的祖国，那么，我们就应该以知识、以科学担起新世纪的重担。
同学们，我们正处于成长发育阶段，学习科学，让我们从小做起。我们要努力学好各种文化课，因为这是一切学习的基础;同时，对各种适合我们小学生看的科普书籍、报刊，最好在课余多阅读一些;还应该积极动手搞各种科学小实验、小制作，写科学小论文等，培养对科学的兴趣。长此下去，我们一定能够热爱科学，拥有丰富的科学知识。 人类的智慧是无限的，无论是美国的挑战者号爆炸，还是全球计算机病毒的升级，从来都不能阻止人类的科技进步。“知识就是力量”，培根这句脍炙人口的格言不知激励了多少渴求知识的人。如今，让我们也用它来勉励自己，做一个热爱科学的新一代，担起新世纪的重任，为我们祖国的明天，谱写出更加辉煌的诗篇!
谢谢大家!
