i have the answer to a question that we've all asked. the question is, why is it that the letter x represents the unknown? now i know we learned that in math class, but now it's everywhere in the culture -- the x prize, the x-files, project x, tedx. where'd that come from?
about six years ago i decided that i would learn arabic, which turns out to be a supremely logical language. to write a word or a phrase or a sentence in arabic is like crafting an equation, because every part is extremely precise and carries a lot of information. that's one of the reasons so much of what we've come to think of as western science and mathematics and engineering was really worked out in the first few centuries of the common era by the persians and the arabs and the turks.
this includes the little system in arabic called al-jebra. and al-jebr roughly translates to “the system for reconciling disparate parts.“ al-jebr finally came into english as algebra. one example among many.
the arabic texts containing this mathematical wisdom finally made their way to europe -- which is to say spain -- in the 11th and 12th centuries. and when they arrived there was tremendous interest in translating this wisdom into a european language.
but there were problems. one problem is there are some sounds in arabic that just don't make it through a european voice box without lots of practice. trust me on that one. also, those very sounds tend not to be represented by the characters that are available in european languages.
here's one of the culprits. this is the letter sheen, and it makes the sound we think of as sh -- “sh.“ it's also the very first letter of the word shalan, which means “something“ just like the the english word “something“ -- some undefined, unknown thing.
now in arabic, we can make this definite by adding the definite article “al.“ so this is al-shalan -- the unknown thing. and this is a word that appears throughout early mathematics, such as this 10th century derivation of proofs.
DREAM——A word that has changed the world
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 thinking it too much ,a word flash into my mind ——DREAM ,D-R-E-A-M.People more or less dream about different things ,to be a teacher ,a doctor ,a scientist ,a businessman 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 big men are great dreamers in their youth.Everyone has a dream ,and everything starts as one’s daydream.
Martin Luther king had a dream.He desired for a future where blacks and whites would coexist harmoniously as equals.By speaking the way he did,he educated,he inspired,he informed not just the people there,but people throughout America and unborn generations.He pushed forward the pace of American black society towards the racial equality .
Thomas Edison had a dream.He dreamed of a lamp that could be operated by electricity,began where he stood to put his dream into action,and despite more than ten thousand failures,he stood by that dream until he made it a physical reality!And today,his dream lights up the world at night.
Walt Disney had a dream.This,in itself,wasn't unusual -- he was always dreaming.He dreamed of making the first animated feature film,and of building an amusement park that parents could enjoy right along with their kids.Walt Disney empowered his dream and today,Disneyland,Disney world and Disney theme parks attract 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 return him safely to earth so as to restore faith in the American way of life.John F.kennedy empowered his dream and 8 years later Neil Armstrong stepped on the face of the moon.The moon landing certainly gave Americans new found confidence.
Dream --- A word that has changed the world Yes ,I would say so ,wouldn’t you
Youth is a special life relay station ,the growth with the worry ,the life feeling become aware happily with the dream ,collected a unique youth melody in here .
We decide.We choose.And as we decide and choose,so are our lives formed.In the 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 exist than living .So hold fast to your dreams,For if dreams die,life is a broken-winged bird,That cannot fly.Hold fast to your dreams,For when dreams go,life is a barren field,Frozen with snow.
I hope you everyone he
NO IMAGINATION, NO CREATIVITY
Dear teachers and students：
Good morning / afternoon / evening! My name is Liu zi yuan. The title of my speech is the relationship between creativity and imagination.
There is no creativity without imagination. With the development of the society, creativity becomes more and more important. People could not satisfy with ordinary life. So we need creativity to meet their requirements. We can see significance of the creativity from an example. The smart phone—iphone spread all over the world. That was the creativity of The Apple Inc. It is obvious that it will produce a bigger profit than common manufacturing. But, hao can we acquire creativity?
I think the creativity roots in imagination. Albert Einstein said that imagination is important than knowledge. Because we should creative a thing that is never appeared, we need to image. Use all the things and information around us to think and then go to achieve it. Without the imagination of the Wright brothers , human could not complete the flying dreams. Without the imagination of the Alexander Graham Bell, we could not hear the voice from a distance. If the creativity can make the human progress, imagination will be the road to success. Where the imagination come from? Knowledge ? Experience ? practice? I consider that all of them are indispensable. It is often said that knowledge is power. So we should empower ourselves with knowledge. After that we need to obtain experience form. practice. These are the basis, and we must strengthen them to extend our imagination.
As contemporary college students, we must shoulder the responsibility of the future of our motherland. What we need is not only the knowledge of the past, but also is the innovation of a new field. Our thought can not be bound by the old things. We should understand that an excellent nation is always full of creativity. So we must promote our imagination. There is no creativity without imagination. That’s all, thank you!
ladies and gentlemen, honorable judges, good afternoon.

Here are the beacon tower, also known as beacons, Wolf yantai. Independent buildings is not connected to the Great Wall. Once the enemy pounce, communicate its kindle wars and light smoke during the day is called "ran, called flint fire at night. When the Ming dynasty, also on the relationship between the war with the enemy made a strict rules: the enemy hundreds, burning a smoke point a gun; Five hundred people, burning two smoke point two guns; More than one thousand people, three smoke SAN pao; More than five thousand people, four smoke four guns; More than ten thousand people, five five gun smoke. In this way, on the border of the military intelligence can rapid transfer to the imperial city ouchi. See the beacon tower, and then tell you a story, called "must play leud" : the zhou dynasty had a king named weeks you king, he has a beautiful woman, her temper is very strange, always don't smile, think of some way to you king. He lit up a distress signal (fire), as a result, drew leud come white, she laughed, you king is also very happy. But, really have an enemy to attack, you king lit the fire, but no one come, and he was killed by the enemy. There is a story, called "meng jiangnu cry Great Wall collapse" : legend was Meng Gusheng a daughter named meng jiangnu. Because of qin shi huang to build the Great Wall, need a lot of manpower. Qin shi huang was caught many people go to the Great Wall.
All of a sudden, I do not know where to come up to a rumor: only the wan xi is buried under the Great Wall, can make the Great Wall and solid, qin shi huang was, sent people seize wan xi. Wan xi good fled to Bangladesh. People see wan xi meng home good handsome, talented, good let meng jiangnu and wan xi of their marriage. The two men marry less than 10 days, good wan xi is the rulers who grasp to go to repair the Great Wall. In the fall, meng jiangnu saw her husband hasn't come back, give him the woolies. Along the way, reject, hardships, day and night, all the way to the Great Wall. Local people told her: wan xi good would have buried under the wall. She was grief-stricken, crying. Instantly, and dark, the Great Wall was crying collapsed in eight hundred. Just then, qin shi huang to have the Great Wall, with fine features, when he saw meng jiangnu just want her to do concubine. For qin shi huang meng jiangnu agree to her three conditions: one is for wan xi is a grave; The second is to make good full chao wenwu festivals wan xi; Three is in the middle of the Great Wall and the tomb of wan xi good repair a like flying grand bridge. After three things done, she threw herself into the sea.
this is no surprise though if you look at the insights of contemporary psychology. it turns out that we can't even be in a group of people without instinctively mirroring, mimicking their opinions. even about seemingly personal and visceral things like who you're attracted to, you will start aping the beliefs of the people around you without even realizing that that's what you're doing.
and groups famously follow the opinions of the most dominant or charismatic person in the room, even though there's zero correlation between being the best talker and having the best ideas -- i mean zero. so ... (laughter) you might be following the person with the best ideas, but you might not. and do you really want to leave it up to chance? much better for everybody to go off by themselves, generate their own ideas freed from the distortions of group dynamics, and then come together as a team to talk them through in a well-managed environment and take it from there.
now if all this is true, then why are we getting it so wrong? why are we setting up our schools this way and our workplaces? and why are we making these introverts feel so guilty about wanting to just go off by themselves some of the time? one answer lies deep in our cultural history. western societies, and in particular the u.s., have always favored the man of action over the man of contemplation and “man“ of contemplation. but in america's early days, we lived in what historians call a culture of character, where we still, at that point, valued people for their inner selves and their moral rectitude. and if you look at the self-help books from this era, they all had titles with things like “character, the grandest thing in the world.“ and they featured role models like abraham lincoln who was praised for being modest and unassuming. ralph waldo emerson called him “a man who does not offend by superiority.“
but then we hit the 20th century and we entered a new culture that historians call the culture of personality. what happened is we had evolved an agricultural economy to a world of big business. and so suddenly people are moving from small towns to the cities. and instead of working alongside people they've known all their lives, now they are having to prove themselves in a crowd of strangers. so, quite understandably, qualities like magnetism and charisma suddenly come to seem really important. and sure enough, the self-help books change to meet these new needs and they start to have names like “how to win friends and influence people.“ and they feature as their role models really great salesmen. so that's the world we're living in today. that's our cultural inheritance.

when i was nine years old i went off to summer camp for the first time. and my mother packed me a suitcase full of books, which to me seemed like a perfectly natural thing to do. because in my family, reading was the primary group activity. and this might sound antisocial to you, but for us it was really just a different way of being social. you have the animal warmth of your family sitting right next to you, but you are also free to go roaming around the adventureland inside your own mind. and i had this idea that camp was going to be just like this, but better. (laughter) i had a vision of 10 girls sitting in a cabin cozily reading books in their matching nightgowns.
(laughter)
camp was more like a keg party without any alcohol. and on the very first day our counselor gathered us all together and she taught us a cheer that she said we would be doing every day for the rest of the summer to instill camp spirit. and it went like this: “r-o-w-d-i-e, that's the way we spell rowdie. rowdie, rowdie, let's get rowdie.“ yeah. so i couldn't figure out for the life of me why we were supposed to be so rowdy, or why we had to spell this word incorrectly. (laughter) but i recited a cheer. i recited a cheer along with everybody else. i did my best. and i just waited for the time that i could go off and read my books.
but the first time that i took my book out of my suitcase, the coolest girl in the bunk came up to me and she asked me, “why are you being so mellow?“ -- mellow, of course, being the exact opposite of r-o-w-d-i-e. and then the second time i tried it, the counselor came up to me with a concerned expression on her face and she repeated the point about camp spirit and said we should all work very hard to be outgoing.
and so i put my books away, back in their suitcase, and i put them under my bed, and there they stayed for the rest of the summer. and i felt kind of guilty about this. i felt as if the books needed me somehow, and they were calling out to me and i was forsaking them. but i did forsake them and i didn't open that suitcase again until i was back home with my family at the end of the summer.
now, i tell you this story about summer camp. i could have told you 50 others just like it -- all the times that i got the message that somehow my quiet and introverted style of being was not necessarily the right way to go, that i should be trying to pass as more of an extrovert. and i always sensed deep down that this was wrong and that introverts were pretty excellent just as they were. but for years i denied this intuition, and so i became a wall street lawyer, of all things, instead of the writer that i had always longed to be -- partly because i needed to prove to myself that i could be bold and assertive too. and i was always going off to crowded bars when i really would have preferred to just have a nice dinner with friends. and i made these self-negating choices so reflexively, that i wasn't even aware that i was making them.
now this is what many introverts do, and it's our loss for sure, but it is also our colleagues' loss and our communities' loss. and at the risk of sounding grandiose, it is the world's loss. because when it comes to creativity and to leadership, we need introverts doing what they do best. a third to a half of the population are introverts -- a third to a half. so that's one out of every two or three people you know. so even if you're an extrovert yourself, i'm talking about your coworkers and your spouses and your children and the person sitting next to you right now -- all of them subject to this bias that is pretty deep and real in our society. we all internalize it from a very early age without even having a language for what we're doing.
Everyone tries to achieve success in his/her career. But some finally attain their aims while others fail. Why? Some continue their cause to the end through long period of hard struggles， but others are easily disappointed and stop halfway.
Strong will， perseverance and diligence are the three essentials of success. A man of strong will and perseverance always has an inflexible spirit. He sticks to his cause no matter how tough it might be. Life is short and we have too much to do. Without diligence no one can achieve anything.
I believe that where there is a will there is a way， and that success belongs to those who can make constant efforts.
Don't be afraid of life. Believe that life is worth living， and your belief will help create the fact.
the vast, the unbounded prospect lies before us.
death. old age. are words without a meaning. that paby us like the idea air which we regard not. others may have undergone, or may still be liable to them-we "bear a charmed life“, which laughs to scorn all such sickly fancies. as in setting out on delightful journey, we strain our eager gaze forward-
bidding the lovely scenes at distance hail!
and see no end to the landscape, new objects presenting themselves as we advance; so, in the commencement of life, we set no bounds to our inclinations. nor to the unrestricted opportunities of gratifying them. we have as yet found no obstacle, no disposition to flag; and it seems that we can go on so forever. we look round in a new world, full of life, and motion, and ceaseleprogress; and feel in ourselves all the vigor and spirit to keep pace with it, and do not foresee from any present symptoms how we shall be left behind in the natural course of things, decline into old age, and drop into the grave. it is the simplicity, and as it were abstractedneof our feelings in youth, that (so to speak) identifies us with nature, and (our experience being slight and our passions strong) deludes us into a belief of being immortal like it. our short-lives connection with existence we fondly flatter ourselves, is an indissoluble and lasting union-a honeymoon that knows neither coldness, jar, nor separation. as infants smile and sleep, we are rocked in the cradle of our wayward fancies, and lulled into security by the roar of the universe around us0we quaff the cup of life with eager haste without draining it, instead of which it only overflows the more-objects prearound us, filling the mind with their magnitude and with the strong of desires that wait upon them, so that we have no room for the thoughts of death.
As we all know，the environmemt around us is getting worse and worse .In someplaces，we can't see fish swimming in the river or trees on the hills. Some people even have noclean water to drink. So I think we must do something to protect the environment. But whatcan we do?How to protect our environmemt ?
For example，we can go to school on foot or bybike . we can use shopping baskets not plastic bags when we go shopping，and we can useboth sides of the paper when we write .In a word，if everyone pays more attention to ourenvironment ，there will be less pollution and our life will be better。“There is only oneearth”，I hope everyone will protect our environment well。
勤练习。
即便是优秀的演讲者都会事先练习他们的演讲。用录音机或是摄像机将整个练习的过程记录下来，这样你就可以了解自己的表现从而发现哪些地方可以改进。如果你够勇敢的话，你也可以在朋友或是家人的面前练习，并向他们征求意见。
Dream, everybody has. However, I think, the dream as the growth of the age, will change at any time!
The dream of the age of three
When I was 3 years old, although also just a girl, but, we also have a 3 years old dream! My dream is to every day can eat to the color seductive jelly beans! The kindergarten every day, dad and creak on his bicycle to pick me up, I will think, dad today will certainly bring color jelly beans to pick me up. But, want to return to, dad didn't often bring me eat jelly beans. At that time, I will run to dad's arms, with a peevish tone to dad said: "dad, are you to buy me some color jelly beans?" Father seems a little angry: "oh, don't buy, not buy, jelly beans to eat many will have decayed tooth!" I still don't give up: "I'm not eat every day, you can buy!" Sometimes, after my request for a long time, father finally agreed to me, I am happy to eat a dream at the age of 3, fruity! The food is delicious.
At the age of 8 dream
At the age of eight, I had been sitting in the third grade. Said dream, also won't go to jelly beans. At that time, I am addicted to reading.
Mother and I went to a backgammon supermarket, I entered the house, left flip, flip right, when turn to a book - the story character, I carefully looked up, I could see them forget all about eating and sleeping, even my mother told me to go home, I did not hear. Aunt until the store is closed, when I go home, I was pleased. After that, I often go to read a book, of course, I have mastered a lot of writing skills. The teacher also to me a thumbs-up! The book gives me knowledge and fun.
Dream at the age of 11
At the age of 11, I was in the sixth grade, my dream is as bigger, my dream is to enter key middle school at 1 or 4. Had the goal, to work harder. I write my homework every day, the remedial class around in my side every day, although very hard, very tired, but I still insist on, don't be difficult tripping, strive to succeed.
Because the dream with my growth, let me track on the road to success.
Knowing the Consequences of Choice
Over the past Spring Festival, I got involved in a family dispute. Right before I got home, four satellite channels of CCTV were added to the 14 channels we had already had. In prime time at night, they all had interesting shows. Therefore, the five of us-my parents, my sisters and I-had to argue over what to watch. Finally, we agreed that we should watch the "most interesting" programme... If we
could agree what that was.
However, all of us there remember that for a long time after we had TV, there were only one or two channels available. The increase in options reveals an important change in our life: the abundance of choice.
Fifteen years ago we all dressed in one style and in one colour. Today, we select from a wide variety of designs and shades.
Fifteen years ago, we read few newspapers. Today, we read English newspapers like the China Daily and the 21st Century, as well as various Chinese newspapers.
Fifteen years ago, English majors took only courses in language and literature. Today, we also study Western culture, journalism, business communications, international relations, and computer science.
The emergence of choices marks the beginning of a new era in China's history; an era of diversity, of material and cultural richness, and an era of the rebirth of the Chinese nation. We enjoy the abundance of choice. But this has not come easily.
About 150 years ago, China was forced to open up its door by Western canons and gunboats. It has been through the struggle and sacrifice of generations that we finally have gained the opportunity to choose for ourselves. The policy of reform and openness is the choice that has made all the difference.
Like others of my age, I'm too young to have experienced the time when the Chinese people had no right to choose. However, as the next century draws near, it is time to ask: What does choice really mean to us young people?
Is choice a game that relies on chance or luck? Is choice an empty promise that never materializes? Or is choice a puzzle so difficult that we have to avoid it?
First, I would like to say: To choose means to claim opportunities.
I am a third-year English major. An important choice for me, of course, is what to do upon graduation. I can go to graduate school, at home or abroad. I can go to work as a teacher, a translator, a journalist, an editor and a diplomat. Actually, the system of mutual selection has allowed me to approach almost every career opportunity in China.
Indeed, this is not going to be an easy choice. I would love to work in such big cities as Beijing or Shanghai or Shenzhen. I would also love to return to my hometown, which is intimate, though slightly lagging in development. I would love to stay in the coastal area where life is exciting and fast-paced. I would also love to put down roots in central and western China, which is underdeveloped, but holds great potential.
All of these sound good. But they are only possibilities. To those of us who are bewildered at the abundance of opportunities, I would like to say: To choose means to accept challenge. To us young people, challenge often emerges in the form of competition. In the next century, competition will not only come from other college graduates, but also from people of all ages and of all origins.
With increasing international exchanges, we have to face growing competition from the whole outside world. This is calling for a higher level of our personal development.
Fifteen years ago, the knowledge of a foreign language or of computer operation was considered merely an advantage. But today, with wider educational opportunities, this same knowledge has become essential to everyone.
Given this situation, even our smallest choices will require great wisdom and personal determination.
As we gain more initiative in choice making, the consequence of each choice also becomes more important.
As we gain more initiative in choice making, the consequence of each choice also becomes more important.
Nuclear power, for instance, may improve our quality of life. But it can also be used to damage the lives and possessions of millions.
Economic development has enriched our lives but brought with it serious harm to our air, water and health.
To those of us who are blind to the consequences of their choices, I would like to say, To choose means to take responsibility. When we are making choices for ourselves, we cannot casually say: "It's just my own business. " As policy makers of the next century, we cannot fail to see our responsibility to those who share the earth with us.
The traditional Chinese culture teaches us to study hard and work hard so as to honor our family. To me, however, this family is not just the five of us who quarreled over television programmes. Rather, it is the whole of the human family. As I am making my choices, I will not forget the smile of my teacher when I correctly spelled out the word "China" for the first time, I will not forget the happy faces of the boys and girls we helped to send back to school in the mountains of Jiangxi Province. I will not forget the tearful eyes of women and children in Bosnia, Chechnya and Somali, where millions are suffering from war, famine or poverty. All these people, known and unknown, make up our big human family. At different points, they came into my life and broaden my perspective. Now as I am to make choices for myself, it is time to make efforts to improve their lives, because a world will benefit us all only if every one in it can lead a peaceful and prosperous life.
选择的重要性
去年春节期间，我陷入过一场家庭纷争。在我回家之前，我们家的电视除了已有的14个频道外又增加了四个卫星频道。晚上的黄金时间，每个频道的节目都很精彩.结果，我们一家五口(父母，两个姐姐和我)为了选台而争执起来。最后，我们决定应当看“最有意思”的节目——如果我们在什么是“最有意思”上可以认同的话。
不过我们全都清楚地记得，买了电视后的好长一段时间里，只有一两个频道可供选择。电视频道的增多反映出我们生活中的一个重大变化:选择余地的扩大。
20xx年前，我们身着同样的款式，单一的色调。而如今，纷繁的花色和众多的式样让我们挑得眼花缭乱。
20xx年前，我们几乎无报可读。而如今，除了大大小小的中文报纸，我们还读上了《中国日报》、《21世纪报》这样的英文报纸。
20xx年前，英语专业的学生只能选语言与文学课程。而如今，我们还学习西方文化，新闻，商务，国际关系，甚至还有计算机课程。
选择的涌现标志着中国进入了一个崭新的时代，一个充满多样化的时代，一个物质与精神都愈加丰富的时代，一个中华民族获得新生的时代。
我们为选择之多而欢呼雀跃，同时也深深地感到这一切来之不易。
一个半世纪之前，在西方大炮、战舰的威通下，中国被迫打开了国门。经过祖祖辈辈的抗争与牺牲，我们才最终赢得了当家作主的机会。改革开放这个正确的抉择使一切发生了翻天覆地的变化。
我和其他同龄人一样，太年轻了、没有经历过中国人丧失选择权的岁月。但是，随着下个世纪的脚步越走越近，我们是该们心自间了:选择，对于我们青年一代，到底意味着什么?
选择，是场靠侥幸来获胜的游戏吗?是句不用兑现的空话吗?抑或是种让人知难而退的困境?
首先，我认为，选择意味着抓住机遇。
我是英语专业三年级学生，我所面临的一个重大选择当然是毕业后的去向。我可以攻读硕士学位，或在国内，或在国外。我可以走上工作岗位，做名教师，翻译，记者，编辑或外交家.实际上，双向选择的体制在我面前铺开了通向各行各业的大道。
说真的，这个选择并不好做。我愿意在像北京、上海、深圳这样的大都市里工作，我也盼着能回到虽不那么发达却使我倍感亲切的故乡。我希望可以留在生活节奏快，令人兴奋的沿海地带，我也愿意扎根于广炭的中西部地区，那里虽然条件艰苦，却有极大的发展潜力。
所有这一切听上去令人振奋，但它们毕竟只是可能性。有些人面对五花八门的选择挑得眼花缭乱，我要告诉他们:选择就意味着接受挑战。
对于我们青年一代，挑战常以竟争的形式出现。到下个世纪，竞争者将不仅只是其他大学毕业生，更有各行各业不同年龄层的人们。
随着国际交流的不断增多，我们得面对来自整个外部世界日益激烈的竞争，这就对我们个/、的发展提出了更高的要求。
20xx年前，懂门外语或会用计算机是个优越条件。但今天，随着受教育面的拓宽，以上的知识也成了每个人必备的条件。
在这种形势下，即便最细小的选择也要求我们具有极大的智慧和自主精神。
当我们面对选择不断增强自己的主动性时，每一次选择的结果也同样变得愈加重要。
比方说，核能可以提高人民的生活水平，可它同样也能毁灭千百万人的生命财产。
经济的发展使我们富裕起来，却也给我们的空气、水、健康带来了严重危害。有些人对选择的后果毫不在乎，我要对他们说:选择还意味着承担责任。我们替自己做选择时，不能随口一句“这不关别人的事”。作为下个世纪的决策者，我们必须承担对和我们共同拥有这个地球的人们所负的责任。 传统的中华文化教育我们，要勃奋学习，努力工作，以荣耀家门。然而我认为，这个家门并不只指诸如我的那个争看电视的五口小家。更确切地说，它指的是整个人类这个大家庭。当我为自己的未来做出选择时，我不会忘记自己第一次正确读出“China"这个单词时老师脸上的笑容。我也不会忘记在我们的帮助下重返校园的江西山区的孩子们兴奋的脸庞。我更不会忘记饱受战火、饥荒、贫困蹂蹦的波斯尼亚、车臣、索马里，不会忘记那里成千上万的妇女儿童泪水模糊的双眼。
所有这些我认识或不认识的人们组成了人类这个大家庭。他们从不同的时空中走进了我的生活，开拓了我的视野。现在，我将为自己做出抉择，该是为使他们的生活变得美好而奋斗的时候了。因为只有当每个人都过上和平、富足的生活，世界才能成为大家的乐园.
ladies and gentlemen,
my name is zhang xinyu. today, im going to talk about growing pains. different people have different pains from different places. we are now students,so i think we have pains mainly from studies. time files.
two months ago, i came to a middle school student.but i have a pain.homework is my growing pain. in the secondary school, we have more subjects to study.and homework is more than primary school.so i could’t adapt to the secondary school’s homework. i don’t have other time to do any sports or read any books. however, i think all pains will fade away in the end. i believe that i can adapt the school life step by step. try my best. that’s all. thank you for your attention.
i have the answer to a question that we've all asked. the question is, why is it that the letter x represents the unknown? now i know we learned that in math class, but now it's everywhere in the culture -- the x prize, the x-files, project x, tedx. where'd that come from?
about six years ago i decided that i would learn arabic, which turns out to be a supremely logical language. to write a word or a phrase or a sentence in arabic is like crafting an equation, because every part is extremely precise and carries a lot of information. that's one of the reasons so much of what we've come to think of as western science and mathematics and engineering was really worked out in the first few centuries of the common era by the persians and the arabs and the turks.
this includes the little system in arabic called al-jebra. and al-jebr roughly translates to “the system for reconciling disparate parts.“ al-jebr finally came into english as algebra. one example among many.
the arabic texts containing this mathematical wisdom finally made their way to europe -- which is to say spain -- in the 11th and 12th centuries. and when they arrived there was tremendous interest in translating this wisdom into a european language.
but there were problems. one problem is there are some sounds in arabic that just don't make it through a european voice box without lots of practice. trust me on that one. also, those very sounds tend not to be represented by the characters that are available in european languages.
here's one of the culprits. this is the letter sheen, and it makes the sound we think of as sh -- “sh.“ it's also the very first letter of the word shalan, which means “something“ just like the the english word “something“ -- some undefined, unknown thing.
now in arabic, we can make this definite by adding the definite article “al.“ so this is al-shalan -- the unknown thing. and this is a word that appears throughout early mathematics, such as this 10th century derivation of proofs.
the problem for the medieval spanish scholars who were tasked with translating this material is that the letter sheen and the word shalan can't be rendered into spanish because spanish doesn't have that sh, that “sh“ sound. so by convention, they created a rule in which they borrowed the ck sound, “ck“ sound, from the classical greek in the form of the letter kai.
later when this material was translated into a common european language, which is to say latin, they simply replaced the greek kai with the latin x. and once that happened, once this material was in latin, it formed the basis for mathematics textbooks for almost 600 years.
but now we have the answer to our question. why is it that x is the unknown? x is the unknown because you can't say “sh“ in spanish. (laughter) and i thought that was worth sharing.

In Calaveras, California, there lived a man whose name was Jim Smiley. Jimenjoyed betting somuch that he would bet on anything. If anyone said goodmorning to him, he would bet themthat it was not a good morning. Whenever therewas a horse race or a chicken fight, Jim wouldbet on it. He didn’t care whichside he bet on, as long as he had a bet.
One day, Jim showed a frog to a stranger who had just arrived in Calaveras,and bet thestranger forty dollars that the frog can jump farther and faster thanany other in CalaverasCounty. The stranger said he didn’t see anything about thefrog different from any other, and ifhe had a frog he would bet Jim. Jim lefthis frog with the stranger and go out to find a frog forthe stranger. Meanwhile,the stranger took out a bag of gunshot, forcing the frog’s mouthopen and pouredthe shot into it.
Soon Jim returned with a frog for the stranger.The two frogs were put onthe floor, and theneach man gave his frog a push. The stranger’s frog hopped offsmartly. But Jim’s frog just satthere, unable to move an inch. Jim had nochoice. He gave forty dollars to the stranger, whotook the money and startedaway. Jim picked up his frog, and found it extremely heavy. Heturned it upsidedown, and the gunshot came out. He knew he had been fooled and, like a madman,started running after the stranger.
As he ran, he passed one of his friends, who asked him where he wasgoing.
"To catch a thief!" shouted Jim. "No matter how fast he may run, I'll catchhim. I'll bet you fivedollars!"
在加利福尼亚的卡拉维拉斯县，有个人名叫吉姆?斯迈里。他好打赌，见什么赌什么。要是有人跟他说“早上好”，他会说，这天早上不怎么样，不信就打个赌。只要有赛马和斗鸡，他都要去赌。在哪一边下注他不在乎，有机会赌就行。
有一天，吉姆见到一个来到卡拉维拉斯县的陌生人，就把自己的一只青蛙给他看，说这是卡拉维拉斯全县跳得最快最远的青蛙，不信就打个赌，赌40块钱。陌生人说他看不出那只蛙有什么非凡之处，如果他手头有一只蛙，就赌一赌。听了这话，吉姆就把自己的青蛙交给陌生人看管，出去为陌生人找一只蛙来。他不在的时候，陌生人掏出一口袋***，掰开青蛙嘴，把***灌了进去。
不久吉姆就给陌生人带了一只青蛙回来。两只青蛙在地上摆好，然后各人将各自的青蛙轻轻一推。陌生人的青蛙一下子就跳起来，跳得好快好远。但吉姆的蛙却呆在那里纹丝不动，像钉在地上似的。吉姆无奈，只得交出40块钱。陌生人拿了钱就走了。吉姆把自己的蛙拿起来，觉得沉甸甸的。他把蛙倒提起来一抖，***掉了出来。他知道自己上了当，就像疯子似的去追陌生人。
正跑着，一个朋友瞧见他，不问他风风火火地去干什么。
“去抓贼!”他吼道，“无论他跑得有多快，我都要追上他。不信打5块钱的赌!”
delicacies are tasty, but eating everyday can still make one lose appetite. happiness is what everyone longs for, but too much happiness can spoil people who may not care about the happiness they already have. it's universal to live in happiness without knowing it. the same is true with love. very few people can love the same person passionately all their lives. all love stories come to an end no matter how beautiful they are, which also demonstrate the changeability of love. what one has been chasing wildly may turn into something one wants to get rid of desperately in the end. besides, love is usually blind, especially those who fall in love at the first sight. at the very beginning, both try to demonstrate their beautiful side and cover up their weakness. fooled by the mysterious color of love, one often mistakes the weaknesses as merits. however, as time passes by, frequent contacts make one bored, and even merits become defects, and then the end of love is coming. what's more, there are the capricious men and women who never take love seriously, leaving the devoted ones suffering alone. the saying that the devoted is always abandoned by the heartless has almost become the truth of love affairs. what we can't neglect is that love may turn into hatred, and lovers may also become enemies. the best proof is the numerous divorces.
even though true love is hard to find nowadays, we still can see some true and infatuated boys and girls who readily give up their families, their parents, their studies, their careers and even their lives for love. they love so passionately, crazily and wildly that they hate anyone who is against their love, and may even harm or kill him if he insists on his objection.
In our daily lives, we have many choices to make, such as what to eat forsupper,what clothes to wear, or what to do on weekends. at certain times in ourlives, we need to make even more critical choices, such as which school toattend, what job to take or who to choose as husband or wife. yes, life is amatter of choice. seemimgly, it means a choice of tangible things. but inessence, it means choosing a way of life. life is to be lived, savored, andenjoyed, not to be wasted or complained about.
Hardly can we forget the time when our society faced the grave threat fromthe life-and-death disease--sars. yet, even during those dreadful times, someafflicted people remained optimistic. instead of wearing neutral white masks,some people turned to colouful ones, and thus display a happy mood. and somecreative people dubbed sars to mean "smile and remain smiling." i was deeplytouched by their optimisim, nearly forgetting that we're still in a battle.people who survive these kinds of circumstances, (at some point)decide in theirminds to carry on in spite of the overwhelming odds.
Laid-off workers, typically regarded as the victims of economicadvancement, are subject to desperation that being unmeployed has brought onthem. but, encouragingly, we have witnessed some of them striving hard torebuild confidence toward life and discover new opportunities for demonstratingtheir values.
Although we cannot choose our appearance, inborn gifts and even avoidunexpected disasters and adversities, we do have the privilege to choose to liveoptimistcally,to love our lives, to have dreams, and to cherish hopes.
Every morning when we get up, we have a choice of how we want to approachlife that day. as for me, i choose to be cheerful.
look! there is a rainbow! on the first day of my university life, when iwalked into the campus, there was a rainbow bridging over the fountain, i hadn’tseen rainbow for a long time. i was so excited, and leaped high with joy. myponytail danced with my happiness. it was a propitious sign indicated that mylife in university would be colorful, and actually it is!
after my entry into university, i found my life so busy. what i should dois not only gaining the scholarship but also being a good monitor and leader ofshanghai university percussion band. i got the 1st and 2nd price of scholarshipin my 2 years of study. i organized charity donations for schoolmates withfinancial difficulty or disease. every week, i give drum lesson to new membersof our percussion band. and there are always a lot of non-business performances,such as entertaining guests, celebrating party, cultural exchange with foreignstudents delegations and their bands. of course, part-time job is indispensablein my vacations. i ask for no payment but aim at getting accustomed to thesociety.
sometimes, my friends advise me not to tire myself out with such a tightschedule. i wake up before the rooster crow, and continue working till very latewhen others are enjoying their sweet dreams. every time i come back from therehearsal of percussion band, i have to finish my homework with the help of myown charged light because of the blackout in out dormitory. maybe such kind oflife is something like an ascetic, but we should work hard and try hard in ouryouth, aren’t we?
when i represented shanghai university to take part in the pond’s newcentury lady competition held in may, when i show off on the stage, when iemerged as “the girl of vitality”, i made use of every bit of time to compensatethe classes i had missed, i made use of every chance to learn from other girlswith vitality, versatility and intelligence, i made use of this opportunity topresent our university students’ state of mind.
there is a little bitterness in my busy life, but at the same time, thereis sweetness. it is colorful. i make fun out of it. i love it. when i snatch alittle leisure i lie on the green grass, reading books, i cripple myself in thewindow-seat in our library---the 2nd largest in shanghai---i absorb knowledgelike a hungry sponge, i wonder along the bank of river, listening to oriels inwillows and get a splendid sunset view of the campus. the sky is drunk with thesunset; i am drunk with the sweetness of my like.
As a student, we have experienced many exam. In this in, not failure and success. Facing the two completely different results, what should we do?
In fact, for success, this only represent the past, we should not be proud, people to front, the well now, hold the result, don't make now in the next test defeat. Faced with it, depression is completely unnecessary and draw lessons, to reflect on, still not night, try to start all over again, I believe in the correct understand the reasons, not only will return after success, still can accumulate experience, and know some ways to face setbacks , make oneself become stronger. In a word, whether success or failure, the most important is mentality, put calm, let it go.
There are many students afraid of exam, that, after this I believe the exam for them, not of fear, but the challenge!
As we all know, "Failure is the mother of success." But few people can really understand what the saying means.
In the world, I am sure that no one dare say he hasn't met any trouble all his life. So we must face failure. In fact, failure is not fearful, but important thing is how to face it correctly. Facing failure, people will never take their fate lying down. They will try their best to work harder and harder until at last they succeed.
Not being courageous to face setbacks, people have no chance to enjoy the pleasure of success. So they have nothing to do but feel sad and empty all day and all night. In fact, they lose the chance of success themselves.
My friend, whenever in trouble, please remember, "Failure is the mother of success."
我们都知道，“失败是成功之母”。但很少有人能真正理解这句话的意思。
在这个世界上，我相信没有人敢说他在生活中还没有遇到任何麻烦，所以我们必须面对失败。事实上，失败并不可怕，重要的是如何正确面对它。敢于面对失败，人们将不再被命运打倒。他们越来越努力工作直到最后成功。
不敢面对挫折，人们也就没有机会享受成功的喜悦。他们会无所事事而感到伤心和整天整夜的空虚。事实上，他们丧失了成功的机会。
我的朋友，无论何时你遇到了困难，请记住：“失败是成功之母。”
It is quite usual that one meets failures, for one's life can never be plain sailing. However, different people hold different attitudes towards failure. Some people think it a heavy blow to fail in achieving something and they can not endure failure.
When they meet failure, they will be seriously dejected and can never pluck up their courage to try again.
However, others think it natural to meet failures in one's career. Therefore, they are psychologically prepared. When they meet failures, they will not be frustrated. Instead, they will continue to meet new challenges. As to me, I'm in favor of the latter view. Failure is really a terrible thing but it is also the mother of success. If one draws lessons from failures, in most cases he will get success in the future. Furthermore, one's life can never be smooth sailing; it must be full of difficulies and setbacks. If one is daunted by difficulies and frustrations, he will always be a failure. However, if one holds a positive attitude toward failure, he will overcome difficulties and frustrations to win victory.

Chinese intellectual revolution and sociopolitical reform movement. In 1915young intellectuals inspired by Chen Duxiu began agitating for the reform andstrengthening of Chinese society through acceptance of Western science,democracy, and schools of thought, one objective being to make China strongenough to resist Western imperialism. On May 4, 1919, reformist zeal found focusin a protest by Beijings students against the Versailles Peace Conferencesdecision to transfer former German concessions in China to Japan. After morethan a month of demonstrations, strikes, and boycotts of Japanese goods, thegovernment gave way and refused to sign the peace treaty with Germany. Themovement spurred the successful reorganization of the Nationalist Party and gavebirth to the Chinese Communist Party. See also Treaty of Versailles.

Failure is so common in our life. No one can avoid it. When we fail in doing something, we often feel so depressed that we have no interest in other things. Sometimes failure can also make us lose heart. Therefore, no one wants to be a failure.
Success is what we all hope for, because it can bring us a sense of pride and a good reputation. The moment we succeed, we always feel so proud, as if having everything in our hands. If one enjoys his continuous success in his career, he will be famous and worshiped by others.
However, failure is the mother of success. One failure doesn’t mean you can never be successful. It depends on what we do to deal with failure. Those who are always afraid of failure and can’t go through it will never win. But as long as we can get some lessons and experience from our failure, we’ll be sure to succeed.
hello, ladies and gentlemen, my name is zhang xinyu. today, im going to talk about growing pains. different people have different pains from different places. we are now students,so i think we have pains mainly from studies. time files. two months ago, i came to a middle school student.but i have a pain.

whether there's afterlife, the answer has never been the same. the atheists deny after life, believing that our life is no more than from the cradle to the grave. they may care about their illustrious names after death; they may feel attached to the affection of their offspring, but they never lay their hopes on their afterlife. they may also say that good will be rewarded with good, and evil with evil, but they don't really believe any retribution in their after life.
however, in the religious world or among the superstitious people, the belief in afterlife is very popular. they do not only believe in afterlife, but thousands of reincarnations as well. in the mysterious world, there are the paradise and the hell, the celestial beings and the gods, the buddha and the bodhisattvas.
maybe they really believed it, or maybe they just wanted to make use of people's veneration, the ancient emperors always declared that they were the real dragons, the sons of god, while the royal ministers claimed to be the reincarnations of various constellations. but can the stars reincarnate?
many people burn incense and kowtow, do good deeds and strive for virtues, not just for the present, but mainly to let god see their sincerity so as to be reborn into a better afterlife, or to achieve the highest enlightenment after several lives of practice. they do believe in afterlife. but i can't help asking: suppose there were no afterlife, would you still do good deeds and strive for virtues? and if god does not see what you are doing, would you still be so upright and selfless? if you work, not for serving the public and liberating the others, but just for a better afterlife of your own, isn't it a little too selfish? comparing with this kind of believers, those who don't believe in afterlife, but still keep doing good deeds, are the most sincere and honest philanthropists, because they do them not for themselves but for other.
you may wonder if i believe in afterlife. my answer is: i know nothing about my previous life, so i dare not make improper comments on afterlife. but i do hope there's afterlife! because our present life is so short that so many things slip away before our proper understanding. i have so many dreams, so many wishes, so many ambitions, as well as so many regrets and concerns. if there were no afterlife, all of them will remain unrealized!
i'm not contented with the present commonplace life, i'm very much attached to the affections that should have been mine but have been washed away by the hurrying time, and i yearn for the perfection and maturity if i could start all over again. so believe it or not, i'd rather there were afterlife.
