From Walls to Bridges

I'm studying in a city famous for its walls. All visitors to my city are amazed by the imposing sight of the city walls, silhouetted by the setting sun with gold and shining lines. With old, cracked bricks patched with lichen, the walls are weather-beaten guards, standing still for centuries in protecting the city.

Our ancestors liked to build walls. They built walls in Beijing, Xi'an, Nanjing and many other cities, and they built the Great Wall, which snakes through half of our country. They built walls to ward off enemies and evil spirits. This tradition has been maintained to this day as we still have many parks and schools walled off from the public. I grew up at the foot of the city walls, and I've loved them since my childhood. For a long time, walls were one of the most natural things in the world.

My perception, however, changed after a hiking trip to the Eastern Suburbs, a scenic area of my city. My classmates and I were walking with some international students. As we walked out of the city, we found ourselves flanked by taller and taller trees, which formed a huge canopy above our heads. Suddenly an international student asked me, "Where is the entrance to the Eastern Suburbs?"

"We're already in the Eastern Suburbs," I replied.

He seemed taken aback, "I thought you Chinese have walls for everything." His remark set off a heated debate. At one point, he likened our walled cities to "jails," while I insisted that the Eastern Suburbs were one of the many places in China that had no walls.

That debate had no winners, but I did learn a lot from this international student. For instance, he told me that universities like Oxford and Cambridge were not surrounded by walls; the campuses were just part of the cities. I have to admit that we do have many walls in China, and as we are developing our country, we must carefully examine them, whether they are physical or intangible. We will keep some walls but tear down those that impede China's development.

Let me give you an example.

A year ago, when I was working on a term paper, I needed a book on business law and found a copy in the law school library. However, the librarian turned down my request with a cold shoulder, saying, "You can't borrow this book, you are not a student here." In the end, I had to spend 200 yuan buying a copy; meanwhile, the copy in law school was gathering dust on the shelf.

At the beginning of this semester, I heard that my university has started not only to unify its libraries but also link them up with libraries of other universities, so my experience will not be repeated. Barriers will be replaced by bridges. Through an inter-library loan system, we will have access to books from any library. With globalization, with China integrated into the world, I believe many of these intangible walls will be knocked down.

I know globalization is a controversial issue, and it is hard to say whether it is good or bad. But one thing is for sure: it draws our attention to China's tangible and intangible walls and forces us to examine their roles in the modern world.

And how about the ancient walls in my city and other cities? Should we tear them down? Just the opposite. My city, like Beijing and other cities, is actually making a great effort to preserve the walls. These walls attract not only historians and archeologists but also many schoolchildren trying to study our history and cultural heritage. Walls have turned into bridges to our past and to the rest of the world. If the ancient builders of these walls were still alive today, they would be proud to see such great change in the role of their walls. They are now bridges that link East and West, South and North, and all countries of the world. Our cultural heritage will survive globalization.

ladies and gentlemen , good afternoon! i’m very glad to stand here and give you a short speech. today my topic is “youth”. i hope you will like it , and found the importance in your youth so that more cherish it.

first i want to ask you some questions:

1、do you know what is youth?

2、how do you master your youth?

youth

youth is not a time of life, it is a state of mind ; it is not rosy cheeks , red lips and supple knees, it is a matter of the emotions : it is the freshness ; it is the freshness of the deep springs of life .

youth means a temperamental predominance of courage over timidity of the appetite , for adventure over the love of ease. this often exists in a man of 60 more than a boy of 20 . nobody grows old merely by a number of years . we grow old by deserting our ideals.

years 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 60 of 16 , there is in every human being ‘s heart the lure of wonders, the unfailing childlike appetite of what’s next and the joy of the game of living . in the center of your heart and my heart there’s a wireless station : so long as it receives messages of beauty , hope ,cheer, courage and power from men and from the infinite, so long as you are young .

when the aerials are down , and your spirit is covered with snows of cynicism and the ice of pessimism, then you are grown old ,even at 20 , but as long as your aerials are up ,to catch waves of optimism , there is hope you may die young at 80.

thank you!

What College Education Means to Me

the title of my speech is “what college education means to me”.now reflecting on the past two and half years of my college experience, i come to realize how much it has shaped me.

for me, college education is a marvelous ship-builder who designed me from kneel plates up.

with great vision, college education has equipped me, first with a powerful propeller----the sophisticated knowledge in certain field and wide exposure to other disciplines. by dedicating myself to the engineering courses in the day and immersing myself in the rich banquet of the world literature at night, i’ve amassed the driving force for the future and enriched my soul.

besides, college education has also provided me with a precise compass----the sense of social responsibility. how can i best serve the interest of the public while achieving my self-fulfillment? my one year’s experience as a part-time english teacher has testified: to be valuable to society as well as to find my place, i have to possess some actual strength and the ability to function well in the most challenging situation. amid the hectic schedule that balances club activities, sports, and academic courses, i feel the rhythm and beauty in the intensity of my high-pitched life, knowing that i ’m on the right way.

and more importantly, college education has set up not only single ships, but also fleets with common destinations. by interacting with friends of common beliefs, i’ve acquired skills of relating to other people.

now ,as a ship about to make my maiden voyage ,i’m still not in the position to tell what’s waiting ahead of me ,but with a powerful propeller, a precise compass and ardent companions of sailing in the sea of society, i’m ready to be a great sea-explorer.

thank you.

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.

Money and Honor

the duality of money has been puzzling people since its first appearante. on the one hand, clean money can sweeten your life, help you succeed and be your lifelong faithful companion. on the other hand, dirty money may posion your mind, ruin your happiness and discard you suddenly as a false friend.

the market economy tells us that everyone should earn a living by selling something. professors sell their knowledge, workers sell their labor, farmers sell their produce. money now appears more powerful than anything else and drives people crazy. the temptation of money often challenges one's honor. we are not ashamed to make more money to have a better life by our sweat. however,there is a widespread concern that millionaires become the heroes no matter whether they make any contribution to our society. some people try desperately to make big money, which, more often than not, end up with degradation, corruption and crime.

though money is indispensable to our life, dirty money may drag us into hell. there are many things no money can buy. we will keep our honor intact at any cost because it is our soul. love of money is the root of all evil. for myself, i would rather die than dishonor myself for money.

love has magical power that can exploit people's potential abilities, bring people's positive factors into full play, and provide people with the courage to face trials and hardships, to go through life and death, and even to risk universal condemnation. even in the ancient feudal society, some people were courageous enough to carry on clandestine love affairs. the examples in point were the courageous ones who dared to love the concubines of the emperors or the children of their foes. love also has miraculous power which can startle the universe and move the gods by attracting the heavenly celestials coming down to earth ( the love story of the cowboy and the weaving girl ),and by turning ghosts into human ( strange tales of liao-zhai ),love can transcend age and generation (dr. sun yat-sen and madam song qingling; luxun and xu guangping).love can show contempt for all conventions and prejudices; love can heal wounds and cure diseases, and love can readjust people's state of mind. of course, the result would be the opposite once it hurts.

great men yearn for true love even more than ordinary people. since the ancient times, so many heroes couldn't help falling into the trap of love that the sex-trap has been regarded as one of the 36 stratagems in military tactics. fuchai, the king of the wu state, couldn't be spared of this trap, and generals dongzhuo and lubu fell deeply into it while xiangyu, the king of the western chu state , bid farewell to his beloved concubine in tears. people may have to pay very high price, even their illustrious name for the love they long for even though it may last for only a very short time. nonetheless no one can tear himself away from love. people often say that their earthly affinity is not yet finished, but in fact it is the love affinity that is the most difficult to finish.

Good afternoon ，ladies and gentlemen!

I’m very honored to stand here and give you a short speech! To begin with ,I want to ask a question .Does everybody dream a good dream last night? Actually ,today I want to talk about dream with you. Of course, What I want to talk is not a dream you have last night,but a dream—— about life.

Everyone has dreams about life, different dreams at different life stage,and we need dreams to support us. Dreams are like the stars we never reach in the sky,but like most mariners(水手),we can chart our course by them. With the dream,we have a direction,with a direction, we were no longer confused.With the dream, there is hope,With hope, we have the strength to fight.

I have a dream: To be a doctor.，because doctor may relieve the pain of patients. May let the human change the health. At the same time, I believed that, those who help others may be able to obtain joyfully. Therefore, I hoped in the near future ,I might be a doctor.

But I know，life is tough,and there are always ups and downs, maybe we fail in the way to our aims,and we may feel depressed ,whenever at this time, the dream in our heart can always comfort us, encourage us ,and support us to move ahead .

Young!Fortunately, I am young now. Just due to it, I know that nothing is impossible.I firmly believe that nothing can stand in my way. If I can't realize my dream,it result from that I haven't work harder enough and I won't find other excuses. If no people believe you, you can make it to prove that you are right. If you think the god haven't blessed you and there is no truth here, you can become the god and create the truth.

"My breath swallows the sky and make the yellow river overflow, my sword is famous in Kyushu and it can collapse the five sacred mountains." At some time in the past I also had am bitious words and I had some achievements. Each achievement results from my hard work. I always believe that "If you want to have more achievements than others, you must work harder." In some extent, the dream is the hope. If you can insist on doing something, the victory will come.

Hold fast to dreams, for if dreams die, life is a broken-winged bird that cannot fly. Hold fast to dreams, for when dreams go, life is a barren field frozen with snow. So my dear friends, think of your old and maybe dead dreams. Whatever it is, pick it up and make it alive from today. Let's--- move ----out!

Thank you for your listening!

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.

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.

We often hear people say, “Never give up.” These can be encouraging words and words of determination. A personwho believes in them will keep trying to reach his goal no matter how manytimes he fails. In my opinion, the quality of determination to succeed is animportant one to have. Therefore, I believe that we should never give up.

One reason is that if we give up too easily, we will rarely achieveanything. It is not unusual for us to fail in our first attempt at somethingnew, so we should not feel discouraged and should try again. Besides, if wealways give up when we fail, we will not be able to develop new skills and growas people. Another reason we should never give up is that we can learn from ourmistakes only if we make a new effort. If we do not try again, the lesson wehave learned is wasted. Finally, we should never give up because as we work toreach our goals, we develop confidence, and this confidence can help us succeedin other areas of our lives. If we never challenge ourselves, we will begin todoubt our abilities.

In short, it is important that wedo not give up when working for our goals. Whether we succeed in the end ornot, we will learn something, and what we learn will help us to become better,more confident people. Furthermore, if we give up, we have non chance ofattaining our goals, but if we keep trying, there is always a chance that wewill succeed one day.

Thank you !

good morning! ladies and gentlemen，today i will make a speech here 。 my topic is the importance of environment。

so many people talk about protect environment but very few actually do。this is because they dont really understand the importance of the environment。next im going to tell a story。 it will tell you how important the environment is。

long long ago，there was a kind of animal called dinosaur。 they were the biggest animals on earth。they were also very strong。 but because of the environment，they were disappeared。

were humans stronger than the dinosaurs? the answer must be no。 a dinosaur can easily kill a dozen people。but as strong as they still could not withstand the threat environment。 do you think we can?the answer is certainly not。 so we knew the importance of the environment。

the earth gives us a good environment。 we must learn to cherish， cherish this opportunity。

so ，we must protect the environment。 as a student，we can also do a lot of helpful things。 for example，we can protect it by not throwing rubbish away，we can save water to make full use of it and so on。

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.

(applause)

now i think at this point it's important for me to say that i actually love extroverts. i always like to say some of my best friends are extroverts, including my beloved husband. and we all fall at different points, of course, along the introvert/extrovert spectrum. even carl jung, the psychologist who first popularized these terms, said that there's no such thing as a pure introvert or a pure extrovert. he said that such a man would be in a lunatic asylum, if he existed at all. and some people fall smack in the middle of the introvert/extrovert spectrum, and we call these people ambiverts. and i often think that they have the best of all worlds. but many of us do recognize ourselves as one type or the other.

and what i'm saying is that culturally we need a much better balance. we need more of a yin and yang between these two types. this is especially important when it comes to creativity and to productivity, because when psychologists look at the lives of the most creative people, what they find are people who are very good at exchanging ideas and advancing ideas, but who also have a serious streak of introversion in them.

and this is because solitude is a crucial ingredient often to creativity. so darwin, he took long walks alone in the woods and emphatically turned down dinner party invitations. theodor geisel, better known as dr. seuss, he dreamed up many of his amazing creations in a lonely bell tower office that he had in the back of his house in la jolla, california. and he was actually afraid to meet the young children who read his books for fear that they were expecting him this kind of jolly santa claus-like figure and would be disappointed with his more reserved persona. steve wozniak invented the first apple computer sitting alone in his cubical in hewlett-packard where he was working at the time. and he says that he never would have become such an expert in the first place had he not been too introverted to leave the house when he was growing up.

now of course, this does not mean that we should all stop collaborating -- and case in point, is steve wozniak famously coming together with steve jobs to start apple computer -- but it does mean that solitude matters and that for some people it is the air that they breathe. and in fact, we have known for centuries about the transcendent power of solitude. it's only recently that we've strangely begun to forget it. if you look at most of the world's major religions, you will find seekers -- moses, jesus, buddha, muhammad -- seekers who are going off by themselves alone to the wilderness where they then have profound epiphanies and revelations that they then bring back to the rest of the community. so no wilderness, no revelations.

love is shapeless and priceless. we can blame nobody when captured by it. love can not be forced, nor can it be pretended. sympathy is not love, neither is gratitude. love must be generated from the heart, and expressed in actions. it can not be called love without passions and a deep longing from the bottom of the heart. there's no impassable gulf between family love and fraternal love. some family love may turn into friendship. at the same time, natural barriers doesn't exist either between fraternal love and amatory love. some friendship may develop into amatory love. the same is true with amatory love which may change into family love after a long time of mutual grinding and polishing.the closer the relationship, and the higher the expectations are, the more difficult it is to get along with each other. family love, fraternal love and amatory love are three main human feelings. if handled well, they can bring us extreme happiness, while handled improperly, will bring us great sufferings.

the present society is a world of dazzling money and dwindling human feeling contacts. most people hold a snobbish attitude. they only make friends with people of wealth and of high social status. just as zhen shiyen said in his expounding of the song “all good things must end” in a dream of the red mansions “while men with gold and silver by the chest, turn beggars scorned by all and dispossessed”.frankly speaking, however, if we regard money the first thing in whichever one of the three kinds of loves, it will depreciate and even become worthless.

Here are the beacon tower, also known as beacons, Wolf yantai. Independent buildings is not connected to the Great Wall.

After three things done, she threw herself into the sea.
