i am happy to join with you today in what will go down in history as the greatest demonstration for freedom in the history of our nation.

five score years ago, a great american, in whose symbolic shadow we stand today, signed the emancipation proclamation. this momentous decree came as a great beacon light of hope to millions of negro slaves who had been seared in the flames of withering injustice. it came as a joyous daybreak to end the long night of their captivity.

but one hundred years later, the negro still is not free. one hundred years later, the life of the negro is still sadly crippled by the manacles of segregation and the chains of discrimination. one hundred years later, the negro lives on a lonely island of poverty in the midst of a vast ocean of material prosperity. one hundred years later, the negro is still languished in the corners of american society and finds himself an exile in his own land. and so we've come here today to dramatize a shameful condition.

in a sense we've come to our nation's capital to cash a check. when the architects of our republic wrote the magnificent words of the constitution and the declaration of independence, they were signing a promissory note to which every american was to fall heir. this note was a promise that all men, yes, black men as well as white men, would be guaranteed the "unalienable rights" of "life, liberty and the pursuit of happiness." it is obvious today that america has defaulted on this promissory note, insofar as her citizens of color are concerned. instead of honoring this sacred obligation, america has given the negro people a bad check, a check which has come back marked "insufficient funds."

but we refuse to believe that the bank of justice is bankrupt. we refuse to believe that there are insufficient funds in the great vaults of opportunity of this nation. and so, we've come to cash this check, a check that will give us upon demand the riches of freedom and the security of justice.

we have also come to this hallowed spot to remind america of the fierce urgency of now. this is no time to engage in the luxury of cooling off or to take the tranquilizing drug of gradualism. now is the time to make real the promises of democracy. now is the time to rise from the dark and desolate valley of segregation to the sunlit path of racial justice. now is the time to lift our nation from the quicksands of racial injustice to the solid rock of brotherhood. now is the time to make justice a reality for all of god's children.

it would be fatal for the nation to overlook the urgency of the moment. this sweltering summer of the negro's legitimate discontent will not pauntil there is an invigorating autumn of freedom and equality. nineteen sixty-three is not an end, but a beginning. and those who hope that the negro needed to blow off steam and will now be content will have a rude awakening if the nation returns to busineas usual. and there will be neither rest nor tranquility in america until the negro is granted his citizenship rights. the whirlwinds of revolt will continue to shake the foundations of our nation until the bright day of justice emerges.

but there is something that i must say to my people, who stand on the warm threshold which leads into the palace of justice: in the proceof gaining our rightful place, we must not be guilty of wrongful deeds. let us not seek to satisfy our thirst for freedom by drinking from the cup of bitterneand hatred. we must forever conduct our struggle on the high plane of dignity and discipline. we must not allow our creative protest to degenerate into physical violence. again and again, we must rise to the majestic heights of meeting physical force with soul force.

the marvelous new militancy which has engulfed the negro community must not lead us to a distrust of all white people, for many of our white brothers, as evidenced by their presence here today, have come to realize that their destiny is tied up with our destiny. and they have come to realize that their freedom is inextricably bound to our freedom.

we cannot walk alone.

and as we walk, we must make the pledge that we shall always march ahead.

we cannot turn back.

there are those who are asking the devotees of civil rights, "when will you be satisfied?" we can never be satisfied as long as the negro is the victim of the unspeakable horrors of police brutality. we can never be satisfied as long as our bodies, heavy with the fatigue of travel, cannot gain lodging in the motels of the highways and the hotels of the cities. we cannot be satisfied as long as a negro in mississippi cannot vote and a negro in new york believes he has nothing for which to vote. no, no, we are not satisfied, and we will not be satisfied until "justice rolls down like waters, and righteousnelike a mighty stream.

a window is opened up at the crack of dawn, beside which one man is overlooking the the mess of buildings outside, breathing the fresh air cosily. but just after a little while, he steps to his seat, staring at the computer screen till the night. this man is very likely a programmer.

there is a man who concentrates on his computer, but doesn’t care about however he dresses, or even whether he washes his face.

there is a man who has a good knowledge of computer language, but has a low eq and makes a bad relationship with others.

there is a man who stays at home and does his own work by himself day and night, but just has few friends.

these images shown above probably are what people think of programmers as, in fact, programmers indeed give us a bad impression sometimes. however, people just have a partial understanding of programmers’ life, not to mention that they can know the fun of programming. there is no doubt that programs affect all aspects of our lives in an obvious or potential way, especially they are reflected in electronic products that we use nowadays.

when you are so proud of possessing an iphone, you’d better remember that it is the program that makes you get confidence to show off the advanced mobile phones thoroughly.

when you take advantage of computers to cope with problems in life, you’d better remember that it is the program that makes you seek the convenience of computer.

when you needn’t worry about hot summer and cold winter owing to an air-conditioner, you’d better remember that it is the program that makes you share the machine’s intelligent.

when you release your pressure by playing varies of online games, you’d better remember that it is the program that makes you enjoy the great entertainment in life.

as people’s thoughts control their bodies, computer programs play a leading role in the modern times. both social progress and human evolution depend on the computer programs. in the practical application, a software consists of different programs and then combines with hardware to develop into a high-tech electronic product. there are many kinds of electronic products found everywhere in our daily life. nearly all the time do we make use of these products to conduct our passion.

my definition of success

today i am very glad to be here to share with you my ideas of success. what is success? it is what everyone is longing mes success would be rather simple. winning a game is success; getting a high grade in the exam is success; making a new friend is success; even now i am

standing here giving my speech is somehow also success.

however, as a person’s whole life is concerned, success becomes very

complicated. is fortune success? is fame success? is high social status success? no, i don’t think so. i believe success is the realization of people’

s hopes and ys, in the modern society there are many people

who are regarded as the successful. and the most obvious characteristics of hem are money, high position and luxurious life. so most people believe that s success and all that they do is for this purpose. but the problem is wether it is real success. we all know there are always more money, higher position and better condition in front of us. if we keep chasing them, where is the end? what will satisfy us at last? therefore, we can see, to get the real success we must need something inside, which is the realization of

people’ hopes and ideals.

different people have different ideas about success; cause people’s hopes and ideas vary from one another. but i am sure every success is dear to everybody, cause it is not easy to come by, cause in the process of our striving for success, we got both our body and soul tempted, meanwhile we are enlightened by the most valuable qualities of human beings: love, patient, courage and sense of responsibility. these are the best treasures. so now i am very proud that i have this opportunity to stand here speaking to all of you. it is my success, cause i raise up to challenge my hope.

what is success? everyone has his own interpretation as i do. but i am sure

every success leads to an ever-brighter future. so ladies and gentlemen, believe in our hopes, believe in ourselves, we, every one of us, can make a

successful life! wish you all good success!

敬的各位領導、老師，親愛的同學們：

大家下午好!矯健的蒼鷹扇動著雙翅，無畏的目光點亮前行的道路。呼吸一口新鮮的空氣，讓久儲的夢想復活，讓我們一起飛翔!信管04503班的楊國興給您們帶來最真摯的演講。今天我演講的題目是《而今邁步從頭越》。

大學的我們渴望收獲才華，學富五車。我們渴望搏擊信息大潮，收獲才能，引領it走向。胡適先生說過：“學問是鑄器的工具，放棄了學問，便摧毀了自己。”然而，我們校園中出現有背于學校主流文化的現象，卻不由得讓我們重新進行了思考。我們的學生是否還懷有拼搏、收獲的心，對待生活。

在課堂上沉浸在電腦世界、手機世界里的同學們，我們是否想過我們每天收獲了什么?

在校園的幽僻處，總有幾個‘人約黃昏后’，動情處他們竟會旁若無人。我們那樣就不覺得慚愧嗎?

此外，在宿舍里的‘騰云駕霧’，‘快活似神仙’，考場中的照抄作弊，熄燈后的大呼小叫。作為中跨世紀新一代青年就是我們這樣嗎?

我們可知道這樣做對自己、對同學、對學校有多大的影響。斷送了自己的學業，剝奪了同學學習的機會，影響了學校的學風建設。現在的社會是一個競爭的社會，沒有過硬的本領，沒有豐富的知識，是無法在社會上立足的。

生活腐化，追求時尚，崇尚名牌。玩物喪志，沉溺于網絡世界。理性侏儒，缺乏判斷能力和審美能力。學術精神的失落，道德低下，行為放蕩，缺乏信仰，缺乏毅力，缺乏進去精神和承受力。如果您是老板，您會選擇我們這樣的員工嗎?

同學們，看看吧!看看李開復教我們怎樣度過大學四年。他說到：大學四年是人生中最關鍵的階段。從入學的`第一天起，你就應當對大學四年有個正確的認識和規劃。

同學們，醒醒吧!是該醒的時候了。不要被習慣所掩蓋，被時間所迷惑，被惰性所消磨。讓我們問問自己，我們對得起含辛茹苦的父母嗎?如果父母知道我們在學校中的表現，父母是多么的傷心。同學們讓我們拿起筆算一算四年我們需要花費多少錢，我們是否對的得起父母為我們付出的一切。

同學們，想想吧!是該想的時候了。羅馬并非一日建成，成功更非一蹴而就。為了自己，為了在畢業以后找到好的工作。我們是時候該充實自己，完善自己了。

同學們，一起努力吧!只有全心奮斗，才有滿心收獲。

科技演講比賽的演講稿篇五

hello,everyone. good afternoon. thank you for giving me this opportunity to talk about my top concern. i'm no.26, i'll talk about friend.

everyone of us,rich or poor,should at least have one or two good friends. my friend will listen to me when i want to speak, will help me when i need,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.

when i was ten, i was suddenly confronted with the anguish of transferring to other school. i had to left my friends i had ever known. as a kid,i feel lonely when i study in a new environment without a person i had known. nobody i could talk,nobody could know when i feel lonely. the time when i couldn't sleep, i'll always miss them, then the tears filled my eyes.

later, i became familar with the environment ,and made some friends ,which became my best friends then. they talked with me when i felt lonely, they helped me when i needed, they took care of me when i was sick. even through we were part, we still keep in touch with each other.

in our whole lives,we'll meet too much people but only a few can be our best friends. when staying with them,we can release ourself completely. we can do whatever we want, we can laugh together, talk together, and even cry together. i should say that being together with our best friends is the most wonderful moment of our lives.

but in this fast-developing modern society, the reality is not that. more and more people forget to enjoy 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. they have few time to share with their friends. with the time goes by, they will be far away from each other.

friend is kind of treasure in our lives. it's actually like a bottle of wine, the longer it is kept, the sweeter it will be. it also likes a cup of hot tea, when we are in bed time, it will warm our broken hearts.

friends,especially best friends. it is what we should have in our lives,and it can make our lives be colorful go beyond our imagination.

thanks for your listening. this is what i concerned.
