第一篇：人為什么要睡覺英語演講稿三分鐘

my chinese dream 我的中國夢 i am very glad to stand here to give thier a short speech.today my topic is that the youth are the future of motherland 很高興站在這里做這篇短小的演講，我演講的主題是青年是祖國的未來。

在準(zhǔn)備英語演講比賽的時候，我本想簡單地從網(wǎng)上搜索一些文章作為我演講的內(nèi)容。我看過很多文章，有著名主持人的、北大教授的、大學(xué)生的，也有初中生的。但是看完之后，我放棄了當(dāng)初的想法，我甚至為當(dāng)初的想法感到有一些羞愧。因為今天我站在這里向大家演講的主題，是一個莊重而嚴(yán)肅的主題；是一個充滿榮耀與自豪的主題；是每一個中華兒女共同期盼的主題。每個人都有屬于他們自己的中國夢，而我，當(dāng)然也有一直縈繞在心懷只屬于我的中國夢。

so what?s my chinese dream ? finally i will announce.we had learned a lot of knowledge and understood a lot of truth in the book.we had a basic concept to our country at that time.we know that our country is full of sunshine , and we are the future of our country, and our dreams are to be the hope of our motherland.我的中國夢是什么樣的？先賣個關(guān)子。

記得剛剛上學(xué)那會兒，我們天真無邪。在課本里，我們學(xué)到了很多很多知識，也明白了很多很多道理，我們對祖國也有了一個最基本的概念。我們知道我們的祖國到處充滿陽光，正在慢慢發(fā)展，而我們，就是祖國未來的花朵，未來的希望。我們夢想將來能夠成為祖國的希望。

這，是我們最初的中國夢。最真誠的我們，最真誠的夢。

但是，不知道什么時候開始，我們長大了，生活似乎一下子變得和以前不太一樣了，與此同時，雖然我們很不想承認(rèn)但是卻又不得不承認(rèn)的是，我們的思想，我們的為人處世觀，我們對我們祖國的看法，也潛移默化中慢慢開始了轉(zhuǎn)變。我們的社會變得到處充滿欺騙、冷漠、勾心斗角、壓力、腐敗、險惡，我們變得暴躁，不冷靜，憤世嫉俗。我們的國家，似乎也開始變得千瘡百孔。而好多我們親愛的祖國委以重任培養(yǎng)的青年學(xué)生們變得輕浮、急躁，更別提什么夢想，什么中國夢了？ are we sick, or is our dear motherland sick? 我很驚訝，當(dāng)大街上有老人摔倒，我們不敢再去扶起；我很難過，當(dāng)有人做了好事被報道，更多的人說他做作；我很傷心，當(dāng)我看到我們眾多的青年人變得冷漠、市儈、欺詐以及缺乏理想。

到底是我們病了，還是我們親愛的祖國病了？ i dont want to talk about the construction of our country politics, and also speak impassioned speech on the diaoyu island event.i just want to appeal young people,showing the side of youth,good and confidence.we must learn to organize our own thoughts, correct our own concept, and change our direction to the right side in future life.china dream actually lies in our young generation, especially of the intellectuals.我的中國夢，不想大談?wù)危膊幌雽︶烎~島事件發(fā)表慷慨激昂的演講。我只想呼吁，呼吁我們年輕人，呼吁我們祖國的希望能夠?qū)⑽覀兊那啻阂幻?，將我們的善良一面，將我們的自信一面好好展現(xiàn)出來。我們要學(xué)會整理自己的思想，端正自己看問題的觀念，擺正自己的人生方向。我們的中國夢實際上正掌握在我們自己手上，掌握在我們年青一代，尤其是知識分子手上。也許，一個人，是渺小的；但是當(dāng)他和祖國聯(lián)系起來時，就是偉大的。也許，一個夢想，是渺小的，但是當(dāng)它成為祖國的夢想時，就是不可估量的。也許，我無法用自己一個人的力量撬起整個中國，但是我們千千萬萬年輕人一起為祖國的夢想去奮斗時，我們的祖國就足以令世界顫抖、動容。i dream to construct our beauty china with millions of young people who have the same dream.we do it without exaggeration but only with persistence.我夢想和萬千具有相同夢想的年輕人去建設(shè)我們的美麗中國，沒有虛浮，只有執(zhí)著，只有奮斗，只有勇于擔(dān)當(dāng)。這就是我的中國夢！that is my speech,thanks everyone.我的演講就到這里，謝謝大家。we are the world ,we are the future 世界是我們的，未來是我們的 someone said “we are reading the first verse of the first chapter of a book, whose pages are infinite”.i don?t know who wrote these words, but i?ve always liked them as a reminder that the future can be anything we want it to be.we are all in the position of the farmers.if we plant a good seed ,we reap a good harvest.if we plant nothing at all, we harvest nothing at all.一些人說?我們正在讀一本無窮的書中的第一章的第一節(jié)。?我不知道誰寫了這些話，但是我一直很喜歡它，因為它提醒了我，我們能夠創(chuàng)造我們想要的未來。we are young.“how to spend the youth?” it is a meaningful question.to answer it, first i have to ask “what do you understand by the word youth?” youth is not a time of life, it?s a state of mind.it?s not a matter of rosy cheeks, red lips or supple knees.it?s the matter of the will.it?s the freshness of the deep spring of life.我們都是農(nóng)夫。如果我們播下好的種子，我們將會豐收。如果我們的種子很差，有很多草籽，收割的將是無用的莊稼。如果我們什么也不播種，什么收獲也沒有。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.我們是年輕的。?怎樣度過青春??這是個有意義的問題。為了去回答它，我首先要問?從‘青春’這個詞中你能理解到什么?? 青春不是人生的一個時期，而是精神的一種狀態(tài)。青春不是桃面、丹唇、柔膝，而是深沉的意志。青春是生命的深泉在涌流.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.a poet said “to see a world in a grain of sand, and a heaven in a wild flower, hold infinity in the palm of your hand, and eternity in an hour.several days ago, i had a chance to listen to a lecture.i learnt a lot there.i?d like to share it with all of you.let?s show our right palms.we can see three lines that show how our love.career and life is.i have a short line of life.what about yours? i wondered whether we could see our future in this way.well, let?s make a fist.where is our future? where is our love, career, and life? tell me.yeah, it is in our hands.it is held in ourselves.一位詩人說?從一粒沙看世界，從一朵花看天堂，把無限放在你的手掌，永恒在一剎那里收藏?。幾天前，我有了一個聽講座的機會，從中我學(xué)到了很多東西?，F(xiàn)在，我想把這些與大家共享。讓我們伸出右手，我們可以看到手掌中的展示我們的愛，事業(yè)和生活的三條線。我在生活方面這條線很短，那你們的呢?我想知道我們是否可以用這種辦法去看我們的未來。好的，讓我們一起握拳。我們的未來在哪兒?我們的愛、事業(yè)和生活在哪兒?告訴我!是的，它們就在我們的手中。它們被我們自己掌握著。we all want the future to be better than the past.but the future can go better itself.don?t cry because it is over, smile because it happened.from the past, we?ve learnt that the life is tough, but we are tougher.we?ve learnt that we can?t choose how we feel, but we can choose what篇二：三分鐘英文演講稿

題目

《人為什么要長大呢》

有位名人講過：當(dāng)一個人開始回憶過去，他就已經(jīng)老了?？墒俏蚁胝f：不對。當(dāng)我剛剛來到保定，面對這個陌生的城市，面對這個陌生的校園，面對一張張陌生的面孔，我不禁回憶起以前點點滴滴的美好時光。想起小時候的天真，可愛；想起上學(xué)時代那些一起玩耍的伙伴。

小時候的我們，總把父母當(dāng)成是自己心目中的神，總認(rèn)為父母是無所不能的?？墒俏以吹竭@樣一則故事：有位母親有一天想念自己的孩子，于是就冒著大雪帶著自己親自給孩子烤的番薯到學(xué)校去看望自己的孩子，可是剛到學(xué)校門口就被自己的孩子拉住。說是自己的母親穿著太寒磣，怕在自己的同學(xué)面前丟臉。類似這樣，孩子長大之后怕自己的父母給自己丟人，而不讓父母在同學(xué)同事面前露臉的事，在當(dāng)今社會真的是屢見不鮮。這些事情真的讓我很費解，為什么當(dāng)初自己心目中的神，那個自己曾經(jīng)認(rèn)為無所不能的人，隨著自己一天天的長大，會把當(dāng)成是給自己丟人

簡介：一生中，我們有三分之一的時間都在睡眠中度過。關(guān)于睡眠，你又了解多少?睡眠專家russell foster為我們解答為什么要睡覺，以及睡眠對健康的影響。

what i'd like to do today is talk about one of my favorite subjects, and that is the neuroscience of sleep.now, there is a sound--(alarm clock)--aah, it worked--a sound that is desperately, desperately familiar to most of us, and of course it's the sound of the alarm clock.and what that truly ghastly, awful sound does is stop the single most important behavioral experience that we have, and that's sleep.if you're an average sort of person, 36 percent of your life will be spent asleep, which means that if you live to 90, then 32 years will have been spent entirely asleep.now what that 32 years is telling us is that sleep at some level is important.and yet, for most of us, we don't give sleep a second thought.we throw it away.we really just don't think about sleep.and so what i'd like to do today is change your views, change your ideas and your thoughts about sleep.and the journey that i want to take you on, we need to start by going back in time.“enjoy the honey-heavy dew of slumber.” any ideas who said that? shakespeare's julius caesar.yes, let me give you a few more quotes.“o sleep, o gentle sleep, nature's soft nurse, how have i frighted thee?” shakespeare again, from--i won't say it--the scottish play.[correction: henry iv, part 2](laughter)from the same time: “sleep is the golden chain that ties health and our bodies together.” extremely prophetic, by thomas dekker, another elizabethan dramatist.but if we jump forward 400 years, the tone about sleep changes somewhat.this is from thomas edison, from the beginning of the 20th century.“sleep is a criminal waste of time and a heritage from our cave days.” bang.(laughter)and if we also jump into the 1980s, some of you may remember that margaret thatcher was reported to have said, “sleep is for wimps.” and of course the infamous--what was his name?--the infamous gordon gekko from “wall street” said, “money never sleeps.”

what do we do in the 20th century about sleep? well, of course, we use thomas edison's light bulb to invade the night, and we occupied the dark, and in the process of this occupation, we've treated sleep as an illness, almost.we've treated it as an enemy.at most now, i suppose, we tolerate the need for sleep, and at worst perhaps many of us think of sleep as an illness that needs some sort of a cure.and our ignorance about sleep is really quite profound.why is it? why do we abandon sleep in our thoughts? well, it's because you don't do anything much while you're asleep, it seems.you don't eat.you don't drink.and you don't have sex.well, most of us anyway.and so therefore it's--sorry.it's a complete waste of time, right? wrong.actually, sleep is an incredibly important part of our biology, and neuroscientists are beginning to explain why it's so very important.so let's move to the brain.now, here we have a brain.this is donated by a social scientist, and they said they didn't know what it was, or indeed how to use it, so--(laughter)sorry.so i borrowed it.i don't think they noticed.okay.(laughter)

the point i'm trying to make is that when you're asleep, this thing doesn't shut down.in fact, some areas of the brain are actually more active during the sleep state than during the wake state.the other thing that's really important about sleep is that it doesn't arise from a single structure within the brain, but is to some extent a network property, and if we flip the brain on its back--i love this little bit of spinal cord here--this bit here is the hypothalamus, and right under there is a whole raft of interesting structures, not least the biological clock.the biological clock tells us when it's good to be up, when it's good to be asleep, and what that structure does is interact with a whole raft of other areas within the hypothalamus，the

lateral

hypothalamus，the ventrolateral preoptic nuclei.all of those combine, and they send projections down to the brain stem here.the brain stem then projects forward and bathes the cortex, this wonderfully wrinkly bit over here, with neurotransmitters that keep us awake and essentially provide us with our consciousness.so sleep arises from a whole raft of different interactions within the brain, and essentially, sleep is turned on and off as a result of a range of

okay.so where have we got to? we've said that sleep is complicated and it takes 32 years of our life.but what i haven't explained is what sleep is about.so why do we sleep? and it won't surprise any of you that, of course, the scientists, we don't have a consensus.there are dozens of different ideas about why we sleep, and i'm going to outline three of those.the first is sort of the restoration idea, and it's somewhat intuitive.essentially, all the stuff we've burned up during the day, we restore, we replace, we rebuild during the night.and indeed, as an explanation, it goes back to aristotle, so that's, what, 2,300 years ago.it's gone in and out of fashion.it's fashionable at the moment because what's been shown is that within the brain, a whole raft of genes have been shown to be turned on only during sleep, and those genes are associated with restoration and metabolic pathways.so there's good evidence for the whole restoration hypothesis.what about energy conservation? again, perhaps intuitive.you essentially sleep to save calories.now, when you do the sums, though, it doesn't really pan out.if you compare an individual who has slept at night, or stayed awake and hasn't moved very much, the energy saving of sleeping is about 110 calories a night.now, that's the equivalent of a hot dog bun.now, i would say that a hot dog bun is kind of a meager return for such a complicated and demanding behavior as sleep.so i'm less convinced by the energy conservation idea.but the third idea i'm quite attracted to, which is brain processing and memory consolidation.what we know is that, if after you've tried to learn a task, and you sleep-deprive individuals, the ability to learn that task is smashed.it's really hugely attenuated.so sleep and memory consolidation is also very important.however, it's not just the laying down of memory and recalling it.what's turned out to be really exciting is that our ability to come up with novel solutions to complex problems is hugely enhanced by a night of sleep.in fact, it's been estimated to give us a threefold advantage.sleeping at night enhances our creativity.and what seems to be going on is that, in the brain, those neural connections that are important, those synaptic connections that are important, are linked and strengthened, while those that are less important tend to fade away and be less important.okay.so we've had three explanations for why we might sleep, and i think the important thing to realize is that the details will vary, and it's probable we sleep for multiple different reasons.but sleep is not an indulgence.it's not some sort of thing that we can take on board rather casually.i think that sleep was once likened to an upgrade from economy to business class, you know, the equiavlent of.it's not even an upgrade from economy to first class.the critical thing to realize is that if you don't sleep, you don't fly.essentially, you never get there, and what's extraordinary about much of our society these days is that we are desperately sleep-deprived.so let's now look at sleep deprivation.huge sectors of society are sleep-deprived, and let's look at our sleep-o-meter.so in the 1950s, good data suggests that most of us were getting around about eight hours of sleep a night.nowadays, we sleep one and a half to two hours less every night, so we're in the six-and-a-half-hours-every-night

league.for teenagers, it's worse, much worse.they need nine hours for full brain performance, and many of them, on a school night, are only getting five hours of sleep.it's simply not enough.if we think about other sectors of society, the aged, if you are aged, then your ability to sleep in a single block is somewhat disrupted, and many sleep, again, less than five hours a night.shift work.shift work is extraordinary, perhaps 20 percent of the working population, and the body clock does not shift to the demands of working at night.it's locked onto the same light-dark cycle as the rest of us.so when the poor old shift worker is going home to try and sleep during the day, desperately tired, the body clock is saying, “wake up.this is the time to be awake.” so the quality of sleep that you get as a night shift worker is usually very poor, again in that sort of five-hour region.and then, of course, tens of millions of people suffer from jet lag.so who here has jet lag? well, my goodness gracious.well, thank you very much indeed for not falling asleep, because that's what your brain is craving.one of the things that the brain does is indulge in micro-sleeps, this involuntary falling asleep, and you have essentially no control over it.now, micro-sleeps can be sort of somewhat embarrassing, but they can also be deadly.it's been estimated that 31 percent of drivers will fall asleep at the wheel at least once in their life, and in the , the statistics are pretty good: 100,000 accidents on the freeway have been associated with tiredness, loss of vigilance, and falling asleep.a hundred thousand a year.it's extraordinary.at another level of terror, we dip into the tragic accidents at chernobyl and indeed the space shuttle challenger, which was so tragically lost.and in the investigations that followed those disasters, poor judgment as a result of extended shift work and loss of vigilance and tiredness was attributed to a big chunk of those disasters.so when you're tired, and you lack sleep, you have poor memory, you have poor creativity, you have increased impulsiveness, and you have overall poor judgment.but my friends, it's so much worse than that.(laughter)

if you are a tired brain, the brain is craving things to wake it up.so drugs, stimulants.caffeine represents the stimulant of choice across much of the western world.much of the day is fueled by caffeine, and if you're a really naughty tired brain, nicotine.and of course, you're fueling the waking state with these stimulants, and then of course it gets to 11 o'clock at night, and the brain says to itself, “ah, well actually, i need to be asleep fairly shortly.what do we do about that when i'm feeling completely wired?” well, of course, you then resort to alcohol.now alcohol, short-term, you know, once or twice, to use to mildly sedate you, can be very useful.it can actually ease the sleep transition.but what you must be so aware of is that alcohol doesn't provide sleep, a biological mimic for sleep.it sedates you.so it actually harms some of the neural proccessing that's going on during memory consolidation and memory recall.so it's a short-term acute measure, but for goodness sake, don't become addicted to alcohol as a way of getting to sleep every night.another connection between loss of sleep is weight gain.if you sleep around about five hours or less every night, then you have a 50 percent likelihood of being obese.what's the connection here? well, sleep loss seems to give rise to the release of the hormone ghrelin, the hunger hormone.ghrelin is released.it gets to the brain.the brain says, “i need carbohydrates,” and what it does is seek out carbohydrates and particularly sugars.so there's a link between tiredness and the metabolic predisposition for weight gain.stress.tired people are massively stressed.and one of the things of stress, of course, is loss of memory, which is what i sort of just then had a little lapse of.but stress is so much more.so if you're acutely stressed, not a great problem, but it's sustained stress associated with sleep loss that's the problem.so sustained stress leads to suppressed immunity, and so tired people tend to have higher rates of overall infection, and there's some very good studies showing that shift workers, for example, have higher rates of cancer.increased levels of stress throw glucose into the circulation.glucose becomes a dominant part of the vasculature and essentially you become glucose intolerant.therefore, diabetes 2.stress increases cardiovascular disease as a result of raising blood pressure.so there's a whole raft of things associated with sleep loss that are more than just a mildly impaired brain, which is where i think most people think that sleep loss resides.so at this point in the talk, this is a nice time to think, well, do you think on the whole i'm getting enough sleep? so a quick show of hands.who feels that they're getting enough sleep here? oh.well, that's pretty impressive.good.we'll talk more about that later, about what are your tips.so most of us, of course, ask the question, “well, how do i know whether i'm getting enough sleep?” well, it's not rocket science.if you need an alarm clock to get you out of bed in the morning, if you are taking a long time to get up, if you need lots of stimulants, if you're grumpy, if you're irritable, if you're told by your work colleagues that you're looking tired and irritable, chances are you are sleep-deprived.listen to them.listen to yourself.what do you do? well--and this is slightly offensive--sleep for dummies: make your bedroom a haven for sleep.the first critical thing is make it as dark as you possibly can, and also make it slightly cool.very important.actually, reduce your amount of light exposure at least half an hour before you go to bed.light increases levels of alertness and will delay sleep.what's the last thing that most of us do before we go to bed? we stand in a massively lit bathroom looking into the mirror cleaning our teeth.it's the worst thing we can possibly do before we went to sleep.turn off those mobile phones.turn off those computers.turn off all of those things that are also going to excite the brain.try not to drink caffeine too late in the day, ideally not after lunch.now, we've set about reducing light exposure before you go to bed, but light exposure in the morning is very good at setting the biological clock to the light-dark cycle.so seek out morning light.basically, listen to yourself.wind down.do those sorts of things that you know are going to ease you off into the honey-heavy dew of slumber.okay.that's some facts.what about some myths?

teenagers are lazy.no.poor things.they have a biological predisposition to go to bed late and get up late, so give them a break.we need eight hours of sleep a night.that's an average.some people need more.some people need less.and what you need to do is listen to your body.do you need that much or do you need more? simple as that.old people need less sleep.not true.the sleep demands of the aged do not go down.essentially, sleep fragments and becomes less robust, but sleep requirements do not go down.and the fourth myth is, early to bed, early to rise makes a man healthy, wealthy and wise.well that's wrong at so many different levels.(laughter)there is no, no evidence that getting up early and going to bed early gives you more wealth at all.there's no difference in socioeconomic status.in my experience, the only difference between morning people and evening people is that those people that get up in the morning early are just horribly smug.(laughter)(applause)

okay.so for the last part, the last few minutes, what i want to do is change gears and talk about some really new, breaking areas of neuroscience, which is the association between mental health, mental illness and sleep disruption.we've known for 130 years that in severe mental illness, there is always, always sleep disruption, but it's been largely ignored.in the 1970s, when people started to think about this again, they said, “yes, well, of course you have sleep disruption in schizophrenia because they're on anti-psychotics.it's the anti-psychotics causing the sleep problems,” ignoring the fact that for a hundred years previously, sleep disruption

had

been

reported

before anti-psychotics.so what's going on? lots of groups, several groups are studying conditions like depression, schizophrenia and bipolar, and what's going on in terms of sleep disruption.we have a big study which we published last year on schizophrenia, and the data were quite extraordinary.in those individuals with schizophrenia, much of the time, they were awake during the night phase and then they were asleep during the day.other groups showed no 24-hour patterns whatsoever.their sleep was absolutely smashed.and some had no ability to regulate their sleep by the light-dark cycle.they were getting up later and later and later and later each night.it was smashed.so what's going on? and the really exciting news is that mental illness and sleep are not simply associated but they are physically linked within the brain.the neural networks that predispose you to normal sleep, give you normal sleep, and those that give you normal mental health are overlapping.and what's the evidence for that? well, genes that have been shown to be very important in the generation of normal sleep, when mutated, when changed, also predispose individuals to mental health problems.and last year, we published a study which showed that a gene that's been linked to schizophrenia, which, when mutated, also smashes the sleep.so we have evidence of a genuine mechanistic overlap between these two important systems.other work flowed from these studies.the first was that sleep disruption actually precedes certain types of mental illness, and we've shown that in those young individuals who are at high risk of developing bipolar disorder, they already have a sleep abnormality prior to any clinical diagnosis of bipolar.the other bit of data was that sleep disruption may actually exacerbate, make worse the mental illness state.my colleague dan freeman has used a range of agents which have stabilized sleep and reduced levels of paranoia in those individuals by 50 percent.so what have we got? we've got, in these connections, some really exciting things.in terms of the neuroscience, by understanding the neuroscience of these two systems, we're really beginning to understand how both sleep and mental illness are generated and regulated within the brain.the second area is that if we can use sleep and sleep disruption as an early warning signal, then we have the chance of going in.if we know that these individuals are vulnerable, early intervention then becomes possible.and the third, which i think is the most exciting, is that we can think of the sleep centers within the brain as a new therapeutic target.stabilize sleep in those individuals who are vulnerable, we can certainly make them healthier, but also alleviate some of the appalling symptoms of mental illness.so let me just finish.what i started by saying is take sleep seriously.our attitudes toward sleep are so very different from a pre-industrial age, when we were almost wrapped in a duvet.we used to understand intuitively the importance of sleep.and this isn't some sort of crystal-waving nonsense.this is a pragmatic response to good health.if you have good sleep, it increases your concentration, attention, decision-making, creativity, social skills, health.if you get sleep, it reduces your mood changes, your stress, your levels of anger, your impulsivity, and your tendency to drink and take drugs.and we finished by saying that an understanding of the neuroscience of sleep is really informing the way we think about some of the causes of mental illness, and indeed is providing us new ways to treat these incredibly debilitating conditions.jim butcher, the fantasy writer, said, “sleep is god.go worship.” and i can only recommend that you do the same.thank you for your attention.(applause)

第四篇：人為什么要學(xué)習(xí)——5.4演講稿

人為什么要學(xué)習(xí)？

尊敬的各位領(lǐng)導(dǎo)、評委、朋友們：

大家好，我演講的題目是《人為什么要學(xué)習(xí)？》

在演講前，請各位欣賞一幅圖片：這是西安郵電大學(xué)的雕像，一男一女手挽手，女生拿書，男生托一地球，主題是智慧之源，但是有才的中國人能解讀出另一個含義：讀書頂個球。一座雕像兩種解讀，雖有玩笑成分，但不可謂不寓意深刻。

很多走出大學(xué)，步入社會的學(xué)生，他們從事與專業(yè)不對口的工作，或者是在專業(yè)學(xué)習(xí)的其他領(lǐng)域取得成就，所以會感慨說以前學(xué)的沒多大用。但是從古到今勸人多讀書的名言警句多不勝數(shù)?！吧賶巡慌?，老大徒傷悲”，“黑發(fā)不知勤學(xué)早，白發(fā)方悔讀書遲”，“莫等閑，白了少年頭，空悲切”。難道是時代變了，學(xué)習(xí)已經(jīng)跟不上潮流？——面對兩種截然不同的觀點，我們不禁要反思：人為什么要學(xué)習(xí)？

看到在座的各位，我突然有了答案：如果不會算數(shù)，不會寫公文，不會分析判斷，不會處理事件，不會交流和溝通，各位還有機會坐在這里為人民服務(wù)嗎？學(xué)習(xí)是為了掌握技能，是生存的手段，是進步的階梯。

1個月前我們鎮(zhèn)3位同事憑優(yōu)異成績進入內(nèi)江市第四批優(yōu)秀干部人才遞進培養(yǎng)班接受學(xué)習(xí)。人才遞進培養(yǎng)班，顧名思義，學(xué)習(xí)會給他們更多選擇的權(quán)利和更多成長進步的機會，我在這里也祝愿他們在今后的路途中能走得更好、更遠(yuǎn)。古話說“鳥欲高飛先振翅，人求上進先讀書”，“世事洞明皆學(xué)問，人情練達(dá)即文章”。人的一生那么長，世界變化那么大，如果妄想用在校學(xué)習(xí)的二十年去應(yīng)對未來變幻的六十年也未免太天真，如果說學(xué)習(xí)僅限于專業(yè)知識與技能，那學(xué)習(xí)未免太刻板，太狹隘。學(xué)習(xí)不僅僅是桌前的挑燈夜戰(zhàn)，學(xué)習(xí)可以是一次機遇，一回講話，一次提醒，也可以是一位人，一件事，一次感悟。在便民服務(wù)中心工作期間我曾遇到反復(fù)來詢問自己撫恤金的一位老復(fù)員軍人?！盀槭裁村X還沒到賬啊，怎么別人比我的多呀，我可是參加過抗美援朝的……”。遇到這種情況，我們會解釋安撫并幫助他，對吧？但老人嘮叨起來讓年輕的同志很為難。倒是有位老同事會有一搭沒一搭地跟他嘮嗑?！袄先思夷闵眢w真是健康，你子女呢？生活怎么樣啊？”一來二去，兩人相談勝歡，十幾分鐘后老人滿足地回家了！老同事的幾句溫言細(xì)語化解了一場可能火星撞地球的激烈碰撞，“活到老，學(xué)到老”，跟身邊人學(xué)習(xí)，確實令感觸頗多——工作多點愛心，多點耐心，群眾對政府的滿意度自然就能夠提高，干群關(guān)系會更和諧。學(xué)習(xí)不拘于形式，不拘于時間，不拘于地點，它能使你像海棉一樣不斷壯大成熟。

拋開個人不談，中國近代發(fā)展史是一部血淚史，也是一部學(xué)習(xí)史、進步史。1840年，西方國家用炮彈轟開了閉關(guān)鎖國的清朝大門，使國家飽經(jīng)滄桑，人民吃盡苦頭，這也迫使中國人開眼看世界，學(xué)習(xí)西方先進知識、法治制度、人文理念。經(jīng)277年的艱苦卓絕，頑強奮斗，中國取得巨大進步，神舟上天，航母下水，政治、經(jīng)濟、科技等領(lǐng)域取得突破性成就，群眾生活有了翻天覆地的變化。

血的教訓(xùn)告訴我們：落后就要挨打，唯有學(xué)習(xí)是進步之梯，成功之鑰，發(fā)展之機。唯有學(xué)習(xí)，我們才能成長，才能甩開膀子，邁開步子，為實現(xiàn)“兩個一百年”，實現(xiàn)“中國夢”的偉大理想而奮斗！

我的演講完畢，謝謝！

第五篇：三分鐘演講稿要怎么寫

導(dǎo)語：如何巧妙地開展好課前三分鐘活動，巧妙地利用課前三分鐘，可作為改進教學(xué)方式，增強學(xué)生學(xué)習(xí)興趣，提高教學(xué)質(zhì)量的一個突破口。三分鐘演講稿要怎么寫？下面由小編為大家整理的三分鐘演講稿范文，希望可以幫助到大家！

三分鐘演講稿范文（1）

敬愛的陳老師、親愛的同學(xué)們：

大家好！

今天是我課前三分鐘演講的時候了。在基督降生3XX年以前，有一個古希臘大政治家，雄辯家，是一個真正變態(tài)的家伙，不信，請允許我用他真實的經(jīng)歷給你們一一介紹！

德摩斯梯尼天生就是一個聲音微弱、吐字不清而又氣喘的人，（可以想象，他真是可憐?。┯绕涫恰皉 ”這個字母，他怎么說也說不清楚，而且他的發(fā)音比剛學(xué)會說話的小孩還更糟糕！

據(jù)說，他為了克服這些唇齒上的缺陷，便把石頭含在嘴里不斷的練習(xí)發(fā)音，他站在海邊練習(xí)，想把滔滔波浪喊得平靜下來，你們說他變態(tài)吧？

當(dāng)他站在臺上面對聽眾演講時，他經(jīng)歷了無數(shù)次的失敗，尤其是在他第一次嘗試演講時，他的語句全混亂了，聽眾們都放聲大笑。為了提高自己演講能力，他特意挖了一個地洞，每天在里面練習(xí)他的聲音，和演說的姿勢，他還將自己的頭發(fā)剃去了半邊，以此來控制自己想上街的欲望。德摩斯梯尼的堅持終于取得了成果，他成為了自古以來古希臘最偉大的演說家之一。

這個故事告訴我們，一個人的缺陷有時就是上蒼給他的成功信息的暗示，一個人的弱點可以成為他一生中最大的激勵因素，也可成為你消沉膽怯的借口。當(dāng)?shù)履λ固莩咴诤∈訒r，當(dāng)他在海邊、在洞坑里的時候，心里肯定依舊在想，我要變態(tài)！我要超越常人狀態(tài)，在幾十年后，他將會說：“如此的這種的變態(tài)，怎么可能不成功？！

愛迪生在發(fā)明燈泡過程中，經(jīng)歷了1萬多次失敗，；可口可樂公司開張第一年反銷出了400瓶可口可樂；創(chuàng)立迪士尼樂園的沃樂特迪士尼在報社工作曾以“缺乏創(chuàng)意”被開除；超級球星喬丹曾被所在的中學(xué)籃球球隊除名；瑞弗。約翰遜，十項全能的冠軍，有一只腳先天畸形。

當(dāng)他們完成了各項偉業(yè)的時候，他們一定會說：如此的這種變態(tài)，怎么可能不成功？

三分鐘演講稿范文（2）

敬愛的陳老師、親愛的同學(xué)們：

大家好！我今天演講的題目是《論實干》。

實干，顧名思義，就是實實在在的干，一步一個腳印腳踏實地的干。像老黃兔一樣埋下頭來做自己事情，就是實干。

如果你想成功，那么你就得實干。實實在在做有用的事情。如果每天喊口號似的，我要做多少題目，要看多少頁書，而不付出行動的，那么，我可以肯定告訴你，成功一定不會青睞你。因為你是活在口號中，而不是活在實干中。大家應(yīng)該都知道王進喜的事跡。在石油要從油井中噴出的緊要關(guān)頭，如果他不用身體去和水泥，而是站在旁邊干著急，結(jié)果有會是怎樣？眾所周知，魏書生先生是一個偉大的教育家。請大家假想一下，假如魏老師做的和說的不一樣，結(jié)果有會是怎樣？肯定的，如果他們不去實干，不付出行動，那么他們就不會成功。

實干，造就了一代代成功人物。在科學(xué)技術(shù)經(jīng)濟水平不斷發(fā)展的今天，實干尤為重要。如果不是醫(yī)務(wù)工作者的實干，sas就不會這么快被攻克；如果不是廣大人民群眾的實干，我們今天的生活就不會這么好。

在我們的學(xué)習(xí)中也是如此，那些基礎(chǔ)知識扎實，平時肯實干的同學(xué)，成績就會好。相反的，那些平時沒事做，整天生活在口號當(dāng)中，一到考試就臨時抱佛腳的人，成績就會差。所以在學(xué)習(xí)當(dāng)中，我們一定要實干，多做實事，少喊口好。只有實實在在的做有用的事，知識才會一點點的積累，學(xué)識才會一步步的提高。

為了自己理想的實現(xiàn)。為了在高考場上一舉奪魁。我們必須從現(xiàn)在起踏踏實實走路。日計劃、周計劃、月計劃，我們要一個個的落實。不能讓它們成為一紙空文。當(dāng)天的學(xué)習(xí)任務(wù)要當(dāng)天完成，不能推遲。要做到說了算，定了干，一不做，二不休。知識點要一個一個過關(guān)。學(xué)習(xí)是一個持恒的過程。每天的學(xué)習(xí)，我們不僅要落到實處而且要持之以恒的做下去。這樣才會有明顯的效果。就像我們寫《創(chuàng)新日記》一樣。

“實干”二字，說出口容易，寫出來也不難，難就難在其意：實實在在的干。而且要不得持之以恒的干，尤其是在學(xué)習(xí)方面。誰能夠持之以恒的踏踏實實的學(xué)習(xí)，誰就是最后的勝利者。

實干如同一葉船槳，推動著我們不斷前行；實干如同一只螢火蟲，照亮并指引我們前行的路；實干如同一只信鴿，帶著我們夢想飛向遠(yuǎn)方。

同學(xué)們，為了我們的理想，為了我們的班級，為了我們的第一，請投身于實干中去吧。

我的演講完畢。謝謝大家！

三分鐘演講稿范文（3）

敬愛的老師、親愛的同學(xué)們：

大家好！

如果有人問你：什么是精彩？你會怎樣回答？戰(zhàn)爭年代踴躍參軍，八十年代的文學(xué)熱，還是九十年代的出國熱？對，它們都是精彩。每個時代有每個時代的精彩，每個時代也造就了不同的精彩，但無論怎樣，精彩總是與青春緊緊相連。

記得走進大學(xué)的第一天，輔導(dǎo)員就告訴們，老狼校園民謠里輕松自如的大學(xué)生活在這個年代已經(jīng)一去不復(fù)返了。九十年代宣揚的“讀書無用論”也早已被熱火朝天的“考研”、“考證”熱吹得無影無蹤。時代已經(jīng)將新一代的青年推向了社會的最前沿。因此，要尋找屬于這一代人的精彩。

為了活得精彩，要擁有目標(biāo)和信念。目標(biāo)是心頭的一盞明燈，信念是鼓舞你向著目標(biāo)邁進的力量源泉。目標(biāo)可能飄渺，路途可能坎坷。然而只要確定一盞明燈，就能讓你順利地泅過危難的海洋！傳說中的火鳳凰，它迎著太陽飛翔，為的就是將自己的身體點燃，因為只有燃燒才能重生。這多少有一些悲壯。但又確是一幅壯美畫面。因為奮斗拼搏的過程無比精彩！

為了活得精彩，必須擁有知識和技能。知識是成功的基礎(chǔ)，技能是實現(xiàn)成功的工具。人類步入二十一世紀(jì)，世界多極化，信息全球化，知識信息量在以百倍的速度遞增。面對這樣的現(xiàn)實，昔日象牙塔里輕松自在的場景早已不見，取而代之的是尋找精彩的一雙雙熾熱的目光。社會將競爭的殘酷帶到了的身邊，從而也造就了新一代青年的自強和向上。有一句話說“機遇留給有所準(zhǔn)備的人”，那么，年青的朋友們，讓早早準(zhǔn)備。

為了活得精彩，還要有不斷超越的精神。魯迅先生曾說，“不滿是向上的靈魂”。時代的進步使新事物以讓人難以置信的速度發(fā)展。沒什么鐵飯碗，沒什么保質(zhì)期。無論什么時候，都必須以起跑線上的姿態(tài)去迎接挑戰(zhàn)。只有不斷地學(xué)習(xí)和提高，才能跟得上這個精彩的大時代。

永遠(yuǎn)究竟有多遠(yuǎn)？沒有人知道。只是歷史長河中的小小一滴水。然而既是青春的擁有者，就沒有理由不為自己喝彩，沒有理由不活得精彩！都將老去，但不是為了永遠(yuǎn)的青春而來，而是為了感受和不同的青春而來。從現(xiàn)在開始，讓活得精彩！

謝謝大家！
