i'm going to try and explain why it is that perhaps we don't understand as much as we think we do. i'd like to begin with four questions. this is not some sort of cultural thing for the time of year. that's an in-joke, by the way.

我会试着解释为何我们知道的东西很可能并没有我们自以为知道的多我想从四个问题开始,不是那种今年流行的文化问题对了，刚刚那句是个圈内笑话

but these four questions, actually, are ones that people who even know quite a lot about science find quite hard. and they're questions that i've asked of science television producers, of audiences of science educators -- so that's science teachers -- and also of seven-year-olds, and i find that the seven-year-olds do marginally better than the other audiences, which is somewhat surprising.

不过这四个问题，事实上即使是很懂科学的人也会觉得很难应答我拿这些问题去问科学节目制片人问那些有科学教育背景的观众也问教科学的老师还有七岁孩童我发现七岁孩童答得比其他人好这是有些令人惊讶

so the first question, and you might want to write this down, either on a bit of paper, physically, or a virtual piece of paper in your head. and, for viewers at home, you can try this as well.

第一个问题，我建议你把问题记下来抄在纸上，或想像中的纸上坐在电脑前的你也可以试著作答.

a little seed weighs next to nothing and a tree weighs a lot, right? i think we agree on that. where does the tree get the stuff that makes up this chair, right? where does all this stuff come from?

种籽很轻，而大树很重，是吗?我想我们都同意吧，大树用来制成椅子的东西是从哪来的? 对吧?这些东西都是怎么来的?

(knocks)

(敲椅声)

and your next question is, can you light a little torch-bulb with a battery, a bulb and one piece of wire? and would you be able to, kind of, draw a -- you don't have to draw the diagram, but would you be able to draw the diagram, if you had to do it? or would you just say, that's actually not possible?

问题二，你能否点亮一个小灯泡只用1个电池、1个灯泡、和1条电线? 那你能画出上述问题的图解吗?不用真的画但如果需要的话，你能画出来吗? 还是你会说这个不可能?

the third question is, why is it hotter in summer than in winter? i think we can probably agree that it is hotter in summer than in winter, but why? and finally, would you be able to -- and you can sort of scribble it, if you like -- scribble a plan diagram of the solar system, showing the shape of the planets' orbits? would you be able to do that? and if you can, just scribble a pattern.

第三个问题，为什么夏天比冬天热? 大家应该都同意夏天比冬天还热但为何如此?最后，你能不能简单的勾勒出太阳系的平面图... 呈现出行星轨道运行的形状你可以画得出来吗? 你画得出来的话，就把形状画出来

ok. now, children get their ideas not from teachers, as teachers often think, but actually from common sense, from experience of the world around them, from all the things that go on between them and their peers, and their carers, and their parents, and all of that. experience. and one of the great experts in this field, of course, was, bless him, cardinal wolsey. be very careful what you get into people's heads because it's virtually impossible to shift it afterwards, right?

好，孩童对事物的概念不是老师教的老师时常这么以为，但实际上概念来自于常理来自于孩童对周遭世界的体验来自于他们跟同伴彼此交流还有跟保姆、父母亲、所有人交流的经验这个领域中的一个专家，对了，愿他安息就是渥西主教，他说要你将东西放进其他人的闹袋里的时候要小心因为那些东西几乎不会再改变，对吧?

(laughter)

(笑声)

i'm not quite sure how he died, actually. was he beheaded in the end, or hung?

我不太清楚他的死因，真的他最后上了断头台?还是被吊死?

(laughter)

(笑声)

now, those questions, which, of course, you've got right, and you haven't been conferring, and so on. and i -- you know, normally, i would pick people out and humiliate, but maybe not in this instance.

现在回到那四个问题，大家都知道是什么问题了你们彼此之间也没有讨论答案我平时习惯点人站起来回答让他丢脸不过这次就不点了

a little seed weighs a lot and, basically, all this stuff, 99 percent of this stuff, came out of the air. now, i guarantee that about 85 percent of you, or maybe it's fewer at ted, will have said it comes out of the ground. and some people, probably two of you, will come up and argue with me afterwards, and say that actually, it comes out of the ground. now, if that was true, we'd have trucks going round the country, filling people's gardens in with soil, it'd be a fantastic business. but, actually, we don't do that. the mass of this comes out of the air. now, i passed all my biology exams in britain. i passed them really well, but i still came out of school thinking that that stuff came out of the ground.

种籽可以很重，基本上所有的这些 99%都来自于空气我相信有85%的人，或许在你们ted会比较少会说木材来自于大地，而有些人也许你们中的一两位，可能结束后会来找我争论说木材其实是来自于大地若是如此，那我们就会有让卡车跑来跑去把人们的花园都填上土，那会是很棒的生意。不过实际上我们不会那么做因为木材的材料大部分其实是从空气中来的我在英国念书时考生物每考必过我的成绩很好，但毕业后还是以为木材来自于大地

second one: can you light a little torch-bulb with a battery bulb and one piece of wire? yes, you can, and i'll show you in a second how to do that. now, i have some rather bad news, which is that i had a piece of video that i was about to show you, which unfortunately -- the sound doesn't work in this room, so i'm going to describe to you, in true "monty python" fashion, what happens in the video. and in the video, a group of researchers go to mit on graduation day. we chose mit because, obviously, that's a very long way away from here, and you wouldn't mind too much, but it sort of works the same way in britain and in the west coast of the usa. and we asked them these questions, and we asked those questions of science graduates, and they couldn't answer them. and so, there's a whole lot of people saying, "i'd be very surprised if you told me that this came out of the air. that's very surprising to me." and those are science graduates. and we intercut it with, "we are the premier science university in the world," because of british-like hubris.

你能用一枚电池和一根电线点亮灯泡吗? 是，你可以，我会示范怎么做。不过，现在有个坏消息本来有个影片要给大家看可惜在这边声音放不出来所以我就口头描述一下的，用巨蟒剧团的表演方式，影片内容是这样的，在影片里有一群研究员在毕业典礼那天去麻省理工学院为什么是麻省理工呢?因为它离这里很远大家也就不会太介意不过场景设在英国结果也差不多或是设在美国西岸我们问了麻省理工的毕业生这四个问题这些理工科毕业生也答不出来而且还有很多学生表示我很惊讶你说木材是从空气中来的这真的让我很吃惊，那些理工的毕业生这么说我们用我们是全球第一的理工大学来作影片的结尾。因为英国人很傲慢

(laughter)

(笑声)

and when we gave graduate engineers that question, they said it couldn't be done. and when we gave them a battery, and a piece of wire, and a bulb, and said, "can you do it?" they couldn't do it. right? and that's no different from imperial college in london, by the way, it's not some sort of anti-american thing going on.

我们拿第二个问题去问硕士毕业的工程师们他们说这不可能做得到我们拿了电池、电线、和灯泡问他们你能做到吗?，他们没办法，是吧? 顺道一提，伦敦的帝国学院的情况估计也差不多如此我们不是在做什么反美的事

as if. now, the reason this matters is we pay lots and lots of money for teaching people -- we might as well get it right. and there are also some societal reasons why we might want people to understand what it is that's happening in photosynthesis. for example, one half of the carbon equation is how much we emit, and the other half of the carbon equation, as i'm very conscious as a trustee of kew, is how much things soak up, and they soak up carbon dioxide out of the atmosphere.

虽然听来颇像。问题的关键是我们花了很多钱来教育大众，我们应该正确地来做这件事。其中也有一些社会因素让我们想使大众了解光合作用如何运作例如，有一半的碳储量是人类排放的而另一半碳储量我相当关切，身为皇家植物园的受托管理人

that's what plants actually do for a living. and, for any finnish people in the audience, this is a finnish pun: we are, both literally and metaphorically, skating on thin ice if we don't understand that kind of thing.now, here's how you do the battery and the bulb. it's so easy, isn't it? of course, you all knew that. but if you haven't played with a battery and a bulb, if you've only seen a circuit diagram, you might not be able to do that, and that's one of the problems.

是植物吸收多少二氧化碳植物就是以此维生的如果在场有芬兰人，这是芬兰话的双关语我们无论在实际上或隐喻上，都是如履薄冰要是我们不明白那些事电池和灯泡只要这要做就行很简单，不是吗?你们都懂了但要是你没有亲手碰过电池和灯泡如果你只看过电路图你可能就做不出来，这是个麻烦

so, why is it hotter in summer than in winter? we learn, as children, that you get closer to something that's hot, and it burns you. it's a very powerful bit of learning, and it happens pretty early on. by extension, we think to ourselves, "why it's hotter in summer than in winter must be because we're closer to the sun." i promise you that most of you will have got that. oh, you're all shaking your heads, but only a few of you are shaking your heads very firmly.

那么，为何夏天比冬天热? 我们从小就知道，离热的东西太近你就被烫到，这真很有效的教育方法很小的时候大家就学到了延伸这个论点，我们觉得夏天比冬天热一定是因为我们离太阳比较近我相信大多人都懂了哦，大家都在摇头不过只有几个人摇得很坚定

other ones are kind of going like this. all right. it's hotter in summer than in winter because the rays from the sun are spread out more, right, because of the tilt of the earth. and if you think the tilt is tilting us closer, no, it isn't. the sun is 93 million miles away, and we're tilting like this, right? it makes no odds. in fact, in the northern hemisphere, we're further from the sun in summer, as it happens, but it makes no odds, the difference.

其他人只是这样子摇而已，好吧夏天比冬天热是因为太阳的辐射线传播得比较多，地球倾斜的关系如果你以为是朝太阳的方向倾斜，那就错了太阳离地球1亿5千万公里，地球倾斜角度大略如此倾斜不是差别所在，在北半球夏天时我们离太阳更远跟倾斜没有关系

ok, now, the scribble of the diagram of the solar system. if you believe, as most of you probably do, that it's hotter in summer than in winter because we're closer to the sun, you must have drawn an ellipse. right? that would explain it, right? except, in your -- you're nodding -- now, in your ellipse, have you thought, "well, what happens during the night?"

好，问题四是画出太阳系的平面图如果大家相信，大多数可能都相信夏天比冬天热是因为地球离太阳较近大家应该都画了椭圆形对吧?这就能解释了吧? 除非，你点头了，你画了个椭圆形你有想过，「夜晚又是怎么回事」?

between australia and here, right, they've got summer and we've got winter, and what -- does the earth kind of rush towards the sun at night, and then rush back again? i mean, it's a very strange thing going on, and we hold these two models in our head, of what's right and what isn't right, and we do that, as human beings, in all sorts of fields.

澳洲和美国这边，澳洲是夏天这边是冬天，难道说地球在晚上会冲向太阳然后再冲回来?这实在很奇怪我们脑中有两种思考模式，对的和错的身为人类，我们在很多领域都这样思考

so, here's copernicus' view of what the solar system looked like as a plan. that's pretty much what you should have on your piece of paper. right? and this is nasa's view. they're stunningly similar. i hope you notice the coincidence here.

左边是哥白尼画的太阳系平面图跟你们纸上画的差不多，对吧右边是nasa的版本，两张图非常相似我希望大家注意其中的巧合要是你知道人们有错误观念

what would you do if you knew that people had this misconception, right, in their heads, of elliptical orbits caused by our experiences as children? what sort of diagram would you show them of the solar system, to show that it's not really like that? you'd show them something like this, wouldn't you? it's a plan, looking down from above. but, no, look what i found in the textbooks. that's what you show people, right?

你会怎么做在他们脑中，楕圆形的轨道是他们儿时经验教的吗? 你会给他们看什么样的太阳系示意图? 证明太阳系不是他们想的那样你会给他们看这种图吗? 这是俯瞰的平面图可是并非如此，瞧瞧我在教科书里找到的你会给他们看这种图对吧?

these are from textbooks, from websites, educational websites -- and almost anything you pick up is like that. and the reason it's like that is because it's dead boring to have a load of concentric circles, whereas that's much more exciting, to look at something at that angle, isn't it? right?

出自教科书出自教育网站你找得到的几乎都是这种图会以这种视角呈现是因为只有一堆同心圆太死板无趣从这种视角看太阳系比较新鲜刺激不是吗?

and by doing it at that angle, if you've got that misconception in your head, then that two-dimensional representation of a three-dimensional thing will be ellipses. so you've -- it's crap, isn't it really? as we say.

因为弄成这种视角如果你脑中有了这种误解用二度空间来呈现三度空间就会变成椭圆形这真是糟糕，可不是吗?

so, these mental models -- we look for evidence that reinforces our models. we do this, of course, with matters of race, and politics, and everything else, and we do it in science as well. so we look, just look -- and scientists do it, constantly -- we look for evidence that reinforces our models, and some folks are just all too able and willing to provide the evidence that reinforces the models.

因此，我们寻求证据来增强我们的心智模式我们用这种方式处理种族、政治、所有事当然也用这种方式处理科学，我们只观看是科学家在这么做，我们不断寻求证据来增强我们的心智模式，有些人很有办法也乐意提供证据来增强那些模式

so, being i'm in the united states, i'll have a dig at the europeans. these are examples of what i would say is bad practice in science teaching centers.

所以我现在人在美国，就会说欧洲人的坏话这些图片都是我认为不良的科学教育

these pictures are from la villette in france and the welcome wing of the science museum in london. and, if you look at the, kind of the way these things are constructed, there's a lot of mediation by glass, and it's very blue, and kind of professional -- in that way that, you know, woody allen comes up from under the sheets in that scene in "annie hall," and said, "god, that's so professional." and that you don't -- there's no passion in it, and it's not hands on, right, and, you know, pun intended.

类似教学中心，这些图取自法国维叶特科博馆以及伦敦科博馆的迎宾翼展示区你看看这些东西建成的模样有很多玻璃隔板，蓝光色调，弄得很专业似的那种方式，就像是伍迪艾伦从床单里冒出来在《安妮霍尔》戏中的那一幕他说老天，这真是太专业了这其中没有热情，没有动手参与，是吗这是个双关，不过也有好的教学方法

whereas good interpretation -- i'll use an example from nearby -- is san francisco exploratorium, where all the things that -- the demonstrations, and so on, are made out of everyday objects that children can understand, it's very hands-on, and they can engage with, and experiment with. and i know that if the graduates at mit and in the imperial college in london had had the battery and the wire and the bit of stuff, and you know, been able to do it, they would have learned how it actually works, rather than thinking that they follow circuit diagrams and can't do it. so good interpretation is more about things that are bodged and stuffed and of my world, right? and things that -- where there isn't an extra barrier of a piece of glass or machined titanium, and it all looks fantastic, ok?

我举一个例子，离这里很近，旧金山探索馆在那里所有的东西，展示品之类的都是用孩子能懂的日常用品做成的都可以动手玩，孩子们可以专心玩好好体验我知道麻省理工毕业生以及伦敦帝国学院毕业生手上有电池电线点亮灯泡的话他们会明白其中的原理而不是觉得他们照着电路图来做是做不到的好的教学方法不是沉溺陶醉在自己世界里对吧? 那些东西也不该被隔着用玻璃或是钛制品隔开看起来很漂亮就好，好吗?

and the exploratorium does that really, really well. and it's amateur, but amateur in the best sense, in other words, the root of the word being of love and passion.

旧金山探索馆在这点做得非常好看上去很业余，但业余得很对头也就是说，根本的出发点是出自爱和热情

so, children are not empty vessels, ok?so, as "monty python" would have it, this is a bit lord privy seal to say so, but this is -- children are not empty vessels.

所以，孩童不是空瓶子用巨蟒剧团的说法就是有点像英国掌玺大臣会说的意思是说孩童不是空无一物的瓶子

they come with their own ideas and their own theories, and unless you work with those, then you won't be able to shift them, right?

他们生来就有自己的想法和理念如果你没从这些地方着手，就改变不了他们对吧?

and i probably haven't shifted your ideas of how the world and universe operates, either. but this applies, equally, to matters of trying to sell new technology.

我大概没有改变大家的想法对于世界和宇宙到底如何运作不过这些道理同样可以用在推销新科技上也

for example, we are, in britain, we're trying to do a digital switchover of the whole population into digital technology [for television].

例如，在英国，我们试着把全部的电视都换成新科技的数位电视

and it's one of the difficult things is that when people have preconceptions of how it all works, it's quite difficult to shift those.

有个难题是人们对事物运作的方式一旦有了成见就很难去改变

so we're not empty vessels; the mental models that we have as children persist into adulthood. poor teaching actually does more harm than good.

我们不是空瓶子，我们保有心智模式从幼年到成年一直都存在不良的教学是弊多于利

in this country and in britain, magnetism is understood better by children before they've been to school than afterwards, ok? same for gravity, two concepts, so it's -- which is quite humbling, as a, you know, if you're a teacher, and you look before and after, that's quite worrying. they do worse in tests afterwards, after the teaching.

在美国和英国，在磁力知识上孩童在就学前学得比较好重力知识也一样，两个不同概念，这实在可悲如果你是个老师，看见受教前和受教后的差别实在令人忧心，学童在受教后考得更差

and we collude. we design tests, or at least in britain, so that people pass them. right? and governments do very well. they pat themselves on the back. ok?

我们都是共犯，我们设计测验方式至少在英国是这样，好让人们能通过考试政府也帮了不少忙，他们推波助澜懂吗?

we collude, and actually if you -- if someone had designed a test for me when i was doing my biology exams, to really understand, to see whether i'd understood more than just kind of putting starch and iodine together and seeing it go blue, and really understood that plants took their mass out of the air, then i might have done better at science. so the most important thing is to get people to articulate their models.

我们都是共犯如果有人替我设计测验在我要考生物的时候让我能真正明白，明白我是否真的懂了不是只在淀粉中加入碘液看着反应呈现蓝色而且能真正明白植物是从空气中茁壮的我的科学可能就会学得比较好所以，最重要的是要让人们能表述清楚他们的模型

your homework is -- you know, how does an aircraft's wing create lift? an obvious question, and you'll have an answer now in your heads. and the second question to that then is, ensure you've explained how it is that planes can fly upside down. ah ha, right.

回家作业是，机翼是怎样帮助飞机起飞的? 这问题很好懂，大家心中也有答案了注意事项是你要确保自己能解释为何飞机头向下的时候也能飞，对吧

second question is, why is the sea blue? all right? and you've all got an idea in your head of the answer. so, why is it blue on cloudy days? ah, see.

问题二，海为何是蓝色的? 大家心中应该都有答案了那么，为什么阴天时海还是蓝的?看吧 (笑声) 我一直想在美国讲这句话

(laughter)

(笑声)

i've always wanted to say that in this country. (laughter) finally, my plea to you is to allow yourselves, and your children, and anyone you know, to kind of fiddle with stuff, because it's by fiddling with things that you, you know, you complement your other learning. it's not a replacement, it's just part of learning that's important. thank you very much. now -- oh, oh yeah, go on then, go on.

最后，我希望大家能让自己，还有孩子以及任何你认识的人，去动手接触事物因为亲自接触了事物，你知道的你就补足了其他方面的学习不足，这不是替换这只是学习中很重要的一部分谢谢大家那么，噢，没关系，继续吧

(applause)

(鼓掌)

每个人在现实生活中都会遇到坎坷与波折，逢迎尴尬的局面，此时不知你是如何面对和应付，不知你是否在迷茫中看到那真诚的微笑和永恒的臂膀。

20xx年7月28日同事的孩子升学举办宴会致邀宾朋，临时抬爱我为主持，说实在的学生的活动没少组织，但那是按程序要求来的，可这种大型的宴会还真没有机会尝试。我深知主人的信任，也知道自己肩负的使命，所以当时就与主人沟通，在头脑中构思宴会的程序，按主人的意愿上午11：28分宴会正式开始，需要我做的只是把主人的感激之情传达，无需其他形式，一切活动从简，就是让来客吃好喝好，所以在我的头脑中就形成了这样的一套方案，鸣放礼炮、主持人小序铺垫、引出主人致答谢、推出主角孩子答谢、大家开杯共饮、升学者敬酒后主持活动结束。从我一个非专业人士的眼光也就这些活动足矣。当天我按程序到11：28分时我正式开始主持召开宴会，但令我不安的是不知道什么原因，在我解说的时候，我发现菜迟迟上不来，所以我放慢了语速，而且其中添加了不少深入人心感激的话语，主人被闪亮请出致答谢，主角被请出隆重致辞。但此时一道菜也没有上来。当麦克风再一次传回到我的手中的时候，汗水伴着不安同时从心里涌出，我知道此时冷场将意味着什么，我知道主持人是画龙点睛之笔，而不是来演讲或作报告的，大家来是喝酒吃饭的，不是来听我唠叨的，这我在其他宴会上也曾经历过，有过亲身的感受。此时来几首唱歌吗!可是主人没有要求过。今天在这激动人心的时刻，能遇到这么多的高朋贵友，我真是感到非常的荣幸，同时在您的面前我也感到了一丝丝的紧张。此时别人可以不言语，但是麦克风是绝对不能让它无声的啊!为了圆场我又一次恭维起了来客，显然明智和经过场面的人已经看出了端倪。我们永远支持你寻声望去，是一位衣着考究四十来岁的来客，这句话真是掷地有声啊!而且他给我做了一个ok的手势，微笑着向我点了点头，我顿然感到了有一股火热的感觉在身体里燃烧。谢谢!非常感谢各位朋友的支持!我深深鞠了一个躬以礼回谢，此时我的大脑一刻都没有停止运转，思考着如何打破着僵局，听了那位先生的鼓励话语，收获了他真诚的笑脸，我感到灵感马上就光顾了，我何不借花献佛，分级别祝福一下各位来宾呢?一张张真诚的笑脸，一双双饱含深情的眼睛，一颗颗火红跳动的心，铸就了我们爱的长城。上班族、买卖阶级、农民朋友、在校学生、小朋友我分别用简洁豪情的话语来祝愿他们。当时我也不知道哪里涌来的这么多言辞。在我讲话之时，我看到酒菜终于上桌了，一颗悬着的心终于放了下来。斟满美酒，共同举杯，容纳所有的祝福与希望!干杯——在大家喝酒夹菜的时候我暂时的结束了主持的活动，在我放下麦克风的时候，我不由感激地回头看看刚才说话的那位朋友，他同样用和蔼可亲的目光微笑着看了看我，同时举了一下酒杯，我知道他的善意，当时我感到他无声中带有一种磁力。后来听说那位先生是某司仪协会副主席专业庆典主持人，因为当时忙与其他应酬，所以不能为我的同事做主持人，而且他还再三嘱咐主人，不要在众人面前暴露他的身份。我想不用多说大家都应该明白他的用意，我的理解就是个人优秀的修养与高尚的职业道德。

宴会已经结束好久了，可是那张真诚的笑脸，那双饱含情意的双眼，仿佛镌刻在我的心里，我想这是由我心底所激荡的心潮，让我终生不能忘记。微笑对于我们自身来说太廉价了，可面对像我这样需要帮助的人来说又是多么的昂贵。一句话，一丝微笑可以改变一个世界，可以挽救一个生命，微笑是我们生命中的太阳给予我们温暖，微笑是我们成长中的力量赋予我们坚强，微笑是我们沟通的信使架起我们友谊的纽带和桥梁，为了让世界更美丽，让人生更精彩，为了让我们的人生更辉煌，请您奉献您的微笑，让我们用微笑面对人生和世界。

ted的演讲稿篇3

尊敬的老师，亲爱的同学们大家好，我是理学院__级应用化学1班的王兴兴，很荣幸有机会站在这里和大家一起谈谈我走过的大学，相对于在座的其他几位同学，如果是学习、工作、科技竞赛、实践、课余生活其中的某一方面来我做得都没有他们好，唯一觉得可以说的是我在这几个方面都有一定的收获与感悟，能够协调好自己的精力与时间，全面地发展。在这里我就谈谈在走过的路途中我是如何得到进步与提高的。

首先我提出几个问题，在刚进大学的时候，我们或多或少都会被问及这样的问题：第一个：到大学里来你是干什么的?现在作为大一的你们能否为这个问题给自己一个答案?能不能?第二：当我们知道或者意识到自己想做什么的时候，也就是有了方向，我们接下来怎么做?朝着朝阳一路狂奔，即使路边的野花有多么的漂亮也不去理会?是这样吗?最后：在你狂奔的路上问题也不少啊，哪天学习又紧，工作也迫在眉睫，朋友们也在这个时候想起你啦，你能不学习?能不工作?能不义气?不能啊，这时你该干嘛?很简单嘛——该干嘛干嘛。

问题完了，同学们在思考，我也在思考，思考我曾经遇到这类问题时我是怎么做的，现在该怎样和大家一起分享。

大一第一学期，我沉默了一学期，也就是什么也没做，没人知道会有我这个人存在，就像晒干了的茶叶，蜷缩着。下学期，开始把部分精力投放到工作上，在工作中找到乐趣，做任何事都不会觉得累和烦，踏踏实实地去完成每一件事，即使是一个小细节，也从不马虎，记得大二上一次，统计学生成绩，在e_crl里面做，那时e_crl不太熟练，只能慢慢来，一个一个输入，一个一个计算，计算一遍检查一遍，两个表格做到半夜很晚。不是因为第二天急需要表，而是在面对一件事情的时候，我有一种提前去完成的冲动，事情都不要等到截止了才匆匆忙忙地赶，结果错误百出。后面的工作中我组织了很多活动，期中包括运动会，晚会，各种学院比赛和竞赛等等，由于工作比较认真负责，也被评为学校的优秀学生干部。对于我这个过程也就像是茶叶泡在了水里，慢慢地舒展开来。

到了大二，生活开始丰富起来，学习课程不见少，实验每周做两门，在这期间我参加了挑战杯和全国大学生数学建模竞赛，奖没获多少，可我却是在这上面受益匪浅。我做挑战杯的时候，我和班上两个同学一组，每天除了上课就待在实验室，待了一个月的时间，那段时间中毒不少，数据每天测三四次，定时侧，每隔六个小时，一天测四次，那就是早晨6点，中午12点，下午6点，晚上12点，这样也可以避免和上课的冲突。有时候早晨起床校园里一个人都没有，连吃早餐的地方也没有，早餐一般是晚上准备好的面包，晚上回去寝室同学都睡下了，只能“偷偷地”洗漱然后爬上床躺下，躺下后再总结一下一天的实验，想想哪里有没有问题，有没有遗漏什么。做实验整个的思路得我们自己去想，还得和同学讨论交流，中间我们还因为一些实验细节，争吵过，有一次甚至差点放弃实验，当然最后实验是继续的，不仅如此我们之间消除矛盾，能更好地合作，关系也得到巩固。通过实验改变了我的许多观念，各方面能力也得到了训练。在后面的数模中，我是和其他学院我的两个好朋友一起做的，同样收获了不少。

对于学习，正如我上面问及的问题，到大学里来你是干什么的?用我们老师的语调来回答就是：你是学生，你的任务还是学习，对吧。只要明白这样一个道理，你在学习上就算是成功了一半，剩下的一半就是你能否有计划高效率地学下去了，对于我自己，现在在每个月初我都会写下这个月的学习计划，然后对应分配到每周的计划，每一天也有一定的要求，不过综合各方面原因我是拿不了国家奖学金的，只能拿个国家励志。

课外生活中，刚进大学的时候，我给自己下了一个任务，每两周看一本书，什么书都可以，根据自己的兴趣爱好定，问同学借、图书馆借、自己买的，我看书的兴趣也会在一段时间一段时间地改变，因此看书的种类也就比较多，包括经管类的，宗教、哲学、教育学、中外的文学和小说，还有一些名著。虽然是理工科男生，不过我一直都比较喜欢的还是哲学和文学。同学们在大学里有资源有时间就可以多看看书，最好少玩一会游戏，我电脑里是一个游戏也没有的，我认为那样是太浪费时间了，不过对于部分同学，可以适当去玩一会，但一定要把握好一个度。

我的经历也就这样，希望亲爱的同学们能在自己的大学里回答好前面的几个问题，在以后的大学生活中走得自然、顺畅。这里我就冒昧地提出三点小建议：

首先，大学就是要使自己的大学生活大起来，生活得充实，丰富多彩，路边的野花该采还得采哈。

其次，有效地安排时间;有效运筹时间是一种可以学习的技能。善用时间的人往往有一些好习惯，例如拟定长短计划，以比较实际的观点安排自己的时间和计划，还有一点很重要就是有效地利用时间休息。

再次，切实定下重要计划完成的期限;把重要计划分成几部分。这样的好处是：1使事情变得比较容易处理;2每完成一小步，你就有成就感;3更容易跟踪自己的进度;4可以避免超之过急(在短时间内做完一大堆事情)或到最后一分钟才匆匆赶工。

然后，特别是作为我们学生一定要培养起团结合作的精神，一定要有集体荣誉感，在我看来一个即使个人再优秀，但是脱离了集体，他还是失败的。

最后，借用王国维的三境界与亲爱的同学们共勉："昨夜西风凋碧树。独上高楼，望尽天涯路。"此第一境界。“衣带渐宽终不悔，为伊消得人憔悴。”此第二境界。“众里寻他千百度，蓦然回头，那人却在灯火阑珊处。”此第三境界。三句话的意思大家自己多多理解。

谢谢!

ted的演讲稿篇4

尊敬的老师，亲爱的同学们：

大家好!

人的一生如同四季：春耕、夏种、秋收、冬藏。

四季不断更替轮回，阳光与温暖却无时不在，温暖着我的身体自更温暖着我的心灵。

零乱的碎片在脑海中飘落，似成熟的果实，慢慢地汇成一幅明晰的图画，演绎出一段永恒的回忆，此生决不会模糊，我坚信。

小时候，在我的灵魂深处有一种载体记录人生的轨迹，或深或浅，它就驻在那，永生不灭，它叫记忆与爱。

母亲、外婆、外公总是喜欢坐在阳光喜微处，细细地品味着他们无法忘怀的年华。我、我弟、我妹一时好奇安静地听他们畅谈，一时闹得天翻地覆，这个画面里总少不了无拘无束的阵阵笑声。这个画面里最抢眼的要算外公了，一双写满沧桑的手，上面爬满了一个个无情的茧，但他健壮的体魄与炯炯有神的大眼睛凸显出他的活力。只见他说得“雨水”四溅，手舞足蹈，时而深情地望着身旁的妻子与儿女，时而用并不悦耳的嗓音叮嘱我们注意安全。这是一段令人刻骨铭心的温馨回忆。

年年岁岁花相似，岁岁年年人不同。时光无情，新的时代已在悄然无声中列表，每个人都失去了往日的悠闲，为了过上更好的生活，求学与求职是必不可少的途径。人们各自忙着自己的事，老人们它更是闲不下来，庄稼大片大片地栽种，新鲜绿色蔬菜水果第一时间带给子女们，只要儿女们回一趟家，或仅仅只是一个电话，都会让他们高兴好几天。

年复一年，日复一日，又到了春节。这时不管工作怎么忙大家都会回家团聚，这应该是老人家们最开心的时光了吧!“外公、外公，给我一个打火机咯，我想玩鞭炮”。我那稚嫩的童声脆脆响起，只见外公脸上露出严肃的表情，“小孩子不可以玩火的，要是不小心伤到了怎么办!”我不敢抬头看他严肃的脸，但贪玩之心谁也阻挡不了，我赌气地跑到各个房间去找打火机。一阵翻箱倒柜，在把房间里的东西弄得一片狼藉之后，打火机终于现身了。我迅速找到我的“实验室”，“实验材料”一切准备就绪，只待引燃，内心充满挑战前的快意。最终我的手、头发、眉毛、眼皮也都成了试验品。那时的我并没有意识到危险性，只是感到一阵痛楚随后席卷而来，随后哭声尖利刺耳，几米外的外公手里还拿着扫帚，就如一个百米冲刺的运动员，满脸通红地冲到我面前，我并没有感到害怕，看到外公这么紧张反而倍感幸福。他为我微微哈气拂去我的伤痛，细细抚慰，句句暖心，它让我懂得，心有多宽爱就有多深。

时隔几年，情深未变。

美丽的幻想总会遭遇残酷的现实。

就在前几天，我打电话回家，母亲一听到我的声音，一阵压抑的哽咽从电话那头传来，我预感有什么事情发生，在我的一再追问下，妈妈告诉我，外公去长沙了，他的病很严重，令人揪心的消息就那么猝不及防地传来了。我放下电话，只觉胸口堵得慌，那可是日夜深爱我、牵挂我的人啊，我又何尝不是日夜牵挂着他呢?

蜡烛的美，是绝唱的美，它以自焚的痛苦将自己化为光与热，照亮了别人。

外公，我说过带你游历千山万水，去各个国家的博物馆，我还没有实现我的诺言呢，你不会不给我机会吧?那么多那么多的爱你全部付出，那么多那么多的苦你一个人扛着，粗糙的手支起了整个家，厚实的背为我们挡住风雨。小时候，你温和的话语与坚实的脊背伴随着我度过无数个日日夜夜，长大了，你尽你所能呵护着我，就算有一天你的记忆走远了，但爱不会，它会在儿孙的臂膀上一代代传承。

此刻，我在为你祈祷，我在为你祈祷!就算是为了我，外公，你也一定要坚持。请你给我一个感恩的机会，如果可以，我真的愿意折寿十年来换取你的重生。在你有限的生命里，我会尽我所能，还你一个温暖的晚年。

日子一天天翻过去，旧事如纸页般也一页页地淡去。

昔日为生活写下的文字也随着岁月的消磨而变得淡淡泛黄，有些模糊不清。就像我现在的生活一样，每天都过的那么平淡，如水一般的淡。淡的极至便是一种模糊。

不是刻意想去改变什么，也不是刻意想去追求什么，只是想让自己的每一天能过得充实，仅此而已。然而，我却始终找不到一个希望的方向。

我钟爱前进，却在此刻停下了脚步。我仿佛站在了一个莫大的十字路口。失去了希望的方向，失去了前进的激情。可以做的只有原地不停的徘徊。

有的人笑话我，“你有病啊!装什么深沉?”

有的人关心我，“已经是大二了，你还在迷茫啊!时间不多了，赶紧努力吧!”

我都沉默地听着，心里却苦于没人能懂的无奈。

生活的迷茫谁人能避开?如果你告诉我你可以，那只能说明：你没有用心去生活!

生活是一杯酒。有它本质的苦涩，也有它本质的醇香。你可以尝出它的醇香，却不一定能品出它的苦涩。两种味道的完美结合，才是生活的真谛。你忘了苏大词人著名的词句了吗?“人有悲欢离合，月有阴晴圆缺。”我想苏大词人想表达的亦在：生活不只有欢乐幸福，同样存在悲伤痛苦。

20__年一晃眼，过去了三分之一。还没来得及整理过新春的悠闲，时间就扑面而来，接着迎风而去，没有半点声音。05年我遗失了很多东西，06年我亦得到了很多东西;05年有些人从我身边走了，06年有些又来到了我的身边。不再为失去的东西感伤，也不再为得到的东西而欣喜若狂。生活就是这样。这个冬末里最后飘落的一枚枫叶上刻着我对失去的东西和失去的人的无尽思念。愿这份思念能长久地牵着你连着我。

生活还在继续。

我没有理由也不可能逃避生活的迷惘。享受了生活给我的欢乐幸福，我也会承受生活给我的悲伤痛苦。

逃避，是一种怯懦，一种后退。

一个让自己失望的人，肯定会让他身旁的人失望，生活亦就失去了应有的激情与光彩。一个能给自己带希望的人，也会给身边的人带来希望，生活才有了意义。

人，应该为希望而活着。

虽然在十字路口徘徊，但我没有失去对前进的渴望。一旦找到了希望的方向，我便会大步前行。

此时此刻，生活告诉了我：它是一种责任，一种对别人也是对自己的责任。

老师们、同学们：

早上好！

今天国旗下讲话的主题是《吃出健康》。

随着生活水平的提高，健康已成为我们追求的目标。每年的5月20日是“全国学生营养日”。合理的饮食对于我们小学生的身心健康和成长发育是十分重要的，是我们学习和生活的基本保证。可是，我们经常看到一些同学遇到自己喜欢的菜才吃，不喜欢的菜就不动筷子了；有些同学还把方便面、羊肉串等“垃圾食品”当成自己的最爱。这样长期下去会造成了膳食结构单一，影响体能与智力发展，甚至还会引发许多健康问题。

怎样才能吃出健康呢？首先我们要重视一日三餐，做到定时、定量、合理搭配，遵循“早饭吃好、午饭吃饱、晚饭吃少”的原则。保证好一日三餐外，我们还应注意以下几方面：

1、注意饮食卫生。我们要做好个人卫生外，还要做到不去路边摊点买吃的。

2、少吃油炸食品，远离“方便面”、“羊肉串”等“垃圾食品”。

3、不要挑食。遇到自己喜欢的菜我们吃，遇到不喜欢的菜我们也要吃。我们要吃鸡、鸭、鱼、肉，也要吃各种新鲜蔬菜；每天要喝足量的白开水，不喝或少喝碳酸饮料。这样我们的身体里才会有各种各样的营养，才能让我们建康成长。

同学们，希望大家，合理饮食，用最健康的体魄，最饱满的精神去迎接每一天。
