The growth of population during the past few centuries is no proof that population will continue to grow straight upward toward infinity and doom. On the contrary, demographic history offers evidence that population growth has not been at all constant. According to paleoecologist Edward Deevey, the past million years show three momentous changes. The first, a rapid increase in population around one m illion B. C., followed the innovations of tool making and tool using. But when the new power from the use of tools has been exploited, the rate of world population growth fell and became almost stable. The next rapid jump in population started perhaps 10,000 years ago, when mankind began to keep herds, plow and plant the earth. Once again when initial productivity gains had been absorbed, the rate of population growth abated. These two episodes suggest that the third great change, the present rapid growth, which began in the West between 250 and 350 years ago, may also slow down when, or if, technology begins to yield fewer innovations. Of course, the current knowledge revolution may continue without foreseeable end. Either way - contrary to popular belief in constant geometric growth - population can be expected in the long run to adjust to productivity. And when one takes this view, population growth is seen to represent economic progress and human triumph rather than social failure.

You have got all that the great have had: two arms, two legs, two hands, two eyes, and a brain to use if you'd be wise. With this equipment they all began, so start for the top and say" I can". Look them over the wise and the great. They take their food from a common plate. With similar knives and forks they use; with similar laces they tie their shoes. The world considers them brave and smart, but you know--- you have got all they had when they made their start. You can triumph and come to skill; you can be great if you only will. You are well equipped for the fight you choose you have arms and legs and brains to use. And people who have risen, great deeds to do started their lives with no more than you.

God has equipped you for life, but he lets you decide what you want to be.

People say they'd like to do this or that,but...then they offer all the excuses in the world why they can't do whatever it is.No matter what the excuses are,the only thing usually limiting them is their own self-perception. If I've learned anyhing,I've learned a person--any person--can do just about anything they set their mind to.The only thing they need is a willingness to work for what you want,patience to learn what you need to know,and just a little bit of belief in yourself,but you only need a seed.Your faith in yourself will grow with you as you move forward. If you self-perception is that you can't accompilsh somthing because you're not smart enough,then take the time to learn what you need to know and your self-perception will change. If your self-perception is that you can't accompilsh something because you never finsh anything you start,then go finsh something and change your self-perception. If your self-perception is that you're too lazy,too bust,too unworthy,too unfocused,too depressed,too dependent on others,the you're right.You are that because you believe that,but you can change that! Life is change,and the past doesn't equal the future.Your today is the result of your past beliefs and actions.Change your beliefs and action and you change your future.If you think you can or you can't,you're right.You are what you think.

超级正能量晨读励志文章 个世界唯一不变的真理就是变化，任何优势都是暂时的。当你在占有这个优势时，必须争取主动，再占据下一个优势，这需要前瞻的决断力，需要的是智慧!下面由小编与大家分享超级正能量晨读励志文章，希望你们喜欢!欢迎阅读! 励志文章1：人生就像巧克力 我很喜欢阿甘正传里的一句话“生命就像一盒各式各样的巧克力，你永远不会知道自己会得到什么。”阿甘是个有点轻度智障的美国人，他的母亲自小训练他要乐观、正面的面对人生，所以不管面对什么样的环境，他都能够苦尽甘来，有人说那是电影，即便是现实中真的有这种人，那也是运气好而己，但真的是如此吗? 那世界首富比尔盖茨呢?也是运气好，那么多软件公司，只有他运气特别好，其他人运气都不好，真的是这样的吗?很多人把自己的成就归功于自己的能力，而把失败归因于运气不好，其实人生中真的没有失败，只有暂时停止成功，只有放弃，才是真正的失败，运气就好比是春、夏、秋、冬一般是轮流替换的。只要不放弃，目前的情况都只是暂时的，总会有解决的方法。 正面思考的定义的是，在遇到挑战或挫折时，人们会产生“解决问题”的企图心，并找出方法正面迎接挑战。反之，负面思考就是一遇到挫折，人们就被负面情绪打败，而责怪自己、环境，最后选择退缩、放弃或报复。问问你自己，你是属于正面思考或是负面思考的人，那将决定你的未来。 不管是经营家庭、感情、事业、健康怀抱着正面积极思考的心态是很重要的，不要抱怨、责怪，这个世界上每个人都有不同的问题，如果你觉得自己不幸，那么想想海伦凯勒，生下来不久就眼瞎、耳聋、口哑，如果你跟她交换身份，你愿意吗?人生有顺境与逆境，但重点是你要如何的面对你的人生，是用积极乐观的思维或是怨天尤人的角度，这个答案在你这儿，旁人无法为你作决定，毕竟是你要经营自己的人生，那为何不改变思路，从现在开始训练自己用积极、乐观的思考来面对生命中的每一天。 励志文章2：别为今天感到挫折
晨读英语美文100篇 Passage1. Knowledge and Virtue Knowledge is one thing, virtue is another; good sense is not conscience, refinement is not humility, nor is largeness and justness of view faith. Philosophy, however enlightened, however profound, gives no command over the passions, no influential motives, no vivifying principles. Liberal Education makes not the Christian, not the Catholic, but the gentleman. It is well to be a gentleman, it is well to have a cultivated intellect, a delicate taste, a candid, equitable, dispassionate mind, a noble and courteous bearing in the conduct of life—these are the connatural qualities of a large knowledge;they are the objects of a University.I am advocating, I shall illustrate and insist upon them;but still, I repeat, they are no guarantee for sanctity or even for conscientiousness,and they may attach to the man of the world, to the profligate,to the heartless, pleasant, alas, and attractive as he shows when decked out in them.Taken by themselves, they do but seem to be what they are not;they look like virtue at a distance, but they are detected by close observers, and in the long run;and hence it is that they are popularly accused of pretense and hypocrisy,not, I repeat, from
Chapter One Human Life Like a Poem 人生如诗 I think that, from a biological standpoint, human life almost reads like a poem.我以为，从生物学角度看，人的一生恰如诗歌。 It has its own rhythm and beat, its internal cycles of growth and decay. 人生自有其韵律和节奏，自有内在的生成与衰亡。 No one can say that a life with childhood, manhood and old age is not a beautiful arrangement; 人生有童年、少年和老年，谁也不能否认这是一种美好的安排， the day has its morning, noon and sunset, and the year has its seasons, and it is good 一天要有清晨、正午和日落，一年要有四季之分，如此才好。 that it is so. There is no good or bad in life, except what is good according to its own season. 人生本无好坏之分，只是各个季节有各自的好处。 And if we take this biological view of life and try to live according to the seasons, no one but a conceited fool or an impossible idealist can deny that human life can be lived like a poem. 如若我们持此种生物学的观点，并循着季节去生活，除了狂妄自大的傻瓜和无可救药的理想主义者，谁能说人生不能像诗一般度过呢。 ——Lin Yutang 1.We Are on a Journey人在旅途 By Henry Van Dyke Wherever you are, and whoever you maybe, there is one thing in which you and I are just alike at this moment, and in all the moments of our existence. We are not at rest; we are on a journey, our life is a movement, a tendency, a steady, ceaseless progress towards an unseen goal. We are gaining something, or losing something, everyday. Even when our position and our character seem to remain precisely the same, they are changing. For the mere advance of time is a change. It is not the same thing to have a bare field in January and in July, the season makes the difference. The limitations that are childlike in the child are childish in the man. 无论你在何处，无论你是何人，此刻，而且在我们生命的每时每刻，你与我有一点是类似的。我们不是在休息，我们在旅途中。生命是一种运动，一种趋势，一个稳步、持续的通往一个未知目标的过程。每天，我们都在获得，或失去。尽管我们的地位和性格看起来好像一点都没变，但是它们在变化。因为时光的流逝本身是一种变化。在一月和七月拥有一片贫瘠的土地是不同的，是季节本身带来了变化。孩童时可爱的缺点到了成人时便成了幼稚。
Passage 1. knowledge and Virtue 知识和美德 Knowledge is one thing, virtue is another知识是一件事,美德是另一回事; good sense is not conscience, refinement is not humility,正确的判断力并非意识,文雅并非谦逊, nor is largeness and justness of view faith.广博与正义的观点也并非信仰 Philosophy, however enlightened, however profound,哲学,无论多么富有启迪,然而深刻 gives no command over the passions, no influential motives, no vivifying principles.都无法驾驭情感,不具备有影响力的动机,不具有灵活的原则。 Liberal Education makes not the Christian, not the Catholic, but the gentleman.自由教育并不造就基督徒,天主教徒,而是绅士。 It is well to be a gentleman,好的造就一个绅士, it is well to have a cultivated intellect, a delicate taste, 最好有一个有教养的思维,具有敏锐的鉴赏力, a candid, equitable, dispassionate mind, 公正、平等、冷静的头脑, a noble and courteous bearing in the conduct of life 一种高尚的行为礼貌的轴承的生活 —these are the connatural qualities of a large knowledge; 这些都是在大固有的品质知识 they are the objects of a University. 他们的对象的大学 I am advocating, I shall illustrate and insist upon them; 我提倡,我将解释和坚持他们 but still, I repeat, they are no guarantee for sanctity or even for conscientiousness, 然而,我重复一遍,他们是不会保证没有责任感,或者甚至是婚姻的神圣性 and they may attach to the man of the world, to the profligate, 他们可能会在世界的人,对挥霍无度 to the heartless, pleasant, alas, and attractive as he shows when decked out in them. 因为在他们那里显示是无情的,舒适,悲伤,和有吸引力的。 Taken by themselves, they do but seem to be what they are not; 被自己,他们只是似乎是他们没有做； they look like virtue at a distance, but they are detected by close observers, and in the long run; 他们看起来像美德在远处的,但是他们是通过近距离的观察发现,在长期内看来； and hence it is that they are popularly accused of pretense and hypocrisy, 是不可能的,因此,他们被指控虚伪是普遍和虚伪， not, I repeat, from their own fault, 再说一次,我,从自己的错， but because their professors and their admirers persist in taking them for what they are not, 因为他们的教授和他们的仰慕者坚持采取他们不去做， and are officious in arrogating for them a praise to which they have no claim. 给他们冒称爱管闲事的在赞美,他们没有权利要求这样。 Quarry the granite rock with razors, or moor the vessel with a thread of silk,采石场用剃刀就可以开采出花岗岩,或摩尔人血管丝绸的一根线 then may you hope with such keen and delicate instruments as human knowledge 便可你希望这样的激烈,精密的仪器作为人类知识 and human reason to contend against those giants, 和人类理性与斗争的巨人 the passion and the pride of man. 激情和骄傲的男人 Passage 2. “Packing” a Person "包装"一个人 A person, like a commodity, needs packaging. 恰如一件商品,人也需要包装。 But going too far is absolutely undesirable. 但切忌过分包装。 A little exaggeration, however, does no harm 稍微夸张,然而，也不会有坏处 when it shows the person's unique qualities to their advantage. 一个人要以自己的优势表现一个人的独特品质。 To display personal charm in a casual and natural way, 要在不经意中,自然地发挥个人魅力, it is important for one to have a clear knowledge of oneself. 这对每一个人对自己有了明晰的认知来说是很重要的。 A master packager knows how to integrate art and nature without any traces of embellishment, 会包装的人知道怎样将艺术与自然整合不留痕迹地去装饰,
晨读励志文章3篇 晨读励志文章留在北上广深 记得前几年我在一则报纸上看到过一篇文章，是关于出外打工像我这样的年轻人逃离北上广深回老家的事。那时候很流行的说，北上广深的房子太贵了，在这些地方长住久安老大不容易，我还是回老家吧!可是这些年你看，那些喊着这个口号的人又回到了北上广深这样的大城市。为什么呢?因为他们发现老家更没有机会。老家那才真的叫人民政府，没有人啥事也办成。相反地在北上广深这样的城市，它的制度建设相对来说比较规范，你不必需要熟人，不必投亲靠友，你就可以正常的工作和生活，这是最大的区别。 城市化意味着什么!城市化其实是一个非常简单的概念，就是陌生人的大规模肉身聚集。如果我们都不在城市，用肉身的方式聚集，不能和亲朋友约在星巴克这样的咖啡厅坐一坐，不能去串个门子拜访一下比我们优秀的人，不能在重要的决策和谈判、协商的时候，能够完成肉身的直接面对面，那么会让人类所有精细的体验合作崩溃掉。现在生活的本质，只有聚集才能产生大规模的财富。财富是怎么来的?财富是由劳动者创造的。没错，锄禾日当午，汗滴禾下土。谁知盘中餐，粒粒皆辛苦。靠辛勤的劳作，一粒汗珠掉地上摔八半，这可以创造财富，但是对不起，那只是农耕文明的财富，到了工业文明的财富就不是这种形态了。比如说，英国著名学者李约瑟讲中国人发明了水
排，又发明了风箱，他为什么没有走完最后一步，把他们凑起来变成蒸汽机呢，就像我们以前经常说我们中国人最先有四大发明，比如火药，外国人都造起了枪炮，而我们国家还在放烟花鞭炮。没错，这就是聚集的最后一步你没有完成，它水排是水排，风箱就是风箱，财富没有发生，所以财富是什么，财富就是聚集的产物。打个小小比方，一小区旁如果开有商场，这小区因此房价就往上涨，因为小区的人流量，商场的生意也会变得好，所以它们搁到一块各自得了好处，这就是城市化聚集带来的财富效应。 年轻人来到城市就是要以肉身的方式到来，而不是通过一根网络线，一根电波线来了解城市，你真的以为秀才不出门，能知天下事?能，但那都是皮毛而已，不能深入骨髓。所以说以肉身的方式来到城市去身临其境的体验，这就是你未来和他人进行自由协作和你终身财富的根本源泉，你说你能离开北上广深吗? 年轻人在城市获得更多的东西其实远不仅上面说的肉身之间的沟通，更重要更关键的一个东西是“见识”。见识这玩意儿跟经济地位、跟人多聪明没多少关系，就是你是否在大城市生活。北京随便一四五岁的小男孩站在街上，什么法拉第、宾利、保时捷等各种世界品牌的豪车他都认识，他们家地库就跟国贸车展没什么区别，深圳随便一小孩几乎都去过肯德基、麦当劳、什么全国各地的美食都吃过，什么桂林米粉、螺蛳粉，什么陕西凉皮肉夹馍河南捞面等等这些，他们家楼下就是一条长长的美食街。你外地一农村的大学生，可能学问很高，但是对不起你没见识，这就是城市生活给人的灵魂世界带来最丰
星火四级晨读英语美文100篇【励志感悟】第17篇 The Power of Beauty One of the most successful, influential and beloved women in American history, Eleanor Roosevelt once said that she had one regret: she wished she had been prettier. Who hasn’t felt the same way? We are all too aware of our physical imperfections. To overcome them, we spend billions upon billions of dollars every year on cosmetics, diet products, fashion, and plastic surgery. Why do we care so much about how we look? Because it matters. Because beauty is powerful. Because even when we learn to value people mostly for being kind and wise and funny, we are still moved by beauty. No matter how much we argue against it or pretend to be immune, beauty exerts its power over us. There is simply no escape. Aristotle said, “Beauty is a greater recommendation than any letter of introduction.” It’s not fair, but it’s true. We simply treat beautiful people better than we do others. Attach a photograph of a beautiful author to an essay, and people will think that is more creative and more intelligently written than exactly the same essay accompanied by the photo of a homely author. Our sensitivity to physical beauty is not something we can control at will. We are born with it. Experiments conducted by psychologist Judith J. Langlois showed that even small infants prefer to look at attractive faces. Before they have met a single supermodel, before they have watched a single TV show, before they have opened up a single fashion magazine, they are drawn to the same faces which adults have judged to be attractive. There are more important things in life than beauty. But as Etcoff says, “We have to understand beauty, or we will always be enslaved by it.” If you aim to be wise and kind and funny, it doesn’t mean that you can’t also try your best to look beautiful. There’s no reason to feel guilty about being moved by beauty’s power. It moves us all. 翻译： 美的力量 身为美国史上最成功、最有影响力且最受人喜爱的女性之一的罗斯福夫人曾说她有一个遗憾：她希望自己长得更漂亮。谁没有过同样的想法呢？我们都强烈感觉到自己身体的缺陷。为了克服缺陷，我们每年都要花费几十亿美元--在化妆品、减肥食品、流行时尚与整容手术上。 我们如此这么在意自己的外貌？因为它很重要。因为美的力量很大。因为即使我们学着基本上去看重仁慈、智能、风趣的人，但我们仍会受到美的感动。无论我们多么用力辩驳，或假装对它免疫，美仍然对我们产生影响。根本无法逃避。 亚里斯多德说：“美是比任何介绍信都要有用的推荐函。”这并不公平，但却是事实。我们就是会对美丽的人比较好。把一位美丽作家的照片贴在作品上，读者就会认为这篇文章较有创意，写得更有智能。完全相同的文章配上相貌平凡的作家照片，评价就会较低。 我们对外在美的敏感，不是可以控制自如的。我们天生就这么敏感。心理学家朱迪丝蓝洛斯的实验显示，就连小婴儿也喜欢看漂亮的脸。他们从来没有见过超级名模、没看过电视节目，也没翻开过时尚杂志，却已经受到大人也认为有魅力的脸庞所吸引。 人生中有比美丽更重要的事，但就如艾特考夫所说：“我们必须了解美，否则我们永远都会是它的奴隶。”如果你的目标是要聪明、仁慈又风趣，这并不代表你就不能尽力让自己变得漂亮。被美的力量感动，并不需要有罪恶感，因为所有的人都受它感动。
14. Beauty of July七月之美 By Alice Meynell One has the leisure of July for perceiving all the differences of the green of leaves. It is no longer a difference in degrees of maturity, for all the trees have darkened to their final tone, and stand in their differences of character and not of mere date. Almost all the green is grave, not sad and not dull. It has a darkened and a daily colour, in majestic but not obvious harmony with dark grey skies, and might look, to inconstant eyes, as prosaic after spring as eleven o'clock looks after the dawn. 七月间，人们有余暇观察树叶绿翠的千差万别。这不再是成熟上的差异，因为所有的树木，或转苍翠，或呈墨绿，色调均已固着定格，从而展现出来的，并非时节上的不同，而是各自品格上的差异。几乎各种绿色，品味凝重，既不流于悒郁，也不失之沉闷，它具有一种深沉、日常的色泽，与灰暗的苍穹浑然一体，构成庄重却非一眼可见的和谐，故而在游览扫掠的目光看来，可能会有阳春繁景过后的平淡之感。一如黎明之后十一点的光景。 Gravity is the word---not solemnity as towards evening, nor menace as at night. The daylight trees of July are signs of common beauty, common freshness, and a mystery familiar and abiding as night and day. In childhood we all have a more exalted sense of dawn and summer sunrise than we ever fully retain or quite recover; and also a far-higher sensibility for April and April evenings---a heartache for them, which in riper years is gradually and irretrievably consoled. 凝重，乃是最贴切的字眼——不是时近黄昏的阴沉，亦非黑夜之中的森然。七月白昼的葱郁树木，体现出普通的美，常见的清新，是一种如同黑夜白昼般惯常而又永恒不变的不解之谜。童年时代，我们看到黎明和夏天日出盛景，会油然生出一股日后无法充分保留、也难以完全恢复的奋激狂喜；同时，对四月和四月的日暮黄昏，还产生一种陶然忘情的欣赏共鸣——一种为之怦然心动的神驰向往，进入壮年之后，又无可挽回地逐渐淡化平息。 But, on the other hand, childhood has so quickly learned to find daily things tedious, and familiar things importunate, that it has no great delight in the mere middle of the day, and feels weariness of the summer that has ceased to change visibly. The poetry of mere day and of late summer becomes perceptible to mature eyes that have long ceased to be sated, have taken leave of weariness, and cannot now find anything in nature too familiar; eyes which have, indeed, lost sight of the further awe of midsummer daybreak, and no longer see so much of the past in April twilight as they saw when they had no past; but which look freshly at the dailiness of green summer, of early afternoon, of every sky of any form that comes to pass, and of the darkened elms. 只有阅历丰富的慧眼，才能感受到白昼本身的夏末时令固有的诗意——这双慧眼已久未获满足矣，同时也摆脱了厌倦感，此刻发现在自然界，即使最常见的景物也另有一番情趣；诚然，面对仲夏红日的喷薄欲出，已不再萌发敬畏之情；凝望四月的苍茫暮色，也不会比一无阅历的童年，引发更多的联想，然而，对司空见惯的日常景象——树木葱茏的盛夏，日过中天的午后，来而复去、变幻不定的每一片云天，还有幽暗的榆树——反倒会投以新的目光。
