贪欲消灭人类
白鳍豚原是长江的龙头老大，居于长江水生生物食物链的顶端长达2500万年，在漫长的水域里所向披靡，但是它们最终灭绝了。上世纪80年代初种群数量为400头左右;1986年，300头;1990年，200头;1994年，100头以下;1997年，13头;1999年，5头;20xx年，生命之旗已经降落。这位长江的原始主人无声无息地消失了，在一个不为人知的时刻，完成了最后的挣扎，把最后一滴眼泪汇入了奔腾不息的万古长江。这可怕的灾难只有可能来自——人类。
上帝派了个天才来向人类透露它的绝密消息，那个叫做霍金的天才歪歪斜斜地坐在轮椅上，口齿不清地说：最后的日子，就在下个世纪。
霍金说的很对，人类末日不再遥远。
是什么导致人类的灭绝呢?
是欲望!是的，人类贪婪的欲望导致了动物的灭绝，导致了地球的变异，导致了灾难的产生，最终，贪欲将灭绝人类自己。
香格里拉人是外星人遗留在地球上的高智能物种，是他们创造了人类，并且进行了一次清除。东方佛经里所记载的乐园叫香巴拉，西方传说的乐园叫伊甸园。伊甸园中的一对男女最终被欲望驱使而犯错被驱逐出了乐园。香格里拉人制造了人类，但是人类被欲望驱使，最终繁殖过多，被香格里拉人惩罚，将人类所在的大陆沉入水底。西方人说是挪亚方舟拯救了人类，其实，那只是人类为了躲避洪灾而逃到神圣的地球最高峰——喜马拉亚山。据说进入香格里拉世界的通道在布达拉宫的底部，但是，很少有人进入。神圣的香格里拉已经抛弃了人类，这是因为，人类有贪婪的欲望，而这欲望，和传说一样，会导致人类的灭绝，而毁灭人类的工具就是——洪水。
贪婪的欲望本身就是洪水猛兽，最终，洪水猛兽将吞噬人类，吞噬人类的欲望。
你可曾发现?在局部范围，洪水越来越猛烈，不管人类科技如何进步，也无法抵抗?你可曾发现?海啸越来越猛烈，可以瞬间吞噬无数岛屿?你可曾发现?台风越来越猛烈?可以将一切都拦腰折断?你可曾发现?冬天变的如此短暂，气温升的如此快速?你可曾知道?喜马拉雅山的冰川正在融化，北极冰雪将在本世纪内消失，纽约、东京等城市将被上升的海水淹没。
还有更多你所不知道的，那深沉的海底，隐藏着太多史前的古生物，当海水逐渐上升，当城市逐渐被淹没，人类，都将成为海底猛兽的快餐。
人类的末期啊，已近在眼前。是欲望，是贪婪的欲望，最终消灭了人类自己!
各位同学大家好，我是__级美学三班的___，我的演讲题目是 《大门糊口生涯》
最终大学是我们即将进入社会去面对自力糊口生涯的一个缓冲阶段，但是进入大学后很多人的糊口生涯是盲目标，记得刚进入校园的时候，我身边有很多人在抱怨异国进入一个抱负的大学，另有些在抱怨异国抓住一次告成的爱情，另有些从大一到如今一贯为游戏猖獗着，大门糊口生涯只有这转瞬的四年韶光，这是一个你门生年代最高雅的韶光，大学四年，有多少人的四年已一去不返，不要到毕业的时候还在抱怨大学四年白上了。
有很多大门生还具有一种思维便是60分万岁，想想我们身后为我们的学业付出多少工作的父母，难道他们要的便是你各科都经过议定了60分的毕业证吗?不是的!读大学是要你明了一个搏斗目标，要你学会去自力思虑题目办理题目的本领~另有一个4年高雅的搏斗进程。大学四年其实不要求你去轰轰烈烈的去结束甚么，只要求你为一件事去竭力，去拼搏，要的是个搏斗的进程和汗水。比如你去考英语四级，一年下来你每天都坚定去早读去上晚自习，坚定看下几本书，去进修新的知识网页建造，去做社会实践活动~去表面做兼职~乃至是去果敢的追求一名女生····等等。都可以充裕你的大门糊口生涯来熬炼本身。
我发起大繁多去看看文学作品，因为文学内里讲的大多是人生哲学题目，死亡题目，呵呵~听起来大略比较可怕，但这些题目你必须得去想，文学作品看的多了你的眼界也会缓缓的进步，脑筋本领心理蒙受本领也会缓缓的进步，这有助于我们科学成长，因为文学作品里有很多都是很实际的题目，都是糊口生涯中活生生的例子，我们要学会时候具有一种危机意识去糊口生涯，因为那种紧急感会促成我们务必要去竭力搏斗。
同学们拿出实行的勇气去创设每个高雅，大四毕业的时候回头看看本身,是一个异国遗憾富裕豪情的芳华。
最终祝贺大家有一个高雅的大门糊口生涯，感谢大家!
长大以后，我只能奔跑，一边失去，一边在寻找，明天你好，即使含着泪微笑。——题记
青岛一五年的第一场雪在一中校园里纷飞，我独自站在窗口望那“鹅毛”纷纷落落，心无感触似是无稽之谈，但是要我说出那其中的感触，我只能笑而不语。不是一个人独行惯了才独自赏雪，只是认为唯有一人才能体会到一片雪花飘荡在这万千孤独的迷茫。路漫漫，及行迷之未远，归。
喧闹的环境伴随着阶梯教室那扇门打开而渐渐平息。我望着一身材平平的男人向我们走来，在无尽的掌声中向我们鞠躬，那瞬间我是木讷的，为什么如此成功之人会这般谦逊，我眯起眼，妄想从其中汲取些许。身边的朋友无一不被外籍校长抓住了眼球，而我的目光一直停留在他的身上未曾离去。随着讲座的开始，那段往事渐渐地浮现在我们的眼前。听他讲到那坎坷崎岖的路程，我的眉头不由紧皱，心也随之触痛。的确!谁能想象到一双弹钢琴的手竟然曾经承担过这般的苦痛!董荣璨博士轻松的言语讲述着他在外奔波的三十年，而那些经历牵动着台下的我们每一个人的心。还好，一切的一切都是有用的，他成为了伟大的作曲家，钢琴家，艺术家，一个大写的中国人!
崇敬在我的眼眶流露，只是隔着那遥远的距离而无法传达，那炙热的情感流露无一不表达着我对他的敬仰之情!一曲现场创作像一股暖流涌向心头，简单的音符在他的手指下编织成婉转、悠扬的曲子，飘到我们的心中飘到我们的灵魂里!我的手指不由随着节奏敲打着桌面，用心去感受其中的情感。一曲《梁祝》回荡在耳旁，其中蕴含着的是三十多年的心血和汗水，满满的感情流露让我的内心有所触动，也许那天收获的不仅仅是听觉的盛宴，也是满满的内心感动。
临近一五年的尾声，忙忙碌碌的自己也似乎找到了目标。内心怀着那份信仰，马不停蹄地走着。不做无庸的事，不做无庸的人。时光荏苒，却冲刷不掉我内心怀揣的前进的激情;白驹过隙，只希望留下的是美好的回忆。怀揣着这份信念前进，让我强忍住泪水，高昂着头前进。我不畏艰难困苦，只望见了黎明的一缕曙光便会前行，那等待我的必定是我的信仰，在最后的最后，我们会相拥，拥抱明天!
我不是作曲家，无法用跳跃的音符谱写深情;我不是钢琴家，我不会用流畅的乐章流露传情;我不是艺术家，无法用高端的美展现自己。但是我心怀理想又怎么肯轻易折服?负面、消极的全都抛之脑后，趁现在，努力给自己“艺术人生”!
长大以后，我开始奔跑，即使含着泪微笑，但不远处的斑斓星光在闪烁，那便是我的信念，明天你好!
尊敬的各位领导、亲爱家长朋友、老师们：
大家好!
又是一年教师节。今年是第29个教师节，首先，我代表幼儿园全体老师向关心支持我们的领导致以崇高的敬意!向鼎立支持幼儿园工作的家长朋友表示忠心的感谢!接下来，我要祝我们所有的老师“节日快乐!”
人们常把教师比作园丁，确实如此。当老师非常的辛苦和劳累，尤其是幼儿教师。幼教是一项耐心、持久、艰苦的工程，幼教意味着责任，汗水，配合。没有谁能够不付出辛勤汗水就能成功，没有谁脱离家长的配合就能成功。在当今重视教育，家长要求越来越高，孩子的个性越来越强的社会背景下，做一个好教师很难。我们的老师只有不断接受挑战，不断改进我们的服务态度，端正我们的工作态度，才能赢得家长的信任。也只有真心的付出和全身心的投入，才能赢得孩子的爱。
上学期，老师们都付出了辛勤的劳动，也赢得了绝大多数家长的信任。所以在本学期扩大了生源。成绩的取得离不开领导的关心和家长的支持。当然，我们的工作也存在很多的不足，比如保育工作还可以做得更细一些，教育方面，还要不断地学习与提高。如今，我们又一次步入了金秋的九月，又一次面临着新的学期新的起点，又一次面临新的挑战新的希望。报名时，当我看见家长向我们投来的一双双期望的眼神，当我看着孩子们天真无邪的眼睛，当朱港的干部，及附近农民也信任地将孩子的手交到了我们手里，我感觉任重而道远。孩子是每一个家庭的核心，幼儿园关系到千家万户，幼儿园是监狱工作的大后方之一。只有幼儿园工作做好，我们的干工才能安心、踏实地工作。在以后的日子里，我们将和孩子们一道成长。如果说我们的付出是艰辛的，孩子们的回报则是厚重的。在新学年的工作中，我们不求惊天动地，只愿平凡无悔;不求硕果累累，只愿问心无愧;不求点石成金，只愿春风化雨;不求桃李满天下，只愿笑声满园关不住!
幼儿教育离不开家长的配合，所以请家长同志在对孩子进行引导时，一定要平等相待、晓之以理，切忌出现过分宠爱，或动则呵斥、或撒手不管、或过分唠叨等现象。在师生关系上，要引导孩子尊重老师，不要用老师来吓唬幼儿。同时希望家长朋友们对我们的工作多提宝贵意见。
幼儿教育也离不开监狱领导的关心。上半年，幼儿园合并。监狱给予了幼儿园极大的支持。每个教室安装了空调，本学期又翻新了小小班教室的地板。下一步，幼儿园计划将外面两块草坪铺上塑胶地垫，再增添一套大型幼儿室外玩具，不断地改善环境。相信监狱领导会一如继往地给予支持。
其实，幼儿园就像是一个大家庭，有老师，有孩子，有爸爸妈妈。在监狱领导的大力支持下，只要我们大家团结起来，齐心协力，我们的幼儿园一定会一天比一天好!
最后，我衷心地祝愿在座的每一位，身体健康、工作顺利、生活幸福、节日快乐!
my subject today is learning. and in that spirit, i want to spring on youall a pop quiz. ready? when does learning begin? now as you ponder thatquestion, maybe you're thinking about the first day of preschool orkindergarten, the first time that kids are in a classroom with a teacher. ormaybe you've called to mind the toddler phase when children are learning how towalk and talk and use a fork. maybe you've encountered the zero-to-threemovement, which asserts that the most important years for learning are theearliest ones. and so your answer to my question would be: learning begins atbirth.
well today i want to present to you an idea that may be surprising and mayeven seem implausible, but which is supported by the latest evidence frompsychology and biology. and that is that some of the most important learning weever do happens before we're born, while we're still in the womb. now i'm ascience reporter. i write books and magazine articles. and i'm also a mother.and those two roles came together for me in a book that i wrote called"origins." "origins" is a report from the front lines of an e_citing new fieldcalled fetal origins. fetal origins is a scientific discipline that emerged justabout two decades ago, and it's based on the theory that our health andwell-being throughout our lives is crucially affected by the nine months wespend in the womb. now this theory was of more than just intellectual interestto me. i was myself pregnant while i was doing the research for the book. andone of the most fascinating insights i took from this work is that we're alllearning about the world even before we enter it.
when we hold our babies for the first time, we might imagine that they'reclean slates, unmarked by life, when in fact, they've already been shaped by usand by the particular world we live in. today i want to share with you some ofthe amazing things that scientists are discovering about what fetuses learnwhile they're still in their mothers' bellies.
first of all, they learn the sound of their mothers' voices. because soundsfrom the outside world have to travel through the mother's abdominal tissue andthrough the amniotic fluid that surrounds the fetus, the voices fetuses hear,starting around the fourth month of gestation, are muted and muffled. oneresearcher says that they probably sound a lot like the the voice of charliebrown's teacher in the old "peanuts" cartoon. but the pregnant woman's own voicereverberates through her body, reaching the fetus much more readily. and becausethe fetus is with her all the time, it hears her voice a lot. once the baby'sborn, it recognizes her voice and it prefers listening to her voice over anyoneelse's.
how can we know this? newborn babies can't do much, but one thing they'rereally good at is sucking. researchers take advantage of this fact by rigging uptwo rubber nipples, so that if a baby sucks on one, it hears a recording of itsmother's voice on a pair of headphones, and if it sucks on the other nipple, ithears a recording of a female stranger's voice. babies quickly show theirpreference by choosing the first one. scientists also take advantage of the factthat babies will slow down their sucking when something interests them andresume their fast sucking when they get bored. this is how researchersdiscovered that, after women repeatedly read aloud a section of dr. seuss' "thecat in the hat" while they were pregnant, their newborn babies recognized thatpassage when they hear it outside the womb. my favorite e_periment of this kindis the one that showed that the babies of women who watched a certain soap operaevery day during pregnancy recognized the theme song of that show once they wereborn. so fetuses are even learning about the particular language that's spokenin the world that they'll be born into.
a study published last year found that from birth, from the moment ofbirth, babies cry in the accent of their mother's native language. french babiescry on a rising note while german babies end on a falling note, imitating themelodic contours of those languages. now why would this kind of fetal learningbe useful? it may have evolved to aid the baby's survival. from the moment ofbirth, the baby responds most to the voice of the person who is most likely tocare for it -- its mother. it even makes its cries sound like the mother'slanguage, which may further endear the baby to the mother, and which may givethe baby a head start in the critical task of learning how to understand andspeak its native language.
but it's not just sounds that fetuses are learning about in utero. it'salso tastes and smells. by seven months of gestation, the fetus' taste buds arefully developed, and its olfactory receptors, which allow it to smell, arefunctioning. the flavors of the food a pregnant woman eats find their way intothe amniotic fluid, which is continuously swallowed by the fetus. babies seem toremember and prefer these tastes once they're out in the world. in onee_periment, a group of pregnant women was asked to drink a lot of carrot juiceduring their third trimester of pregnancy, while another group of pregnant womendrank only water. si_ months later, the women's infants were offered cerealmi_ed with carrot juice, and their facial e_pressions were observed while theyate it. the offspring of the carrot juice drinking women ate morecarrot-flavored cereal, and from the looks of it, they seemed to enjoy itmore.
a sort of french version of this e_periment was carried out in dijon,france where researchers found that mothers who consumed food and drink flavoredwith licorice-flavored anise during pregnancy showed a preference for anise ontheir first day of life, and again, when they were tested later, on their fourthday of life. babies whose mothers did not eat anise during pregnancy showed areaction that translated roughly as "yuck." what this means is that fetuses areeffectively being taught by their mothers about what is safe and good to eat.fetuses are also being taught about the particular culture that they'll bejoining through one of culture's most powerful e_pressions, which is food.they're being introduced to the characteristic flavors and spices of theirculture's cuisine even before birth.
now it turns out that fetuses are learning even bigger lessons. but beforei get to that, i want to address something that you may be wondering about. thenotion of fetal learning may conjure up for you attempts to enrich the fetus --like playing mozart through headphones placed on a pregnant belly. but actually,the nine-month-long process of molding and shaping that goes on in the womb is alot more visceral and consequential than that. much of what a pregnant womanencounters in her daily life -- the air she breathes, the food and drink sheconsumes, the chemicals she's e_posed to, even the emotions she feels -- areshared in some fashion with her fetus. they make up a mi_ of influences asindividual and idiosyncratic as the woman herself. the fetus incorporates theseofferings into its own body, makes them part of its flesh and blood. and oftenit does something more. it treats these maternal contributions as information,as what i like to call biological postcards from the world outside.
so what a fetus is learning about in utero is not mozart's "magic flute"but answers to questions much more critical to its survival. will it be borninto a world of abundance or scarcity? will it be safe and protected, or will itface constant dangers and threats? will it live a long, fruitful life or ashort, harried one? the pregnant woman's diet and stress level in particularprovide important clues to prevailing conditions like a finger lifted to thewind. the resulting tuning and tweaking of a fetus' brain and other organs arepart of what give us humans our enormous fle_ibility, our ability to thrive in ahuge variety of environments, from the country to the city, from the tundra tothe desert.
to conclude, i want to tell you two stories about how mothers teach theirchildren about the world even before they're born. in the autumn of 1944, thedarkest days of world war ii, german troops blockaded western holland, turningaway all shipments of food. the opening of the nazi's siege was followed by oneof the harshest winters in decades -- so cold the water in the canals frozesolid. soon food became scarce, with many dutch surviving on just 500 calories aday -- a quarter of what they consumed before the war. as weeks of deprivationstretched into months, some resorted to eating tulip bulbs. by the beginning ofmay, the nation's carefully rationed food reserve was completely e_hausted. thespecter of mass starvation loomed. and then on may 5th, 1945, the siege came toa sudden end when holland was liberated by the allies.
the "hunger winter," as it came to be known, killed some 10,000 people andweakened thousands more. but there was another population that was affected --the 40,000 fetuses in utero during the siege. some of the effects ofmalnutrition during pregnancy were immediately apparent in higher rates ofstillbirths, birth defects, low birth weights and infant mortality. but otherswouldn't be discovered for many years. decades after the "hunger winter,"researchers documented that people whose mothers were pregnant during the siegehave more obesity, more diabetes and more heart disease in later life thanindividuals who were gestated under normal conditions. these individuals'prenatal e_perience of starvation seems to have changed their bodies in myriadways. they have higher blood pressure, poorer cholesterol profiles and reducedglucose tolerance -- a precursor of diabetes.
why would undernutrition in the womb result in disease later? onee_planation is that fetuses are making the best of a bad situation. when food isscarce, they divert nutrients towards the really critical organ, the brain, andaway from other organs like the heart and liver. this keeps the fetus alive inthe short-term, but the bill comes due later on in life when those other organs,deprived early on, become more susceptible to disease.
but that may not be all that's going on. it seems that fetuses are takingcues from the intrauterine environment and tailoring their physiologyaccordingly. they're preparing themselves for the kind of world they willencounter on the other side of the womb. the fetus adjusts its metabolism andother physiological processes in anticipation of the environment that awaits it.and the basis of the fetus' prediction is what its mother eats. the meals apregnant woman consumes constitute a kind of story, a fairy tale of abundance ora grim chronicle of deprivation. this story imparts information that the fetususes to organize its body and its systems -- an adaptation to prevailingcircumstances that facilitates its future survival. faced with severely limitedresources, a smaller-sized child with reduced energy requirements will, in fact,have a better chance of living to adulthood.
the real trouble comes when pregnant women are, in a sense, unreliablenarrators, when fetuses are led to e_pect a world of scarcity and are borninstead into a world of plenty. this is what happened to the children of thedutch "hunger winter." and their higher rates of obesity, diabetes and heartdisease are the result. bodies that were built to hang onto every calorie foundthemselves swimming in the superfluous calories of the post-war western diet.the world they had learned about while in utero was not the same as the worldinto which they were born.
here's another story. at 8:46 a.m. on september 11th, __, there were tensof thousands of people in the vicinity of the world trade center in new york --commuters spilling off trains, waitresses setting tables for the morning rush,brokers already working the phones on wall street. 1,700 of these people werepregnant women. when the planes struck and the towers collapsed, many of thesewomen e_perienced the same horrors inflicted on other survivors of the disaster-- the overwhelming chaos and confusion, the rolling clouds of potentially to_icdust and debris, the heart-pounding fear for their lives.
about a year after 9/11, researchers e_amined a group of women who werepregnant when they were e_posed to the world trade center attack. in the babiesof those women who developed post-traumatic stress syndrome, or ptsd, followingtheir ordeal, researchers discovered a biological marker of susceptibility toptsd -- an effect that was most pronounced in infants whose mothers e_periencedthe catastrophe in their third trimester. in other words, the mothers withpost-traumatic stress syndrome had passed on a vulnerability to the condition totheir children while they were still in utero.
now consider this: post-traumatic stress syndrome appears to be a reactionto stress gone very wrong, causing its victims tremendous unnecessary suffering.but there's another way of thinking about ptsd. what looks like pathology to usmay actually be a useful adaptation in some circumstances. in a particularlydangerous environment, the characteristic manifestations of ptsd -- ahyper-awareness of one's surroundings, a quick-trigger response to danger --could save someone's life. the notion that the prenatal transmission of ptsdrisk is adaptive is still speculative, but i find it rather poignant. it wouldmean that, even before birth, mothers are warning their children that it's awild world out there, telling them, "be careful."
let me be clear. fetal origins research is not about blaming women for whathappens during pregnancy. it's about discovering how best to promote the healthand well-being of the ne_t generation. that important effort must include afocus on what fetuses learn during the nine months they spend in the womb.learning is one of life's most essential activities, and it begins much earlierthan we ever imagined.
