unit

A 试题分析：句意：Jane是一个18岁的美国高中生。18-year-old 18岁，做定语，修饰后面的名词，注意有连字符时year不用复数；单词eighteen读音以元音开头，所以前面用冠词an，故选A。

scale是缩放比，不是真正的大小，平时使用可能区别不大，但在物理引擎等方面会出现无法挽回的错误。cube的初始化大小是1米，是所有模型的标准尺度。而unity里面不支持cube及其他模型或对象的大小修改，只能修改其scale，这个问题就涉及到一个比较深层次的原理了。unity的底层是opengl，而opengl对模型的缩放也是只能通过scale，因为从计算机图形学的角度来说，模型的缩放实际上只是乘以一个缩放因子，然后从原点坐标通过坐标轴的变换摆放到适当的位置，而不是直接变换这个模型。变换坐标轴的结果就是只能在结果坐标位置以原始大小按比例缩放，这个缩放所用到的缩放因子就是scale。好吧，讲了那么多可能你也没听懂，涉及的知识比较多。总的来说，你只能通过调整scale来缩放该模型，或者有个更直接的方法，你在做模型的时候把大小调整好再放进来。记住，cube也是模型，跟通过3dmax,maya做出来的模型没有本质区别

Unity是全球应用非常广泛的实时内容开发平台,为游戏、汽车、建筑工程、影视动画等广泛领域的开发者提供强大且易于上手的工具来创作、运营和变现3D、2DVR和AR可视化体验。而一般没有点游戏开发的小伙伴想要自学掌握这个软件，可能就有点困难了！想要自学掌握Unity，还得是要系统的视频课程学习。如果你有想法自学Unity，那么就可以选择的Unity精选视频课程，四个阶段课程，Unity专业讲师带你从基础的软件安装到软件介绍到案例操作~Unity创建项目操作方法：创建新项目启动Unity3D后，会弹出一个项目导航（ProjectWizard）对话框。对该界面详解：项目名称（ProjectName）。项目路径（Location）。工程配置2D或3D。需要加载的系统资源包（AddAssetsPackage）。完成新建项目（CreateProject）成功新建项目后，该项目中会自带一个名为"MainCamera"的相机和一个名为"DirectionalLight"的直线光。新建场景由于每个项目中可能会存在多个不同的场景，所以我们尝试去新建场景。选择Unity3D软件界面上的菜单文件（File）→新建场景命令（NewScene）即可新建场景。创建游戏物体选择界面中的游戏对象（GameObject）→三维物体（3DObject）→立方体（Cube）命令创建一个立方体。可自行尝试创建其他游戏物体哦。最后使用场景控件调整物体的位置，从而完成游戏物体的基本创建。添加游戏物体组件游戏物体组件可以通过Inspector（属性编辑器）显示。组价与组件之间可以附加。为之前创建的立方体（Cube）组件添加刚体组件（Rigidbody）：选中立方体（Cube）。点击组件选项（Component）。点击物理选项（Physics）。点击刚体组件（Rigidbody）。Rigidbody添加完成后，在场景视图中单击立方体（Cube）并将其拖曳到平面上方，然后单击Play按钮进行测试，可以发现立方体（Cube）会做自由落体运动，与地面发生相撞，最后停在地面。保存项目菜单文件（File）→保存场景（SaveScene）或使用快捷键Ctrl+S，然后输入一个文件名保存。以上就是羽兔为各位小伙伴分享到的“Unity怎么创建项目？Unity创建项目操作方法”相关内容了，跟着羽兔学习Unity，慢慢深入，相信一定能够学会！越来越多的开发者开始学习Unity，每个人适合的学习方法都不同，但有一些经验适用于我们每一个人，可以帮助我们少走弯路。想要系统全面的学习掌握到Unity，那么这些Unity视频课程真的不能够错过！点击链接：

unity中cube是透明的是shader设置的问题。根据查询相关资料信息：unity中自带的shader并没有max中的丰富，做模型的时候尽量注意不要用unity中没有的shader，用了那么就只能外部导入shader到unity来保证模型的正常显示了。

But despite all of this momentum, we face some huge challenges. See, you might be thinking to yourself, how can we possibly persuade world leaders to sustain a focus on global issues? Indeed, the powerful American politician Tip O"Neill once said, "All politics is local." That"s what always got politicians elected: to seek, gain and hold onto power through the pursuit of local or at very best national interests. I experienced this for the first time when I was 21 years old. I took a meeting with a then-Australian Foreign Minister who shall remain nameless -- [Alexander Downer] (Laughter) And behind closed doors, I shared with him my passion to end extreme poverty. I said, "Minister -- Australia has this once-in-a-lifetime opportunity to help achieve the Millennium Development Goals. We can do this." And he paused, looked down on me with cold, dismissive eyes, and he said, "Hugh, no one gives a funk about foreign aid." Except he didn"t use the word "funk." He went on. He said we need to look after our own backyard first. This is, I believe, outdated, even dangerous thinking. Or as my late grandfather would say, complete BS. Parochialism offers this false dichotomy because it pits the poor in one country against the poor in another. It pretends we can isolate ourselves and our nations from one another. The whole world is our backyard, and we ignore it at our peril. See, look what happened when we ignored Rwanda, when we ignore Syria, when we ignore climate change. Political leaders ought to give a "funk" because the impact of climate change and extreme poverty comes right to our shore. Now, global citizens -- they understand this. We live in a time that favors the global citizen, in an age where every single voice can be heard. See, do you remember when the Millennium Development Goals were signed back in the year 2000? The most we could do in those days was fire off a letter and wait for the next election. There was no social media. Today, billions of citizens have more tools, more access to information, more capacity to influence than ever before. Both the problems and the tools to solve them are right before us. The world has changed, and those of us who look beyond our borders are on the right side of history. So where are we? So we run this amazing festival, we"ve scored some big policy wins, and citizens are signing up all over the world. But have we achieved our mission? No. We have such a long way to go. But this is the opportunity that I see. The concept of global citizenship, self-evident in its logic but until now impractical in many ways, has coincided with this particular moment in which we are privileged to live. We, as global citizens, now have a unique opportunity to accelerate large-scale positive change around the world. So in the months and years ahead, global citizens will hold world leaders accountable to ensure that the new Global Goals for Sustainable Development are tracked and implemented. Global citizens will partner with the world"s leading NGOs to end diseases like polio and malaria. Global citizens will sign up in every corner of this globe, increasing the frequency, quality and impact of their actions. These dreams are within reach. Imagine an army of millions growing into tens of millions, connected, informed, engaged and unwilling to take no for an answer. Over all these years, I"ve tried to reconnect with Sonny Boy. Sadly, I"ve been unable to. We met long before social media, and his address has now been relocated by the authorities, as often happens with slums. I"d love to sit down with him, wherever he is, and share with him how much the time I spent on Smoky Mountain inspired me. Thanks to him and so many others, I came to understand the importance of being part of a movement of people -- the kids willing to look up from their screens and out to the world, the global citizens. Global citizens who stand together, who ask the question "Why?," who reject the naysayers, and embrace the amazing possibilities of the world we share. I"m a global citizen. Are you? Thank you.

没区别. 美国全称,美利坚合众国（The United States of America）简称美国（U.S.A.）或者（U.S) 在英语中,亚美利加 和美利坚为同一词“America”,只是汉译不同,前者指全美洲,后者指美国.所以在英语中美洲美国都是America 我们中国人喜欢把别人国家名字都弄简称来叫,其实是把你那两个连一起叫便是美国的全称.

Christina sells women"s clothing in a department store . She usually works 6 days a week,  but this week she"s going to take 3 days off.  She"s taking time off   so that she can visit her parents. Her parents live in the mountains, about 3 hours away by train.  They are looking forward to seeing  her. They haven"t seen her for almost a year.  Christina is their only child. Christina isn"t going on the trip by herself.  Her boyfriend is going with her.  She is going to introduce him to her parents.  She and her boyfriend want to get married.  If everything goes well, they plan to get married in 6 months.  After they get married, Christina plans to quit her job .  She wants to spend more time designing clothes.  She wants to  set up her own business. This will take time.  Her boyfriend thinks it"s a good idea.  He"s also thinking about starting his own business. They don"t plan to have children  right away. In fact, they may decide not to have children.  They don"t know yet.  It"s going to be a big decision.  Christina"s parents want her to marry and have children.  They are looking forward to having grandchildren.  They don"t want her to start her own business.  They think it"s more important to have children.  In fact, they would like her to live closer to them.  They want to be close to their grandchildren. So Christina doesn"t plan to tell her parents everything.  For now, she just wants them to meet her boyfriend.  She wants them to be happy that she is going to get married.  She wants them to like him and see her happiness.  She wants her parents to accept her way of life.  Life isn"t the same now as it used to be.  Times are changing. Mechanics , like this one, fix cars.  He"s working in a repair shop . A delivery person delivers things, such as pizzas.  This person works for a restaurant. A pharmacist sells medicines.  Pharmacists, like this woman, work in a pharmacy . Thieves, like this one, steal things.  This thief is stealing a television from a home. A musician , like this one, plays music.  This musician is playing a guitar. These people are wearing masks because of the smog. One cause of smog is automobile exhaust . It"s raining hard so you need an umbrella.  Heavy rain like this can cause flooding and mudslides. When the sky is overcast, we can"t see the sun because of the clouds.  A cloudy sky means that it might rain. We need to wear a coat when it"s cold and windy.  In a very strong wind it"s difficult to use an umbrella. We need to drink water and other liquids when it"s hot outside.  When it"s really hot, most people turn on the air conditioning. Here are some different types of things to read.  Works of fiction include novels, short stories and plays such as Shakespeare .  We read fiction to enjoy stories of imagination and adventure.  People read the news to learn about what"s happening in the world.  We can get the news in newspapers and online.  When we buy something, we often need to read an introduction manual .  Introduction manuals show us how to put together or install things.  Non-fiction works include biographies and books about science and history.  We read non-fiction to learn about different subjects and real people.  We can learn about the latest scientific research in journals and academic papers .  Many online university courses give a list of research papers to read. What"s wrong? I can"t walk.  My left foot hurts. Is it broken? I don"t know if it"s broken, but it sure hurts. There"s one way to find out if it"s broken. How? You need to see a doctor.  The doctor can X-ray your foot. OK, let"s go.  I can"t walk by myself.  Can you help me into a taxi ? Sure, I"ll call a taxi.  I"ll get you to a hospital as soon as possible. Thanks, I sure hope it isn"t broken. We"ll find out soon enough. I don"t feel like cooking tonight.  Let"s go out. Where would you like to go? I feel like eating some great Italian food. How about Al"s Italian?  It"s always good. We went there last week.  Let"s try something new.  You have no imagination.  You always want to go to the same place. Right, I don"t like unpleasant surprises.  I just want things to be simple. OK. Let"s compromise . What does that mean?  What do you mean by compromise? Let"s go 50-50. This time we"ll go some place new and next time we can go to one of your favorites. OK, I"ll compromise and meet you halfway . Good, I"ll look for something new and make reservations. Great, let"s not go too late. I"ll make reservations for 8:00.  Is that OK? Yes, perfect.

你好，这款手机还可以，中端处理器坐着还比较流畅，如果是打游戏就会差一些。

opportunity cost 是个经济学的概念8/12 = 8:12, 你应该把它当作一个比值来看，具体含义是：8个面包的opportunity cost是12个披萨。12/6 = 12:6, 意思是：12个面包的opportunity cost是6个披萨。这个数字越大越好，因为opportunity cost是你所放弃的 （比如，你如果用24小时生产8个面包话，等于放弃了生产12个披萨），所以如果比值是2：1的话说明你每生产2个面包就放弃1个披萨，但如果比值是1：1的话说明你每生产2个面包就放弃2个披萨，比2：1要吃亏

区别：OPPORTUNITYOpportunity is an auspicious state of affairs or a suitable time: Opportunity 是一种有利的状态或合适的时机：“He would . . . trust to time and opportunity for the gratification of his revenge” (Frederick Marryat). “他将…坐等时机来成全他的报复行动” （弗瑞德·莫亚特）.“If you prepare yourself . . . you will be able to grasp opportunity for broader experience when it appears” (Eleanor Roosevelt). “如果你有所准备…一旦机会出现,你就会抓住获得更丰富经历的机会.” （埃利诺·瑞赛尔特）.OCCASION:Occasion suggests the proper time for action: Occasion 暗含作某项行动的适宜时间：“Who would do ill ne"er wants [lacks] occasion” (George Herbert). “干蠢事的人想要〔缺少〕 时机” （乔治·哈伯特）.I seized the occasion to set the record straight.

[谚]疏忽招盗贼。opportunity 拉丁词根port港口，o-在…附近 参考词汇opportunity , occasion , chance , break 这组词的一般含义是“时机”或“机会”。不管在口语中或者在文学作品中，这几个都是常用的词。 opportunity表示某时机符合自己想干某事的意愿、目的、雄心甚至野心。比方：“伺机而动”，这“而动”即去做自己想去完成的事情，此语可译为wait for an opportunity to take action；“借此机会说几句话”，这“说几句话”即说明该时机符合自己想干某事的意愿， 此语可译为to avail oneself of the opportunity to say a few words. Perhaps there is an element of truth in both these pictures,but few of us have had the opportunity to find out.或许这两种想象中都有一定的真实成分，但是我们中很少有人有机会去发现它。A man without an education,many of us believe,is an unfortunate victim of adverse circumstances deprived of one of the greatest twenty-century opportunities.我们许多人都相信，没有受过教育的人是境况不佳的不幸牺牲品，他们被剥夺了20世纪最了不起的机会之一。occasion含有opportunity所能表达的这样一层意思：某时机能激发或唤起某人的某种行为，如：在“必要时”一语中便包含着激发某行为的时刻，此语可译为When occasion demands…；“这不是哭泣的时候。”这句话可译为It"s no occasion for crying。在to have no occasion todo…固定词组中，occasion之所以能够引申为reason或cause的含义，也是与occasion的上述基本词义有关的。 This sort of thing is usual on occasions like this.这类事情在这种场合是常见的。This is not an occasion for laughter.这不是笑的时候。（指不适合于笑，或不是笑的场合。）chance表示幸运或偶然的时机 Perhaps it is the desire for solitude or the chance of making an unexpected discovery that lures men down to the depths of the earth.可能正是寻觅幽静的去处，或者找个猎奇的机会的欲望引诱着人们进入地球的深处。No one discovers a rarity by chance.侥幸发现一件珍品的人是没有的。break作为时机解，一般要求修饰语，如：a good break, a bad break,即“走运”或“坏运气”。这个词的基本意思是：走运不能老走运，倒霉不能老倒霉，总有个break的 That fellow gets all the breaks;he has been working there for only six months and has already been promoted to the position of vice-president.那个家伙真走运，在那里才干了6个月，就已经被提升到总副经理的职位了。He has been assailed by bad breaks all these years.这些年来他接二连三地倒霉。名词 n.1.机会, 时机 He sought opportunities of doing her little service.他寻找机会为她尽一点力。2.适当的时机；有利的场合3.条件4.就业(或晋升、进步等)的良机

Juan Enriquez: What will humans look like in 100 years | TED Talk Here"s a question that matters. Right? Because we"re beginning to get all the tools together to evolve ourselves.  And we can evolve bacteria and we can evolve plants and we can evolve animals,  and we"re now reaching a point where we really have to ask, is it really ethical and do we want to evolve human beings?  And as you"re thinking about that, let me talk about that in the context of prosthetics, prosthetics past, present, future. So this is the iron hand that belonged to one of the German counts.  Loved to fight, lost his arm in one of these battles.  No problem, he just made a suit of armor, put it on, perfect prosthetic.  That"s where the concept of ruling with an iron fist comes from.  And of course these prosthetics have been getting more and more useful, more and more modern. You can hold soft-boiled eggs.  You can have all types of controls, and as you"re thinking about that,  there are wonderful people like Hugh Herr who have been building absolutely extraordinary prosthetics.  So the wonderful Aimee Mullins will go out and say, how tall do I want to be tonight?  Or he will say what type of cliff do I want to climb?  Or does somebody want to run a marathon, or does somebody want to ballroom dance?  And as you adapt these things, the interesting thing about prosthetics is they"ve been coming inside the body.  So these external prosthetics have now become artificial knees. They"ve become artificial hips.  And then they"ve evolved further to become not just nice to have but essential to have. So when you"re talking about a heart pacemaker as a prosthetic,  you"re talking about something that isn"t just, " I"m missing my leg,"  it"s, "if I don"t have this, I can die."  And at that point, a prosthetic becomes a symbiotic relationship with the human body. How have  prosthetics evolved over time? They"ve become more customizable and necessary. Why does Enriquez believe prosthetics have the common ethical issue? They have the ability to radically change the human body. A symbiotic relationship is one in which both sides depend on each other for survival. And four of the smartest people that I"ve ever met -- Ed Boyden, Hugh Herr, Joe Jacobson, Bob Lander -- are working on a Center for Extreme Bionics.  And the interesting thing of what you"re seeing here is these prosthetics now get integrated into the bone. They get integrated into the skin. They get integrated into the muscle.  And one of the other sides of Ed is he"s been thinking about how to connect the brain using light or other mechanisms directly to things like these prosthetics.  And if you can do that, then you can begin changing fundamental aspects of humanity.  So how quickly you react to something depends on the diameter of a nerve.  And of course, if you have nerves that are external or prosthetic, say with light or liquid metal,  then you can increase that diameter and you could even increase it theoretically to the point where,  as long as you could see the muzzle flash, you could step out of the way of a bullet.  Those are the order of magnitude of changes you"re talking about. This is a fourth sort of level of prosthetics. These are Phonak hearing aids,  and the reason why these are so interesting is because they cross the threshold from where prosthetics are something for somebody who is " disabled "  and they become something that somebody who is "normal" might want to actually have,  because what this prosthetic does, which is really interesting, is not only does it help you hear ,  you can focus your hearing, so it can hear the conversation going on over there.  You can have superhearing. You can have hearing in 360 degrees. You can have white noise. You can record, and oh, by the way, they also put a phone into this.  So this functions as your hearing aid and also as your phone.  And at that point, somebody might actually want to have a prosthetic voluntarily. All of these thousands of loosely connected little pieces are coming together ,  and it"s about time we ask the question, how do we want to evolve human beings over the next century or two?  And for that we turn to a great philosopher  who was a very smart man despite being a Yankee fan. And Yogi Berra used to say, of course, that it"s very tough to make predictions, especially about the future.How can prosthetic nerves affect help people to react things? They can be designed to optimize human reaction speed. What role does  Enriquez think prosthetic will have in the future? He isn"t completely sure about their role. When prosthetics become this advanced, somebody might actually want to have one voluntarily.  So instead of making a prediction about the future to begin with, let"s take what"s happening in the present with people like Tony Atala,  who is redesigning 30-some-odd organs.  And maybe the ultimate prosthetic isn"t having something external, titanium. Maybe the ultimate prosthetic is take your own gene code,  remake your own body parts, because that"s a whole lot more effective than any kind of a prosthetic.  But while you"re at it, then you can take the work of Craig Venter and Ham Smith.  And one of the things that we"ve been doing is trying to figure out how to reprogram cells.  And if you can reprogram a cell, then you can change the cells in those organs.  So if you can change the cells in those organs, maybe you make those organs more radiation-resistant. Maybe you make them absorb more oxygen. Maybe you make them more efficient to filter out stuff that you don"t want in your body.  And over the last few weeks, George Church has been in the news a lot  because he"s been talking about taking one of these programmable cells and inserting an entire human genome into that cell.  And once you can insert an entire human genome into a cell, then you begin to ask the question, would you want to enhance any of that genome?  Do you want to enhance a human body?  How would you want to enhance a human body?  Where is it ethical to enhance a human body and where is it not ethical to enhance a human body?  And all of a sudden, what we"re doing is we"ve got this multidimensional chess board  where we can change human genetics by using viruses to attack things like AIDS,  or we can change the gene code through gene therapy to do away with some hereditary diseases, or we can change the environment,  and change the expression of those genes in the epigenome and pass that on to the next generations.  And all of a sudden , it"s not just one little bit, it"s all these stacked little bits  that allow you to take little portions of it until all the portions coming together lead you to something that"s very different.Why is  Enriquez  concerned about genetic prosthetics? They could change the human species radically but unpredictably. What is an example of a cell-based prosthetic? changing an organ to make it resistant radiation And a lot of people are very scared by this stuff.  And it does sound scary, and there are risks to this stuff.  So why in the world would you ever want to do this stuff?  Why would we really want to alter the human body in a fundamental way? The answer lies in part with Lord Rees, astronomer royal of Great Britain.  And one of his favorite sayings is the universe is 100 percent malevolent.  So what does that mean? It means if you take any one of your bodies at random, drop it anywhere in the universe, drop it in space, you die.  Drop it on the Sun, you die. Drop it on the surface of Mercury, you die. Drop it near a supernova, you die.  But fortunately, it"s only about 80 percent effective.  So as a great physicist once said, there"s these little upstream eddies of biology that create order in this rapid torrent of entropy.  So as the universe dissipates energy, there"s these upstream eddies that create biological order.  Now, the problem with eddies is, they tend to disappear. They shift. They move in rivers.  And because of that, when an eddy shifts, when the Earth becomes a snowball, when the Earth becomes very hot, when the Earth gets hit by an asteroid,  when you have supervolcanoes, when you have solar flares,  when you have potentially extinction-level events like the next election -- then all of a sudden, you can have periodic extinctions.  And by the way, that"s happened five times on Earth,  and therefore it is very likely that the human species on Earth is going to go extinct someday.  Not next week, not next month, maybe in November, but maybe 10,000 years after that.  As you"re thinking of the consequence of that,  if you believe that extinctions are common and natural and normal and occur periodically,  it becomes a moral imperative to diversify our species.  And it becomes a moral imperative because  it"s going to be really hard to live on Mars if we don"t fundamentally modify the human body. Right?  You go from one cell, mom and dad coming together to make one cell, in a cascade to 10 trillion cells.  We don"t know, if you change the gravity substantially, if the same thing will happen to create your body.  We do know that if you expose our bodies as they currently are to a lot of radiation, we will die.  So as you"re thinking of that, you have to really redesign things just to get to Mars.  Forget about the moons of Neptune or Jupiter. What does Enriquez mean when he says the universe is 100 percent malevolent? Humans can"t survive anywhere other than Earth. According to Enriquez  what is a moral imperative for the human race?  using prosthetics to enhance the human species If human beings want to live on Mars they will need to modify their bodies to survive. And to borrow from Nikolai Kardashev, let"s think about life in a series of scales.  So Life One civilization is a civilization that begins to alter his or her looks.  And we"ve been doing that for thousands of years.  You"ve got tummy tucks and you"ve got this and you"ve got that.  You alter your looks and I"m told that not all of those alterations take place for medical reasons. Seems odd. A Life Two civilization is a different civilization.  A Life Two civilization alters fundamental aspects of the body.  So you put human growth hormone in, the person grows taller, or you put x in and the person gets fatter or loses metabolism or does a whole series of things,  but you"re altering the functions in a fundamental way.  To become an intrasolar civilization, we"re going to have to create a Life Three civilization,  and that looks very different from what we"ve got here.  Maybe you splice in Deinococcus radiodurans so that the cells can resplice after a lot of exposure to radiation.  Maybe you breathe by having oxygen flow through your blood instead of through your lungs.  But you"re talking about really radical redesigns  and one of the interesting things that"s happened in the last decade is we"ve discovered a whole lot of planets out there.  And some of them may be Earth-like.  The problem is, if we ever want to get to these planets, the fastest human objects  -- Juno and Voyager and the rest of this stuff -- take tens of thousands of years to get from here to the nearest solar system.  So if you want to start exploring beaches somewhere else,  or you want to see two-sun sunsets, then you"re talking about something that is very different,  because you have to change the timescale and the body of humans in ways which may be absolutely unrecognizable.  And that"s a Life Four civilization.How does  Enriquez describe a life one civilization? People begin to modify their appearance. What the humans need to do if they want to reach distance planets and solar systems? change how human bodies age over long periods of time In order to develop an intrasolar civilization, humans would have to modify the body to allow long-distance space travel. In a life two civilization, people can use growth hormones to change fundamental aspects of the body . Now, we can"t even begin to imagine what that might look like, but we"re beginning to get glimpses of instruments that might take us even that far.  And let me give you two examples. So this is the wonderful Floyd Romesberg,  and one of the things that Floyd"s been doing is he"s been playing with the basic chemistry of life. 

Casey Gerald: The gospel of doubt | TED Talk There we were, souls and bodies packed into a Texas church on the last night of our lives. Packed into a room just like this, but with creaky wooden pews draped in worn-down red fabric, with an organ to my left and a choir at my back and a baptism pool built into the wall behind them. A room like this, nonetheless. With the same great feelings of suspense, the same deep hopes for salvation, the same sweat in the palms and the same people in the back not paying attention. This was December 31,1999, the night of the Second Coming of Christ, and the end of the world as I knew it. I had turned 12 that year and had reached the age of accountability. And once I stopped complaining about how unfair it was that Jesus would return as soon as I had to be accountable for all that I had done, I figured I had better get my house in order very quickly. So I went to church as often as I could. I listened for silence as anxiously as one might listen for noise, trying to be sure that the Lord hadn"t pulled a fast one on me and decided to come back early. And just in case he did, I built a backup plan, by reading the "Left Behind" books that were all the rage at the time. And I found in their pages that if I was not taken in the rapture at midnight, I had another shot. All I had to do was avoid taking the mark of the beast, fight off demons, plagues and the Antichrist himself. It would be hard --but I knew I could do it.Why was December 31,1999 significant to Gerald? He thought Jesus would return on this date. Why does Gerald use humor in his presentation ? to engage the audience How does Gerald describe the life behind the books? They were very popular at the time. By reaching the age of accountability, Gerald had to start taking  the responsibility for his behavior. When he reach the age of accountability, he had to take the responsibility for all he had done. But planning time was over now. It was 11:50 pm. We had 10 minutes left, and my pastor called us out of the pews and down to the altar because he wanted to be praying when midnight struck. So every faction of the congregation took its place. The choir stayed in the choir stand, the deacons and their wives -- or the Baptist Bourgeoisie as I like to call them --took the first position in front of the altar. You see, in America, even the Second Coming of Christ has a VIP section. And right behind the Baptist Bourgeoisie were the elderly -- these men and women whose young backs had been bent under hot suns in the cotton fields of East Texas, and whose skin seemed to be burnt a creaseless noble brown, just like the clay of East Texas, and whose hopes and dreams for what life might become outside of East Texas had sometimes been bent and broken even further than their backs. Yes, these men and women were the stars of the show for me. They had waited their whole lives for this moment, just as their medieval predecessors had longed for the end of the world, and just as my grandmother waited for the Oprah Winfrey Show to come on Channel 8 every day at 4 o"clock. And as she made her way to the altar, I snuck right in behind her, because I knew for sure that my grandmother was going to heaven. And I thought that if I held on to her hand during this prayer, I might go right on with her. So I held on and I closed my eyes to listen, to wait. And the prayers got louder. And the shouts of response to the call of the prayer went up higher even still. And the organ rolled on in to add the dirge. And the heat came on to add to the sweat. And my hand gripped firmer, so I wouldn"t be the one left in the field. My eyes clenched tighter so I wouldn"t see the wheat being separated from the chaff. And then a voice rang out above us: "Amen."What does Gerald suggest by in America even the Second Coming of Christ has a VIP section? American society is obsessed with class and social status. Gerald believed that if he held onto his grandmother"s hand as she prayed he would go to heaven. It was over. I looked at the clock. It was after midnight. I looked at the elder believers whose savior had not come, who were too proud to show any signs of disappointment, who had believed too much and for too long to start doubting now. But I was upset on their behalf . They had been duped, hoodwinked, bamboozled, and I had gone right along with them. I had prayed their prayers, I had yielded not to temptation as best I could. I had dipped my head not once, but twice in that snot-inducing baptism pool. I had believed. Now what? I got home just in time to turn on the television and watch Peter Jennings announce the new millennium as it rolled in around the world. It struck me that it would have been strange anyway, for Jesus to come back again and again based on the different time zones. And this made me feel even more ridiculous -- hurt, really. But there on that night, I did not stop believing. I just believed a new thing: that it was possible not to believe. It was possible the answers I had were wrong, that the questions themselves were wrong. And now, where there was once a mountain of certitude, there was, running right down to its foundation, a spring of doubt, a spring that promised rivers. I can trace the whole drama of my life back to that night in that church when my savior did not come for me; when the thing I believed most certainly turned out to be, if not a lie, then not quite the truth. And even though most of you prepared for Y2K in a very different way, I"m convinced that you are here because some part of you has done the same thing that I have done since the dawn of this new century, since my mother left and my father stayed away and my Lord refused to come. And I held out my hand, reaching for something to believe in.Why did Gerald tell his church story at the beginning of the talk? to show the first time his beliefs changed What would have been strange if Jesus had actually come back? He would have had to come back several times. I looked at the elder believers who were too proud to show any signs of disappointment. I held on when I arrived at Yale at 18, with the faith that my journey from Oak Cliff, Texas was a chance to leave behind all the challenges I had known, the broken dreams and broken bodies I had seen. But when I found myself back home one winter break, with my face planted in the floor, my hands tied behind my back and a burglar"s gun pressed to my head, I knew that even the best education couldn"t save me. I held on when I showed up at Lehman Brothers as an intern in 2008. So hopeful that I called home to inform my family that we"d never be poor again. But as I witnessed this temple of finance come crashing down before my eyes, I knew that even the best job couldn"t save me. I held on when I showed up in Washington DC as a young staffer, who had heard a voice call out from Illinois, saying, "It"s been a long time coming, but in this election, change has come to America." But as the Congress ground to a halt and the country ripped at the seams and hope and change began to feel like a cruel joke, I knew that even the political second coming could not save me. I had knelt faithfully at the altar of the American Dream, praying to the gods of my time of success, and money, and power. But over and over again, midnight struck, and I opened my eyes to see that all of these gods were dead. And from that graveyard, I began the search once more, not because I was brave, but because I knew that I would either believe or I would die.What do Gerald to experience in college at his job and working for the government reinforce? the prevalence of doubt in his life What does Gerald mean by these golds were dead? He couldn"t find meaning in education, success, or power. By going to college, he thought he would be able to escape from his problems. So I took a pilgrimage to yet another mecca, Harvard Business School -- this time, knowing that I could not simply accept the salvation that it claimed to offer. No, I knew there"d be more work to do. The work began in the dark corner of a crowded party, in the late night of an early, miserable Cambridge winter, when three friends and I asked a question that young folks searching for something real have asked for a very long time: "What if we took a road trip?" We didn"t know where"d we go or how we"d get there, but we knew we had to do it. Because all our lives we yearned, as Jack Kerouac wrote, to "sneak out into the night and disappear somewhere," and go find out what everybody was doing all over the country. So even though there were other voices who said that the risk was too great and the proof too thin, we went on anyhow. We went on 8,000 miles across America in the summer of 2013, through the cow pastures of Montana, through the desolation of Detroit, through the swamps of New Orleans, where we found and worked with men and women who were building small businesses that made purpose their bottom line. And having been trained at the West Point of capitalism, this struck us as a revolutionary idea. And this idea spread, growing into a nonprofit called MBAs Across America, a movement that landed me here on this stage today. It spread because we found a great hunger in our generation for purpose, for meaning. It spread because we found countless entrepreneurs in the nooks and crannies of America who were creating jobs and changing lives and who needed a little help. But if I"m being honest, it also spread because I fought to spread it. There was no length to which I would not go to preach this gospel, to get more people to believe that we could bind the wounds of a broken country, one social business at a time. But it was this journey of evangelism that led me to the rather different gospel that I"ve come to share with you today.Why did the organization spread? It focused on purpose. As a result of Gerald"s road trip he found an idea he could believe in. It began one evening almost a year ago at the Museum of Natural History in New York City, at a gala for alumni of Harvard Business School. Under a full-size replica of a whale, I sat with the titans of our time as they celebrated their peers and their good deeds. There was pride in a room where net worth and assets under management surpassed half a trillion dollars. We looked over all that we had made, and it was good. But it just so happened, two days later, I had to travel up the road to Harlem, where I found myself sitting in an urban farm that had once been a vacant lot, listening to a man named Tony tell me of the kids that showed up there every day. All of them lived below the poverty line. Many of them carried all of their belongings in a backpack to avoid losing them in a homeless shelter. Some of them came to Tony"s program, called Harlem Grown, to get the only meal they had each day. Tony told me that he started Harlem Grown with money from his pension , after 20 years as a cab driver. He told me that he didn"t give himself a salary , because, despite success, the program struggled for resources. He told me that he would take any help that he could get. And I was there as that help. But as I left Tony, I felt the sting and salt of tears welling up in my eyes. I felt the weight of revelation that I could sit in one room on one night, where a few hundred people had half a trillion dollars, and another room, two days later, just 50 blocks up the road, where a man was going without a salary to get a child her only meal of the day.What contrast does Gerald draw between Harvard Business and Tony? Tony has sacrificed more despite having less than the alumni. And it wasn"t the glaring inequality that made me want to cry, it wasn"t the thought of hungry, homeless kids, it wasn"t rage toward the one percent or pity toward the 99. No, I was disturbed because I had finally realized that I was the dialysis for a country that needed a kidney transplant. I realized that my story stood in for all those who were expected to pick themselves up by their bootstraps, even if they didn"t have any boots;  that my organization stood in for all the structural, systemic help that never went to Harlem or Appalachia or the Lower 9th Ward;  that my voice stood in for all those voices that seemed too unlearned, too unwashed, too unaccommodated. And the shame of that, that shame washed over me like the shame of sitting

And the shame of that, that shame washed over me like the shame of sitting in front of the television, watching Peter Jennings announce the new millennium again and again and again. I had been duped, hoodwinked, bamboozled.  But this time, the false savior was me. You see, I"ve come a long way from that altar on the night I thought the world would end,  from a world where people spoke in tongues and saw suffering as a necessary act of God and took a text to be infallible truth. Yes, I"ve come so far that I"m right back where I started. Because it simply is not true to say that we live in an age of disbelief -- no, we believe today just as much as any time that came before. Some of us may believe in the prophecy of Brené Brown or Tony Robbins. We may believe in the bible of The New Yorker or the Harvard Business Review. We may believe most deeply when we worship right here at the church of TED, but we desperately want to believe, we need to believe. We speak in the tongues of charismatic leaders that promise to solve all our problems. We  see  suffering  as  a necessary  act  of the capitalism that is our god, we  take  the text of technological progress to be infallible truth. And we  hardly  realize the human price we pay  when  we fail to question one brick, because we fear it  might  shake our whole foundation. But if you are disturbed by the unconscionable things that we have come to accept, then it must be questioning time. So I have not a gospel of disruption or innovation or a triple bottom line. I do not have a gospel of faith to share with you today, in fact. I have and I offer a gospel of doubt. The gospel of doubt does not ask that you stop believing, it asks that you believe a new
