The earth was formed about 4.6 billion years ago. The first live appeared about a billion years later. The first plants didn"t appear until around 2 billion years ago. Until about 580 million years ago, life forms were small and microscopic 微小的 . Since that time, life has evolved into many different types, or species. However scientists estimate that more than 99% of them are now distinct. There have been several extinction events in the history of the Earth. In an extinction event, many life forms or species of life die out. The causes of massive extinction events are unsolved mysteries 未解之谜 . These events are not predictable and can happen at any time. Scientists think that some of them were started by asteroid 小行星 impacts 撞击 or volcanic corruptions 火山爆发 . Events like these can change the global conditions that life depend on. One major extinction event happened about 66 million years ago. That event may have been started by a large asteroid that hit the Earth. As a result the dinosaurs 恐龙 and about half of all species on the planet died out. When the asteroid hit the Earth it started a chain of events. A chain of events is a series of events linked together like a chain. This particular chain of events happened over a period of months and years. When the asteroid hit the Earth, it caused a huge cloud of dust to enter the atmosphere. The cloud of dust blocked the sun and darkened the Earth for many months. Without enough sunlight, plants and plant-eating animals quickly died. With the deaths of so many plants and animals, the food chain collapsed. This lead to the death of many more species. Massive extinction events have played an important part in the evolution of life. In fact, some extinction events have helped to accelerate the evolution. For example some mammals lives through the age of dinosaurs but they couldn"t compete. When the dinosaurs were removed the mammals were able to compete more successfully. Once they could compete mammals evolved to a higher state. Without extinction events perhaps we wouldn"t be here today. Scientists estimate that there have been at least 5 massive extinction in the last 540 million years. They also believed that we have entered a new extinction event. Species are becoming extinct at a much faster rate than before. Instead of asteroid or volcanic corruptions, the current event is the result of human activities. Human Activities for example have lead to global warming. Global warming is the result of an increase in carbon gases in our atmosphere. These gases trap heat from the sun, so the Earth is getting warmer. As a result, sea levels are rising and weather patterns are changing. In addition we humans are destroying the habitats 栖息地 of many plants and animals. Cutting down forests and polluting rivers destroys the habitats of many forms of life. There is no longer any doubt that this is happening. Species of life are disappearing at an increasing rate. Global temperatures are rising and wether patterns are changing. Scientists are warning us that fast action is necessary to save our future. If we don"t act, we may go the way of the dinosaurs. Fire provided light so that people could work and socialize for longer hours. Alcatraz is a small island in San Francisco bay, 1.5 miles from San Francisco.

这两年股市操作难度很大，很多券商和三方平台都推出了Level 2 十档行情的工具来辅助大家炒股，像有些券商会给20w以上的客户免费送Level 2 十档行情。像同花顺这种平台，Level 2 行情一年的费用就是298元，所以如果可以免费拿到这个辅助工具，还是很划算的！但是你真的知道Level 2十档行情是什么，怎么用吗？最详细总结让你一篇搞懂 Level 2 ！【认知篇】一、Level 2 十档行情是什么？沪深Level 2 是沪深交易所推出的实时行情信息服务，涵盖沪深交易所上市交易的所有证券产品。相比已有的传统行情（即Level 1 行情），Level 2 提供更加准确、快速、有效的实时交易数据。港股Level 2 是港交所推出的针对港股的实时行情信息服务，涵盖了在港交所上市交易的所有股票。提供港股十档挂单情况。港股Level 2 十档行情：二、Level 2 十档行情怎么用？1、怎么看十档行情？打开任意个股，在盘口即可查看买一到买十、卖一到卖十委托挂单情况。Level 1 行情只能看五档报价，但五档报价内看似风平浪静，但主力很可能在五档报价之外挂单悄悄布局。使用Level 2 行情便可看到买卖十档报价，看得更多看得更远，主力动向尽收眼底。2、如何看逐笔成交？点击“更多成交”进入逐笔成交明细页，精确查看每笔成交，跟踪资金动向。由于Level 1 成交数据是3秒刷新一次，期间的所有成交数据是汇总显示的，而Level 2 的成交数据是主动推送的，毫秒级的变动频率，因此可看清每一笔成交情况，与Level 1 行情的成交情况差异巨大！Level 2 行情将真实的每笔成交和成交量以明细数据呈现给用户。用户可通过查看明细成交数据，判断出委托是属于大单、中单、小单并以此推断出是机构、大户、散户等所为，查明主力之意图。3、如何看最佳买卖价位委托明细？即买一卖一位置的挂挡情况挂单情况可让用户及时了解到买卖队列，以便获悉完整的盘口情况。用户可通过观察挂单情况来判断该档位是否有主力资金介入，可判断盘口中主力动态，进而把握投资机会。三、超级Level 2 （仅提供深圳市场的A股）在深圳股票档位下，有超级Level 2 入口，点击进入！超级Level 2 功能点：1、总买总卖：统计所有千档的总买总卖数量2、全息队列：可查看买卖千档下每个档位的前50笔委托队列情况3、逐笔委托：展示真实的挂单明细，散户主力动作一览无余四、如何获取Level 2 十档行情？方式一：个股详情页进入购买用户可在交易时段，进入沪深或港股通个股行情详情界面，点击“切换十档急速行情”，进入Level 2 十档行情购买页面。根据界面提示选择套餐，完成支付后，可获取Level 2 十档行情服务。方式二：通过“我的”栏目购买用户可通过APP“我的”栏目中，点击“我的Level 2”。在进入的界面，根据提示选择套餐，完成支付后，可获取Level 2 十档行情服务。【实战篇】一、十档行情看得更深目前我们使用的普通免费行情软件，在盘口委盘栏内我们可以看到买一到买五，以及卖一到卖五，买卖双向共10个价位的挂单情况，也就是我们常说的“五档行情”。但在Level 2 行情软件中，我们的视野被扩展到“十档行情”（即买一到买十、卖一到卖十），无疑比免费软件看得更深。十档行情的盘口技巧：1、在十档行情中，卖单明显比买单多，但卖一的位置上没有出现大卖单，同时股价稳步上涨，这种现象很可能是主力在进行打压式吸筹。2、在买一到买十的位置上，某个价位上出现大买单，一般不是出现在买一位置。然后那个价位的大买单被一个大卖单成交掉，又在一个更低的价位出现大买单。这种现象出现的次数越多我们越需要提高警惕，提防主力资金故意制造大资金吸筹的假象，真实目的却是为了出货。3、在卖一到卖十其中一个价位上挂着一个很大的卖单，多方多次攻击这个价位都不能冲破，意味着主力资金当天不想股价突破这个价位，这个价位很可能成为全天股价运行的阻力位。4、在十档行情中，买盘中某个价位上出现特大买单，同时卖单的某个价位上也有特大卖盘，股价在两个价位之间震荡，意味着主力资金想把价格控制在这个幅度之内。而大买单的价位很可能成为该股当天的支撑位，而大卖单的价位很可能成为该股当天的阻力位。5、如果一只股票盘中震荡盘跌，K线形态上也是破位下行，当天接近尾盘的时候买单增加，股价随即反弹几个价位。而我们观察十档行情，发现买一到买五的挂单明显比卖一到卖五的卖单多。此时，我们需要提防很可能是主力在制造有大资金接盘的假象，其实是为了继续出货。6、如果一只股票盘中震荡向上，日均线呈现多头排列并向上发散。当日接近尾盘时，卖单却增加了，卖一到卖五的挂单明显多于买一到买五，造成股价上攻压力重重的感觉。但是细看十档行情，发现卖六到卖十并未出现大单委托，所谓抛压一戳击破。这类现象很可能是主力压盘的表现，后市行情继续看好的概率很高。二、买卖队列看得更透在传统行情软件中我们只能看到买一、卖一上的委托数量，但无从得知这些委托数量是如何形成的。而在Level 2 行情软件中提供买一、卖一挂单的前50笔委托明细，根据委托单的情况能有助于我们判断是主力机构挂单，还是散户所为。用好买卖队列，判断主力是都已经出手！在看盘过程中关注买一和卖一的买卖队列，软件会把前50笔挂单按顺序列出来，小单子可以忽略不计，如果出现大单就值得我们密切关注哦！举个例子：如果有支股票在“十档行情”里“买一”的位置上有5000手的买单，而“买卖队列”中显示，这5000手的买单是由2000手和3000手两笔买入委托构成的，这就表明很可能是主力资金正在大单买入。反之，如果5000手的买单是由几十笔几十手，甚至几手的小单子组成，那么基本上就是散户挂单了。三、成交明细看得更准在Level 2 行情之前，沪深交易所提供的都是行情快照。大家看到的分时成交明细其实是两次快照期间累计的成交量和最后一笔的价格。而Level 2 的逐笔成交则是真实的每笔成交价和成交量的明细数据，极大地提高了行情的透明度。简单说，我们在免费行情中看到的分时成交明细，并不是真正意义上的及时逐步成交明细，是每3秒刷新一次的行情快照。统计方式是机械的把3秒内的成交量相加，在这3秒内以最后的一笔来定是内盘还是外盘，这显然会对交易者产生一定的误导。举个例子：如果有只股票在两次快照期间，先有200手的买单以卖一价成交，然后又有10手的卖单以买一价成交。免费行情显示：外盘数量没有增加，内盘数量增加210手。Level 2 显示：外盘数量增加200手，内盘数量增加10手。再来个例子：如果有只股票在两次快照期间，先有一笔1000手的大卖单以买一价成交，之后又有一笔1手的买单以卖一价成交。免费行情显示：外盘数量增加1001手。（让投资者误以为有大单吸纳！）Level 2 显示：内盘数量增加1000手，外盘数量增加1手。这就是为什么在免费行情中，有时候明明显示有一笔大买单成交，但是买一的数量瞬间变小了，而卖一的数量没有什么变化，这种情况可能是买一撤单了，但也可能是真实成交了。在Level 2 行情中我们会看到真实的逐笔成交数据，下面我们就来看看要怎么用好这些更精确的数据，提升我们研判的准确性。「小贴士」通过在逐笔成交中：数量手一栏，显示绿色，表示以买入价成交，计入内盘数量手一栏，显示红色，表示以卖出价成交，计入外盘外盘 ＞ 内盘：表示买方力量较强内盘 ＞ 外盘：表示卖方力量较强操作策略：1、股价较长时间的数浪下跌，处于低价位处：成交量极度萎缩后，开始温和放量；当日外盘数量增加，大于内盘。后市股价上涨的概率更大。2、股价较长时间的数浪上涨，处于较高价位；成交量急剧放大后，显示不能再继续放巨量，后量不能超前量或出现量价背离；当日内盘数量增加，大于外盘。后市股价下跌的概率更大。最后说一点：Level 2 十档行情这个辅助工具在市面上褒贬不一，有人觉得用了它胜率会变高，有人觉得完全没有用。我个人的看法是，这个工具本身是没有任何问题的，关键是在于你会不会用，怎么用。如果你能完全理解我写的Level 2 十档行情的相关介绍，那我觉得你是适合使用这个辅助工具的，因为你对于股市，对于实操是有一定理解的，那经过简单的学习和简单的操作，相信这个工具对于你炒股还是会有一定帮助的！毕竟有些券商这个工具是免费的！不要白不要呗~

你从哪看来的？原句子是什么？英语忌讳断章取义，你最好给出具体句子，单从字面意思看，是多层次平面。

I want to introduce you to an amazing woman. Her name is Davinia. Davinia was born in Jamaica, emigrated to the US at the age of 18, and now lives just outside of Washington, DC. She"s not a high-powered political staffer, nor a lobbyist. She"d probably tell you she"s quite unremarkable, but she"s having the most remarkable impact. What"s incredible about Davinia is that she"s willing to spend time every single week focused on people who are not her: people not her in her neighborhood, her state, nor even in her country -- people she"d likely never meet. Davinia"s impact started a few years ago when she reached out to all of her friends on Facebook, and asked them to donate their pennies so she could fund girls" education. She wasn"t expecting a huge response, but 700,000 pennies later, she"s now sent over 120 girls to school. When we spoke last week, she told me she"s become a little infamous at the local bank every time she rocks up with a shopping cart full of pennies. Now -- Davinia is not alone. Far from it. She"s part of a growing movement. And there"s a name for people like Davinia: global citizens. A global citizen is someone who self-identifies first and foremost not as a member of a state, a tribe or a nation, but as a member of the human race, and someone who is prepared to act on that belief, to tackle our world"s greatest challenges. Our work is focused on finding, supporting and activating global citizens. They exist in every country and among every demographic. I want to make the case to you today that the world"s future depends on global citizens. I"m convinced that if we had more global citizens active in our world, then every single one of the major challenges we face -- from poverty, climate change, gender inequality -- these issues become solvable. They are ultimately global issues, and they can ultimately only be solved by global citizens demanding global solutions from their leaders.Now, some people"s immediate reaction to this idea is that either it"s a bit utopian or even threatening. So I"d like to share with you a little of my story today, how I ended up here, how it connects with Davinia and, hopefully, with you. Growing up in Melbourne, Australia, I was one of those seriously irritating little kids that never, ever stopped asking, "Why?" You might have been one yourself. I used to ask my mum the most annoying questions. I"d ask her questions like, "Mum, why I can"t I dress up and play with puppets all day?" "Why do you want fries with that?" "What is a shrimp, and why do we have to keep throwing them on the barbie?" (Laughter) "And mum -- this haircut. Why?" (Laughter) The worst haircut, I think. Still terrible. As a "why" kid, I thought I could change the world, and it was impossible to convince me otherwise. And when I was 12 and in my first year of high school, I started raising money for communities in the developing world. We were a really enthusiastic group of kids, and we raised more money than any other school in Australia. And so I was awarded the chance to go to the Philippines to learn more. It was 1998. We were taken into a slum in the outskirts of Manila. It was there I became friends with Sonny Boy, who lived on what was literally a pile of steaming garbage. "Smoky Mountain" was what they called it. But don"t let the romance of that name fool you, because it was nothing more than a rancid landfill that kids like Sonny Boy spent hours rummaging through every single day to find something, anything of value. That night with Sonny Boy and his family changed my life forever, because when it came time to go to sleep, we simply laid down on this concrete slab the size of half my bedroom with myself, Sonny Boy, and the rest of his family, seven of us in this long line, with the smell of rubbish all around us and cockroaches crawling all around. And I didn"t sleep a wink, but I lay awake thinking to myself, "Why should anyone have to live like this  when  I have so  much ? Why should Sonny Boy"s ability to live out his dreams be  determined  by where he"s born, or  what  Warren Buffett called "the ovarian lottery?"" I just didn"t get it, and I needed to understand why. Now, I only later came to understand that the poverty I"d seen in the Philippines was the result of decisions made or not made, man-made, by a succession of colonial powers and corrupt governments who had anything but the interests of Sonny Boy at heart. Sure, they didn"t create Smoky Mountain, but they may as well have. And if we"re to try to help kids like Sonny Boy, it wouldn"t work just to try to send him a few dollars or to try to clean up the garbage dump on which he lived, because the core of the problem lay elsewhere. And as I worked on community development projects over the coming years trying to help build schools, train teachers, and tackle HIV and AIDS, I came to see that community development should be driven by communities themselves, and that although charity is necessary, it"s not sufficient. We need to confront these challenges on a global scale and in a systemic way. And the best thing I could do is try to mobilize a large group of citizens back home to insist that our leaders engage in that systemic change. That"s why, a few years later, I joined with a group of college friends in bringing the Make Poverty History campaign to Australia. We had this dream of staging this small concert around the time of the G20 with local Aussie artists, and it suddenly exploded one day when we got a phone call from Bono, the Edge and Pearl Jam, who all agreed to headline our concert. I got a little bit excited that day, as you can see. (Laughter) But to our amazement, the Australian government heard our collective voices, and they agreed to double investment into global health and development -- an additional 6.2 billion dollars. It felt like -- (Applause) It felt like this incredible validation. By rallying citizens together, we helped persuade our government to do the unthinkable, and act to fix a problem miles outside of our borders. But here"s the thing: it didn"t last. See, there was a change in government, and six years later, all that new money disappeared. What did we learn? We learned that one-off spikes are not enough. We needed a  sustainable  movement, not  one that is  susceptible  to the  fluctuating  moods of a politician or the hint of an economic  downturn . And it needed to happen everywhere; otherwise, every individual government would have this built-in excuse mechanism that they couldn"t possibly carry the burden of global action alone. And so this is what we embarked upon. And as we embarked upon this challenge, we asked ourselves, how do we gain enough pressure and build a broad enough army to win these fights for the long term? We could only think of one way. We needed to somehow turn that short-term excitement of people involved with the Make Poverty History campaign into long-term passion. It had to be part of their identity. So in 2012, we cofounded an organization that had exactly that as its goal. And there was only one name for it: Global Citizen. But this is not about any one organization. This is about citizens taking action. And research data tells us that of the total population who even care about global issues, only 18 percent have done anything about it. It"s not that people don"t want to act. It"s often that they don"t know how to take action, or that they believe that their actions will have no effect. So we had to somehow recruit and activate millions of citizens in dozens of countries to put pressure on their leaders to behave altruistically. And as we did so, we discovered something really thrilling, that when you make global citizenship your mission, you suddenly find yourself with some extraordinary allies. See, extreme poverty isn"t the only issue that"s fundamentally global. So, too, is climate change, human rights, gender equality, even conflict. We found ourselves shoulder to shoulder with people who are passionate about targeting all these interrelated issues. But how did we actually go about recruiting and engaging those global citizens? Well, we used the universal language: music. We launched the Global Citizen Festival in the heart of New York City in Central Park, and we persuaded some of the world"s biggest artists to participate. We made sure that these festivals coincided with the UN General Assembly meeting, so that leaders who need to hear our voices couldn"t possible ignore them. But there was a twist: you couldn"t buy a ticket. You had to earn it. You had to take action on behalf of a global cause, and only once you"d done that could you earn enough points to qualify. Activism is the currency. I had no interest in citizenship purely as some sort of feel-good thing. For me, citizenship means you have to act, and that"s what we required. And amazingly, it worked. Last year, more than 155,000 citizens in the New York area alone earned enough points to qualify. Globally, we"ve now signed up citizens in over 150 countries around the world. And last year, we signed up more than 100,000 new members each and every week of the whole year. See, we don"t need to create global citizens from nothing. We"re already everywhere. We just need to be organized and motivated to start acting. And this is where I believe we can learn a lot from Davinia, who started taking action as a global citizen back in 2012. Here"s what she did. It wasn"t rocket science. She started writing letters, emailing politicians" offices. She volunteered her time in her local community. That"s when she got active on social media and started to collect pennies -- a lot of pennies. Now, maybe that doesn"t sound like a lot to you. How will that achieve anything? Well, it achieved a lot because she wasn"t alone. Her actions, alongside 142,000 other global citizens", led the US government to double their investment into Global Partnership for Education. And here"s Dr. Raj Shah, the head of USAID, making that announcement. See, when thousands of global citizens find inspiration from each other, it"s amazing to see their collective power. Global citizens like Davinia helped persuade the World Bank to boost their investment into water and sanitation . Here"s the Bank"s president Jim Kim announcing 15 billion dollars onstage at Global Citizen, and Prime Minister Modi of India affirmed his commitment to put a toilet in every household and school across India by 2019. Global citizens encouraged by the late-night host Stephen Colbert launched a Twitter invasion on Norway. Erna Solberg, the country"s Prime Minister, got the message, committing to double investment into girls" education. Global citizens together with Rotarians called on the Canadian, UK, and Australian governments to boost their investment into polio eradication. They got together and committed 665 million dollars. 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.

One of the most interesting books of the 20th century was the novel, Catch 22《第二十二条军规》. In the novel, the term "a catch 22 situation" was introduced. The term has nothing to do with catching anything. It has a much deeper meaning, and it describes a kind of logical conundrum [kəˈnʌndrəm 难题] that"s worth exploring . First, it"s important to put the phrase into context [置于上下文中]. In the novel, a group of American bomber pilots is on an island in the Mediterranean. They face death almost every day when they fly their bombing missions. Many have already lost their lives. The remaining pilots know that it is only a matter of the time before they will be the next victims. One of the characters in the novel is a doctor. It is his job to see that the pilots are fit to fly. In particular, there is rule that says he has to ground [禁止] anyone who is crazy. To ground them means to remove them from active duty [战时服役] so that they don"t fly. Some of the men believed in the principles they were fighting for. They were willing to give their lives for their country. But to others, this was crazy. They thought the whole thing was insane . One of them, Yossarian, wanted out. He was friends with the doctor, and he wanted the doctor to ground him. When Yossarian asked the doctor to ground him, the doctor replied: “you"re wasting your time, you"re not crazy”. Yossarian told him to ask one of the other pilots, Clevinger, to tell him how crazy he was. “There is no point [没有意义]. He"s crazy.” The doctor replied.” Crazy people can"t decide whether you are crazy or not.” “Clevinger isn"t crazy! he"s one of the sanest pilots here.” “So he"s obviously out of his head,” said the Doc. “He"s got to be insane to keep on flying combat missions after all the close calls  [幸免于难] he"s had.”“well, if he"s crazy, why don"t you ground him?” “I can"t unless he asks to be grounded. That"s part of the rule.” “So all he has to do is ask?” “no, then I can"t ground him.” “So there is a catch,” said Yossarian, trying to get things straight. “Sure, there"s a catch,” said the Doc, with a slight smile. “Catch 22. If he asks, then he can"t be crazy. Only those who are crazy are grounded.” “That"s some catch,” observed [评论] Yossarian. “It"s the best there is, ” the Doc replied. To believe in principles means...to have a set of basic truths that guide one"s actions.

“如果你能证明自己发疯，那就说明你没疯”。源出美国作家约瑟夫·赫勒（JosephHeller）根据自己在 第二次世界大战 中的亲身经历创作的黑色幽默小说 《第二十二条军规》 （1961）。这部小说太有影响了，以至于在当代美语中，Catch-22已作为一个独立的单词，使用频率极高，用来形容任何自相矛盾、不合逻辑的规定或条件所造成的无法摆脱的困境、难以逾越的障碍，表示人们处于左右为难的境地，或者是一件事陷入了死循环，或者跌进逻辑陷阱，等等。 当一个人一旦提出申请的时候，恰好了证明这个人是一个正常人，而“只有疯子才能获准免于飞行”，那么，这个人无法在疯了的时候提出申请，所以这个人还是在劫难逃，就不能免于飞行。 One of the most interesting books of the 20th century was the novel, Catch 22. In the novel, the term "a catch 22 situation" was introduced. 20世纪最有趣的书之一是小说《第22条军规》。 在这部小说中，人们引入了“第22条军规左右为难”这一术语。 term 英 [tɜ:m]  美 [tɜ:rm]  n.术语;期限;学期;条款 vt.把…称为;把…叫做 The term has nothing to do with catching anything. 这个术语和抓住任何东西完全无关。 It has a much deeper meaning and it describes a kind of logical  conundrum  that"s worth exploring. 它有着更深刻的意义，它描述了一种值得探索的逻辑难题。 conundrum 英 [kəˈnʌndrəm]  美 [kəˈnʌndrəm]  n.谜语;难解的问题 First, it"s important to put the phrase into context . 首先，把这个短语放到上下文中很重要。 context 英 [ˈkɒntekst]  美 [ˈkɑ:ntekst]  n.语境;上下文;背景;环境 In the novel, a group of American bomber pilots is on an island in the  Mediterranean . 在小说中，一群美国轰炸机飞行员在地中海得去的一个小岛上。 bomber英 [ˈbɒmə(r)]  美 [ˈbɑ:mə(r)]  n.轰炸机;投弹手 Mediterranean 英 [ˌmedɪtəˈreɪniən]  美 [ˌmɛdɪtəˈreniən, -ˈrenjən]  adj.地中海的;地中海地区的;地中海居民的 They face death almost every day when they fly their  bombing  missions. 他们在执行轰炸任务时几乎每天都面临死亡。 Many have already lost their lives. 许多已经失去了生命。 The remaining pilots know that it is only a matter of time before they will be the next  victims . 剩下的飞行员知道他们成为下一个受害者只是时间问题。 One of the characters in the novel is a doctor. 小说中的其中一个角色是医生。 It is his job to see that the pilots are fit to fly. 他的工作是看飞行员是否适合飞行。 In  particular , there is a rule that says he has to  ground  anyone who is crazy. 特别是，有一条规则说他必须让任何疯狂的人停飞。 To  ground  them means to remove them from  active duty  so that they don"t fly. 让他们停飞意味着把他们从现役中除掉，这他们就不会飞了。 active duty 英 [ˈæktiv ˈdju:ti]  美 [ˈæktɪv ˈduti]  n.现役 Some of the men believed in the  principles  that they were fighting for. 有些人相信他们为之奋斗的原则。 They were willing to give their lives for their country. 他们愿意为了自己的国家牺牲自己。 But to other, this was crazy. 但是对其他人而言，这太疯狂了。 They thought the whole thing was insane . 他们认为整件事情都是疯狂的。 insane 英 [ɪnˈseɪn]  美 [ɪnˈsen]  adj.疯狂的;精神病的;非常愚蠢的 One of them, Yossarian, wanted out. 他们中有一个，Y，想要退出。 He was friends with the doctor, and he wanted the doctor to ground him. 他是医生的朋友，他想医生让他停飞。 When Yossarian asked the doctor to ground him, the doctor replied: "You"re wasting your time.

He"s crazy," the doctor replied.  “这没有意义，他是个疯子。”医生回答。 "Crazy people can"t decide whether you"re crazy or not." “疯子并不能决定你是疯了还是没疯。” "Clevinger isn"t crazy!

音频 A number of scientists are emphasizing the tremendous challenges that will soon be faced when the depletion of fossil fuel supplies coincides with an alarming increase in the global population. They highlight agriculture which is heavily dependent not only on gasoline to fuel machinery, but also on the petrochemicals necessary to manufacture synthetic fertilizers and pesticides. Without these petrochemicals, crop yields would be only a fraction of what they are today. To assume that an abundant source of renewable energy will address this challenge is to ignore the vital non-fuel uses of petrochemicals.Then there is the challenge posed to the current levels of mobility. As a fuel, gasoline is unrivalled in its portability. Electricity requires bulky batteries and hydrogen is notoriously difficult to store. Biofuels might seem like an alternative, but the energy consumed when converting corn into bioethanol, for instance, greatly exceeds the output when the fuel is utilized. In any case, once we reach a crisis in the food supply, it will not make sense to divert food crops to other uses. Although there seems to be a widespread belief that the era of oil dependency is coming to an end due to some technological remedy, this may be mistaken. Relying on such an assumption can lead to complacency and a failure to take precautions. Experts may not be able to come up with the kind of solution that can lead to a pain-free transition. Scientists warn that relying on alternative resources might only support half of the global population. The absence of realistic alternative to fossil fuels will mean that the first priority will be to curb the demand for food. （The article implies that the general population assumes that things will get better.） （Petrochemicals are used to manufacture pesticides which are important for agriculture.） （There is a widespread belief that the era of oil dependency is coming to an end.）（The aim of the article is to highlight the seriousness of the situation.） （As fossil fuels become depleted there may not be enough food for the growing population.）（Curbing the demand for food will require a reduction in the global birth rate.）

爱的心理人类 One of the most important human emotions is love.最重要的情感之一就是爱。 However, there are many different kinds of love.然而，有许多不同种类的爱。 Romantic love is certainly one of the most interesting kinds of love.浪漫的爱情当然是最有趣的一种爱情。 It can be beautiful, wonderful, and heartbreaking, sometimes all at the same time.它可以是美丽的，美妙的，令人心碎的，有时同时发生。 Romantic love can make our lives full and meaningful, but it can also be an escape from loneliness and suffering.浪漫的爱情能使我们的生活充实而有意义，但它也能使我们摆脱孤独和痛苦。 Besides romantic love,  another kind of love is between parents and children.除了浪漫的爱情，另一种爱是父母和孩子之间的爱。 If romantic love has a purpose,neither psychology nor biology has discovered it.如果浪漫的爱情有目的，心理学和生物学都没有发现。 However, throughout history, philosophers have offered opinions about it.然而，纵观历史，哲学家们对此提出了自己的观点。 The Greek philosopher, Plato, said love makes us complete.希腊哲学家柏拉图说过，爱使我们完整。 He relates a comic story in which humans originally had 4 arms, 4 legs and 2 faces.他讲述了一个喜剧故事，在这个故事中，人类最初有4条胳膊、4条腿和2张脸。 Then, when they angered the Gods, they were cut in half.然后，当他们激怒了众神，他们被切成两半。 Since then every person has been searching for their soulmate, the other half  of his or her self.从那时起，每个人都在寻找自己的灵魂伴侣，另一半的自我。 Another philosopher believed that love is an illusion.另一位哲学家认为爱情是一种幻觉。 In his view, people fall in love because they believe the other person can make them happy.在他看来，人们坠入爱河是因为他们相信别人能让他们快乐。 But in fact, this is just an illusion designed to make us have children.但事实上，这只是一个假象，是为了让我们有孩子。 Once we have children, we are right back to where we were, still searching for  happiness.一旦我们有了孩子，我们就回到了过去，仍然在寻找幸福。 For nature this is a success, because we have children to maintain our species.对大自然来说，这是一个成功，因为我们有孩子来维持我们的物种。 But it leaves us still searching for something more.但它仍然让我们寻找更多的东西。 According to this philosopher what is the real purpose of love? It"s designed to maintain our species.根据这位哲学家的观点，爱的真正目的是什么?它的设计是为了保护我们的物种。 If something is an illusion, it isn"t what it seems to be.如果某件事是一种幻觉，它并不是它看起来的那样。 Some people say love can be a disguise for our sexual desires or a biological trick to make us to have children.有人说，爱可以是我们性欲的伪装，也可以是我们生儿育女的生理伎俩。 In Buddhism, romantic love is seen as an attempt to satisfy our desires.在佛教中，浪漫的爱情被视为满足我们欲望的一种尝试。 These desires are a defect, something we need to overcome.这些欲望是一种缺陷，是我们需要克服的。 The way to free ourselves from suffering is to remove desires.把自己从痛苦中解放出来的方法就是去除欲望。 Once free of desires we can reach a state of peace and wisdom.一旦摆脱了欲望，我们就能达到一种平静和智慧的状态。 This state of being is called nirvana.这种存在状态被称为涅磐。 According to Buddhism how can we free ourselves from suffering? overcome our desires根据佛教，我们怎样才能从痛苦中解脱出来?克服我们的欲望 Other kinds of love include the love between a parent and child.其他类型的爱包括父母和孩子之间的爱。 In one of China"s greatest classical novels, Dream of the Red Chamber, love is presented as a state of foolishness.在中国最伟大的古典小说之一《红楼梦》中，爱情被描绘成一种愚蠢的状态。 A young man falls in love with a beautiful woman who tricks and makes a fool of him.一个年轻人爱上了一个美丽的女人，她欺骗并愚弄了他。 This results in conflicting emotions of love and hate which tear him apart.这导致爱与恨的情感冲突，将他撕裂。 To cure him, a priest gives him a magic mirror.为了治好他，牧师给了他一面魔镜 The priest tells him to look into the reverse side of the mirror, but never to look in the front side.牧师告诉他要照镜子的背面，但不要照镜子的正面。 What side of the mirror is he supposed to look into? the reverse side他应该朝镜子的哪一面看?背面 When the young man looks into the mirror, he doesn"t like what he sees, so he  looks into the forbidden side, the front side.当年轻人照镜子时，他不喜欢他所看到的，所以他看的是禁忌的一面，正面。 There he sees the lovely image of his love, who invites him into the mirror to be with her.在那里，他看到了他爱的可爱的形象，谁邀请他进入镜子与她在一起。 He does this several times until he is finally dragged away in chains.他这样做了好几次，直到最后被人用链子拖走。 He dies while looking into the mirror.他在照镜子的时候死了。 Perhaps the point of the story is that all such attachments should be avoided.也许这个故事的重点是，所有这些依恋都应该避免。 Why does the young man look into the forbidden side of the mirror ? he doesn"t like what he sees in the mirror.为什么这个年轻人要看镜子的禁忌面?他不喜欢他在镜子里看到的东西。 What finally happens to the young man? He is dragged away in chains and dies.最后这个年轻人怎么样了?他被铁链锁着拖走，死了。 He enters the mirror to be with his love and satisfy his desires.他进入镜子与他的爱和满足他的欲望。 once free of desires we can reach a state of peace and wisdom一旦摆脱了欲望，我们就能达到一种平静和智慧的状态 The way to free ourselves from suffering is to remove desires.把自己从痛苦中解放出来的方法就是去除欲望。 He is dragged away in chains and dies while looking into the mirror.他被锁链拖走，在照镜子时死去。 The priest tells him to look into the reverse side of the mirror, but never to look in the front side.牧师告诉他要照镜子的背面，但不要照镜子的正面。 A famous French writer, Simone de Beauvoir has another point of view.法国著名作家西蒙·德·波伏娃有另一种观点。 For her, love is the desire to integrate with another, like in a great friendship.对她来说，爱是渴望与他人融合，就像在一段伟大的友谊中。 However, it is important that lovers not become too dependent on the other person.然而，重要的是恋人之间不要太依赖对方。 Becoming dependent on another person can lead to boredom or power games.依赖他人会导致无聊或权力游戏。 Lovers should support each other in discovering themselves and developing their potentials.情侣们应该互相支持，发现自己，开发自己的潜力。 In this way, romantic love can enrich the world.这样，浪漫的爱情可以丰富世界。 According to this writer, lovers should avoid becoming too dependent on the other person.根据作者的观点，情侣们应该避免过于依赖对方。 Falling in love can be exciting and frightening.坠入爱河既令人兴奋又令人恐惧。 Maybe we lose ourselves and maybe we find ourselves.也许我们失去了自己，也许我们找到了自己。 Will you dare to find out?你敢知道吗?
