由于英语并非我们的母语，因此用英语演讲是有一定难度的。那么下面来看看如何提高自己的英语演讲水平，需要注意哪些问题？ 一、形态上要注意的事项 演讲时的姿态会给听众留下某些印象，比如谦虚或畏缩。尽管个人性格和平日习惯对演讲有相当大的影响，但还是存在一些演讲的轻松姿势。使身体放松，也就是不要过度紧张。过度紧张不仅会表现出笨拙、僵硬的姿势，还会对舌头的运动产生不良影响。 有一种方法就是张开双脚，与肩同宽，使整个身体保持稳定。还有一种方法就是想办法分散和缓解压力。比如，把一只手轻轻放进口袋里，或触碰桌子，又或是握住话筒等。 总而言之，身体必须站直，抬头挺胸，表情自然，面带微笑，这一点平时可以看着

表达技巧是朗读在生活中的运用，演讲时自然而然的朗读更是准确流畅表达技巧的坚实基础。如何提高英语演讲的流畅度？ 1.语音技巧 要有出色的演讲，必须有好的发音效果，语音训练自然必不可少。发音的基础之一是呼吸。响亮、动听的声音与科学的呼吸训练是分不开的。其次，吐字发音要做到音节正确、准确，完全符合普通话的发音标准。音量大小的变化和科学的运气更有利于准确地表达思想感情。 2.语调技巧 语调包括停顿、重音、升降、快慢等要素。语调训练是英语演讲时表达的重点和难点。平时必须加强这方面的训练。语速、节奏的把握也是表达感情的重要手段，也需要多加训练。 3.训练技巧 (1)训练生动自然的朗读。 训练

How do you define ... &quotDaily active usage&quot seems like a really dangerous term to be optimizing. Taken,你是如何定义……过于美化“每日活跃参与度”这个数值似乎是一件危险的事，taken alone, it is, but you didn&#39t let me finish the other metric, which is, we&#39re watching for conversations and conversation chains.确实，如果你单独讨论这个数值的

14 years ago, I gave a commencement speech at another New Jersey school.14年前，我在新泽西的另一所学校做了一场毕业演讲。Through the magic of Google search, I was able to do a &quotback to the future moment,&quot通过谷歌搜索的魔力，我得以“回到未来时刻”，looking back on my words to see if any of what I had to say to the class of 2001 stood up

We had to get lucky in a lot of different ways. And sometimes, it&#39s better to be lucky than good.在很多方面我们都需要幸运的眷顾。有时，运气比正确操作更重要。In this case, we were both, I like to think. But light had to come from the black hole.我认为这一次，我们不但操作正确，运气也很好。但我们需要接收来自黑洞的光线。It had to come through intergalactic space, th

Fortunately, in the 1950&#39s, conformity was encouraged -- though we were also in a period of transition.幸运的是，20世纪50年代，人们鼓励随大流--虽然当时我们也处于转型期。Women were finding our voices at Wellesley, but we were also expected to be young ladies -- except perhaps during that occasional outing to Boston.在韦尔斯利学院妇女有话

You&#39ll see here that some light from behind it gets lensed, and some light does a loop-the-loop around the entire orbit of the black hole.你现在看到的是在黑洞后面的一些光透过它，有些光的确会一直绕着黑洞转。But when you get enough light from all this hot gas swirling around the black hole,但如果光足够多，它们来自黑洞周围的高温气体中，then you wind up se

Let&#39s see what you guys are asking. I mean, this is -- generally, one of the amazing things about Twitter is how you can use it for crowd wisdom,让我们看看你们在问什么。我觉得，这是——总体而言，推特的特点之一在于它能够集中大众智慧，you know, that more knowledge, more questions, more points of view than you can imagine, and sometimes, many

This is a very powerful black hole. Not by universal standards, it&#39s still powerful,这是一个强有力的黑洞。虽然不是公认的，但它依然非常强大，and from the north and south poles of this black hole we think that jets are coming.在这个黑洞的北极和南极，我们认为射线正从这两段过来。Now, we&#39re too close to really see all the jet structure, but it&#39s th

Well, do you, though? Because that&#39s the core question that a lot of people want to know.并且——安德森：你是这么想的吗？这是许多人想问的一个核心问题。Surely, Jack, you&#39re constrained, to a huge extent, by the fact that you&#39re a public company, you&#39ve got investors pressing on you,当然，杰克，你在很大程度上受到约束，因为这是一家上市公司，你会收到投资者的

So say EPC. EPC. Say it, EPC! EPC!说EPC！EPC！说EPC！EPC！&quotI like to say it with pride now, when you do it, do it well, and make sure that it counts. You&#39re not down with a discount.&quot“我喜欢自豪地说出来。如果你要偷情，就尽情地去吧，好好享受这其中的激情全没半点折扣。”You down with EPC? Yeah, you know me!你对EPC无法自拔吗？是啊，你懂的！Now, I had alw

Good morning, Mayor Redd, President Barchi, Chancellor Haddon, governors, trustees, alumni, family, friends,早上好，雷德市长，巴奇校长，哈登校长，理事们，校董们，校友们，家长们，朋友们，and especially, the graduating class of Rutgers-Camden, congratulations!尤其是罗格斯大学卡姆登分校的毕业生们，恭喜你们！I want to thank you for inviting me here today on one of

Life is a long, bumpy road, but that makes for an exciting ride.人生是一条漫长崎岖的道路，却也因此成为一段令人兴奋的旅程。Choose a direction, and if the road turns -- turn!选择一个方向，如果这条路转弯了--那就随着转吧！If there is a fork in the road -- take it!如果路上出现了岔路口，那就做出选择吧！It&#39s OK to map out your future -- but do it in pencil.你可以规划自己的未来，但要用铅

So imagine, that you are transforming, inspiring, and improving not only others but yourself along the way.想象一下，你不仅不断改进、启发和改善他人的同时，也在改变自己。This will make you better and stronger!这将使你变得更优秀，更强大！Better and stronger: you have grown here together, you have learnt here together,更优秀，更强大：你们在这里一起成长，在这里一起学习，yo

Before the Soul ever played a down, we found four needy charities and gave away more money than we brought in.在费城灵魂队刚能够打个一档时，我们发现有四家慈善机构很缺钱，就向他们捐钱，捐的钱比我们挣的还要多。We were having fun playing football and Robin Hood!我们一边玩橄榄球一边当罗宾汉，感觉很开心！But then on one bitter cold night in 2006, while I was staying in Phi

We&#39re ordering it the right way, but we&#39re also simplifying the rules so that they&#39re human-readable我们以正确的顺序排列信息，但同时我们也在简化规则，使其简单易懂，so that people can actually understand themselves when something is against our terms and when something is not.这样人们就能理解哪些行为违反了条例，哪些没有。And then we&#39re making

The song is about cheating on your significant other.这首歌是关于出轨的。Now, around the time that this song was in heavy rotation,在这首歌特别流行的时候，biologists were in deep discussion about whether bird species,生物学家们深刻讨论了鸟类，notably songbirds and waterfowl were actually monogamous or not.特别是夜莺和水禽类是否真的是一夫一妻制。See, for

You can&#39t beat the bandwidth of a 747 filled with hard discs.没有哪个网络比一架满载硬盘的波音747飞机更快的了。And so, I guess a few weeks or a few months ago, on a computer screen somewhere, this started to come into view. This moment.那么我猜，在几周或几个月前，在某地一台电脑的显示器上，黑洞的形象在那一刻渐渐成形。Well, it took a long time. I mean, look at t

This brings me to my final story -- about encouraging transformational change in others.这就引出了我最后的故事--关于鼓励他人进行变革。The real heroes of that little story that I&#39m going to tell you are really my great colleagues at the International Monetary Fund.我要讲的这个小故事的真正英雄，是我在国际货币基金组织的出色的同事。In 2011 -- at the heig

Now embracing &quotwe&quot doesn&#39t absolve you from the responsibility to lead.现在接受“我们”的力量并不会免除你们引领社会的责任。This world needs its young people to lead and to lead by example.这个世界需要年轻人来引领，需要年轻人以身作则。To walk that walk, and to do that work. So confound expectations.走该走的路，做该做的工作。所以把理想先放一边吧。Inspire others!

And while you are making a difference at school, at home, at work,当你们在学校、在家里、在工作中有所作为的时候，many of you will also want to make a bigger difference and take a larger perspective on the pressing issues of our time.你们中的许多人还希望发挥更大的作用，从更广阔的角度看待我们这个时代的紧迫问题。Protection of our planet, eradication of poverty, re

Just to back up a bit, we asked ourselves a question: Can we actually measure the health of a conversation, and what does that mean?让我们倒回去一点，我们问了自己一个问题：我们是否能测量对话的质量？而对质量的定义又是什么？And in the same way that you have indicators and we have indicators as humans in terms of are we healthy or not,就像你我作为人类会有显

And that took some work. And as we dived into that, we realized some of the issues with the fundamentals.这花了一点时间。当我们开始关注这方面时，我们意识到一些原则性的问题。We could do a bunch of superficial things to address what you&#39re talking about, but we need the changes to last,为了达成你所说的目的，我们可以采取一系列浅层措施，但我们需要找到可持续的改进措施，and t

It&#39s the red circle, that&#39s terrifying. No, really. Black holes really are the central mystery of our age,这个红色的圈太吓人了。你在开玩笑。黑洞可谓是我们这个时代的中心之谜，because that&#39s where the quantum world and the gravitational world come together. What&#39s inside is a singularity.因为它是量子世界与引力世界的交合点。黑洞的中心是一个奇点。And th

Now, hip-hop song references are a really good tool for teaching content to students from hip-hop culture or urban communities.对于教导嘻哈文化背景下，或城市社区背景下的学生，嘻哈的确是个绝佳的工具。And I use it intentionally to connect to those students, tapping into vocabulary that they already know and systems that they already com

Yeah, I mean, I think you&#39re spot on, but that goes back to the incentives. Like,是的，我觉得你讲的正中要害，但这反过来回到了刚才所说的动机问题。one of the choices we made in the early days was we had this number that showed how many people follow you.在早期，我们设计的系统是这样的：系统会显示关注你账号的人数。We decided that number should be big and bold,

But as the names of dead European kings and the body parts of dissected animals begin to fade,随着逝去的欧洲君王的名字、解剖过的动物身体构成开始从脑海中淡去，the true value of your days on the hill, in Boston, or in Grafton will become more and more apparent.你们在这座山上、在波士顿、在格拉芙顿的那些日子的真正价值会变得越来越清晰。For by studying here at Tufts, you,

How y&#39all doing? Good. I came here to give you a science lesson大家好吗？非常好。今天我想给大家上一堂科学课，about animal mating systems and why defining monogamy has been a challenge for scientists.关于动物交配体系，以及为什么对科学家来说定义一夫一妻制很难。But you won&#39t need a textbook or to download an online lecture.这堂课你们不需要什么课本，也不需要下载讲座视频。A
