Presidents Barack Obama and Vladimir Putin are to meet for the first time in two years during this week’s 70th session of ed Nations General Assembly.在本周联合国成立七十周年峰会上,奥巴马和普京进行了两年来的首次会面。It’s expected the two leaders will discuss the Syria conflict and Russia’s military buildup in the war torn country.两国领导人有望共同探讨叙利亚冲突,以及俄罗斯在这个备受战争蹂躏国家的军事建设。On Sunday Obama called on wealthy nations to act to help refugees.周日,奥巴马呼吁富裕国家采取行动来帮助难民。“Today some 60,000,000 men, women and children have been forced from their homes, many by conflicts in the Middle East and Africa,And those countries that can must do more to accommodate refugees but our efforts must be matched by the hard work of diplomacy and reconciliation to end conflicts that so often tear societies apart.”“今天约有六千万男子、妇女和儿童被迫离开家园,许多是因中东和非洲国家的冲突,那些国家应采取更多措施容纳难民,但我们的努力必须匹配外交与和解工作,以结束分裂社会的冲突。”Ahead of today’s meeting, in a recorded interview with US networks Vladimir Putin said Syria’s president deserved international support.今天会议之前,在一个美国网络采访纪录中,普京表示叙利亚总统应当得到国际社会的持。“There is only one legitimate army in Syria and it’s the army of President Bashar al-Assad. In my view, providing military support to illegitimate structures is not in keeping with the principles of modern international law or with the ed Nations charter. We (Russia) support only legal and governmental structures.”“在叙利亚只有一个合法的军队,就是巴沙尔·阿萨德总统的军队。在我看来,为不合法的组织提供军事持是不符合现代国际法或联合国宪章。我们(俄罗斯)只持具有合法和政府的组织。”President Putin is scheduled to address the ed Nations General Assembly today for the first time in a decade.普京总统计划今天在联合国大会上发表讲话,这是十年来的首次。译文属。 /201509/401427TED演讲者们对这个世界各抒己见。201505/373009


  What makes Swartkrans really special斯瓦特克朗斯的特别之处在于is a unique collection of animal bones found in the same layer同一岩层里发现了一组独特的动物遗骨which Bob thinks are evidence that our ancestors could control fire.鲍勃认为那是我们祖先使用火的据We suddenly found numerous examples of bone that had been burnt,我们突然间发现了大量被灼烧过的遗骨suggesting that a very repetitive process had been going on there说明这是个重复发生的过程and that bones were being regularly burnt in fires还有在靠近山洞入口的地方close to the caves entrance.那些骨头是定期焚烧的In the process,在人类的发展进程中our ancestors had gone from being preyed on by animals我们祖先从被野兽捕食to using fire to frighten them away and even to hunt them.发展为用火驱赶野兽 甚至猎捕它们Once prey, they were now predators.曾经的猎物成为了猎人But for Travis,但对于特拉维斯the burnt bones represent an even more intriguing possibility.烧焦的遗骨代表一个更有趣的可能性Homo erectus might have used fire at Swartkrans in order to cook.斯瓦特克朗斯的直立人有可能用火烹煮If we could prove cooking at this site, it would be remarkable.如果能明这个遗址有烹煮现象 将是个了不起的发现This part of the site is a million years old,这部分遗址有一百万年的历史了so it would be the earliest evidence of cooking anywhere in the world.所以这将是全世界最早的烹煮据201505/375207

  But time is like a river in another way.不过时间似流水还有另一层含义It flows at different speeds in different places.其在不同地点有着不同速度And that is the key to traveling into the future.而这正是穿梭于时间的关键所在The idea was proposed by Albert Einstein这一概念在100多年前over 100 years ago.由阿尔伯特·爱因斯坦提出He realized that there should be places where time slows down他认为时间在一些地方会减慢and others where time speeds up.而在另一些地方则会增快He was absolutely right,这话可是千真万确and the prove is right above our heads, up in space.据就在我们头顶的那片太空中This is the Global Positioning System, or GPS.这是全球定位系统,又叫GPSA network of 31 satellites是由绕地球轨道运行的in orbit around the earth.31颗卫星形成的网络The satellites make satellite navigation possible.正是这些卫星使卫星导航变为可能But they also reveal that time runs faster up here但同时也表明than it does down on earth.在这里时间流逝得比地球上快Inside each spacecraft is a very precise clock.每个航天器内都有一个十分精确的时钟But despite being so accurate,尽管已经十分精确 they all gain around但他们每天都大约会走快a third of a billionth of a second every day.十亿分之一秒的三分之一The system has to correct for the drift.系统必须更正这一偏差Otherwise that tiny difference would upset the whole system,否则这细微的差异会扰乱整个系统causing every GPS device on earth致使地球上所有GPS设备to go out by about six miles a day.每天出现约6英里的误差You can just imagine the mayhem that would cause.其引起的混乱可想而知The problem doesnt lie with the clocks.问题并不在于时钟They run fast because time itself runs faster here than时钟走得快是因为在这里时间本身it does down below,就比在地球上快and the reason for this extraordinary effect产生这种奇异现象的原因is the mass of the earth.在于地球的巨大质量Einstein realized that matter drags on time,爱因斯坦意识到,物质滞延时间slows it down like the slow part of a river.像河流的缓流部分那样令时间减速The heavier the object, the more it drags on time,物体越重,滞延时间越长and this startling reality这一惊人的事实is what opens the door to the possibility of time travel to the future.打开了一扇穿越未来的希望之门I admit this is a difficult concept to understand,我承认这个概念很难理解so lets take a simple example.所以让我们来看一个简单的例子This is the Great Pyramid of Giza.这是吉萨的大金字塔It weighs over 40 million tons,重达4000多万吨and like all heavy things,与其他所有沉重的物体一样its actually slowing down time.它会减慢时间The effect is small,不过影响微弱billions of times smaller than that of the earth.只及地球影响力的几十亿分之一But if we exaggerate it drastically,但是如果大幅放大这种影响You can see the principle at work.就能看到这种原理在起作用201507/386415。


  Today, only the hardest outcrops are left behind.今天只剩下了最坚硬的岩层Theyre called sea stacks.这就是所谓的海蚀柱But even they will eventually be ground away.但是它们也将慢慢地被磨掉The oceans influence our planet海洋对我们星球的影响in many far more subtle and profound ways.更多的是以微妙深奥的方式进行They drive the climate.它们改变着气候They harbour creatures that deliver oxygen to our atmosphere.将氧气输送到大气层And below the oceans surface is an extraordinary network of currents在海洋表面以下是一片独一无二的洋流体系that are critical to the wellbeing of all life on Earth.这对地球上所有的生命良性发展起到关键作用But four and a half billion years ago, when our planet was born,但是450亿年前,地球刚刚诞生it was just a molten inferno.它不过是一个融化的地狱There was no place for any liquid water at all.根本没有液体存在的可能Yet the ingredients needed to create water were there,但是仓创造水的成分都存在locked away deep inside the Earth when the planet formed.在地球形成的时候被紧紧压在了地球里面As the first volcanoes erupted,第一次火山爆发的时候one of the gases that billowed out was steam.第一股爆发出来的气流中就有蒸汽And as the planet cooled, it formed clouds.等到星球冷却下来就形成了云201511/408448With the headteachers safely out of sight, normal service resumes in the classroom.当校长离开视线范围内后,教室里又恢复了平时的样子All in this together Everyone...大家一起嗨呀Excuse me!打扰一下We will see that Were all in this together.大家一起见自己Phoebe, listen to me!

  Its got a squashed nose, bulging eyes, small horns, and abundant whiskers. In fact, the face looks like a cross between a Chinese dragon and a Pekingese dog, and not friendly at all! It looks a bit like an oriental gargoyle, and that is pretty well what it was.It would have had a similar position to a gargoyle, high up on a temple or a grand house. The features of the face when you look at them closely are pretty rough, and its obvious that its been made by pushing the wet clay into a fairly simple mould. This is clearly a mass-produced object. But that is why its so interesting, because this is just one of tens of thousands designed to cover roofs that would once have been thatched, but in prosperous Silla Korea, were tiled with objects like this.阔鼻,鼓眼,细角,胡须很多,看起来像是中国龙与京巴的混合体。它十分类似同期产于中国唐朝的瓦片,但它绝非中国制造。中国龙通常有一张大嘴,而这个动物的嘴小且具有攻击性。整个瓦片的造型也颇为粗犷,一点儿也不中国。它看起来就像个东方的滴水兽,而这也正是它的用途。它曾被安放的位置与西方的滴水兽类似,高踞于庙宇或豪宅的屋顶。瓦片的面部细节极为粗糖,显然只是将湿土按压进一个简单的模具制成的。它很明显是大规模量产的瓦片之一,而这正是我们对它感兴趣的原因。人们的屋 顶曾经只用茅草覆盖,而今在繁华的新罗,人们制造出成千上万件类似的瓦片,覆盖在屋顶之上。Why did the Silla want to build such a grand capital, and why did they need so many new houses? The Korean specialist Jane Portal explains:朝鲜半岛专家白珍士解释了新罗为何要将庆州修建得如此繁华,又为什么需要如此多的新建筑:;The city of Kyongju was based on the Chinese capital Changan, which was at the time the biggest city in the world, and Kyongju developed hugely once Silla had unified the Korean peninsula, or most of it. A lot of the aristocrats from the kingdoms which were defeated by Silla had to come and live in Kyongju, and they had magnificent houses with tiled roofs. And this was a new thing, to have tiled roofs, so this tile would have been a sort of status symbol for them.;庆州是模仿中国的首都长安建造的。长安是当时世界上最大的城市之一。新罗征了朝鲜半岛的大部分地区之后,庆州立刻飞速发展起来。许多战败国的王公贵族来到庆州居住,他们需要覆瓦的豪宅。瓦顶建筑对当时的庆州来说是新鲜事物,因此这样的瓦片是某种地位的象征。201510/404001
