TED演讲集 那些匪夷所思的新奇思想201602/426572Im in the Mexican gallery in front of what looks like a giant stone horseshoe-its about 20 inches (50 cm) long and about 4 inches (10 cm) thick and is made of a very beautiful grey-green speckled stone. When it first came to the British Museum in the 1860s they thought that it was a yoke for something like a carthorse-but there were two immediate problems with this theory: first the object is very heavy, its about five or six stone (35 kg)-too heavy even for a horses neck-and secondly, there were no carthorses or draught animals in Central America until the Spaniards brought them from Europe in the sixteenth century.在大英物馆的墨西哥厅,有一件形似大型石制马蹄铁的物品,长约四十厘米,厚十二厘米,由美丽的灰绿色斑点石制成。1860年它刚到大英物馆时,人们以为它是马匹之类的拉车的轭。但很快疑问便出现了:首先,这件东西重约四十千克,背起来过于沉重;其次,在16世纪西班牙人进入美洲之前,美洲其实没有任何用于负重拉拽的动物。It was only just over 50 years ago that it was generally understood that these stone carvings had nothing to do with animals; they were meant to be worn by men. They represent the padded belts made of cloth or basketwork worn to protect the hips during ancient Central American ball games. Indeed some of these stone belts may have been moulds used to shape lighter cloth or leather padding, but the one we have in the British Museum is made of solid stone, so heavy that if it was worn it can only have been very briefly. Nowadays it would perhaps be for a quick photo call, but we dont actually know exactly when or how it might originally have been worn.直到五十多年前,人们制品与动物无关,而是给人类穿戴的。它类似用布的软垫,戴在腰间,在古代中美洲的球类运动中用于保护臀部。有些石头腰带可能只是模具,成品则由较轻的布料或皮革制成。而大英物馆所藏的这一件也太过沉重,即使戴不了太长时间。我们无法准确了解古人佩戴它的原因何在,也不了解他们在什么情况下会佩戴它,又是如何佩戴的。We asked the leading expert on these games, Michael Whittington, what he thought these stone belts were for:中美洲球类运动专家迈克尔惠廷顿认为,这些腰带主要是在仪式使用的:;I believe these were ceremonial objects.Wearing an object thats 75-100 lbs around your waist during an athletic competition will slow you down considerably, so they probably were worn as part of the ritual ceremonies at the beginning of the game. 我认为这些是仪式用具。在运动比赛中戴着三四十公斤重的东西会让人动作变慢。因此应该是在比赛前的宗教仪式中使用的。它们象征着比赛中人们真正会使用的腰带。201501/354548The best place to see what effect global warming is having on the permafrost在永久冻土上是最好的观察全球变暖影响的地方is the many lakes found in this region.在这一地区有很多湖泊And thats whats brought ecologist Katey Walter to this frozen wasteland.这吸引了生态学家 凯蒂沃尔特 到来She believes shes aly detected the first signs她相信她已经发现了第一个征兆that methane is being released from the permafrost.甲烷已经开始从永久冻土释放Whats happening is that the permafrost is melting and thawing永久冻土正在融化and slumping into the bottoms of the lakes.滑入湖泊的底部Those dead plants thaw out,这些死掉的植物解冻and they ferment at the bottom of the lake在湖底发酵and methane is the by-product. Methane comes out.甲烷同时产生,甲烷从湖里释出If Kateys right, then we should be able to find methane almost everywhere.如果凯蒂是对的,我们应该能发现到处是甲烷Ah, this is the ice. Ive got to the ice.啊,这是冰,我触到了冰Look at that, thats beautiful! Oh, theres bubbles.看那,真是漂亮噢,那是气泡The ice is over three feet thick这冰有一米厚and its full of bubbles trapped inside it.很明显冰里面截留大量的气泡The trouble is it wont stay trapped in these bubbles for long.问题是冰不能截留这些气泡太久When the ice thaws in spring, the gas will escape.当冰在春天融化,气体会逃走201509/401497栏目介绍:搞笑英语轻松学通过不同的搞笑生活片段来学习日常口语,领域涉及生活的各个方面,让我们边看视频边学英语。正宗地道的口语,假一罚十。美剧电影真人秀都看过了之后还能看什么学口语呢?当然是看这些双语视频啦!又好玩,又原汁原味,又顺便学一两句地道英语,多痛快!快来看看吧!201509/397801
