【新闻精讲】You might think frogs catch insects ‘cause their tongues are sticky. ;But why is the tongue sticky, and how does it actually adhere to these insects at these very high accelerations?;Those are the questions Alexis Noel, a PhD candidate in mechanical engineering at Georgia Tech, wanted to answer. So she and her team got frog tongues from a dissection lab, and tested their consistency. Ten times softer than human tongues. A texture more like brain tissue. ;Their tongue is very much like a sponge. It#39;s infused with this thick, viscous saliva.;That saliva was their next study subject. ;And in order to test the saliva we had to get about a fifth of a teaspoon of fluid. Which is a lot of saliva, in a frog#39;s case.; They put the saliva in a rheometer, a tool that can measure viscosity. And they found that frog saliva is what#39;s called a #39;shear-thinning fluid#39;—its viscosity changes, depending on conditions.You might be more familiar with a different shear-thinning fluid. ;Ketchup. When you smack the bottom of the ketchup bottle you#39;re actually invoking shear forces within the ketchup itself. And ketchup, because it#39;s shear thinning, its viscosity actually drops and allows it to slide out of the bottle easily.;So back to our frogs: the tongue shoots out, hits the bug and deforms around it. That impact is like a smack on a ketchup bottle—it changes the saliva from thick and sticky to more watery, free to flow all over the bug. Then the tongue bounces back, like a bungee cord, and the saliva thickens up again. What#39;s next is beyond weird.;Frogs actually take their bulbous eyeballs and bring them down into their mouth cavity and use their eyeballs to shove the insect down the throat.; That force turns the saliva watery again, ;and the insect slides down the gullet.; The study is in the Journal of the Royal Society Interface.【视频讲解】You might think frogs catch insects ‘cause their tongues are sticky. ;But why is the tongue sticky, and how does it actually adhere to these insects at these very high accelerations?;你可能认为,青蛙因为要抓昆虫,所以它们的舌头都是粘性。但,为什么舌头是黏黏的?舌头是如何能极其快速地抓住昆虫呢?adhere to stick to 粘附Adhere1. 遵守例:All members of the association adhere to a strict code of practice.所有该协会的成员都遵守严格的业务守则。2. 紧贴,粘住例:Small particles adhere to the seed.微小的粒子紧贴着种子。Those are the questions Alexis Noel, a PhD candidate in mechanical engineering at Georgia Tech, wanted to answer. So she and her team got frog tongues from a dissection lab, and tested their consistency.乔治亚理工大学生物工程学士Alexis Noel想回答这些问题!所以,她和她的团队从解剖实验室取得青蛙的舌头,然后检查粘度。Dissect1. 解剖2. 剖析People want to dissect his work and question his motives.人们想剖析他的作品,质疑他的动机。Consistency1. 黏稠度2. 连贯性; 一致性例:She scores goals with remarkable consistency.她以非凡的连贯性进球得分。Ten times softer than human tongues. A texture more like brain tissue. ;Their tongue is very much like a sponge. It#39;s infused with this thick, viscous saliva.;青蛙的舌头比人类的柔软十倍,纹理更像人类大脑。“它们的舌头像海绵,它吸收浓厚,粘性的唾液”Sponge 海绵Infuse 注入 (某种特性)例:Many of the girls seemed to be infused with excitement on seeing the snow.许多女孩子似乎一看到雪心里就充满了兴奋。Viscous 黏稠的dark, viscous blood....深色且黏稠的血液。Saliva 唾液That saliva was their next study subject. ;And in order to test the saliva we had to get about a fifth of a teaspoon of fluid. Which is a lot of saliva, in a frog#39;s case.;唾液是那些研究课题,为了得到唾液,他们取样了五分之一的茶匙. 对青蛙而言,已经足够了Subject1. 课题,主题2. 受…影响的 (subject to )例:Prices may be subject to alteration.价格可能会受变更影响。Teaspoon 茶匙They put the saliva in a rheometer, a tool that can measure viscosity. And they found that frog saliva is what#39;s called a #39;shear-thinning fluid#39;—its viscosity changes, depending on conditions. ,他们将唾液放在测试粘度的电流计中;他们发现,青蛙的粘液是“剪切稀化液”,也就说粘度会随着环境而改变Rheometer 电流计,血流速度计Shear1. 剪毛例:Competitors have six minutes to shear four sheep.参赛者们有6分钟的时间来给4只羊剪毛。2. 大剪刀例:Trim the shrubs with shears.用大剪刀修剪这些灌木。Thin1. 稀释2. 消磨掉例:War has achieved little, and public patience is wearing thin.战争收获甚微,公众的耐心日渐消磨。You might be more familiar with a different shear-thinning fluid. ;Ketchup. When you smack the bottom of the ketchup bottle you#39;re actually invoking shear forces within the ketchup itself.你可能熟悉其他不同的剪切稀化液“比如番茄酱。当你拍打番茄酱底部的时候,实际上就在唤起番茄酱内部剪力”Ketchup 番茄酱Smack1. 击打例:She smacked me on the side of the head.她打到了我一边脑袋上。2. 带有…迹象; 含有…意味例:The engineers#39; union was unhappy with the motion, saying it smacked of racism.工程师联合会不满意这个提议,说它有种族主义的味道。3. 恰好例:In part that#39;s because industry is smack in the middle of the city.部分是因为工业恰恰就在该市的中心地带。And ketchup, because it#39;s shear thinning, its viscosity actually drops and allows it to slide out of the bottle easily.;由于剪力稀释,所以番茄酱的的粘度实际下降,然后让番茄酱轻松流出来Drop1. 下降2. 放弃例:This was one of the factors that led to President Suharto#39;s dropping of his previous objections.这是导致苏哈托总统放弃他先前反对意见的因素之一。3. 滴; (如酒) 少量例:...a drop of blue ink.…一滴蓝墨水。So back to our frogs: the tongue shoots out, hits the bug and deforms around it. That impact is like a smack on a ketchup bottle—it changes the saliva from thick and sticky to more watery, free to flow all over the bug.回到青蛙上来:舌头射出去,击中虫子,然后使它变形。这种影响力,就像在番茄酱瓶子底部拍打——它改变了从唾液最粘变到不太粘,然后自由将虫子包裹住Bug1. 小虫2. 故障例:There is a bug in the software.软件出了故障Watery1. 微弱的; 淡薄的A watery light began to show through the branches.一缕微弱的光线从树枝间透射过来。2. 含水的; 似水的; 由水组成的例:There was a watery discharge from her ear.她的耳朵里有水状物流出。Then the tongue bounces back, like a bungee cord, and the saliva thickens up again. What#39;s next is beyond weird.然后,舌头像皮筋一样弹回去,唾液再次变厚。接下来更加不可思议Bounce使…弹起; 弹起例:My father would burst into the kitchen bouncing a tennis ball.我父亲会拍打着网球闯进厨房。bungee cord弹力绳Cord 线路,绳子...electrical cord.…电源接线。;Frogs actually take their bulbous eyeballs and bring them down into their mouth cavity and use their eyeballs to shove the insect down the throat.;青蛙实际上要用他们的球状眼睛,然后将他们送入嘴里。然后用眼球将昆虫进入到喉咙里面bulbous圆滚滚的例:his bulbous purple nose....他的紫红色酒糟鼻。Shove猛推例:He shoved her out of the way.他把她推开。That force turns the saliva watery again, ;and the insect slides down the gullet.; The study is in the Journal of the Royal Society Interface.这种力量会使得唾液稀释些,然后昆虫会从滑过食道。这项研究发表皇家社会联系期刊上Turn 变得 (接形容词)例:If the bailiff thinks that things could turn nasty he will enlist the help of the police.如果司法官认为情况可能会变糟,他会寻求警方帮助。gullet食道Interface相互联系; 连接例:...the way we interface with the environment.…我们与环境相互联系的方式。 Article/201705/504813栏目简介:《趣味青春英语视频》是外语网络电台的精品节目,通过大讲堂的网络课堂形式,能够帮助英语学习者积累一些英语背景知识,并通过互动的教学形式,帮助有效记忆英语知识。本栏目是学习趣味青春英语的好材料。 Article/201607/451751There was always a sense of a kind of idian world...that one sees in photographs that were done at the turn of the century, for example, by the Seeberger brothers, or different people who were documenting the bon monde, but it wasn#39;t really street style in that it wasn#39;t, theoretically, ;ordinary; people, going about their business dressed in fascinating ways.总会有那么些场景或照片记录着一个国家的变迁,比如说Seeberger兄弟还有其他这些人的照片见了bon monde,但这些都不算真正意义上的街头潮流理论上的 ;普通人;那些仅仅去做生意,或是什么事情时穿着很棒的人普通人。That really begins to happen in the 1960s, and that is the moment which Bill begins.真正的街头潮流大概开始于二十世纪六十年代Bill大概也是那时开始拍照的。On an Easter Sunday, I came back here to get film, and the phone rang and I picked it up, and it was the Times fashion critic and editorial writer Charlotte Curtis, who I knew very well.有一次的复活节我自己回来洗我的照片忽然接到了一个电话,是《纽约时报》时尚的编辑Charlotte Curtis。And she said, ;Bill, grab your cameras and get up to the Sheep Meadow as quick as you can. They#39;re having a be-in.;她让我马上带着相机去Sheep Meadow她说,;那儿正在举行be-in;。What the hell is a be-in?我完全不知道什么是be-in。I jumped on my bike and went up to the Sheep Meadow, and there were thousands of kids.于是我马上骑车跑到Sheep Meadow那儿有很多很多的年轻人。Oh! I mean, you just never saw anything like it.我从来没见过那样的场景。All the flower children, the hippies, everything,那些带着花儿的孩子,嬉皮士那一切都很新奇。All up there, and it was a lovely day, and they were lying on the grass or the dirt or whatever it was, and they were dressed.那真是有趣的一天他们都打扮的很有趣躺在草地上或是泥地里。It was marvelous, and that really did me in.那真是很奇妙完全吸引住了我。From then on, that was it, kid.从那时起,我开始拍这些年轻人。My Sundays and Saturdays...Saturdays down in SoHo, and Sundays up in the park...were completely taken.我的周末计划有了些改变周六在城里拍照周日跑到这些公园去照。That was it.就是这样。 Article/201608/460207

You couldn#39;t take me to a fine restaurant.I know.你不能带我吃太好的。So you don#39;t care about food? -No.你不在意这儿的食物?-不在意。Really? -Oh, no, no.真的么?-不,真的不在意。Do you listen to music?你听音乐么?I used to go to concerts here, in the churches and the opera.我以前会来这儿的教堂听一些音乐会或是歌剧。But that stopped years ago.There#39;s no time. -Yeah, sure.Right.但是我已经很久都不这样做了。完全没有这个时间。-哦,是的。嗯。I mean, if I#39;m lucky I get to church on Sunday.还好我每周日都去教堂。That#39;s where I hear the music.我就是在那儿听的音乐。Really? You go to church to hear the music?是么?你去教堂听音乐?Do you go to church? -Yeah.你经常去教堂?-是的。Every Sunday? -Yeah.每周日都去?-嗯。Really?真的么?It#39;s no big deal.这没什么…I go and repent.我去教堂忏悔啊。And you see all the paparazzi going crazy? -Oh, yeah.你看那些记者和仔队多疯狂。-哦,是啊。Over Catherine Denueve.他们在追凯瑟琳·德纳芙。I can hear people say, ;He#39;s gotta be the dumbest one in the crowd.He didn#39;t bother photographing her. ;或许有人会说我很愚蠢。我居然不跑过去拍她。Well, she wasn#39;t wearing anything interesting.实话说…她传的一点都不好看。I#39;m interested in clothes.我只对好看的衣感兴趣。And even if I knew them, knew who they were, and usually I don#39;t, I don#39;t go to the movies much and I#39;ve never owned television.很多时候我根本都不知道这些明星是谁,就算我知道他们是谁我也不在意,我很少去看电影我家里都没有电视。 Article/201609/460800

原味人文风情:This is Gudetama. It#39;s an egg yolk with a little butt crack. Gudetama looks like a character someone gave up on—it has limbs but no fingers or toes; it has a mouth but no teeth. And yet, people can#39;t get enough of it. You can find it on backpacks, cups, airplanes, credit cards, and it even has its own theme cafe. But Gudetama#39;s cute looks aren#39;t the driving force behind its insane popularity. Its main attraction is its lazy personality.这是蛋黄哥。它是一颗有一条小股沟的蛋黄。蛋黄哥看起来像一个被人放弃的角色--它有四肢但没有手指或脚趾;它有嘴巴但没有牙齿。然而,人们有再多蛋黄哥都不嫌多。你可以在背包、杯子、飞机、信用卡上看到它的身影,它甚至还有自己的主题咖啡厅。不过蛋黄哥的可爱外貌并不是它爆红的主要因素。它主要吸引人的地方是它软烂的个性。 ;Can I go home now?;「我现在能回家了吗?」;You#39;re the star of the show...;「你是节目的主角耶...」Gudetama comes from a Japanese company called Sanrio. You might have heard of them. They#39;re the creators behind Hello Kitty. In 2013, Sanrio held a company-wide competition to come up with a food-based character. And once people voted, Gudetama didn#39;t end up on top.蛋黄哥出自一家叫三丽鸥的日本公司。你可能听过他们。他们是 Hello Kitty 背后的创造者。2013 年,三丽鸥举办了一场全公司的竞赛来构思出以食物为主的角色。而人们投了票,蛋黄哥最后并未得到第一名。Kirimichan, the salmon fillet, came in first. We actually started to release products based on the salmon fillet and its friends. Gudetama, the lazy egg, came in second, but we also released products based on Gudetama, and it really, really took off.鲑鱼君,一块鲑鱼排,获得首奖。我们真的开始发行以这块鲑鱼排和它的朋友为主的产品。蛋黄哥,一颗懒散的蛋,得到第二名,不过我们也发行了以蛋黄哥为主的产品,而它真的大受欢迎。The appeal of Gudetama#39;s melancholy stands in contrast to the American concept of cuteness, which is pretty straightforward. The idea of cute represents goodness and optimism, while pessimism tends to define evil. This is evident in some of Disney#39;s early films.蛋黄哥的郁闷吸引力和美国对可爱的看法十分不同,美国的可爱还满浅显易懂的。可爱这概念就代表良善和乐观,而悲观往往是邪恶的特性。这在一些迪斯尼早期的电影中显而易见。As you can see, there is a clear divide between good and evil. Villains are usually depicted as unappealing, scary, and old—draped in shadows and dark colors. They#39;re meant to be identified as evil, which means that they can never be cute. But in Japan, there#39;s more of a gray area to this. The word ;kawaii; is widely used to describe the quality of being like a child, which means that you can be cute and lazy at the same time.如你所见,好与坏之间有很清楚的分界。坏人通常被描绘成不迷人、可怕而且衰老的--掩盖在阴影和深色中。他们本该被视为是邪恶的,那也就代表他们永远不可能可爱。不过在日本,这比较有模糊地带。「卡哇伊」一词被广泛用来形容像孩子一样的特性,代表你可以同时又可爱又懒散。Yeah, kawaii is a fascinating idea to me. It#39;s a very vulnerable kind of cute. It#39;s forcing, like... It#39;s you#39;re so cute that you make people wanna take care of you.嗯,卡哇伊对我来说是个很有趣的概念。那是种很脆弱的可爱。那迫使,象是... 就是你可爱到让人想来照顾你。The term emerged in the 1970s and became a big part of Japanese culture. It was shown through fashion, handwriting, and even behavior. And many Japanese artists and academics believed that this popular culture on cuteness happened for a reason.这个词在 1970 年代出现,成为日本文化很重要的一部分。可爱被透过时尚、笔迹,甚至是行为表现出来。而许多日本艺术家和学者相信这种可爱流行文化的出现是有原因的。In Japan, the kawaii culture is often linked to the country#39;s post-World War II years.在日本,可爱文化常被和国家在二战后的那些年作连结。;...a message from the Japanese government. I deem this reply a full acceptance of the Potsdam Declaration.;「...来自日本政府的一则讯息。我将此回覆视为对波兹坦宣言的全然接受。」The idea is that because of its trauma and defeat, the country leaned into its vulnerability. And since then, the concept of kawaii has grown and even formed smaller subgroups.那见解是认为因为日本的的创伤和战败,这国家接受了自身的脆弱。而自那时起,卡哇伊这个概念便开始成长,甚至形成了一些较小的次级团体。This is kimo-kawaii, which is sometimes called ;gro-kawaii.; And there is yuru-kawaii. Yuru means relaxed and calm. According to cartooning expert Aya Kakeda, this particular group became popular because of the stress in modern society. She points out that in the U.S., people are drawn to spas and meditation for relaxation, but in Japan, yuru#39;s calm appearance brings comfort to a lot of people.这是丑萌,有时也被称作「恶心萌」。还有懒萌。Yuru 的意思是放松和平静。根据卡漫专家悬田阿也表示,这个类别变得受欢迎是因为现代社会的压力。她指出在美国,人们喜欢用 spa 疗程和冥想来放松,但在日本,懒萌角色的平和外表疗愈了许多人。You can also see a shift in Sanrio#39;s characters throughout the years. They#39;ve started giving them a personality to make them more relatable. When Hello Kitty came out in 1974, she was more traditionally cute than Gudetama, but she remained somewhat emotionless. She doesn#39;t even have a mouth to smile or frown with, and that makes her more of a blank canvas—she can be whatever we want her to be. But many people feel a connection with Gudetama because of its gloomy personality. This approach to cuteness extends beyond appearances. It evokes a reaction. These characters can make you laugh or feel relaxed, and you can relate to them by observing their personality.你也可以看到三丽鸥的角色在这些年来的变化。他们开始赋予角色个性来让它们更亲切。当 Hello Kitty 在 1974 年问世时,她相较于蛋黄哥是种比较传统的可爱,不过她有一点没有感情。她甚至没有嘴巴来微笑或表示不满,那使得 Hello Kitty 比较像张空白画布--她可以变成我们想要的任何样子。不过很多人因为蛋黄哥忧郁的个性而感到和它有种连结。这种对可爱的诠释超越了外表。那激发出一种反应。这些角色能让你开怀笑或感到放松,而你可以透过观察他们的个性来产生共鸣。So at a time of confusion and turmoil all around the world, maybe this is just what we need—an egg yolk with a little bum that#39;s just done dealing with life.所以在一个到处充满困惑和动荡的时代,或许这就是我们所需要的--一颗有着小屁股的厌世蛋黄。;Can#39;t see the future.;「看不到未来。」;Today might be a better day.;「今天或许会是更美好的一天。」 Article/201706/513261
