双语阅读 | 珠穆朗玛峰新身高

珠穆朗玛峰新身高The New Height of Mount Qomolangma林晓洁 供稿The height of Mount Qomolangma is one of the most fascinating questionsin geography. Every time its measurement makes a splashacross the world. On December 8th,2020, ChinaandNepalagreed on a new official height forMount Qomolangma, ending a long-running dispute over the exact height of the world’s tallest mountain.珠穆拉玛峰的确切高度是地理学上最引人入胜的问题之一,每次它的高度测定都会在全世界引起轰动。2020年12月8日,中国和尼泊尔就珠穆朗玛峰新的官方高度达成一致,结束了关于世界最高峰确切高度的长期争议。The mountain is officially 8,848.86 meters, according to the number agreed upon by both countries. That’s 86 centimeters higher than the measurement made by the Survey of India in 1954, which has been the widely accepted number ever since.Since then, there have been a bunch of other surveys which found slightly different measurements.根据两国一致确定的数字,珠穆拉玛峰的官方海拔为8848.86米。这一数字比1954年由印度测绘局测得并在之后得到世界广泛认可的数字高出86厘米。从那以后,多次测量的结果出现了一些细微不同。So how to measure a mountain?那么如何测量一座山的高度呢?The main technique that's been used for hundreds of years is trigonometry, to be precise.Surveyors measure two points on the ground and from each point they measure the angle between them and the top of the mountain to give them a triangle. Using those triangles and the laws of trigonometry, they can calculate the height of the mountain.准确地说,三角学是测量山峰中运用的主要方法,这一方法已被使用了数百年。测量员在地面上测量两个点,从每个点测量它们与山顶之间的夹角,从而得到一个三角形。利用三角定律,测量员便能计算出山峰的高度。The first person to measure Mount Qomolangmausing that method was George Everestback in 1856. To get the angles, he had to use theodolites, which weighed about 500 kilos. As a result, the Great Trigonometric Survey of British India has peggedthe mountain, known to them as Peak XVand later named afterSir George Everest, at 29,002 feet. 首次利用这种方法测量珠穆朗玛峰的人是1856年的乔治·额菲尔士。为了测得三角形夹角,他不得不使用重达500公斤的经纬仪进行测量。利用大三角测量法,英属印度测量局测得珠穆拉玛峰的海拔为29002英尺。当时他们将珠峰称为“第十五峰”,而后又以额菲尔士爵士的名字重新命名该山。Fast forward to the 1950s, and surveyors got a bit of help from photogrammetry, detailed photos taken from the air that they could use to measure heights and distances.到了20世纪50年代,测量员们从摄影测量学中得到启发,利用从空中拍摄的高清照片来测量山峰的高度和距离。 Now peoplehave even fancier technology to measure mountains--the Global Positioning System or GPS. Surveyors can bring a GPS receiver to the top of the mountain, where satellites in space can pick up their location and work out the height, again, using triangles.如今,人们利用更先进的技术来测量山峰——全球定位系统(GPS)。测量员将GPS接收器带至山顶,太空中的卫星可以接收到它们的位置,计算出山峰高度。异曲同工的是,该方法也是利用三角形原理。The 1954 measurement included the mountain’s snow-cap, but China came up with a shorter measurement in 2005, when it excluded the cap. In 2020, Chinaand Nepalfinally agreed to re-measure the mountain from the top to the mean sea level, using GPS and the latest surveying equipment. They spent two years training a team for the project, then placed several markers around the mountain and another at the very top to come up with the new number.1954年的测量包括了珠峰雪顶部分的高度,但中国在2005年提出了一种更精简的测量方法,能减去雪顶部分的高度。2020年,中国和尼泊尔同意使用GPS和最新的测量设备重新测量珠峰从山顶到平均海平面的高度。为此,双方耗时两年培训测量团队,并在珠峰四周和山顶分别进行标记,从而测得新的数字。There's debate over whether you should count the snow on top, or just the rock underneath.And there's a possibility that the height has actually changed because of erosion and earthquakes.In fact, scientists reckon this earthquake in Nepal in 2015 might have knocked some height off this very high mountain. 关于是否应该计入山顶的积雪厚度,或是仅仅计算以下岩石部分的高度,还没有最终的定论。同时,侵蚀和地震也是导致珠峰高度发生变化的可能原因。事实上,科学家们认为,2015年发生的尼泊尔地震可能导致了世界最高峰的高度有所下降。With no climbers around due tothe pandemic, scientists regarded it the perfecttime for a re-measure. Theteamof surveyors that worked out the new height of the mountain is the first andthe only group to summit Qomolangmain 2020.Let’s remember the height of the world’s highest mountain –8848.86 meters.由于疫情的到来,珠峰的攀登者变得寥寥,这为珠峰高度的测量提供了独特的契机。此次测出珠峰新高度的测量队是2020年首支也是唯一一支成功登顶珠峰的队伍。让我们记住世界最高峰的高度——8848.86米吧!【VOCABULARY】1.make a splash引起轰动2.trigonometryn. 三角学3.theodoliten. 经纬仪4.pegv.使尺度、价格等固定于某水平5.photogrammetryn. 照相测量法

双语阅读 | 改变飞行高度可减少影响气候的飞机云

改变飞行高度可减少影响气候的飞机云Changing the altitude of flightsdecreases contrails that affect the weather林晓洁供稿Airplanes account for about 3 percent of the climate-altering carbondioxide emissions we add to the atmosphere. But planes are warming the planet in another way. “So if you look up inthe sky, you probably see, at some point, an aircraft. And behind that aircraft are white, fluffystreaks. And that’s what we call a contrail.” said Imperial College London engineer Marc Stettler.人类排放到大气中的二氧化碳正改变着气候,其中3%的碳排放来源于飞机。然而,飞机还正以另一种方式加剧全球变暖。伦敦帝国理工学院的工程师马克·斯泰特勒介绍:“当你仰望天空时,某个时刻可能会看到飞机。飞机后面拖着几条毛绒绒的白色拉线,我们称之为飞机云。”Contrails are made up of ice crystals that form when aircraft enginesemitexhaustthat hits the cold air. The ice crystals reflect incoming light from the sun back into space, which has a cooling effect on theatmosphere.But the contrails also stop heat coming up from the ground fromescaping into space. “It’s reflected back down toward the ground. And so that’s a warming effect.”飞机云由冰晶组成,而这些冰晶则是由飞机引擎排放的废气遇冷空气凝结而成。冰晶将太阳的入射光反射回太空,对大气产生冷却效应。但飞机云也阻止了地面热量逃逸到太空中。“热量被反射回地面。因此这是种升温效应。”Stettler says, on balance, contrailswarm the atmosphere more than they cool it. “And that’s primarily because the cooling effect due to reflecting of sunlight can only happen during the day, when the sun’s shining, whereas the warming effect due to trapping of outgoing heat happens all of the time.”斯泰特勒表示,总的来说,飞机云对大气的升温作用大于冷却作用。“主要是因为反射太阳光所产生的冷却效应只能在白天有太阳时产生,而由于阻挡散发热量所产生的升温效应则全天都在发生。”Some contrailscan form clouds that last for up to 18 hours. During that time, they spread out, trapping even more heat. This process allows contrails to warm the planet about as much as the carbon dioxide emissions from aircraft. 有些飞机云可以形成持续18小时不散的云团。在这段时间里,这些云团扩散开来,阻挡了更多热量的散发。这一过程使飞机云给地球带来的升温效应与飞机排放的二氧化碳基本持平。But when Stettler and his team analyzed flight data they obtained ofJapan airspace, they found that most contrail warming was caused by just 2 percent of flights. And most of those flights originatedin the late afternoon because as the sun goes down, cooling can no longer offset the warming. “And thewarming effect persists throughout the evening, into the night.” But what if the contrails that contribute the most to warming could be eliminated? Such a change could be achieved if aircraft avoided flying in the thin layers of humiditywhere contrails form.然而,当斯泰特勒及其团队分析从日本领空获得的飞行数据时,他们发现飞机云产生的大部分升温效应仅由2%的航班造成。这些航班大多在傍晚起飞,随着太阳下山,飞机云的冷却作用无法抵消其升温作用。“升温效应从傍晚一直持续到深夜。”那如果对升温作用最明显的飞机云可以被消除呢?只要飞机避免在形成飞机云的潮湿薄层大气中飞行,就可以实现这一改变。“By changing the altitude only by couple of thousand feet, either up or down, it would no longer form contrail. And so what we found in this study was that by changing the altitude of less than 2 percent of flights, we could actually get rid of just under 60 percent of the warming effect due to contrails.” The study is in the journal Environmental Science &Technology.“将飞行高度提升或降低几千英尺,就不会再形成飞机云。因此,我们在这项研究中发现,改变不到2%的航班的飞行高度就可以消除接近60%由飞机云引起的升温效应。”这项研究发表在《环境科学与技术》期刊上。This improved understanding of how to manage contrails presents an opportunity for the aviation industry to reduce its global environmental impact. Think of it as a silver liningin those contrail clouds.这一研究使我们加深了认识,了解到如何更好地控制飞机云的形成,也为航空业减少其对全球气候的影响提供了机遇。正如乌云周边都有一线光亮,我们也可以把这项成果视作是解决飞机云问题的一丝希望吧!【VOCABULARY】1.fluffyn.毛绒绒的;松软的;蓬松的2.emit v.排放;排出3.exhaust n.废气;排放物4.contrails n.飞机云;凝结尾(飞机飞过留下的尾迹)5.originatev.起驶;起航6.humidityn.湿度;湿气(图片来源摄图网,版权归摄图网享有)

Subway Etiquette:Please Wear Headphones If You're Listening To Music地铁礼仪:乘坐地铁听音乐请佩戴耳机王淑怡 供稿You can often have a feeling of dread on a crowded subway car or when the doors open with a fresh batch of people crammingin. But that's not the worst. Imagine heading to work barely awake at 6 a.m. or getting off after a long day at the office and being subjected to loud music, videos, games and streamingshows that have no meaning to you. They are the last things you want to hear.在拥挤的地铁车厢内,或者当车门开启人流涌入,你常常会产生一种恐惧感,但这还不是最糟糕的。想象一下,早上6点起床去上班,或是结束了一整天的工作之后,在上下班的途中,耳朵里却充斥着对你来说毫无意义的音乐、视频、游戏和直播节目。这恐怕是你最不想听到的。After receiving loads ofcomplaints about noise on the subway, the city of Shanghai banned subway riders from using speakerson their electronic devices, including mobile phones. So far, Shanghai, Beijing, Tianjin, Wuhan and Kunming have all banned noise on subway cars.针对地铁上电子设备声音外放一事,有关部门已经收到了大量的市民投诉。为此,上海市出台了一项新规,明确禁止地铁乘客在使用手机等电子设备时外放声音。目前,上海、北京、天津、武汉、昆明等地都已禁止在轨道交通内外放声音。When it comes to subway etiquette,the worst offense is when people use their devices as speakers."It really grindsmy gearswhen someone playsthemusiconTik Tok, Kuaishou, etc. without putting on any headphones," a passenger grumbled.谈及地铁礼仪,恐怕最令人厌烦的就是乘坐地铁时使用手机外放声音。一名乘客抱怨道:“总有乘客旁若无人地用手机外放抖音、快手上的神曲。真是烦不胜烦!”An inspector of Shanghai rail transport said subway workers would first try to persuade riders using noisy devices to stop; if it fails,thenthe officers will refer the matter to the public security department. Other passengers are welcome to report breaches.上海轨道交通的一名检查人员表示,一旦发现手机外放的行为,地铁工作人员会首先进行劝阻。实在不听劝阻的,将送交公安处理。此外,乘客发现不文明行为,也可以进行举报。The new regulation has sparked heated discussion amongnetizenson Chinese social media platform Sina Weibo. Many residents welcome the new rule,but they also doubt whether this new regulation will be put into effect. AccordingtoSun Jianping, Director of the Urban Risk Management Research Institute at Tongji University, since the "man-made noise" in the subway has long been a headache, such a new regulation may help create a better transport environment. However,creating a better transport environment requires joint efforts from all parties, not only supervision by law enforcement personnel but also self-disciplineby passengers. 这项新规定在中国的社交媒体平台新浪微博上引发了网民的热烈讨论。多数市民为这项新规的实施拍手叫好,但也对规定能否真正落地表示怀疑。同济大学城市风险管理研究院院长孙建平表示,外放声音等车厢陋习长期以来都是一个痛点,这项新规的出台有助于打造更舒适的乘车环境。但是,这需要各方的共同努力,除了加强执法部门的监管外,更需要全民提高文明素质。【VOCABULARY】1.etiquetten.(社会或行业中的)礼节;礼仪;规矩2.cramv.把…塞进;挤满;塞满3.streamingn.串流传播(流媒体)4.loads of许多;大量5.speakern.扬声器6.grindv.磨碎;碾碎;把…磨成粉7.gearn.排挡;齿轮;传动装置8.Tik Tok抖音短视频应用9.breachn.

VOA慢速:2020年印度经济陷入严重衰退燕山大学 刘立军 供稿【TRANSCRIPT】The year 2020 brought India its most serious economic and security issues in many years. The COVID-19 pandemic pushed the country into a recession.India ordered one of the world's most severe lockdowns in March, when it had just a few hundred coronavirus cases. But when the country started opening up, the virus began to spread quickly. By the end of the year, India was the second-worst hit nation, with nearly 10 million COVID-19 cases.Millions of people lost jobs and hundreds of small businesses closed. But experts warned that the economic problems went deeper than the health crisis.The first evidence of this came in April when India witnessed a never-before-seen exodusof migrant laborers. Having lost jobs in cities, millions walked hundreds of kilometers to their villages when all transport was halted.India has been the worst hit among large economies because nearly 90 percent of its workers survive on its informal sector. The economy is expected to fall by nine percent this year, its worst recession in 40 years.The Center for Monitoring Indian Economy estimated that about 120 million jobs were lost from April to June. Many jobs came back as the government began easing lockdowns to help. But millions of people are still struggling to find work.Among the jobless are tens of thousands of street sellers whose businesses were destroyed by the pandemic.Ranga Shalivan restarted his two small roadside food stands in July in the city of Hyderabad. For months, few people bought his food. But he has seen some improvement in recent weeks.It's a little better now, "but I am still making only about half the money that I used to. It has been very hard," he said.The government has announced two stimulusbills. But Finance Minister Nirmala Sitharaman told industry leaders it would not be enough to deal with the crisis caused by the pandemic.Now at the end of the year, there is hope that the worst may be over as India gets control of the health crisis. Numbers of new COVID-19 infections are lessening. And a new vaccine is expected to come within weeks.Economist Arun Kumar, however, has warned that real progress will be a long-term process for the world's second most populouscountry.During the past year, Prime Minister Narendra Modi also faced some of his biggest challenges since taking power six years ago. There was widespread protest over a new citizenship law that critics say discriminates against Muslims. In the Indian capital in February, communal riotskilled more than 50 people. Then in December, tens of thousands of farmers camped on the edges of New Delhi, angered by new farming laws. They worry the laws will open them to corporate abuse.Experts say while the pandemic tested nations worldwide, India's challenges could make the road to recovery longer and harder.I'm Alice Bryant.Adapted from http://www.kekenet.com/broadcast/202101/622981.shtml【VOCABULARY】1.recessionn. a difficult time for the economy of a country, when there is less trade and industrial activity than usual and more people are unemployed 经济衰退;经济萎缩。例如:The economy is in deep recession. 经济正处于严重的衰退之中。2.exodusn.(formal, or humorous) a situation in which many people leave a place at the same time (大批人同时)离开;外出;出去。例如:the mass exodus from Paris to the country in the summer夏日大批人从巴黎外出到乡村3.halt v.to stop; to make sb. / sth. stop (使)停止;停下4.stimulus n.something that helps sb. /sth. to develop better or more quickly 促进因素;激励因素;刺激物。例如:The new tax laws should act as a stimulus to exports. 新税法应该能促进出口。5.populous adj.(formal) where a large number of people live 人口众多的;人口密集的。例如:one of America's most populous states美国的人口大州之一6. riot n.a situation in which a group of people behave in a violent way in a public place, often as a protest 暴乱;骚乱【QUESTIONS】Read the statements.

BBC新闻:英国开始适应脱欧后的生活燕山大学 刘立军 供稿【TRANSCRIPT】Hello, I'm Debbie Russ with the BBC News. Customs checks are being stepped up on goods crossing the channel between Britain and France for the first time in decades as Britain adjusts to life outside the European Union. The British Prime Minister Boris Johnson said the UK now had freedom in its hands. Jessica Parker reports. Last night, following decades of membership, years of debate and points of political turmoil, the time came. While the UK left the EU last January, it was yesterday evening that the transition period ended, and largely brought that departure into effect. Boris Johnson described it as an amazing moment for the country. It is one that some will regard with huge optimism, others, with deep regret.Portugal has taken over the rotating presidency of the European Union with the main focus expected to be the block's recovery from the pandemic. During its 6 month term, Portugal must oversee the validation of member states' plans to use their share of the blocks recovery fund worth $900 billion.Sudan's acting Foreign Minister Omer Ismail has told the BBC that his country's army has changed and will protect civiliansin Darfur despite fears voiced by local people. Mr. Ismail said he understood the concerns based on the actions of the previous government, but that the situation was now different. “We give the guarantees that this army had changed, and it is going to protect them. Besides, the fact that it's a joint effort within the army and the new police and many other agencies are involved in this.” Mr. Ismail was speaking after the Sudanese army took over security in the region after a 13-year United Nations and African Union peacekeeping mission came to an end. Sudan's oustedPresident Omar al-Bashir is accused of committing atrocitiesin Darfur.The countries of the Americas have been the latest to see in the new year in a subduedfashion because of the pandemic. Paul Hawkins has the details. No crowds and no parties, the New Year's Eve theme for many, including New York, where Time Square was closed to the public, and Rio's famous New Year's Eve beach party on Copacabana was cancelled. In London, the message, stay at home. While in Scotland, they opted for synchronizedHogmanay drones instead of fireworks. France had music master Jean-Michel Jarre live from his studio playing in a virtual Notre Dame cathedral, but the reality was somewhat different with an empty Paris, like much of Europe.
