The study found the Australian bushfires two years ago were so intense that smoke rose into the atmosphere, causing a complex set of chemical reactions that led to the loss of ozone in the layer that protects the Earth from damaging ultraviolet rays.
这项研究发现，两年前的澳大利亚林火非常猛烈，以至于烟雾上升到了大气层，造成一系列复杂的化学反应，导致臭氧的损失，臭氧层是大气中保护地球免受紫外线破坏的气层。
Satellite observations suggest a total ozone loss of 1% over the southern hemisphere within the month of March 2020 alone. Not insignificant, given the slow recovery of the ozone layer from damage caused decades ago.
卫星观测表明，仅在2020年3月，南半球上空就一共损失了1%的臭氧。鉴于臭氧层几十年前受到破坏后，恢复缓慢，这一数字不容忽视。

One side of the planet probably always faces its star. Four other planets, all gas giants, are known to orbit the same star. The planet is found in our Milky Way galaxy, about 41 light-years from Earth. A light-year is the distance light travels in a year, or 9.5 trillion kilometers.
行星的一侧可能总是面向其恒星。 已知还有另外四颗行星，都是气态巨行星，绕着同一颗恒星运行。 这颗行星位于我们的银河系中，距地球约 41 光年。 一光年是光一年传播的距离，即 9.5 万亿公里。
The planet’s star is gravitationally tied to another star in the system. Having two stars in the same system is called a binary system.
该行星的恒星通过引力与系统中的另一颗恒星相连。 同一系统中有两颗恒星称为双星系统。
The other star is a red dwarf, the smallest kind of an ordinary star. The distance between these two stars is 1,000 times the distance between Earth and the sun. Light from one star takes six days to reach the other star.
另一颗恒星是红矮星，是最小的普通恒星。 这两颗恒星之间的距离是地球与太阳之间距离的1000倍。 来自一颗恒星的光需要六天才能到达另一颗恒星。
Although the rocky planet does appear to have an atmosphere, scientists say it probably should not even have one. Being so close to its star, any atmosphere should be taken away by the effects of the star.
尽管这颗岩石行星似乎确实有大气层，但科学家表示它可能根本不应该有大气层。 由于距离恒星如此之近，任何大气层都会受到恒星的影响而消失。
But gases dissolved in the planet’s large ocean of molten rock may continue to fill up the atmosphere, Hu said.
但胡说，溶解在地球上巨大的熔岩海洋中的气体可能会继续充满大气层。
“The planet cannot be habitable,” Hu added. That is because it is too hot to have liquid water, which is also considered necessary for life.
“这个星球不适合居住，”胡补充道。 这是因为太热了，无法拥有液态水，而液态水也被认为是生命所必需的。
Scientists have found other planets with an atmosphere outside our solar system. But they have all been gaseous planets, not rocky ones.
科学家们在太阳系之外发现了其他拥有大气层的行星。 但它们都是气态行星，而不是岩石行星。
As the James Webb telescope pushes the limits of space exploration, the discovery of a rocky planet with an atmosphere is a sign of progress.
随着詹姆斯·韦伯望远镜突破了太空探索的极限，发现具有大气层的岩石行星是进步的标志。
On Earth, the atmosphere warms the planet. It contains the oxygen people breathe and protects against the effects of the sun. It also creates the pressure needed for liquid water to remain on the planet’s surface.
在地球上，大气层使地球变暖。 它含有人们呼吸的氧气并防止阳光的影响。 它还产生液态水留在地球表面所需的压力。
Brice-Olivier Demory is a scientist at Switzerland’s University of Bern’s Center for Space and Habitability. He helped write the new study. He said, “On Earth, atmosphere is key for life.” He added that the findings create hope that the Webb telescope may one day find cooler planets that could support liquid water on their surface.
布里斯-奥利维耶·德莫里 (Brice-Olivier Demory) 是瑞士伯尔尼大学空间与宜居中心的科学家。 他帮助撰写了这项新研究。 他说：“在地球上，大气是生命的关键。” 他补充说，这些发现带来了希望，韦伯望远镜有一天可能会发现能够在其表面支持液态水的较冷行星。
“But,” he said, “we are not there yet.”
“但是，”他说，“我们还没有到那一步。”

Astronomers have searched for years for rocky planets outside our solar system. They have finally found one with an atmosphere.
天文学家多年来一直在太阳系外寻找岩石行星。 他们终于找到了一个有气氛的人。
Scientists believe that a rocky planet with an atmosphere is key to sustaining life. But the planet that astronomers found offers no hope for life. Its surface is made up of molten rock.
科学家认为，具有大气层的岩石行星是维持生命的关键。 但天文学家发现的这颗行星没有生命存在的希望。 它的表面由熔岩组成。
Researchers recently called the planet a “super-Earth.” It is a rocky world much larger than our planet but smaller than the gas giant in our solar system, Neptune.
研究人员最近称这颗行星为“超级地球”。 这是一个岩石世界，比我们的星球大得多，但比太阳系中的气态巨行星海王星小。
The planet orbits extremely close to its star. The star is less bright and smaller than our own.
这颗行星的轨道非常靠近其恒星。 这颗恒星比我们的恒星更暗、更小。
Observations using two devices aboard the James Webb Space Telescope suggest there is an atmosphere. But the atmosphere may not be able to support life. It could be continuously filled up by gases that large areas of molten rock release.
使用詹姆斯·韦伯太空望远镜上的两个设备进行的观测表明存在大气层。 但大气层可能无法维持生命。 它可以不断地被大面积熔岩释放的气体充满。
Renyu Hu is a planetary scientist with NASA’s Jet Propulsion Laboratory and California Institute of Technology. He was the lead writer of the study, which appeared recently in the publication Nature.
胡仁宇是美国宇航局喷气推进实验室和加州理工学院的行星科学家。 他是这项研究的主要作者，该研究最近发表在《自然》杂志上。
Hu said, “The atmosphere is likely rich in carbon dioxide or carbon monoxide, but can also have other gases such as water vapor and sulfur dioxide.” He added that current observations cannot tell what the exact atmospheric makeup is.
胡说：“大气中可能富含二氧化碳或一氧化碳，但也可能含有其他气体，例如水蒸气和二氧化硫。” 他补充说，目前的观测无法告诉我们确切的大气成分是什么。
The Webb data also did not make clear the thickness of the atmosphere. Hu said it could be as thick as Earth’s or even thicker than that of Venus. Venus has a toxic atmosphere that is the densest in our solar system.
韦伯数据也没有明确大气层的厚度。 胡说，它的厚度可能与地球一样厚，甚至比金星还要厚。 金星的有毒大气层是太阳系中最稠密的。
The planet is called 55 Cancri e. Scientists also call it Janssen. It is about 8.8 times more massive than Earth and about two times as wide.
这颗行星被称为 55 Cancri e。 科学家也称其为詹森。 它的质量约为地球的 8.8 倍，宽度约为地球的两倍。
It orbits its star at one-25th the distance between our solar system’s innermost planet Mercury and the sun. As a result, its surface temperature is about 1,725 degrees Celsius.
它绕恒星运行的距离是太阳系最内层行星水星与太阳之间距离的二十五分之一。 因此，其表面温度约为1725摄氏度。

A Japanese town hopes to keep out crowds of visitors by building a large barrier to block views of the country’s tallest mountain, Mount Fuji.
日本的一个小镇希望通过建造一个巨大的屏障来阻挡大批游客，以阻挡该国最高峰富士山的景色。
The town is called Fujikawaguchiko. It sits on Japan’s main island of Honshu, southwest of Tokyo. The community is known for having good spots for taking pictures of Mount Fuji.
这个小镇叫做富士河口湖。 它位于东京西南部的日本主岛本州岛。 该社区以拍摄富士山的好地点而闻名。
But some locals and business owners feel there are too many misbehaving tourists. In an effort to reduce the number of visitors, city workers have started building a large black screen to block views of Mount Fuji.
但一些当地人和企业主认为，行为不端的游客太多了。 为了减少游客数量，城市工作人员开始建造一个巨大的黑屏来遮挡富士山的景色。
Michie Motomochi owns a restaurant that serves Japanese sweets near the soon-to-be-blocked photo spot. She told The Associated Press that while she welcomes visitors to the area, “there are many things about their manners that are worrying.”
Michie Motomochi 在即将被封锁的拍照点附近拥有一家供应日式甜点的餐厅。 她告诉美联社，虽然她欢迎游客来到该地区，但“他们的举止有很多令人担忧的地方。”
Motomochi said she has seen visitors crossing the road in busy traffic, leaving waste on streets, ignoring stop lights and trespassing onto private property.
元持说，她看到游客在繁忙的交通中过马路，在街道上留下垃圾，无视红绿灯，并侵入私人财产。
She noted, however, that about 80 percent of her business is driven by foreign visitors. Tourist numbers have been rising in Japan since restrictions were lifted after the COVID-19 pandemic.
然而她指出，她约 80% 的业务是由外国游客推动的。 自 COVID-19 大流行后取消限制以来，日本的游客人数一直在增加。
Motomochi said her neighborhood suddenly became a popular spot for visitors about two years ago. That is when a photo taken in the area went viral on the internet. The photo showed Mount Fuji in the background. But it appeared as though the mountain was sitting on top of a local store called Lawson.
本持说，大约两年前，她的社区突然成为游客的热门景点。 就在那时，一张在该地区拍摄的照片在互联网上疯传。 照片的背景是富士山。 但这座山似乎坐落在当地一家名为劳森的商店的顶部。
Town officials say the photo was widely shared on social media and became known online as “Mt. Fuji Lawson.” Since then, foreign tourists have crowded the neighborhood.
镇官员表示，这张照片在社交媒体上广泛传播，并在网上被称为“山”。 富士劳森。” 从那时起，外国游客就挤满了附近。
The town has tried other methods to limit bad behaviors by tourists. The town put up signs in several languages urging visitors not to run into the road. It has provided information about crosswalks. And it even hired security guards
该镇尝试了其他方法来限制游客的不良行为。 镇上竖起了多种语言的标牌，敦促游客不要跑到马路上。 它提供了有关人行横道的信息。 甚至还聘请了保安
The black screen is expected to be completed in the middle of May. It will stand 2.5 meters high and 20 meters long. Officials say the barrier will almost completely block the view of Mount Fuji.
黑屏预计5月中旬完成。 它将高 2.5 米，长 20 米。 官员称，该屏障将几乎完全挡住富士山的视线。
French tourist Anthony Hok told the AP he thinks the screen was an overreaction by city officials. He said the solution seemed “too big” for the problem the town was facing. The 26-year-old visitor suggested setting up road barriers for safety instead of blocking views for pictures.
法国游客安东尼·霍克告诉美联社，他认为该屏幕是市政府官员反应过度。 他说，这个解决方案对于该镇面临的问题来说似乎“太大了”。 这位26岁的游客建议为了安全而设置路障，而不是挡住拍照的视线。
But Helen Pull, a 34-year-old visitor from Britain, said she understood the local concerns. She said she had seen tourism “really ramped up” in the country. “I can see why people who live and work here might want to do something about that," Pull added.
但来自英国的 34 岁游客海伦·普尔 (Helen Pull) 表示，她理解当地人的担忧。 她说她看到该国的旅游业“真正蓬勃发展”。 “我可以理解为什么在这里生活和工作的人们可能想为此做点什么，”拉补充道。
Yoshihiko Ogawa runs an old rice shop in the Fujikawaguchiko area. He said overcrowding there had worsened in recent months, with tourists gathering from around 4 or 5 in the morning and talking loudly. Ogawa said crowds in the area also sometimes block his car.
小川义彦在富士河口湖地区经营一家老米店。 他说，近几个月来，那里的拥挤状况进一步恶化，游客从凌晨四五点左右就开始聚集并大声交谈。 小川说，该地区的人群有时也会堵塞他的车。
“We’ve never thought we'd face a situation like this,” Ogawa told the AP. But he added that he was unsure what the right solution might be. “I suppose we all just need to get used to it,” he said.
“我们从未想过会面临这样的情况，”小川告诉美联社。 但他补充说，他不确定正确的解决方案是什么。 “我想我们都需要习惯它，”他说。

An American country music star has used artificial intelligence to make music again, years after suffering a stroke.
一位美国乡村音乐明星在中风多年后再次使用人工智能创作音乐。
Randy Travis is 65 years old. He was a popular country music performer in the 1980s and 1990s and won several Grammy awards during his career. But in 2013, he went to the hospital with a heart problem and later had a stroke. The stroke made it hard for Travis to speak. He has not made music since his stroke – until now.
兰迪·特拉维斯今年 65 岁。 他是20世纪80年代和90年代流行的乡村音乐表演者，在他的职业生涯中多次获得格莱美奖。 但2013年，他因心脏病入院，后来中风。 中风使特拉维斯说话变得困难。 自从中风以来，他一直没有创作音乐，直到现在。
On May 3, Travis released a new song with the help of artificial intelligence, or AI. It is called Where That Came From. Nashville, Tennessee songwriters Scotty Emerick and John Scott Sherrill wrote the song.
5月3日，Travis 在人工智能（AI）的帮助下发布了一首新歌。 它的名字叫《从哪里来》。 田纳西州纳什维尔的词曲作者斯科蒂·埃默里克和约翰·斯科特·谢里尔创作了这首歌。
Cris Lacy is co-president of Warner Music Nashville, the company that produces Travis’ music. Lacy said she contacted Travis’ wife Mary and asked “What if we could take Randy’s voice and recreate it using AI?”
克里斯·莱西 (Cris Lacy) 是纳什维尔华纳音乐公司 (Warner Music Nashville) 的联合总裁，该公司为特拉维斯 (Travis) 制作音乐。 莱西说，她联系了特拉维斯的妻子玛丽并询问“如果我们可以采用兰迪的声音并使用人工智能重新创建它怎么办？”
“We were all over that, so we were so excited,” Mary Travis said about the chance to hear her husband’s voice in a new song. “All I ever wanted since the day of the stroke was to hear that voice again.”
“我们都沉浸在这一切之中，所以我们非常兴奋，”玛丽·特拉维斯谈到有机会在一首新歌中听到她丈夫的声音时说道。 “自从中风那天起，我唯一想要的就是再次听到那个声音。”
Lacy talked with computer programmers in London about making an AI system that could recreate Travis’ voice. They produced two models. One model used 12 vocal samples from Travis’ career and the other used 42 samples. There was a lot of material to work with; the singer’s first big record, Storms of Life, came out in 1985.
莱西与伦敦的计算机程序员讨论了如何制作一个可以重现特拉维斯声音的人工智能系统。 他们生产了两种型号。 一个模型使用了 Travis 职业生涯中的 12 个声音样本，另一个模型使用了 42 个样本。 有很多材料可供使用； 这位歌手的第一张大唱片《Storms of Life》于 1985 年发行。
Travis’ long-time music producer is Kyle Lehning. He said Where That Came From was a song that fit Travis’ way of singing. When Travis was at the top of his career, he was known for a more traditional kind of country music. It was a contrast to the pop-country songs that were popular in the late 1980s.
特拉维斯的长期音乐制作人是凯尔·莱宁。 他说《Where That Came From》是一首适合特拉维斯演唱方式的歌曲。 当特拉维斯（Travis）处于职业生涯的巅峰时，他以更传统的乡村音乐而闻名。 这与 20 世纪 80 年代末流行的流行乡村歌曲形成鲜明对比。
Lehning talked about the process of making the song. First, another singer recorded the song in what is known as a “demo.” Then the AI system analyzed the song and applied Travis’ voice to it.
莱宁谈到了这首歌的制作过程。 首先，另一位歌手以所谓的“演示”形式录制了这首歌。 然后人工智能系统分析了这首歌并将特拉维斯的声音应用到其中。
“I really wish somebody had been here with a camera,” Lehning said about the experience of watching the computer apply Travis’ voice to the song. “And it was stunning, to me, how good it was … right off the bat.”
“我真的希望有人带着相机来到这里，”莱宁谈到观看电脑将特拉维斯的声音应用到歌曲中的经历时说道。 “对我来说，这真是太棒了……立刻就变得多么好。”
Lehning said some parts of the sound created by the computer were “not authentic to Randy’s performance.” Lehning worked with Casey Wood, a recording engineer who knew Travis well, to get it right.
莱宁表示，计算机产生的声音的某些部分“与兰迪的表演并不真实”。 莱宁与熟悉特拉维斯的录音工程师凯西·伍德合作，以确保其正确。
The two music professionals used sound parts from both vocal models. They made changes to the speed of some of the sounds. Lehning said Travis is “a laid-back singer,” so they had to slow down some parts. They wanted to keep an “old soul quality” in Travis’ voice.
两位音乐专业人士使用了两位声乐模型的声音部分。 他们改变了一些声音的速度。 莱宁说特拉维斯是“一位悠闲的歌手”，所以他们不得不放慢一些部分的速度。 他们希望特拉维斯的声音保持“古老的灵魂品质”。
Lehning said they were able to improve on the AI version. And Mary Travis said the final version of her husband’s song is much different than what happens when a computer programmer uses AI to create something without permission.
Lehning 表示他们能够改进人工智能版本。 玛丽·特拉维斯 (Mary Travis) 表示，她丈夫歌曲的最终版本与计算机程序员未经许可使用人工智能创建某些东西时发生的情况有很大不同。
She called the producers’ and engineers’ work on the project “the human element.”
她将该项目的制作人和工程师的工作称为“人的因素”。
She added that her husband had a thoughtful look on his face when he first heard the song. “I think he went through every emotion there was in those three minutes of just hearing his voice again,” Mary Travis said.
她补充说，当她丈夫第一次听到这首歌时，脸上露出若有所思的表情。 “我认为，在再次听到他的声音的那三分钟里，他经历了所有的情绪，”玛丽·特拉维斯说。

Venice is a fragile jewel faced with rising sea levels from climate change and mass tourism. Of the estimated 30 million visitors a year, around two thirds are day trippers, placing sites under huge strain.
威尼斯就像一颗脆弱的宝石，一方面面临着气候变化导致海平面上升的威胁，同时也需要应对大量游客带来的挑战。每年约有3000万名游客访问威尼斯，约三分之二是当天往返的一日游游客，这给威尼斯带来了游客大批涌入的巨大压力。

overtourism “过度旅游”，指游客数量过多Now they'll have to pay €5 to enter the city in a trial scheme in place on specific days over the next few months. The aim, say the authorities, is to discourage crowds descending at certain times, adding that the plan, the first such one in the world, could be extended in duration and price. Critics say the ticket is a minimal cost that will not address Venice's fundamental problems.
现在一项试行方案规定，在未来几个月的特定旅游高峰日，一日游游客们必须支付5欧元才能进城观光。威尼斯官方表示，这样做的目的是阻止人群在特定日子大批涌入威尼斯，并补充说，作为世界上首个推行 “进城费” 的方案，试行收费的时间可能会延长，价格也可能会上调。反对 “进城费” 方案的人说，收费很低，无法解决威尼斯面临的根本问题。
Other cities facing similar overtourism challenges will be watching closely to see if it works.
其它面临类似客流量过大问题的城市将密切关注该试行方案，看它是否奏效。

Dogs are in high demand as pets. In fact, 36% of households in the UK own one, according to the UK Pet Food survey 2024. Our canine pals can be cute, cuddly and loyal friends. But, for many owners, dogs are much more than this – they are a lifeline.
狗作为宠物的需求量很大。 事实上，根据 2024 年英国宠物食品调查，36% 的英国家庭拥有一只狗狗。我们的狗狗朋友可以是可爱、惹人喜爱且忠诚的朋友。 但是，对于许多主人来说，狗的意义远不止于此——它们是生命线。
Assistance dogs provide essential support, increased independence and companionship for disabled people and people with medical conditions – they have even saved lives. There are many different types of assistance dogs out there, from hearing dogs to autism dogs to guide dogs. But what makes the perfect assistance dog?
协助犬为残疾人和患有疾病的人提供必要的支持、增强的独立性和陪伴——它们甚至拯救了生命。 那里有许多不同类型的辅助犬，从助听犬到自闭症犬再到导盲犬。 但什么才是完美的协助犬呢？
Common assistance dog breeds are Labrador retrievers, golden retrievers and German shepherds. The most common guide dog in the UK is the golden retriever-Labrador cross, which, according to the Guide Dogs National Centre, has a 'combination of desirable traits'. Guide dogs need to be able to lead a blind or visually impaired person outside and inside, while avoiding distractions and recognising and avoiding obstacles such as changes in elevation, like tree roots, curbs and stairs. With that in mind, training puppies is essential.
常见的辅助犬品种有拉布拉多犬、金毛猎犬和德国牧羊犬。 英国最常见的导盲犬是金毛猎犬和拉布拉多杂交犬，根据国家导盲犬中心的说法，它具有“理想特征的组合”。 导盲犬需要能够在室外和室内引导盲人或视障人士，同时避免分心，识别和避开障碍物，例如海拔变化，如树根、路缘和楼梯。 考虑到这一点，训练小狗是至关重要的。
The Guide Dogs for the Blind Association trains puppies using positive reinforcement, rewarding good behaviour with food, praise and affection. When it comes to hearing dogs, a very important part of their training is sound awareness – alerting their deaf partner to sounds they would otherwise miss, for example a smoke alarm, an alarm clock or a crying baby. Katie Grundy, a puppy trainer at the charity Hearing Dogs for Deaf People, teaches puppies targeting, a technique where the dogs touch a target, like a hand, with their nose for a treat. This teaches hearing dogs how to notify their partner when a sound goes off.
盲人导盲犬协会使用积极强化的方式训练小狗，通过食物、赞美和关爱来奖励良好的行为。 对于听力狗来说，训练的一个非常重要的部分是声音意识——提醒聋哑伙伴注意他们可能会错过的声音，例如烟雾报警器、闹钟或哭闹的婴儿。 凯蒂·格伦迪（Katie Grundy）是慈善机构“聋人助听犬”的小狗训练师，她教小狗瞄准目标，这是一种狗用鼻子触摸目标（例如手）的技巧。 这教会听力狗如何在声音响起时通知其伴侣。
At the end of training, not all pups qualify, but they are put up for adoption and, of course, make excellent lovable pets.
训练结束时，并非所有幼犬都符合资格，但它们会被收养，当然，它们会成为优秀的可爱宠物。

American pop music star Madonna performed before an estimated 1.6 million people on Saturday at Brazil’s famous Copacabana Beach.
周六，美国流行音乐明星麦当娜在巴西著名的科帕卡巴纳海滩向估计 160 万人表演。
The outdoor show in Rio de Janeiro was free to attend.
里约热内卢的户外表演免费参加。
The fans turned a long stretch of the coast into a huge dance floor for the last show of Madonna’s Celebration Tour. The series began last October in London.
歌迷们把一段长长的海岸变成了一个巨大的舞池，为麦当娜庆祝巡演的最后一场演出。 该系列于去年十月在伦敦开始。
The so-called “Queen of Pop” began Saturday’s show with her 1998 song Nothing Really Matters. Huge cheers rose from the crowd pressed up against the barriers. Other attendees held parties in houses and hotels overlooking the beach. Helicopters and drones flew overhead, and boats floated on the water nearby.
这位所谓的“流行天后”以她 1998 年的歌曲《Nothing Real Matters》拉开了周六的演出的序幕。 挤在护栏上的人群中爆发出巨大的欢呼声。 其他与会者在俯瞰海滩的房屋和酒店举行聚会。 直升机和无人机在头顶飞过，船只漂浮在附近的水面上。
“Here we are in the most beautiful place in the world,” the 65-year-old Madonna told the crowd. Pointing out the ocean, the mountains and the Christ the Redeemer statue overlooking the city, she added: “This place is magic.”
“我们现在身处世界上最美丽的地方，”65 岁的麦当娜对人群说道。 她指着海洋、山脉和俯瞰城市的基督救世主雕像补充道：“这个地方很神奇。”
Madonna performed her popular songs, including Like A Virgin and Hung Up. For the introduction to another, Like A Prayer, Madonna covered her head in black cloth and held a rosary.
麦当娜表演了她的流行歌曲，包括《Like A Virgin》和《Hung Up》。 在另一首歌曲《Like A Prayer》的介绍中，麦当娜用黑布遮住头，并手持一串念珠。
The star honored those who died of AIDS with the song Live to Tell. Large black and white images of the disease’s victims appeared behind her as she sang. Later, she was joined on stage by Brazilian artists Anitta and Pabllo Vittar.
这位明星用歌曲《Live to Tell》向死于艾滋病的人们致敬。 当她唱歌时，该疾病受害者的大幅黑白图像出现在她身后。 随后，巴西艺术家 Anitta 和 Pabllo Vittar 也与她一起登上舞台。
Rio city officials estimated that 1.6 million people attended the show. Madonna’s official website called the show the biggest ever in her 40-year career.
里约市官员估计有 160 万人观看了演出。 麦当娜的官方网站称这场演出是她40年职业生涯中规模最大的一次。
“Since Madonna arrived here, I’ve been coming every day with this outfit to welcome my idol, my diva, my pop queen,” said 69-year-old retiree Rosemary de Oliveira Bohrer. She wore a gold-colored top and a black cap in a style that Madonna made popular.
“自从麦当娜来到这里以来，我每天都穿着这套衣服来欢迎我的偶像、我的天后、我的流行天后，”69 岁的退休人员罗斯玛丽·德奥利维拉·博雷尔 (Rosemary de Oliveira Bohrer) 说道。 她穿着金色上衣和黑色帽子，这种风格是麦当娜流行的。
Eighteen sound towers were spread along the beach to ensure that all attendees could hear the performance.
沿着海滩分布着十八座音塔，以确保所有参加者都能听到表演。
Fan Alessandro Augusto flew about 2,500 kilometers, from Brazil’s Ceara state to Rio, to attend the show. Augusto said, “It’s a unique opportunity to see Madonna, who knows if she’ll ever come back.”
范·亚历山德罗·奥古斯托 (Alessandro Augusto) 从巴西塞阿拉州飞往里约，飞行约 2500 公里来参加演出。 奥古斯托说：“这是一个见到麦当娜的独特机会，她知道她是否会回来。”
“Welcome Queen!” a drink company announced with advertising around the city. Bars and restaurants prepared special alcoholic drinks named after Madonna songs. A shop known for selling Carnival clothing temporarily became a “Madonna” clothing store.
“欢迎女王陛下！” 一家饮料公司宣布在城市各处做广告。 酒吧和餐馆准备了以麦当娜歌曲命名的特殊酒精饮料。 一家以销售嘉年华服装而闻名的商店暂时变成了“麦当娜”服装店。
Several huge concerts have taken place on Copacabana beach before, including musician Rod Stewart’s 1994 show. It took place on New Year’s Eve as part of the city’s holiday celebration. About 4 million people attended. However, not all necessarily took in the music show.
科帕卡巴纳海滩此前曾举办过几场大型音乐会，其中包括音乐家罗德·斯图尔特 (Rod Stewart) 1994 年的演出。 它发生在除夕夜，作为该市节日庆祝活动的一部分。 约有400万人参加。 然而，并非所有人都一定参加了音乐表演。
And, in 2006, a Rolling Stones concert drew 1.2 million people onto the famed beach, the newspaper Folha de Sao Paulo reported at the time.
据《圣保罗页报》当时报道，2006 年，滚石乐队的一场音乐会吸引了 120 万人来到这片著名的海滩。
Madonna fan Ana Beatriz Soares attended the show Saturday. She said Madonna has made her mark across the years.
麦当娜的粉丝安娜·贝阿特丽斯·苏亚雷斯周六出席了演出。 她说麦当娜多年来已经留下了自己的印记。
“Madonna had to run so that today’s pop artists could walk. That’s why she’s important, because she serves as an inspiration for today’s pop divas,” she said. “And that’s 40 years ago. Not 40 days, 40 months. It’s 40 years,” she added.
“麦当娜必须跑步，这样今天的流行艺术家才能走路。 这就是为什么她很重要，因为她是当今流行天后的灵感来源，”她说。 “那是 40 年前的事了。 不是40天，是40个月。 40 年了，”她补充道。

Financial support for climate technology startups in Africa from the private sector is growing. Businesses have raised more than $3.4 billion since 2019. However, the continent requires $277 billion each year to meet its climate goals for 2030.
私营部门对非洲气候技术初创企业的财政支持正在增加。 自 2019 年以来，企业已筹集超过 34 亿美元。然而，非洲大陆每年需要 2770 亿美元才能实现 2030 年的气候目标。
Experts say to receive more money, African countries need to deal with risks such as unexpected currency value changes. And they say investors need to expand into different climate sectors, including flood protection, disaster management and heat management. Investors should also use more kinds of funding methods.
专家表示，为了获得更多资金，非洲国家需要应对货币价值意外变化等风险。 他们表示，投资者需要扩展到不同的气候领域，包括防洪、灾害管理和热量管理。 投资者还应该采用更多种类的融资方式。
Africa: The Big Deal is a financial support database. It says that last year, climate tech startups on the continent raised $1.04 billion. That is a 9 percent increase from the year before and three times what they raised in 2019. That increase comes as overall money for startups in Africa fell last year.
Africa: The Big Deal 是一个金融支持数据库。 据称，去年非洲大陆的气候技术初创公司筹集了 10.4 亿美元。 这比前一年增长了 9%，是 2019 年筹集资金的三倍。这一增长是在去年非洲初创企业的总体资金下降的情况下实现的。
The money climate tech startups raised last year was more than one-third of all monies raised by startups in Africa in 2023. It came in second to financial technology, a more established sector.
去年，气候科技初创公司筹集的资金占 2023 年非洲初创公司筹集资金总额的三分之一以上。它位居第二，仅次于更为成熟的金融技术领域。
Venture capital is usually given to business with large risk but great long-term growth possibilities. Startups use it to expand into new markets and to get products and services on the market.
风险投资通常给予风险较大但长期增长潜力巨大的企业。 初创公司利用它来拓展新市场并将产品和服务推向市场。
Even with the noted growth, private sector financing represented only 14 percent of all of Africa’s climate finance from 2019 to 2020. That information comes from a study by Climate Policy Initiative, a finance and policy research organization.
尽管增长显着，但 2019 年至 2020 年，私营部门融资仅占非洲气候融资总额的 14%。该信息来自金融和政策研究组织气候政策倡议的一项研究。
That number is far lower than in other parts of the world. In East Asia and the Pacific, for example, private sector financing represents 39 percent of climate finance. And in Latin America and the Caribbean, it makes up 49 percent.
这个数字远远低于世界其他地区。 例如，在东亚和太平洋地区，私营部门融资占气候融资的 39%。 在拉丁美洲和加勒比海地区，这一比例为 49%。
Sandy Okoth works at FSD Africa. The non-profit organization receives funding from the British government. Okoth said the low financial support in Africa is linked to investors putting money in areas they are more familiar with, such as renewable energy technology. Less money comes in for “more complex” technology, Okoth said. That includes technology for adapting to climate change, he added.
桑迪·奥科斯 (Sandy Okoth) 在 FSD Africa 工作。 该非营利组织接受英国政府的资助。 奥科斯表示，非洲的财政支持较低与投资者将资金投入他们更熟悉的领域有关，例如可再生能源技术。 奥科斯说，“更复杂”的技术投入的资金更少。 他补充说，这包括适应气候变化的技术。
Wetility is a renewable energy startup based in South Africa. Last year, it secured funding of $48 million, mostly from private equity, to expand its operations.
Wetility 是一家位于南非的可再生能源初创公司。 去年，该公司获得了 4800 万美元的资金，主要来自私募股权，用于扩大业务。
The startup provides solar panels for homes and businesses and an online service that permits users to remotely access power usage. It aims to solve the problems of energy access and dependability in southern Africa.
该初创公司为家庭和企业提供太阳能电池板，并提供允许用户远程访问用电情况的在线服务。 它旨在解决南部非洲的能源获取和可靠性问题。
Vincent Maposa is founder and chief executive officer of Wetility. He said, “Private sector financing in African climate is still rather low.” But he added that there is clear growth.
Vincent Maposa 是 Wetility 的创始人兼首席执行官。 他说：“非洲气候下的私营部门融资仍然相当低。” 但他补充说，增长明显。
Maëlis Carraro is partner at Catalyst Fund. The Kenya-based venture capital fund supports climate adaption solutions. She urged for more diverse funding, such as mixing private and public sector funding together.
Maëlis Carraro 是 Catalyst 基金的合伙人。 总部位于肯尼亚的风险投资基金支持气候适应解决方案。 她敦促提供更加多样化的资金，例如将私人和公共部门的资金混合在一起。
She said one aim of public financing should be to bring more private sector capital into financing climate initiatives.
她表示，公共融资的目标之一应该是吸引更多私营部门资本为气候举措提供融资。
She added, “We need the private sector and the public sector to work together to unlock more financing.”
她补充道，“我们需要私营部门和公共部门共同努力，释放更多资金。”

Robert Burns is widely regarded as the national poet of Scotland, perhaps best known for Auld Lang Syne, which is sung across the world on Hogmanay.
罗伯特·彭斯被公认为是苏格兰的民族诗人，他最著名的作品应该就是《友谊地久天长》，这首歌在新年前夜被全世界传唱。
The National Trust for Scotland's online portal will allow people to view fragments of one of only six known manuscripts of the poem, dating from 1793.
苏格兰国民信托的在线门户网站将允许人们查看这首诗仅存的六份手稿其中之一的碎片，手稿年份可以追溯到1793年。
The wedding ring of Burns's wife Jean Armour will also be on show, as will a lock of hair belonging to the woman believed to have inspired the song 'Highland Mary'. A blue monogrammed sock is also featured. It reveals Burns was a size eight.
展品还包括彭斯妻子简·阿莫尔的婚戒、一缕头发——据说这缕头发的主人正是启发彭斯创作歌曲《高原玛丽》的那位女士。此外，还有一只织有花押字的蓝色袜子，从这只袜子可以看出，彭斯穿8码的鞋子。

Over half of American TV viewers now use subtitles whenever they watch TV, according to survey company YouGov. This trend is even more noticeable in viewers under 30. Subtitles have long been used to help people with hearing impairments or to allow people to watch films in a different language, but why has their use become so widespread?
据调查公司 YouGov 称，现在超过一半的美国电视观众在看电视时都会使用字幕。 这种趋势在 30 岁以下的观众中更为明显。长期以来，字幕一直被用来帮助听力障碍人士或让人们观看不同语言的电影，但为什么字幕的使用变得如此广泛？
The reasons for this are both technical and social. Advances in digital sound production and microphones mean that actors can be more natural in their vocal performance, while at the same time audio directors are able to make more and more dramatic soundscapes. Combined with the much smaller speakers contained in modern TV sets, this can all make dialogue seem unintelligible.
造成这种情况的原因既有技术原因，也有社会原因。 数字声音制作和麦克风的进步意味着演员的声乐表演可以更加自然，同时音频导演也能够制作出越来越戏剧性的音景。 再加上现代电视机中包含的小得多的扬声器，这一切都会使对话显得难以理解。
Smartphones may play a role. We are used to subtitled social media videos that can be watched without headphones. Smartphones also allow us to watch film and TV in public places where they are not easily audible. Another social reason could be the increased appetite for programmes in other languages accessible through international streaming services.
智能手机可能会发挥一定作用。 我们已经习惯了无需耳机即可观看的带字幕的社交媒体视频。 智能手机还允许我们在不易被听到的公共场所观看电影和电视。 另一个社会原因可能是人们对通过国际流媒体服务访问的其他语言节目的兴趣增加。
While some viewers may consider subtitles to be distracting, or worry about the potential for spoilers, they don't just help with unclear audio. A number of studies have suggested that subtitles could help people to increase their vocabulary and boost their listening skills in languages that they do not currently speak.
虽然一些观众可能认为字幕会分散注意力，或者担心可能会剧透，但它们不仅仅有助于解决不清楚的音频。 许多研究表明，字幕可以帮助人们增加词汇量并提高他们目前不会说的语言的听力技能。
This may be particularly effective when subtitles are in the same language as the audio track of the programme. Same-language subtitles have also been shown to help young children develop their reading skills in their first language, to the point where campaigners have suggested enabling subtitles on all children's programmes by default.
当字幕与节目音轨采用相同语言时，这可能特别有效。 同语言字幕也被证明可以帮助幼儿发展母语的阅读技能，以至于活动人士建议默认在所有儿童节目中启用字幕。

Worobey said the virus likely spreads among the cows due to contact with milking machines, trucks or the shoes of farm workers. It then moves from cow to cow before making its way back to birds. Worobey said birds tested on the same farms as sick cows have a form of the virus with “clear mammalian adaptations.” In other words, the virus shows signs of changing before infecting the bird populations.
沃罗比说，由于接触挤奶机、卡车或农场工人的鞋子，病毒可能在奶牛之间传播。然后它从一头牛转移到另一头牛，最后又回到鸟类身上。沃罗比说，在与病牛相同的农场进行测试的鸟类携带了一种具有“明显的哺乳动物适应性”的病毒。换句话说，病毒在感染鸟类之前就表现出了变化的迹象。
Scientists say the best way to keep the virus from spreading to more cows, and possibly humans, is to test cows as often as possible and follow their movements.
科学家表示，防止病毒传播给更多奶牛（甚至可能是人类）的最佳方法是尽可能频繁地对奶牛进行检测并跟踪它们的活动。
Thomas Friedrich is a virology expert at the University of Wisconsin’s animal medical school. “We need to be able to do greater surveillance so that we know what’s going on.”
托马斯·弗里德里希是威斯康星大学动物医学院的病毒学专家。“我们需要能够进行更大规模的监视，以便我们知道发生了什么。”
Worobey said testing for active virus is one thing. But the tests must also look for antibodies, or evidence of past infections.
沃罗贝说，检测活性病毒是一回事。但测试还必须寻找抗体或过去感染的证据。
“That is a really accessible and quick way to find out how widespread this is,” he said.
他说：“这是了解这种情况有多普遍的一种非常容易且快速的方法。”
Scientists are working to be sure that heating up the milk before it is put into containers for humans to drink is enough to kill the virus. The process is called pasteurization. The U.S. Food and Drug Administration (FDA) will have more information about that soon.
科学家们正在努力确保在将牛奶放入容器供人类饮用之前将其加热足以杀死病毒。该过程称为巴氏灭菌。美国食品和药物管理局 (FDA) 将很快提供更多相关信息。
Right now, the FDA recommends humans to avoid raw or unpasteurized milk. Farm workers are also being told to wear masks, wash their hands and change their work clothes often, Aliota said.
目前，美国食品和药物管理局建议人们避免食用生牛奶或未经高温消毒的牛奶。阿利奥塔说，农场工人还被告知要戴口罩、勤洗手并经常更换工作服。
The U.S. Centers for Disease Control and Prevention said 23 people have been tested for the virus so far. One person has tested positive for a mild eye infection. CDC officials are watching for signs of sickness in 44 other people who were in contact with infected animals.
美国疾病控制与预防中心表示，迄今为止已有 23 人接受了病毒检测。一名患者轻度眼部感染检测呈阳性。CDC 官员正在观察另外 44 名接触过受感染动物的人是否有生病迹象。
David O’Connor is a virus expert at the University of Wisconsin-Madison. He said that knowing about the virus should not make humans “change anything about how (they) live their daily lives.”
大卫·奥康纳是威斯康星大学麦迪逊分校的病毒专家。他说，了解这种病毒不应让人类“改变他们的日常生活方式”。
But he said humans should have “increased awareness that something is happening.”

The United States plans new rules for the movement of dairy cows between states because of concerns about a bird flu outbreak.
出于对禽流感爆发的担忧，美国计划对各州之间奶牛的流动制定新规则。
The virus is called Type A H5N1. It has been found in over 30 different groups of cows across eight states.
该病毒被称为 A 型 H5N1。 已在 8 个州的 30 多个不同的奶牛群中发现了这种病毒。
Some inactive markers of the virus have been found in milk sold in stores. Inactive markers mean the virus is dead and cannot harm humans who drink the milk.
在商店出售的牛奶中发现了一些非活性病毒标记。 不活跃的标记意味着病毒已经死亡，不会伤害喝牛奶的人。
The concern is that the virus could mutate, or change. It could then possibly spread from cows or other animals to humans. Experts, however, believe the risk of that is low.
令人担忧的是病毒可能会变异或改变。 然后它可能从牛或其他动物传播到人类。 然而，专家认为这种风险很低。
After April 29, cows must have been tested and found to not have the virus before they are permitted to be moved between states.
4 月 29 日之后，奶牛必须经过检测并发现没有携带病毒，然后才能获准在各州之间转移。
The virus has been known by scientists to circulate among wild birds. It appears in other animals if they eat sick birds. Some animals that live near the sea have tested positive for the virus, including harbor seals and polar bears. Animals that eat grasses, such as cows and goats, have only recently been found to have the virus.
科学家已知该病毒在野生鸟类中传播。 如果其他动物吃了病鸟，也会出现这种情况。 一些生活在海边的动物的病毒检测呈阳性，包括斑海豹和北极熊。 直到最近才发现牛和山羊等吃草的动物携带这种病毒。
Richard Webby is an influenza expert at St. Jude’s Children’s Research Hospital in Tennessee. He said flu viruses are known for adapting to spread among new animals. Finding the virus in dairy milk raises concerns that it could spread to people, Webby said.
理查德·韦比是田纳西州圣裘德儿童研究医院的流感专家。 他说，众所周知，流感病毒能够适应在新动物之间的传播。 韦比说，在牛奶中发现这种病毒引发了人们对其可能传播给人类的担忧。
Scientists confirmed the virus in cows in March after farmers said their cows were sick. They said the animals’ symptoms included tiredness and low milk production. Some farmers said the milk the sick cows produced was thick and yellow.
三月份，在农民表示他们的奶牛生病后，科学家们证实了奶牛体内存在这种病毒。 他们说，这些动物的症状包括疲倦和产奶量低。 一些农民表示，病牛产出的牛奶又浓又黄。
Matthew Aliota is an animal medicine researcher at the University of Minnesota. He said finding the inactive virus in the milk “suggests this has been going on longer, and is more widespread, than we have previously recognized.”
马修·阿利奥塔（Matthew Aliota）是明尼苏达大学的动物医学研究员。 他说，在牛奶中发现失活病毒“表明这种情况持续的时间比我们之前认识的要长，而且范围更广。”
The U.S. Department of Agriculture recently sent out new genetic information about the virus.
美国农业部最近发布了有关该病毒的新基因信息。
Michael Worobey is an evolutionary biologist with the University of Arizona. He said the federal agency information makes him think the virus moved from birds to cows late in 2023.
迈克尔·沃罗贝 (Michael Worobey) 是亚利桑那大学的进化生物学家。 他说，联邦机构的信息让他认为病毒在 2023 年底从鸟类转移到了牛身上。

Heavy rains and severe flooding have been hitting Kenya since March. They are among the most disastrous rainstorms to hit the East African country in recent years.
自三月以来，肯尼亚遭受暴雨和严重洪水袭击。 这是近年来袭击这个东非国家的最具灾难性的暴雨之一。
At least 169 people have died from the heavy rains. At least 91 others are missing, the latest government estimates say.
至少有169人因暴雨死亡。 政府最新估计称，至少还有 91 人失踪。
On Monday, at least 48 people died after water blew through a blocked river tunnel under a railway line in southwestern Kenya.
周一，肯尼亚西南部铁路线下一条被堵塞的河流隧道被洪水冲破，造成至少 48 人死亡。
The flooding has displaced more than 190,000 people and damaged roads and other structures.
洪水导致超过 190,000 人流离失所，道路和其他建筑物受损。
Seasonal weather patterns, climate change and other natural weather events all combine to create deadly rainstorms.
季节性天气模式、气候变化和其他自然天气事件结合在一起，造成了致命的暴雨。
Kenya and some other parts of eastern Africa have two main rainfall periods: the “long rains” season from March to May, and the “short rains” season from October to December.
肯尼亚和东非其他一些地区有两个主要降雨期：3月至5月的“长雨”季节和10月至12月的“短雨”季节。
The “long rains” season is when most of the country’s average yearly rainfall happens.
“长雨”季节是该国年平均降雨量的大部分时间。
In its forecast for this year’s “long rains” season, the Kenya Meteorological Department predicted above-average rainfall in many parts of the country. It also warned of flooding, landslides and other harmful effects.
肯尼亚气象部门在对今年“长雨”季节的预测中预计，该国许多地区的降雨量将高于平均水平。 它还警告洪水、山体滑坡和其他有害影响。
Last year’s “short rains” season saw severe storms in many parts of the country. The meteorological department said Lamu, Mombasa and Garissa areas received nearly three times their long-term average rainfall.
去年“短雨”季节，全国多地遭遇严重风暴。 气象部门表示，拉穆、蒙巴萨和加里萨地区的降雨量几乎是长期平均降雨量的三倍。
Kenya's rainfall frequency and intensity are affected by a natural climate system called the Indian Ocean Dipole.
肯尼亚的降雨频率和强度受到称为印度洋偶极子的自然气候系统的影响。
The Indian Ocean Dipole makes the surface of the western Indian Ocean warmer and then colder than the eastern Indian Ocean. It causes heavy rainfall in areas west of the Indian Ocean, such as Kenya, and droughts in Indonesia and Australia.
印度洋偶极子使西印度洋的表面比东印度洋先暖后冷。 它导致肯尼亚等印度洋以西地区出现强降雨，并导致印度尼西亚和澳大利亚出现干旱。
Joyce Kimutai is a researcher at Imperial College London. She said that, in Kenya’s case, the Indian Ocean Dipole and climate change are likely bringing more severe rainfall and flooding.
乔伊斯·基穆泰 (Joyce Kimutai) 是伦敦帝国理工学院的研究员。 她说，就肯尼亚而言，印度洋偶极子和气候变化可能会带来更严重的降雨和洪水。
In a study in December last year, Kimutai and other scientists from World Weather Attribution found that human-caused climate change had made last year’s “short rains” season in Kenya and other parts of eastern Africa up to two times more intense.
在去年 12 月的一项研究中，Kimutai 和世界天气归因组织的其他科学家发现，人为造成的气候变化使肯尼亚和东非其他地区去年的“短雨”季节强度增加了两倍。
It has become more difficult to predict long-term weather in Kenya in recent years. The start and the length of dry and wet seasons have increasingly changed.
近年来，预测肯尼亚的长期天气变得更加困难。 旱季和雨季的开始和长度发生了越来越大的变化。
The Kenya Meteorological Department expects the “long rains” season to continue into June. In its latest weather report on Monday, the department said it expects heavy rain in six areas of the country. It also predicted flooding in low-lying areas and landslides in hilly areas.
肯尼亚气象部门预计“长雨”季节将持续到六月。 该部门在周一最新的天气报告中表示，预计该国六个地区将出现大雨。 它还预测了低洼地区的洪水和丘陵地区的山体滑坡。
Flooding in East Africa also has killed more than 150 people in neighboring Tanzania and Somalia. It has also affected hundreds of thousands of people in Ethiopia and Burundi.
东非的洪水也导致邻国坦桑尼亚和索马里的 150 多人死亡。 它还影响了埃塞俄比亚和布隆迪的数十万人。

Less than half of Americans say they are getting enough sleep, according to a recent opinion study by the Gallup organization.
盖洛普组织最近的一项民意研究显示，不到一半的美国人表示他们睡眠充足。
The poll found that 57 percent of Americans say they would feel better if they could get more sleep. Only 42 percent say they are getting as much sleep as they need.
民意调查发现，57% 的美国人表示，如果能够获得更多睡眠，他们会感觉更好。 只有 42% 的人表示他们的睡眠充足。
Gallup carried out the same kind of study in 2013. That time, the results were different. Fifty-six percent said they got enough sleep, while 43 percent said they did not get enough sleep.
盖洛普在2013年进行了同类研究，但当时的结果有所不同。 56% 的人表示他们睡眠充足，43% 的人表示他们睡眠不足。
Women under the age of 50 were the most likely to report they are not getting enough rest. Only 27 percent of women in that group said they usually get all the sleep they need.
50 岁以下的女性最有可能报告她们没有得到足够的休息。 该群体中只有 27% 的女性表示她们通常能获得所需的全部睡眠。
The poll also asked people to report how many hours of sleep they usually get each night. Only 26 percent said they got eight or more hours. Many sleep experts say adults should aim for eight hours of sleep a night.
该民意调查还要求人们报告他们通常每晚的睡眠时间。 只有 26% 的人表示他们有 8 个小时或更长时间。 许多睡眠专家表示，成年人的目标应该是每晚睡八小时。
Just over half of the respondents reported getting between six and seven hours of sleep a night. And 20 percent said they got five hours or less. That number increased from 2013, when 14 percent of respondents reported getting five hours or less.
超过一半的受访者表示每晚睡眠六到七个小时。 20% 的人表示他们的时间不超过五个小时。 这个数字比 2013 年有所增加，当时 14% 的受访者表示工作时间为 5 小时或更少。
Justine Broughal is a self-employed event planner with two small children. She is 31 years old. Her 4-month-old son still wakes up throughout the night. After her 3-year-old daughter goes to bed, she still needs to do some work in the house. That makes it difficult for her to get the sleep she needs.
贾斯汀·布鲁尔 (Justine Broughal) 是一名自营活动策划者，有两个小孩。 她今年 31 岁。 她四个月大的儿子仍然整夜醒来。 3岁的女儿睡觉后，她还需要做一些家务。 这使她很难获得所需的睡眠。
“I really treasure being able to spend time with (my children),” Broughal says. However, she added that it can reduce the amount of time for her to rest and take care of herself.
“我真的很珍惜能够与（我的孩子们）共度时光，”布鲁尔说。 然而，她补充说，这会减少她休息和照顾自己的时间。
Claude Fischer is a professor of sociology at the University of California, Berkeley. He said that American culture has valued hard work and productivity since the first European immigrants arrived. He added that the religious beliefs of some groups connected hard work with approval from God.
克劳德·费舍尔是加州大学伯克利分校的社会学教授。 他说，自从第一批欧洲移民抵达以来，美国文化就重视努力工作和生产力。 他补充说，一些群体的宗教信仰将努力工作与上帝的认可联系在一起。
Working hard, he said, “has been a core part of American culture for centuries.”
他说，努力工作“几个世纪以来一直是美国文化的核心部分。”
Some Americans also say their busy workdays make them want to stay up late. After a long day of work, spending time at night on social media or watching television can help them lower stress or have some time to themselves. But this reduces the number of hours they can sleep.
一些美国人还表示，忙碌的工作日让他们想熬夜。 经过一整天的工作后，晚上花时间浏览社交媒体或看电视可以帮助他们减轻压力或享受一些独处的时间。 但这会减少他们的睡眠时间。
Liz Meshel has experienced this. The 30-year-old American is temporarily living and doing research in Bulgaria. But she also works a part-time job on U.S. hours to help pay her bills. That means she sometimes works until 10 at night local time.
莉兹·梅舍尔就经历过这一点。 这位30岁的美国人暂时在保加利亚生活和研究。 但她也在美国工作时间做兼职，以帮助支付账单。 这意味着她有时会工作到当地时间晚上 10 点。
When it is close to her bedtime, she said she thinks about the time she did not have for herself during the day. So, she decides to watch television and look at social media instead of getting to sleep earlier.
当临近睡觉时间时，她说她会想起白天没有属于自己的时间。 因此，她决定看电视和浏览社交媒体，而不是早点睡觉。
That, Meshel said, “will always make the problem worse.”
梅舍尔说，这“总是会让问题变得更糟。”

for example, when the Curiosity rover drives over the area.
例如当好奇号火星车驶过该地区时，也可能释放少量甲烷。
Pavlov said this theory could help explain why methane levels have only been discovered in the Gale Crater area. It is the only place on Mars where NASA’s Curiosity rover is currently active.
巴甫洛夫说，这一理论可以帮助解释为什么只在盖尔陨石坑地区发现了甲烷水平。 这是美国宇航局好奇号火星车目前在火星上唯一活跃的地方。
NASA has another rover working on Mars, Perseverance. But it has been exploring the Jezero Crater area on another part of the planet. Jezero Crater is also believed to have contained large water bodies in the distant past. But Perseverance is not equipped with a methane-detecting instrument.
美国宇航局还有另一辆火星车“毅力号”正在火星上工作。 但它一直在探索地球另一部分的杰泽罗陨石坑地区。 据信，杰泽罗陨石坑在遥远的过去也曾存在过大型水体。 但毅力号并未配备甲烷检测仪器。
Pavlov noted that the latest theory came from his memories of an unrelated experiment carried out in 2017. The experiment involved growing microorganisms in a simulated Martian environment that included frozen soil that contained salt.
巴甫洛夫指出，最新的理论来自他对 2017 年进行的一项无关实验的记忆。该实验涉及在模拟火星环境中培养微生物，其中包括含盐的冻土。
During that experiment, researchers observed that the collection of soil on top formed an icy, salty crust. Changes in conditions caused the ice to melt, turning the solid material into a gas and leaving the salt behind.
在那次实验中，研究人员观察到顶部的土壤聚集形成了冰冷的咸味外壳。 条件的变化导致冰融化，将固体物质变成气体并留下盐。
Pavlov’s team tested five samples of frozen soil containing different kinds of salt material commonly found on Mars. A new set of Earth-based experiments was carried out in which the frozen material was exposed to different temperatures and air pressures inside an environment at Goddard that was designed to be like Mars.
巴甫洛夫的团队测试了五个冻土样本，其中含有火星上常见的不同种类的盐物质。 进行了一系列新的地球实验，其中将冷冻材料暴露在戈达德的一个设计为类似于火星的环境中的不同温度和气压下。
The team was able to repeatedly copy the salt sealing process in Mars-like conditions during laboratory testing. The researchers said they plan to keep carrying out experiments under different conditions and using salt minerals to confirm their theory.
该团队能够在实验室测试期间重复复制类似火星条件下的盐密封过程。 研究人员表示，他们计划继续在不同条件下进行实验，并利用盐矿物质来证实他们的理论。
But the researchers noted that to carry out more detailed methane investigations, they will likely need a whole new generation of sensitive instruments. These would be designed to measure methane continuously from many places on Mars.
但研究人员指出，为了进行更详细的甲烷研究，他们可能需要全新一代的敏感仪器。 这些将被设计用于从火星上的许多地方连续测量甲烷。

Scientists are seeking to find out what is producing the slow release of methane gas on Mars.
科学家们正在寻找火星上缓慢释放甲烷气体的原因。
Methane often results from biological processes. On Earth, most of the gas comes from living creatures. For this reason, the American space agency NASA has been investigating methane levels on Mars in a search for signs of current or past life. So far, no evidence has been found.
甲烷通常来自生物过程。 在地球上，大部分气体来自生物。 出于这个原因，美国宇航局NASA一直在调查火星上的甲烷水平，以寻找当前或过去生命的迹象。 到目前为止，还没有找到任何证据。
But a new study is providing fresh details about methane on Mars. NASA’s Curiosity explorer, or rover, has repeatedly measured methane levels on the Martian surface. The rover arrived on Mars in 2012 and has been exploring areas around Gale Crater. This area is believed to have contained a lake at one time and has also shown other evidence of flowing water in the past.
但一项新研究提供了有关火星甲烷的新细节。 美国宇航局的好奇号探测器或漫游者多次测量了火星表面的甲烷水平。 该火星车于 2012 年抵达火星，一直在探索盖尔陨石坑周围的区域。 据信该地区曾经有一个湖泊，并且过去还显示出其他流水的证据。
NASA says Gale Crater is the only place where methane has been discovered. Even a spacecraft sent to collect data on the Martian atmosphere has not identified the presence of methane. That spacecraft, the ExoMars Trace Gas Orbiter, is operated by the European Space Agency.
美国宇航局表示，盖尔陨石坑是唯一发现甲烷的地方。 即使是派去收集火星大气数据的航天器也没有发现甲烷的存在。 该航天器名为 ExoMars 痕量气体轨道飞行器，由欧洲航天局运营。
In addition to only being discovered, or detected, around Gale Crater, the observations of methane happen only at night, NASA researchers recently reported. Levels also go up and down during different seasons and at times, rise sharply for short periods.
美国宇航局研究人员最近报告说，除了仅在盖尔陨石坑周围发现或探测到甲烷之外，甲烷的观测也只发生在夜间。 水平也会在不同季节上下波动，有时会在短时间内急剧上升。
The mysterious methane releases leave scientists considering “a lot of plot twists,” said Curiosity project leader Ashwin Vasavada. But a NASA research group recently proposed a possible explanation for how the gas behaves on Mars.
好奇号项目负责人阿什温·瓦萨瓦达 (Ashwin Vasavada) 表示，神秘的甲烷释放让科学家们思考“许多情节曲折”。 但美国宇航局的一个研究小组最近对火星上的气体行为提出了一个可能的解释。
The researchers theorize that all detected methane could be trapped, or sealed, underneath hardened pieces of salt in Martian regolith. Regolith describes soil that contains rock and dust that sits on or below the surface.
研究人员推测，所有检测到的甲烷都可能被捕获或密封在火星风化层的硬化盐块下面。 风化层描述的是含有岩石和灰尘的土壤，位于地表之上或之下。
The scientists say increases in temperature might explain the differences in gas release. During certain seasons or times of day warmer temperatures could weaken the seal on the methane, causing gas to be released.
科学家们表示，温度升高可能可以解释气体释放的差异。 在某些季节或一天中的某些时间，气温升高可能会削弱甲烷的密封性，导致气体释放。
NASA said the research was led by Alexander Pavlov, a planetary scientist at the agency’s Goddard Space Flight Center in Maryland. He said small amounts of methane could also be released when the regolith seal is broken by weight from above
美国宇航局表示，这项研究是由该机构马里兰州戈达德太空飞行中心的行星科学家亚历山大·巴甫洛夫领导的。 他说，当风化层密封被上方的重量破坏时。

Human experts spend years roasting and tasting coffee from many places to learn about the beans. They might then combine a coffee bean from Africa with another one from South America to come up with a new blend.
人类专家花费数年时间从许多地方烘焙和品尝咖啡，以了解咖啡豆。 然后，他们可能会将非洲的一种咖啡豆与南美的另一种咖啡豆结合起来，制成一种新的混合物。
But, a coffee roasting company in Helsinki, Finland is hoping that artificial intelligence, or AI, can help ease the workload.
但是，芬兰赫尔辛基的一家咖啡烘焙公司希望人工智能能够帮助减轻工作量。
Kaffa Roastery recently launched its “AI-conic” blend at the Helsinki Coffee Festival. The blend is a mixture of four kinds of beans, including Fazenda Pinhal from Brazil. It is the result of a joint project by Kaffa and Elev, a local AI business.
Kaffa Roastery 最近在赫尔辛基咖啡节上推出了“AI-conic”混合咖啡。 该混合物由四种咖啡豆混合而成，其中包括来自巴西的 Fazenda Pinhal。 它是 Kaffa 和当地人工智能企业 Elev 联合项目的成果。
Elev told The Associated Press that its computer models, similar to ChatGPT and Copilot, created a blend that would “push the boundaries of conventional flavor combinations.”
Elev 告诉美联社，其计算机模型与 ChatGPT 和 Copilot 类似，创造了一种混合物，可以“突破传统风味组合的界限”。
Svante Hampf is the founder of Kaffa Roastery. He and his partners wanted to do an experiment to see what blend the computer would produce.
Svante Hampf 是卡法烘焙工坊的创始人。 他和他的合作伙伴想做一个实验，看看计算机会产生什么混合物。
“We basically gave descriptions of all our coffee types and their flavors to AI and instructed it to create a new exciting blend,” Hampf said.
“我们基本上向人工智能提供了所有咖啡类型及其口味的描述，并指示它创造出一种新的令人兴奋的混合物，”汉普夫说。
The “AI-conic” blend combined beans from Brazil, Colombia, Ethiopia and Guatemala. It is described as “a well-balanced blend of sweetness and ripe fruit.”
“AI-conic”混合咖啡豆融合了来自巴西、哥伦比亚、埃塞俄比亚和危地马拉的咖啡豆。 它被描述为“甜味和成熟水果的均衡混合”。
Hampf said he thought the combination was “somewhat weird.” He was surprised that the AI program chose to make the blend out of four different kinds of beans. Most humans choose only two or three beans.
汉普夫说他认为这种组合“有点奇怪”。 他对人工智能程序选择用四种不同种类的豆子进行混合感到惊讶。 大多数人只选择两到三种豆子。
However, after the first blind test of the new blend, Kaffa’s coffee experts agreed that the AI-assisted blend was perfect. There was no need to change.
然而，在对新混合咖啡进行第一次盲测后，Kaffa 的咖啡专家一致认为人工智能辅助混合咖啡是完美的。 没有必要改变。
Elev’s Antti Merilehto said “AI-conic” is an example of “how AI can introduce new perspectives to seasoned professionals.”
Elev 的 Antti Merilehto 表示，“AI-conic”是“人工智能如何为经验丰富的专业人士引入新视角”的一个例子。
The International Coffee Organization says that the 5.6 million people in Finland drink the most coffee per person in the world. And the roasters at Kaffa said they hope the AI project will help to bring more things to the strong coffee culture in the country.
国际咖啡组织表示，芬兰 560 万人的人均咖啡饮用量位居世界第一。 Kaffa 的烘焙师表示，他们希望人工智能项目能够为该国浓厚的咖啡文化带来更多东西。
Hampf called it a “first step,” adding, “I think AI has plenty to offer us in the long run. We are particularly impressed of the coffee taste descriptions it created.”
汉普夫称其为“第一步”，并补充道，“我认为从长远来看，人工智能可以为我们提供很多东西。 它所创造的咖啡口味描述给我们留下了特别深刻的印象。”

A new, small robotic camera designed to be swallowed for use in medical examinations was recently demonstrated at a conference in Canada. The device called PillBot can be guided through a body remotely, meaning electronically from outside. Its creators hope the device will replace traditional endoscopies. An endoscopy is when a camera attached to a wire is directed down the throat and into a sleeping patient’s stomach.
最近在加拿大的一次会议上展示了一种新型小型机器人相机，其设计可被吞咽以用于医学检查。 这种名为 PillBot 的设备可以通过身体远程引导，即从外部以电子方式引导。 它的创造者希望该设备能够取代传统的内窥镜。 内窥镜检查是将连接在电线上的摄像头引导到熟睡患者的喉咙并进入胃部。
The company Endiatx based in Hayward, California, developed the device. The research hospital, Mayo Clinic, in Rochester, Minnesota, is a partner in the project.
总部位于加利福尼亚州海沃德的 Endiatx 公司开发了该设备。 位于明尼苏达州罗彻斯特的研究医院梅奥诊所是该项目的合作伙伴。
The PillBot is designed to be the first motorized endoscopic camera. Here is how developers say it works: A patient does not eat for one day, then swallows the PillBot with lots of water. The PillBot acts like a small submarine controlled by a wireless remote control. When the exam is complete, the body will expel the PillBot in the same way it expels other solid waste.
PillBot 被设计为第一台电动内窥镜摄像机。 开发人员介绍其工作原理是这样的：患者一天不进食，然后用大量的水吞下 PillBot。 PillBot 就像一艘由无线遥控器控制的小型潜艇。 检查完成后，身体会像排出其他固体废物一样排出 PillBot。
Dr. Vivek Kumbhari is co-founder of the company. He is professor of medicine and chairman of gastroenterology and hepatology at the Mayo Clinic. It is the latest step toward his larger goal of making complex medicine more accessible.
Vivek Kumbhari 博士是该公司的联合创始人。 他是梅奥诊所的医学教授兼胃肠病学和肝病学主席。 这是他朝着让复杂医学更容易获得的更大目标迈出的最新一步。
If endoscopies can be moved from a hospital setting to a patient’s home, he said, "then I think we have achieved that goal." Use of the device would require fewer medical workers and no anesthesia, he said. The device provides "a safer, more comfortable approach,” he added.
他说，如果内窥镜检查可以从医院转移到患者家中，“那么我认为我们已经实现了这一目标。” 他说，使用该设备将需要更少的医务人员，并且不需要麻醉。 他补充说，该设备提供了“一种更安全、更舒适的方法”。
Kumbhari also said the technology is more efficient and permits people to get treatment earlier in the progress of a disease.
Kumbhari 还表示，该技术更有效，可以让人们在疾病进展的早期得到治疗。
Alex Luebke is the co-founder of Endiatx. He said the PillBot can help people in rural areas where medical centers and treatment are lacking.
Alex Luebke 是 Endiatx 的联合创始人。 他说 PillBot 可以帮助缺乏医疗中心和治疗的农村地区的人们。
"Especially in developing countries, there is no access" to complex medical care, he said. "So being able to have the technology, gather all that information and provide you the solution, even in remote areas - that's the way to do it.”
他说，“特别是在发展中国家，无法获得”复杂的医疗服务。 “因此，即使在偏远地区，也能够拥有技术、收集所有信息并为您提供解决方案 - 这就是做到这一点的方法。”
The micro-robotic pill is undergoing testing. It could come before the U.S. Food and Drug Administration for consideration in the coming months. If approved, the PillBot could be available by 2026.
微型机器人药丸正在接受测试。 它可能会在未来几个月内提交美国食品和药物管理局考虑。 如果获得批准，PillBot 可能会在 2026 年上市。
Kumbhari hopes the technology can be expanded to the bowels, vascular system, heart, liver, brain and other parts of the body.
Kumbhari希望这项技术能够扩展到肠道、血管系统、心脏、肝脏、大脑和身体的其他部位。

International health experts have agreed on a new definition of what it means for a disease to spread “through the air.”
国际卫生专家就疾病“通过空气”传播的含义达成了新的定义。
The agreement came after the World Health Organization (WHO) cooperated with hundreds of international health experts to explain or clarify the meaning. The WHO said the technical document it issued was the first step towards finding better methods to prevent airborne disease spread.
该协议是在世界卫生组织（WHO）与数百名国际卫生专家合作解释或澄清其含义后达成的。 世界卫生组织表示，其发布的技术文件是寻找更好的方法来防止空气传播疾病传播的第一步。
The document says the term "through the air" can be used for infectious diseases in which the main spread involves a pathogen traveling through the air or being suspended in the air. The experts said this is similar to the official description of "waterborne" diseases.
该文件称，“通过空气”一词可用于主要传播涉及病原体通过空气传播或悬浮在空气中的传染病。 专家表示，这与官方对“水传播”疾病的描述类似。
The WHO’s new explanation is an effort to avoid public misunderstandings about how some diseases can be passed through the air or are “airborne.”
世界卫生组织的新解释是为了避免公众对某些疾病如何通过空气传播或“空气传播”产生误解。
Such misunderstandings happened during the COVID-19 pandemic. The WHO was criticized by many scientists during the early days of COVID-19 in 2020. They accused the U.N. health agency of failing to warn the public early on that the virus could spread through the air.
此类误解在 COVID-19 大流行期间发生过。 2020 年 COVID-19 爆发初期，世界卫生组织受到许多科学家的批评。他们指责联合国卫生机构未能及早警告公众该病毒可能通过空气传播。
The scientists said this led to too much public guidance centered on handwashing and similar measures to prevent the spread of COVID-19. They said this guidance ignored other measures, such as looking at the spread of viruses through ventilation systems.
科学家们表示，这导致了太多以洗手和类似措施为中心的公共指导，以防止 COVID-19 的传播。 他们表示，该指南忽略了其他措施，例如观察病毒通过通风系统的传播。
By July 2020, the agency said there was "evidence emerging" of airborne spread. Soumya Swaminathan was WHO chief scientist during the start of the COVID-19 pandemic. Swaminathan began a process to agree on a new definition for airborne disease spread. She later said she thinks the agency should have been more forceful in that message "much earlier."
该机构表示，到 2020 年 7 月，“有证据表明”空气传播。 Soumya Swaminathan 在新冠肺炎 (COVID-19) 大流行初期担任世卫组织首席科学家。 斯瓦米纳坦开始就空气传播疾病传播的新定义达成一致。 她后来说，她认为该机构应该“更早”更强有力地传达这一信息。
Swaminathan’s successor, Jeremy Farrar, recently told Reuters news agency the new definition was about more than COVID-19. He added that at the beginning of the pandemic there was a lack of available evidence. He said experts including the WHO had acted in "good faith." At the time, he headed the Wellcome Trust charity and advised the British government on COVID-19.
斯瓦米纳坦的继任者杰里米·法勒 (Jeremy Farrar) 最近告诉路透社，新定义不仅仅涉及 COVID-19。 他补充说，在大流行开始时，缺乏可用的证据。 他说，包括世界卫生组织在内的专家都是本着“善意”行事的。 当时，他是 Wellcome Trust 慈善机构的负责人，并就 COVID-19 向英国政府提供建议。
Farrar said the new definition would permit discussions to begin about issues such as ventilation in different kinds of buildings including hospitals and schools. He compared the issue to the realization that blood-borne viruses, like HIV or hepatitis B, could be spread by medics not wearing gloves.
法勒表示，新的定义将允许开始讨论医院和学校等不同类型建筑的通风等问题。 他将这个问题与认识到艾滋病毒或乙型肝炎等血源性病毒可能由不戴手套的医务人员传播的认识进行了比较。
"When I started out, medical students, nurses, doctors, none of us wore gloves to take blood," Farrar said. "Now it is unthinkable that you wouldn’t wear gloves. But that came because everyone agreed on what the issue was, they agreed on the terminology… [The change, in practice,] came later," he added.
“当我刚开始时，医学生、护士、医生，我们都没有戴手套来采血，”法勒说。 “现在，你不戴手套是不可想象的。但这是因为每个人都同意问题是什么，他们就术语达成一致……[实际上，变化]是后来发生的，”他补充道。
