冬日私语
阿西尼博因山坐落在不列颠哥伦比亚省的原始荒野中，与周围的省级公园形成了一个迷人的“高山仙境”。图中这座雄伟的山峰又被称作“落基山脉的马特洪峰”，其海拔高达3618米，以其粗犷雄伟的气势而备受瞩目。“阿西尼博因”这个名字是为了向曾经居住在这里的原住民阿西尼博因人致敬。据悉，阿西尼博因山省级公园是受保护区域，其占地面积超3.9万公顷，为探险者们提供了迷人壮丽景观。在这片荒野上，你还能邂逅不少野生动物，比如灰熊、美洲狮、山羊等。此外，网状般的小径遍布园区，也为游客们提供了便利。沿着小径行走，你可以在公园里徒步旅行、滑雪、露营。在大山的庇护下，这座公园体现了加拿大落基山脉中心地带的自然原始之美的精髓。

水上明镜 Mirror, mirror, on the water
内格罗河起源于哥伦比亚，是亚马逊河的支流之一。在西班牙语中，
内格罗河（Río
Negro）的意思是“黑色的河”，因为从远处看它，河水是黑色的。但走进观看，其河面平静如镜，就如图中所展示的那样，可以倒映出蔚蓝的天空以及彩虹的颜色。内格罗河的河水之所以是黑色的，是因为附近沼泽中渗出了有机物分解时产生的高浓度腐殖酸。作为亚马逊河北岸最大的支流之一，内格罗河在复杂的亚马逊流域生态系统中发挥着至关重要的作用。它也是许多动植物的家园，比如极度濒危的黑白柽柳猴、巴西巨獭以及近700种鱼类。
From its source in Colombia, the Río Negro flows about 1,400 miles to become one of the largest tributaries of the Amazon River at the Meeting of Waters in Manaus, Brazil. It is also the largest blackwater river in the world, its water stained by decomposing organic matter that seeps in from swamps. These slow-moving, dark waters beautifully reflect the colors of the sky, including the rainbows which form over the Amazon basin, as seen here. The river also plays a crucial role in the ecosystem, as the home of many plants and animals, including the critically endangered Brazilian barefaced tamarin, the giant river otter, and nearly 700 species of fish.

永恒之城托莱多 Toledo's timeless tale
托莱多是位于西班牙卡斯蒂利亚-拉曼恰地区的一座城市，因其独特的地理位置而闻名。托莱多位于一块凸起的高地上，三面被塔古斯河环抱。这座辉煌的城市在中世纪被称为“三文化之城”，基督教、穆斯林和犹太教在这里和谐共处。自1986年起，托莱多就被联合国教科文组织列为世界文化遗产，其历史核心区有许多清真寺、犹太教堂以及令人印象深刻的哥特式大教堂。在八世纪左右，摩尔人来到了这个地方，他们留下的摩尔人文化对这座城市产生了深远的影响。16世纪以前，托莱多的铸剑工艺闻名欧洲。16世纪时，画家埃尔·格列柯曾在这座城市居住，并对该地产生了深刻的影响。在此期间，埃尔·格列柯创作了一些极其重要的作品，如《圣母蒙召升天》，这一画作被视为他最伟大的杰作之一。
Built on a hill and surrounded on three sides by the Tagus River, the Spanish city of Toledo is a UNESCO World Heritage Site packed with history. Its towering Alcázar fortress and impressive Gothic cathedral dominate the skyline, but the city is also home to mosques and synagogues. Toledo bears strong cultural influences from the Moors, who ruled here for centuries, following their arrival in Spain in 711. It was known as the City of the Three Cultures during the Middle Ages, when its Christian, Muslim, and Jewish communities coexisted harmoniously. Toledo has been the home of sword making since Roman times and is also famous for its marzipan. In the 16th century, the city was home to the famous painter El Greco, who was inspired to create some of his greatest masterpieces here.

不一样的热带雨林 A different kind of rainforest
想象一下，你可以花一天时间在森林里徒步，沉浸在郁郁葱葱的绿色空间中，而不是疯狂地检查节假日购物清单上的一件件商品。欢迎来到“绿色星期五”！它是“黑色星期五”的环保替代品，创立于2015年。在“绿色星期五”，我们鼓励人们在购物时做出更加理智的选择，拥抱大自然，拒绝冲动性消费。因此，请在这个绿色星期五让自己暂停片刻，投入大自然的怀抱吧！
奥林匹克国家公园的苔藓长廊位于华盛顿州的霍河雨林。这片雨林不同于大多数人印象中的热带雨林，它有一条短暂但迷人的环形幽径，是各类苔藓的家园，这些苔藓优雅地覆盖在雄伟的云杉和铁杉上。去这里前请记得带件外套，因为这片森林是美国本土最潮湿的地方，年降雨量接近130英寸。难怪这里如此绿意盎然！
Imagine spending the day hiking amid these moss-covered trees instead of frantically checking items off your holiday shopping list. Welcome to Green Friday, the environmental alternative to Black Friday. The aim is to encourage people to make ethical shopping choices—or to refrain from shopping altogether and embrace nature instead.
A good place to start is the Hall of Mosses at Olympic National Park, in Washington's Hoh Rain Forest. This fantastical landscape is a temperate rainforest with an enchanting loop trail through mosses gracefully draped over majestic spruces and hemlocks. Bring a jacket though; this forest is the wettest in the contiguous United States with an annual rainfall of nearly 130 inches. No wonder it's so green!

从深海到天空 From the depths to the skies!
雄伟的泰德峰海拔3718米，耸立在加那利群岛上。这座火山从海底隆起的高度达到了惊人的7500米，因此它既是西班牙最高的山峰，也是世界上海拔第三高的火山。
这个多姿多彩的地方曾是多部著名电影的拍摄地，包括《速度与激情》（2001年）、《第一滴血5：最后的血》（2018年）和《诸神之战》（2010年）。泰德国家公园占地189.90平方公里，已被联合国教科文组织认定为世界遗产。这里还拥有丰富的动植物资源。因此，如果您计划游览这个神奇的地方，请务必穿上合适的鞋袜，备好美味的小吃，尽情享受这段旅程。
The majestic peak of Teide, at 3,715 meters above sea level, rises in the Canary archipelago. This volcano rises an impressive 7,500 meters from the ocean floor, making it the highest peak in Spain and the third-highest volcano in the world from the seabed.
This diverse location has served as the backdrop for several notable film productions, including "The Fast and The Furious" (2001), "Rambo V: Last Blood" (2018), and "Clash of the Titans" (2010). Teide National Park covers an area of 189.90 square kilometers and has been recognized as a UNESCO World Heritage Site. It is also home to a rich biodiversity of native flora and fauna. Therefore, if you plan to visit this amazing place, be sure to wear suitable footwear and prepare a delicious snack to make the most of the experience.

人少景美的静谧之地 Big on beauty, short on people
今天的图片让我们一睹大提顿国家公园的美景！该公园建于1929年，位于美国人口最少的怀俄明州，以壮丽连绵的雪山山峰而闻名。园区内高耸入云的巍峨雪山，与蜿蜒的蛇河、纯净的湖水以及丰富的野生动物共同构成了一幅美丽的画卷。去这里的时候，要记得带上你的双筒望远镜！如果是夏天，一定要观察叉角羚，它们可是长途跋涉了约150英里才来到这里。此外，麋鹿和野牛也是这里的夏季访客。这些动物的迁徙不仅有助于植物种子的传播，还为其他捕食者提供了食物，这对大提顿国家公园的生态系统起着至关重要的作用。
Today's image gives us a glimpse of beautiful Grand Teton National Park, in our least populous state, Wyoming. The park, established in 1929, encompasses lakes, the Snake River, and the Teton Range, famed for its series of sharp, jagged peaks. Bring your binoculars with you, and if it's summertime, be on the lookout for pronghorn, which travel about 150 miles to get there from Wyoming's Upper Green River Basin. They aren't the only creatures to visit seasonally; elk and bison are also summer visitors. These migrations play a vital role in the ecosystem of Grand Teton National Park. The animals help disperse seeds and are also food for predators.

童话城堡
科奇城堡坐落在威尔士的一座树木繁茂的山丘上，该城堡的名字在威尔士语中的意思是“红色城堡”，著名建筑师威廉·伯吉斯是它的设计师。这座城堡的内部装饰颇为奢华，犹如一首由繁复的雕刻工艺、鲜艳的彩色玻璃和奢华的家具交织而成的华丽交响乐。城堡的独特外形和维多利亚时期的内部设计充分展示了设计师的才华。其设计融合了中世纪的底蕴及19世纪的创新，被誉为英国哥特式复兴的典范。城堡的四周树林密布，从远处望去，宛若童话世界。这片山毛榉森林拥有丰富的植被，包括蝴蝶兰、燕窝兰和多年生山靛等稀有植物，具有特殊的科考价值，因而被保护起来了。

谨慎行事！ Tread carefully!
在爱沙尼亚的众多自然景观中，有一个建立于1994年的Alam-Pedja自然保护区。这片偶尔被冰雪覆盖的保护区位于塔尔图县，占地132平方英里，是爱沙尼亚最大的自然保护区。该保护区是由广袤的湿地、森林和河流组合而成的，还有尚未被开发的原始荒野。从稀有的白尾海雕到行踪难觅的黑鹳，这里有200多种鸟类。图上展示的是保护区那由水生森林织造而成的绮丽画卷：静水森林、沼泽森林和洪泛森林错落有致，细长的莎草植物点缀其间。此外，这里还有蜿蜒的小径和木板路吸引着探险家们来打造自己的冒险之旅。
Among Estonia's stunning natural sites is the Alam-Pedja Nature Reserve, covering 132 square miles of wilderness in the heart of the country. This occasionally ice-covered, vast area of wetlands, forests, and rivers is the largest natural reserve in Estonia. From the majestic white-tailed eagle to the elusive black stork, more than 200 bird species can be found here. The landscape is a tapestry of aquatic forests: still water, bog, and floodplain forests. Winding trails and boardwalks invite explorers to craft their own adventures.

该给靴子系上鞋带了！ Time to lace up those boots
朋友们，是时候系好登山靴，一起去徒步了！早在20世纪60年代，美国的林登·约翰逊总统就签署了《国家步道系统法案》，旨在保护、推广和开发美国各地的自然和历史资源。还在犹豫去哪里徒步旅行？这里有一个选择：就是图上这座位于威斯康星州的铜瀑布州立公园。从巴德河沿岸那长达17英里步道，到瀑布和古老的熔岩流，这个公园有很多值得一去的地方。无论是崎岖的山路，宁静的林间小道，还是海滨步道，这个国家总有一条步道适合你。但请记住，一定要尊重自然，遵循“不留痕迹”的原则，除了照片什么都别留下。祝你徒步旅行愉快!
Take a hike, buddy! No, not the 'get out of here' version but the 'get out there' version. It's time to lace up those boots and take advantage of our national trails, which span over 91,000 miles. Back in the 1960s, President Lyndon B. Johnson signed the National Trails System Act into law, to preserve, promote, and develop scenic and historic trails across the country. Can't decide where to start? Our homepage image offers up one option which is awash with fall colors—Copper Falls State Park in Wisconsin. With 17 miles of trails along the Bad River, past waterfalls and ancient lava flows, this park has a lot to offer. Whether it's a rugged mountain path, a serene forest walk, or an oceanside stroll, this country has a trail waiting for you. But remember to respect nature, follow 'leave no trace' principles, and take nothing but photographs. Happy hiking!

西方哲学的发源地 The birthplace of Western philosophy
值此世界哲学日之际，我们一起来了解一下希腊首都雅典。这座城市既是欧洲哲学的发源地，也是西方文明的摇篮，其标志性建筑雅典卫城和帕特农神庙让我们想起苏格拉底、柏拉图和亚里士多德的聪明才智。古希腊哲学注重批判性思维和质疑精神，希腊三贤掀起的理性革命，对当今社会仍有深远的影响。联合国教科文组织也通过庆祝世界哲学日，来彰显哲学对人类思想、文化和个人的深远影响。哲学是一门智慧学，今天就花点时间去领略哲学的奥秘吧！
On World Philosophy Day, we're in Athens, the capital of Greece, the birthplace of Western philosophy and democracy. The iconic Acropolis, the ancient citadel that towers over Athens, and its most famous monument, the Parthenon, remind us of the brilliant minds of Socrates, Plato, and Aristotle. Ancient Greek philosophy focused on critical thinking and questioning and started a revolution of rationale that is still shaping our society today. UNESCO recognizes the profound impact philosophy has on human thought, cultures, and individuals on World Philosophy Day. Take time today to discover the depths of the 'love of wisdom'!
