在这个清爽的十月早晨，你过得怎么样，亨利？
I am doing exceptionally well, Ava.
我过得异常好，艾娃。
The air is crisp, and we have an absolutely stellar lineup of news stories today.
空气很清新，我们今天有一套绝对一流的新闻阵容。
We will be exploring some vital environmental science, breaking down complex global economic
我们将探索一些至关重要的环境科学，将复杂的全球经济
policies into plain English, and wrapping up with some mind -boggling discoveries from the worlds of
政策转化为浅显易懂的英语，并以来自...世界的令人匪夷所思的发现来结束。
history and biology.
历史和生物学。
Now that is what I call a well -balanced information diet.
这正是我所说的营养均衡的信息饮食。
Before we jump in, what are the quick headlines we are looking at today?
在我们深入探讨之前，我们今天关注的快速头条新闻是什么？
Our headlines start with a stark environmental warning.
我们的头条新闻从一个严峻的环境警告开始。
Next, we look at global trade, where Brazilian beef exports have hit a regulatory wall in China,
接下来，我们看看全球贸易，巴西牛肉出口在中国遭遇了监管墙，
triggering a heavy 55 % tariff.
引发了高达 55% 的沉重关税。
After that, we travel back in time to explore a medieval castle that has been found hiding in plain sight.
在那之后，我们穿越回过去，探索一座被发现隐藏在眼皮底下的中世纪城堡。
And finally, we will discover how butterflies use advanced optical illusions to escape hungry predators. Fascinating.
最后，我们将发现蝴蝶如何利用先进的视觉幻象来逃避饥饿的捕食者。太迷人了。
From the health of our entire planet to a tiny butterfly wing.
从我们整个星球的健康到一个小小的蝴蝶翅膀。
I am completely hooked and ready to learn.
我完全被迷住了，准备好学习了。
Let us start with the big story, Henry.
让我们从大故事开始，亨利。
Let us begin with our main scientific feature.
让我们从我们的主要科学专题开始。
A coalition of international scientists has issued their starkest warning yet regarding the physical
国际科学家联盟就...发出了迄今为止最严厉的警告
health of our planet.
我们星球的健康。
According to a comprehensive new report, seven out of the nine planetary boundaries that keep Earth
根据一份综合的新报告，保持地球...
habitable for humans have now been officially crossed.
人类宜居的九大行星边界中已有七个被正式越过了。
Hold on a second, Henry.
等一下，亨利。
Let us pause right there for our English learners.
让我们停在那里，为我们的英语学习者服务。
Planetary boundaries is a term we see quite often in science news.
行星边界是我们在科学新闻中经常看到的一个术语。
What does it actually mean in simple, everyday English?
它在简单、日常的英语中实际上是什么意思？
Think of our planet as a highly advanced spaceship.
把我们的星球想象成一艘高度先进的飞船。
And these nine boundaries are like the safety limits of the ship's vital systems.
而这九个边界就像是飞船至关重要的系统安全限制。
If the cabin temperature stays within a certain limit, the air recycler works, and the water system
如果客舱温度保持在一定限制内，空气循环器就能工作，水系统
is clean, the crew survives happily.
是干净的，船员就能快乐地生存。
But if you cross those limits, the spaceship starts to malfunction.
但如果你越过了这些限制，飞船就会开始发生故障。
These boundaries include things like climate change, biodiversity loss, freshwater availability, and
这些边界包括气候变化、生物多样性丧失、淡水可用性等，
land system changes.
土地系统变化。
Crossing seven of them means we are operating in a highly dangerous zone.
越过其中七个意味着我们正在一个高度危险的地带运作。
Oh, that is a perfect metaphor.
哦，这是一个完美的隐喻。
It is like ignoring seven different warning lights flashing red on the dashboard of our car.
这就像忽略我们汽车仪表盘上闪烁红光的七个不同的警告灯。
And I assume we are already seeing the real -world consequences of crossing these safety limits?
我猜我们已经看到了越过这些安全限制的现实世界后果？
We absolutely are.
我们绝对看到了。
Look at Switzerland, where glaciologists have reported another disastrous year of ice loss.
看看瑞士，那里的冰川学家报告了又一个灾难性的冰雪流失年。
Swiss glaciers have lost a staggering 5 % of their remaining volume after a summer of record -breaking
在经历了一个打破纪录的夏天后，瑞士冰川...
heat waves.
热浪。
Even more alarming?
更令人担忧的是什么？
Over the last five years alone, Switzerland has lost 20 % of its entire glacier ice.
仅仅在过去五年里，瑞士就失去了其全部冰川冰的20%。
20 % in just five years?
短短五年内就达到了20%？
That is one -fifth of their entire ice supply gone in the blink of an eye.
这是他们整个冰雪供应量转眼间就消失了五分之一。
That is not just a slow melt, Henry.
这不仅仅是一场缓慢的融化，亨利。
That is an absolute meltdown.
这是一场绝对的崩溃。
Why should someone living far away from Switzerland care about these melting glaciers?
为什么一个远离瑞士的人会关心这些融化的冰川？
Because glaciers are often referred to as the water towers of Europe.
因为冰川通常被称为欧洲的水塔。
During the spring and summer, they slowly melt and release fresh water into major river systems like
在春夏两季，它们慢慢融化并将淡水释放到主要河流系统中，比如
the Rhine and the Rhône.
莱茵河和罗讷河。
This water is absolutely essential for drinking, agriculture, cooling power plants, and keeping
这些水对于饮用、农业、冷却发电厂以及保持
major shipping lanes open.
主要航运通道畅通至关重要。
Without this steady glacial meltwater, Europe faces severe droughts, disrupted transport, and major
如果没有这源源不断的冰川融水，欧洲将面临严重的干旱、交通中断和重大
energy shortages. Wow.
能源短缺。哇。
So melting ice in the high Swiss mountains directly affects the food on people's tables and the
因此，瑞士高山上的冰川融化直接影响着人们餐桌上的食物和
electricity in their homes miles away.
数英里外他们家里的电。
It really shows how interconnected everything is. Exactly.
这确实表明一切都是多么紧密相连。
And the heat is not just affecting high altitudes.
而且高温不仅仅在影响高海拔地区。
It is deeply impacting our oceans as well.
它也正在深深地影响着我们的海洋。
Marine scientists have revealed that the world's oceans have absorbed an amount of record heat equal
海洋科学家透露，世界海洋吸收了创纪录的热量，其数量相当于
to 40 times the annual global energy consumption of humanity.
人类全年全球能源消耗量的40倍。
This has triggered intense marine heat waves, making seawater saltier and significantly more acidic.
这引发了强烈的海洋热浪，使海水 更咸且酸性显著增强。
Marine heat waves?
海洋热浪？
I suppose that is like an underwater desert expanding throughout the ocean.
我想这就好像是一个水下沙漠在整个海洋中扩张。
It must be devastating for marine life.
对海洋生物来说这一定是毁灭性的。
It is.
确实如此。
It disrupts entire ocean ecosystems, bleaching coral reefs and driving valuable fish stocks away
它破坏了整个海洋生态系统，导致珊瑚礁白化，并将有价值的鱼类种群驱赶
from their traditional habitats, which in turn threatens global fisheries and food security.
离开它们的传统栖息地，进而威胁到全球渔业和粮食安全。
It is a massive wake -up call for global climate action.
对全球气候行动来说是一个巨大的警钟。
It really is.
确实如此。
We need to start treating our spaceship with a lot more respect.
我们需要开始以更多的尊重来对待我们的飞船。
Now, let us shift gears and look at our second story, which takes us into the world of global
现在，让我们转换方向，来看看我们的第二个故事，它将带我们进入全球
economics and trade.
经济与贸易的世界。
What is happening with the beef trade between Brazil and China?
巴西和中国之间的牛肉贸易正在发生什么？
Indeed, a major economic development has occurred.
确实，发生了一个重大的经济发展。
Brazil's beef exporters have hit a financial wall in China.
巴西的牛肉出口商在中国碰壁了。
Starting this week, China has imposed a hefty 55 percent tariff on Brazilian beef imports after
从本周开始，中国对巴西牛肉进口征收了沉重的55%关税，此前
Brazil officially filled its low tax quota limit for the year.
巴西已正式填满了该年度的低税配额限制。
OK, Henry, let us break down the economic vocabulary here because international trade can get quite confusing.
好的，亨利，让我们在这里剖析一下经济词汇，因为国际贸易可能会让人非常困惑。
You mentioned two key terms, tariff and quota.
你提到了两个关键术语，关税和配额。
Can you explain these using a simple real world example?
你能用一个简单的现实世界例子来解释这些吗？
I would love to.
我很乐意。
Let us imagine you run a popular local movie theater.
让我们假设你经营着一家受欢迎的当地电影院。
To protect your regular snack bar, you make a rule about outside food.
为了保护你的常规小吃部，你制定了一条关于外带食物的规定。
You say, OK, customers can bring in up to one bag of popcorn for free.
你说，好的，顾客可以免费带入最多一袋爆米花。
That limit is your quota.
这个限制就是你的配额。
But if someone wants to bring in a second or third bag, they have to pay a $10 fee at the door.
但是如果有人想带第二袋或第三袋，他们必须在门口支付10美元的费用。
That extra fee is the tariff.
那笔额外的费用就是关税。
Oh, that makes complete sense.
哦，这完全讲得通。
So China has a quota system that allows a set amount of Brazilian beef to enter the country at a
所以中国有一个配额制度，允许一定数量的巴西牛肉以
very low tax rate.
非常低的税率进入该国。
But because Brazil exported so much beef so quickly this year, they filled up that limit.
但是因为巴西今年出口了太多的牛肉，以至于他们用满了那个额度。
And now any additional beef they send is subject to the high 55 percent tariff or the extra entry fee.
现在他们发送的任何额外牛肉都要缴纳高达百分之五十五的关税或额外的入场费。
Spot on, Ava.
完全正确，埃娃。
That is exactly how it works.
这正是它的运作方式。
Because the tariff makes Brazilian beef much more expensive to purchase, Chinese importers are
因为关税使得购买巴西牛肉的成本高得多，中国进口商们正在
looking at other options.
寻找其他选择。
This has opened a massive door for other major beef -producing nations like Argentina, Uruguay, and
这为阿根廷、乌拉圭等其他主要牛肉生产国打开了一扇巨大的大门，以及
Australia to increase their market share in China.
澳大利亚增加他们在中国的市场份额。
That is a classic economic shift.
这是一个典型的经济转变。
When one door closes, another opens for the competitors.
当一扇门关闭时，会为竞争对手打开另一扇门。
But does this mean Chinese consumers will see higher beef prices at their local supermarkets or
但这是否意味着中国消费者会在当地超市看到更高的牛肉价格，或者
hotpot restaurants?
火锅餐厅？
Not necessarily.
不一定。
Because the global beef market is highly competitive, other suppliers will likely step in quickly to
因为全球牛肉市场竞争非常激烈，其他供应商很可能会迅速介入以
keep the supply steady.
保持供应稳定。
However, it does mean that Brazilian beef companies will have to redirect their unsold meat to other
然而，这确实意味着巴西牛肉公司将不得不把他们未售出的肉转向其他
global markets, which could actually lower beef prices in other parts of the world as supply there increases.
全球市场，这实际上可能会降低世界其他地区的牛肉价格，因为那里的供应增加。
It is like a global game of musical chairs, but with steaks and burgers.
这就像一场全球音乐椅游戏，只不过用的是牛排和汉堡。
It is fascinating to see how trade rules can shift millions of tons of food around the globe in a
看到贸易规则如何在短短几天内将数百万吨食物转移到全球各地，真是令人着迷。
matter of days.
区区数天。
It certainly is.
确实如此。
Now, let us transition from the world of global trade to a truly wonderful historical mystery.
现在，让我们从全球贸易的世界过渡到一个真正精彩的历史谜团。
How would you feel if I told you that a giant, forgotten, medieval castle was discovered hiding in
如果我告诉你一座巨大的、被遗忘的中世纪城堡被发现藏在
plain sight?
显眼处？
I would say you have been reading too many adventure novels.
我会说你读了太多冒险小说。
Seriously, how do you lose a whole castle?
说真的，你怎么会弄丢一整座城堡？
It is not like misplacing your car keys.
这可不像是放错车钥匙。
You would be surprised.
你会感到惊讶的。
In Europe, a university professor has successfully identified the ruins of a lost medieval castle
在欧洲，一位大学教授成功地辨认出了一座失落的中世纪城堡的遗址
that had remained unnoticed for centuries despite being located in a heavily populated area.
尽管位于人口稠密的地区，但几个世纪以来一直未被注意到。
That is incredible.
这太不可思议了。
How did this professor manage to find it?
这位教授是怎么设法找到它的？
Did they use some kind of high -tech space satellite?
他们用了某种高科技太空卫星吗？
It was actually a combination of old -fashioned observation and modern digital mapping.
实际上这是老式观察和现代数字测绘的结合。
The professor was studying historical documents and noticed that the natural curves and bumps of a
这位教授当时正在研究历史文献，并注意到自然曲线和
grassy hill did not look entirely natural.
长满草的小山看起来并不完全自然。
They realized these were actually earthworks. Earthworks?
他们意识到这些实际上是土方工程。土方工程？
What are those?
那些是什么？
Earthworks are artificial banks of soil or stone created by ancient builders to serve as defensive
土方工程是古代建造者用泥土或石头建造的人工堤岸，用作防御
walls or foundations.
墙壁或地基。
Over hundreds of years, these structures get covered by grass, shrubs, and trees.
几百年来，这些结构被草、灌木和树木覆盖。
To the average person walking by, it just looks like a normal bumpy hill.
对于路过的普通人来说，它看起来就像一个普通的颠簸小山。
But if you look closely at the shape and layout, it reveals the precise outline of a defensive fortress. Wow.
但如果你仔细看形状和布局，它就会暴露出一个防御堡垒的精确轮廓。哇。
So nature basically grew a green camouflage blanket over a medieval fortress.
所以大自然基本上在中世纪堡垒上盖上了一层绿色的迷彩毯子。
People were probably walking their dogs over a king's castle every single day without having any
人们可能每天都在国王的城堡上遛狗，却完全
idea of what was beneath their feet. Exactly.
不知道他们脚下是什么。没错。
The professor used a technology called LIDAR, which stands for Light Detection and Ranging.
这位教授使用了一种叫做激光雷达的技术，代表光探测和测距。
It shoots rapid laser beams from an airplane down to the ground.
它从飞机上向地面发射快速激光束。
By measuring how long it takes for the light to bounce back, computers can map the ground in three
通过测量光线反弹所需的时间，计算机可以在三维中绘制地面地图
dimensions, digitally stripping away all the trees and grass to show the hidden structure underneath.
维度，数字剥离所有树木和草，以显示底层的隐藏结构。
This revealed a massive, complex castle layout with defensive ditches and a central tower.
这揭示了一个拥有防御性壕沟和中央塔楼的庞大且复杂的城堡布局。
LIDAR sounds like a real -life pair of X -ray glasses for archaeologists.
激光雷达听起来就像是现实生活中为考古学家准备的一副X射线眼镜。
It is amazing to think that even in our modern, crowded world, there are still grand historical
令人惊叹的是，即使在我们这个现代、拥挤的世界里，仍然有宏大的历史
secrets waiting to be uncovered right beneath our feet. Indeed.
秘密正等待着在我们脚下被发掘。的确如此。
It reminds us that history is not just in museums.
它提醒我们，历史不仅仅存在于博物馆中。
It is all around us.
它就在我们身边。
Now, let us move to our final, highly delightful story from the natural world.
现在，让我们转向来自自然世界的最后一个、非常令人愉悦的故事。
It involves a very common insect we all love, the butterfly.
它涉及我们都喜爱的非常普遍的一种昆虫——蝴蝶。
Ah, butterflies.
啊，蝴蝶。
Beautiful, delicate, and peaceful.
美丽、精致且宁静。
But how do they use optical illusions to survive, Henry?
但是，亨利，它们是如何利用光学错觉来生存的呢？
A groundbreaking study, published in the prestigious journal Nature, has revealed that the complex
一项具有突破性的研究发表在著名期刊《自然》上，表明其复杂性
patterns on butterfly wings are not just for display.
蝴蝶翅膀上的图案不仅仅是为了展示。
When a butterfly is in flight, the rapid flapping of its wings creates a powerful illusion of motion
当蝴蝶在飞行时，其翅膀的快速扇动会产生强烈的运动幻觉
that completely confuses the visual systems of predators, like birds.
这完全混淆了鸟类等捕食者的视觉系统。
Wait, an illusion of motion?
等等，运动错觉？
Is that like those optical illusions where a static image of circles seems to spin when you look at it? Precisely.
这就像那些当你看着它时，圆形的静态图像似乎在旋转的视错觉吗？正是如此。
When the butterfly flaps its wings, the contrasting light and dark patterns blend together in a
当蝴蝶扇动翅膀时，对比鲜明的光暗图案在一
fraction of a second.
瞬间之内融合在一起。
This trick makes the predator's brain believe that the butterfly is moving in a completely different
这种把戏让捕食者的大脑相信蝴蝶正朝一个完全不同的
direction, or flying much faster than its actual speed.
方向移动，或者飞得比其实际速度快得多。
That is brilliant.
真是绝妙。
So, when a hungry bird dives down to grab the butterfly, it aims for where it thinks the butterfly
所以，当一只饥饿的鸟俯冲下来抓蝴蝶时，它瞄准的是它认为蝴蝶
is going to be, but actually bites empty air. Exactly.
将要去的地方，但实际上却咬了个空。没错。
The bird misses the target, and the butterfly flutters away safely.
这只鸟错过了目标，而蝴蝶安全地振翅飞走了。
The researchers discovered that this visual trick is incredibly effective, especially in complex
研究人员发现，这种视觉把戏是极其有效的，尤其是在复杂的
forest environments where light and shadow are constantly shifting.
光影不断变化的森林环境中。
It is like a natural cloaking device.
这就像一个天然的隐形装置。
It shows us that evolution has turned these delicate little creatures into absolute master magicians.
它向我们表明，进化已经将这些脆弱的小生物变成了绝对的魔术大师。
What a fantastic way to wrap up our stories today.
这是为我们今天的故事做一个精彩总结的好方式。
Indeed, Ava.
确实如此，埃娃。
We have traveled from the urgent warning of our planet's boundary limits and melting glaciers to the
我们从关于地球边界限制和冰川融化的紧急警告，一路探讨到
intricate economic dance of international beef tariffs, explored a hidden castle camouflage, and
国际牛肉关税错综复杂的经济之舞，探索了一个隐藏的城堡伪装，并且
ended with the clever visual tricks of flying butterflies.
以会飞的蝴蝶巧妙的视觉把戏结束了今天的节目。
