We're training our eyes on the sky this Friday on CNN 10.

我們本週五在CNN10臺訓練我們的眼睛看天空。

I'm Carla Zeus.

我是卡拉-宙斯

Here's what's up.

這是怎麼回事。

This week, there were more than 400 reports of fire in the sky.

本週，天空中的火情報告有400多起。

There were mostly concentrated in and around Alberta, Canada, though the meteor was also visible in other parts of that country and in the U.

流星主要集中在加拿大阿爾伯塔省及其周邊地區，不過在該國其他地區和美國也能看到。

State of Montana, thanks in large part to surveillance in doorbell cameras, the American media or society received more than 100 videos of this.

蒙大拿州，很大程度上得益於門鈴攝像頭的監控，美國媒體或社會收到了100多段這樣的視頻。

The thing was so bright it was classified as a fireball, according to NASA.

根據美國宇航局的說法，這東西太亮了，被列為火球。

That means the rock could have been bigger than 3 ft in diameter.

這意味著這塊石頭的直徑可能大於3英尺。

It's a shocking celestial sight that looks really cool as long as it doesn't hurt anything.

這是一個震撼人心的天象，只要不傷害到任何東西，看起來就非常的酷。

And as far as we know it Didn't scientists believe it was just a meteor, not a meteorite?

而據我們所知，科學家們不是認為它只是一顆隕石，而不是隕石嗎？

What's the difference?

有什麼不同？

There are a lot of small rocks that air zinging through space.

有很多小石子，在空間裡空氣扎人。

They're called meteoroids.

他們被稱為流星體。

If one of these rocks hits the earth's atmosphere, it becomes a meteor that's also known as a shooting star.

如果其中一塊岩石撞上地球大氣層，就會變成一顆流星，也就是流星。

The streets you see across the sky are the result of Meteors burning up in our atmosphere, researchers say more than 90% of them burned up completely.

你在天空中看到的街道是流星在我們的大氣層中燃燒的結果，研究人員說90%以上的流星完全燃燒了。

If they don't do that, though, if part of the rocks survives its entry and smacks into the earth's surface, it's then classified as a meteorite.

如果他們不這樣做，不過，如果部分岩石在進入地球時倖存下來，並撞上了地球表面，那麼它就會被歸類為隕石。

Thousands of tiny meteorites strike the Earth every year.

每年都有成千上萬的小隕石撞擊地球。

But as far as we know, the one seen this week in Canada wasn't one of them.

但據我們所知，本週在加拿大看到的那個不是其中之一。

It's believed to have been a meteor.

它被認為是一顆隕石。

There haven't been any fragments reported from the Earth's surface.

還沒有任何關於地球表面碎片的報道。

Initially, scientists didn't know how big it was, how fast it was moving and what it was made of.

最初，科學家們並不知道它有多大，移動速度有多快，以及它是由什麼組成的。

But they're able to piece together some information about it, based on the multitude of different recordings taken from different cameras in different locations.

但他們能夠根據不同地點不同攝像頭拍攝的大量不同記錄，拼湊出一些相關資訊。

2028年的加州洛杉磯，而國際奧委會昨天剛剛宣佈，澳洲布里斯班是2032年夏季奧運會的首選舉辦地。

This is a new process for Olympic organizers.

這對奧運組織者來說是一個新的過程。

They haven't announced the venue for the 2030 Winter Games yet, and Brisbane is bid to host the 2032 games isn't a done deal.

他們還沒有公佈2030年冬季奧運會的舉辦地點，布里斯班申辦2032年奧運會也不是一錘定音。

The IOC still has to vote on this to make it final.

國際奧委會還需要進行表決，才能最終確定。

But because hosting the Olympics takes years to plan for and because of the uncertainty that still surrounds the 2020 Games which were delayed by the coronavirus pandemic, the committee's trying to devise a stable and predictable way to determine future host cities.

但由於舉辦奧運會需要多年的規劃，而且由於2020年奧運會因冠狀病毒大流行而被延後的不確定性仍然存在，委員會正試圖設計一種穩定和可預測的方式來確定未來的主辦城市。

從一個月後開始，火炬將開始為期121天的旅程，福島，然後穿過日本所有的縣福島是2011年東北大地震和海嘯期間造成核洩漏的重災區之一。

Now starting the relay in the region allows Japan the opportunity to highlight the reconstruction and recovery effort that has taken place since the devastating day nearly 10 years ago.

現在，在該地區啟動接力賽，使日本有機會突出強調自近10年前那個毀滅性的日子以來所進行的重建和恢復努力。

Now 10,000 torchbearers will take part in the relay and perhaps a sign of things to come during the Olympic and Paralympic Games summer mast.

Next stories about Eurasian beavers on the river Otter.

下一個故事是關於奧特河上的歐亞海狸。

Let's explain.

讓我們來解釋一下。

The otter is the name of a river in Devon, England, these wild Eurasian beavers or some of the first to live there in about 400 years.

水獺是英國德文郡一條河流的名字，這些野生的歐亞海狸或在400年左右的時間裡最先生活在那裡。

These animals were hunted to near extinction before the 20th century, in part because they were prized for their for used in felt hats.

在20世紀之前，這些動物被獵殺到幾乎滅絕，部分原因是它們被用於氈帽的珍貴。

But conservation efforts have helped the species recover, even though their relationship with people still isn't perfect.

但保護工作已經幫助該物種恢復，儘管它們與人的關係仍不完美。

What people didn't realize is how important beavers are to the landscape.

人們沒有意識到的是，河狸對景觀的重要性。

The dams they build, regulate water flow, increased biodiversity and even drive down pollution.

他們建造的水壩，調節了水流，增加了生物多樣性，甚至還降低了汙染。

In short, beavers are what are known as ecosystem engineers.

簡而言之，海狸就是所謂的生態系統工程師。

Beavers build dams and canals for their own protection.

海狸為了保護自己，修建了水壩和運河。

The dams raised the surrounding water, which helps them escape from predators.

水壩將周圍的水面抬高，這有助於它們躲避捕食者。

But wetting the landscape has a greater impact.

但溼化景觀的影響更大。

It also slows the water flow, reducing floods downstream in the wet season and drought in the dry season.

它還能減緩水流，減少下游雨季的洪水和旱季的乾旱。

Experts warn that areas like Devon are expected to Seymour flooding.

專家提醒，預計德文郡等地區將出現西摩洪水。

But a recent study on Beavers in England showed that their dams can reduce average floodwaters by up to 60%.

但最近一項關於英國海狸的研究表明，它們的水壩可以將平均洪水減少60%。

The organization behind reintroducing beavers to Devon is the Devon Wildlife Trust.

將海狸重新引入德文郡的背後組織是德文郡野生動物信託基金。

But before they released any beavers into the world, Ecologist ran a trial and how beavers might change the landscape.

但在他們將任何海狸放進世界之前，生態學家進行了一次試驗，以及海狸可能如何改變景觀。

So this is a three hectare enclosure that was built in 2010.

所以這是一個三公頃的圍牆，建於2010年。

What can you see?

你能看到什麼？

That's right, that's the damn there.

沒錯，就是那個該死的那裡。

That goes away across.

這就走了跨。

It's about 40 m long.

長約40米。

When we put them in here and started to see what they did to the watercourse, it was really profound, you know, we all suddenly became much more conscious of just how powerful this animal Waas the trust received permission to release beavers into the wild in 2015.

當我們把它們放在這裡，並開始看到它們對水道的影響時，真的很深遠，你知道，我們都突然變得更加意識到這種動物有多麼強大，華信在2015年獲得了將海狸釋放到野外的許可。

It was the first license in England to do so in the effect on the River Otter Basin.

這是英國第一張在奧特河流域效果的許可證。

Waas Dramatic.

華斯戲劇性。

This pond is being created by the Beavers, so they built a small dam that has increased the water level in this area that's enabled them to build a lodge on this island.

這個池塘是海狸族創造的，所以他們建了一個小水壩，增加了這一帶的水位，使他們能在這個島上建一個小屋。

Beaver lodges the home off beavers.

海狸住宿的家離海狸。

The entrance to the lodge is underwater right now.

山莊的入口現在在水下。

We've probably got the adult pair in this island, along with kits from this summer on the previous summer, so there might be eight beavers in that lodge right now.

我們在這個島上可能已經有了一對成年的海狸，還有上個夏天的工具包，所以現在那個小屋裡可能有八隻海狸。

There's also been a huge increase in biodiversity.

生物多樣性也有了很大的提高。

Is the wetland habitat attracts water?

溼地生境是否能吸引水？

Voles, otters, amphibians on birdlife.

田鼠、水獺、兩棲動物對鳥類動物。

But beavers can cause trouble.

但海狸會帶來麻煩。

For one, they're big beavers like pink tag can weigh up to 30 kg or £66.

首先，他們是大海狸，如粉紅色標籤可以重達30公斤或66英鎊。

That's quite a Big Dog.

那是一隻相當大的狗。

We've had fishermen telling us stories that they've been a bit scared Whilst fishing close to beavers.

我們有漁民告訴我們他們在靠近海狸捕魚時有點害怕的故事。

They also can waterlogged farm land and eat orchard trees.

它們還可以水淹農田，吃掉果園樹木。

So a big part of chanting Elliott's job is working with local landowners to make sure everyone is happy.

是以，誦讀埃利奧特的工作的一個重要部分是與當地的土地所有者合作，以確保每個人都滿意。

But overall, beavers are a huge benefit.

但總的來說，海狸是一個巨大的福利。

Ecosystems and society nations across Europe are working to restore them to their original range.

歐洲各地的生態系統和社會國家正在努力將它們恢復到原來的範圍。

It's being a hugely successful conservation story.

這是被一個巨大的成功的保護故事。

Beavers were reduced to around 1200 back in the 19 twenties, and now there are over a million beavers within Europe.

早在1920年代，河狸就減少到1200只左右，現在歐洲境內的河狸有100多萬隻。

我覺得你可以晉級，但你要和萊昂內爾-裡奇一起工作。

So this is what's being called a singing tiger.

所以這就是所謂的唱山虎。

He's an eight month old male cub in a Siberian zoo who is able to hit high notes that other tigers can't.

Officials say he's not in pain.

You're a cat of different stripes hitting high notes with your pipes on the prowl and Cajun meadow from the pitch of your falsetto.

你是一隻不同條紋的貓，用你的管子在徘徊中打出高音，從你的假聲的音調中打出卡瓊草原。
