每日口說挑戰【TED-Ed】雪花的科學 (The science of snowflakes - Maruša Bradač)

★My Thoughts★
從這影片讓我由衷敬佩學習化學的朋友們，一堆化學分子讓我頭腦好暈唷 (ఠ్ఠ ˓̭ ఠ్ఠ)，但是我學到了雪花片是「氣體直接變成固體」!

★影片重點句子★
When water freezes, this bonding occurs on repeat, ultimately forming a hexagonal structure due to the angle between hydrogens and oxygen within each molecule.
當水結凍時，氫鍵不斷生成，最後形成六邊形的結構，這是由每個水分子中氫原子和氧原子所夾的角度所造成。

As the snowflake moves through the air, water vapor molecules stick to the six sharp edges and expand the snowflake outwards, bit by bit.
當雪花飄在空氣之中時，水蒸氣會依附在六邊形的邊緣，一點一點的逐漸增加雪花的體積。

A snowflake's developing shape depends on atmospheric conditions, like humidity and temperature.
雪花最終的形狀取決於大氣的狀態，像是濕度以及溫度等。

So what's happening is that as skis move, they rub the surface of the snow and warm it up, creating a thin layer of water, which helps them slide along.
那麼，滑雪時究竟發生了些什麼事呢？滑雪板與雪面相互摩擦並產生熱，融出了一層水來幫助滑雪板前進。

So technically, it's not really snow skiing, but water skiing.
因此，嚴格來說，這其實不是在滑雪而是在滑水。

What’s up, VoiceTubers? Leila here. Have you ever heard that no two snowflakes are alike? I mean, they may look like tiny pieces of fluffy ice, but at a microscopic level, they are each different. How can that be? Well, today’s video dives into the physics behind snowflakes, how they form, why they always have six sides, and how they each form differently. If that sounds like a boring science lesson, don’t worry, it isn’t. The animation for the video makes it way easier to understand. Plus there’s skiing and the abominable snowman and...well, I guess you’d better just check out the video for yourself, if you haven’t already.


In the meantime, let’s get to the Sentence of the Day:

You could say a snowflake is simply frozen water, but compare one with an ice cube from the freezer, and you'll realize they're very different things.
當然你可以說雪花不過是結凍的水，但與冷凍庫中的冰塊相比，你會發現雪花其實是非常不一樣的東西。

Vocabulary:

1. compare (v.) KK: /kəmˋpɛr/ IPA: /kəmˈper/
to examine or look for the difference between two or more things
對比，對照，比較
It takes me a while to go shopping because I always compare prices.
​​我買東西都需要花上一些時間，因為我總是會比較價格。


2. realize (v.) KK: /ˋrɪə͵laɪz/ IPA: /ˈriː.ə.laɪz/
to understand a situation, sometimes suddenly
明白；認識到；意識到
Oh, excuse me! I didn’t realize that was your umbrella.
不好意思！我不知道那是你的雨傘。


3. freezer (n.) KK: /ˋfrizɚ/ IPA: /ˈfriː.zɚ/
a container, operated by electricity, that stores food at a very cold temperature so that it becomes solid and can be kept safely for a long time
冷凍櫃；冰櫃

I remember when a friend taught me how to ski. After I got the basics down and could actually ski down an easy slope, my friend told me that the snow would feel different depending on the day and the weather.

“Huh? Isn’t snow just snow?”
“No way. There’s wet snow, there’s dry snow, there’s sticky snow, there’s slush snow--and the best kind is powder!”
“Huh?”

It took me a while, but after more experience, I got better at skiing and at recognizing the differences in snow conditions. I’m no expert when it comes to snow, but after watching today’s video, I have more of an appreciation for snow and I can better understand why it affects my skiing the way that it does. It’s like there was this whole mysterious world of snow that I knew nothing about--all these rules or recipes for making firm snow or hardpack snow. (Sigh) But I still haven’t had the chance to ski on powder.

Does it snow a lot where you live? Or have you never seen snow before? Let me know in the comments. And as always, hit that record button when you’re ready with your sentence. Catch ya next time.

今天好像是炒作出來的購物節？

You could say a snowflake is simply frozen water, but compare one with an ice cube from the freezer, and you'll realize they're very different things.

#今天的主題恰恰好適合今天的低溫
You could say a snowflake(/ˈsnoʊ.fleɪk/雪花n.) is simply(僅僅adv.) frozen(/ˈfroʊ.zən/結凍的) water, but compare(/kəmˈper/比較v.) one with an ice cube(/kjuːb/立方體) from the freezer(/ˈfriː.zɚ/冷凍櫃), and you'll realize(認識到) they're very different things.
你可以說雪花只不過是結凍的水，但與冷凍庫中的冰塊相比，你會發現它們其實是不一樣的東西。

What’s up, VoiceTubers? Leila here. Have you ever heard that no two snowflakes are alike(相似的)? I mean, they may look like tiny pieces of fluffy(蓬鬆的) ice, but at a microscopic(/ˌmaɪ.krəˈskɑː.pɪk/需要用顯微鏡才可看見的) level, they are each(每一個adv.) different. How can that be? Well, today’s video dives into the physics(/ˈfɪz.ɪks/物理學) behind snowflakes, how they form, why they always have six sides, and how they each(每一個deter.) form differently. If that sounds like a boring science lesson, don’t worry, it isn’t. The animation(動畫) for the video makes it way easier to understand. Plus there’s skiing and the abominable(/əˈbɑː.mə.nə.bəl/極惡的) snowman(雪人,傳說生物) and...well, I guess you’d better just check out the video for yourself, if you haven’t already. In the meantime, let’s get to the Sentence of the Day.

◆ abominable /əˈbɑː.mə.nə.bəl/ (adj.) 極壞的；惡劣的；可惡的；討厭的 very bad or unpleasant:
The prisoners are forced to live in abominable conditions. 犯人被迫生活在惡劣的環境中。

1. compare (v.) /kəmˈper/ 對比，對照，比較 to examine or look for the difference between two or more things:

“No way. There’s wet snow, there’s dry snow, there’s sticky snow, there’s slush(/slʌʃ/雪水) snow--and the best kind is powder!”
“Huh?”

It took me a while, but after more experience, I got better at skiing and at recognizing(識別) the differences in snow conditions. I’m no expert when it comes to snow, but after watching today’s video, I have more of an appreciation(感激n.) for snow and I can better understand why it affects my skiing the way that it does. It’s like there was this whole mysterious world of snow that I knew nothing about--all these rules or recipes(/ˈres.ə.pi/烹飪法) for making firm(堅固的) snow or hardpack(硬裝) snow. (Sigh) But I still haven’t had the chance to ski on powder. Does it snow a lot where you live? Or have you never seen snow before?

冷到想直接寒假@(￣-￣)@

當然你可以說雪花不過是結凍的水，但如果拿它和冷凍庫裡的冰塊相比，你就會發現兩者其實很不一樣。
