쉐도잉 연습: Candy Corn In Space - 영상으로 영어 말하기 배우기
레슨 만드는 중...
1
When astronauts go up in space, they're allowed to bring some special items.
2
Some astronauts fly M&Ms, some people fly beef jerky.
3
Don Pettit, this guy, chose candy corn.
4
He's a NASA astronaut who spent nearly half a year floating around the International Space Station.
5
And while he was up in space...
6
I elected to spend my off-duty time doing science of my own design.
7
this zero gravity candy corn demonstration.
8
It's a macroscopic analogy to how a surfactant molecule works.
9
And a surfactant molecule just means...
10
Soap.
11
So in this demo, a candy corn is equivalent to a soap molecule.
12
And this water blob represents grease or oil.
13
And basically the demo shows how soap cleans grease.
14
Soap molecules have a water loving end...
15
So they call that hydrophilic...
16
And a water water-hating end.
17
Hydrophobic.
18
And that's important.
19
Say you have a blob of oil and you throw it in a washing machine, the hydrophobic part of the molecule sticks into the grease and the oil,
20
and the hydrophilic part pokes up into the water.
21
In candy corn, the hydrophobic, hydrophilic sides are reversed.
22
This part is water-loving, and Pettit coated this side with oil to make it water-hating.
23
But the principle is the same.
24
The molecules or the candy corn arrange themselves around the glob based on attraction or repulsion to water.
25
Of course, that's how your clothes get clean.
26
You cover them with these hydrophilic, hydrophobic molecules called soap.
27
And once the soap molecules fully cover the grease blob, it becomes water-soluble.
28
It's called the critical micelle concentration.
29
Or in candy corn.
30
The critical candy corn concentration.
31
Once it hits this concentration.
32
All the dirt and the oil and the grease floats off of your fabric, and it mixes with the water, and then you pour the water off, and you're left with clean clothes.
33
Now in candy corn, there's a bonus science lesson.
34
After you reach the critical candy corn concentration, And a most amazing thing happens.
35
The blob goes from smushy to rigid.
36
You can think of it like...
37
Of putting the keystone in a Roman arch, where now all of a sudden gravity locks all the stones together, and you have this rigid arch that you could drive traffic across.
38
But we're in space, so it's not gravity at work.
39
It's surface tension holding the ball together.
40
This was one of many experiments Pettit did in space, but it's the only one that used candy corn.
41
I used our whole crew's supply of candy corn for this one demonstration, which I profusely apologized to the rest of the crew because they didn't get to eat any.
42
For Science Friday, I'm Flora Lichtman.
43
you

이 영상으로 연습하는 방법
- 먼저 말하지 않고 영상을 끝까지 듣고 모르는 단어를 적어 둡니다.
- 0.75배속으로 한 문장씩 섀도잉을 시작하고, 익숙해지면 보통 속도로 돌아갑니다.
- 자신의 목소리를 녹음해 원본과 비교하고, candy, molecule, soap 같은 단어에 특히 주의합니다.
쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법
쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
