쉐도잉 연습: Elements | Middle school chemistry | Khan Academy - 영상으로 영어 말하기 배우기
레슨 만드는 중...
1
Think about all the thousands of books and poems and articles and dictionaries and encyclopedias and textbooks and so much more.
2
All those English writings are fundamentally made of what?
3
26 letters.
4
And yeah, some spaces, but that's it.
5
These 26 letters forms the building block of almost every single thing, all the uncountable words and sentences that you can make.
6
Now, guess what?
7
Turns out, our nature is similar.
8
Almost everything that you can touch and taste and smell
9
and feel around you from the germs to microbes to stuff like cats
10
and dogs to oceans and mountains and even planets and stars.
11
Turns out, All of these are also made from just a few building blocks, about a hundred of them.
12
Each square over here represents a building block, and we'll talk a little bit about how we arrange them and stuff.
13
But these building blocks are called the elements.
14
And that's what we're going to talk about in this video.
15
So let's do that.
16
First of all, these elements, the building blocks, are also called pure substances.
17
And like I said earlier, they make up almost all the matter around us.
18
hydrogen and oxygen and consider any living being like yourself then you are mostly made of six Elements.
19
Oxygen, Carbon, Hydrogen, Nitrogen, Calcium, and Phosphorus.
20
I mean, there are other elements, but these mostly make it up.
21
And just to give you another example, if you consider any rock, then they're mostly made of five elements: Silicon,
22
Oxygen, Aluminium, Magnesium, and Iron.
23
Don't worry about remembering the names of these elements for now.
24
What's important, and I keep repeating because it's so important, is that almost all the matter in the universe is made from these elements.
25
So to study matter, we need to study these elements.
26
So let's do that.
27
We arrange these elements in this particular form and we call this the periodic table.
28
It might seem daunting at first, but let's look at it, okay?
29
So first of all, you can see that each element gets a square and a number.
30
So, element number one is hydrogen.
31
Element number two is over here, helium.
32
Element number three is lithium.
33
Element number four is beryllium and so on and so forth.
34
What we want to notice over here is that each element has a symbol, kind of an abbreviation.
35
Now for some elements, that's basically the first letter of the word, H for hydrogen.
36
B for boron, C for carbon, N for nitrogen, and so on and so forth.
37
And notice we always use capital letters.
38
But what about other elements which start with the same letter?
39
For example, helium.
40
How do we ensure we don't confuse it with hydrogen?
41
Well, we use first two letters, so HE.
42
Similarly, for calcium, to make sure we don't confuse it with carbon, we use the first two letters, CA, and so on and so forth.
43
But what's important again over here is to notice how we write that.
44
the first letter is capital over here, the second letter is small.
45
So we'll never write helium this way, where both are capital, and we'll never write it this way, where both are small.
46
We'll always write it as first letter capital, second letter small, and that's always the case.
47
Alright, these make sense, but what about sodium?
48
Sodium is Na, what's going on over here?
49
And then there's more such stuff.
50
So for example, gold is Au.
51
Tungsten, which is used in the filament of our bulbs, is W.
52
And lead is PB, what's going on over here?
53
Well, humanity has known about these elements for a long time now.
54
And some of these symbols are taken from the old names from different languages like Greek, Latin, Arabic, German, and so on.
55
Na stands for natrium, a Latin word for sodium.
56
AU comes from Aurum.
57
PB comes from Plumbum, the Latin word for lead.
58
Fun fact, earlier pipes in the Roman Empire were made from lead
59
and therefore people who used to fix those pipes were called Plumbers and the name is stuck today.
60
And W comes from the German Wolfram.
61
Now again, you might be thinking, "Oh my god, how am I supposed to remember all of this?" Don't worry, we don't have to do that.
62
As we start talking about some of the common elements over and over again, we'll start So, in summary, all the matter that you see,
63
almost everything in the universe is made of a few, about a hundred elements, which we also call the pure substances.
64
They're arranged this way in what we call the periodic table.
65
And just like how learning the English language is basically figuring
66
out how we can combine these different letters to form very interesting words and sentences,
67
the trick to learning about matter is learning how we can combine these different elements to form interesting new things.
68
before?
69
Well, imagine we had a hundred different kinds of Legos with us.
70
Then by combining them in different combinations, you can build up almost anything you want.
71
And now you can imagine some of these Lego structures are like mountains and others are like cats.
72
And we can build whatever we want.
73
We can let our imagination lose over here, which is pretty awesome.
74
But if you break them all down into their basic pieces, you get back your elements.

맥락 및 배경
영어를 배우는 과정에서, 많은 사람들이 화학 같은 복잡한 주제를 접하게 됩니다. 이 비디오에서는 물질을 구성하는 기본적인 요소인 '원소'에 대해 설명하고 있습니다. 영어의 26자와 같이, 원소는 우리가 주변에서 접하는 모든 물질의 기본 구성 요소입니다. 이러한 원소들을 이해하는 것은 과학뿐 아니라 영어 회화 연습에도 중요한 기초가 됩니다. 따라서 이 비디오를 통해 화학적 개념을 익히고, 동시에 영어 실력을 향상시키는 기회를 제공하고자 합니다.
일상적인 의사소통을 위한 5가지 표현
- “이것은 무엇으로 만들어졌나요?” - 주제를 시작할 때 유용한 질문입니다.
- “주변에 있는 물질들을 생각해보세요.” - 생각을 자극하는 명령형 표현입니다.
- “이 원소들은 대부분 이러한 기본 구성 요소로 이루어져 있습니다.” - 설명을 할 때 활용할 수 있는 문장입니다.
- “원소의 기호는 항상 첫 글자는 대문자로, 두 번째 글자는 소문자로 표기합니다.” - 규칙을 강조할 때 쓰는 표현입니다.
- “각 원소는 고유한 번호와 기호를 가지고 있습니다.” - 정보 전달에 유용한 문장입니다.
단계별 쉐도잉 가이드
이 비디오의 내용을 효과적으로 이해하고 자신의 영어 회화 능력을 향상시키기 위해서는 영어 쉐도잉 기법이 매우 유용합니다. 아래 단계를 따라 진행해 보세요:
- 1단계: 비디오를 처음 시청하며 전체적인 내용을 파악합니다. 기본 개념에 대한 이해가 선행되어야 합니다.
- 2단계: 비디오를 일시 정지하고 짧은 구문을 반복적으로 듣습니다. 예를 들어, “이 원소들은 대부분 이러한 기본 구성 요소로 이루어져 있습니다.”와 같은 구문을 반복하며 발음을 익힙니다.
- 3단계: 쉐도잉 연습 시, 원문의 발음과 억양에 맞춰 소리 내어 따라 해보세요. 이 과정에서 문장 외운 후 대화 중 활용할 수 있습니다.
- 4단계: 직접 일상 대화에서 배운 표현을 사용해 보세요. 친구와의 대화, 또는 자신에게 질문을 던지는 연습을 통해 활용합니다.
- 5단계: 자신의 목소리를 녹음하여 들어보고, 발음과 억양을 개선할 수 있는 부분을 체크합니다. 이를 통해 shadow speech 능력이 향상됩니다.
이러한 단계를 통해 비디오에서 학습한 내용을 실행에 옮기고, IELTS 스피킹 준비 및 유튜브 영어 공부에 큰 도움이 될 것입니다. 지속적인 연습이 필요하며, 모든 과정에서 즐거움을 느끼는 것이 중요합니다.

| 관계절 who / which + 절 — 사람이나 사물에 대한 추가 정보 | Tungsten, which is · people who used · here, which is |
| “might / may” 가능성 might/may + 동사 — 가능하지만 확실하지 않은 일 | might seem · might be |
| 동사 + -ing enjoy, keep, stop… + -ing — 뒤에 -ing형이 오는 동사 | keep repeating · start talking |
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.
