シャドーイング練習: What Is Life? Is Death Real? - 動画で英語スピーキングを学ぶ
レッスンを作成中...
1
Life is fundamentally different from dead stuff, or is it?
2
Physicist Erwin Schrödinger defined life this way.
3
Living things avoid decay into disorder and equilibrium.
4
What does this mean?
5
Let's pretend that your download folder is the universe.
6
It started orderly and got more and more chaotic over time.
7
By investing energy, you can create order and clean it up.
8
This is what living things do.
9
But what is life?
10
Every living thing on this planet is made of cells.
11
Basically, a cell is a protein -based robot too small to feel or experience anything.
12
It has the properties we just assigned to life.
13
It has a wall that separates it from the surroundings creating order.
14
It regulates itself and maintains a constant state.
15
It eats stuff to stay alive, it grows and develops, it reacts to the environment, and it's subject to evolution,
16
and it makes more of itself.
17
But of all the stuff that makes up a cell, no part is alive.
18
Stuff reacts chemically with other stuff, forming reactions that start other reactions, which start other reactions.
19
In a single cell, every second, several million chemical reactions take place, forming a complex orchestra.
20
A cell can build several thousand types of protein, some very simple, some complex micromachines.
21
Imagine driving a car at 100 km an hour
22
while constantly rebuilding every single part of it with stuff you collect from the street.
23
That is what cells do.
24
But no part of the cell is alive, everything is dead matter moved by the laws of the universe.
25
So is life the aggregate of all these reaction processes that are taking place?
26
Eventually, every living thing will die.
27
The goal of the whole process is to prevent this by producing new entities.
28
And by this, we mean DNA.
29
Life is, in a way, just a lot of stuff that carries genetic information around.
30
Every living thing is subject to evolution, and the DNA that develops the best living thing around it will stay in the game.
31
So, is DNA life then?
32
If you take DNA out of its hull, it certainly is a very complex molecule, but it can't do anything by itself.
33
This is where viruses make everything more complicated.
34
They are basically strings of RNA or DNA in a small hull and need cells to do something.
35
We're not sure if they count as living or dead.
36
And still, there are 225 million cubic meters of viruses on Earth.
37
They don't seem to care what we think of them.
38
There are even viruses that invade dead cells and reanimate them so they can be a host for them, which blurs the line even more. Or mitochondria.
39
They are the power plants of most complex cells and were previously free -living bacteria that entered a partnership with bigger cells.
40
They still have their own DNA and can multiply on their own, but they are not alive anymore they are dead
41
so they traded their own life for the survival of their DNA
42
which means living things can evolve into dead things as long as it's beneficial to their genetic code
43
so maybe life is information that manages to ensure its continued existence
44
but what about AI artificial intelligence by our most common definitions we are very close to creating artificial life in computers
45
It's just a question of time before the technology we build gets there.
46
And this is not science fiction either.
47
There are a lot of smart people actively working on this.
48
You could already argue that computer viruses are alive.
49
Hmm, okay, so what is life then?
50
Things?
51
Processes?
52
DNA?
53
Information?
54
This got confusing very fast.
55
One thing is for sure, the idea that life is fundamentally different from non -living things
56
because they contain some non -physical element or are governed by different principles than inanimate objects turns out to be wrong.
57
Before Charles Darwin, humans drew a line between themselves and the rest of living things.
58
There was something magical about us that made us special.
59
Once we had to accept we are, like every living being, a product of evolution, we drew a different line.
60
But the more we learn about what computers can do and how life works, the closer we get to creating the first machine that fits our description of life,
61
the more our image of ourselves is in danger again.
62
And this will happen sooner or later.
63
and here's another question for you
64
if everything in the universe is made of the same stuff does this mean everything in the universe is dead
65
or that everything in the universe is alive
66
that it's just a question of complexity does this mean we can never die
67
because we were never alive in the first place is life
68
and death an irrelevant question
69
and we haven't noticed it yet is it possible we are
70
much more part of the universe around us than we thought
71
don't look at us we We don't have any answers for you, just questions for you to think about.
72
After all, it's thinking about questions like this that makes us feel alive and gives us some comfort.

シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
