The apple that shook the world.
0:00.96 – 0:02.58 (1.6s)
2
Can a falling fruit change how we see the stars?
0:02.58 – 0:05.94 (3.4s)
3
In 1666, Isaac Newton was a young man of 23, living in a small village called Woolsthorpe in England.
0:06.92 – 0:15.50 (8.6s)
4
The world was not calm.
0:16.58 – 0:18.16 (1.6s)
5
A terrible sickness, the great plague, had spread through cities like London.
0:18.16 – 0:22.98 (4.8s)
6
Schools closed, and people hid in their homes.
0:24.12 – 0:27.06 (2.9s)
7
Newton, a student at Cambridge University, had to leave his studies and return to his family's farm.
0:28.26 – 0:35.86 (7.6s)
8
The farm was quiet, with green fields, stone walls, and a big garden full of flowers and fruit trees.
0:37.40 – 0:45.12 (7.7s)
9
One warm summer afternoon, Newton sat under an apple tree in the garden.
0:46.66 – 0:51.36 (4.7s)
10
The tree was old, its branches heavy with red and green apples.
0:52.60 – 0:57.64 (5.0s)
11
The air smelled sweet, and bees buzzed around.
0:59.26 – 1:02.76 (3.5s)
12
Newton was not like other young men.
1:04.94 – 1:06.70 (1.8s)
13
He didn't care for games or gossip.
1:07.58 – 1:09.58 (2.0s)
14
His mind was always busy, chasing questions no one else asked.
1:10.78 – 1:15.60 (4.8s)
15
He wore a plain shirt and vest, his long hair tied back.
1:16.42 – 1:20.84 (4.4s)
16
In his hands was a notebook filled with strange drawings, circles, lines, and numbers.
1:21.38 – 1:29.94 (8.6s)
17
He loved math and science, but he felt stuck.
1:31.22 – 1:35.42 (4.2s)
18
Why do things move, he wondered.
1:36.96 – 1:38.46 (1.5s)
19
What holds the moon in the sky?
1:39.22 – 1:40.54 (1.3s)
20
That day, Newton was tired.
1:42.34 – 1:44.34 (2.0s)
21
He had spent weeks reading heavy books about planets and stars.
1:45.20 – 1:48.98 (3.8s)
22
His eyes hurt from squinting at tiny words.
1:50.26 – 1:53.02 (2.8s)
23
He leaned against the tree, feeling the rough bark on his back.
1:54.02 – 1:58.44 (4.4s)
24
The sun was low, painting the sky orange and pink.
1:59.40 – 2:03.10 (3.7s)
25
He closed his notebook and looked up.
2:04.14 – 2:06.30 (2.2s)
26
The leaves moved gently in the wind, making shadows dance on his face.
2:07.38 – 2:12.11 (4.7s)
27
He thought about the moon.
2:13.37 – 2:14.39 (1.0s)
28
It's so far, he said to himself.
2:16.11 – 2:18.47 (2.4s)
29
Why doesn't it fall like a stone?
2:19.75 – 2:21.27 (1.5s)
30
Suddenly, a small sound broke his thoughts.
2:23.13 – 2:26.57 (3.4s)
31
Thump!
2:27.09 – 2:27.37 (0.3s)
32
An apple fell from the tree, landing on the grass near his feet.
2:28.49 – 2:32.15 (3.7s)
33
Newton stared at it.
2:33.47 – 2:34.71 (1.2s)
34
The apple was round and red, with a tiny dent where it hit the ground.
2:35.75 – 2:40.99 (5.2s)
35
He picked it up, turning it in his hands.
2:41.13 – 2:44.29 (3.2s)
36
Why did you fall?
2:44.53 – 2:46.23 (1.7s)
37
He whispered.
2:46.71 – 2:47.95 (1.2s)
38
Most people would laugh and eat the apple, but Newton was different.
2:48.45 – 2:52.75 (4.3s)
39
His mind started to race.
2:53.19 – 2:55.41 (2.2s)
40
He looked at the tree, then at the sky.
2:55.77 – 2:58.87 (3.1s)
41
The apple falls to the ground, he thought.
2:59.65 – 3:02.81 (3.2s)
42
Does the moon want to fall too?
3:03.41 – 3:05.05 (1.6s)
43
Newton stood up, his heart beating fast.
3:06.17 – 3:09.25 (3.1s)
44
He paced under the tree, kicking grass with his boots.
3:09.71 – 3:13.81 (4.1s)
45
The apple was still in his hand.
3:14.21 – 3:16.43 (2.2s)
46
He dropped it again, watching it hit the earth.
3:16.91 – 3:20.11 (3.2s)
47
Something pulls it down, he said.
3:21.47 – 3:23.71 (2.2s)
48
He thought about stones, rain, even birds landing on branches.
3:23.25 – 3:28.29 (5.0s)
49
Everything fell toward the ground.
3:28.65 – 3:30.49 (1.8s)
50
But why?
3:30.73 – 3:31.81 (1.1s)
51
He sat again, opening his notebook.
3:32.81 – 3:35.19 (2.4s)
52
He drew the apple, the tree, and an arrow pointing down.
3:35.75 – 3:40.25 (4.5s)
53
A force, he wrote.
3:40.41 – 3:42.83 (2.4s)
54
A force pulls things.
3:42.63 – 3:44.79 (2.2s)
55
His mind jumped to the stars.
3:45.29 – 3:47.27 (2.0s)
56
He had read about planets moving in circles around the sun.
3:46.97 – 3:50.45 (3.5s)
57
What if the same force pulls the moon to the earth, he thought.
3:51.27 – 3:54.75 (3.5s)
58
He imagined a giant hand in the sky, holding everything together.
3:55.01 – 3:59.97 (5.0s)
59
But it wasn't a hand.
4:00.39 – 4:02.09 (1.7s)
60
It was something invisible.
4:02.67 – 4:04.01 (1.3s)
61
He called it gravity.
4:04.25 – 4:06.27 (2.0s)
62
The word felt right, like a key opening a locked door.
4:06.65 – 4:11.03 (4.4s)
63
He wrote faster, his pencil scratching loud in the quiet garden.
4:11.49 – 4:16.45 (5.0s)
64
The sun began to set, but Newton didn't notice.
4:17.39 – 4:21.35 (4.0s)
65
He was lost in ideas.
4:21.71 – 4:23.85 (2.1s)
66
He thought about cannonballs.
4:24.29 – 4:25.94 (1.6s)
67
If I shoot one far, it falls slower, he said.
4:27.14 – 4:30.60 (3.5s)
68
He drew a hill, a cannon, and a ball flying out.
4:31.42 – 4:34.38 (3.0s)
69
What if I shoot it so far, it never falls?
4:35.44 – 4:38.14 (2.7s)
70
Like the moon?
4:39.10 – 4:39.68 (0.6s)
71
His drawings grew wild.
4:41.50 – 4:42.94 (1.4s)
72
Curves.
4:43.84 – 4:44.62 (0.8s)
73
Circles.
4:45.26 – 4:45.70 (0.4s)
74
Lines crossing everywhere.
4:46.56 – 4:48.00 (1.4s)
75
He laughed.
4:49.54 – 4:50.24 (0.7s)
76
A rare sound.
4:50.24 – 4:52.10 (1.9s)
77
The Earth pulls the apple.
4:52.10 – 4:54.86 (2.8s)
78
The moon.
4:54.86 – 4:55.84 (1.0s)
79
Even me.
4:55.84 – 4:56.82 (1.0s)
80
Newton stayed under the tree until it was dark.
4:58.20 – 5:01.00 (2.8s)
81
The air grew cool and stars appeared.
5:01.00 – 5:04.30 (3.3s)
82
He looked up, seeing the moon glowing white.
5:04.66 – 5:09.14 (4.5s)
83
You're falling too, he told it, smiling.
5:09.38 – 5:13.60 (4.2s)
84
He felt like he found a secret.
5:13.60 – 5:16.08 (2.5s)
85
But he wasn't I need to test this, he thought.
5:16.08 – 5:22.64 (6.6s)
86
He knew math could help.
5:23.28 – 5:24.58 (1.3s)
87
He had learned about numbers that could explain movement, formulas from men like Galileo.
5:25.56 – 5:32.44 (6.9s)
88
He would use them to check his idea.
5:33.72 – 5:36.20 (2.5s)
89
The next day, Newton went to his room.
5:37.62 – 5:40.14 (2.5s)
90
It was small, with a wooden desk and shelves of books.
5:41.20 – 5:44.90 (3.7s)
91
He worked for hours, writing equations.
5:46.32 – 5:48.84 (2.5s)
92
He measured things.
5:50.30 – 5:51.46 (1.2s)
93
Apples, stones, even the distance to the moon.
5:52.12 – 5:56.20 (4.1s)
94
His mother called him for dinner, but he forgot to eat.
5:57.54 – 6:00.32 (2.8s)
95
Just a minute, he shouted, his pen moving fast.
6:01.60 – 6:04.78 (3.2s)
96
His sister Hannah peeked in.
6:05.08 – 6:06.62 (1.5s)
97
Isaac, you're strange, she said.
6:07.80 – 6:10.68 (2.9s)
98
He grinned.
6:11.30 – 6:11.90 (0.6s)
99
Maybe, but I'm right.
6:12.58 – 6:14.72 (2.1s)
100
Weeks turned to months.
6:15.52 – 6:17.00 (1.5s)
101
Newton kept his idea quiet.
6:17.54 – 6:19.60 (2.1s)
102
He was shy and didn't like fights.
6:19.70 – 6:23.26 (3.6s)
103
Other scientists might laugh.
6:23.72 – 6:26.08 (2.4s)
104
Falling moons?
6:26.38 – 6:27.74 (1.4s)
105
Silly, they'd say.
6:27.94 – 6:29.88 (1.9s)
106
But Newton worked on.
6:30.02 – 6:31.72 (1.7s)
107
He wrote letters to friends asking about stars and math.
6:31.82 – 6:36.26 (4.4s)
108
By 1667, the plague was weaker, and he went back to Cambridge.
6:36.36 – 6:41.23 (4.9s)
109
There, he shared his thoughts with a few people.
6:42.41 – 6:44.95 (2.5s)
110
Gravity, he said, it pulls everything.
6:45.81 – 6:48.43 (2.6s)
111
Apples, planets, everything.
6:48.97 – 6:50.57 (1.6s)
112
Some nodded.
6:52.43 – 6:53.19 (0.8s)
113
Others frowned.
6:53.97 – 6:54.69 (0.7s)
114
Years later, in 1687, Newton wrote a book, Mathematical Principles of Natural Philosophy, or Principia.
6:55.37 – 7:03.87 (8.5s)
115
It was long and heavy, full of math.
7:04.55 – 7:07.11 (2.6s)
116
He explained gravity, how it made apples fall and kept the moon in place.
7:08.05 – 7:13.61 (5.6s)
117
The book changed science.
7:14.79 – 7:16.51 (1.7s)
118
People read it in England, France, even faraway lands.
7:17.25 – 7:21.77 (4.5s)
119
They called Newton a genius.
7:23.05 – 7:24.95 (1.9s)
120
He didn't care for fame.
7:26.05 – 7:27.45 (1.4s)
121
I just watched an apple, he said laughing.
7:28.75 – 7:31.63 (2.9s)
122
Newton grew old, with white hair and deep lines on his face.
7:32.81 – 7:37.29 (4.5s)
123
He became a leader at Cambridge and helped run England's money.
7:38.21 – 7:41.59 (3.4s)
124
But he never forgot the apple tree.
7:42.45 – 7:44.45 (2.0s)
125
It was still there, in Woolsthorpe, growing old like him.
7:44.01 – 7:49.97 (6.0s)
126
Visitors came to see it, asking, Is this the tree?
7:51.43 – 7:55.11 (3.7s)
127
Newton nodded.
7:55.87 – 7:56.71 (0.8s)
128
Maybe, he said with a wink.
7:57.57 – 7:59.81 (2.2s)
129
He liked the story, even if it grew bigger than the truth.
8:00.09 – 8:04.49 (4.4s)
130
In 1727, Newton died at 84.
8:05.25 – 8:09.57 (4.3s)
131
His ideas lived on.
8:10.31 – 8:12.93 (2.6s)
132
Today, we use gravity to send rockets to space, to land on the moon.
8:13.53 – 8:19.91 (6.4s)
133
Scientists still read Principia.
8:20.89 – 8:23.97 (3.1s)
134
The apple tree is gone, but its story stays.
8:24.67 – 8:27.83 (3.2s)
135
A tale of a young man who saw fruit fall and asked why.
8:28.35 – 8:33.11 (4.8s)
136
Newton once looked at the stars and thought, can one question open the sky?
8:34.13 – 8:39.35 (5.2s)
137
His life said yes.
8:39.91 – 8:41.81 (1.9s)
138
From a quiet garden, he gave the world a new way to understand everything.
8:42.51 – 8:48.91 (6.4s)
この動画でスピーキングを練習する理由は？
この動画「世界を揺るがしたリンゴ」は、英語学習者にとって非常に効果的なスピーキング練習の機会を提供します。物語を用いて学ぶことで、リアルな文脈の中で発音や文法を習得できるだけでなく、理解力を深めることができます。重要なのは、アイザック・ニュートンの物語という背景を通じて、思考を刺激し、英語の表現を生き生きと体感することです。このような練習は、特に英語シャドーイングや英語スピーキング練習を行う際に非常に役立ちます。動画内のストーリーは、単なる事実の羅列ではなく、情景描写や感情が豊かに盛り込まれており、発話の練習がしやすいのです。
文法と表現の文脈
この動画では、以下の重要な構造が使用されています。
- 疑問文：「Why do things move, he wondered.」疑問文を使うことで、ニュートンの思考過程を表現しています。学習者は、自分の考えを英語で表現する際にこの形式を使うことができます。
- 過去形の使用：「Newton was a young man of 23, living in a small village...」過去の出来事について語ることで、語彙や文法の強化に繋がります。
- 比喩表現：「Everything fell toward the ground.」この比喩的な表現は、英語の文脈で考えや感情を言葉で描写する際に有用です。
これらの構造は、YouTubeで英語学習を進める際に非常に役立ち、実際の会話でも姿勢を整え、表現力を向上させる助けとなります。
一般的な発音の罠
動画には、いくつかの発音の難しい単語やアクセントがあります。特に注目すべきは次の点です。
- 「apple（リンゴ）」の発音：英語の母音「a」に注意し、はっきりと発音することが求められます。
- 「fall（落ちる）」と「fell（落ちた）」の過去形：これらの単語は、強い子音で終わるため、しっかりと発音を練習しましょう。
- 「gravity（重力）」：この単語は音節が多く、正しいアクセントを置くことが必要です。
これらのトラップを克服することで、より自然な会話ができるようになります。英語シャドーイングを活用して、自分の声を録音することで、発音やイントネーションの改善を図りましょう。
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。
ShadowingEnglishでの効果的な学習方法
- 動画を選ぶ: 自然で明瞭な英語が使われているYouTube動画を選びましょう。TED Talks、BBC News、映画のシーン、ポッドキャスト、IELTS模範解答などが最適です。URLをコピーして検索バーに貼り付けてください。短い動画（5分以内）や、自分が本当に興味を持てるテーマから始めるのがコツです。
- まず聞いて内容を理解する: 最初は1倍速でただ聞くだけにしましょう。まだ繰り返す必要はありません。文の意味を理解し、話者がどのように単語を強調し、音を繋げ、間を取っているかに注目してください。内容を把握してからシャドーイングに入ると、はるかに効果的です。
- シャドーイングモードを設定する:
- Wait Mode（待機モード）:
+3sまたは+5sを選ぶと、動画が一文を読み終えた後に自動で一時停止し、繰り返す時間が生まれます。完全に手動でコントロールしたい場合はManualを選んでNextを自分で押しましょう。 - Sub Sync（字幕同期）: YouTubeの字幕と音声がずれることがあります。
±100msで調整して、正確なタイミングで追えるようにしてください。
- Wait Mode（待機モード）:
- 声に出してシャドーイングする（最重要）: ここが練習の本質です。文が流れると同時に——または一時停止中に——はっきりと自信を持って声に出して繰り返しましょう。ただ単語を読むだけでなく、話者のリズム、強調、高低、連音をそっくりそのまま真似することが大切です。「影」のように話者に重なるのが理想。Repeat機能を使って同じ文を何度も繰り返し、自然に出てくるまで定着させましょう。
- 徐々に難易度を上げて続ける: 一つのパッセージに慣れたら、さらに挑戦してみましょう。速度を <code>1.25x</code> や <code>1.5x</code> に上げれば、高速の言語反射を鍛えられます。Wait Modeを <code>Off</code> にして連続シャドーイングするのが最も上級で効果的なモードです。毎日15〜30分継続すれば、数週間で目に見える変化を実感できます。
