Hello.
0:09.34 – 0:09.78 (0.4s)
2
This is 6 Minute English from BBC Learning English.
0:09.78 – 0:13.18 (3.4s)
3
I'm Beth.
0:13.18 – 0:13.90 (0.7s)
4
And I'm Neil.
0:13.86 – 0:15.04 (1.2s)
5
Phew, I've spent a day in meetings, then shopping, then collecting the kids from school.
0:15.04 – 0:20.66 (5.6s)
6
I'm exhausted, Beth.
0:20.50 – 0:22.02 (1.5s)
7
What have you been doing today?
0:22.02 – 0:23.74 (1.7s)
8
Not much.
0:23.90 – 0:25.10 (1.2s)
9
Just sitting around, doing nothing, relaxing and kicking back.
0:25.10 – 0:29.22 (4.1s)
10
Lucky you.
0:29.34 – 0:30.22 (0.9s)
11
Don't you have any work to do?
0:30.22 – 0:31.58 (1.4s)
12
It may not look it, Neil, but I'm actually as busy as a bee.
0:31.64 – 0:35.40 (3.8s)
13
If you've seen nature documentaries about worker bees flying from flower to flower, you probably think animals are always on the move.
0:35.40 – 0:44.36 (9.0s)
14
But the surprising truth is, away from the cameras, most animals spend most of their time doing absolutely nothing at all.
0:44.36 – 0:52.54 (8.2s)
15
In the natural world where finding food and shelter is hard work, why have some animals evolved to do nothing.
0:52.58 – 1:00.02 (7.4s)
16
And if it's good enough for animals, would being lazy work for humans too?
1:00.02 – 1:04.94 (4.9s)
17
That's what we'll be discussing in this programme and, as usual, we'll be learning some useful new vocabulary as well.
1:04.94 – 1:12.22 (7.3s)
18
But first, let me work up the energy to ask you a question, Neil.
1:12.62 – 1:17.02 (4.4s)
19
Of course, some animals have a reputation for lounging about.
1:17.02 – 1:21.56 (4.5s)
20
Lions, for example, can sleep up to 20 hours a day.
1:21.56 – 1:25.86 (4.3s)
21
what is the slowest moving animal on earth?
1:26.40 – 1:29.88 (3.5s)
22
Is it...
1:29.88 – 1:31.00 (1.1s)
23
a the giant tortoise, b the three-toed sloth, or c the koala?
1:30.70 – 1:38.32 (7.6s)
24
Well, I think it's the three-toed sloth.
1:38.56 – 1:41.88 (3.3s)
25
OK, Neil.
1:42.18 – 1:42.70 (0.5s)
26
I'll reveal the correct answer at the end of the programme.
1:42.70 – 1:46.06 (3.4s)
27
Now, it's no surprise that lazy lions love relaxing, but even animals with reputations for being busy spend time doing nothing.
1:46.92 – 1:56.42 (9.5s)
28
Look carefully into an ant's nest and you'll see around half of them just sitting there motionless.
1:57.46 – 2:03.48 (6.0s)
29
Here's Professor Dan Charbonneau, an expert in insect behaviour, discussing the lazy rock ant with Emily Knight, presenter of BBC Radio 4 programme Naturebang.
2:04.18 – 2:15.70 (11.5s)
30
Dan's research has focused on ant colonies, a species called Temnothorax regatulus or the rock ant.
2:19.10 – 2:24.32 (5.2s)
31
I think ants are sort of a symbol of industriousness.
2:24.48 – 2:27.20 (2.7s)
32
They have this whole tiny little society going on that's kind of similar to ours.
2:27.24 – 2:31.34 (4.1s)
33
Some idealised version of what humans might be, if we could only pull it together and all work together, we could be as industrious as the ants.
2:31.60 – 2:38.06 (6.5s)
34
But then when you look at it, roughly about half the colony is inactive at any given time.
2:38.52 – 2:42.50 (4.0s)
35
We think ants are industrious or hard-working.
2:46.20 – 2:48.98 (2.8s)
36
Groups of ants called colonies seem tiny, perfect societies where everyone works hard for the good of the group.
2:49.64 – 2:56.94 (7.3s)
37
Then why are so many of them inactive?
2:56.72 – 2:59.66 (2.9s)
38
One possible answer is that they're reserve ants, ready to step in if disease or disaster strike.
2:59.64 – 3:07.20 (7.6s)
39
But could it simply be that they don't work because they don't need to?
3:07.76 – 3:12.08 (4.3s)
40
Would you get out of bed on Monday morning if you didn't have to?
3:12.42 – 3:16.04 (3.6s)
41
Maybe the ants can teach us a thing or two about relaxing, but wouldn't it get boring just sitting around all day?
3:16.08 – 3:23.06 (7.0s)
42
Not according to psychologist Dr Sandy Mann.
3:23.12 – 3:26.62 (3.5s)
43
She thinks being productive – working to produce a lot for the amount of resources we use is overrated.
3:26.94 – 3:34.04 (7.1s)
44
Boredom has its benefits too, as she explained to BBC Radio 4 programme Naturebang.
3:34.04 – 3:40.40 (6.4s)
45
Would humans have invented bread or beer or fire, you know, if we hadn't been bored and were wondering what on earth would happen if we mixed this with this, you know?
3:42.22 – 3:51.94 (9.7s)
46
Are all these sorts of inventions the mother of boredom?
3:51.94 – 3:55.42 (3.5s)
47
But in this world of constant stimulation, Switching off is harder than it's ever been.
3:55.42 – 4:01.38 (6.0s)
48
That's why we're constantly swiping and scrolling and looking for the next big thing and the new thing and we get bored of things very quickly.
4:01.40 – 4:07.48 (6.1s)
49
So it's a kind of paradox to get rid of this unpleasant state of boredom is actually to allow more boredom into your life.
4:07.48 – 4:13.70 (6.2s)
50
Doctor Man doubts humans would have invented things without the curiosity that comes from being bored.
4:15.78 – 4:21.96 (6.2s)
51
Boredom is the mother of invention, an idea based on the famous proverb Necessity is the mother of invention – an idiom meaning that if you really need to do something, you will think of a way of doing it.
4:22.42 – 4:35.70 (13.3s)
52
Instead of fearing boredom, we can open up to its benefits by switching off.
4:35.80 – 4:41.02 (5.2s)
53
Stopping worrying or thinking about something and relaxing.
4:41.02 – 4:45.46 (4.4s)
54
Slowing down helps too – something we can definitely learn from our animal cousins.
4:45.42 – 4:50.84 (5.4s)
55
I think now is a good time to reveal the answer to my question, since we have nothing else to do.
4:51.28 – 4:56.42 (5.1s)
56
You asked me to name the world's slowest animal and I guessed it was the three-toed sloth.
4:56.52 – 5:02.18 (5.7s)
57
Was I right?
5:02.18 – 5:02.96 (0.8s)
58
That was the correct answer.
5:03.02 – 5:05.32 (2.3s)
59
With a top speed of 30 centimetres per minute, three-toed sloths move so slowly that algae grows on their coats.
5:05.32 – 5:15.48 (10.2s)
60
OK, let's recap the vocabulary we've learnt from this programme, starting with the phrase, kicking back, to stop doing things and relax completely.
5:16.22 – 5:25.30 (9.1s)
61
The adjective industrious means hard-working.
5:26.16 – 5:29.16 (3.0s)
62
A colony is the name given to a group of certain animals, including ants and some seabirds.
5:30.00 – 5:35.80 (5.8s)
63
beds.
5:35.32 – 5:36.22 (0.9s)
64
Someone who is productive is able to produce a lot for the amount of resources they use.
5:36.70 – 5:42.20 (5.5s)
65
The proverb, necessity is the mother of invention, means that if you really need to do something, you will think of a way of doing it.
5:43.04 – 5:50.46 (7.4s)
66
And finally, to switch off means to stop worrying or thinking about something and relax.
5:50.42 – 5:56.58 (6.2s)
67
Once again, our six minutes are up.
5:57.62 – 5:59.46 (1.8s)
68
It must be time to sit down, close your eyes and just do nothing.
5:59.46 – 6:03.54 (4.1s)
69
Goodbye for now.
6:03.06 – 6:04.78 (1.7s)
70
Bye.
6:05.32 – 6:05.50 (0.2s)

主な学習ポイントとしては、以下が挙げられます。
- 新しい語彙とフレーズの習得
- 効果的なスピーキングの文脈での練習
- 英語の文法パターンの理解
重要な語彙とフレーズ
- doing nothing - 何もしないこと（リラックスすること）
- industrious - 勤勉な（働き者の）
- boredom - 退屈（やることがない状態）
- curiosity - 好奇心（新しいことを知りたい思い）
- reserve ants - 予備のアリ（他のアリが働けない時に働くアリ）

この動画の練習のコツ
この動画の内容を通じたシャドーイングは、スピーキング能力の向上に有効です。以下のポイントを意識して練習しましょう。
- 話速：動画のスピーカーよりも少し遅めに話すことで、正確な発音とイントネーションを習得できます。
- アクセント：スピーカーのアクセントに合わせて練習することで、自然な英語のリズムを身につけましょう。
- トピックの難易度：内容がやや難しく感じる場合もありますが、理解を深めることで英語力が向上します。
特にこのレッスンでは、休息の重要性がテーマであり、それに基づいた発音練習やフレーズを使うことで、英語での表現力も増します。英語スピーキング練習やIELTS対策にも活用できます。
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。
