Hello.
3
This is 6 Minute English from BBC Learning English.
4
I'm Phil.
5
And I'm Georgie.
6
We all know how important exercise is to stay fit and reduce the risk of heart disease.
7
Do you exercise much, Phil?
8
I try to.
9
I ride my bike at the weekend.
10
But to be honest, I do spend a lot of time sitting down.
11
Hmm, sitting too much is becoming an increasing problem in the modern world.
12
Maybe you take the bus or train to work,
13
then sit at a desk all day,
14
then go home feeling tired and just sit in front of the television all evening as well.
15
Added together, that's hours of sitting every single day.
16
In this programme, we'll be finding out exactly how much sitting is too much.
17
And of course, we'll be learning some useful new vocabulary.
18
But first, are you sitting comfortably, Phil? because I have a question for you.
19
On average, how many hours a day do British adults spend sitting down?
20
Is it a 7 hours,
21
b 9 hours or c 12 hours?
22
I'll guess it's 7 hours.
23
OK Phil, I'll reveal the correct answer later.
24
Charlotte Edwardson is a professor of health
25
and behaviour studies who has investigated the link between sitting and health problems in her lab at Leicester University.
26
Here, she talks to BBC Radio 4 programme Inside Health.
27
If we think about our daily activities,
28
a lot of activities are done sitting down.
29
Movement in our everyday lives has really been engineered out with advances in technology
30
and our bodies just weren't designed to sit this much,
31
so it's going to cause problems with our health.
32
So when you sit down,
33
you're not using the largest muscles in your body,
34
so these are the ones in your legs and your bum.
35
So that means that your muscle activity goes down.
36
When your muscle activity goes down, your blood circulation reduces.
37
Throughout history, humans have always walked and moved their bodies.
38
Now, modern technologies like motorised vehicles and office jobs means we spend more and more time sitting.
39
Modern life has engineered out the need for us to move.
40
When you engineer something out,
41
you design things in such a way that it is no longer required.
42
For example, CD drives have been engineered out of laptops because downloads are more popular.
43
Charlotte says humans are not used to sitting this much.
44
Here, the words this much mean in such large amounts.
45
It's a negative thing – one negative being the harm to
46
blood circulation – the flow of blood through the heart and blood vessels,
47
which carries oxygen around the body.
48
When we sit, we stop using important muscles.
49
This reduces blood circulation and causes a range of other effects,
50
like increased levels of glucose and fat and decreased energy levels.
51
The body uses 20% more energy when simply standing than when sitting down,
52
and walking uses 92% more energy.
53
And that's not to mention the damage sitting too much causes to muscle movement and blood pressure.
54
But the hard truth is that sitting is a big part of modern life.
55
Everything is geared around sitting.
56
It's organised towards that particular activity.
57
And that makes it hard to stop.
58
Here's Professor Edwardson again, talking with James Gallagher,
59
presenter of BBC Radio 4 programme Inside Health.
60
How much do you feel like you're just swimming against the tide with all of this?
61
Like the whole of society is like driving us more and more towards,
62
you know, sitting down all the time.
63
And you're like, please don't.
64
Sitting is so much part of our everyday activities.
65
You know, you go into a meeting and someone's like,
66
come and take a seat.
67
You go into your GP surgery,
68
come and take a seat.
69
Everything's geared around sitting and as technology advances and it tries to make our life easier,
70
it then leads to us sitting even more.
71
James asks if Charlotte is swimming against the tide of modern life.
72
If you're swimming against the tide,
73
you're doing the opposite of what most people are doing.
74
He also says that society is driving us towards sitting more.
75
To drive someone towards something means pushing them to accept a new situation,
76
even when the situation isn't so good.
77
Luckily, there's some simple advice to help.
78
Break up periods of sitting 30 minutes or more with a few minutes of walking or moving your arms.
79
Also, try to spend less than half of your waking hours sitting down.
80
Good to know.
81
Now, about your question, Georgie.
82
Right.
83
My question was how long does the average British adult spend sitting each day?
84
Phil guessed it was seven hours,
85
which was close, but not right, I'm afraid.
86
In fact, on average, we spend nine hours per day sitting down.
87
That's about 60% of our waking life.
88
So remember to take regular breaks,
89
even just a minute or two.
90
OK, let's recap the vocabulary we've learnt,
91
starting with to engineer something out,
92
meaning to design or plan in such a way that something is no longer needed.
93
The phrase this much or so much means in such large amounts.
94
Blood circulation is the movement of blood through the heart and blood vessels which carries oxygen around the body.
95
If things are geared around a certain activity or purpose,
96
they're organised to support it.
97
The idiom to swim against the tide means to not follow what most people are doing.
98
And finally, to drive someone towards a new situation means to push them towards accepting it.
99
Once again, our six minutes are up.
100
Remember to join us again next time for more topical discussion and useful vocabulary here at 6 Minute English.
101
Goodbye for now!
102
Bye!

この動画で話す練習をする理由
英語を学ぶ際、リスニングだけでなくスピーキングも重要です。この動画は、現代社会における座ることの健康への影響について語っています。このトピックは、私たちが日常生活でどれだけ座っているか、そしてそれが身体に及ぼす影響について深く考えさせられます。話の内容を通じて、英語の発音を良くするために、特にトーンやリズムを模倣することができるため、英語シャドーイングの練習に最適です。動画の中での対話を再現することで、より自然な会話能力を養うことができます。
文法と表現の文脈
- 動名詞と不定詞の使い分け：「sitting down」や「to move」などのフレーズは、行動を表現するのに効果的です。これらの表現を使うことで、日常生活の中での活動を具体的に描写できます。
- 過去形と現在形の対比：「humans have always walked」と「we spend more time sitting」の対比は、過去と現在の習慣の違いを明確に示すための良い例です。
- 比喩表現：「engineered out」：このフレーズは、技術の進化が私たちの生活様式に与える影響を示しています。新しい言語表現として覚えておくと良いでしょう。
- 疑問文の使い方：「How much sitting is too much?」のような質問形式は、会話を進めるための効果的な方法です。このような表現を使えると、より活発なコミュニケーションが可能になります。
一般的な発音のワナ
動画内ではいくつかの難しい単語や発音があります。例えば、「circulation」という単語は、スピードやアクセントに注意が必要です。また、shadow speakを用いた練習により、このような言葉の正確な発音が身につきます。特に、「engineered out」などのフレーズは、つながりや母音を強調する練習に役立ちます。英語の発音を良くするためには、これらの言葉を繰り返し練習することが効果的です。
このようなポイントを意識しながら、shadowspeaksのような方法で、リスニングとスピーキングのスキルを同時に向上させることができます。動画を利用して、是非色々な発音や表現を練習してみましょう。
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。
