Hello, this is 6 Minute English from BBC Learning English.
2
I'm Neil.
3
And I'm Bekah.
4
Neil, do you believe that life exists away from planet Earth?
5
Well, I'm not sure about the kind of little green men that you see in science fiction movies, but also I think we cannot be alone in the universe.
6
What about you, Bekah?
7
What do you think?
8
I agree.
9
I think that maybe life does exist beyond our planet, but maybe not as we see in alien movies.
10
Well, in this episode we'll be learning from science and space experts about whether the conditions for life exist on a planet 40 light years away.
11
Yes, and as usual you can find a transcript for this episode, along with all the vocabulary and a worksheet, on our website, bbclearningenglish.com OK, a quiz question for you, Becca.
12
How long would it take to drive a car to the sun at 100 kilometres an hour?
13
Is it a 70 years, b 170 years or c 1,700 years?
14
Well, Neil, the sun seems very far away, so I'll go for c 1,700 years.
15
I hope you have enough petrol for that.
16
Well, we'll find out the answer to the question later.
17
Now though, some science and space experts are excited about a planet in a different solar system from our own.
18
Science journalist Caroline Steele talks about this discovery on the BBC World Service programme What in the World?
19
Caroline Steele, So scientists have been looking at an exoplanet, so that's a planet that exists in a solar system that isn't our own, called Trappist-1e.
20
And it's a rocky planet like Earth.
21
It's a similar size to Earth and it exists in the habitable zone around its sun.
22
And its sun is called Trappist-1.
23
Caroline explains that scientists have discovered that the planet Trappist-1e exists in the habitable zone around its sun.
24
The adjective habitable describes a place or habitat that is suitable for something to live.
25
Yes, and a zone is an area with a particular feature.
26
For example, people who live in earthquake zones have to be prepared for danger.
27
So a habitable zone is an area where something could live.
28
Caroline goes on to explain why they think TRAPPIST-1e may be habitable.
29
Scientists have been looking at the potential atmosphere around TRAPPIST-1e and they've ruled out that it's really full of hydrogen or carbon dioxide, which is a great thing because they're greenhouse gases which would make the planet really hot.
30
And there are some small clues that it might be a nitrogen dominated atmosphere, which again is another sort of clue that there could be life there.
31
Caroline Steele says that scientists are looking at the potential atmosphere around Trappist-1e.
32
That is, they want to find out if the atmosphere is capable or likely to become able to host life.
33
If something has potential, it already has the qualities or abilities to do something.
34
The adjective potential has a similar meaning but refers to future capability.
35
Exactly.
36
We could say the data has potential in that it shows signs of helping the research, But when we talk about potential data, we're referring to data that could help us with future research.
37
She also mentions how scientists have ruled out that TRAPPIST-1e is full of hydrogen or carbon dioxide.
38
The phrasal verb rule out means to dismiss the possibility or idea of something.
39
Scientists have found that TRAPPIST-1e is not full of those greenhouse gases.
40
They've ruled it out.
41
Indeed.
42
And Caroline goes on to say how the atmosphere of Trappist-1e is dominated by nitrogen.
43
If something is dominated by something else, it is controlled by it or is the most significant element of it.
44
Trappist-1e is full of nitrogen, which is exciting because nitrogen is a sign of life and habitability.
45
So what if nitrogen is actually found on this planet?
46
Caroline Steele has more.
47
My guess is what we'll do is try and see what other gases are in the atmosphere and use models to work out how warm the planet could be and
48
whether or not it's a temperature that basically could support life or it maybe it's too hot or too cold but fingers crossed it has a nitrogen there's enough of it to keep the planet a decent temperature and then that's one step closer to finding life.
49
Caroline guesses that scientists will focus on the planet's temperature and whether it could support life.
50
She uses the expression fingers crossed to express hope for a positive outcome.
51
Yes, we often make the physical gesture of crossing our fingers for good luck.
52
We do.
53
That reminds me, Neil, the answer to your question.
54
Fingers crossed that I answered correctly.
55
I see what you've done there, Becca.
56
Yes, I asked you how long it would take to drive to the sun.
57
at 100 kilometres an hour and you answered C, 1,700 years.
58
Well, the sun is very far away, but the answer was B, only 170 years.
59
Ah, well, that's still longer than my lifetime.
60
Now let's have a recap of the language we've learnt in this episode, starting with habitable, which describes a place or habitat that is suitable for something to live.
61
A zone is an area with a particular feature.
62
Potential describes having possible qualities or abilities to do something.
63
The phrasal verb rule out means to dismiss the possibility or idea of something.
64
We also had dominated.
65
If something is dominated by something else, it is controlled by it or is the most significant element of it.
66
And finally, the expression fingers crossed is used to wish for hope or luck.
67
Once again, our six minutes are up, but head over to our website bbclearningenglish.com for a quiz and worksheet for this episode.
68
See you soon.
69
Bye for now.
70
Bye.

このレッスンについて
このレッスンでは、宇宙や生命の存在に関する科学的な知識を学びながら、リスニングとスピーキングのスキルを向上させます。特に、英語でのシャドーイング（英語シャドーイング）を通じて、発音やイントネーションを改善し、流暢さを高めることを目指します。このビデオの内容は、異惑星での生命の可能性に関するもので、さまざまな専門用語が登場するため、実践的で興味深い学習体験を提供します。
重要なボキャブラリーとフレーズ
- エクソプラネット (exoplanet) - 地球以外の太陽系に存在する惑星。
- 居住可能区域 (habitable zone) - 生命が存在できる条件を満たしている可能性のある領域。
- ガス (gas) - トラピスト-1eの大気中に含まれるかもしれない成分。
- 窒素 (nitrogen) - 生命の存在を示す可能性があるガス。
- ルールアウト (rule out) - 可能性や考えを排除する。

練習のコツ
このビデオのスピードは、中程度で、発音も明瞭です。シャドーイングを行う際には、まずは音声を何度か聞いて、内容を理解しましょう。その後、以下のステップを実行してみてください。
- ビデオを再生し、ナレーターの発話に合わせて同じ速度で声に出してみましょう。このプロセスは、英語スピーキング練習に非常に効果的です。
- 特に難しい単語やフレーズが出てきた場合は、何度も繰り返して練習し、正しい発音を身につけることが大切です。
- ナレーションのトーンや感情を真似ることで、表現力を高めることを意識して練習してください。これは、IELTSスピーキング対策にも役立ちます。
- YouTubeで英語学習をしている場合は、他のビデオも参考にしながら、異なるアクセントやリズムに触れることをお勧めします。
この練習を通じて、より自然な会話力を身につけ、英語の世界を広げていきましょう！
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。
