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.

本课内容简介
在这一课中，学习者将探讨有关寻找外星生命的话题，通过科学专家的观点了解生命存在的条件。您的目标是提高英语口语能力，特别是通过影子跟读的方法，准确模仿说话者的语调和节奏。通过这样的练习，您将能够更自信地在日常交流中运用英语。
重要词汇与短语
- Exoplanet（系外行星） - 一个存在于其他太阳系中的行星。
- Habitable zone（适居区） - 适合生命存在的区域。
- Atmosphere（大气层） - 行星周围的气体，影响生命的可能性。
- Potential（潜力） - 具有未来发展能力的可能性。
- Rule out（排除） - 驳回某种可能性或想法。
- Fingers crossed（祈祷好运） - 表达希望结果积极的情感。
- Temperature（温度） - 一种影响生物生存环境的重要因素。

练习建议
在进行影子跟读时，请注意视频的说话速度和语调。由于这段内容的语速适中，您可以尝试逐句模仿说话者。在收听时，专注于他们的语音、重音和停顿。您可以提前暂停视频，重复模仿每句话，同时尽量保持语音的自然流畅。在这个过程中，尝试使用英语影子跟读的技巧，即在听的同时说出相同的句子，确保您的发音尽可能接近原声，这将提升您的英语口语练习效果。此外，您还可以使用shadow speech的方法，记录自己的声音，与原音进行比较，找出需要改进的地方。
通过不断练习，您将提高语言的灵活性和表达能力，使自己更加自信地用英语交流。在这段探讨外星生命的对话中，勇于模仿，将有助于您掌握更复杂的句子结构及其应用，最终帮助您踏上流利表达的道路。
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
