1
The Earth is a great day.
2
So, you're thinking of moving to Mars.
3
Have you picked out a spot for your new home?
4
No?
5
Well, I'm here to help.
6
First things first, here are some of the things you'll need to bring to the Red Planet.
7
A high tolerance for cold, loneliness, and radiation.
8
a lifetime supply of breathable air and food, a multi-billion dollar spaceship, a desire to just get away from it all, and water.
9
You're definitely going to need water.
10
So what sort of real estate are you looking for?
11
How about a mansion in the maze-like Noctis Labyrinthus, a hideaway in the Happy Face Crater, a fortress on the Face Mesa,
12
an ocean view, Uh, bad news on the last one.
13
You're about four billion years late.
14
We're pretty sure that Mars used to have oceans, lakes, rivers, the whole package.
15
But over time, almost all of it froze beneath the surface or evaporated off into space.
16
There's probably still some trapped beneath the seasonally expanding and contracting carbon dioxide ice caps, though.
17
So what might Mars look like today if it had surface water?
18
That, of course, depends on how much we're talking about, it may be something like this.
19
The relatively flat northern hemisphere is below the average elevation, so it would become one giant ocean,
20
while the crater-ridden southern hemisphere would stay mostly high and dry.
21
That difference between hemispheres is a bit bizarre, and we don't know why it's like that.
22
The southern half is probably much older, judging by features like the number of craters and the evidence of increased volcanic activity in the north.
23
Okay, so who knows, maybe one day Mars will have oceans again.
24
But for now, what we've got is essentially one giant, dusty desert.
25
In fact, it's similar enough to deserts on Earth
26
that we've been able to learn a great deal about Mars on our home planet.
27
For instance, Martian sand dunes form and behave similarly to our sand dunes,
28
though the Martian versions often grow twice as large thanks to a gravitational pull that's about a third as strong as ours.
29
And Mars has some features you won't see on Earth, like TARS, which are crestless sand dunes up to 15 meters tall,
30
whose formations we have yet to understand.
31
You're probably wondering, what do you get when you combine a planet-wide desert with an atmosphere that,
32
like ours, is subject to wind-generating pressure differentials, dust storms?
33
These will be your main weather hazards on the red planet.
34
They play a large part in making the planet red by distributing rusted iron particles across the surface and into the air.
35
Thanks to the low gravity and lack of moisture, these dust storms can last for months and cover the planet.
36
So, you might want to build your home as high as possible.
37
Well, look no further.
38
This is Olympus Mons, the largest volcano in the solar system.
39
Even if Mars had a breathable atmosphere, you'd find the views from the 25-kilometer summit breathtaking.
40
Or are volcanoes not your thing?
41
Then how about Valles Marineris, the largest canyon in the solar system?
42
It's so wide that from one side, the opposite rim would be below the curve of the horizon.
43
Still, you'll catch some spectacular blue sunsets in the normally red sky,
44
which gets its color from the dust absorbing most of the blue light and the way sunlight is scattered by the atmosphere. Have you got spirit?
45
Curiosity?
46
Or are you just looking for opportunity?
47
Then stop stalling and make the move to Mars today.

本课程简介
在这一课程中，您将通过视频学习有关火星的知识，同时提升您的英语口语能力。通过加深对火星环境的理解，您可以练习表达复杂的科技与探索主题，这对于雅思口语练习尤为重要。我们将专注于精确的词汇和短语，帮助您在与他人讨论宇宙探索时更加自信。
重点词汇与短语
- 火星 (Mars)
- 气候 (climate)
- 沙丘 (sand dunes)
- 尘暴 (dust storms)
- 宇宙探索 (space exploration)
- 无重力 (microgravity)
- 红色星球 (Red Planet)
- 最高峰 (summit)
练习技巧
为了有效提高您的英语口语能力，建议您采用shadow speech的练习方式。先听一段视频，然后跟读。注意视频的语速和语调，尽量模仿。比如，视频中的火星描述部分使用的词汇挑战性较大，因此您可以逐句停下来，缓慢推动自己的发音，达到英语口语练习的效果。
您可以从一开始模仿发音，逐渐提高语速，以便最终自然地进行对话。通过这种方法，您不仅会掌握火星相关的词汇，还会改善您在实际交流中的流利度。这对于准备雅思口语练习尤其重要，因为考试中要求能够清晰、自信地表达想法。
在模仿时，尝试着把自身的感情加入到演练中，这样您可以更加投入，也会使您的发音更具生动性。记住，shadowspeaks过程中，不要害怕犯错误！每次练习都是进步的机会。
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。
