This recording is from the British Council.
2
So you've got a few minutes to discuss with your partner.
3
So, as far as I know, the main similarity between Mars and Earth is that they can both support human life.
4
Yeah, but do we know that's actually true?
5
I mean, Mars is much colder than Earth, isn't it?
6
It says here it's about minus 55 degrees most of the time, whereas on Earth, only places like Antarctica get that cold.
7
True.
8
Well then, I suppose you could say both planets are a similar distance from the Sun.
9
No way!
10
Mars is much further away.
11
It says here it's about 228 million kilometers, while Earth is about 150 million.
12
Yes, but in space that's not that far.
13
Jupiter is like almost 780 million kilometers.
14
That's why we use astronomical units when we talk about distance in space.
15
Earth is one astronomical unit from the Sun and Mars is 1.3.
16
The difference doesn't sound so big when you look at it that way.
17
I see what you mean.
18
Jupiter is 5.2 astronomical units, so I guess you're right.
19
What other similarities are there between the two planets?
20
Let's see.
21
Not the colour, obviously.
22
Yeah.
23
Earth is called the blue planet and Mars is called the red planet for pretty obvious reasons.
24
Their sizes are pretty different.
25
Mars is about half the size of Earth.
26
What about this?
27
It looks like the days on both planets are almost the same length.
28
Earth's day is 24 hours, but Mars' is about half an hour longer.
29
You're right.
30
Okay.
31
Any other things they both share?
32
Um, I suppose you could say they have water in common. Could you?
33
How?
34
Well, Earth is 70% water, and Mars probably had huge oceans in the past.
35
It's just that most of the water there now is probably frozen.
36
Ah, I see.
37
I don't think we can say the air is the same, though.
38
Most of Earth's air is nitrogen and oxygen. But Mars...
39
Mars doesn't really have air, not compared with Earth.
40
It's got about 1% as much air as Earth.
41
Right, and it's mostly carbon dioxide.
42
Gravity is another difference.
43
I didn't know this, but Mars has higher gravity than the Moon.
44
But it's much less than on Earth, of course.
45
Oh, yes.
46
It says Mars has about 38% of Earth's gravity.
47
Okay, let's see what you've found.

关于本课
您正在使用跟读技巧通过视频"A student discussion"练习英语口语和发音。
每天练习15到30分钟，将显著提高您的英语流利度和发音准确度。
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。
