So you're thinking of moving to mars. Have you picked out a spot for your new home? no. Well, i'm here to help. First things. First, here are some of the things you'll need to bring to the red planet a high tolerance for cold loneliness and radiation, a lifetime supply of breathable air and food, a multibillion dollar space ship, a desire to just get away from at all and water. You're definitely going to need water. So what sort of real estate are you looking for? How about a mention in the maze like noctis levein, thus a higher way in the happy face crater, a fortress on the face. Masa, an ocean view. Bad news on the last one. You're about four billion years later. We're pretty sure that mars used to have oceans, lakes, rivers, the whole package. But over time, almost all of IT throws beneath the surface or evaporated off into space. There's probably still some trapped beef, the seasonally expanding and contracting carbon dioxide ice caps though. So what might mars look like today if I had surface water? That, of course, depends on how much we're talking about, but maybe something like this. The relatively flat northern hemisphere is below the average elevation, so IT would become a one giant ocean, while the crater ridden southern hemisphere would stay mostly high and dry. That difference between hemisphere is a bit bizarre, and we don't know why it's like that. 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. Okay, so who knows? Maybe one day mars will have oceans again. But for now, what we've got is essentially one giant dusty desert. In fact, it's similar enough to deserts on earth that we've been able to learn a great deal about mars. On our home planet, for instance, martian sand dunes form and behave similarly to our sand dunes, though the martian versions often grow twice as large, thanks to a gravitation pull that's about a third as strong as ours. And mars has some features you won't see on earth, like tars, which are restless sandton s up to fifteen meters tall, whose formations we have yet to understand. You're probably wondering, what do you get when you combine a planet wine desert with an atmosphere that, like ours, is subject to wind generating, pressure differences, dust storms? These will be your main weather hazards on the red planet. They play a large part in making the planet red by distributing rusted iron particles across the surface and into the air. Thanks to the low gravity and lack of moisture, these dust storms can last for months and cover the planet so you might wanna build your home as high as possible. Well, look no further. This is olympus minds, the largest volcano in the solar system. Even if mars had a breathable atmosphere, you'd find the views from the twenty five kilometers mmi breath taking or our volcanoes. Not your thing. Then how about voice marinis, the largest canyon in the solar system? It's so wide that from one side, the opposite rim would be below the curve of the horizon. Still, you'll catch some spectacular blue sunsets in the Normally red sky, 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, curiosity, or are you just looking for opportunity? Then stop stalling and make the move to mars today, mars, rather than ever. 哔哩哔哩。广阔深邃了无边际的太空往往有一种神秘的色彩，它的繁复与多变引发人类无限的遐想和探索的欲望。人类在对太空不断的探索中发现，如果向太空发射一颗飞行器，让它围绕地球运行，既可以观测地球万象，又能探索宇宙奥秘，进行太空科学实验。我们通常把宇宙中围绕行星按一定的轨道运行的天体统称为卫星。太阳系里的多数行星都有自己的天然卫星，比如月球就是地球的天然卫星。相对于天然存在的卫星，另一种存在便是人造卫星。顾名思义，人造卫星是由人工制造而绕行星运转的天体。比如我国由中学生参与研制的八一少年行卫星就是一颗人造卫星。人造卫星的最初想法始于1870年。多少年来，为了实现通过人造卫星遨游太空的梦想，人类进行了大量的实验，经历了无数次的挫折与失败，终于在1957年10月4日由前苏联成功发射了世界上第一颗人造地球卫星斯普特尼克一号。自此，人类开创了太空探险的新旅程。轩是人类空间时代的到来。1970年4月24日21时35分，我国成功发射东方红一号人造卫星。东方红一号人造卫星的发射成功，标志着中国成为继苏联、美国、法国、日本之后，世界上第五个用自制火箭发射国产卫星的国家，为中国航天技术的发展打下了极为坚实的基础。从此，中国正式加入了太空俱乐部，进入太空时代。随着现代科技的不断发展，人类研制出了各种人造卫星，据不完全统计，目前仅围绕地球飞行的就有数千颗。 种土豆。寻找。一些东西。保卫地球。就像这个三体星人要攻击地球一样的，总有一个人类的去处。月亮上面看看有没有真的有。嫦娥之类的，把一些太空的垃圾给清理掉。意义非常大，保护着我们国家扩大中国领土，在占领一颗星球。本我想去什刹海的，通过这个导航地图我才发现，对，这离这个后海挺近的，顺便就来这溜达。能体现出咱们国家是一个。强盛的国家。There he places . and planets and galaxies. 通过这个宇宙的发射也好，整个天文学的一个系统的研究，才能开启我们对生命科学的下一步的一个认知。没有这么样一个高科技的这么样的一个实力的话，咱们国家是很难够捍卫老百姓正常的一种生活的。一些信息共享沟通的东西，是全是靠开心上的那些卫星去连接。这个潜力对将来的人类的生存和发展应该是有重要意义的。航天科技是中国人全国人民的大事。他们用的水杯子不应该是那种塑料的，必须得是那种铁的，然后还得用吸管喝，因为我们在语文语文书上就有的。 课型：听说课 Unit 6 Beyond Earth Section A Why do we explore space? 课时：3a-3c 学生可以完整听懂访谈音频，梳理清楚文本中用来解释太空探索的三层核心原因；能够区分主持人用来推进对话的语言形式；可以准确感知文本内时态的用法。（学习理解） 01 学生脱离原文内容，自主说出个性化太空探索理由，辩证思考外星居住的优缺点；能够自主创编新的简短太空访谈，把本课句式与时态灵活用在全新相关话题表达中。（迁移创新） 03 学生能仿照原文完成双人访谈角色扮演，使用访谈常用互动句式顺畅对话交流；可结对围绕探索太空的原因开展口语讨论，熟练运用本课时态句式完成基础口头表达。（应用实践） 02 教学目标 -01- Lead-in Why do we explore space?

How many reasons for space exploration are? ____________________________________________________ We can better understand the Earth. Because the Earth may run out of resources. Three. Read the interview and complete the mind map. 3a Host: Our question today is: Why do we explore space? Let’s talk to space scientist Dr Yang. Welcome, Dr Yang! Dr Yang: Thank you very much. Well, there are three good reasons to explore space. First, to improve our knowledge of Earth and its place in the universe. Host: Could you explain that a bit more? Dr Yang: Sure. The study of other planets helps us better understand Earth’s geology, history, and relationship with other planets. Host: Oh, right. Dr Yang: Second, technology developed for space can benefit us here on Earth. Host: Could you give our listeners an example? Dr Yang: Of course. Some satellites, for example, help us deal with problems caused by climate change. Host: Yes, that’s very useful. And the third reason? Dr Yang: Well, at some point in the far future, we may find new resources in outer space. It might sound crazy, but our Earth may run out of resources. In that case, a new home for us human beings will be needed. Host: Wow, interesting! Maybe Mars will be made into our new home in the future. Read the interview and complete the mind map. 3a better understand Earth’s geology, history, and relationship with other planets benefit people on Earth and help solve real-life problems such as climate change with satellites find new resources in outer space and get a new living home for humans someday Listen to the interview. Pay attention to how the host keeps the interview going with questions and comments. Then role-play the interview. 3b Host: Our question today is: Why do we explore space?

I think space travel can encourage teenagers to learn science and engineering. . . . Q: Do you agree that humans should move to live on Mars someday? Give your opinion with reasons. Once Earth’s natural resources are used up, new minerals and energy resources will be found on Mars. Humans will have enough materials to survive. Mars has no enough oxygen for humans to breathe. Its temperature changes greatly and strong radiation exists. People’s health will be badly hurt. Discuss the question and talk. Let’s watch and learn. -05- Language Points Language Points 增进我们对…… 的了解 探索太空 Host: Our question today is: Why do we explore space? Let’s talk to space scientist Dr Yang. Welcome, Dr Yang!
