Unit 6 Section A 3a-3c 课件 2026-2027学年人教版英语九年级上册

Our question today is, why do we explore space? Let's talk to space scientist doctor yang. Welcome, doctor 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. Could you explain that a bit more sure? The study of other planet helps us Better understand earth's geology, history and relationship with other planets? Oh, right. Second. technology developed for space can benefit us here on earth. Could you give our listeners an example? Of course, some satellites, for example, help us deal with problems caused by climate change. Yes, that's very useful. And the third reason, well. at some point in the far future, we may my 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. Wow, interesting. Maybe mars will be made into our new home in the future. 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。本来我想去什刹海的，通过这个导航地图我才发现，对，这离这个后海还挺近的，顺便就来这溜达。你能体现出咱们国家是一个强盛的国家。There's lots of a hidden places. hidden. 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海星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。 你知道人类为什么要探索外太空吗？你有过这样的疑惑吗？地球上还有很多穷人，很多地方需要花钱建设，为什么要费时费力花大价钱去探索太空呢？看完本期视频也许能为你解惑一二。大家都知道地球的可利用能源已相当稀少，在石油、煤炭、天然气等能源日渐减少的背景下，人类迫切的需要新的能源。可控核聚变就是目前已知最高效且清洁的能源。人类通过观测太阳发现了核聚变现象，并通过核聚变原理发明了核武器。而可控核聚变需要两种元素都合穿，都广泛的分布在海水中，而川在地球中非常稀有，然而骇三却可以替代穿，且没有放射性，十分安全。通过对月球探测，科学家惊喜的发现，氦三在月球的土壤中至少有120万吨，100吨氦3就可满足全全球一年所有的能源需求。如果我们能把月球的氦三全部开采回地球，那么接下来的1万年人类就无需再担心能源问题。我们抛开获取资源不谈，探索太空对我们的生活也有着巨大帮助。其实探索太空不断推进了科技的进步，笔记本电脑、无线键盘、鼠标、吸尘器、配方奶粉、净水器这些都是探索太空衍生出来的产品，还有非常多的发明是因为探索太空而衍生的，在这就不一一举例了。还有一个很重要的原因就是为了保证地球的安全。要知道在地球附近有着非常多的小行星，6500万年前，因为一颗小行星撞击地球，恐龙就此灭绝，所以我们不断的探索太空，甚至要移民到其他星球，就是担心当有小行星要撞击地球时，人类是否有足够的应对方法，看到这里是否解开了你心中疑惑呢？ We're pretty sure that mars used to have oceans, lakes, rivers, the whole package, but over time, almost all of IT throes beneath the surface or evaporated off into space. There's probably still some trapped beneath 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 one giant ocean, while the critter ridden southern hemisphere would stay mostly high and dry. That difference between hemispheres 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, is 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 gravitational pull that's about a third as strong as ours.

A host interviewing doctor yang, let's move on to see what they are talking about. Doctor yang has shared her reasons for space exploration. What about you? Do you have the same ideas or different ones? now? Work with your partner and have your own space interview. I wonder why, why are we expLoring mars? Recently, china released the first batch of scientific research results of its mars exploration mission. Among them, the jury also found water bearing minerals in plate like rocks near the landing zone, which proved there was a lot of liquid water activity in the landing zone over a billion years ago. So why are we expLoring mars out of the eight planets in our solar system? Mars has a lot in common with us. For example, one rotation of mars takes twenty four point sixty six hours, and day and night are only forty minutes longer than a day on earth. Mars also spends at a similar angle to earth. So IT also has climate changes in spring, summer, autumn and winter. Mars has an atmosphere, too. Because of the similar environment, mars has been envisions as a second home for humans, but as the exploration of mars progress, scientists decided that the planet was not suitable for human habitation. For example, oxygen, an essential element of life on earth, is very low on mars. The extreme temperature differences on mars during its twenty four point sixty six hour rotation is also one reason why humans can't live there. Man's exploration of the universe is just beginning. Perhaps in the future, we will finally find the second hearth on more distant planets. 外层空间是人类的共同疆域，空间探索是人类的共同事业。探月工程始终秉持平等互利、和平利用、合作共赢的原则，嫦娥既是中国的，又属于全人类。伟大事业孕育伟大精神，伟大精神引领伟大事业。我们要在全社会大力弘扬追逐梦想、勇于探索、协同攻坚、合作共赢的探月精神。
