Unit 4 Astronomy：the science of the stars 【美文阅读】关于大地起源的神话有许多许多，你了解多少呢？The sky and the earth were at first one blurred entity(混沌整体) like an egg. Then Pangu was born into it. The separation of the sky and the earth took eighteen thousand years. The yang which was light and pure rose to become the sky，and the yin which was heavy and murky(黑暗的)sank to form the earth. Between them was Pangu, who went through nine changes every day, his wisdom greater than that of the sky and his ability greater than that of the earth. Every day the sky rose ten feet higher, the earth became ten feet thicker, and Pangu grew ten feet taller. Another eighteen thousand years passed, and there was an extremely high sky, an extremely thick earth, and an extremelytall Pangu. After Pangu died, his head turned into the Five Sacred Mountains(Mount Tai, Mount Heng, Mount Hua, Mount Heng, Mount Song), his eyes turned into the moon and the sun, his blood changed into water in river and sea, his hair into grass. In all, the universe and Pangu combine in one.【诱思导学】1．Do you agree on the forming of the universe？Give your reasons.________________________________________________________________________________________________________________________________________________2．What kind of people is Pangu in your eyes?________________________________________________________________________________________________________________________________________________【答案】 1.No，I don't agree.Because the scientists have already found out how the universe formed.2．I think Pangu is very great and determined.He is a hero.Period ⅠPreviewing(教师用书独具)●教学目标本课时主要是通过学生对学案所给出的内容的学习，了解本课文中所出现的词汇，初步了解课文以及相关的背景知识，就下一堂课对课文的全面理解起到一个铺垫作用。

Book 3Unit 4Astronomy：the science of the starsⅠ.阅读理解(2019·重庆巴蜀中学期中)Scientists have found living organisms trapped in crystals(晶体) that could be 50,000 years old.The organisms were found in a hot，but beautiful cave system in Naica，Mexico.These ancient life forms can be seen only with a microscope.Penelope Boston，who leads the Astrobiology Institute at NASA，the space agency of the United States，says the ancient microbes were able to live by eating minerals such as iron.She spoke about the discovery recently at a meeting of the American Association for the Advancement of Science.If the findings are confirmed，they will show how microbes can survive in extreme conditions.Forty different kinds of microbes and some viruses were found in the underground area.The genetic structures of these organisms are 10 percent different from those of their nearest relatives.The caves in Naica are 800 kilometers deep.They were once used for mining lead.Before the miners began working in the caves，the area was separated from the surface and the outside world.Some of the caves are as big as the large religious centers built during Europe’s Middle Ages.There are crystals covering the walls.The caves are so hot that scientists must wear special clothing to keep cool.The clothing keeps the crystals safe from human germs(病菌) or other damage.Boston said the researchers could only work for about 20 minutes at a time before they had to go to a room that was 38 degrees Celsius to cool down.NASA officials would not let Boston share her findings with scientific experts before last week’s announcement.So scientists could not say much about the findings.But Norine Noonan，a biologist with the University of South Florida，said she believed them.“Why are we surprised？”Noonan asked.“As a biologist，I would say life on Earth is extremely tough and extremely colorful.”Boston is also studying microbes commonly found inside caves in other countries，such as Ukraine and the United States.These microbes appear to be impossible to kill.Boston said they show how difficult life on Earth can be.1.The existence of the ancient microbes relies on .A.surrounding insectsB.eating mineralsC.diverse plantsD.absorbing air答案B解析细节理解题。

Astronomy：thescienceofthestars教材分析

“语言运用”（Using Language）由Listening and discussing、Reading和Speaking and Writing三部分交互组合而成。指导学生在听和读的输入性学习之后，完成说和写的输出性应用练习。Listening的内容介绍三位科学巨匠。不仅通过听力填表的形式训练学生捕捉细节的能力，还通过三选一的方式帮助学生找主题思想。在解释对与错的过程中，教师可以适当的介绍一下概括主题的方法。Reading是一个科幻小故事，通过作者和作者的朋友乘宇宙飞船登月球的经历，介绍了重量、失重和地球引力等科学道理。Speaking以Visiting the moon为话题，要求学生讨论登月球需要携带的物品和在月球上可能遇到的困难。Writing要求学生找出登月球可能遇到的三个困难并找出克服这些困难的方法。在听说读写综合提高的同时，培养了学生的创新意识和实践能力。
“理解”（Comprehending）部分通过五个练习题检测学生对本文核心内容的理解。练习1是对文章结构的分析以及大意的概括；练习2通过排序的方式帮助学生弄清本文的行文线索，也就是地球上生命的起源和发展历程；练习3提出5个小问题，考察学生的深层理解和推理判断能力；练习4让学生找出文章中出现的连接词，检查学生对文章中句型的熟悉和理解程度，同时还有助于学生在写作方面得到提高；练习5让学生回答问题并向全班学生汇报，开拓学生的思维并锻炼他们的语言表达能力。
“阅读”（Reading）讲述了地球上生命的起源。水的形成使得地球有别于其他星球，它使得地球上生命的诞生成为可能。科学家认为，地球上的生命首先诞生于水中，上百万年后，陆地上才长出绿色植物，随后出现了陆栖动物和水陆两栖动物。最初的动物靠孵化繁衍后代，后来出现了哺乳动物，人类也随之诞生了。文章最后讲了令人深省的问题：The earth may become too hot for the lives on it它关系到了地球的未来.

Recently, students in our class have had a discussion on whether space is worth exploring.30% of us think space exploration is not worthwhile. They think space istoo far away from us and our daily life. And the money spent on space exploration ca n be used to solve the earth’s problems such as starvation and pollution.On the other hand, 70% think space is worth exploring because we have benefited a lot from it, such as using satellites for communication andweather forecast. What’s more, with further space research, we may solve the population problem by moving to other planets one day. Also, space researchwill enable us to find new sources to solve the problem of energy shortages on the earth.翻译：最近，我们班的学生们就太空是否值得探索进行了讨论。
