2019-2020学年高中英语人教版必修三Unit 4 Astronomy: the science of the stars Ｉ．单元教学目标II．目标语言III．教材分析与教材重组1. 教材分析本单元以astronomy: the science of the stars, the development of life, space travel and gravity为话题，通过本单元的几篇阅读材料使学生对以上问题有所了解，并通过文章中的一些探讨性的问题，比如，The earth may become too hot for the lives on it. Then what will our future be? 使学生更好地了解我们的地球和我们的生活环境，并引发对“地球的将来如何”的热烈讨论，通过这些讨论激发学生对天文学了解和探究的强烈兴趣。
通过讨论登月球需要的物品和可能遇到的困难学会提出问题和解决问题的表达方法，并能就此写出一篇表达合理思路清晰的短文。
1.1 WARMING UP以讨论的形式通过三组问题引导学生讨论边缘科学，讨论科学的方法以及要成为真正的科学家所必须掌握的技能。
1.2 PRE-READING 主要让学生弄清楚什么是科学思想，什么是宗教信仰或文化传统。
在探讨生命起源的科学道理之前，让学生以听故事或讲故事的方式，交流有关宇宙的起源的种种传说，既有趣味性，又能调动学生的相关知识，激活学生的思维。
1.3 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.1.4 COMPREHENDING通过四个选择填空题检测学生对本文核心问题的理解：地球上生命的起源和延续需要哪些条件？随后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。
最后提出两个问题，考查学生的深层理解和推断能力。
1.5 LEARNING ABOUT LANGUAGE分词汇和语法两部分。
其中，Discovering useful words and expressions通过英文释意，短文填空，词语分类和单项选择等练习让学生在语境中掌握和运用词汇。
Grammar采用先发现后应用的学习方法。
先通过到课文中找句子，让学生认识主语从句，然后，设置一个用一手机发短信息的情景，让学生进行简单句与主语从句之间的转换练习。
最后设置情景来复习表语从句。
1.6 USING LANGUAGE由Listening、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，还通过四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。
2. 教材重组2.1 将Warming up、Pre-reading、Reading 和Comprehending四部分整合在一起上一节阅读课。
2.2 将Leaning about language和Workbook中的Using Words and expressions 以及Using Structures整合在一起上一节语法课。
2.3 听力Using language中的Listening与Workbook中Listening和Listening task三部分话题较为接近，其中Listening部分是介绍三位对地球引力的认识做出巨大贡献的科学伟人。
在提高听力的同时，为下文的Reading部分作了铺垫。
Workbook中Listening是关于轰动一时的航天英雄杨利伟的故事。
通过听力练习，让学生了解作为宇航员所需要哪些素质。
而Listening task中的听力则是向学生展示space travel 的潜在价值。
既然三部分都在谈论与Astronomy有关的内容，所以放在一起处理比较合适。
2.4 把Using Language 中的Speaking 和Workbook 中的Talking 和Speaking task放在一起整合成一节口语训练课。
这几部分涉及到本单元的功能句，指导学生学会如何思考需要的东西，怎样给别人以指示以及如何向别人问问题。
2.5 泛读是把Using language中的Reading和Workbook中的Reading task 整合在一起。
这两部分利用science fiction story向读者解释gravity和black hole.2.6 写作练习是把Using language中的Writing 和Workbook中的Writing Task 以及Project整合在一起上一堂写作练习课。

Before that I have aquestion: Where do we come from? Or we can say: Who are our ancestors?S1: Monkeys!S2: Beijing Ren who lived many years ago.S3: Reptiles.S4: Mammals.S5: Amphibians.S6: Dinosaurs.T: Very good! Can you put them in right order?S7: Amphibians, Reptiles, Dinosaurs, Mammals, Beijing Ren.T: Do you know what it was like before life appeared on earth?S8: It was full of water, perhaps.T: Before that, what was it like?S9: Sorry, I don’t know.T: Do you want to get more information? Today we’ll learn something about How Life Began on the Earth. Turn to Page 25. Let’s come to Warming up first.Step II Warming up1. Read the three questions, while the students listen and follow.2. Give the Ss several minutes to discuss the questions.3. Collect answers from the whole class.4. Check the answers while discussing.T: I’ll read the three questions for you. You should listen to me carefully. (If students don’t know how to discuss, show them an example.) For example, medicine. When someone gets serious illness, he will go to the hospital. The doctor will examine him. He will take his temperature, measure his blood pressure and give him an X-ray, or a CT. For the whole process of the examination, what kind of science has been used?S1: Biology.S2: Chemistry.T: So we can say medicine combines biology and chemistry. What about biochemistry and geophysics?S3: I think biochemistry combines biology and chemistry.S4: Geophysics combines geology and physics.T: What about astronomy?S5: Physics.S6: Mathematics.T: Very good. We should know that astronomy is a multidisciplinary subject and if we want to do some research on it, we should know many science subjects related to it. Now discuss the second question:What do we mean when we say we are studying a subject scientifically? Or what’s the correct attitude towards science?S7: We should be objective, not superstitious.T: What’s the correct way to prove a scientific idea?S8: We should design experiments to test it for several times.S9: Then we can analyze the results and draw a conclusion at last.T: Let’s sum up the answers. To study a subject scientifically, we must try to be objective. In order to test our idea, we should design experiments, then analyze the results and draw a conclusion. Now let’s talk about the third question.What are the most important skills we need to be real scientists?S10: We should be very careful.S11: Be objective and logical.S12: We should be wise enough to design an experiment and write the reports clearly. S13: We should be able to draw conclusions from the experiments and not impose conclusions on the data.T: I think you have done great work. From the discussion we know that it’s not easy to be a scientist. So you should work harder if you want to be a scientist.Step Ⅲ Pre-readingGet the Ss to discuss the questions on Page 25 with their partners. Then ask the Ss to tell their stories. Encourage the Ss to tell different stories. If they don’t know any, tell them some.T: Now please look at the slide show. And discuss these questions with your partners. Then I’ll ask some students to tell us their stories. Are you clear?Ss: Yes, Sir/Madam.1. Do you know each religion or culture has its own ideas about the beginning of the universe? Please give an example if you know.2. Do you know what a scientific idea is?After the Ss’ discussion, teacher says the following.T: Now who’d like to tell us a story? V olunteer!S1: Let me try. In China, we all know that Pangu separates the sky from the earth. T: Can you describe the story in details?S1: Sorry, I can’t remember clearly.T: Who can? Nobody? Now I’ll tell you. Look at the screen.Pangu separates the sky from the earthThe sky and the earth were at first one blurred entitylike an egg. Pangu was born into it. The separation of the sky and the earth took 18,000 years- the Yang which was light and pure rose to become the sky, and the Yin which was heavy and murky 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 18,000 years passed, and there was an extremely high sky, an extremely thick earth, and an extremely tall Pangu. Then came the Three Emperors (the Emperor of the Sky, the Emperor of the Earth, and the Emperor of the Men.)So these numbers came into existence and evolve like this. The number begins with one, becomes established at three, is completed at five, prospers at seven, and ends in nine. So the sky is ninety thousand li from the earth.Other legends about the beginning of universeThe Biblical Account“In the beginning God created the heavens and the earth. The earth was form less and empty, darkness was over the surface of the deep, and the spirit of God was hovering over the waters. And God said....”Day 1: God spoke and separated light from darkness creating Day and NightDay 2: God spoke and separated the water creating sky and oceanDay 3: God spoke and created dry landDay 4: God spoke and created the sun, moon and starsDay 5: God spoke and created living creatures in the air and seaDay 6: God spoke and created the land animals and manDay 7: God rested and blessed this day calling it HolyIndiaBrahma has created the world many times. This creation is repeated every four ages or yugas. There are four yugas in one eon or kalpa. In the beginning of each kalpa the world is a watery chaos.As Brahma thought beings were created. The demons were created by a wind from his rectum. After creating the demons he discarded his body which became night. He assumed a new body and out of his mouth came the shining gods or devas. This body was also discarded and became day. With his next body he created ancestor spirits. With his fourth body Brahma created human beings. This discarded body became the moon. With the fifth body Brahma had a strange thought and he created ogres, terrible creatures that wanted to devour the primordial sea of chaos. In shock at what he had done he then created ghouls. Finally he regained his senses and created birds, mammals, plants and all the other life that we see today.JapanIn the beginning the world was chaos until the heaven and earth separated. When this separation occurred the Three High Deities created two principles, the passive, Izanami or the Female, and the active, Izanagi or the Male. It was these two people who are our ancestors.In the beginning the heaven and the earth were one. The In (Yin) and Yo (Yang) had not been separated. All that existed was chaos in the form of an egg. This egg contained the seeds of the creation. Heaven, being made of the purer portion of the substance rose and the earth being heavier did not. As the heaven rose，the islands began to be formed. Later a strange plant grew between heaven and earth which became a great male god. Two additional male gods followed. These three wereformed by the will of heaven. Following this six deifies were formed and then Izanagi (the male ) and Izanami (the female ). Izanagi and Izanami were the first ancestors. They thrust down the jeweled spear of heaven into the sea. As they lifted the spear the liquid on the tip formed the islands of Japan.EuropeCelticThere were giants in the past. These giants were the gods. During the first winter a large giant was made from the hoarfrost. When this giant was exposed to fire he naturally melted. The body of this giant became the world. His hair became the forests. His skull became the sky. His blood produced the sea. His bones produced the mountains. In the middle of the earth on high mountains live the gods. South America IncaThe Incas worshiped a god named Pachacamac, also known as Viracocha. This god had originally risen from the water of Lake Titicaca and created the stars, planets and the moon. Pachacamac created everything, including people, out of clay. Because he felt sorry for humans, Pachacamac sent his daughter, the moon god, to teach humans how to build houses, grow crops and make clothes. The children of Pachacamac lived at lake Titicaca but could travel. When they traveled they were required to stick into the ground a golden rod they received from their father, Pachacamac. Each time this happened the humans would build a city.T: Are they interesting? Though they are interesting, they are only legends. We should believe a scientific idea. What’s a scientific idea?S2: It should be an idea coming from scientific theory.T: Quite right. Now we’ll come to Reading. That’s a scientific idea.Step Ⅳ ReadingRead the passage carefully and analyse its structure. Write down the main idea for each paragraph.Para.1: A widely accepted theory about the formation of the universePara 2: The formation of the earthPara.3: The importance of water for lifePara.4: The development of plants and animals on the earthPara.5: The arrival of humans and their impact on the earthReading and answer the questions.1. Why was the earth different from other planets?The water remained.2. Why was life able to develop on the earth but not on other planets?The water stayed on the earth but not on other planets.3. Why was it necessary for plants to grow before animals?Plants provided oxygen for animals to breathe.4. What problem is caused by human beings?They cause global warming.5. Why is it wrong in films and stories to show dinosaurs and people together?Because dinosaurs died out long before human beings developed on the earth. 6. Why do you think that humans are the cleverest animals on the earth?They are the cleverest animals because they have larger brains than any other creature on the earth so far.7. Why is it wrong in films and stories to show dinosaurs and people together?Because dinosaurs died out long before human beings developed on the earth. 8. There used to be nine planets in the solar system. Recently scientists have decided that one of them can no longer be considered a planet. Do you know the name of that planet? Do you know why they removed it?Pluto. Scientists now think it is too small to be called a planet.Analyze how life began on earth.ListeningListen to the tape for the students to follow and have further understanding of the passage.T: Read after the tape, then answer me some questions with your book closed.Play the tapeT: How did water come into being on the earth?If one student can’t answer completely, ask two or three or more students.Ss: The explosion of the earth produced water vapor, which turned into water whenthe earth cooled down.T: Why is water important on the earth?Ss: Because water allowed the earth to dissolve harmful gases into the oceans andseas.T: No.3, finish the following form.Key to the exercise:2. shellfish and all sorts of fish 5.amphibian(on land and in water)7. reptiles (on land) 8.dinosaurs(on land) 9.mammals(on land)T: That ’s all for this passage. Now let ’s deal with some language points.Passage AnalyzingChart of the textHow life began on the earthText RetellingRetell the text using about 100 words.Notes: Use the two questions and the chart to retell the passage; the possible version below can be used as a material for both retelling and dictation.Retelling:The explosion of the earth produced water vapour, which turned into water when the earth cooled down. Water allowed the earth to dissolve harmful gases into the oceans and seas. That made it possible for life to begin to develop. The arrival of small plants encouraged the development of early shellfish and all sorts of fish. Many millions of years later the first green plants began to appear on land. Later land animals appeared. Some were insects. Others, call beginning with two questions so as to arouse the readers’ strong curiosity and interest.2) The passage tells the readers the scientific idea in order of time. Water made everything possible on the earth. Then all kinds of plants and animals appeared. At last mankind rule the world, but they are not taking care of the earth very well. So the readers will think about a question carefully: What will our earth be in the future?2. Writing StyleThe text is common science writing, which tells the readers how the universe developed and how life began on the earth. It provides a scientific background to any investigation into space and it’s factual. It’s written in a formal way. And all the information is based on scientific research.3. Main IdeaThrough the writer’s clear description, we know that how life began on the earth. It’s a long and slow process. From the passage, we know that earth is the best place forhuman to live on. But humans didn’t take good care of it in the past. Now we are facing many environmental problems now. What should we human do? Everyone who reads the passage will think about this problem. We should pay more attention to taking care of our earth. Taking good care of the earth means taking good care of ourselves.Step Ⅵ HomeworkRetell the passage according to the form.Remember important language points.Second period Extensive readingRead and then describe the three ways in which gravity changed for Li Yanping and how his weight changed.1. The pull of gravity became very strong she left the earth’s atmosphere. His weight is normal.2. It disappeared when he was in space. He is weightless.3. It was very light when he was on the moon. He weighs less than on earth. Explanation (略)见课件Third period GrammarWhat part does the underlined part serve as in each sentence?A tree has fallen across the road.You are a student.To find your way can be a problem.Smoking is bad for you.“How do you do?” is a greeting.What she said is not yet known.That we shall be late is certain.It is certain that we shall be late.We can see from these sentences that a sentence serves as subject, so we call it Subject Clause.主语从句（Noun Clauses as the Subject）定义：用作主语的从句叫主语从句，它是名词性从句之一。
