高一英语必修三Unit 4Unit 4 Astronomy：the science of the star Reading 说课稿课题：Reading: How Life Began on the EarthI 教学内容分析本单元的中心话题是“天文学”。
本课是一篇叙述性文体,按照时间顺序主要叙述了地球上生命的起源和发展过程。
可以说科学知识含量较高，更能激发学生的学习兴趣和好奇心。
Pre-reading 部分也提出了三个问题，主要是让学生区分宗教信仰、文化传统和科学思想之间的不同。
可以以讲故事的方式让学生彼此之间分享一些有关宇宙和地球起源方面的传说或故事，这样既能激活他们的思维也能为阅读部分打下基础。
Reading 部分描写了地球上生命的起源和发展过程，具体写了由于水的形成才使得地球上生命的诞生成为可能。
科学家认为，地球上的生命最初诞生于水中。
数万年后，陆地上才长出了绿色植物，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，再之后诞生了哺乳动物，人类也随之诞生了。
文章最后讲述的现象发人深省：The earth maybecome too hot for the lives on it.它关系到地球上生命的未来。

【导语】⾼中学习容量⼤，不但要掌握⽬前的知识，还要把⾼中的知识与初中的知识溶为⼀体才能学好。
在读书、听课、研习、总结这四个环节都⽐初中的学习有更⾼的要求。
⾼⼀频道为莘莘学⼦整理了《⾼⼀年级英语优秀说课稿5篇》，希望对你有所帮助！1.⾼⼀年级英语优秀说课稿 尊敬的各位评委，下午好！ 很⾼兴有机会向⼤家展⽰⼀下我对第三册第四模块Reading and Vocabulary部分的教学设计。
（同时板书： Book3 -Module4 Reading and Vocabulary） 新课标要求我们要围绕三维教学⽬标开展教学，整合发展学⽣语⾔知识、语⾔技能、情感态度、学习策略和⽂化意识五个⽅⾯的素养，培养学⽣综合运⽤语⾔的能⼒。
根据这⼀要求，针对学⽣的实际情况，我重新整合教材完成了教学设计。
它由教材分析、⽬标和⽅法分析、过程分析和板书设计四部分组成。
第⼀：教材分析 该模块的主题是：Sandstorms in Asia（亚洲沙尘暴）。
Reading and Vocabulary是整个模块的核⼼。
它以⽂章Sandstorms in Asia为载体，为我们了介绍了亚洲（主要是中国）沙尘暴的情况。
同时呈现出了本模块的重点词汇、句型、语法和语⾔功能。
第⼆：⽬标和⽅法分析 这节课的语⾔知识⽬标有三个：⼀是识记与⾃然灾害有关的14个单词，学会运⽤4个重点单词和7个重点短语，这是基础也是重点；⼆是理解并运⽤⼀个so … that…引导的状语从句，2个动词不定式作主语的句⼦和1个即含有同位语从句⼜时间状语从句和原因状语从句的长句⼦。
这是重点也是难点；三是注意动词不定式在⽂中的运⽤，这为下节语法课的学习做了铺垫。
我把这节课的能⼒⽬标定位在：重点操练学⽣整体把握⽂章结构和捕捉细节的阅读能⼒；重点操练学⽣skimmimg 和scanning的阅读技巧。
为了实现这些⽬标，我将采⽤：分层教学、合作学习和循环⼤课堂与PWP相互穿插的教学模式。
人教版《英语》必修三Unit 4阅读课教学设计一、教材分析本单元的中心话题是“天文学”，内容涉及太阳系、地球上的生命起源、宇宙大爆炸、月球探秘、黑洞效应等，主要内容是围绕地球上生命的起源展开。
本课时整合了Warming up、Pre?reading和Reading三部分的内容, 通过动画和思维导图等方法使学生对地球上生命的起源和生物的进化有更直观的了解，并在Post?reading 部分设计了关于global warming的讨论，将阅读技能和口语技能结合在了一起。
二、教学对象分析我所任教班级学生的基础普遍薄弱，词汇量少，学习习惯不佳且课堂参与度低。
因此，在教学设计中，我结合学生的实际情况，调整教材中的知识考查方式及检测难度，使更多的学生能在教师的引导下参与到课堂活动中来，让他们经过自己的努力有效地获取信息，以增强自信心及学习英语的兴趣。
三、教学目标1. 知识技能目标通过“头脑风暴”来激发学生对太阳系、地球起源、生物进化等天文学相关问题的兴趣；通过阅读和动画设计，使学生对地球起源有基本和直观的了解；通过思维导图的设计，帮助学生理清本文的行文线索——地球上生命的起源和发展历程；通过小组竞赛的方式，让学生积极思考并回答阅读理解中的问题；通过小组讨论，使学生思考并表达自己的想法，提高说的技能。
2. 情感态度价值观通过学习本篇文章，让学生了解地球上生命的起源及生物进化的过程，培养学生对科学的兴趣，激发学生探索科学的热情，并增强学生保护地球的意识。
四、教学重点与难点1. 熟悉与天文学相关的一些单词和短语，特别是要能认读表示八大行星的单词及与地球生命起源相关的重点词汇。
2. 阅读文章，了解地球生命的起源。
五、教学过程Step 1 Warming?up （3 mins）What science subjects do you know?What is Astronomy？Astronomy is the scientific study of the universe and the heaven bodies (such as the sun, the moon, and stars), gas, and dust within it.In solar system there are eight planets, can you name them?Mercury Venus Earth MarsJupiter Saturn Uranus Neptune【设计意图】通过“头脑风暴”的形式引入该单元话题，让学生了解太阳系及其八大行星，激发学生进一步了解天文学的兴趣。
教案纸教案纸教案纸二、不定式作状语1．结果状语不定式作结果状语常表示出乎意料的结果。
常用于下列结构中：only to do; enough to do (足够做……); too ... to ... (太……而不能……); so/such ... as to ... (如此……以至于……)。
He hurried to the railway station, only to find the train had left.他匆忙赶到火车站，结果发现火车已经开走了。
He was so tired as to be unable to walk.＝He was too tired to walk.他累得走不动了．【点津】现在分词短语作结果状语常常表示“自然而然、意料之中或顺理成章”的结果。
It hasn't rained for a month, making the crops hard to grow.一个月没下雨了导致庄稼很难生长。
2．目的状语不定式作目的状语主要表示某一动作或状态的目的。
常用于下列结构中：only to (仅仅为了); in order to; so ... as to; so (such) ... as to ... (如此……以便……)He ran so fast as to catch the first bus.他飞快地跑以便赶上第一班车。
I come here only to say goodbye to you.我来仅仅是向你告别。
【点津】 1.不定式的复合结构作目的状语,当不定式或不定式短语有自己的执行者时，要用不定式的复合结构即在不定式或不定式短语之前加for ＋名词或宾格代词作状语。
He opened the door for the children to come in.他开门让孩子们进来。
目的状语从句与不定式的转换英语中的目的状语从句，还可以变为不定式或不定式短语作状语，从而使句子在结构上得以简化。
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。

It’s my great honor and pleasure to be here sharing my lesson with you.I have been ready to begin this representation with six parts. Analysis of the teaching material, the students, the teaching aims, the important and difficult points, the studying methods, and the teaching procedure.Part 1 Teaching MaterialThe content of my lesson is New Senior English for China Book_3__ Unit_4_. This unit is about_Astronomy: the science of the stars. By studying of this unit, we’ll enable students to know sth. about astronomy and science of the stars and develop the interest in_science and learning English.At the same time, let the students learn how to_use the noun clauses as the subject and distinguish the noun clauses as the subject and as the object. From this lesson, it starts with warming up, pre-reading, reading and comprehending part. (As we all know, reading belongs to the input during the process of the language learning. The input has great effect on output, such as speaking and writing.) Therefore, this lesson is in the important position of this unit. If the Ss can master it well, it will be helpful for them to learn the rest of this unit.Part2 Analysis of the studentsThe students in Senior High School, grade one have already learned English for years, they can speak and communicate with their friends in English. They are moderate, mature and sensitive. They are highly motivated in learning English and have the ability to learn by themselves. Furthermore, the topic of this unit is about astronomy, which is full of mystery, the students will have greater interest in learning it. However, the differences in english level among students is the biggest challenge. Therefore the teacher should provide enough background information to make them better understand the text. Therefore, I will adopt appropriate teaching methods to arouse their interest in learning.Part 3 Teaching AimsAccording to the new standard curriculum and the syllabus (新课程标准和教学大纲), and after studying the teaching material, the teaching aims are the followings: 1.Knowledge objects (语言目标：语音，词汇，语法，功能，话题)(1)The Ss can master the usage of the important words and expressions.(2)The Ss can use the noun clauses as the subject and as the object in the proper situation.(3)The Ss can understand the content of the lesson, talk about astronomy and get their own idea about protecting the earth.2.Ability objects (技能目标：听，说，读，写)(1) To develop the Ss’ abilities of listening, speaking, reading and writing(2) To guide Ss to set up effective studying strategies.(3) To improve the student’s reading ability, especially their skimming and sca nning ability.(4) To train the Ss’ abilities of studying by themselves and cooperating .3.Emotion or moral objects (情感目标：兴趣，自信，合作，爱国，国际视野) (1)By completing the task, the Ss increase their interest in astronomy and science and set up self-confidence in learning English and protect the earth in proper ways.(2)Teach the Ss to cooperate with others and cultivate the patriotic spirit and international visions, put the moral education in the language study.Part 4 the Important and Difficult PointsBased on the requirement of the syllabus. The important points are_new words and expressions in the text, such as theory, billion, violent,fundamental, give birth to etc. The difficult points are the usages of noun clauses as the subject and as the object, how to distinguish these two kinds of noun clauses.Part 5 Teaching MethodsAs is known to us all, a good teaching method requires that the teacher should help Ss develop good sense of the English language. For achieving these teaching aims, (after the analysis of the teaching material and teaching aims,) I will use the following methods according to the modern social communication teaching theories(现代社会交际教学理论) .municative Approach(交际教学法)2. Whole Language Teaching(整体语言教学法)3. Task-based Language Teaching (任务教学法)4. Total Situational Action (情景教学) a “scene —activity” teaching method , it establishes a real scene and the interaction between the teacher and the Ss. At the same time, CAI (电脑辅助教学) can provide a real situation with its sound and picture, it can develop the Ss creativity in learning English.Part 6 Teaching ProcedureStep1.Lead-in.(__10___min)1.Ask students to read the questions in warming up part, then discuss with their group members. After that ask several representatives to give their ideas.2. Ask students: Do you know any big events in the astronomy in history? If you know, can you tell us sth. about them?

课题：Reading: How Life Began on the Earth
I 教学内容分析
本单元的中心话题是“天文学”。
本课是一篇叙述性文体,按照时间顺序主要叙述了地球上生命的起源和发展过程。
可以说科学知识含量较高，更能激发学生的学习兴趣和好奇心。
Pre-reading 部分也提出了三个问题，主要是让学生区分宗教信仰、文化传统和科学思想之间的不同。
可以以讲故事的方式让学生彼此之间分享一些有关宇宙和地球起源方面的传说或故事，这样既能激活他们的思维也能为阅读部分打下基础。
Reading 部分描写了地球上生命的起源和发展过程，具体写了由于水的形成才使得地球上生命的诞生成为可能。
科学家认为，地球上的生命最初诞生于水中。
数万年后，陆地上才长出了绿色植物，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，再之后诞生了哺乳动物，人类也随之诞生了。
文章最后讲述的现象发人深省：The earth may become too hot for the lives on it.它关系到地球上生命的未来。
