2019-2020学年高中英语人教版必修三Unit4 Astronomy: the science of the starsReading: How Life Began on the EarthInterpretationGood morning, ladies and gentlemen. 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 scanning 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? Are you interested in science? Do you know how earth began to form?Purpose of my design: (1) to catch Ss’ attention about the class/top ic/passage.(2)To set up suspense/develop interest in the astronomy and the science.Step 2. Pre-readingTask 1. ( pair work, __3___min)Let Ss read the questions1-2 in pre-reading part, then work in pairs to find out the answers to the questions, then ask several students to express their ideas.Task 2. (Individual work, __2___min)Ask students to read the title and look at the pictures. Predict what the reading will be about. Then ask one student to say his/her guess.Now, let’s see what happened in the text./ let’s check whether it is right or not. Purpose of my design: (1) to get to know something about how life began on the earth.(2) To have a better understanding about the importance of protecting the earth. Step 3. While-readingTask 1. (Individual work __5___min)Skimming: Ss should read the material fast to find out the main idea/topic sentence for each paragraph.Para 1 ___________________Para 2 ___________________Para 3 ___________________ …Task 2. (Individual work, __5___min)ScanningRead the passage carefully and then fill in the blanks with different kinds of living things.Task 3. (Individual work __5___min)Scanning: Guide Ss to read the material carefully and take some important notes, then finish the exercise 2 on P27.Task 4. (Individual work, pair work, group work, class work; __5___min) Scanning: Ask Ss to read the material carefully and find out the correct answers to finish the following questions.This text can mainly divided into two stagesStage 1 : The development of the earth(para.1-3)(1)After the Big Bang, what was the earth like?(2)What happened next?(3)What did the water vapour and gases form?(4)What appeared as the earth cooled down?(5)Why is water so important for the beginning of life?Stage 2 : The development of life(para.4-5)1.What life developed after water appeared?2.What life developed in water next?3.What about the life on land?4.What life developed next on land?5.What life developed after forests appeared?6.What life developed after dinosaurs?7.What life developed after mammals?Purpose of my design: Enable students to understand the given material better by using different reading skills. And proper competition can arouse the Ss’ interest in English learning. “Task-based” teaching method is used here to develop the Ss’ ability of communication and also their ability of co-operation will be well trained.Step 4. Post-readingTask 1. (Individual work __3___min)Ask Ss to close books and finish the summary according to their notes.Retell th e story /Sum up the passage in Ss’ own words according to the chart. Task 2. (group work, __7___min)Discuss with other group members and then choose a reporter to share their opinions about the questions with the whole class.How life began on earth is one of the biggest puzzles that scientists found hard to solve.1.What other puzzles are hidden in the passage?2. According to the evolution of life on the earth, why was the earth different from the other planets?3. Can you imagine the reason why dinosaurs disappeared?4. As the earth is heavily polluted by us humans, what should we do to make up for it?Purpose of my design: I think If the Ss can finish this task well, they will benefit a lot in their spoken English. Most Ss can take their parts in the activities, especially for the Ss who have trouble in English study.Step 5. Homework1. Review the new words and expressions in the text2. Finish the exercises 1-3 on P28.Purpose of my design: Homework is so important and necessary for to master the knowledge they learned after class.

What are they?(Note:According to the present day scientific study, there are only eight planets, with the Pluto excluded.)S: The Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.T: Which planet do we live on? Can you describe what it looks like?S: Earth. It supports a variety of life and 70% of the earth is covered with seas or oceans.Step 3 discussionWhere do we come from? Or we can say: Who are our ancestors?Do you know any ancient idea about the beginning of the universe?Pangu separates the sky from the earth.The sky and the earth were at first one blurred entity like 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, 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. Now the earth was formless 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 were created. 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, or Gandharvas. Finally he regained his senses and created birds, mammals, plants, and all the other life that we see today.Step 4 appreciationPlay a video for the studentsHow many types of life on the earth have you seen in the video? Name them.Students tell everything they have seen in the video. (Present on the blackboard the new words and a general picture of the topic of this lesson.)Big Bang universe a cloud of dust globe violent atmosphere water plants cells shellfish fish land animals insects amphibians reptiles dinosaurs mammals apes(monkeys) humansStep 5 fast readingHow did life develop through history?Read fast and find out the answers.A cloud of dust →a solid ball →presenceQ: Why was it necessary for plants to grow before animals?(Plants provided oxygen for animals to breathe.)Step 6 RetellingSuppose you are Dr. … who studies astronomy. You are invited to give a speech to the school students about the development of life on “Earth Day” (April 22nd).Homework:1.Search the Internet for the information of the development of life.2.Read and learn good words, phrases or structures from Reading.Period 2 reading (2)Step 1 Scanning1 What’s the style of the text?2 What’s the main idea of the text?Step 2 skimmingFind out the main idea of each para.Step 3 careful readingFinish off the chart.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.Step 4 consolidationT or F1.The earth was a cloud of dust before it combined into a ball around the sun.2.The water vap our, carbon dioxide, oxygen, nitrogen formed the earth’s atmosphere.3.The coming of small plants growing in the water made the earth different.nd animals appeared before the green plants on land.5.Dinosaurs produced their young by laying eggs.6.The earth may become too hot if too much carbon dioxide was put into the atmosphere. Step 5 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 vapor, 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 toappear on land. Later land animals appeared. Some were insects. Others, called amphibians, wereable to live on land as well as in the sea. When the plants grew into forests, reptiles appeared for the first time. Later, dinosaurs developed. They became the most important animals on the earth for millions of years. After they disappeared, mammals became more important.
