Unit4 Astronomy: the science of the starsReading: How Life Began on the Earth InterpretationGood 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 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? Are you interested in science? Do you know how earth began to form?Purpose of my design: (1) to catch Ss’ attention abou t the class/topic/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 ___________________ …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)(4)What did the water vapour and gases form?(5)What appeared as the earth cooled down?(6)(7)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?4.5.What life developed next on land?6.7.What life developed after forests appeared?8.What life developed after dinosaurs?9.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 the story /Sum up the passage in Ss’ own words according to the chart.Task 2.

Using languageStep1. Lead inT: We have learnt a lot about astronomy, have you got interested in it? If you are going to study astronomy, what problem will you face most?S2:Gravity.T: What is gravity?S3: Everything will fall back to the earth if it is dropped or thrown away. The pull of the earth is called gravity.T: Quite right. Who first got the idea of gravity?S4: Isaac Newton.T: How did he get the idea?S5: One day he was sitting under the tree. He saw an apple fall, which made him get the idea. Besides Newton, are there any other scientists who made a great contribution to the idea of gravity?S6: Albert Einstein, Stephen Hawking.T: How did each of them think of gravity? Or did they share the same idea of gravity? Come on, the tape will tell you.Step 2 Listening1.Listen to the tape and choose the best main idea of the listening passage (Ex.2 P30).Main idea: ①I heard about how three men made mistakes when they tried to describe gravity.②I heard about how three men wanted to find out about the beginning of the universe.③I heard about how the idea of gravity has developed over a long period of time.④I heard about three scientists and their work.The best answer : ③2.Listen to the tape again and fill in the chart in Ex. 1 on P30.(Note: Astronomers and scientists think that a black hole is a region of space (not a thing) into which matter has fallen and from which nothing can escape —not even light. So we can’t see a black hole. A black hole exerts a strong gravitational pull and yet it has no matter. It is only space - or so we think.)Step3.Reading1.Fast readingT: All the three great scientists Newton, Einstein and Hawking played an important role in the development of ideas of gravity. Would you like to know more about gravity?Ss: Yes.T: Is the moon’s gravity the same as that of the earth?S1: No.T: Read fast to see how many times would the force of gravity change?S2: Three.2.Careful readingT: What are the three times? How would the force of gravity change?T: Good! I am sure you must know more about the gravity. Suppose you are asked to make a summary about the trip, will you try? You only need to fill the blacks and the first word has been given.Last month I visited the moon with my friend. Before we left, I was told the force of gravity would change three times on our journey. Then we took off. As we left the earth, I became very heavy. Gradually the weight lessened. When I was in space, it disappeared. We floated weightlessly in the cabin and I cheered up. When I was on the moon, I was surprised to find out even walking needs lots of practice now that gravity changed. The returning of the earth was very frightening. We were amazed to watch fire break out on the outside of the ship.Step4. Reading taskT：Great! But just imagine that the moon has great gravity, then what will happen?S3: It will pull us.T: Right, maybe when we are approaching it, we will be caught in it. So let’s come to the black hole.T: What are in the black hole?S: A large circle of lights going round an empty space.T: What is the circle of lights?S: Large stars.T: What is the empty space like?S: It looks like a mouth needing to be fed.T: How did they feel?S: They watched in shock and amazement as a large sun suddenly disappeared into the hole.T: So what did they decide to do?S: They decided to turn the spaceship away from the hole .T: What was happening?S: not move--- jump and move around the edge of the outside of the hole--- pulling us slowly into its “mouth”--- go faster and faster.T: What did the author feel?S: feel sick, the watch moves slower and slower, my mouth dry, close my eyes.T: It seemed that they would be caught by the gr avity of a “black hole”.But what happened later?S: jump again--- increase its speed--- as fast as light--- flew like a bird.T: This time, how was the author affected?S: was bumped and banged--- able to look around us--- the computer started working again.T: What did the author feel?S: Exciting.T: Why?S: They realized that they had discovered something new about “black hole”---- They “eat’ some objects but “spit” other objects out.Step5. Homework1.Search for more about the black hole.2.Read these two passages again to find out how to organize a story.。

Using languageStep1. Lead inT: We have learnt a lot about astronomy, have you got interested in it? If you are going to study astronomy, what problem will you face most?S2:Gravity.T: What is gravity?S3: Everything will fall back to the earth if it is dropped or thrown away. The pull of the earth is called gravity.T: Quite right. Who first got the idea of gravity?S4: Isaac Newton.T: How did he get the idea?S5: One day he was sitting under the tree. He saw an apple fall, which made him get the idea. Besides Newton, are there any other scientists who made a great contribution to the idea of gravity?S6: Albert Einstein, Stephen Hawking.T: How did each of them think of gravity? Or did they share the same idea of gravity? Come on, the tape will tell you.Step 2 Listening1.Listen to the tape and choose the best main idea of the listening passage (Ex.2 P30).Main idea: ①I heard about how three men made mistakes when they tried to describe gravity.②I heard about how three men wanted to find out about the beginning of the universe.③I heard about how the idea of gravity has developed over a long period of time.④I heard about three scientists and their work.The best answer : ③2.Listen to the tape again and fill in the chart in Ex. 1 on P30.into which matter has fallen and from which nothing can escape —not even light. So we can’t see a black hole. A black hole exerts a strong gravitational pull and yet it has no matter. It is only space - or so we think.)Step3.Reading1.Fast readingT: All the three great scientists Newton, Einstein and Hawking played an important role in the development of ideas of gravity. Would you like to know more about gravity?Ss: Yes.T: Is the moon’s gravity the same as that of the earth?S1: No.T: Read fast to see how many times would the force of gravity change?S2: Three.2.Careful readingT: What are the three times? How would the force of gravity change?3.SummaryT: Good! I am sure you must know more about the gravity. Suppose you are asked to make a summary about the trip, will you try? You only need to fill the blacks and the first word has been given.Last month I visited the moon with my friend. Before we left, I was told the force of gravity would change three times on our journey. Then we took off. As we left the earth, I became very heavy. Gradually the weight lessened. When I was in space, it disappeared. We floated weightlessly in the cabin and I cheered up. When I was on the moon, I was surprised to find out even walking needs lots of practice now that gravity changed. The returning of the earth was very frightening. We were amazed to watch fire break out on the outside of the ship.Step4. Reading taskT：Great! But just imagine that the moon has great gravity, then what will happen?S3: It will pull us.T: Right, maybe when we are approaching it, we will be caught in it. So let’s come to the black hole.T: What are in the black hole?S: A large circle of lights going round an empty space.T: What is the circle of lights?S: Large stars.T: What is the empty space like?S: It looks like a mouth needing to be fed.T: How did they feel?S: They watched in shock and amazement as a large sun suddenly disappeared into the hole.T: So what did they decide to do?S: They decided to turn the spaceship away from the hole .T: What was happening?S: not move--- jump and move around the edge of the outside of the hole--- pulling us slowly into its “mouth”--- go faster and faster.T: What did the author feel?S: feel sick, the watch moves slower and slower, my mouth dry, close my eyes.T: It seemed that they would be caught by the gravity of a “black hole”.But what happened later?S: jump again--- increase its speed--- as fast as light--- flew like a bird.T: This time, how was the author affected?S: was bumped and banged--- able to look around us--- the computer started working again.T: What did the author feel?S: Exciting.T: Why?S: They realized that they had discovered something new about “black hole”---- They “eat’ some objects but “spit” other objects out.Step5. Homework1.Search for more about the black hole.2.Read these two passages again to find out how to organize a story.。
