全新版⼤学英语综合教程第⼆册教案Unit3Book2Unit 3 The Generation GapI. Teaching ObjectivesStudents will be able to:Students will be able to:1understand the main idea (Father meddled in children?s affairs with good intentions, but only to find his efforts unwelcome) and structure ( three settings, three scenes) of the text;2 appreciate the basic elements of a play;3 grasp the key language points and grammatical structures in the text;4 conduct a series of reading, listening, speaking and writing activities related to the theme of the unit.II. Key Points: The structure, the writing skill, and the main idea ofthe text will be the focus. Only a few words and sentences, which will be the obstacles for students? understanding of the text, will be explained in class.III. Difficult Points:Some sentences whose meanings are difficult to understand and whose structures are hard to analyze:1. Line 43: Sean and I will have a man to man talk.2. Line 45-47: And I just wanted you to know that I?ll do anything I can to help him through life?s dangero us sea.3. Line 103: My treat, I told him. And of course, he was glad to accept..IV. Teaching Materials: Power point and materialsV. Teaching Methods: Lecturing, practicing and discussing.VI. Teaching Timing: 8 sessions of classVII. Teaching Process:1st -2nd periods:Pre-reading; Teacher?s Introductory Remarks and Students? Discussion related to the topic.3rd -4th periods: While-Reading (Understanding the title of text A; Analyzing the organization of the text; Explaining Difficult sentences and language points in the text; Summing up the main idea of the text)5th-6th periods: Dealing with the exercises after Text A. Check on Ss? home reading (Text B); Post-Reading Task: Theme-Related Language Learning Tasks7th-8th periods: Listening and speaking tasks.A. Pre-reading tasks1 T asks Ss the following questions on the song The Times They Are A-changing?: ( 5 minutes)---Who should be sitting up and taking notice？Why? (parents, politicians, writers and critics should listen up, because the times are changing so fast that one can?t be content with one?s old way of life)---What does the singer think of his parents? way of doing things? ( outdated)2 Pair interview ( 23 minutes)1)T dictates to Ss the following list of questions:---When are your parents? birthdays and their wedding anniversary?---Do your parents celebrate your birthday? How about their own birthday celebration?---In your parents? eyes, what are you interested in?---In your eyes, what are your parents interested in?---In what areas do your parents want you to improve?---In what ways do you want your parents to improve?---Tell of an instance when your parents and you disagree over something.2)Ss form pairs to interview each other. If there is an odd number of Ss in theclass, one group may consist of 3 Ss. The interviewer must note down the answer from the interviewee.3)Some Ss report interview results to class.3 T may lead in to Text A by saying: As we find from our interviews, parents and children do not often see eye to eye. When parents interfere with their children?s affairs, they believe that they are doing so in the interest of their children. However, the children may not be grateful, as is the case in the play we are going to study, Father Knows Better. When you read on, I want you to bear this questionin mind: despite their complaints, the Thompson children actually love their father very much. Do you yourself show similar attitudes towards your own parents?( 2 minutes)B. While-reading tasks1 A brief introduction to play ( 25 minutes)1)T writes down on the blackboard the major components of a play: characters,settings, stage directions, language, conflicts, climax, and theme.2)Ss identify the characters in this play.3)Ss read the directions for Text Organization Exercises 1 and 2, then scan theplay to divide it into three parts. T may drop a hint: just read the stagedirections put in brackets.4)T explains the functions of stage directions: to set up stage properties in theproper place; to indicate a change in setting; to direct actors? movements, gesture, facial expression, tone of voice, etc. Then T draws the followingillustration on the blackboard:5)T invites one S to read aloud Heidi?s speech to the audience at the verybeginning of the play, then ask another S to re-create Heidi?s words into a complete and grammatical paragraph. They may refer to Writing Strategy to see the stylistic differences between speech and writing.6)T defines conflicts as the essence of a play, a clash of actions, ideas, desires orwills. It may happen in three forms: man against man, man againstenvironment, man against himself. When a conflict develops to the mostintensified point, it becomes a climax. T asks Ss to find out the form(s) of conflict in this play as they later go through the text.7)T explains that, unlike a novelist or short-story writer, a playwright can notcome forward, interrupt the action, and tell the audience what he/she means by a certain scene or explain to them what is going on in the minds of the characters. The audience must conclude by themselves what theme of the play is. T tells Ss that they will do so at the end of reading this play.2 T explains language points in Part I and gives Ss practice ( see Language Study).( 15 minutes)3 Ss sum up the main conflict in Part I. ( 3 minutes)4 T explains language points in Part II and gives Ss practice ( see Language Study).( 25 minutes)5 Ss sum up the main conflict in Part II.( 3 minutes)6 T explains language points in Part III and gives Ss practice ( see Language Study). ( 15 minutes)7 Ss sum up the main conflict in Part III.( 3 minutes)8 Ss sum up the theme of the play. ( 6 minutes)C. Post-reading tasks1. The way they are (25minutes)1)Ss form groups of 3-4, re-read Part Ⅱ. Based on it, they will come up with abrief summary of the characteristics of Mother, Father, and the children (see Text Analysis). T may give Ss the following model:“Father shows great respect for Mother. He pulled the chair for her before dinner, and obeyed her commands like …do go on?, …do get on with it?, …don?t keep us in suspense?. Besides, although Father was pleased with what he had done for Diane, he had learned from experience that his efforts were not always welcome. That way why he could quickly realize his blunder, as made clear by sentence …I do? Yes, I guess I do. I?ve…done it again, haven?tI ??2)When Ss discuss within the group, the following questions might help:---- How did Mother address Father and her children?---- How many do?s and don?ts did she use? What do they tell about her character?---- On whose side Heidi and Sean stage whisper to each other?---- What did Sean tell Father that “I do believe Diane would like to know the surprise?”---- How did Diane feel when she said “Thank you, Sean. I owe you one”?---- What were Diane?s reactions during the scene?3)Several groups report their summaries to the class.2. T guides Ss through some after-text exercises. (25 minutes)3. T checks on Ss? home reading (Text B) (3 minutes)4. Ss so Part Ⅳ: Theme-Related Language Learning Tasks. (1 period)5. T asks Ss to prepare for the next unit: (2 minutes)1)do the pre-reading task;2)preview Text A.VIII. Assignments:Assignments for 1st and 2nd periods:Vocabulary Exercises I, II, III in Text A●Listen to the recording of the textAssignments for 3rd and 4th periods:●Review what have been learned in class●Comprehensive Exercises, I, II in Text A●Read the text fluently and imitate the pronunciation and intonation of therecordingAssignments for 5th and 6th periods:●Review what have been learned in class●Language Practice in Text B●Preparations for paragraph recitation and dictation of new words andexpressions in Unit 3Assignments for 7th and 8th periods:●Review what have been learned in class●Home listening: Task 1, 2 and 3●Previewing text A in Unit 4IX. Teaching Reflection:Try to listen to the feedback of the students during and after the course, analyze the weaknesses in teaching and improve the methods as much as possible.The feedback from the students:The methods taken to improve the teaching and learning:X. Appendix: Teaching Contents:A. Text AnalysisAlthough a playwright can?t come forward to speak directly readers, we may still form a mental picture of what each character is like.Let?s take Part Ⅱfor example. From the way they speak, their tone of voice, their facial expressions and their actions, we find Father, Mother and the three Thompson children life-like.Since a brief discussion of Father?s characteristics is given as a model in the Suggested Teaching Plan, here we will focus on Mother and the children.As we notice, in her speech Mother uses quite a number of do’s and don’ts, pleases, dears, and sweetheart’s. She is the real head of the Thompson household, giving out commands to her children as well as her husband. Moreover, most times her orders are respected. On the other hand, knowing her children?s attitude towards Father?s meddling, she tries to maintain the peace, as in the in stance when she maintains Father?s dignity by telling the children “Don?t interrupt”, “Don?t distract your father”, and “give your father the respect he deserves”, or when she tries to divert the conversation by talking about her dessert.The Thompson chil dren respect Mother, as shown by their frequent “Yes, Mother” and “Sorry, Mom”. On the other hand, they are used to Father?s meddling with their affairs. When Sean and Heidi find out that this time the bad luck had befallen Diane, they can afford to stand back and poke a few bemused comments. Diane?s feelings are entirely different, though. She is put on guard when Father tells her “I have a surprise for you.” Then she is embarrassed as Father mentions her feelings toward young Kyle. Later, as Father goes on delaying telling the truth, she becomes hysterical. Finally, when she learns the truth, she loses her temper.Isn?t it a wonder that words can tell so much about people?B. Cultural Notes1.Family life: Some families are very child-centered. The closest families eat meals at the same time and spend their free time together. Some families, however, only see each other for a short time in the evening, and though the children are still considered important, they have to fit in the lives of their parents.The average day for many families begins with getting the children up and ready for school. There is usually a rush for everyone to use the bathroom, find clean clothes, eat breakfast, and catch the bus. In the meantime the parents have to get ready for work themselves. Early mornings are a scramble for many families.The school day usually ends at about 3 p.m. in the US and 4 p.m. in Britain, and the working day at 5 p.m. or later, so many parents have to make arrangements for their children after school. They may go to an after-school center or stay with a neighbor?s children. Older children often do activities like sports or music at their school, or go home and do their homework. Children often also have to do chores.In many families, the children eat when they get home and their parents eat later. In the evenings the children play or go and see friends. If everyone is staying in they may watch television together. Many parents make an efforts t spend quality time with their children, an hour or so each day when they give them the full attention.American families are often criticized for the way they do things separately, though many people believe that it is good for children to learn to be independent. From an early age children are encouraged to decide what they want to do, eat or wear, and their parents try to respect their opinions.2. Part-time job: Many American teenagers earn a good portion of their college expenses by working during the summer as waiters or waitress, construction workers, mother? h elpers, gas station attendants, telephone operators or messengers. They are not concerned with status. Being unskilled, they try to find jobs at whatever level they can. They seek not only money, but also experience. They learn work habits, responsibility, the ability to take orders and to get along with a boss and different kinds of people.C.

A computer is a machine which stores knowledge in its memory and does calculations onthat knowledge. This knowledge is stored in symbols; it is called data. A computer usually has a monitor to show results. However, some computers can speak; these computers can be used for voice mail.A computer is now almost always an electronic device. It usually contains materials whichare toxic; these materials will become toxic waste when disposed of. When a new computer is purchased in some places, laws require that the cost of its waste management must also be paid for. This is called product stewardship.Step 3. Pre-readingPurpose: To activate Ss’ interest about computers.Group workAsk Ss the following questions and encourage them to say more.1.How have computers changed our lives ?2.What do you know about computers ?Suggested Answers:1.
