优质高二英语人教版选修8教案：Unit2CloningPeriod4 Word版含解析

Unit 2 CloningPeriod 4 Listening and Speaking整体设计教学内容分析The emphasis of this period will be placed on listening and speaking.There are altogether two texts for the students to listen to in this period：one is on Page 17 in the Student's Book and the other is on Page 57 in the Workbook.The first one is a conversation between two people，Xiao Qing and Rachel.They expressed their ideas about cloning in the conversation.It includes examples of the focus function for this unit：acceptance and refusal.While listening to the dialogue for the first time the students are asked to decide which statements in Exercise 1 are mentioned in the conversation.Then students are required to listen to the tape again and then work with a partner to fill in the chart.The aim of the listening is for students to examine the issue of whether experimenting with animals is cruel or not.This is a moral issue which many people feel very strongly about.So give students a chance to think of their own points of view and make sure they have enough time to do Exercise 3.This will make sure this topic is examined fully.The second one involves cloning mammals.This is an opportunity for students to recognize the issues.This is a lighthearted discussion but it hides some truths.Ask students to listen to the tape and enjoy the story.They will feel it is very interesting.三维目标设计Knowledge and skills1．To understand the meanings of the following key words and expressions while hearing them on the tape：approve of（赞成；满意），reasonable（合理的），unnatural （不自然的），bison（野牛），procedure（过程），stem cell（干细胞）．2．To enable the students to understand the listening texts.3．To help the students learn how to express their acceptance and refusal.Process and methods1．Smoothing away language problems if any before listening.Before asking the students to listen to the tape，help them smooth away any language problems such as new words and expressions that they may not understand while listening.2．Listening for needed information.Before asking the students to listen to the tape for the first time give them one or two questions about the general idea of the text so as to lead the students to concentrate their mind only on the needed information.Then ask them to listen to the tape for a second or even a third time for some specific information by giving them some detailed questions to answer.3．Speaking freely and making conversations.At last the students may be asked to give their own points of view and attitudes towards the subject mentioned in the text.Emotion，attitude and value1．To stimulate students' sense of communication and cooperation.2．To develop students' ability of enjoying language beauty.教学重点、难点1．The understanding of the conversations on the tape.2．The expressions of acceptance and refusal.教学过程Step 1Revision1．Check the answers to the exercises about grammar.2．Check the last period's homework and explain the difficult ones.Step 2Prelistening1．Before asking the students to listen to the tape，help them to smooth away any language problems such as new words and expressions that they may not understand while listening：approve of（赞成；满意），reasonable（合理的），unnatural（不自然的），bison（野牛），procedure（过程），stem cell（干细胞）．2．Ask students the following questions：（1）What is your favorite pet？If it dies，what can you do?（2）Do you think cloning is cruel to the animals？What problems arise when scientists make an animal cloning?Step 3Listening（P17）1．Listen to the tape and tick those that you hear（Exercise 1 on Page 17）．Read the statements before listening.2．Listen to the tape again and then work with a partner to fill in the chart （Exercise 2 on Page 17）．Suggested answers：1．13452．Rachel's ideas about cloning Xiao Qing's ideas about cloning1 cruel to animals 1 scientists are doing a wonderful job2 makes the animals do unnatural things 2 may bring people's favourite pets back to life3 it is a “dead end” 3 problems because it is a new science4 weakens the species 4 it may provide cures for serious illnessesStep 4DiscussionAsk the students whose ideas they agree with.Let them get ready to have a class discussion，think about the reasons for their points of view and use their own ideas as well as those in the text.When they discuss they can use the expressions on Page 18 to help them.Sample dialogue：A：I agree with animal cloning.I think we must keep the humans safe so animals are needed to test things first.B：No，I can't agree with that because animals are alive，too.Don't they deserve a good life?C：I agree with A because we don't know if cloning is safe for humans unless we try it on animals first.D：How can you believe that？B's argument is correct.If we make animals live unnatural lives and do unnatural things，then it won't be good for them or us.A：But the scientists are trying their best to make things better for the animals.They want them to have as natural a life as possible.Your ideas are not reasonable.Unless we try things out on animals，cloning may not be safe for human beings.C：Your arguments have convinced me，A.I will vote with you.D：B's arguments sound more encouraging to me.I support a better life for animals used in cloning experiments.B：Thank you D．Thank you for your support.Step 5Listening task（P57）1．LeadinginDivide students into four groups and discuss the following questions：（1）Is it more important to use this technology to clone animals or to cure people with serious illness?（2）Should it only be available to people who can pay?（3）Should
