Unit 2 CloningPart 1 Teaching Design第一部分教课方案Period 2 A sample lesson plan for Learning about Language (Revise the Appositive <words||，phrases and clauses>) IntroductionIn this period students will be first helped by the teacher to discover and learn to use some useful words and collocations|| ， and then to discover and learn to use the following useful structures: the appositive <words||， phrases and clauses>. The following steps of teaching may be taken: warming up by reading aloud to the tape the text CLONING： WHERE IS IT LEADING US?；learning about appositive； building up on your word power ； discovering useful words and collocations ； discovering and distinguishing ； closing down by talking about cloning.ObjectivesTo help students revise the Appositive <words|| ， phrases and clauses>)To help students discover and learn to use some useful words and collocationsTo help students discover and learn to use some useful structuresProcedures1.Warming up by reading aloud to the tape the text CLONING： WHERE IS IT LEADING US?2.Learning about appositiveWhat is an Appositive?An appositive is a noun|| ， noun phrase||， or noun clause which follows a noun or pronoun and renames or describes the noun or pronoun. A simple appositive is an epithet like Alexanderthe Great. Appositives are often set off by commas.Example: We visited the home of Harriet Beecher Stowe|| ， the author of Uncle Tom's Cabin. (The underlined portion is the appositive.)Appositive PhrasesAn appositive phrase is a type of noun phrase that follows the noun or pronoun it modifies andamplifies or restricts its meaning.Our monitor||， a careful reader and outspoken critic ||， will examine the article before it is handed to the headmaster. [The italicized phrase is an appositive.]Appositive phrases are similar to relative clauses; to avoid wordiness|| ， relative clauses can often be reduced to appositive phrases.3. Building up on your word powerTo build up on your word power you are to make sentences with the collocations from the text: CLONING ： WHERE IS IT L EADING US? You may try to include as many uses of the Appositive <words|| ， phrases and clauses> as possible.1.This is a way of learning English|| ， the most popular language in the word.2.People in the future will make an exact copy of themselves.3.We may grow human beings in a laboratory in the near future.4.They are identical in sex and appearance.5.This mysterious thing is produced from coals.6.The natural clones of these plants have two major uses||， one for eating||， one forreproduction.7.At all the time|| ， producing commercial quantities of concrete things is difficult.8.We are going on with our research on the cloning of animals.9.The determination and patience of students will be rewarded with a breakthrough in cloning.10.Following the progress of English development we shall come to a conclusion that thisworld language is becoming simpler in sentence structure.4. Discovering useful words and collocations.A collocation is two or more words that often go together. These combinations just sound "right"to native English speakers|| ， who use them all the time.Now you may go to page 13. Finish the four words and collocations exercises in groups of four.5. Discovering and distinguishingTo find out and write down all the examples of the Appositive <words||，phrases and clauses>) you are to read the text Cloning: Where is it leading us?The fact that she seemed to develop normally was very encouraging ．Then came the disturbing news that Dolly had become seriously ill.Altogether Dolly lived for six years||， half the length of the life of the original sheep.Some more examples of the AppositiveMr. Smith|| ， our new teacher||， is very kind to us.Yesterday I met Tom||， a friend of my brother's.He himself told me that his brother John is a world-famous doctor.Yesterday I talked to my English teacher|| ， Mr. James.We Chinese people are brave and hardworking.He is interested in sports||， especially ball games.There are differences between appositive clauses and attributive clauses.●同位语从句只是出此刻belief||， conclusion||， doubt||， fact||， hope||， idea||， knowledge||，law||， message||， news||， notion||， order||， proof||， rumor||， sign||， suggestion||， theory||，thought 等抽象名词的后边 ||，用于进一步说明或解说该名词的内容 ||。

Unit2 CloningReading: CLONING: WHERE IS IT LEADING US?教课方案一、教材剖析本单元以Cloning 为话题，旨在经过单元教课，使学生认识克隆技术的优弊端，学会表达和支持个人看法，能用所学的相关Cloning 的词汇去表述自己对这一新技术的看法和见解。
”阅读”（ Reading）部分供给的资料CLONING: WHERE IS IT LEADING US?是一篇介绍克隆技术的说明文, 详细介绍了植物与动物克隆的差别，多利羊的出生与死亡及由此引起的争辩。
帮助学生进一步认识克隆的意义在于解决医学上的难题，为人类服务。
从话题内容上剖析，Warming Up与Reading相一致，从教材份量来说，可将Warming Up 和 Reading 整合在一同，设计成一节任务型“阅读课（精读课）”。
二、学情剖析我所带的两个班级的学生英语基础一般，平常较少阅读科学题材的文章, 知识面相对狭小，阅读理解这篇文章仍是有必定难度。
但学生的好奇心和学习接受能力比较强，能够部署学生课前上网或去图书室找出一些相关克隆的资料，并与多媒体相联合简单介绍克隆及克隆技术的一些知识，让学生有了必定的知识准备以利于很好的理解课文。
三、设计理念及教课目的这节课的主要目的是培育学生跳读和细读的阅读技巧，使学生学会正确剖析阅读问题，懂得从文章中找到要点句子摄入必需的信息，找出正确的答案。
我运用多媒体和学生搜寻资料主动参加学习相联合，设计了表格、问答题、判断题和信息整理题。
这不单提升学生的阅读技巧，也教会学生如何办理不一样的阅读问题。

Learning ability goalsHelp the students learn how to express their opinions.Teaching important pointsLearn to use the structures of expressing and supporting an opinion.Teaching difficult pointsHow to give a speech.Teaching methodsCooperative learning.Teaching aidsA computer & a projector.Teaching procedures & waysStep Ⅰ Lead-inT: Good morning / afternoon, boys and girls!Ss: Morning Mr...T: Last class we have talked about clone, we all know it is not a dream. Now everyone, if I give you a chance to clone what will you restore then?S: Edison, dinosaurs, Japanese wolf, Einstein.T: Do you want to clone Hitler?S: No. Hitler is a dangerous person.T: If some terrorists master this clone method, they may bring disasters. All your choices are excellent. Today we will learn another passage about cloning, from which we will know whether we can bring dinosaurs back to life.Ask the students to go through some facts of cloning.T: From these facts we know human beings have achieved great progress in cloning. Now read the text carefully to get the answers for these questions: what animals have people cloned?S: Frogs, mice, cows, sheep, bisons, cats, and dogs.T: Good job. Answer the question: What are the common characteristics of these animals?Ss: They are nowadays animals.T: Yeah, I think you must have seen the film Jurassic Park, in which a scientist clones several different kinds of extinct dinosaurs. Can we really clone dinosaurs now?Let the students turn to page 15 and then read the text quickly. Several minutes later. S: We cannot clone dinosaurs, because it’s difficult for us to get its DNA.T: Good job. It’s only a dream. Dinosaurs disappeared 65,000,000 year s ago. So the chance of dinosaurs ever returning to the earth is merely a dream.Step Ⅱ Read and answer (P16)To answer these three questions, teacher can give the students some examples as explanation, for example, Question 1.T: Now think about this question: if in the world there is only one sheep and human beings want to clone more. Some days later a Dolly appears, then many more. But one day all sheep get the same deadly disease. Now please think about what the results are. S: Maybe they would all die.T: Why?S: Because all sheep have the same arrangement of genes.T: Right. Now ca n you answer Question 1? Why shouldn’t you clone an extinct animal unless there is enough diversity in the group?S: It is useless to clone an animal if there is not enough diversity in the group for it to overcome illnesses.T: Why is it wrong to clone an extinct animal if it would have to live in a zoo?S: If the cloned animals have to live in the zoo, it is unfair to them. They need freedom.T. Why can’t you clone the DNA of animals that have been extinct longer than 10,000 years?S: Dinosaurs disappeared 65,000,000 yeas ago. So the chance of dinosaurs returning to the earth is merely a dream.Step Ⅲ Discussion (Question 2)This is a speaking task. Ask the students to have a discussion in groups, organize theirwords properly, and give vivid description of the chosen animals.T: Now look at the table on page 16, discuss in pairs which extinct animals described are worth restoring by means of cloning. Choose one animal and use the information to help you argue why this animal should be restored to the earth.Give the students six minutes to discuss.S1: I think Great Auk is a wonder. Because it is a very large bird that cannot fly. The useful thing about it is that its feather doesn’t absorb water. I think if we wear clothes made of its feather, we will not worry about rain.S2: I agree with you. But I am happy to accept Dodo bird because it is friendly and not harmful. I like gentle animals. It can also lay large eggs and its meat is tasty, but I don’t think I will eat its meat.…T: From your answers I think these animals are all useful and they all should be restored to the earth. At the same time, we should try our best to protect them. Do you agree with me?S: Yes.Step Ⅳ Writing a report (P17)Deal with Questions three and four. Divide the whole class into four groups. Then they can have a competition.T: Now everyone, imagine all of you are owners of your chosen animal. Now work together, and give us a vivid description of your pet, then I will decide which one is the best to be resorted to the earth.Several minutes later, the students give performances. At the same time, list some major points on the blackboard.T: Well done everyone. It is really hard for me to choose, let us vote OK?Step Ⅴ TALKING (P55)Ask the students to talk about the questions with the teacher’s help.T: Look at the questions on page 54. Do you know how to show your opinion? You can discuss the following questions with your partner and use these expressions on page 54.1. How would you feel about having a clone of yourself in the family?2. What problems did you have growing up and how can you help him / her avoid them.HomeworkT: Write down your feelings and attitudes towards clone. Combine them into a composition.Sample version 1:In my opinion it is wrong to clone human beings. If my parents decide to have a clone made of me, I will feel very sad and I will never accept the clone as a member of my family or as my friend because I think it is unfair to natural things.We are all sons of nature, birth or death is a natural thing. The day we born, itdestined we are independent. Nobody has the right to change ourselves. If one day I were to be cloned to another person, he would kill me, because I lost some original characters. I hope we should respect human beings, and not change any original things.Sample version 2:I think the cloning represents the progress of the mankind. But it still has many problems to work out, the law, the ethic and especially the goals and purposes for cloning. However, we are actually doing much of this research for the improvement of life for humans. We should get benefit from cloning.In China, the government has put out written policy on human cloning. It has officially banned research on human cloning for reproduction purposes, but allows cloning on embryonic stem cells and remedial cloning. As we all known, everything can’t be perfect. We should treat the cloning with correct attitudes. We should know the advantages and disadvantages of cloning.。

选修8 Unit2 Cloning-Reading 教学设计与反思
3. 教学手段：
本节课采用白板教学，采用音乐、图片、视频与文字相结合的方式，既增加课堂的信息量，又调动学生的学习兴趣，并能在解决重点、突破难点方面起到辅助作用
设计依据：现代英语教学强调在“用中学”，因此创设语言环境对语言习得起着重要的作用。
同时，通过电脑课件展示相关的图片，视频，或静态，或动态，以直
观的效果激发学生固有的背景知识，在学生固有的背景知识和文本信息之间
搭建起理解桥梁，能有效地帮助他们获取信息，达到理解信息的目的。
【教学过程】
教学过程设计读前（3’）：了解相关知识
共分三部分：掌握主旨和段落大意（略读和寻读）
读中（30’）获取特定信息（细读）
积累运用（巩固）
读后（12’）：知识迁移
Step1 Lead- in
1)
在课前播放一段克隆羊多利出生的视频，问学生
was a ______ sheep.
2. When was the cloning of Dolly the sheep born?
由此引出克隆这个话题。
2）展示Dolly the sheep(多莉羊)、?A strawberry ?plant(草莓植物)、 Twins（双胞胎婴儿）的图片，让学生讨论并说出它们之间的不同点。
which ones are natural clones and which ones are man?–?made?
S: I think the twins are natural clones and the Dolly sheep is man-made. T: You are right! Can you explain how they differ?
S: The twins were born at the same time, but the Dolly sheep is man-made.【设计说明】克隆技术是一门前沿科技，学生对此兴趣浓厚，利用视频和幻灯片展示当今克隆技术产生出来的动植物照片，学生的兴趣被瞬间激发，注意力高度
集中，学习的热情高涨。
这就为进一步的学习做足了铺垫。
Step2 Fast reading
Give the students 3’to read the whole text silently and finish the two tasks
1.What’s the passage mainly about?
2.According to the main idea, divide the whole text into 4 parts.
教学反思：
由于学生阅读技巧的训练比较欠缺，平时受到抑远胜于扬。
而Unit2 Cloning又是一篇介绍克隆技术的说明文，专业性强，文中生词多，学生理解难度大。
根据这些特点，本单元我以训练阅读技巧之略读和扫读为主，并鼓励学生多思考，多发言，增强他们的信心。
在教Reading部分，在课堂教学中我借助克隆相关图片，知识及Dolly的信息导入课文，再以复习生词进入课文。
授课中始终围绕读，重在培养学生阅读技能，以skimming，careful?reading和comprehending等循序渐进式的阅读教学方法，促使学生积极配合，收到了良好的学习效果。
