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 ||。
Unit 2 CloningⅢ. 教材分析和教材重组1. 教材分析本单元以Cloning为话题，旨在通过单元教学，使学生了解克隆技术的优缺点，学会表达和支持个人观点，能用所学的有关Cloning的词汇去表述自己对这一新技术的观点和看法。
1.1 Warming Up提供了四幅有关Dolly the sheep(多莉羊)，A strawberry plant(草莓植物)，Identical dogs(克隆狗) ，Twins（双胞胎婴儿）的图片，让学生用已有的知识和经验讨论对克隆技术的看法与观点。
1.2 Listening是关于人类克隆的听力材料，难度中等。
1.3 Speaking根据材料，四人小组合作，要求把自己对克隆婴儿的态度和感觉用相关的语言表达出来。
语言要得体，锻炼语段表达能力。
1.4 Pre-reading是Reading的热身活动，它要求采用与同学讨论交流的方式谈论有关克隆的相关知识。
1.5 Reading是一篇介绍克隆技术的说明文。
1.6 Comprehending第一题所给出的表格让学生根据课文内容列举克隆技术的优缺点；第二题让学生根据所拥有的知识来评价作者的观点；第三题要求学生用自己的语言阐述对克隆技术的观点并给出理由。
1.7 Learning about Language分词汇和语法两部分，其中Discovering useful words and expressions 是根据语境在运用中掌握词汇。
Discovering useful structures 是通过阅读和补全句子来练习。
1.8 Using Language中的Reading，Discussingand writing要求学生先读, 然后再完成四个任务型的作业，即 1. 讨论并回答三个问题；2. 讨论几种已经灭绝的动物，并且讨论哪种动物应该被恢复到这个世界上，并且给出理由；3. Listening and speaking 让学生根据所听到的内容选择并列出文中人物观点。
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。
