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。

Unit 2 CloningPart 1 Teaching Design第一部分教学设计Period 3 A sample lesson plan for Using Language(THE RETURN OF THE DINOSAURS)IntroductionLanguage is learned to be used in and for communication. So in this period we shall have the students read, listen, write and speak in English, making use of the focused words, collocations, structures and topic ideas covered in this unit. The teacher may take the following steps in teaching: warming up by reading aloud the text on page 11 to the tape；Reading for forms；discussing about extinct animals；listening and talking about cloning and closing by looking and saying.ObjectivesTo help students read the passage THE RETURN OF THE DINOSAURSTo help students to use the language by reading, listening, speaking and writingProcedures1. Warming up by reading aloud the text on page 11 to the tape.Why read aloud? Because reading aloud:•Is great fun, and it benefits our growth as readers and learners.•Nurtures our love of both the written and spoken word.•Gives us a chance to rediscover favorite stories and find new ones.•Helps us develop important language skills that will help us learn to read on our own.2. Reading for formsRead the text THE RETURN OF THE DINOSAURS on page 15: cut/ the sentence into thought groups, blacken the predicates, darken the connectives and underline all the useful collocations. 3. Discussing about extinct animalsSome animals have gone for ever. Some animals are endangered. Tigers in Asia are endangered. Now in groups of four make a list of endangered animals and have a discussion of them.Endangered tigerThe tiger lives in the jungles and canebrakes of Asia. Its body markings provide excellent camouflage in long grass.This large carnivore usually hunts at night, spending the greater part of the daylight hours resting in shaded areas to escape the heat. It eats a variety of other creatures, from frogs and turtles, to cattle, monkeys, deer, buffalo, and even the occasional young elephant.Tigers are the largest existing members of the Felidae and are, on average, larger than lions, ranging in weight up to 267 kg.4. Listening and talking about cloningCloning is something which will change the direction of the world development. Now let’s listen to more cloning.Is cloning an organism the same as cloning a gene?You've heard about cloning animals --- sheep, mice, even house pets --- in the news. From time to time, you may have also heard about researchers cloning, or identifying, genes that are responsible for various medical conditions or traits.What is the difference?Cloning an animal, or any other organism, refers to making an exact genetic copy of that organism. The techniques used to clone organisms are described on this page.Cloning a gene means isolating an exact copy of a single gene from the entire genome of an organism. Usually this involves copying the DNA sequence of that gene into a smaller, more accessible piece of DNA, such as a plasmid. This makes it easier to study the function of the individual gene in the laboratory.Now you may work in pairs to put this listening material into a dialogue.5. Closing by looking and sayingLook at the photos and say something about cloning. What is it? How it done?。

Unit 2 Cloning【美文阅读】Pandas can be saved by cloning?从1998年中国科学院动物研究所首席科学家、动物克隆与受精生物学学科带头人陈大元首次正式提出克隆大熊猫到现在，整整16年过去了，陈老仍然执著于此。
然而保护大熊猫，究竟要不要通过克隆的方式呢？China has been exploring every possible means of saving giant pandas，one of the world's most endangered species，from becoming extinct，even if it means resorting to(诉诸) cloning them.Chen Dayuan，a senior scientist who specializes in cloning at the Institute of Zoology in the Chinese Academy of Sciences，introduced the idea of performing cloning techniques on giant pandas in 1998.Using initial funding of 100,000 yuan，Chen successfully produced blastocysts(胚泡) by transplanting the somatic nucleus from sample pandas into the egg cells of rabbits.The move was considered as one of the 10 biggest achievements of science and technology in 1999.It won an award of 6 million yuan and further funding of 5 million yuan for the project from the Ministry of Science and Technology.At first，two embryos were created from a surrogate mother(代母) cat who became pregnant after bei ng injected with a blastocyst，but the experiment was abandoned after the cat died.Chen and his team then experimented with surrogacy on black bears.After three years of effort，a black bear became pregnant and the shape of a fetus(胎儿) could be seen on an ultrasound scan(超声波扫描检查)．However，the research was stopped in 2005 because the fetus did not completely develop before the project's deadline.“Those who are against cloning have made their voices heard throughout the research project on cloning giant pandas.Some people believe cloning goes against nature，but it is actually a pioneering technology.If successful，it is a way to save endangered animals，”Chen said.Some scientists take a different view.“While I agree that research on cloning is meaningful，it is inappropriate to use giant pandas in this type of experiment.The number of pandas is limited and human beings have yet to master knowledge about pandas' pregnancy.Cloning would do little to save the species，”said Wang Dajun，a researcher at the School of Life Sciences，Peking University.In response，Chen said that he would continue his research.【诱思导学】1．Do you think pandas can be saved by cloning？Why?______________________________________________【答案】省略2．Why are some scientists against cloning pandas?______________________________________________【答案】Because they think cloning go against nature.Period ⅠPreviewing(教师用书独具)●教学目标本课时主要是通过学生对学案所给出的内容的学习，了解本课文中所出现的词汇，初步了解课文以及相关的背景知识，为下一堂课对课文的全面理解起到一个铺垫作用。

Unit 2 CloningPart 1 Teaching Design第一部分教学设计Period 1 A sample lesson plan for reading(CLONING：WHERE IS IT LEADING US?)IntroductionIn this period, after the warming up, students will first be guided to pre-read the text by questioning and answering. Then they shall read aloud to the recording, read for forms, read for the type of writing and summary of CLONING：WHERE IS IT LEADING US?. The students will be asked to copy useful expressions and make sentences, read and transform and read the text again to draw a diagram of it and retell the story with your own words. The period will end in students learning more about Dolly. ObjectivesTo help students understand the text’s forms and contents and learn about cloning To help students communicate on the topic in focus with the words, expressions and structures learned in this unitFocusAidsMultimedia facilities, tape-recorder, photos, diagramsProcedures1. Warming up by leaning the word “clone”clonen.1. A cell, group of cells, or organism that is descended from and genetically identical to a single common ancestor, such as a bacterial colony whose members arose from a single original cell.2. An organism descended asexually from a single ancestor, such as a plant produced by layering or a polyp produced by budding.3. A DNA sequence, such as a gene, that is transferred from one organism to another and replicated by genetic engineering techniques.4. One that copies or closely resembles another, as in appearance or function: "filled with business-school clones in gray and blue suits" Michael M. Thomas. v. cloned, clon·ing, clones1. To make multiple identical copies of (a DNA sequence).2. To create or propagate (an organism) from a clone cell: clone a sheep.3. To reproduce or propagate asexually: clone a plant variety.4. To produce a copy of; imitate closely: "The look has been cloned into cliché" Cathleen McGuigan.2. Pre-reading by questioning and answeringWhat is cloning? We define cloning as production of a cell or organism with the same nuclear genome as another cell or organism.Cloning is the process of creating an identical copy of an original. A clone in the biological sense, therefore, is a single cell (like bacteria, lymphocytes etc.) or multi-cellular organism that is genetically identical to another living organism. Sometimes this can refer to "natural" clones made either when an organism reproduces asexually or when two genetically identical individuals are produced by accident (as with identical twins), but in common parlance the clone is an identical copy by some conscious design. Also see clone (genetics).The term clone is derived from the Greek word for "twig". In horticulture, the spelling clon was used until the twentieth century; the final e came into use to indicate the vowel is a "long o" instead of a "short o". Since the term entered the popular lexicon in a more general context, the spelling clone has been used exclusively.3. Reading aloud to the recordingWhole language teachers affirm that reading aloud teaches you the students about language in a way that silent or independent reading never can.Reading aloud to the tape helps you the students develop and improve language skills -- reading, writing, speaking, and listening. And since you the students listen on a higher level than you read, listening to other readers stimulates growth and understanding of vocabulary and language patterns.So why not hurry to listen and read to the tape-recording of the text we are going to learn today?4. Reading for formsRead the text again to: cut/ the sentence into thought groups, blacken the predicates, darken the connectives and underline all the useful expressions.5. Reading for the type of writing and summary of CLONING：WHERE IS IT LEADING US? Determining the type of writing will help you determine the author’s topic (subject), purpose (why he is writing), style (how he should write) and tone (his attitude towardhis subject - supportive, condeming, objective, etc.)It is important to find main ideas when reading. Main ideas help you remember important information. The main idea of a paragraph tells the topic of the paragraph. The topic tells what all or most of the sentences are about. The other sentences in the paragraph are called details. Details describe or explain the main idea. Read the text to find the main idea.6. Copying and making sentencesYou are asked to copy all the useful expressions into your notebook after class as homework. You may make your own sentences with each of these expressions.7. Reading and transforming8. Reading the text again to draw a diagram of it and retell the story with your own wordsWriters structure, or organize, their writing in many different ways. Recognizing the way in which a text has been organized will help you understand its meaning more fully.9. Closing down by learning more about DollyTo end this class, let’s get to know more about Dolly.Celebrity Sheep Has Died at Age 6Dolly, the first mammal to be cloned from adult DNA, was put down by lethalinjection Feb. 14, 2003. Prior to her death, Dolly had been suffering from lung cancer and crippling arthritis. Although most Finn Dorset sheep live to be 11 to 12 years of age, postmortem examination of Dolly seemed to indicate that, other than her cancer and arthritis, she appeared to be quite normal. The unnamed sheep from which Dolly was cloned had died several years prior to her creation. Dolly was a motherto six lambs, bred the old-fashioned way.。

选修8 Unit2 Cloning-Reading 教学设计与反思
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.
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。
