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.。

号顿市安谧阳光实验学校Unit 2 CloningPeriod 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?。

Human cloning is the creation of a genetically identical copy of an existing or previously existing several highly public claims，human cloning still appears to be a is no solid scientific evidence that anyone has cloned human embryos at present.In 2023，a group in South Korea published a paper in the journal Science in which it claimed to have created a cloned human embryo in a test ，an independent scientific institute later found no proof to support the claim and，in January 2023，Science announced that the paper had been withdrawn.In January 2023，Dr Samuel Wood and Dr Andrew French in California announced that they successfully created the first 5 fully grown human embryos using DNA from adult skin cells，aiming to provide a source of viable embryonic stem Dr Wood stated that if that were possible，using the technology for reproductive cloning would be both immoral and 5 cloned embryos were destroyed.The various forms of human cloning are scientific，governmental and religious organizations oppose reproductive ，some people have considered the idea of growing organs separately from a human organism—in doing this，a new organ supply could be established without the moral

根据第一段的“...send out a particular smell that neighboring plants c an get.These chemicals come from the injured parts of the plant...”可知,当植物受到袭击时,它们会释放出某种化学物质。
因此D项正确。
2.What does the author mean by “the tables are turned” in paragraph 3?A.The attackers get attacked.B.The insects gather under the table.C.The plants get ready to fight back.D.The perfumes attract natural enemies.答案:A解析:词义猜测题。
前文说,有些植物释放出一些难闻的化学物质赶走害虫,而另一些植物会释放出一些香味吸引这些害虫的天敌。
一旦这些天敌到达,这些害虫就会受到攻击,因此the tables are turned的意思是“攻击者受到攻击”,故A项正确。
3.Scientists find from their studies that plants can .A.predict natural disastersB.protect themselves against insectsC.talk to one another intentionallyD.help their neighbors when necessary答案:B解析:推理判断题。
根据第四段可知,研究表明,植物们能保护自己不受害虫的侵袭。
4.What can we infer from the last paragraph?A.The world is changing faster than ever.B.People have stronger senses than before.C.The world is more complex than it seems.D.People in Darwin’s time were more imaginative.答案:C解析:推理判断题。
