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.。

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 being 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 c loningis 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。
