Lesson 1 P52-55新新北师大选择性必修北师大选择性必修Book 3 Unit 9 HUMAN BIOLOGY TO CLONE OR NOT TO CLONEIn 1996,the worlds first cloned animal was born.It was a sheep named Dolly.Dolly was generated by an adult sheeps somatic cell.In 1997,the first cloned mouse named Cumulina was born in Hawii,and died a natural death from old age(34 months)in 2000.In 1998,the worlds first cattle is replicated from a somatic cell in Japan.And then they produced cloned beef and milk.In 2000,scientists cloned a mouflon.It is the first time that cloning technology is applied to an endangered animal.In 2000,the worlds first successful cloning of primates genetically closest animals to humanwas born in the Oregon area.In 2001,it was announced that the first five transgenic cloned pigs were born.They can provide organs for humans.1What do you know about cloning?What additional information would you like to know?Use the words and phrases to help you.cellspeciesto edit genesidentical genesto develop artificiallyto make an exact copy ofto break the technical barrierto produce animal modelsWhat is cloning?Cloning is a technique scientists use to make exact genetic copies of living things.Genes,cells,tissues,and even whole animals can all be cloned.Read through the article.Draw a structual map to show how the paragraphs are organised.2To clone or not to clonedefinition of cloningcloningopinionswriters attitude about cloningnatural cloningfirst cloningpositive opinionsnegative opinionsfirst-cloned primates3Group Work.Read paragraphs 1-4 and make detailed notes about cloning that better illustrate the information.Then share your notes in a small group.4Pair Work.Read the first four paragraphs again.Ask and answer the questions in pairs based on your notes.1.What is cloning?2.What examples of natural cloning are given?Cloning is the process of making an exact copy of a plant or animal and developing it naturally and artificially.An example of natural cloning is taking a cutting from a plant and putting it in soil,and another is identical twins.3.What was the first cloned mammal?What happened to her?4.How has the science of cloning developed since the first cloned mammal?The first cloned animal was Dolly the sheep.She developed an illness and died when she was six and a half years old.Scientists have been able to clone animals of other species.5.What development in cloning was announced in 2018?What was special about it?6.For how long did Dr.Sun Qiangs team work?Why did they work so hard?In 2018,the first two long-tailed monkeys were cloned.Cloning a primate is more difficult than cloning other animals.Dr.Sun Qiangs team worked for more than five years in order to get animals with edited genes and produce animal models.5Group Work.Read paragraphs 5-6.List the potential benefits of,and moral concerns about cloning primates.Add your own concerns.Then share your notes in groups.Cloning primatesPotential benefitsMoral concernscures for diseases,prevent aging,save research time,reduce the number of animals being tested on,producing more accurate results,better treatmentclones should be treated as objects or individuals,clones are inferior,some organisations may abuse the technology6Read the last paragraph.What does Einsteins quote mean?Einsteins quote means that science itself cant be judged as good or bad,because it can only function when it is used by humans.He also indicates humans need to be careful with the information they learn through science and to remember to use science for good.“Science is a powerful instrument.How it is used,whether it is a blessing or a curse to mankind,depends on mankind and not on the instrument.A knife is useful,but it can also kill.”7Pair Work.Talk about cloning using the information in the article.Cloning01 Definition02 Natural cloning03 First cloning04 First-cloned primates05 Positive and negative opinions06 Writers attitudeCloning is a scientific process of making copy of a plant or an animal and developing it either naturally or artificially.Lets talk about cloning.8Group Work.Think and share.1.Why do researchers insist that the science of cloning should be further explored and advanced?2.What is the writers attitude towards cloning?Five evidence.Researchers insist on explore cloning to continue making progress in curing diseases and developing treatments.The writer feels that cloning can be a helpful tool in medical research but that it can also become dangerous.Evidence of this is in the writers use of Einsteins quote.9Read the first sentence of each paragraph.Are there any single words,such as linking words or time expressions,that help to make the article coherent.10Complete the summary using the information in the article.Natural cloning has taken place for generations.An example of this is identical 1 _.A sheep called Dolly was the first mammal to be cloned 2 _.Since Dolly,more than 20 mammal 3 _ have been cloned including camels and goats.In 2018,China
