人教版高中英语选修8Unit2《Cloning》word教案【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，陈老仍旧执著于此。

然而爱护大熊猫，怎么说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 voice s 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 tosave endangered animals，”Chen said.Some scientists take a different vie w.“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)●教学目标本课时要紧是通过学生对学案所给出的内容的学习，了解本课文中所显现的词汇，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明白得起到一个铺垫作用。

人教版高中英语选修八unit2 Cloning

高中英语学习材料madeofjingetiejiunit2 CloningⅠ.阅读理解AThere are many ways in which human cloning is expected to benefit humans.Dr Richard Seed, one of the leading supporters of humancloning technology, suggests that it may someday be possible tocompletely change the aging process because of what we learn fromcloning.Scientists believe that they may be able to treat heart attackvictims by cloning their healthy heart cells and injecting them into the areas of the heart that have been damaged. Heart disease is the number one killer in the US and several other industrialised countries.There has been a breakthrough with human stem cells. Embryonic stem cells can be grown to produce organs to repair or replace damaged ones. Skin for burn victims, brain cells for the brain damaged, hearts, lungs, and kidneys could be produced. By combining this technology with human cloning technology, it may be possible to produce needed organs for suffering people that will be free of rejection by their immune systems. Conditions such as Alzheimer’s disease, Parkinson’s disease, heart failure, and other problems can be cured if human cloning and its technology are not banned.Though current treatments for infertility (不生育) are getting a fair amount of publicity in the news, they, in terms of percentages, are not very successful. Some data shows that current infertility treatments are less than 10 percent successful. Couples go through physically and emotionally painful procedures for a small chance of having children. Many couples run out of time and money without successfully having children. Human cloning could make it possible for many more infertile couples to have children than ever before possible.语篇解读：本文作者从几个方面介绍了克隆人技术给人类带来了利益。
