Disapproving B. Doubtful C. Neutral D. SupportivePost-readingLet’s read a news about genetically edited babiesA Chinese researcher, He Jiankui, shocked the world two weeks ago when he revealed that the world’s first genetically edited babies had been born. Jiankui claimed to have edited embryos(胚胎) before implanting(移植) them into the mother.Jiankui used a easy gene-editing technology to disrupt the gene for CCR5. He claimed that disruption of CCR5 would ensure that these babies would be protected from contracting HIV infection.Since his bold announcement via YouTube, the scientific community at-large – both in the United States and in China – has strongly condemned this work as deeply unethical (不道德的) and dangerous.(2018 Nature’s 10: Ten people who helped shape the science stories of 2020)1. The lecturer mentions that one day we will be able to create “designer babies”.What do you think of “designer babies” Can you list its pros or cons Post-reading1. Designer babies can be perfectly healthy.2. Designer babies can be stronger and cleverer.3. Designer babies help further the cause(事業(yè)) of science.4. Designer babies may have longer lifespan.5. Designer babies can maintain a healthy gender ratio, the balance of males and females.ProsWhat do you think of “designer babies” Can you list its pros or cons Cons1. Designer babies will not be a success story all the time.2. Designer babies can cause a rift (分歧,裂縫) in the social balance.3. Designer babies would be manufactured(已制成的) sothere would be no individuality (個(gè)性).What do you think of “designer babies” Can you list its pros or cons 2. What controls can we put in place to make sure that genome editing will work to our advantage Post-readingTips: Governments ......Global organizations ......The public ......How What ......Governments around the world should work together to make laws and regulations about when genome editing can and cannot be used.First, these laws and regulations should cover various aspects of genome editing, such as ethical issues and security, and they may have to be introduced at multiple levels—global, national and even regional.Second, genome editing equipment needs to be strictly controlled so that it does not get into the wrong hands.Finally, governments, scientists, stakeholders(利益相關(guān)者) and the public need to work together to enforce(實(shí)施,執(zhí)行) appropriate usage of genome editing.SummaryGenome editing is one of the greatest inventions in the history of science , and we should put appropriate controls in place to make sure that genome editing will work to our advantage.Thank you. 展開更多...... 收起↑ 資源預(yù)覽 縮略圖、資源來源于二一教育資源庫
