Supportive 13 Post-reading Let’s read a news about genetically edited babies 15 A 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） What is the attitude of the the scientific community? Why the scientific community has strongly shown its disapproval of this work? 1.人类毕竟是人类，而不是小白鼠，不应该被拿来做实验。 2.基因编辑也违背了一个人的自决权。 3.基因编辑技术也会加剧社会的不公，两极分化越来越严重。 4.所谓的生命体的优势，在不同的时期、不同的环境下，也是没有固定标准的。 5.如果未来大家全都通过基因编辑技术来养儿育女，那么大家都会选择公认的“优势”基因进行遗传。 16 The lecturer mentions that we will create “designer babies”.

Today's harvest 未来就在我们的基因里 Good afternoon, ladies and gentlemen. Thank you all for coming to this lecture. Over the course of my career, I have seen many wonderful scientific developments, but none are as game-changing as genome editing. I am full of excitement about the possibilities this scientific advance can bring and I hope to share my excitement with you today. para.1 女士们、先生们，下午好。感谢各位来到本场讲座。在我的职业生涯中，我见证过许多了不起的科研成果，但没有一项能像基因组编辑一样具有颠覆性。我对这项科学进展能够带来的可能性兴奋不已，并且希望在今天与各位分享这份兴奋之情。 As many of you may already know, genes play a critical role in shaping our lives. Everything from the colour of our eyes to our talent for maths depends on genes. The complete set of genes inside a cell or any living being is called a genome. Our own personal genome carries all the information needed to make us grow and develop. para.2 在座的很多人可能已经知道，基因对于塑造生命起着决定性作用。从眼睛的颜色到数学天赋，一切都取决于基因。一个细胞或一个生物体内的一套完整的基因就称为一个基因组。每个人自己的基因组都携带着各自生长发育所需的全部信息。 It also contains information that helps determine our lifespan and affects our chances of contracting certain diseases. Some people, for example, carry a gene that makes them more likely to catch a certain virus or develop a particular form of cancer. 基因组包含的信息也有助于决定我们的寿命长短并影响我们罹患某种疾病的概率。比如，有些人携带的某个基因会使他们更易感染某种病毒，或是患上某种特定类型的癌症。 para.2 Geneticists have been trying to identify which genes relate to which diseases, as they believe genome editing is an effective means of disease treatment and prevention. It allows geneticists to make changes to the genome by correcting, adding, deleting or replacing specific parts of the genetic material. In the near future, geneticists hope to apply this technology to treat a wide range of health problems. para.3 遗传学家相信基因组编辑是治疗和预防疾病的一种有效手段，因此他们一直试图找出哪些基因与哪些疾病有关。基因组编辑使得遗传学家可以通过修正、嵌入、移除或替换基因材料的特定部分来改变基因组。在不久的将来，遗传学家期待运用这项技术解决多种健康问题。 Soon we may be able to use such treatments to restore a blind person's vision or give someone who was born deaf an excellent sense of hearing. Ultimately, this new technology might even make it possible to prevent diseases from ever developing by correcting abnormal genes early on. Genome editing, serving as a new weapon in the fight against diseases, will lead to a fundamental change in our approach to health care. 也许我们很快就能用这些疗法帮助盲人恢复视力，或使先天性耳聋患者获得敏锐的听力。最终，这项新技术甚至有可能通过 及早修正异常基因来预防疾病。基因组编辑技术作为对抗疾病的一种新武器，将从根本上改变我们的医疗保健方式 para.3 As the technology continues to develop at a fast pace, however, questions arise about how to use it appropriately. Should we restrict our use of this technology to the treatment and prevention of diseases? Should we prohibit geneticists from using it to enhance healthy bodies? One day soon we will be able to use genome editing to increase the human resistance to colds and flus, to make people taller, to help their muscles develop faster, to sharpen all of their senses or to make them more intelligent. 然而，随着基因组编辑不断迅猛发展，如何恰当地利用这项技术成为了问题。我们是否应该将其应用限制在治疗和预防疾病方面？我们是否应该禁止遗传学家利用它来优化健康的身体？不久之后，我们将能利用基因组编辑技术提高人体对感冒和流感的抵抗力，也能让人长得更高、肌肉生长得更快，让人体的各种感官更加灵敏或者智商更高。 para.4 We will be able to select specific characteristics for children before they are born, creating what some have called “designer babies”. However, is this a good thing? What consequences might it have? Philosophers, geneticists and government officials have all started to wrestle with such moral issues. We have to figure out how to keep the technology from running wild. This means putting appropriate controls in place to make sure that genome editing will work to our advantage. Without them, genome editing could be as dangerous as a car out of control. 我们也将能够在孩子出生前就为他们选择特定的特征，制造出有些人所谓的“设计婴儿”。但这是一件好事吗？会有什么后果？哲学家、遗传学家和政府官员都已着手设法解决这些道德问题。我们必须想办法防止这项技术失控。这意味着我们需要采取恰当的管制措施，以确保基因组编辑对人类有利。否则，它可能会像失控的汽车一样危险。 para.4 There is still much to be explored and debated on the subject of genome editing. Despite the public argument over this technology, its possibilities have been creating much excitement throughout the entire medical community and beyond. Without doubt, genome editing is one of the greatest innovations in the history of science. Thank you for listening. para.5 对于基因组编辑这一话题，要探索和讨论的还有很多。虽然公众对这项技术存在争论，但它蕴含的可能性让整个医学界和外界都感到非常兴奋。毫无疑问，基因组编辑是科学史上最伟大的发明之一。感谢各位聆听。 Thank you null 4702.0415 Lavf58.51.100 Lavf57.71.100 Packed by Bilibili XCoder v2.0.2 $
