afternoon，ladies and gentlemen.Thank you all for coming to this lecture.Over the course① of my career，I have seen many wonderful scientific developments，but none are as game-changing② as genome editing③.I am full of excitement about the possibilities this scientific advance can bring and I hope to share my excitement with you today. “as＋形容词＋as”意为“和……一样……”。 定语从句，省略了关系代词that或which。 ①course

女士们，先生们，下午好！谢谢大家来听这个讲座。在我的职业生涯中，我见证了许多了不起的科学发展，但没有一个能像基因组编辑那样具有颠覆性。我对这一科学进步所能带来的种种可能性感到万分激动，我希望今天能与你们分享这份兴奋之情。 As many of you may already know，genes play a critical role in④ 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 cell⑤ or a living being⑥ is called a genome.Our own personal genome carries all the information needed to make us grow and develop.It also contains information that helps determine our lifespan⑦ and affects⑧ our chances of contracting⑨ certain diseases.Some people，for example，carry a gene that makes them more likely to catch a certain virus⑩ or develop a particular form of cancer⑪. 过去分词短语作后置定语。 that引导定语从句，在从句中作主语。 that引导定语从句，在从句中作主语。 ④play a critical role in...在……中起至关重要的作用 ⑤cell/sel/n.[C]细胞 ⑥being/'biːIŋ/n.[C]生物；[U]存在；身心 　human being n．[C]人 　for the time being 目前 ⑦lifespan/'laIfspæn/n.寿命，有效期 ⑧affect/ə'fekt/vt.影响；侵袭，使感染；深深打动

你们很多人可能已经知道，基因在塑造我们的生命方面起着关键作用。从眼睛的颜色到我们的数学天赋，一切都取决于基因。基因组是指一个细胞或生物体内的一整套基因。我们的个人基因组携带着我们成长和发展所需的所有信息。它(基因组)还包含了有助于决定我们寿命长短和影响我们患某些疾病概率的信息。例如，有些人携带着一种让他们更有可能感染某种病毒或患上某种癌症的基因。 Geneticists have been trying to identify⑫ which genes relate to⑬ which diseases，as they believe genome editing is an effective means⑭ of disease treatment and prevention.It allows geneticists to make changes to the genome by correcting，adding，deleting⑮ or replacing specific parts of the genetic material.In the near future，geneticists hope to apply this technology to⑯ treat a wide range of health problems.Soon we may be able to use such treatments to restore⑰ a blind person's vision or give someone who was born deaf an excellent sense of hearing.Ultimately⑱，this new technology might even make it possible to prevent diseases from ever developing by correcting abnormal⑲ genes early on9.Genome editing，serving as⑳ a new weapon㉑ in the fight against diseases 10 ，will lead to a fundamental㉒ change in our approach to㉓ health care. which引导宾语从句。 as引导原因状语从句。 who引导定语从句。 it作形式宾语，不定式短语作真正的宾语。 10 现在分词短语作后置定语。 ⑫identify/aI'dentIfaI/vt.找到，发现；确认，认出；显示，说明身份 ⑬relate to 涉及，与……相关 　relate/rI'leIt/vi.&

㉓approach to...……的方法 遗传学家一直试图找出哪些基因与哪些疾病有关，因为他们认为基因组编辑是治疗和预防疾病的一种有效手段。基因组编辑允许遗传学家通过纠正、增加、删除或替换遗传物质的特定部分对基因组进行修改。在不久的将来，遗传学家希望将这项技术应用于治疗各种各样的健康问题中。也许我们很快就能利用这些疗法来恢复盲人的视力，或者让先天性耳聋的人拥有敏锐的听力。最终，这项新技术甚至有可能通过早期纠正异常基因来预防疾病的发展。作为对抗疾病的新武器，基因组编辑将给我们的医疗保健手段带来重大变革。 As the technology continues to develop at a fast pace㉔，however，questions arise㉕ about how to use it appropriately.Should we restrict㉖ our use of this technology to the treatment and prevention of diseases？Should we prohibit geneticists from using㉗ it to enhance healthy bodies？One day soon we will be able to use genome editing to increase the human resistance㉘ to colds and flus㉙，to make people taller，to help their muscles develop faster，to sharpen㉚ all of their senses or to make them more intelligent 11.We will also be able to select specific characteristics㉛ for children before they are born，creating what some have called “designer babies” 12.However，is this a good thing？What consequences㉜ might it have？Philosophers，geneticists and government officials have all started to wrestle with㉝ such moral issues.We have to figure out㉞ how to keep the technology from running㉟ wild 13.This means putting appropriate controls in place㊱ to make sure that genome editing will work to our advantage㊲ 14.Without them，genome editing could be as dangerous as a car out of control㊳.15 11 此处为不定式短语作目的状语的并列结构。 12 现在分词短语作结果状语，其中what引导宾语从句。 13 “疑问词＋不定式”结构作宾语。 14 that引导宾语从句。 15 此处为含蓄虚拟语气。

失去控制 然而，随着这一技术不断迅速发展，出现了如何合理使用它的问题。我们是否应该将这项技术的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使用它(基因组编辑技术)来使健康的身体更加强健？不久的将来，我们将能够利用基因组编辑来增强人类对感冒和流感的抵抗力，使人类长得更高，促进他们的肌肉更快发育，提高他们所有的感官的敏锐程度，或使他们更聪明。我们也将能够在孩子出生前为他们选择特定的特征，创造一些被称为“设计婴儿”的孩子。然而，这是一件好事吗？可能会有什么后果呢？哲学家、遗传学家和政府官员都已开始全力解决这样的道德问题。我们必须想办法防止技术失控。这意味着适当的管制要准备到位，以确保基因组编辑会对我们有利。没有它们(适当的管制)，基因组编辑可能会像失控的汽车一样危险。 There is still much to be explored and debated㊴ on the subject of genome editing.Despite the public argument over this technology 16，its possibilities have been creating much excitement throughout the entire medical community and beyond.Without doubt㊵，genome editing is one of the greatest inventions in the history of science.Thank you for listening. 16介词短语作让步状语。 ㊴debate/dI'beIt/vt.&

Would the injured person get the best possible care? When an accident happens, a first-aid programme that meets the requirements of the law and is made to the type and size of the workplace can really make a difference between life and death, or between recovery and lasting disablement(伤残). Employers should make sure that all employees know where emergency information is posted at the workplace.The emergency notice should show the phone numbers of the closest ambulance service, rescue unit, fire police station, and hospital.The amount of time it takes to look up one of these important numbers can make a big difference to a seriously injured person.The place of first-aid equipment and rescue equipment should also be posted. All workplaces should have a person with first-aid or medical training in case of an emergency.First-aid equipment and supplies, including a variety of dressings and instruments, as well as an up-to-date first-aid book, should be stored where they can be reached quickly and easily in case of an accident.These supplies should be inspected frequently, making sure they are kept in sanitary (卫生的) and usable conditions and re-stored after use.Larger workplaces may need more than one fully-equipped first-aid bag. In lonely workplaces, emergency supplies and an action plan are especially important.At least one person trained in first aid should always be on-site (在现场的).If first aid is not given properly, it can sometimes hurt rather than help an injured person, or even be harmful to the person giving first aid. All workers should know who is trained to give first aid on-site, where first-aid equipment is put, and what medical professionals or medical instruments should be found if a medical emergency happens. [语篇解读]　本文是一篇说明文。文章讲述了在工作场所也应该配备急救设备、药物、能施救的人员等，也说明了其重要性。 4 5 6 7 4．What is paragraph 2 mainly about? A．The importance of a proper first-aid programme at the workplace. B．The possibility to make a first-aid programme. C．The requirements of the law about a first-aid programme.

A．Be responsible for the result of the injured person. B．Know the exact place of first-aid equipment. C．Be trained to give first aid to the injured in an accident. D．Be far away from the accident place. 答案：B 4 5 6 7 细节理解题。根据最后一段的内容可知，所有工作人员都应该知道谁受过现场急救培训，急救设备放在哪里，如果发生医疗紧急情况，应该找到什么医疗专业人员或医疗器械。由此可知，作者认为所有工作人员都应该知道谁能够实施急救，急救设备放置位置，以及如果发生医疗紧急情况，应该找到什么医疗专业人员或医疗器械。故选B项。 4 5 6 7 C In recent years, advancements in artificial intelligence (AI) have brought both excitement and concerns to various fields.One area where AI is making a profound impact is the medical field, particularly in the domain of diagnostics. AI-powered diagnostic systems leverage deep learning algorithms to analyze medical images, such as X-rays, MRIs, and CT scans.These algorithms can detect subtle patterns and anomalies that might be missed by human radiologists, potentially leading to earlier and more accurate diagnoses. However, the integration of AI in medical diagnostics raises complex ethical questions.For instance, who should be held responsible if an AI system misdiagnoses a patient's condition? Should AI algorithms be treated as medical professionals, with legal and liability implications? These questions become even more intricate when considering that AI systems learn from vast datasets of medical information, which might contain biases or inaccuracies. Furthermore, the adoption of AI diagnostics could impact the role of healthcare professionals.Some argue that AI could enhance doctors' capabilities by providing them with additional insights, while others fear that it might replace human expertise, leading to job losses and a potential decrease in the quality of patient care.Despite these challenges, proponents of AI diagnostics emphasize its potential to improve healthcare accessibility, especially in underserved regions where there is a shortage of skilled medical professionals.AI-powered diagnostics could provide preliminary assessments and recommendations, helping to bridge the gap between patients and healthcare providers.
